Section 1 Installation and Mounting Instructions


WARNINGRaising the POWER STEP platform by external means can create a vacuum in thehydraulic cylinder and create the opportunity to allow air into the hydraulic system,defeating the inherent safety features of the POWER STEP.This must be avoided, to maintain safe operation of the POWER STEP.

In instances where the use of external means to raise the platform must be used, please follow the following instructions:

Loosen hard plumbed hydraulic lines on cylinder side of lock valve on cylinder.Raise platform by available means.Note: Make necessary arrangements to collect displaced oil, and be aware that air entersthe piston side of the cylinder as platform is raised.Lock in raised position.Re-tighten hydraulic fittings.SECURE THE PLATFORM IN THE RAISED POSITION, MECHANICALLY, CHAIN &TAGOUT THE POWER STEP

To recommission the POWER STEP:

Loosen hydraulic fittings on cylinder side of lock valve.Note: Collect displaced oil.Lower platform to lowest position, using alternate safety approved means, fully retractingcylinder. Ensure all personnel are clear of step radius.Operate electrical control switch to purge air from the hydraulic line systems, lock valveand cylinder.Tighten the hydraulic fittings either side of lock valves to restriction fittings.Cycle step unloaded several times to purge all air from hydraulic system.The Power Step will not operate correctly if there is any air in the hydraulic circuit (due tothe incorrect operation of the lock valve).

NOTE.THE RELIEF PRESSURE OF THE POWERPACK IS TO BE SET TO 2800PSI.IF THE POWERPACK IS REPLACED,THIS RELIEF PRESSURE WILL NEED TO BERESET USING INLINE GAUGES.FAILURE TO DO SO MAY RESULT IN ACCIDENT OR INJURY.


Section 2 Recommended Maintenance Procedure

DailyVisually check st airway and structure for damage, loose component s, handrails, etc.

Check for hydraulic oil leaks from hydraulic cylinders, plumbing and hoses.

Notify the appropriate supervisor for any observed damage or malfunction.

500 HoursGrease 2 grease nipples on hinge pinsCheck main mounting bolts for torque.

Check hydraulic oil level in power pack and top up as necessary. (Stairway in raisedposition).

Top up using SAE46 or SAE68 hydraulic oil.Thoroughly check all electrical wiring for damage, replace as necessary.

Repeat daily check as above

5000 HoursChange hydraulic oil in tank of hydraulic power pack (5.0 litres)

It is recommended that SAE46 or SAE68 hydraulic oil be used in the power pack.

Check and inspect all main bolts on stairway system.Retorque if required.

Repeat daily check as above



Section 3 Operating Procedure

To Lower S tairway (from the machine)Position machine in a level, safe area, away from the work face, whenever possible.Apply park brake and lower engine speed to idle.Check that the area below the Ladder Access System is clear of people and obstacles, and lower ladder by operating the two position electrical switch adjacent to the ladder, to the down position by pressing the switch down.Hold the switch in the down position until ladder is fully lowered.If the truck is parked on uneven ground, the bottom of the stairway may touch the ground before the ladder is in the fully lowered position.Should this occur, descend the ladder with caution.

To Raise S tairwayAscend the ladder onto the landing of the Loader.Ensure the area around the ladder is clear of people and standing to the side, clear of the area the handrails and ladder raises into, operate the electrical switch to the raise position (up).Hold the switch in the up position until the ladder is in the fully raised position.The ladder is now raised and stored.


OPERATING NOTES

NOTE: FLOW CONTROL VALVE ADJUSTMENT:The valve should be positioned to restrict the flow and speed of the Power Step whenlowering. Adjust the knob on top of the valve by turning left or right (clockwise) when thestep is being lowered, until it is lowering at a safe and reasonable speed.

When it is adjusted, lock the adjusting knob by tightening the grub screw located on theside of the knob.

NOTE: MAGNETIC 'GO' SWITCH ADJUSTMENT:The switch target trigger area is located on the opposite side and end from the cable entrypoint on the switch. Once it is mounted to the switch bracket, adjust the switch in or outfrom the stair steel trigger point, to be within 3mm - 10mm from touching each other whenthe stair is in the desired rest position.[DO NOT EXCEED 10mm DISTANCE BETWEEN THE SWITCH AND STRIKER PLATE].Test by raising and lowering the Power Step a couple of times and adjust again ifnecessary.
