Safety instructions

When using stationary power tools, always observe the safety
regulations applicable in your country to reduce the risk of fire,
electric shock and personal injury.
Read all of this manual carefully before operating the tool.
Save this manual for future reference.
General
1 Keep work area clean
Cluttered areas and benches can cause accidents.
2 Consider work area environment
Do not expose the tool to rain. Do not use the tool in damp or wet
conditions. Keep the work area well lit (250 - 300 Lux). Do not use the
tool where there is a risk of causing fire or explosion, e.g. in the
presence of flammable liquids and gases.
3 Keep children away
Do not allow children, visitors or animals to come near the work area or
to touch the tool or the mains cable.
4 Dress properly
Do not wear loose clothing or jewellery, as these can be caught in
moving parts. Wear protective hair covering to keep long hair out of the
way. When working outdoors, preferably wear suitable gloves and non-
slip footwear.
5 Personal protection
Always use safety glasses. Use a face or dust mask whenever the
operations may produce dust or flying particles. If these particles might
be considerably hot, also wear a heat-resistant apron. Wear ear
protection whenever the sound level seems uncomfortable, i.e. if the
sound pressure stated in this manual exceeds 85 dB(A).
6 Guard against electric shock
Prevent body contact with earthed or surfaces (e.g. pipes, radiators,
cookers and refrigerators). When using the tool 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.
7 Do not overreach
Keep proper footing and balance at all times.
8 Stay alert
Watch what you are doing. Use common sense. Do not operate the
tool when you are tired.
9 Secure workpiece
Use clamps or a vice to hold the workpiece. It is safer and it frees both
hands to operate the tool.
10 Connect dust extraction equipment
If devices are provided for the connection of dust extraction and
collection facilities, ensure that these are connected and properly used.
11 Remove adjusting keys and wrenches
Always check that adjusting keys and wrenches are removed from the
tool before operating the tool.
12 Extension cables
Before use, inspect the extension cable and replace if damaged.
When using the tool outdoors, only use extension cables intended for
outdoor use and marked accordingly.
13 Use appropriate tool
The intended use is described 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.
Do not force the tool.
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.
14 Check for damaged parts
Before use, carefully check the tool and mains cable for damage.

Check for misalignment and seizure of moving parts, breakage of parts,
damage to guards and switches and any other conditions that may
affect its operation. Ensure that the tool will operate properly and
perform its intended function. Do not use the tool if any part is
damaged or defective. Do not use the tool if the switch does not turn it
on and off. Have any damaged or defective parts replaced by an
authorised D WALT repair agent. Never attempt any repairs yourself.

15 Unplug tool
Switch off and wait for the tool to come to a complete standstill before
leaving it unattended. Unplug the tool when not in use, before changing
any parts of the tools, accessories or attachments and before
servicing.
16 Avoid unintentional starting
Be sure that the tool is switched off before plugging in.
17 Do not abuse cord
Never pull the cord to disconnect from the socket. Keep the cord away
from heat, oil and sharp edges.
18 Store idle tools
When not in use, tools must be stored in a dry place and locked up
securely, out of reach of children.
19 Maintain tools with care
Keep the tools in good condition and clean for better and safer
performance. Follow the instructions for maintenance and changing
accessories. Keep all handles and switches dry, clean and free from oil
and grease.

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.
