MAINTENANCE
1) Use a good grade of hydraulic jack oil. Never mix different types of fluid.
2) Store the crane in the retracted position to protect the ram from dirt and water which will eventually cause
rust and could damage the internal seals.
3) Moving parts should be lubricated once a month using a general purpose grease.
4) Hydraulic repairs should be performed by a qualified hydraulic technician.
AIR PURGE
Sometimes air will get trapped in the hydraulic system during transportation or normal operation, to purge air
from the jack, perform the following steps:
1) Open the release valve by turning it counterclockwise two full turns.
2) Pump the handle 12 full strokes.
3) Close the release valve by turning it clockwise until tight (do not overtighten).
4) Pump the jack until the ram is extended to its maximum height.
5) If air is still present, repeat steps 1 through 4.
