Bevel Square to Table Adjustment
(Fig.A1, A2,I,L)
1. To align the blade square to the table, lock the arm in the down
position with the lock down pin
9
.
2. Place a square against the blade, ensuring the square is not on top of a
tooth (Fig. L).
3. Loosen the bevel lock knob
31
and ensure the arm is firmly against the
0° bevelstop.
4. Rotate the 0° bevel adjustment screw (
54
Fig. I) with the 6mm hex
blade wrench
29
as necessary so that the blade is at 0° bevel to
thetable.
Bevel Pointer Adjustment (Fig.I)
If the bevel pointers
48
do not indicate zero, loosen each screw
47
that
holds each bevel pointer in place and move them as necessary. Ensure the
0° bevel is correct and the bevel pointers are set before adjusting any other
bevel anglescrews.
Bevel Stop 45° Right and Left Adjustment (Fig.A2,I)
To adjust the right 45° bevel stop:
1. Loosen the bevel lock knob
31
and pull the 0° bevel stop override
32
to override the 0° bevelstop.
2. When the saw is fully to the right, if the bevel pointer
48
does not
indicate exactly 45°, turn the left 45° bevel adjustment screw
53
with
the 6 mm hex blade wrench
29
until the bevel pointer indicates45°.
To adjust the left 45° bevel stop:
a. Loosen the bevel lock knob and tilt the head to theleft.
b. If the bevel pointer does not indicate exactly 45°, turn the right 45°
bevel adjustment screw until the bevel pointer reads 45°.
Adjusting the Bevel Stop to 22.5° (or 30°) (Fig.A2, I)
NOTE: Adjust the bevel angles only after performing the 0° bevel angle and
bevel pointeradjustment.
To set the left 22.5° bevel angle, flip out the left 22.5° bevel pawl
51
.
Loosen the bevel lock knob
31
and tilt the head fully to the left. If the bevel
pointer
48
does not indicate exactly 22.5°, turn the crown adjustment
screw
49
contacting the pawl with a 10 mm wrench until the bevel pointer
reads 22.5°.
To adjust the right 22.5° bevel angle, flip out the right 22.5° bevel pawl.
Loosen the bevel lock knob and pull the 0° bevel stop
32
to override the 0°
bevel stop. When the saw is fully to the right, if the bevel pointer does not
indicate exactly 22.5°, turn the crown adjustment screw
49
contacting the
pawl with a 10 mm wrench until the bevel pointer indicates exactly 22.5°.
Fence Adjustment (Fig. A1)
The upper part of the fence can be adjusted to provide clearance, allowing
the saw to bevel to a full 49° both left andright.
1. To adjust each fence
11
, loosen the fence adjustment knob
10
and
slide the fenceoutward.
2. Make a dry run with the saw turned off and check forclearance.
3. Adjust the fence to be as close to the blade as practical to provide
maximum workpiece support, without interfering with arm up and
downmovement.
4. Tighten the fence adjustment knobsecurely.
5. When the bevel operations are complete, relocate thefence.
For certain cuts, it may be desirable to bring the fences closer to the blade.
To do so, loosen the fence adjustment knobs
10
and slide the fences
closer to the blade past the normal limit, then tighten the fence adjustment
knobs. Make a dry cut first to ensure the blade does not contact thefences.
For certain cuts it may be desirable to remove the sliding fence. To do so,
loosen the fence adjustment knobs
10
and slide the fence completely free
of the base fence. Once the cut is complete, replace the sliding fence.
NOTE: The tracks of the fences can become clogged with sawdust. Use a
brush or some low pressure air to clear the guidegrooves.
Guard Actuation and Visibility (Fig. X)
The lower guard
1
on your saw has been designed to automatically
uncover the blade when the arm is brought down and to cover the blade
when the arm israised.
The guard can be raised by hand when installing or removing saw blades
or for inspection of the saw. NEVER RAISE THE lower GUARD MANUALLY
UN LESS THE BLADE ISSTOPPED.
Rail Guide Adjustment (Fig. A1)
Regularly check the rails
7
for play orclearance.
The right rail can be adjusted with the set screw
5
. To reduce clearance,
use a 4 mm hex wrench and rotate the set screw clockwise gradually while
sliding the saw head back andforth.
Mitre Lock Adjustment (Fig. A1, M)
The mitre lock rod
55
should be adjusted if the table of the saw can be
moved when the mitre lock handle is locked (down).
1. Put the mitre lock handle
19
in the unlocked (up)position.
2. Using a 13 mm open end wrench, loosen the lock nut
56
on the mitre
lockrod.
3. Using a slotted screwdriver, tighten the mitre lock rod by turning it
clockwise as shown in FigureM. Turn the lock rod until it is snug, then
turn counterclockwise oneturn.
4. Re-lock the mitre lock to a non-detented measurement on the mitre
scale – for example, 34° – and make sure the table will notrotate.
5. Tighten locknut.
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.
