MAINTENANCE
Before servicing or making adjustments to machine, stop engine and remove key from ignition.
Use all procedures and parts prescribed by the manufacturer's. Read the engine manual
before operation.
The suggested maintenance checklist is not offered as a replacement for the manufacturer’s but as a supple-
ment. You must adhere to guidelines established by manufacturer for warranty coverage. In adverse conditions
such as dirt, mud or extreme temperatures, maintenance should be more frequent.
LUBRICATION
Use No. 2 General purpose Lithium Base Grease and lubricate every 100 hours. The Supreme has three grease
fittings. One is located on the belt idler arm, one on the rod end of the steering cylinder and one on the rake lift.
Every 500 hours of operation, separate the hydrostatic pump from the engine. Clean the splined areas and lightly
grease the male portion of the pump spline. Use either Dow Corning

and that the pump is correctly aligned.
