Safety Instructions

During the design and production of Husqvarna products,

great importance is placed on safety, as well as effective-

ness and ease of use. To ensure that the machine remains

safe you must pay attention to the following points:

WARNING!

This machine is only intended for use

together with a Husqvarna PP 455E or a

unit connected to Husqvarna RC 455. All

other use is forbidden.

CAUTION

Under no circumstances may the machine be

started without observing the safety

instructions. Should the user fail to comply

with these, Husqvarna Construction Products

Sweden AB or its representatives are free

from all liability both directly and indirectly.

Read through these operating instructions and

make sure that you understand the contents

before starting to use the machine. Should

you, after reading these safety instructions,

still feel uncertain about the safety risks

involved you must not use the machine Please

contact your dealer for more information.

• Check that all couplings, connections and hydraulic

hoses are in full working order.

• Make sure that all hoses are connected to the machine

correctly before you start the machine.

• Make sure that there are no persons or animals in the

working area.

• Check that the guard is not broken and that it is ﬁtted

correctly.

• Never cut without using the guard.

• Never disconnect the hydraulic hoses without ﬁrst

shutting off the hydraulic unit and ensuring the motor

has stopped completely.

• Check the machine, couplings and hydraulic hoses

daily for leakage. A rupture or leak can cause a

”hydraulic ﬂuid injection” in the body or result in other

serious physical injury.

• Do not exceed the speciﬁed hydraulic ﬂuid ﬂow or

pressure for the tool being used. Too high pressure can

result in rupturing.

• Do not misuse hoses.

• Do not use hoses that are distorted, worn, or

damaged.

• Check that the hoses are connected correctly to the

machine and that the hydraulic couplings lock as

intended before pressurising the hydraulic system. The

couplings are locked by turning the outer sleeve on the

female coupling so that the slot moves away from the

ball.

• Keep the hydraulic hoses and couplings free from dirt.

• Always switch off the power to the hydraulic unit before

moving equipment.

• Always saw in a manner that permits easy access to

the emergency stop.

• Never leave the machine unsupervised with the motor

running.

• Clearly mark out all cuts to be made before you start

sawing, plan these so they can be carried out without

danger to persons or the machine.

• Check with building drawings whether electrical cables,

water pipes, gas pipes or sewage pipes have been

routed within the working area.

• Always check and mark out where gas pipes are

routed. Cutting close to gas pipes always entails

danger. Make sure that sparks are not caused when

cutting in view of the risk of explosion. Remain

concentrated and focused on the task. Carelessness

can result in serious personal injury or death.

• Check that electrical cables within the working area are

not live.

• Hoses that are marked and approved as electrically

non conductive must be used when using hydraulic

tools on or in the vicinity of electrical cables. The use of

other types of hoses can result in serious physical

injury or even death.

• Observe care when lifting. You are handling heavy

parts, which implies the risk of pinch injuries or other

injuries.

• Personal protective equipment and protective clothing

as set out in the Operator's manual must always be

worn. Never wear loose ﬁtting clothes that can catch in

moving parts.

• Only use wire recommended by the manufacturer.

• Never cut without using the cooling water. A poorly

cooled wire can result in the segments overheating,

which results in greater wear. In the worst case

scenario, segments can come loose from the wire and

injure persons close to the saw.

Operator's Manual CS 2512

Introduction

Husqvarna CS 2512 is designed for use together with the

hydraulic unit PP 455 E or Husqvarna RC 455. Husqvarna

CS 2512 is a powerful and easy to use wire saw with a

capacity for really large work, yet at the same time

sufﬁciently compact and mobile for small work. It can be

used in many different ways, both on the ground and ﬁtted

to the wall.

The well thought-out design of the CS 2512, where the

drive wheel is placed on the machine's output side means

that the wire is always under tension even when the feed

force is low. Combined with the adjustable pressure valve

this gives exact control of cutting and unbeatable

performance.

The machine can be rigged both vertically and horizontally

and many cuts can be made directly without external idler

wheels.

Complete saw equipment consists of:

1 x saw unit

1 x accessory box

1 x 18 mm wrench

1 x pressure reduction block

1 x extra wear rubber for the magazine wheel

1 x cleaning brush

Operator's Manual CS 2512

What is what

The saw consists of the following component parts:

1. Hydraulic motor

The machine is powered by a 60 cubic centimetre

motor. The motor has two parts, one of 50 cubic

centimetres and a smaller part of 10. Two gears are

obtained by using either just the large motor or both

the large and small motors together. The two gears

give different speeds, yet the same power.

