spindle speed. Spindle speed for all belt positions
are listed in Table 2 below.

source.
2. Open the door of the cabinet.
3. Remove the belt tension by moving the belt
tension handle (A) to the unlock position. This
allows the motor (G) to swivel on its mounting
hinge.
4. Move the drive belt (shown in the B position)
to the C, D, or E positions for the spindle
speed desired as determined in Table 2.
5. Lock the belt tension handle (A) which
secures the motor (G) and places tension on
the drive belt (K).

Drive Belt Tension
Referring to Figure 16:
The drive belt should have sufficient tension to
prevent slippage when the machine is in
operation. If the tension on the belt needs
adjustment:
1. Disconnect the machine from the power
source.
2. Open the door of the cabinet.
3. Locate the belt tension assembly (F) and
loosen the lock nut (H, inset) with a 17mm
wrench.
4. Adjust the hex bushing (J) with a 17mm
wrench (refer to inset for adjustment
direction) for proper tension on the
belt (B).
The tension handle (A) must be in the locked
position (right) while performing this step.
Note: Two 17mm wrenches are required for the
next step.
5. Maintain the position of the hex bushing (J)
with one wrench while tightening the lock
nut (H) with the other.
