• Every season lubricate the auger bearings and the
bearings on the side of the frame with light oil. See to
Figure 16.
• Use oil or spray lubricant into the bearings at the
wheels at least once a season. Remove the wheels,

multi-purpose automotive grease.
• Lubricate the auger shaft at least once a season. To
do this:
• Remove the shear pins on the auger shaft.
• Oil or spray lubricant inside shaft.
• Carefully spin the auger around by hand to disperse
the lubricant.
• Reinstall the shear pins.
Wheel Drive Control / Auger Control Lock
The cams on the ends of the control rods which interlock

operation using a multi-purpose automotive grease. The
cams can be accessed beneath the handle panel. See
