SAFETY INSTRUCTIONS FOR HYDRAULIC CIRCUITS
1. Work on hydraulic equipment may only be carried
out by professional hydraulic engineers.
2. Be cautious when using the equipment in cold
conditions.
3. Check the machine for leaks. Do not use the
machine if there is a leak from any system. Check
all hydraulic hoses – particularly those which are
bent during use – and replace any that are in poor
condition or have leaks. Ensure that all joins are
tight and that the lines are not damaged. Check
that all protective caps and ller caps are closed
properly. Check the hose sheathing for damage.
4. Check that all hose connectors, lengths and quali-
ties comply with applicable requirements. When
replacing or repairing hoses, use original parts or
hoses and connectors recommended by the ma-
nufacturer. Check particularly that the pressure
classes of the hoses and connectors are suitable to
the operating pressure levels.
5. Check that all safety devices such as pressure relief
valves, etc., are in place and work properly. Fami-
liarize yourself with their use. Safety systems may
never be bypassed.
6. Check the main hydraulic parts daily, and always
after a fault. Replace any damaged parts imme-
diately.
7. If a component is damaged, clean it before
repairing it. Do not use solvents when cleaning
parts.
8. Do not attempt to carry out repairs that you are
not fully familiar with.
9. Never carry out repairs of the hydraulic circuit
when the system is pressurized. When pressuri-
zed, the oil spray can penetrate the skin and cause
mortal danger.
10. Never work below a device or component that is
only being held up by hydraulics. Use separate
supports when carrying our maintenance or re-
pairs. Do not disconnect cylinders or their valves
until the machine is well supported.
11. Most hydraulic oils do not evaporate easily. Risk
factors include hot oil, spills and oil mist (pressu-
rized).
12. If oil gets into your eyes, rinse with plenty of water
and contact a doctor.
13. Avoid prolonged or repeated contact with your
skin.
14. If sprays or contact with the skin cannot be
avoided, use protective gloves, goggles and
clothing as necessary. Do not use oily clothing.
15. Avoid discharging hydraulic oil into the
environment, as it can pollute waterways and the
groundwater. If biodegradable oil is to be used,
please contact the manufacturer beforehand and
have the suitability of your equipment for the ope-
ration with biodegradable oil conrmed by him
before such oil is used.
16. Store the oil in sealed containers provided by the
manufacturer. Try to transfer the oil directly from
its container into the tank.
17. If the oil must be passed through other containers,
ensure that they are completely clean. Caps, fun-
nels, sieves and lling holes must also be clean.
18. Never store oil outdoors, as water could condense
in it.
19. Always dispose of oil in a suitable container, never
into the environment!
