Checking the

hydraulic oil

level

A hydraulic oil level sightglass (a) is located on the hydraulic tank.

Check the oil level with the machine standing on a level surface. The oil level

should be at or near the MAX (a

) mark on the sightglass. If the hydraulic oil level is

low, add hydraulic oil as necessary.

If hydraulic oil continually needs to be added, inspect the hoses and connections

for possible leaks. Repair hydraulic leaks immediately to prevent damage to the

hydraulic components.

Changing the

hydraulic oil

and hydraulic

filter

Perform the procedure below to change the hydraulic oil and hydraulic filter.

1. Remove the drain plug (b) from the drain hose that is attached to the hydraulic

oil tank. Then, drain the oil into a suitable container.

Note: In the interests of the environment protection, place a plastic sheeting and a

container under the machine to collect the liquid which drains off. Dispose of

drained oil in accordance with the environmental protection legislation.

2. Re-install the drain plug after all the oil has drained out.

This procedure continues on the next page.
