Extension Cords
If an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the machine's motor plate. An undersize cord
will cause a drop in line voltage resulting in loss
of power and overheating.
The chart in Figure 20 shows the correct size
cord to use based on cord length and motor
plate amp rating. If in doubt, use the next
heavier gauge. The smaller the gauge number,
the heavier the cord.
Adjustments
Switch Lockout
Unauthorized use of the sander can be
prevented by pulling out the key (Figure 21).
Press switch to OFF position before removing
the key. When the key is removed, the drum can
not be started. (Note, however, that the
conveyor belt can still run when the key is
removed).
To replace the key, slide it back into the switch
until it snaps.
Dust Cover
To access the drum, lift the front of the dust
cover using the handle and push back the front
cover all the way to secure it in open position.
The dust port should be on the back or outfeed
side of the sander.
When removing the dust cover for initial drum
alignment or other reasons, lift the front cover
half-way and pull the dust cover out from the
outfeed side of sander. The edges will pop out
when the dust cover is pulled from the carriage
leg brackets. Reverse this procedure to re-install
the dust cover.
The dust cover should not require removal for
fine tuning alignments or for changing or
cleaning the abrasives.
Table Height Control
NOTE: Read “Table Support Screws”, page 9,
before operating the handwheel.
The table height and depth of cut are controlled
by the height adjustment handwheel (see Figure
6). Rotating the handwheel raises or lowers both
sides of the table simultaneously by transferring
the handwheel rotation through the miter gear
and transfer rod assembly.
Check the operation of the height adjustment
mechanism. If it does not operate smoothly or
easily, check the following:
