Pg3PSA-D475A-F/L-FULL 9-10-15
PROCEDURE
See 23625 - Bolting Pads:
1. Weld components 23 607 01, 02 & 03 to the machine as shown in this drawing.
See 23626 - Platform:
1. Fit the Isolator Housings and Rear Isolator Brackets (fitted together as assemblies)
to the bolting pads on the back of the machine per View X and Detail W.
2. Fit the Rear Spreader Beam across the two assemblies in 'i' above per View X and
Detail W.
3. Fit Isolators to the bolting pad per View Y and Detail U.
4. Fit the Side Platform with all its' auxilary components so as to be supported by the
Rear Spreader Beam at the back and the Isolators at the front, per Views Y & Z
and Details U, V & W.
See 30264 - PROP:
1. Fit Clamp Beams and Clamps to the heavy roof plate of the ROPS, per Details Y &
Z.
2. Hold/clamp the Carrier Bars, already assembled with the PROP and Isolators to the
Clamp Beams so the PROP is central with the stowed ladder, per Detail Y. Tack
weld the Carrier Bars to the Clamp Beams.
3. Adjust the outer end of the PROP so it engages the ladder between the two top
treads (top in stowed position) by fitting/moving Isolator Spacers. Adjust the position
of the PROP so the ladder bears against it firmly when fully raised, by changing
which boltholes are used for the isolator pins.
4. Fully weld the Carrier Bars to the Clamp Beams, per Detail T.
NOTE
Follow all on-site/Mine lifting and safety procedures when installing
Power Step Landings to Dozer.

Maintenance Notes
Pg14PSA-D475A-F/L-FULL 9-10-15
NOTE
Follow all on-site/Mine lifting and safety procedures when installing
Power Step Landings to Dozer.
WARNINGRaising the POWER STEP Landing by external means can create a vacuum in the
hydraulic 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 landing must be used,
please follow the following instructions:
Loosen hard plumbed hydraulic lines on cylinder side of lock valve on cylinder.
Raise landing by available means.
Note: Make necessary arrangements to collect displaced oil, and be aware that air enters
the piston side of the cylinder as landing is raised.
Lock in raised position.
Re-tighten hydraulic fittings.
SECURE THE LANDING 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 landing to lowest position, using alternate safety approved means, fully retracting
cylinder. Ensure all personnel are clear of step radius.
Operate electrical control switch to purge air from the hydraulic line systems, lock valve
and cylinder.
Tighten the hydraulic fittings either side of lock valve to restriction fitting.
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 to
the incorrect operation of the lock valve).

WIRING HARNESS 1
Daily
Visually check ladder and structure for damage, loose components,
handrails, etc.
Check for hydraulic oil leaks from hydraulic cylinders, plumbing and hoses.
Notify the appropriate supervisor for any observed damage or malfunction.
500 Hours
Grease the nipples on the rotation shaft and sector gears.
Check main mounting bolts for torque.
Check hydraulic oil level in power pack and top up as necessary. (Ladder in raised
position).
Top up using same hydraulic oil as used in hydraulics of machine.
Thoroughly check all electrical wiring for damage, replace as necessary.
Repeat daily check as above
5000 Hours
Change hydraulic oil in tank of hydraulic power pack (5.0 litres)
It is recommended that the same hydraulic oil be used in the power pack as the
hydraulics of the machine.
Grease 4 grease nipples on rotation shaft and sector gears, all of these are
accessible with the ladder lowered, and accessed from under the ladder.
Check and inspect all main bolts on ladder system.
Retorque if required.
Repeat daily check as above

Section 3. Recommended Maintenance Procedure
Pg21PSA-D475A-F/L-FULL 9-10-15
NOTE.THE RELIEF PRESSURE OF THE POWERPACK IS TO BE SET TO 2800PSI.
IF THE POWERPACK IS REPLACED,THIS RELIEF PRESSURE WILL NEED TO BE
RESET USING INLINE GAUGES.
FAILURE TO DO SO MAY RESULT IN ACCIDENT OR INJURY.
HYDRAULIC LADDER + WALKWAYKomatsu D475A
Section 4. Operating Procedure
Pg22PSA-D475A-F/L-FULL 9-10-15
To Lower Ladder (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 Dozer is parked on uneven ground, the bottom of the ladder may touch the
ground before the ladder is in the fully lowered position.
Should this occur, descend the ladder with caution.
To Raise Ladder
Ascend the ladder onto the landing of the Dozer.
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 when
lowering. Adjust the knob on top of the valve by turning left or right (clockwise) when the
step 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 the
side of the knob.
NOTE: MAGNETIC 'GO' SWITCH ADJUSTMENT:
The switch target trigger area is located on the opposite side and end from the cable entry
point on the switch. Once it is mounted to the switch bracket, adjust the switch in or out
from the stair steel trigger point, to be within 3mm - 10mm from touching each other when
the 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 if
necessary.
