instructions.
4. Use control equipment carefully until the hydraulic oil has
had time to reach its operating temperature.
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 qualities
comply with applicable requirements. When replacing
or repairing hoses, use original parts or hoses and
connectors recommended by the manufacturer. 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 val-
ves, etc., are in place and work properly. Familiarize
yourself with their use. Safety systems may never be
bypassed.

as it can pollute waterways and the groundwater. If
biodegradable oil is to be used, contact the manu-
facturer beforehand and have the suitability of your
equipment for the operation 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, funnels,
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!
