Motor mount tracking adjustment
Referring to Figure 11:
This machine comes with tracking adjustment
bolts (A) on the motor plate. These are set at the facto-
ry and should not require any further adjustment. If,
however, you are not able to track the belt with the
Belt Tracking Adjustment described in the previous
section, the motor mount bolts will have to be adju-
sted.
NOTE: The motor mount tracking adjustment is a
course adjustment. Use the Belt Tracking Adjustment
first for fine adjustment. If it cannot be adjusted, then
use the procedure described below.
To adjust:
1. Disconnect the machine from the power source.
2. Slightly loosen the four motor mount nuts (B) just
enough so the tracking screws (A) can be turned to
make an adjustment.
3. Loosen the two locking hex nuts (C) that secure the
tracking screws (A).
4. Turn one screw (A) a 1/4 turn and rotate the sanding
belt by hand to observe which direction the adjustment
is causing the belt to move. If it is traveling in the di-
rection needed to correctly track the belt go to step 6.
5. If the belt starts to travel in the wrong direction,
back off a quarter turn and tighten the other screw a
quarter turn. This should start the belt moving in the
proper direction.
6. Tighten both locking nuts (C) and motor mount nuts
(B). Then return to the Belt Tracking Adjustment sec-
tion (previous page) and again attempt to fine tune the
tracking.
Table adjustment
WARNING! Do not position table below sanding
belt! Keep an overlap of at least 1/16" between ta-
ble and sanding belt to avoid material and/or fingers
getting caught! Failure to comply may cause serious
injury!
1. Loosen two lock knobs (A, Fig. 12).
2. Raise or lower work table to desired level.
3. Tighten two lock knobs.

6. BASIC OPERATIONS

WARNING! Removing the belt guard exposes more
of the sanding belt! Replace the belt guards immedi-
ately after completing any sanding that requires its
removal! Failure to comply may cause serious injury!
