A.2.6 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.
- Switch OFF the supply to the system and release the residual pressure from the hydraulic circuit
before disconnecting any hoses.
- 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.

There is an electric shock hazard for the user under the following conditions:
•if the crane comes into contact with electricity power lines
•if the crane is struck by lightning
WARNINGS
- The crane should only be operated at a distance D of at least 7 m from electricity power lines. The
crane can be used closer to electricity power lines if, following notification to the electricity supply
company, suitable protection is adopted to prevent operation too close to the lines and accidental
contact. The minimum operating distance must be calculated on the basis of maximum crane
boom extension towards the lines and maximum movement of the lines.
D>7m
- The crane should only be used near live power lines if:
•Safety distances are adhered to
•Live parts are covered or surrounded by guards
