SPECIFIC SAFETY PRECAUTIONS

WARNING! DO NOT let comfort or familiarity with product (gained from

repeated use) replace strict adherence to the tool safety rules. If you use

this tool unsafely or incorrectly, you can suffer serious personal injury.

WARNING! Some surfaces contain materials which can be toxic. When

working on materials that may contain lead, asbestos, copper chromium

arsenate or other toxic materials, extra care should be taken to avoid

inhalation and minimize skin contact.

1. Use the correct tool for the job. This tool was designed for a specific

function. Do not modify or alter this tool or use it for an unintended

purpose.

2. Do not use the tool if any parts are damage broken or misplaced.

Repair or replace the parts.

3. Only use accessories that are specifically designed for use with the

tool. Ensure the accessory is tightly installed.

4. Do not use a dull or damaged cutting accessory. A dull cutting accessory

requires more force to use the tool, possibly causing the accessory to

break. This may cause an injury and will damage the workpiece.

5. Only use a cutting accessory that exceeds the No Load Speed rating

(see Specifications).

6. Always wait until the motor has reached full speed before starting a cut.

7. Never install more than one cutting accessory at a time unless the tool

and cutting accessories are designed for that purpose.

8. Use the correct mounting hardware. The mounting hardware is

designed to hold the cutting accessory on the tool to allow optimum

performance and safety of operation. Mismatched mounting hardware

may result in a tool malfunction and cause an injury.

a. Only use a cutting wheel with the correct arbor size and shape

that matches the tool’s spindle.

9. Inspect material for foreign objects such as staples, nails or debris.

Remove from material before cutting.

10. Do not subject the cut off wheel to any lateral pressure as it may

damage the tool or cause it to kickback.

POWER TOOL PRECAUTIONS

1. Do not use any power tool with a malfunctioning power switch or

control. A power tool that fails to respond to the controls is dangerous

and can cause an injury. A qualified technician must repair and verify

the power tool is operating correctly, before it can be used.

2. Do not cover the air vents.

3. Disconnect the power source before installing or servicing the tool.

4. Remove adjusting keys and wrenches before using the tool. The tool

may eject an attached wrench or a key and cause an injury to you or a

bystander.

5. Never force the tool. Excessive pressure could break the tool, resulting

in damage to your workpiece or serious personal injury. Excessive

pressure is the cause if your tool runs smoothly under no load, but

roughly under load.

6. Keep hands and fingers away from the work area. Any part of the body

contacting the tool’s working parts could result in an injury.

7. Before using the tool on a workpiece, test the tool by running it at the

highest no load speed for at least 30 seconds in a safe position. Stop

immediately if there is any abnormal vibration or wobbling. Check the

tool to determine the cause.

8. Never touch the tool accessory or workpiece during or immediately after

use. They may be hot and could inflict a burn injury.

9. Never use a tool with a cracked or worn tool accessory. Change the

tool accessory before using it.

10. Do not start the tool when the tool’s accessory is touching the workpiece.

11. Do not place the tool down until the tool’s accessory has stopped moving.

The accessory may catch the surface of work material and wrench itself

free, causing injury to the user and others in the work area.

12. Use extra caution when making a ‘plunge cut’ into existing walls or

other blind areas. You may cut objects that can cause kickback, cut an

electrical wire or a water pipe. The tool’s exposed metal surfaces may

convey a shock to the operator from a ‘live’ wire.

13. Gum and wood pitch hardened on an accessory slows the tool and

increases the potential for kickback. Remove the accessory from the

tool, then clean it with gum and pitch remover, hot water or kerosene.

Never use gasoline. Allow to dry before use. Discard the accessory if

the gum or pitch cannot be removed.

KICKBACK PRECAUTIONS

Kickback is a sudden reaction to a pinched or snagged cutting accessory.

The tool kicks out and away from the workpiece while the cutting accessory

is still active. This can inflict a serious injury on the user or a bystander.

Kickback can also damage the tool or workpiece.

Kickback can be avoided by taking proper precautions:

1. Maintain a firm grip on the tool and position your body and arms to allow

you to resist a kickback. Kickback will propel the tool in the direction

opposite to the cutting accessory’s teeth or direction of rotation. A

snagged rotary cutting cutting wheel may pull the tool out of your grasp.

2. If kickback occurs:

a. the cutting accessory may pass over a body part, causing a

serious injury;

b. a rotary cutting wheel may wrench the user’s arm causing muscle

or joint injuries; and

c. the tool may strike bystanders.

3. Use clamps or a vice to hold down smaller workpieces.

4. Use special care when working on corners, sharp edges or flexible

material. These workpieces have a tendency to snag the cutting accessory.

5. Only use cutting accessories designed for the tool.

6. Support large panels to minimize the risk of pinching the cutting

accessory. Large panels may sag under their own weight. Place

supports under the panel on both sides of the cutline. Place other

supports under the rest of the panels to prevent them from falling

after the cut.

AIR TOOL PRECAUTIONS

1. Use only clean and dry compressed air as a power source. Contaminated

or moist air will gradually damage the tool.

2. Install an in-line shutoff valve or regulator to allow immediate control

over the air supply in an emergency, even if a hose is ruptured.

3. Discontinue tool use if it does not work properly or air is leaking. Tag

or mark the tool as ‘defective’ or ‘out of service’ until repaired.

