SECTION 4: ASSEMBLY
Securing Motor
to Bench
The sanding motor body must be securely mount-
ed before the machine can be safely used.
There are four
3
⁄
" holes in the motor base which
8
can be used to secure the machine to a tool stand
or workbench. Figure 2 shows the approximate
dimensions of the hole pattern. It is best to use
the actual motor base as a guide for positioning
the holes.
The Sander can be temporarily mounted by using
bolts with wing nuts. The Sander must be secure-
ly mounted because sanding forces can be signif-
icant and could cause the sanding machine to
move.

Attaching Flap Sander
The Flap Sander attachment is secured with a
couple of ties which hold the assembly together
when it is not mounted on the motor shaft.
Carefully release the ties and remove them. Hold
the assembly together by grasping both end
plates at the same time.
The Flap Sander attachment is designed to be
mounted on the left hand spindle of the motor
(when facing the front of the motor, the side with
the switch on it). The mounting bolt has a left
handed thread on it which can only be properly
installed on the left hand spindle.
The abrasive side of the sanding flaps should face
the operator when mounted on the machine. Slide
the assembly onto the motor spindle, then thread
the bolt with the flange washer onto the end.
Figure 3 shows the proper mounting direction of
the Flap Sander and the installation of the retain-
ing nut on the end of the spindle.
