HYDRAULIC SYSTEM
7.3
A. CHECkING HYDRAULIC OIL LEvEL
The hydraulic oil level should be checked after the first 10
hours of operation. Thereafter, check the oil after every
200 hours of machine operation or monthly, whichever
occurs first.
- IMPORTANT -
If the oil level is consistently low, check for leaks
and correct immediately.
Wipe dirt and contaminants from around the
1.
hydraulic level indicator window.
Visually check the level of hydraulic oil. Hydraulic
2.
oil must be within the center of the wide postion of
the indicator window when the machine is cold. See
Figure 7-2. If the fluid is low, add 20W50 motor oil.
DO NOT overfill; (overfilling the oil reservoir may
cause oil seepage around the cap area).

B. CHANGING HYDRAULIC OIL AND FILTER
The hydraulic system oil should be changed after the first
120 hours of machine operation and every 400 hours or
annually thereafter, whichever occurs first. The oil should
also be changed if the color of the fluid has become
black or milky. A black color and/or a rancid odor usually
indicates possible overheating of the oil, and a milky color
usually indicates water in the hydraulic oil.