4. Check the manufacturer’s maximum pressure rating for air tools and

accessories. Compressor outlet pressure must be regulated to never

8843500 3 in. Air Cut-Off Tool V1.0

8 For technical questions call 1-800-665-8685

exceed the maximum pressure rating of the tool (see Specifications).

Exceeding the maximum PSI rating can create a bursting hazard,

causing injury and property damage.

5. Attach all accessories properly to the tool before connecting the air

supply. A loose accessory may detach or break during operation.

6. Never use oxygen, combustible gas or any other bottled gas as a

power source. Any power source other than an air compressor could

cause an explosion and serious personal injury.

7. Turn OFF the valve and discharge any remaining air pressure after each

use or before adjusting the tool.

8. Do not leave the air tool unattended with its compressed air supply on.

Turn off the compressed air supply and bleed the air tool of any

remaining compressed air before leaving the air tool unattended.

9. Serious injury may occur from loose debris being propelled at high speeds

from the compressed air stream. Always wear OSHA approved safety

glasses to protect the eyes during operation of the air compressor.

10. Always turn off the air compressor and drain tank pressure completely

before attempting maintenance or attaching air tools. Release pressure

slowly from the system.

11. Serious injury or death may occur from inhaling compressed air. The air

stream may contain carbon monoxide, toxic vapors or solid particles.

Never inhale compressed air directly from the pump or air tool.

AIR HOSE PRECAUTIONS

1. Inspect the tool's air hose for cracks, fraying or other faults before

each use. Discontinue use if the air hose is damaged or hissing is heard

from the air hose or couplers. Replace the defective air hose.

2. Do not allow people, mobile equipment or vehicles to pass over the

unprotected air hose. Position the air hose away from high traffic

areas, in a reinforced conduit or place planks on both sides of the air

hose to create a protective trench.

3. Prevent damage to the air hose by observing the following:

a. Never carry the tool by the air hose.

b. Keep the air hose behind the tool and out of the tool's work path.

c. Keep the air hose away from heat, oil, sharp edges or moving

parts.

2. Connect the tool to an air source.

3. Push the safety lever (B) forward, then press the trigger lever (C) down.

4. Allow the cutting wheel to attain full speed before proceeding to the task.

5. Align the cutting wheel with the workpiece. Keep the metal guard (A)

between yourself and the cutting wheel in case it breaks apart.

6. Apply gentle pressure to the tool and allow the cutting wheel to cut

through the workpiece. Too much force will slow the wheel and could

cause it to break.

7. Keep the tool steady during the cut. Do not attempt to move laterally

or twist the tool as it will break the cutting wheel.

8. Release the trigger once the cut is complete. Allow the wheel to stop

rotating before placing the tool down.

9. Stop the compressor once the task is complete and release residual

pressure from the tool and air hose. Disconnect the air hose from the tool.

PRESSURE DROP

the compressor’s outlet. Calculate the pressure drop for your air supply set-up

8843500 3 in. Air Cut-Off Tool V1.0

12 For technical questions call 1-800-665-8685

and increase the compressor outlet pressure to compensate. Make sure you do

not exceed the maximum pressure for any part of your air supply system.

Installing a pressure gauge at the tool inlet is the best way to measure the

air pressure and adjust the compressor’s output.

CARE & MAINTENANCE

1. Maintain the tool with care. A tool in good condition is efficient, easier

to control and will have fewer problems.

2. Inspect the tool fittings, alignment, hoses and power supply cord

periodically. Have damaged or worn components repaired or replaced by an

authorized technician. Only use identical replacement parts when servicing.

3. Follow instructions for lubricating and changing accessories.

4. Only use accessories intended for use with this tool.

5. Keep the tool handles clean, dry and free from oil/grease at all times.

6. Maintain the tool’s labels and name plates. These carry important

information. If unreadable or missing, contact Princess Auto Ltd. for

replacements.

WARNING! Only qualified service personnel should repair the tool. An

improperly repaired tool may present a hazard to the user and/or others.

AIR TOOL LUBRICATION

NOTICE! Only use air tool oil to lubricate the tool. Other lubricants are not

suitable and will damage the tool or cause a malfunction during use.

NOTICE! Never use a penetrating oil to lubricate an air tool. Penetrating oil

acts as a solvent that will dissolve the tool’s grease packing and may

damage the o-rings, causing the tool to seize or malfunction.

1. All air tools have an internal coating of grease to prevent corrosion

during shipping and storage. Remove this grease by adding a generous

amount of air tool oil in the air inlet and then run the tool under no

load until the exhaust is clear.

2. Manually add a drop or two of air tool oil into the tool’s male plug

before each use and after every hour of continuous use. The tool will

not work properly without lubrication and parts will wear prematurely.

3. Avoid adding too much air tool oil as this can cause premature power

loss and eventual tool failure. A qualified technician will need to take

the tool apart and clean out the excess oil.

V1.0 3 in. Air Cut-Off Tool 8843500

4. Apply a generous amount of air tool oil to the tool before storing it for

an extended period of time (overnight, weekend, etc.). Run the tool for

approximately 30 seconds to ensure the oil is evenly distributed

throughout the tool. Store it in a clean and dry location.

DISPOSAL

Recycle a tool damaged beyond repair at the appropriate facility.

Contact your local municipality for a list of disposal facilities or by-laws for

electronic devices, batteries, oil or other toxic liquids.
