Lubrication

Greasing the Bearings,
Bushings and Pivots

Service Interval:

Every 50 hours

Lubricate all grease fittings for the bearings and bushings
with No. 2 General Purpose Lithium Base Grease.
Lubricate bearings and bushings

immediately

after

every washing, regardless of the interval listed.

Replace any grease zerks that become damaged.

Grease all cutterhead grease points and ensure that
sufficient grease is injected such that clean grease is seen
to escape from the roller end caps. This provides visible
evidence that the roller seals have been purged of grass
debris etc. and will ensure maximum working life.

The grease fitting locations and quantities are as follows:
