SAFETY INSTRUCTIONS 
FOR HYDRAULIC CIRCUITS

Work on hydraulic equipment may only be 
carried out by professional hydraulic engineers.
Be cautious when using the equipment in cold 
conditions.
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

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.
Check that all safety devices such as pressure 
relief valves, etc., are in place and work properly. 
Familiarize yourself with their use. 
Safety systems may never be bypassed.
Check the main hydraulic parts daily, and 
always after a fault.  Replace any damaged 
parts immediately.
If a component is damaged, clean it before 
repairing it. Do not use solvents when cleaning 
parts.
Do not attempt to carry out repairs that you are 
not fully familiar with.
Never carry out repairs of the hydraulic circuit 
when the system is pressurized. When 
pressurized, the oil spray can penetrate the skin 
and cause mortal danger.
Never work below a device or component that is 
only being held up by hydraulics. 
Use separate supports when carrying our 
maintenance or repairs.  Do not disconnect 
cylinders or their valves until the machine is well 
supported.
Most hydraulic oils do not evaporate easily. Risk 
factors include hot oil, spills and oil mist 
(pressurized).
If oil gets into your eyes, rinse with plenty of 
water and contact a doctor.
Avoid prolonged or repeated contact with your 
skin.

If sprays or contact with the skin cannot be 
avoided, use protective gloves, goggles and 
clothing as necessary. Do not use oily clothing.
Avoid discharging hydraulic oil into the 
environment, as it can pollute waterways and 
the groundwater. When working in ecologically 
vulnerable areas, use biofuel.
Store the oil in sealed containers provided by 
the manufacturer. Try to transfer the oil directly 
from its container into the tank.
If the oil must be passed through other containers, 
ensure that they are completely clean. Caps,

clean.
Never store oil outdoors, as water could condense 
in it.
Always dispose of oil in a suitable container, 
never into the environment!
