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.
