GMK 4100L-1
Many defects and failures are caused by improper maintenance such as:
– Insufficient oil, grease or antifreeze,
– Dirt,
– Damage to the ropes,
– Faulty compressed air and hydraulic systems,
– Damaged hoses or loose screw connections,
– Faulty brakes,
– Faulty tyres or wheel rims,
– Exceeded maintenance intervals.
For your safety and the safety of others, avoid these errors by carrying out
maintenance work carefully within the specified intervals. Do not put off
maintenance work that is due. If repairs are needed, immediately contact
Manitowoc Crane Care
or an authorised GROVE dealer or your repair crew.
This work may only be carried out by trained, qualified personnel.
A few general maintenance instructions :
•
Clean the parts of the truck crane that are to be serviced, particularly the
area around the oil filler opening, the oil inspection opening, the oil drain
opening and the lubricating nipples.
•
When changing the oil, it should run out at operating temperature.
•
Ensure that only oils and lubricants specified in the
Lubricants
, p. 6 - 1
are used.
•
Replace all filters within the specified period if cleaning is not explicitly
permitted.
•
Always replace all gaskets before assembly. Clean the sealing surfaces.
•
Tighten loose screw connections on hydraulic and compressed
air systems only when the system is depressurised.
•
Keep brake and clutch linings free of grease.
•
Replace hydraulic hoses immediately once damage or moisture
penetration becomes visible.
•
Cleanliness is imperative when handling hydraulic oil. Even when
filling with fresh hydraulic oil, it must be filtered.
