10 GREASING
10.1
GENERAL
Before application of the grease remove old grease, clean up components with grease
solvent and apply new grease. Use grease specified by the producer.
Lifters of load capacity 2,5, 5 a 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.
Use grease: Universal lithium plastic lubricant, water resistant, usable in a minimum
range of working temperatures from -20°C to +50°C. For example A2, LV2EP.
! WARNING
All lubricants (grease, oil) used in the NEXP version must have an ignition temperature
higher than 135°C. E.g. LV2EP, ….
10.2
JACK
MECHANISM
Lubricate products with a load capacity of 2,5t, 5t and 10t with a lubrication press via a
lubrication plug on the cover.
Grease all slipping or moveable surfaces on the crank of the jack.
! NOTICE
Imperfect maintenance and insufficient greasing can cause serious accidents.
ALWAYS
grease it more often in corrosive environment (salt water, oceanic climate,
acids etc.) than in ordinary circumstances.
