tool off and disconnect tool from power source before making
any adjustments or removing/installing attachments or
accessories. Be sure the trigger switch is in the OFF position. An
accidental start-up can cause injury.
Ensure the machine is placed to satisfy your ergonomic conditions in terms
of table height and stability. The machine site shall be chosen so that the
operator has a good overview and enough free surrounding space around
the machine that allows handling of the workpiece without any restrictions.

bring the saw blade 7 close to the wood. The shadow of the blade will
appear on the wood.
2. Align the pencil line with the edge of the blade's shadow. You may
have to adjust the mitre or bevel angles in order to match the pencil
line exactly.
Speed Control Dial (Fig. A)
DWS771 only
The speed control dial 27 can be used for advance setting of the required
range of speed.
Turn the speed control dial 27 to the desired range, which is indicated by
a number (1–5).
• Use high speeds for sawing soft materials such as wood.
• Use low speeds for sawing hardwood.
Body and Hand Position (Fig. O)
Proper positioning of your body and hands when operating the mitre saw
will make cutting easier, more accurate and safer.

WARNING:
• Never place your hands near the cutting area.
• Place your hands no closer than 100 mm from the blade.
• Hold the workpiece tightly to the table and the fence when cutting.
Keep your hands in position until the switch has been released and
the blade has completely stopped.
• Always make dry runs (without power) before finish
cuts so that you can check the path of the blade.
• Do not cross your hands.
• Keep both feet firmly on the floor and maintain proper balance.
• As you move the saw arm left and right, follow it and stand slightly
to the side of the saw blade.
