Extension cords:
If used, extension cords must be rated Hard Service (grade S) or better.
Conductor size must be 14 AWG for cords up to 50 feet in length. Your extension cord must also
contain a ground wire and plug pin. Always repair or replace extension cords it they become dam-
aged.
D. WORD OF CAUTION
In this section we have covered some basic electrical requirements for the safe operation of your
sander. As with the safety rules in the preceding section, these requirements are not necessarily
comprehensive. Further, you must be sure that your particular electrical configuration complies with
local and state codes. The best way to ensure compliance is to check with your local municipality or
licensed electrician.
Don’t take chances!
VIII. ADJUSTMENTS
All adjustments to your sander should be made with the power off and the machine unplugged.
A. BELT CHANGES
Belt life will be naturally extended by the oscillations of the belt since sanding will occur over a broad-
er section of the belt. To further extend belt life, clean them frequently with crepe rubber cleaners
such as Grizzly’s G1511 or G1512 Abrasive Belt Cleaners. See current catalog for more informa-
tion. When the belt does need replacement, follow the steps below:
1.
Remove the dust hood (#424, #432) by unscrewing the 2 lock knobs (#425) on the backside of
the hood.
2.
Unlock the quick-release lever (#303)
by pushing it toward “loose” on top of
the sander.
3.
Remove the old belt by lifting it straight
up from the rollers.
4.
Slide the new belt over the rollers, cen-
tering it as closely as possible and push
the quick-release toward “tight.”
5. Replace the dust hood.
B. BELT TRACKING
The belt on a properly tracked G1173 sander will oscillate up and down on the rollers. The lowest
and highest points that the belt reaches should remain constant under all sanding conditions. If you
find the belt to be tracking improperly (i.e.-steadily moving downward or upward), simply use the
tracking adjustment screwdriver to turn the tracking adjustment screw (#212) gradually in the direc-
tion that corrects for up or down movement.