2. Hydraulic hose connections

The hydraulic ﬂow in the two large hoses drives the

machine's motor and with that the wire. The ﬂow in the

two smaller hoses drives the magazine cylinder.

3. Drive wheel

Transfers the motive force from the motor to the wire.

The drive wheel is 400 mm in diameter and is covered

with replaceable rubber to give as good grip as

possible between the drive wheel and wire.

The drive wheel forms together with the hydraulic

motor and the hydraulic connections

the drive wheel

unit.

The drive wheel unit is adjusted depending on

how many wheel sets are used in the magazine. These

can easily be dismantled to give a lighter machine

during transporting.

4. Wire magazine

Tensions the wire and stores recovered wire. The wire

magazine has a capacity to store a maximum of 12

metres of wire (2.4 metres per wheel set).

5. Magazine cylinder

The magazine cylinder tensions the wire in the

magazine and with that governs cutting. The pressure

in the cylinder is adjusted by means of the pressure

reduction block ﬁtted on PP 455E or RC 455.

6. Guard

The machine has a two-piece guard. A ﬁxed part made

of sheet metal and a folding cover made of plastic and

metal. The guard is easy to remove, e.g. when the wire

is threaded, it should always be ﬁtted in position when

cutting.

7. Lifting handle

The folding handle is the perfect aid when transporting

the machine.

8. Adjustable feet

Adjusted so the saw stands ﬁrmly. In total, the saw

features 10 feet, six for horizontal cutting and four for

the vertical position.

9. Cooling water connections

There are two connections on the machine for water

spears and one for the incoming water. Besides

cooling the wire with these, the wire is also rinsed

when it returns to the machine and when it leaves the

machine by small nozzles.

10.Rubber wheels

To facilitate transport. The wheels can be dismantled in

some situations to facilitate access on certain jobs.

This is done by removing the split pins that lock the

wheels on the wheel axle.

11.Wire boom

Holds the wire in against the magazine when the

magazine is run in. This prevents the wire tangling

when not tensioned, e.g. when changing the wire or

when changing the number of wheels used in the

magazine.

12.Anchor beam

Adjustable beam with a longitudinal slot. By moving

this beam sideways, you can position the anchor bolt in

a suitable position without the need of moving the

entire saw when anchoring the saw before cutting.

An additional anchor beam is placed under the saw.

The anchor bolt is secured in this beam when

horizontal cutting.

13.Pressure reduction block

The pressure reduction block is ﬁtted between the

hydraulic unit and the hydraulic hoses for the input

supply. There is a valve located on the pressure reduc-

tion block, this is used to control the magazine tension.

14.Swivel wheels

The swivel wheels supported on bearings are located

where the wire enters the saw and out through the

saw. The swivel wheels help to guide the wire so it is

positioned correctly in the saw and can either be

locked in a ﬁxed position or used in the unlock position

so that the wheels follow the wire.

15.Guide wheel

Guides the wire from the magazine to the drive wheel.

When the drive wheel unit is adjusted, the guide wheel

is set automatically depending on the number of

magazine wheels used.

Accessories

1. Water spear

Connected to the water connections on the saw and

used to guide cooling water into the cut to cool the wire

and to bind the concrete dust.

2. Idler wheels

Husqvarna idler wheels are designed to smoothly

guide the wire as efﬁciently as possible. By using idler

wheels the number of sharp corners to cut around can

be reduced, which means that more of the cutting

capacity is used for material removal.

3. Cleaning brush

Can be connected to the water hose and then used to

clean the machine after use.

WARNING

Under no circumstances may

modiﬁcations be made to the machine

without written permission from

Husqvarna Construction Products Sweden

AB. Non approved modiﬁcations put you

and others at risk of serious or fatal

injuries. Husqvarna Construction Products

Sweden AB bears no responsibility for

Recommended wires:

Husqvarna recommends that the following wires are used:

• Husqvarna C710C

Husqvarna C710C is a galvanised wire developed for

use when cutting concrete with a great deal of

reinforcement. The segments have a great number of

diamonds and a smaller diameter (9.5mm) which

means the wire cuts very efﬁciently. The smaller

diameter also means that C710C can be used to ﬁnish

difﬁcult cuts.

• Husqvarna C750C

Husqvarna C750C is an all round wire developed for

use when cutting reinforced concrete. The wire has

been designed for use with saws with an output power

between 10 and 25 kW.

• Husqvarna C760C

This is the Husqvarna premium wire: long life, high

cutting rate and high power resistance characterize

this wire. Husqvarna C760C can be used to cut all

types of reinforced concrete, even when the work

places high demands on the wire, for example when

cutting bridges.

