Application of lighting
When checking fuel, oil, coolant or battery electrolyte, always
use lighting with anti-explosion specifications.
High-pressure hoses

You may not bend high-pressure hoses or hit them with hard
objects. Do not use piping or hoses with tears or bends,
because they may burst during operation.

Replace loose or damaged fuel or oil hoses immediately.
Leaking fuel or oil is a potential slipping hazard and is flam-
mable.

Replace hoses every 2 years at the latest.
Handling high pressure oil

Always keep in mind that the hydraulic circuits are under
high pressure.

Do not add or remove oil and perform maintenance or
inspection work, before the work equipments has been com-
pletely lowered and the system is depressurised.

If oil escapes under high pressure, there is a danger of oil
entering the skin or eyes. Therefore always wear safety gog-
gles and thick gloves and use a piece of cardboard or wood
to search for oil leakages.

If you are hit by a stream of high pressure oil, immediately
consult a doctor for medical attention and explain the inci-
dent.
