The hydraulic reservoir, pump, filter, and control valve are
located in the hydraulic tray on the right side of the chas-
sis.
Fluid Level
Check the hydraulic fluid level with the aerial platform on
a level surface and the platform stowed. The fluid level
must be between the add and full marks (refer to Figure
8.6).

Caution
Not all hydraulic fluid is suitable to use in the hy-
draulic system. Some have poor lubricating char-
acteristics and can increase component wear. Only
use hydraulic fluid as recommended.
If necessary, remove the filler cap and add fluid of the
proper type. Refer to Chapter 2 – Specifications for the
proper type and grade of hydraulic fluid to use. The need
to regularly add fluid indicates a leak that should be cor-
rected.
Hoses, Tubes, and Fittings
Inspect all hydraulic hoses, tubes, and fittings for wear,
leakage, or damage (refer to Figure 8.7). Make sure the
hoses are properly routed to avoid sharp edges, kinking,
and scuffing. Inspect the tubes for dents or other damage
that may restrict fluid flow. Make sure all hoses and tubes
are held firmly in their support brackets.
Hydraulic fluid leaks are easily visible on the ground.
Check under the chassis for fluid that has leaked.

Free-Wheeling Valve
The free-wheeling valve is located on the hydraulic mani-
fold (refer to Figure 8.8) on the hydraulic tray. Check the
free-wheeling valve to make sure it is fully closed (clock-
wise).

Tires and Wheels
Visually inspect the tires (refer to Figure 8.9). They should
be smooth without any cuts, gouges, or missing rubber
that might affect aerial platform stability.
