Maintenance
50
Inspect the Hydraulic Tank Cap
Venting System
This procedure should be performed every
250 hours or quarterly, whichever comes first.
A free-breathing hydraulic tank cap is
essential for good machine performance and
service life. A dirty or clogged cap may cause
the machine to perform poorly. Extremely dirty
conditions may require that the cap be
inspected more often.
1. Remove the breather cap from the
hydraulic tank.
2. Check for proper venting.
⊙
Result: Air passes through the breather
cap.
¤
Result: If air does not pass through the cap,
clean or replace the cap. Proceed to step 3.
Note: When checking for positive tank cap
venting, air should pass freely through the
cap.
3. Using a mild solvent, carefully wash the
cap venting system. Dry using low
pressure compressed air. Repeat step 2.
4. Install the breather cap onto the hydraulic
tank.
B-13
Check the Module Tray Latch
Components
This procedure should be performed every
250 hours or quarterly, whichever comes first.
Maintaining the module tray latch components
in good condition is essential to good
performance and service life. Failure to detect
worn out latch components may result in
module trays opening unexpectedly, creating
an unsafe operating condition.
1. Inspect each module tray rotary latch and
related components for wear. Tighten any
loose fasteners.
2. Lubricate each module tray rotary latch.
Using light oil, apply a few drops to each
of the springs and to the sides of the
rotary latch mechanism.
B-14
Test the Down Limit Switch, Level
Sensor and Pothole Limit Switches
This procedure should be performed every
250 hours or quarterly, whichever comes first.
Maintaining the limit switches is essential to
safe operation and good machine
performance. Operating the machine with a
faulty limit switch could result in reduced
machine performance and a potentially unsafe
operating condition.
Perform this procedure with the machine on a
firm, level surface that is free of obstructions.
Down limit switch
1. Remove the platform controls.
2. Raise the platform about 2.5m from the
ground.
3. Lift the safety arm, move it to the center of
the scissor arm and rotate down to a
vertical position.
4. Lower the platform onto the safety arm.
Crushing hazard.
Keep hands clear of the safety arm when
lowering the platform.
5. Turn the key switch to the off position.
6. Tag and disconnect the platform control
box at the platform.
7. Open the battery tray, tag and disconnect
the connector from the ECU to the
platform control cable.
8. Securely install the platform control box
harness plug into the connector of the
ECU.
9. Dismantle the cover of down limit switch,
tag and open the two wires in the switch.
10. Turn the key switch to platform control.
11. Raise the platform and return the safety
arm to the stowed position.
