4.3.3 Maintenance instructions for hydraulic system

WARNING

Do not use unskilled personnel for hydraulic system maintenance

Risk of injury and damage to property!

Take the following precautions:

❒ Only allow trained professionals to carry out servicing and maintenance work

on the hydraulic system. Follow the manufacturer's operating instructions.

NOTICE! Do not allow the oil temperature to exceed +50°C or fall below -30°C.

The interval at which oil should be changed depends on a variety of factors including

the age of the oil and the amount of dirt contained in it. As a general rule, the oil

should be changed at the following intervals:

Interval (service hours) Component / Maintenance Operation

50 - 100 First maintenance after installation. (This does not apply to subsequent mainte‐

nance):

❒

50 ❒ Check the oil level

➥ The oil must show no visible signs of foaming

❒

200 ❒ Check the return filter for dirt (pressure gauge on filter)

❒ Remove the unit cover or open the inspection cover

❒ Thoroughly clean the oil tank (make sure you remove all oil sludge)

❒ Change the return filter and the vent filter sets

❒ Refit the unit cover or close the inspection cover

❒ Fill the tank with hydraulic oil to the level mark shown on the inspection glass

☞ Use the hydraulic oil grade specified by the manufacturer

❒ At the other end of the cylinder plunger (relative to its current position), disconnect

the hydraulic cylinder hose on the fixed piping side. Place a container under the

disconnected hose.

❒ Using the hydraulic unit move the cylinders to the other end position

➥ The remaining old oil will be pushed out of the hose and into the container.

❒ Refit the hydraulic hoses and check the seal
