A.2.5 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 couplings, rubbing of flexible hoses
against metal objects or components, 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 leaks of oil from the couplings may occur
due to the heat expansion caused by the high temperature of the hydraulic fluid. Tighten the
couplings using the torque settings suggested in the maintenance 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 becomes damaged switch OFF the machine immediately and identify the damaged area
using a piece of card 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 (authorised assistance centres
only) switch OFF the pressure to the hydraulic system and work away from hoses and steel lines.
