lithium base grease or molybdenum base grease, after every
8 hours of operation or daily, whichever comes first.
Lubricate fittings immediately after every washing,
regardless of the interval listed.

must be lubricated. The lubrication points are: castor
shaft bushings (2) and fan shaft bearings (2) (Fig. 17).

Servicing Bumper Bushings

After many hours of operation, the bushings pressed into

bushings, move castor fork fore and aft and from side to
side. If castor spindle is loose in the bushings, bushings are
worn and must be replaced.
1. Start traction unit and raise blower to highest possible
position and turn off engine. Block up blower frame so
it cannot accidentally fall.
2. Remove locking cap and thrust washers from top of
castor spindle.
