• Before work: Disconnect the power cable from the power supply.
NOTICE:
• Ensure that the arm is securely fixed when performing bevel cuts.
• Check that the blade does not touch the table at the rear of the slot or at
the front of the rotating arm at 90° vertical and 45° bevel positions.
• If the saw blade is worn, replace it with a new sharp blade.
• Check the technical data of the new blade: Use 216 mm saw blades with
30 mm arbor holes to obtain the desired cutting capacities.
• Replace the kerf plate when worn. If the kerf plate becomes worn or
damaged take saw to an authorised service centre.
Operating

Before use

• Check for damage to the tool and the power cable. Take care that
the power supply cord is not placed in the cutting area
• Check the upper blade guard, movable lower blade guard as well as
the dust extraction tube to determine that it will operate properly.
• Check the lower blade guard , it is designed to close quickly when
the lever is released. If it does not close within 1 second, have the
saw serviced by an authorized D
• Ensure that chips, dust or workpiece particle cannot lead to blockage
of one of the functions.
• In case of workpiece fragments jammed between saw blade and
guards disconnect the tool from the power supply. Remove the
jammed parts and reassembling the saw blade.
• Allow the blade to cut freely. Do not force.
• Always make dry runs (without power) before finish cuts so that you
can check the path of the blade.
• Allow the motor to reach full speed before cutting.
• Make sure all locking knobs and clamp handles are tight.

e
• As you move the saw arm left and right, follow it and stand
slightly to the side of the saw blade.
Cutting
• Always let the blade come to a full stop before raising the arm.
If small fibres of wood still split out at the rear of the workpiece,
stick a piece of masking tape on the wood where the cut will be
made. Saw through the tape and carefully remove tape when
finished.
• 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.
• When mitring the end of a piece of wood with a small off-cut,
position the wood to ensure that the off-cut is to the side of the
blade with the greater angle to the fence, i.e:
-
left mitre, off-cut to the right
- right mitre, off-cut to the left
After use
• Disconnect the power cable from the power supply.
• Store the Mitre Saw in a dry place and locked up securely, out of
reach of children.

NOTICE:
• Connect the saw to a dust collection device when sawing wood. Always
consider factors which influence exposure of dust such as:
ʵ good ventilation of the working place;
ʵ sharpness of the saw blade;
ʵ correct adjustment of the saw blade,
ʵ Push the saw through the workpiece. Do not pull the saw through
the workpiece.