• Husqvarna C790C

The segment strength on this wire makes Husqvarna

C790C the best choice when cutting soft materials

such as mortar, and lightly reinforced limestone

concrete.

• Husqvarna C575J

Husqvarna C575J is a wire with galvanised 15 mm

segments.

• Husqvarna C1200M

Husqvarna C1200M is a wire developed for use when

cutting steel. The wire has been designed for use in

extremely demanding situations. The use of the latest

sintering technique has given enormous advantages

with regard to cutting rates and life span. The wire can

be supplied with either joined or loose ends.

Assembling/Installing

equipment

Cutting needs to be planned carefully before assembling

the saw so that it can be performed as easily as possible.

Husqvarna CS 2512 can be assembled to make either

horizontal or vertical cuts. The saw is assembled standing

when you wish to make vertical cuts.

The saw is assembled horizontally when the cut is to be

made at ﬂoor height and when the cut is made in the ﬂoor.

It may be necessary to drill holes to thread the wire

through the material to be cut.

Position the saw in an appropriate position in front of the

planned cut. When the saw is in position, secure it by

screwing down the anchor bolt.

When the saw is anchored to the ﬂoor, screw down the

adjuster feet so that the saw stands ﬁrmly.

Remember that the machine's centre of gravity (the grey

circle) is positioned between the ﬁrst and second pairs of

adjuster feet (the adjuster feet pairs are marked 1-3) with a

horizontal cut (A). When cutting under the machine, it is

important that the saw is anchored well with the anchor

bolt (b) as the adjuster feet pairs 2 and 3 must be used.

(Adjuster feet pair 1 may rest on the sawn off section.) If

the saw is not anchored well it will overturn when the mate-

rial supporting adjuster feet pair 1 has been cut through.

If necessary, ﬁt idler wheels to assist the cutting process.

Using the idler wheels allows the number of sharp corners

that the wire must be pulled around can be reduced,

which results in less wear to the wire at the same time as

cutting is made easier. Using the idler wheels also lets the

wire be guided in different directions without the need of

moving the saw unit.

Also, use the idler wheels to capture the wire when

ﬁnishing the cut.

WARNING!

Always position the saw so that you can

stand without the risk of being hit by a

broken wire. Ensure that no unauthorised

persons can access the working area while

cutting. Being hit by a broken wire can

result in death or serious personal injury.

Operator's Manual CS 2512

Connection to the hydraulic unit

When the saw is assembled appropriately, it should be

connected to a hydraulic unit. Husqvarna CS 2512 is

designed for use with Husqvarna PP 455 or Husqvarna

RC 455.

1. Check that the hydraulic unit is connected to the power.

2. Connect the cooling water to the motor on the

hydraulic unit.

3. Check that the display on the remote control shows

“CONNECT HOSE BUNDLE”. If not follow the instruc-

tions in the Operator's manuals for PP 455E or RC 455.

4. Fit the two large hydraulic hoses on the unit ﬁrst and

then to the saw motor connections. Lock the couplings

by turning the sleeve on the coupling so that the slot

moves away from the ball.

5. Fit the pressure reduction block on the hydraulic unit as

set out in the instructions on the block.

6. Connect the two smaller hydraulic hoses to the

pressure reduction block. The hoses in the hose

bundle marked with a red disc by the coupling shall be

connected to the hose on the pressure reduction block

that is also ﬁtted with a disc.

Lock the couplings by turning the sleeve on the

coupling so that the slot moves away from the ball.

7. Fit the two hoses connected on the pressure reduction

block to the hoses to the feed cylinder on the saw. The

hoses in the hose bundle marked with a red disc by the

coupling shall be connected to the hose on the saw

that is also ﬁtted with a disc.

8. Connect the water hose to the incoming water on the

saw.

If the couplings jam when assembling, they should be

removed completely before being reﬁtted.

Make sure that the couplings on the hoses not in use do

not lie directly on the ground.

Always keep the couplings as clean as possible. A clean

coupling lasts longer.

Threading the wire

The guard can easily be lifted off to facilitate ﬁtting wire.

Now thread the wire as follows:

1. Make sure the magazine is in the min position.

2. Place the wire around the work piece, possibly through

the predrilled holes and back to the saw.

3. Thread the wire through the hole by the swivel wheel

and around a suitable number of wheel sets in the

magazine.

