LUBRICATION

Do not use more than three pumps of
grease in a grease fitting at any one time.
Excess grease can cause grease seals to
fail, or allow grease into areas that could damage compo-
nents.
Putting more than three pumps of grease in a grease fitting
could damage grease seals and cause premature bearing fail-
ure.
Lubricate components at the intervals indicated in the SCHED-
ULED MAINTENANCE CHART on page 46.
