  Operating instructions 

11.1

  Starting and stopping sander 

The on/off switch (see Figure 8) is mounted in a 
switch box on right side of sander base. Move 
switch to forward (ON) position to start sander. 
Move switch to rear (OFF) position to stop sander. 

 

Figure 8: On/Off switch 

11.2

  Locking switch in OFF position 

We recommend that switch be locked in OFF 
position when sander is not in use. The switch can 
be locked by pulling the switch locking tab out of 
the switch toggle (see Figure 9). The switch will not 
operate with locking tab removed. If switch toggle 
is removed when sander is running, it can be 
turned OFF once, but it cannot be restarted without 
inserting switch tab.

  Typical operations 

The following are just some of the many operations 
that can be performed with your JET Sander: 

Sharpening a wood chisel on the sanding belt 
using a block of wood. Use the block of wood to 
support the chisel and provide clearance for the 
chisel handle (see Figure 25). 

 

Figure 25:  Sharpening a wood chisel 

Sand a bevel in the block of wood in order to 
position the wood as close as possible to the 
sanding belt and clamp the wood to the table, as 
shown. A cold chisel can also be sharpened on the 
belt table with the table tilted. 

Sanding aluminum on the disc unit with the table 
tilted and using the miter gauge as a guide (see 
Figure 26). 

NOTE:

 Always sand on the left (downward) side of 

the sanding disc, as shown. Sanding on the right 
(upward) side of the sanding disc could cause the 
workpiece to fly up which could be hazardous.
