MACHINERY/EQUIPMENT CONNECTED TO HYDRAULICS
Be careful when you connect your machine or equipment to a hydraulic hose.
DANGER!
Pressurised oil and fuel leaks can penetrate skin and cause serious injuries. Do not use your
hands to locate leaks. Use a piece of paper or cardboard to look for leaks.
•
Warning for high pressure, risk of penetration injury.
•
Before repairs or maintenance are carried out, the system must be relieved of any
remaining pressure.
•
Switch off the tractor and move the hydraulic levers back and forth to release any
pressure that may still be in the oil hoses and pipes before starting any work on them
or the hydraulic cylinders.
•
Clean the filter in the suction pipe after 10 hours’ work.
•
Immediately replace hydraulic hoses if cracks or wear are detected.
•
Do not adjust the valve settings. Incorrect adjustment can result in damage to the machine
and/or injury.
•
The hydraulic system must only be operated using hydraulic oil intended for the purpose.
Check the oil level before you start the machine!
•
When commissioning a new machine, it is recommended that the hydraulic oil is changed
after the first 10 hours of operation, in order to remove any dirt or metal chips which may
have got into the hydraulic system.
NOTE: The oil becomes hot when it flows through the hydraulic system. Check the oil temperature at regular
intervals in order to avoid overheating. Stop the machine if the oil becomes overheated and allow the oil to
cool down.
As hydraulic systems are never 100% sealed, they must be inspected prior to loading
the equipment. Leaks can arise from internal leaks in tractor valves, electrical valves on
frontloaders, internal leaks in the equipment’s hydraulic cylinders, etc. Check the extent
of the leak by running the attachment’s cylinders at extreme position and maintaining
pressure for 1 minute. If the cylinder starts to ”drift” in the opposite direction, a gasket
is leaking. Replace gasket or cylinder.
