INSTALLING DUST EXHAUST AND DUST BAG    
(FIG. E, F )

Sanding operations are inherently dusty. To help 
minimize the amount of dust that escapes into the 
surrounding air, this sander is equipped with a dust 
exhaust and dust bag. It is strongly recommended 
that users attach the dust exhaust and the dust bag 
when using this belt / disc sander.

 Use of a mask or 

respirator is still recommended even when a dust-
collection system is in use.

1.  Raise the belt bed (1) and secure in the vertical 

position.

2.  Loosen the inner hex screw (2) using the 5 mm hex 

key, attach the dust exhaust (3) on the dust port (4) 
of the sander, and tighten the inner hex screw (2).

Fig. E

3.  Insert the opening of dust bag (5) through the bag 

clamp (6), and release the clamp handle (7).

4.  Attach the the opening of dust bag (5) to the dust 

exhaust (3), slide the bag clamp (6) over the bag and 
exhaust and lock the bag clamp (6) to secure the 
dust bag (5).

Fig. F

NOTE: 

Turn the clamp handle (7) clockwise a full turn or 

two before locking to give a tight fit. Do not overtighten.

MOUNTING BELT / DISC SANDER TO WORKBENCH 
(FIG. H) 

If during operation there is any tendency for the 
sander to tip over, slide or walk on the supporting 
surface, it is recommended that you mount the 
sander on a flat and level workbench or stand 
to avoid any movement during operation. Four 
mounting holes are located on the base of the 
sander for this purpose.

1.  Place the sander on a surface that is level but also 

provides enough room on all sides for the workpiece 
and for the operator (or bystanders) to not be 
standing in line with the wood while using the tool. 
Allow room for the belt to be positioned horizontally 
or vertically.

2.  The hardware to mount this sander is NOT supplied 

with the sander.
