LUBRICATION
ENGINE
Check the engine oil level daily. Change the
engine oil after every 25 hours of operation. Use a
straight SAE 30-weight, API class SF engine oil. If
multiviscosity oil is used, oil consumption and
combustion deposits will increase.
Using other than service class SF oil or extending
oil change intervals could cause engine damage
not covered by the engine warranty.
The engine oil capacity is 1 qt (0.95 L).
DRIVE CHAINS
The two wheel drive chains propel the machine.
They should be lubricated with a penetrating-type
spray lubricant after every 100 hours of operation.
