2. Install the new saw blade onto the shoulder provided on the inner
flange
33
making sure that the teeth at the bottom edge of the blade
are pointing towards the fence (away from the operator).
3. Replace the outer flange
4
, making sure that the location lugs
34
are
engaged correctly, one on each side of the motorshaft.
4. Tighten the blade bolt

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 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 up 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. Turn the saw head 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
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.

WARNING: The guide grooves can become clogged with sawdust. Use
a stick or some low pressure air to clear the guidegrooves.
Checking and Adjusting the Blade to the Fence
(Fig.A, 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/mitre arm
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
pin
21
Fig. B.
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
(Fig. I) 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
39
.
Checking and Adjusting the Blade to the Table
(Fig.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 until the blade is at 90° to the
table as measured with thesquare.
b. If the bevel pointer
42
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.A,L,M)
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
29
(Fig. L) is located in the leftposition.
2. Loosen the bevel clamp handle
18
and move the saw head to theleft.
3. This is the 45° bevelposition.
4. If adjustment is required, turn the stopscrew
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
guidelines 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.
