TILT STOP ADJUSTMENT
Using a combination square, check the 90 degree
(zero) and 45 degree stops as shown in Figure 14.
Adjust stop positions if required, using the stop screws
as shown. Check the accuracy of the pointer at 90
degrees (zero) and readjust if required.
MITRE GAUGE ADJUSTMENT
1. Slide the mitre gauge into one of the slots on the
table top.
2. The gauge is equipped with individually adjust-
able index stops at 90 degrees and 45 degrees right
and left. The index stops can be adjusted by tighten-
ing or loosening the three adjusting screws (A) as
shown in Figure 15.
3. To operate the mitre gauge, loosen lock handle
(B) and move the body of the mitre gauge (C) to the
desired angle. The mitre gauge body is set to stop at
90 degrees and 45 degrees left or right. To move the
gauge beyond these points, the stop rod (D), must be
pulled out.
4. If accurate crosscutting work is to be done using
the mitre gauge, check its squareness to the slot with
a machinists square as shown in Figure 15. Readjust
the stop position as required.
BELT TENSIONING
The saw is equipped with a set of three matched belts.
If they should need replacement, replace the complete
set.
1. To remove the belts, loosen the hex screw (A)
and hex nut (B) and rotate the motor and bracket to
the left as far as possible. Remove one belt at a time.
2. Install the new belts. Tension them by pivoting
the motor bracket to the right. Re-tighten screw (A)
and nut (B).
NOTE: Proper tension is achieved when the part of
the belt midway between the sheaves can be deflected
approximately 1/8" to 1/4" using moderate finger pres-
sure.
