MAINTENANCE

LUBRICATE AUGER GEAR BOX

The auger gear box is lubricated at the factory and should not require
additional lubrication. If for some reason the lubricant should leak out,
or if the auger gear box has been serviced, add Lubriplate GR132 Grease or
equivalent. Maximum 3- 1/4 ounces, (92 grams) should be used.
Remove filler plug (A A , Figure 15), once a year. If grease is visible, do not
add. If grease is not visible, use a piece of fine wire, like a dipstick to check
if there is grease in the gear box. Mobilux EP1 and Shell Alvania EP1 are
suitable equivalents.

LUBRICATE AUGER SHAFT FITTINGS

1. Using a hand grease gun, lubricate the auger shaft fittings (B B , Figure
15) every ten (10) operating hours. Each time a shear pin is replaced,
the auger shaft (C C ) MUST be greased. (See "Auger Shear Pin Replace-
ment" section.)
2. For storage or when replacing shear pins, remove shear pins and
lubricate auger shaft fittings (B B ). Rotate augers several times on the
shaft and reinstall the shear pins.

CHECK/LUBRICATE FREE-HAND LINKAGE

Check the function of the Free-Hand controls. The controls should function
as described in the OPERATION section.
WARNING: It is critical for the safe operation of the
unit that the controls disengage when released.
If the controls do not function properly, l l ubricate the controls (see
Figure 16).
NOTICE: Under no circumstances should the unit be used if the
controls do not function properly.

LUBRICATE CHUTE ROTATION GEAR

Lubricate the chute rotation gear (A A , Figure 17) and shaft (B B ) with automo-
tive type oil every twenty-five (25) operating hours .
ADJUST THE DRAG ON THE CHUTE ROTATION
NOTE: After repeated use, the chute rotation gear may loosen,
causing the chute to move back to the center position.
Adjust the drag by tightening the nut (C C , Figure 17). Tightening the nut will
limit the chute from moving without the operator turning the chute rotation
crank.
