Lubrication
Make sure that grease fittings are cleaned off before
filling grease. Dirt on the fitting that is not cleaned off
is pushed into the part with the new grease. Always fill
grease to the point where old grease and contaminants
are forced out from the part and only new grease comes
out. If grease can not be filled so old grease is forced
out or if new grease exits without pushing old grease out,
note this on the form for repair. If a fitting does not accept
lubrication due to damage or internal stoppage, replace
with a new fitting.
Do not heat part for better grease application where
rubber or plastic parts are involved.
Remove excess grease from fittings, spring shackles and
other surfaces.
