Hydr
aulic fluid escaping under pressure can have enough force to inject fluid into the
flesh. Serious infection or reaction will result if medical treatment is not given
immediatley. In the event of injury from escaping hydraulic fluid, seek medical
attention at once.
The hydraulic reservoir, pump, and filter are located in the hydraulic tray on the left side of the chassis.
Open the cover to inspect the hydraulic components.
FLUID LEVEL
To inspect the fluid level:
1. Make sure the aerial platform is fully stowed on a level surface. Open the hydraulic tray cover and
visually check the fluid level using the hydraulic level indicator attached to the hydraulic tank (refer
to Figure 2-7). Some machines may have a fill cap with a dipstick. The fluid must be visible on the
dipstick.
Figure 2-7 –
Hydraulic Tank
Not all hydraulic fluid is suitable to use in the hy-
draulic system. Some have poor lubricating char-
acteristics and may increase component wear.
Only use hydraulic fluid as
recommended.

2. If necessary, add fluid of the proper type.
Note
Refer to specifications on page 2-32 for the proper type and grade of hydraulic fluid to use. The need
to regularly add fluid indicates a leak that should be corrected.
3. Replace the cap making sure it is secured in place.
