MAINTENANCE GUIDELINES
12 MONTHS (1,050 HOURS)
1. Inspect and lubricate PTO drive shaft to pump.
2. Take samples of hydraulic oil and test.
3. Check all system pressure adjustments for proper setting.
4. Replace hi-pressure filters.
5. Perform cylinder drift tests.
6. Clean pilot control inlet filters.
7. Perform structural and critical weld inspections.
8. Perform dielectric tests.
9. Perform leveling system inspections.
10. Daily, 30 days (120 hours), 90 days (360 hours), and 180 days (720 hours) inspections.
5 YEARS
1. Remove, disassemble and inspect leveling gearbox.
OPERATIONAL TESTS
Perform all of the tests and checks that follow. Cycle times must be within limits. Repair the problem that is
evident in the component.
SPEED TESTS
Speed tests should be taken with one man in platform and hydraulic fluid at normal operating temperature.
Check that all times are within the limits specified in the Quick Reference Guide.
1. Check that boom(s) operate smoothly over full travel, without squeaking or other noise.
2. Check that all moveable hydraulic and control hoses operate over full range of boom and turntable
movements without stretching, kinking or rubbing on sharp corners.
CONTROL SYSTEM
1. Check that all moveable hydraulic and control hoses operate over full range of boom and turntable
movements without stretching, kinking or rubbing on sharp corners.
2. Check that control handle returns to neutral when released from any position.
3. Check that all movements can be made to start smoothly, without jerking or sudden motion when control
handle is moved slowly.
4. Check that control head trigger energizes and de-energizes system so no movement of the booms
occurs if not actuated.
ELECTRICAL TESTS
Dielectric integrity of the booms must be tested every year or 1,050 hours of operation, whichever occurs
first, or if insulating components are replaced or if the insulation value is in question.
Follow electrical test specifications as prescribed by ANSI A92.2 for proper test procedure for the
classification of unit being tested. See Maintenance Manual for proper dielectric testing.
Platform insulation must never be depended upon when operating in an electrical
environment, and platform must be considered as having no insulation value
without a tested and certified liner installed.
