PROCEDURE (Drawings 23635 & 23636)
See Drawing 23635 (Adjustment s)1. Set up the stair set with bolting faces of the landing vertical,like it will be when
installed on the truck.
2. With one of the cylinder pins removed, lower the stair to its' deployed position as seen in View 2 . Adjust the angle of inclination of the stair to 44 - 45Deg. to the horizontal. Adjust by grinding the stop pads on both stiles or by building the stop pads up with weld and then grinding. The bearing faces should be smooth and flat so as not to bite into the flange plate quickly, thereby losingthe adjustment. (This procedure should be repeated periodically during the service life of the stair set.) Views 2 & 3 .
3. Replace the cylinder pin and fully retract the cylinder. Ensure that the retracted cylinder allows the stair to decline to the angle set in ii above. If not, adjust the position of 23 675 Stair Actuator Attachment on the stair stile. View 2 .
4. By extending the cylinder, raise the stair to the vertical stowed position. View 1.
5. Adjust the position of the Stair Buffer Bracket 23 653 on the stair stile so that the buffer is compressed firmly when the stair is in the stowed position. View 1 .
6. Adjust the positions of the Handrail Bumpers 23 651 mounted to the stair stiles and handrail posts so they bear firmly on the handrails when the stair is stowed. These bumpers are there to prevent vibration and rattling. View 1 .
7. Adjust the position of the Go Switch Trigger 23 657 so the Go Switch creates the appropriate connection when the stair is raised, View 4 .
See Drawing 23636 (Bolting Pads)1. Per Views 1, 2 & 3 , attach the Bolting Pads to the bolt-on bumper extension at the
end of the central fixed bumper. Weld only to the extension.
2. Per View 4 , fit the assembled stair set to the bolting pads, without the Landing Deck or Landing Floor Infill fitted.
3. Per Views 5 and 6 , fit the Landing Floor Infill and then the Landing Deck.
NOTEFollow all on-site/Mine lif ting and safety procedures when inst allingPSFS to Truck.

Procedure
Remove centre console panel in cabin - - to do this remove six (6) screws and gear selection knob.
Position stairway indicator panel on centre console, above hour meter.- drill two mounting screw holes (6mm or 7/32")- one electrical cable hole (12mm or 15/32")- do not re-fix console Panel
Remove four (4) screws holding Komatsu fuse panel behind operator's seat. Drill one holeto insert Caterpillar fuse holder - fit fuse holder, into fuse indicator panel - tighten. Drillsize (12mm or 15/32").
Remove rear access panel from back of cabin and run short conduit through the maincable gland to inside centre console, ensuring conduit goes underneath control box.
Connect blue wire start from conduit above to blue wire of cabin indicator panel harness.
In rear access, connect black wire, with 10mm eye terminal to machine ground, and bluewire to outer terminal of newly inserted fuse holder.
Install short blue wire to screw terminal of Komatsu circuit breaker, and other end to fuseholder.
Run wiring harness from Power Step Folding Stairway magnetic proximity switch aroundunder radiator, and follow cabling/hose routing up to air line/ electrical outlet on rear RightHand Side of cabin.
Drill hole in RH Cabin access panel - route wiring harness in through access panel, andthrough to under centre console - connect wires appropriately as colour coded. Holesaw/drill size (24mm), cable tie harness as appropriate, approximately every 300mm.
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 LadderAscend 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 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.
