Trailer Lubrication - PRONAR PT512 Operator's Manual

CHAPTER 5

5.6 TRAILER LUBRICATION

Trailer lubrication should be performed by means of manually or foot operated grease gun
filled with recommended grease. Before commencing lubrication remove old grease and
other contamination as far as possible. After finishing remove excess of grease.
Parts which should be lubricated with machine oil, should be wiped with dry clean cloth and
then a small quantity of oil should be applied on surfaces (with oil can or brush). Wipe off
excess of oil.
Change of grease in axle hub bearings should be entrusted to specialized service points
equipped with the appropriate tools. According to recommendations of the axle manufacturer,
dismantle the entire hub, remove bearings and individual sealing rings. After careful washing
and inspection, mount lubricated elements. If necessary, bearing and seals should be
replaced with new parts. Lubrication of axle bearings shall be performed at least once in
2 years or every 50,000 km. In case of intensive use, lubrication should be performed more
frequently.
Empty grease or oil containers should be disposed according to recommendations of the
lubricant manufacturer.