4. Adjust the drive wheel unit according to the number of

wheel sets used in the magazine:

Loosen the arm by screwing out the knob anti-

clockwise. Now turn the drive wheel unit so that the

arm is aligned with the markings on the saw. Lock the

drive wheel unit by turning back the knob.

Usually only one wheel set is used in the ﬁrst stage of

cutting.



Operator's Manual CS 2512

5. Thread the wire around the drive wheel and out

through the hole by the second swivel wheel. The

swivel wheel can rotate and be locked in the required

position by turning the marked (A) knobs.

6. Before the joints on the wire are connected, the wire

should be twisted 1 to 2 turns per metre wire used. It is

important to twist the wire in the same direction as it is

spun. This is to give as even wear as possible on the

wire’s diamond segments.

7. Lock the wire with a pin. If there are no end sleeves on

the wire, these must be spliced on to the wire. A

special pair of wire pliers must be used. If you are

unsure about which model you should use, contact

your Husqvarna dealer.

8. When the wire is routed correctly it should run through

the machine as in the ﬁgure below:

CAUTION

A used wire must always be run in the same

direction, as it was previously run in order to

prevent unnecessary wear.

Placement of the cooling water

Husqvarna CS 2512 is equipped with two outlets for the

cooling water. Ideally,Husqvarna water spears can be

connected to these. The water spears are then placed

where the wire enters the concrete. In this way the wire

takes water with it into the cut, which results in the

concrete dust binding and that the wire is cooled

efﬁciently.

CAUTION

In order for the water to cool the wire as

intended during cutting, it is essential to adjust

the position of the cooling water as the

material is cut. Remember to always stop the

machine when you do this.

In addition to the cooling water from the water spear, the

wire is rinsed by the two swivel wheels on the machine.

This is to keep the wire as clean as possible, which means

that the saw can work with less friction losses and greater

efﬁciency as the wire becomes cleaner.

Operation

Sawing

When all the equipment has been assembled cutting can

start. In order for the saw to cut as efﬁciently as possible it

should be started as follows:

1. Close the valve on the pressure reduction block by

turning the knob anti-clockwise until it stops and then

two turns back.

2. Start the hydraulic unit.

3. Set the feeding ﬂow on the unit to max by turning the

control on the remote control clockwise.

4. Tension the wire by carefully turning the knob on the

pressure reduction block clockwise until the wire is

tensioned sufﬁciently. Make sure to always check that

the wire is seated correctly in all the wheels on the

saw.

5. Start the motor's rotation by turning the control for

motor rotation on the remote control clockwise.

6. Carefully increase the motor speed by turning the

control for motor rotation. A suitable working pressure

when cutting usually lies between 100 and 130 bar, but

varies depending on how many wheel sets are used in

the magazine, how much wire is in use and the

hardness of the material to be cut.

7. As the material is cut away the working pressure

drops, which is shown on the display, and the

magazine must then be tensioned. Do this by turning

the knob on the pressure reduction block clockwise.

8. The output tension on the magazine is shown by an

indicator on the machine (shown in the min position).

When the magazine cylinder is fully tensioned, the

machine must be stopped and the wire must be wound

around a new wheel set. Then continue to cut as

above.

CAUTION

In order for the water to cool the wire as

intended during cutting, it is essential to adjust

the position of the cooling water as the

material is cut. Remember to always stop the

machine when you do this.

Finishing sawing

1. Lower the speed on the wire and allow the motor to

stop completely.

2. Fold up the magazine arm.

3. Disconnect the incoming mains cable from the

hydraulic unit.

4. Disconnect the hydraulic hoses and the water hose

from the saw unit.

5. Other steps are done in the reverse order.

22 - English

Operator’s manual

Cleaning

The saw should be cleaned once cutting is ﬁnished. It is

important to clean all the saw equipment. It is a good idea

to disconnect the water hose from the pivot arm and use

this to wash down the saw unit. If necessary, you can also

use the supplied cleaning brush or the like to clean the

equipment. Do not use a high pressure washer to clean

the saw.

Maintenance

In addition to the daily maintenance such as cleaning and

lubrication, the machine must be serviced. After 50 hours

of cutting, the machine should be serviced at an

accredited Husqvarna workshop. The saw should then be

serviced after every 100 hours of operation. The service is

important so that as the user you have a machine that

works as effectively as possible for a long time.

Lubrication

In order for the wire to run as friction free as possible, the

magazine axles must be ﬁlled with grease. Fill with grease

after every 5 -10 hours of operation. Use Canadian

Petroleum OG2 or similar grease.

The bearings on the magazine axles also need to be

lubricated regularly, but not as often as the magazine

axles.
