To adjust hold-down clamp pressure and gap:
1.
Position upper blade at top dead center.
2.

To adjust hold-down clamp pressure, loosen
hex bolts to reduce pressure; tighten hex
bolts to increase pressure (see Figure 68).
Perform test cut and re-adjust bolts if needed.
IMPORTANT: Always adjust hex bolts evenly
in order to avoid possible damage to disc
spring stack.
4.
To adjust hold-down clamp gap, place sheet
stock under hold-down clamp, loosen hex
nuts at each end of clamp, then adjust set
screws until clearance is even on both ends.
Tighten hex nuts to secure gap setting.
CAUTION: DO NOT exceed
down clamp gap. A larger gap can reduce
clamp pressure and possibly damage
workpiece by marring surface if it slips dur-
ing cutting operation. When cutting thinner
material, reduce hold-down clamp gap and
perform Step 3.
5.
Re-install blade cover.

The Model G0845P is fitted with four V-belts that
transfer power between the motor and gearbox.
After initial break-in, the V-belts slightly stretch
and seat into the pulley. It is important to check
ON
and adjust them to compensate for this initial
OFF
wear. Check the tension thereafter on a monthly
basis. If one or more belts become excessively
worn or damaged, replace all four as a set.

Remove front cover.
Check belt tension. Each belt is correctly
tensioned when there is approximately
deflection when it is pushed with moderate
pressure, as shown in Figure 69.
