Preparation for Service
The unit is lubricated, adjusted, and tested at the factory prior to shipment. It is then
prepared for shipment (See Section 4 of this chapter).
Before placing the unit in service, perform the commissioning
preparations. Failure to do so will cause the passenger stair to be unsafe to use,
operate, or service and could cause serious injury or death.
2.2 DAILY INSPECTION
Before putting the unit into service and each day before operating the unit, always walk
around the unit and make the following checks:
2.2.1
Hydraulic System
1.
Look for fluid leaks on the ground and on hydraulic components. Check
hydraulic hose and fitting connections for leaks and hose condition.
2.
Check level of hydraulic oil by observing the sight gauge on hydraulic
reservoir. The correct fluid is MOBIL DTE-13. In extreme cold, use Mobil
Aero HFA (MIL H-5606).
IMPORTANT! Check hydraulic oil level with
cylinders completely lowered or overfilling might result, causing damage
to the hydraulic system.
2.2.2
Stair Unit
1.
Check all critical fastener connections for security.
2.
Check that the stabilizer pads, links, and pivots are present and
functional and that the mounting hardware is secure.
3.
Remove any foreign objects from stairs and clean any grease, oil or other
lubricants from stairs.
4.
Check that the stair handrail is fastened securely to the stairs.
5.
Inspect the wheels at the lower edge of the platform handrails (wing
panels). If the wheels are cracked or damaged they must be replaced. Be
sure all fasteners and retaining brackets to keep the wheels on the guide
angle are in place and tight. Check that the notched track is tightly
attached to the panel.
6.
Check that the platform handrails (wings) slide freely. Check that the
latch works properly and that the handrails lock in the detents securely. If
the handrails do not slide freely or the latch does not work properly,
adjustment is required before the stair unit can be put into service.
