Checking Bevel Lock Tension
1. Pull up the bevel lock lever to release tension.
If it feels too hard to pull up, an adjustment
may be required.
2. Check the tilt resistance. Grab main handle
and slowly tilt the saw to the left. While tilt-
ing, some resistance should be felt. At ap-
proximately 30°, the resistance should
become lower. If little or no resistance is felt,
an adjustment may be required.
3. Check bevel lock tension. Push down on the
bevel lock lever – normally more pressure is
needed at the start; then the lever should go
fully down to the lock position with a
"thump".
A) If it is too hard to push the lever fully down,
then it may require tension adjustment.
B) Check locking power: Tilt the saw to about
30° and push down on bevel lock lever. Firmly
press on the right side of the saw head - If the
saw head tilts more than 1/2° from the locked
position, then the bevel lock tension needs
adjustment.

Adjusting Bevel Lock Tension

The bevel lock lever tension has been set at the
factory. After extensive use of the tool, it may re-
quirean adjustment. Before adjusting tension,
the tilt resistance should be set.
1. Pull up the bevel lock lever to release tension.
2. Adjusting Tilt Resistance (see step 2 above).
A) If resistance is too low, slightly tighten
(1/16th turn) the large lock nut "H" using a
24mm socket or wrench.
B) If resistance is too high, slightly loosen
(1/16th turn) the large lock nut "H" using a
24mm socket or wrench.

Adjusting Bevel Lock Tension
3. Adjusting Tension (see steps 1 and 3
above) Pull up and push down the bevel
lock lever.
A) If the lever is too hard to pull or push, the
tension can be decreased by using a 17mm
socket or wrench to loosen lock nut "E"
(1/8th turn). Check again.
B) If the lever is too easy to pull or push or
if the saw head does not fully lock at a bevel
setting, then the tension can be increased
by using a 17mm socket or wrench to
tighten lock nut "E" (1/8th turn). Check
again.
