Safety instructions
When using Power Tools, always observe the safety regulations
applicable in your country to reduce the risk of fire, electric shock
and personal injury. Read the following safety instructions before
attempting to operate this product.
Keep these instructions in a safe place!
General
1 Keep work area clean
Cluttered areas and benches can cause accidents.
2 Consider work area environment
Do not expose Power Tools to humidity. Keep work area well lit. Do
not use Power Tools in the presence of inflammable liquids or gases.
3 Guard against electric shock
Prevent body contact with earthed surfaces (e.g. pipes, radiators,
cookers and refrigerators).
For use under extreme conditions (e.g. high humidity, when metal
swarf is being produced, etc.) electric safety can be improved by
inserting an isolating transformer or a (FI) earth-leakage circuit-breaker.
4 Keep children away
Do not let children come into contact with the tool or extension cord.
Supervision is required for those under 16 years of age.
5 Extension cords for outdoor use
When the tool is used outdoors, always use extension cords intended
for outdoor use and marked accordingly.
6 Store idle tools
When not in use, Power Tools must be stored in a dry place and
locked up securely, out of reach of children.
7 Dress properly
Do not wear loose clothing or jewellery. They can be caught in moving
parts. Preferably wear rubber gloves and non-slip footwear when
working outdoors. Wear protective hair covering to keep long hair out
of the way.
8 Wear safety goggles
Also use a face or dust mask in case the operations produce dust or
flying particles.
9 Beware of maximum sound pressure
Take appropriate measures for the protection of hearing if the sound
pressure of 85 dB(A) is exceeded.
10 Secure workpiece
Use clamps or a vice to hold the workpiece. It is safer and it frees both
hands to operate the tool.

before leaving it unattended. Unplug the tool when not in use,
before servicing or changing accessories.
15 Remove adjusting keys and wrenches
Always check that adjusting keys and wrenches are removed from the
tool before operating the tool.
16 Use appropriate tool
The intended use is laid down in this instruction manual. Do not force
small tools or attachments to do the job of a heavy-duty tool. The tool
will do the job better and safer at the rate for which it was intended.
Warning! The use of any accessory or attachment or performance of
any operation with this tool, other than those recommended in this
instruction manual may present a risk of personal injury.
17 Do not abuse cord
Never carry the tool by its cord or pull it to disconnect from the socket.
Keep the cord away from heat, oil and sharp edges.

operate properly and perform its intended function. Check for
misalignment and seizure of moving parts, breakage of parts and any
other conditions that may affect its operation. Have damaged guards

Additional safety rules for radial arm saws
• Protect the electric power supply with a suitable fuse or circuit breaker.
• Keep the bearing tracks in the arm and the bearings on the roller head
assembly clean and free from grease.
• Before switching ON, make sure that the fence is in the correct
position. The blade should not contact the material until the saw is
pulled by the handle.
• Always set the finger guard so that it passes through the pre-cut slot in
the fence and/or 3 mm above the surface of the material being cut
(except when ripping).
• When ripping, keep the riving knife adjusted to the correct distance
from the blade (1 - 3 mm) and make sure the kickback fingers are
properly adjusted.
• When ripping, always check the direction of feed.
• Regularly check the adjustments for accuracy and adjust as required.
• Make sure that the blade rotates in the correct direction and that the
teeth are pointing towards the fence.
• Make sure all clamp handles are tight before starting operation.
• Never run the machine without all guards in place.
• When not in use, protect the saw blade completely using the blade guard.
• When not in use, when changing blades or carrying out maintenance,
disconnect the machine from the power supply.
• Always use sharp blades of the correct type designed for the workpiece.
The recommended blade diameter is stated in the technical data.
• Do not wedge anything against the motor fan to hold the motor shaft.
• Do not force the cutting action. (Stalling or partial stalling of the motor
can cause major damage. Allow the motor to reach full speed before
cutting.)
• Do not lift the machine by its worktable.
• Do not cut ferrous metals, non-ferrous metals or masonry.
• Do not apply lubricants to the blade when it is running.
• Do not place either hand in the blade area when the saw is connected
to the power source.
• Do not reach around behind the saw blade when in use.
• Do not place hands closer than 150 mm from the saw blade while cutting.
• Do not use damaged or cracked saw blades.
