-16- G9983 15" Open-End Wide-Belt Sander
Pressure Rollers
Always keep the pressure rollers set below
the level of the sanding roller. If the pres-
sure rollers are even, or higher than the
sanding roller, the wood WILL be propelled
from the sander at a high rate of speed.
This situation could cause serious person-
al injury.
The pressure rollers have been set at the factory,
but for increased personal safety, you should ver-
ify that they are below the sanding belt.
To check the feed pressure:
1. Disconnect the sander from the power
source!
2. Place a piece of scrap wood of uniform thick-
ness across the conveyor so it spans both
front and rear pressure rollers at the same
time.
3. Make sure the platen is even with the sand-
ing belt rollers.
4. With the air pressure connected, the sanding
belt installed, and the belt tension switch ON,
slowly raise the conveyor and verify that the
board touches both pressure rollers before it
touches the sanding belt.
If the board does not touch both pressure
rollers before it touches the sanding belt,
then the pressure rollers must be adjust-
ed before operation. See Section 8:
Service Adjustments for step-by-step
instructions on how to do this.
Sanding Belt Tension
Figure 12. This is the belt tension switch.
The sanding belt tension is controlled by a switch
located inside the upper portion of the machine
(see Figure 12). To locate it, open the access
door on the left-hand side of the sander.
To Tighten Belt Tension:
Flip the switch up. The vertical cylinder will auto-
matically tighten the top roller to the correct ten-
sion.
To Loosen Belt Tension:
Flip the switch down. The vertical cylinder will
automatically loosen the belt tension for belt
removal.
NOTICE
The belt tension switch is part of the air
control system. This means the machine
must have air pressure for the switch to
work correctly.
NOTICE
Always tighten belt before starting sander!
