Sanding Workpiece; Platen Adjustment - Grizzly H2933 Instruction Manual

Sanding Workpiece

Typically, no more than 0.5mm (approx.
material is removed during each pass. Attempts
to remove too much material can cause jamming,
wood burning, rapid paper wear or tearing, poor
finish, short motor life, and belt slippage.
The following is the correct sanding operating
procedure:
1. Put on safety glasses, a dust mask, and
hearing your protection!
2. Turn ON the dust collector.
3.
On the initial pass, set the table to approxi-
mately 0.25" greater than the thickness of
the workpiece.
Note:
This initial pass setting reduces the
chance of overloading the sander on
tected high points on the workpiece.
4. Continue to raise the table 0.0625" between
each successive pass until the sander begins
to sand the workpiece.
NOTICE
It may be necessary to send wide stock
through the sander two or three times
between table height adjustments. This
reduces the likelihood of burning the wood
if there is a high spot.

The three basic platen positions:
Platen Up: The platen is raised above the level
of the sanding rollers. This position allows the
front roller to remove large amounts of material
quickly, but leaves a rough finish. The best belt
grit for this position is #100 or coarser.
Platen Even: The platen is set even with the
sanding rollers. The rollers work together with the
platen to produce intermediate/final finishing. The
best belt grit for this position is #100-#180.
Platen Down: The platen is lowered below
the sanding rollers. The majority of the work is
accomplished by the platen pressure on the work-
piece. The result is a smooth, flat finish. The best
belt grit for this position is #180 or finer. Avoid
lowering the platen more than 0.2 mm below the
sanding belt rollers, or you will prematurely wear
the platen.
Note: The platen scale is broken down in millime-
ter increments.
