10 GREASING
10.1
GENERALLY
Before application of the grease remove old grease, clean up components with grease solvent
and apply new grease. Use grease specified by the producer, vaseline (lubricant grease)
PM-A2 or its equivalent.
Lifters of load capacity 5t and 10t are equipped with a lubrication plug on the cover of the gear
transfer. We recommend regular lubrication of the gear mechanism at least once every
6 months.
10.2
JACK
MECHANISM
Grease lifters of load capacity 5t and 10t by using the lubricant press through the lubricant plug
on the cover.
Grease all slipping or moveable surfaces on the crank of the jack.
! NOTICE
Imperfect maintenance and insufficient greasing can cause a serious accident.
ALWAYS
grease more often in corrosive environment (salt water, oceanic climate, acids
etc.) than in ordinary circumstances.
NEVER
grease the brake, the load fall can follow.
