ADJUSTMENTS

WARNING: To reduce the risk of serious personal injury, turn
machine off and disconnect battery pack before making any
adjustments or removing/installing attachments or accessories.
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 Traverse Bars for Constant Cutting
Depth (Fig. A, B, F, H)
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 traverse arms must be perfectly
parallel to the table when the saw head is fullydepressed.
1. Press the lower guard lock up release lever
2
(Fig.A).
2. Press the saw head fully to the rear position and measure the height
from the rotating table
14
to the bottom of the outer flange
5
(Fig.F).
3. Turn the saw head traverse lock
18
(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.H):
a. Loosen the locknut
37
in the bracket
38
and adjust the screw
39
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. I)
Turn the sliding fence lock knob
9
anti-clockwise to loosen. Move the
sliding fence
16
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, J, K)
1. Slacken the mitre latch
13
.
2. Place your thumb on the mitre arm
12
and squeeze the mitre latch
13
to release the rotating table/mitre arm
14
.
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
22
.
5. Check that the two 0° markings
40
on the mitre scale
15
are
justvisible.
6. Place a square
41
against the left side of the fence
16
and blade
8
.

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
42
and move the scale/mitre arm assembly left
or right until the blade is at 90° to the fence as measured with the
square (Fig.J).
b. Retighten the screws
42
.
Checking and Adjusting the Blade to the Table
(Fig. L–N)
1. Loosen the bevel clamp handle
19
(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
41
on the table and up against the blade
8
(Fig.M).

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
19
and turn the vertical position
adjustment stop screw
43
in or out until the blade is at 90° to the
table as measured with thesquare.
b. If the bevel pointer
44
does not indicate zero on the bevel scale
20
,
loosen the screws
45
that secure the scale and move the scale
asnecessary.
Checking and Adjusting the Bevel Angle (Fig. A, L, N)
The bevel override allows the max. bevel angle to be set at 45° or 48°
asrequired.
• Left = 45°
• Right = 48°
1. Make sure the override knob
46
is located in the leftposition.
2. Loosen the bevel clamp handle
19
and move the saw head to theleft.
3. This is the 45° bevelposition.
4. If adjustment is required, turn the stopscrew
47
in or out as necessary
until the pointer
44
indicates 45°.

WARNING: The guide grooves can become clogged with sawdust. Use
a stick or some low pressure air to clear the guidegrooves.
Prior to Operation

WARNING:
• Install the appropriate saw blade. Do not use excessively worn
blades. The maximum rotation speed of the tool must not exceed
that of thesawblade.
• Do not attempt to cut excessively smallpieces.
• Allow the blade to cut freely. Do notforce.
• Allow the motor to reach full speed beforecutting.
• Make sure all locking knobs and clamp handles aretight.
• Secure theworkpiece.
• Although this saw will cut wood and many nonferrous
materials,these operating instructions refer to the cutting of wood
only. The sameguide-lines apply to the other materials. Do not cut
ferrous (iron and steel) materials or masonry with this saw! Do not
use any abrasivediscs!
• Make sure to use the kerf plate. Do not operate the machine if the
kerf slot is wider than 10mm.
• Placing the workpiece on a piece of wood will increase the
capacities to 300mm.
