2. Open the door on the right side of the chassis to ac-
cess the hydraulic fluid level gauge (refer to Figure
7.9).
Figure 7.9 – Hydraulic Fluid Gauge
3. Make sure the fluid level is between the minimum
and maximum lines.
Caution
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.
4. If necessary, remove the filler cap and add fluid of
the proper type. Replace the cap making sure it is
tightly in place.
Note
Refer to Chapter 2 for the proper type and grade of
hydraulic fluid to use. The need to regularly add fluid
indicates a leak that should be corrected.
5. The sight glass on the reservoir has an internal
thermometer to measure the fluid temperature. The
temperature should be less than 200°F (93°C).
Fluid Filter
Checking the condition of the hydraulic fluid filter is part
of the machine maintenance schedule and should not
be performed by the operator.
Hoses, Tubes, and Fittings
To inspect the hoses, tubes and fittings:
1. Inspect all hydraulic hoses, tubes, and fittings for
wear, leakage, or damage (refer to Figure 7.10).
Figure 7.10 – Hoses, Tubes, and Fittings
2. Make sure the hoses are properly routed to avoid
sharp edges, kinking, and scuffing.
3. Inspect the tubes for dents or other damage that
may restrict fluid flow.
4. Make sure all hoses and tubes are held firmly in
their support brackets.
5. Check under the chassis for fluid that has leaked.
Hydraulic fluid leaks are easily visible on the
ground.
Tires and Wheels
Visually inspect the tires and wheels (refer to Figure
7.11) to make sure they are suitable for service.
Figure 7.11 – Tires and Wheels
Foam filled tires do not have a pressure decal or a
valve core.
To inspect foam filled tires and wheels:
1. Check the wheel lug nuts to see that none are miss-
ing, damaged, or loose.
