8 MAINTENANCE INSTRUCTIONS
This part of the Maintenance Instructions will walk you through the routine maintenance and the
necessary checks and adjustments.
8.1
SAFETY INSTRUCTIONS
*Disassembly of the crane or its parts, during the warranty period should be assigned to the manu-
facturer's authorized service person.
* During the maintenance, repair or cleaning, the boom has to be supported against the base! Do
not leave it pressured by hydraulics!
* The pump has to be disconnected and the engine to be switched off if the maintenance proce-
dure does not require the use of a crane.
*Opening, tightening, etc., of the pressurized hydraulic is prohibited.
* Caution should be exercised when removing hydraulic pipes and hoses ensuring that there is no
hydraulic pressure left in the line when the power source is turned off.
* When the hydraulic system is opened, air can access it, which can cause sudden, unpredictable
movements in deployment of the crane.
* Use adequate lifting capacity with the hoist and lifting aids handling the crane or its parts. Do not
stand under the weight during lifting or work.
* When working and servicing avoid skin contact with oil or lubricating greases. They contain sol-
vents and additives that in repeated contact with skin may be harmful (drying and cracking of skin).
Old dirty oil or grease is more dangerous than new. When processing of these materials, follow the
instructions given by the manufacturers and the authorities.
* If oil or lubrication grease have caused a skin rash, inflammation, or has come into contact with
the eyes, contact the doctor immediately.
* When handling oils and greases, use protection gloves, creams, glasses and clothing as needed.
* Do not use oily or greasy clothing and do not store oily objects in your pockets.
* Do not use lubrication oils or greases for cleaning your hands.
* The waste oil released during the maintenance or repair must be submitted for appropriate han-
dling.
8.2
GENERAL MAINTENANCE INSTRUCTIONS
First familiarize yourself with the maintenance instructions, because improperly or incompletely
performed maintenance can cause damage to the crane.
* The crane must be serviced periodically, to ensure safe and trouble-free operation.
Washing the electrical components with a pressure washer is
prohibited.
