OIL LEAK HAZARD
Hydraulic fluid leaks can cause burns, irritation to the skin and eyes and can even penetrate under
the skin.
These hazards are associated with incorrect tightening of fittings, rubbing of hoses against metal
parts, excessive bending of hoses, incorrect disconnection of hoses during maintenance, incorrect
repairs, ageing, etc.
WARNINGS
- When the crane is new and used for the first time, small oil leaks from the fittings may occur due
to the heat expansion. Tighten the fittings using the torques given in this manual. Couplings may
be damaged if they are too tight.
- The crane is designed in such a way to prevent rubbing of hoses against moving parts. However
the installation configuration may cause hoses to come into contact with other moving parts. If this
happens use additional sheaths to protect the hoses.
- If a hose is damaged, immediately switch OFF the machine and identify the damaged area using
a piece of cardboard or wood. Spurts of fluid from a very small hole are powerful enough to
penetrate the skin.
- Precautions shall be taken when disconnecting hydraulic tubing and hoses to ensure that no
hydraulic pressure is retained in the line when the power supply to the system is switched OFF.
- When using blowtorches and other welding equipment for repairs (at an authorised assistance
centres only) switch OFF the pressure to the hydraulic system and work away from hoses and
steel lines.
