ADJUSTMENTS

WARNING: To reduce the risk of serious personal injury, turn
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.
Your mitre saw was accurately adjusted at the factory. If readjustment
due to shipping and handling or any other reason is required, follow the
steps below to adjust your saw. Once made, these adjustments should
remain accurate.
Adjusting the Rails for Constant Cutting Depth
(Fig. A, B, F, G)
The blade must run at a constant cutting depth along the full length of the
table and must not touch the fixed table at the rear of the slot or at the front
of the rotating arm. To achieve this, the rails must be perfectly parallel to the
table when the saw head is fully depressed.
1. Press the lower guard lock release lever
2. Press the saw head fully to the rear position and measure the height
from the rotating table to the bottom of the outer flange
13
3. Loosen the rail lock knob (Fig. B).
17
4. Keeping the saw head fully depressed, pull the head to the end of
its travel.
5. Measure the height indicated in Figure F again. Both values should
be identical.
6. If adjustment is required, proceed as follows (Fig. G):
a. Loosen the locknut 37 in the bracket
extraction port 31 and adjust the screw
in small steps.
b. Tighten the locknut 37 .

WARNING: Always 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. Do not switch on before having checked this!
Adjusting the Fence (Fig. H)
Turn the sliding fence lock knob 8
sliding fence 15 to a position that avoids the blade cuts it,then tighten the
fence lock knob by turning clockwise.

1. Slacken the mitre latch 12 .
2. Place your thumb on the mitre arm
to release the rotating table 13
3. Swing the mitre arm until the latch locates it at the 0° mitre position.
4. Pull down the head and lock it in this position using the lock down
button 21 .
5. Check that the two 0° markings
just visible.
6. Place a square (FIG. J) against the left side of the fence

a. Loosen the screws 39 and move the scale/mitre arm assembly
left or right until the blade is at 90° to the fence as measured with
the square.
b. Retighten the screws 39 .
Checking and Adjusting the Blade to the Table
(Fig. B, K–M)
1. Loosen the bevel clamp handle
2. Press the saw head to the right to ensure it is fully vertical and tighten
the bevel clamp handle.
3. Place a set square on the table and up against the blade
40

WARNING: Do not touch the tips of the blade teeth with the square.
4. If adjustment is required, proceed as follows:
a. Loosen the bevel clamp handle
adjustment stop screw 41 in or out with the hex wrench (as shown
in Fig. L) until the blade is at 90° to the table as measured with
the square.
b. If the bevel pointer 42 (Fig. M) does not indicate zero on the bevel
scale 19 , loosen the screws
scale as necessary.
Checking and Adjusting the Bevel Angle (Fig. L, M)
The bevel override allows the maximum bevel angle to be set at 45° or 48°
as required.
• Left = 45°
• Right = 48°
1. Make sure the override lever
29
2. Loosen the bevel clamp handle
and move the saw head to the left.
3. This is the 45° bevel position.
If adjustment is required, turn the stop screw
the pointer 42 indicates 45°.
Prior to Operation
• Install the base extensions to both sides of the saw's base. Refer to
Assembling the Base Extensions section.
• Check the protective belt cover for damage and the proper functioning
of the lower guard.
• Make sure to use the kerf plate. Do not operate the machine if the kerf
slot is wider than 12 mm.
• Install the appropriate saw blade. Do not use excessively worn blades.
The maximum rotation speed of the tool must not exceed that of the
saw blade.
• Make sure all locking knobs and clamp handles are tight.
• Use personal protective equipment and connect the saw to an external
dust extractor.
• Although this saw will cut wood and many nonferrous materials, these
operating instructions refer to the cutting of wood only. The same
guide-lines apply to the other materials. Do not cut ferrous (iron and
steel) materials, fibre cement or masonry with this saw!
• Do not attempt to cut excessively small pieces.
• Secure the workpiece.
• Allow the blade to cut freely. Do not force.
• Allow the motor to reach full speed before cutting.
