direction. This will usually get the cable to lie in
the drum properly.
If the cable has become badly tangled, which
shouldn't occur if used properly, it may be nec-
essary to pull the entire cable out of the drum
and reinstall it. (See "How to Install Cable" sec-
tion.)

drum connecting cable already attached to the
drum.
2. Remove the V-Belt.
3. Turn the drum
clockwise with one
hand while push-
ing the cable into the

4. Be certain that the cable goes into the drum
in a clockwise direction as you look at the front
of the machine, or the cable will tangle in the
drum.
5. Replace the V Belt after cable is installed.
NOTE: The cable should lay in the drum in a
clockwise direction.
HOW TO REMOVE DRUM
1. Remove belt guard by loosening the knob

the cable end.
4. Unscrew knob behind the front post and pull
the Power Cable Feed off of the machine.
5. With one hand on the

6. Unscrew the ringbolt in the center of the
drum and slide the drum off of the drum shaft
and lift it out of the way.

MAINTENANCE

IMPORTANT: DISCONNECT MACHINE FROM
POWER SOURCE BEFORE PERFORMING MAINTE-
NANCE!
To keep your machine operating smoothly, it is
essential that all bearings be lubricated. Oiling
Fig. 1
moving parts is particularly important where
machine comes in contact with sand, grit and
other abrasive material.
CABLE MAINTENANCE
To get maximum service from your cables, be
sure that they are clean and well oiled. This not
only provides running lubrication but greatly
extends the life of the cables as well. Some users
periodically pour oil directly into the drum.
Then, as the drum turns, the cables get com-
plete lubrication.
FEED MAINTENANCE
Keep feed free of excessive soil and grit. It is rec-
ommended that the feed be flushed with fresh
water followed by a light oiling of the moving
parts. No disassembly is normally required. Fail-
