3.3 Safety instructions

READ ALL INSTRUCTIONS!

Non-observance of the instructions listed below can cause electric shock, fire and/or serious injuries.

Work area

- Children and adolescents are not allowed to operate this machine.

- When using the machine outdoors, the use of an earth leakage circuit breaker is recommended.

- Replace damaged cables or plugs immediately. To avoid safety hazards, only MAFELL or an authorized

MAFELL service workshop is allowed to replace parts.

- Prevent sharp kinks of the cable. Do not wrap the cable around the machine, especially when transporting

and storing the machine.

- Do not use this machine when you are tired, or under the influence of drugs, alcohol or medicaments. Be

aware of what you are doing. Stay alert and use common sense.

- Keep children and bystanders at a distance while you are operating the machine. Distractions can cause

you to lose control of the machine.

- Use eye protection, dust mask and hearing protection. Appropriate safety equipment, used

under proper conditions, will reduce the risk of injuries.

Instructions for service and maintenance:

- Cleaning the machine regularly, especially the adjustment elements and the guiding devices, is an important

safety factor.

- Ensure that only genuine MAFELL spare parts and accessories are used. Failure to do so will make

warranty claims and the liability of the manufacturer null and void.

- Prepare a periodic maintenance schedule for your machine. When you clean the machine, be careful

not to disassemble any part of the machine. Reassembling the machine bears the risk that internal

wires are routed incorrectly or pinched, or that return springs of the safety device are mounted

incorrectly. Certain cleaning agents, such as gasoline, carbon tetrachloride, ammonia, etc. can damage

plastic parts.

- Some of the dust produced by sawing, sanding, drilling and other building work contains chemicals

known to cause cancer, birth defects or other reproductive harm. Some examples of these

chemicals are:

- Lead from lead-based paints,

- Crystalline silica from bricks and cement and other masonry products,

- Arsenic and chromium from chemically treated wood.

Your risk from this hazard varies with the frequency at which you perform this type of work. To reduce your

exposure to these chemicals: Work in a well-ventilated area. Work only with approved safety equipment,

such as dust masks that are specially designed to filter out particles of microscopic size.

Specific safety rules

Sawing method

- DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary

handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.

Fig. 3: Incorrect sawing vs. correct sawing

- Do not reach underneath the workpiece. The guard cannot protect you from the blade below the

workpiece.

- Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth

should be visible below the workpiece.

- Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a

stable platform. It is important to support the work properly to minimize body exposure, blade binding, or

loss of control.

- Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting

tool may contact hidden wiring or its own cord. Contact with a "live" wire will also make exposed metal

parts of the power tool "live" and could give the operator an electric shock.

- When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and

reduces the chance of blade binding.

- Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that

do not match the mounting hardware of the saw will run off-centre, causing loss of control.

- Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially

designed for your saw, for optimum performance and safety of operation.

MKS130Ec

Kickback - causes and related safety instructions

- Kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an uncontrolled saw

to lift up and out of the workpiece toward the operator;

- When the blade is pinched or jammed tightly by the kerf closing down, the blade stalls and the motor

reaction drives the unit rapidly back toward the operator;

- If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the

top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.

Fig. 4: Kickback of the machine

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided

by taking proper precautions as given below.

- Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces.

Position your body to either side of the blade, but not in line with the blade. Kickback could cause the

saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are

taken.

- When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the

saw motionless in the material until the blade comes to a complete stop. Never attempt to remove

the saw from the work or pull the saw backward while the blade is in motion or kickback may occur.

Investigate and take corrective actions to eliminate the cause of blade binding.

- When restarting a saw in the workpiece, centre the saw blade in the kerf so that the saw teeth are

not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as the

saw is restarted.

MKS130Ec

09/2022

- Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to sag

under their own weight. Supports must be placed under the panel on both sides, near the line of cut and

near the edge of the panel.

Fig. 5: Incorrect support vs. correct support

- Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing

excessive friction, blade binding and kickback.

- Blade depth and bevel adjusting locking levers must be tight and secure before making the cut. If

blade adjustment shifts while cutting, it may cause binding and kickback.

- Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut

objects that can cause kickback.

Function of the lower guard

- Check the lower guard for proper closing before each use. Do not operate the saw if the lower guard

does not move freely and close instantly. Never clamp or tie the lower guard into the open position.

If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting

handle and make sure it moves freely and does not touch the blade or any other part, in all angles and

depths of cut.

- Check the operation of the lower guard spring. If the guard and the spring are not operating

properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts,

gummy deposits, or a build-up of debris.

- The lower guard may be retracted manually only for special cuts such as "plunge cuts" and

"compound cuts". Raise the lower guard by the retracting handle and as soon as the blade enters

the material, the lower guard must be released. For all other sawing, the lower guard should operate

automatically.

- Always observe that the lower guard is covering the blade before placing the saw down on bench or

floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path.

Be aware of the time it takes for the blade to stop after switch is released.

MKS130Ec

09/2022

Function of the riving knife

- Use the appropriate saw blade for the riving knife. For the riving knife to function, the body of the blade

must be thinner than the riving knife and the cutting width of the blade must be wider than the thickness of

the riving knife.

- Adjust the riving knife as described in this instruction manual. Incorrect spacing, positioning and

alignment can make the riving knife ineffective in preventing kickback.

- Always use the riving knife except when plunge cutting. The riving knife must be replaced after plunge

cutting. The riving knife causes interference during plunge cutting and can create kickback.

- For the riving knife to work, it must be engaged in the workpiece. The riving knife is ineffective in

preventing kickback during short cuts.

- Do not operate the saw if the riving knife is bent Even a light interference can slow the closing rate of a

guard.
