Snorkel S3010E - Manual (Page 27)

Chapter 8 – Prestart Inspection
S3010E - 514226-000-ANSI 23
Caution
Not all hydraulic fluid is suitable to use in the hydrau-
lic system. Some have poor lubricating character-
istics and may increase component wear. Only use
hydraulic fluid as recommended.
2. If necessary, 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.
Hose, Tubes, and Fittings
To inspect the hose, tubes and fittings:
1. Inspect all hydraulic hose, tubes, and fittings for wear,
leakage, or damage (refer to Figure 8.7).
Figure 8.7 – Hose, Tubes, and Fittings
2. Make sure the hose is 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 the hose 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.
Cables and Wiring Harness
To inspect the cables and wiring harness:
1. Visually inspect all cables and wiring for wear and/or
physical damage such as loose connections, broken
wires, and frayed insulation.
2. Check the wiring in areas where a change in routing
direction may cause them to become pinched.
3. Make sure the cables and wires are properly routed
to avoid sharp edges, pinching, and scuffing.
Hydraulic System
Hydraulic power is supplied from a single stage hydraulic
pump with a 1.07 horsepower DC electric motor.
Danger
Hydraulic 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 immediately. In case of injury by escap-
ing hydraulic fluid, seek medical attention at once.
The hydraulic reservoir, pump, filter, and control valve are
located in the hydraulic tray on the left side of the chassis.
Fluid Level
To inspect the fluid level:
1. Make sure the aerial platform is fully stowed on a level
surface, remove cap and check the fluid level on the
dipstick is between the max and min level (refer to
Figure 8.6).
