OPERATING INSTRUCTIONS cont.
DANGER:
Failure to disconnect the supply cable
from machine whenever servicing, replacing abrasive, or emptying
the dust bag could result in electrocution or severe injury. Never
leave machine unattended while the supply cable is connected.
DANGER:
Never leave dust bag unattended with
sanding dust in it. Sanding dust can spontaneously ignite and cause
a fi re or explosion. Empty dust bag into a metal container, clear of
any combustibles. Do not empty content into a fi re. Do not overfi ll
dust bag.
ADJUSTMENT PROCEDURES
Leveling
To level machine: Grasp caster adjusting screw "A" with an appropriate
tool (pliers ect.). Using a similar tool, loosen locknut "B" with a counter
clockwise motion. (Figure 6).
Condition - Pad creates ridges on both edges or a "hop" is experienced:
Rotate both adjusting screws equal amounts clockwise. Tighten locknuts
and test on a piece of plywood. Repeat procedure until condition is cor-
rected. We recommend you not exceed 1/8" rotation for each attempt.
Condition - Pad creates a ridge on the tip of the pad: Rotate both adjust-
ing screws counter clockwise, tighten locknuts and test. Repeat proce-
dure until condition is corrected. Use only 1/8 rotation for each attempt.
Condition - Pad creates a ridge on only one side of the pad: Either rotate
the adjusting screw of the side effected clockwise or rotate theadjust-
ing screw opposite counterclockwise, depending on whether the ridge
terminates beyond the tip of the pad or prior to it. If it is prior to the tip,
adjust the side effected, otherwise adjust the opposite side.
ROUTINE MAINTENANCE
CAUTION:
Failure to perform maintenance at
recommended intervals may void warranty.
Carbon Brushes
Have the carbon brushes replaced at least every 500 hours and more
frequently under heavy use.
Dust Bag
Periodically the dust bag should be turned inside out, shaken vigor-
ously and machine washed in cold water
to prevent pore blockage and loss of dust control.
-10- FORM NO 70402B
Bearings
To insure reliable performance, have armature and pad driver
bearings inspected for wear or damage after every 1500
hours. If used heavily, have the bearings replaced seasonally.
Lubrication
The machine comes fully lubricated. The gears in the gear
box have enough lubrication for approximately six months of
normal operation. Have the lubricant changed at least every
6 months or more frequently under heavy use.
