10.1 Cleaning and lubrication

For best results, make cleaning the sander a regular
shop procedure. Allowing excess build-up of dust and
debris can adversely affect performance through
loading of the abrasives, slippage on the conveyor
table, and/or the accumulation of material inside the
drums which can throw off the center of balance.
Leave the dust collector on when cleaning dust from
the drums. Also brush the conveyor belt after cleaning
operations. If not cleaned, the conveyor belt could
allow stock to slip during sanding operations.
NOTE: Bearings are pre-sealed and require no
lubrication.

Lubricate conveyor bushings as needed, and
check for wear.

Lubricate elevating leadscrew (A, Figure 10-1) as
needed.

Clean sawdust from abrasive strip and brush dust
from conveyor belt.

Keep slide areas clean (B, Figure 10-1).

Blow dust from motors and switches. Blow dust
from inside of sanding drum, which may cause
vibration or offset the center of balance.

Check all set screws for tightness on parts such as
bearings, conveyor table, and couplings.

machine under normal
maintenance ever become necessary, the drum has
been designed for easy removal and replacement.

10.3 Conveyor belt replacement

1. Disconnect sander from power.
2. Raise drum to highest position.
3. Turn take-up screws (Figure 8-2) on both sides of
conveyor to relieve belt tension, and slide the
driven roller fully inward.
4. Remove two (2) screws that attach conveyor table
to base.
5. Remove two (2) screws that attach conveyor table
to drum alignment bracket (E, Figure 10-3).
6. Loosen two locks (F, Figure 10-3).
7. Lift up conveyor table and remove it from
machine. Avoid tearing the belt on any edges
underneath the conveyor table. Do not allow the
Trackers to drop, as they may break.
8. Set conveyor on motor side and slide conveyor
belt off end of conveyor table.
9. Install new belt along with trackers (see sect.
11.0), and re-install conveyor table. Tension and
track the new belt.
Note: If conveyor belt continually tracks to one side of
the machine, reversing the belt on the conveyor table
may remedy the problem. To make sure the conveyor
table is not twisted, place a level on the conveyor
table. Level the machine if needed. If there is still a
problem, proceed with the steps below:
