PROBLEM/SYMPTOM SOLUTION(S)
Litter will not lower with foot pedals depressed. Adjust valve control linkage rods (page 10).
Litter will not lift when foot pedal pumped. Add hydraulic fluid (page 7).
Bleed air from hydraulic system (page 7).
Change pump pedal cylinder(s).
Litter ”drifts”. Bleed air from hydraulic system (page 7).
Adjust valve control linkage (page 10).
Check for leaking hoses or fittings and replace.
Disconnect hose from affected jack, install cap on
fitting and watch for drift to determine if jack is
faulty.
If jack is O.K., replace check valve #6. If this does
not solve the problem, replace valve #1. If the litter
still drifts, replace valve #5 (see page 11 for valve
references).
Steer wheel doesn’t engage or disengage properly. Adjust steer wheel linkage (page 9).
Replace tension spring.
