Pressure Roller Test
It is absolutely essential to keep the pres-
sure rollers set below the level of the sand-
ing roller. If the pressure 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 kick-back injury.
To check the pressure roller height:
1. DISCONNECT THE SANDER FROM THE
POWER SOURCE!
2. Place a piece of scrap wood of uniform
thickness across the table so it spans both
the front and the rear pressure rollers at the
same time.
3. With the air pressure connected and the
sanding belt installed and tensioned, manu-
ally raise the table and verify that the board
touches both pressure rollers before it touch-
es the sanding belt.
Note: If the board does not touch both pres-
sure rollers before it touches the sanding belt,
then the pressure rollers must be adjusted
before operation. Refer to
Pressure Rollers
on
Page 33.
The pressure rollers have been set at the factory,
but for your safety, you should verify that they are
set below the level of the sanding roller.
