• Before transporting the saw, lower the saw head, loosen the rail lock
knob 17 and push the saw head all the way to the back. Press in the
lock down button 21 and tighten the rail lock knob.
• Lock the mitre arm in the full right mitre angle, slide the fence 15
completely inward and lock the fence lock knobs, then lock the bevel
clamp handle
18
with the saw head in the vertical position to make the
tool as compact as possible.
• Before transporting the saw, verify that the cord is disconnected.
• Always use the base extension handles
30 to carry the saw.
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 (Fig. A).
2. Press the saw head fully to the rear position and measure the height
from the rotating table 13 to the bottom of the outer flange 4 (Fig. F).
3. Loosen the rail lock knob 17 (Fig. B).
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 35 under the upper dust
extraction port 31 and adjust the screw 36 as required, proceeding
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 counterclockwise to loosen. Move the
sliding fence 15 to a position that avoids the blade cuts it,then tighten the
fence lock knob by turning clockwise.
Checking and Adjusting the Blade to the Fence
(Fig. B, I, J)
1. Slacken the mitre latch
12
.
2. Place your thumb on the mitre arm 11 and squeeze the mitre latch 12
to release the rotating table
13
/ mitre arm
11
.
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
38
on the mitre scale
14
are
just visible.
6. Place a square 40 (FIG. J) against the left side of the fence 15 and
blade 7 .
WARNING:
Do not touch the tips of the blade teeth with the square.
7. If adjustment is required, proceed as follows:
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 18 (Fig. L).
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 40 on the table and up against the blade 7 (Fig. K).
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 18 and turn the vertical position
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 43 that secure the scale and move the
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 is located in the left position.
2. Loosen the bevel clamp handle 18 by pulling it outward then down
and move the saw head to the left.
3. This is the 45° bevel position.
If adjustment is required, turn the stop screw 44 in or out as necessary until
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.
