VARIABLE SPEED CONTROL
The Model 121 Oscillating Sander is
equipped with a variable speed control
dial (B) Fig. 4. The variable speed
control can be set on 1-6. The speed
ranges from 2400-3600 RPM, setting 1
is the slowest at 2400 RPM, and setting
6 is the fastest at 3600 RPM. The
oscillating spindle varies with the speed;
setting 1 is 2400 RPM with 38
oscillations per minute, setting 6 is 3600
RPM with 60 oscillations per minute.
EDGE GUIDE INSTALLATION
CAUTION: DISCONNECT TOOL
FROM POWER SOURCE.
NOTE: The edge guide should only
be used with the 2" rubber drum &
sanding sleeve.
The edge guide is used for sanding
straight edges for the purpose of
uniformity. The edge guide allows the
operator to remove a selected amount of
material.
Align the holes, in the base plate, (A)
and (B) Fig. 5, with the holes in the edge
guide, (C) and (D) Fig. 5, and insert the
two screws, and tighten securely.
Once the edge guide is in place, the feed
guides (A) and (B) Fig. 6 will need to be
adjusted so that they are parallel to the
sanding drum. Loosen the in-feed and
out-feed guides, (A) and (B), with a
3
/16"
allen wrench. Place a straight edge on the sanding drum (C) and tap the in-
feed and out-feed guides (A) and (B), until the feed guides and the sanding
drum (C) are resting on the straight edge Fig. 6, and are parallel to each
other. Tighten the
3
/16" bolt to hold
the out-feed guide (B) in place.
The in-feed guide (A) should be
set to the amount of material that
the operator wants to remove.
CAUTION: DO NOT TRY TO
REMOVE AN EXCESSIVE
AMOUNT OF MATERIAL
WITH THE TOOL, FOR IT
MAY CAUSE DAMAGE TO
THE RUBBER SANDING
DRUM.
