11.0 LUBRICATION AND MAINTENANCE
11.1 General Maintenance Information
Perform each lubrication and service illustrated in this section at the beginning and end of each sea-
son.
IMPORTANT:
The period for recommended lubrication and maintenance is based on normal condi-
tions. Severe or unusual conditions may require more frequent lubrication or oil changes.
IMPORTANT:
The items listed separately from the lubrication chart and the servicing interval pages
are of extra importance. These items must be well maintained and checked routinely to maximize
their lifespan.
11.1.1 Grease:
SAE multipurpose high temperature/extreme pressure grease with less than 1% mo-
lybdenum disulfide grease should be used.
Clean grease fittings before using a grease gun. Replace any lost or broken fittings immediately. If a
new fitting fails to take grease, remove it and check for failure of adjoining parts.
11.2 U Joints
IMPORTANT:
On needle bearings (A), use of grease with more than 1%
molybdenum disulfide content may lead to premature U joint failure.
11.3 Hydraulic Oil Tank Level
The hydraulic oil tank should be filled so that 2 inches (5.1
cm) of oil shows above the low level line.
NOTE:
Check the oil level every 10 hours. Change oil and
filter annually.
