GMK truck cranes
Suspension struts – check oil level
Spare parts and
tools
– Press with connected hose (from tool box)
Prerequisites – The engine is not running and is secured against unauthorised use.
– Immediately before the inspection, the truck crane was completely
lowered and returned to On-road level; àOperating Instructions.
Checking the
oil level
Use only oil as specified in the maintenance plan M1; àp. 1.
•Check whether oil is visible in the middle of
the inspection glass (1) on each suspension
strut.
If the oil level is too low:
•Open the connection (2) – oil escapes – and
quickly connect the press with hose.
•Inject oil up the centre of the inspection
glass.
•Remove the hose and quickly close the
connection (2).
SRisk of damage due to faulty suspension struts
If the oil level is above the upper marking on the inspection glass the
suspension strut is faulty and must be replaced.
Notify an authorised GROVE dealer or CraneCARE.
SRisk of damage to the suspension struts due to insufficient lubrication
It is difficult to inject the oil. Even so, do not fill oil through the inspection
glass connections. If you do this, the oil will not reach all the lubricating
points.
