Chapter 11 - Maintenance
The machine operation is normal. Result: the diagnostics screen does not show code 18, no alarm goes off
and the driving and steering functions are normal. In this case, the exit protector limit switch must be
adjusted, or replaced.
4) Lower platform until it is folded down and remove wood block under right exit protector.
5) Repeat steps 31-34 under the left exit protector.
6) Lower the platform until it is retracted, then remove the log under the left exit guard.
7) Turn the machine off.
B-15 Inspection of upper limit switch
1) This check must be carried out every 250 hours or every quarter, whichever comes rst.
2) Good limit switch conditions are essential for performance and safe operation. The operation of the
machine with a defective limit switch will reduce the machine performance and lead to an possible unsafe
working environment.
3) Ensure that the functional inspection is carried out on a rm and level surface without any obstruction.
- Turn on the ignition switch on the ground control. Raise the platform to a height of about 3.2 m above the ground.
- Lift the safety support, move it to the centre of the scissors housing and turn it up until it is vertical.
• Lower the platform height until the safety support is completely against the shaft housing. Warning: risk of
crushing
Place your hand on the correct position of the safety support when lowering the platform.
• Open the limit switch base valve on the chassis.
• Raise the platform slightly and restore the safety support to the installation position.
• Raise the platform via the ground controls while pressing the upper limit switch arm to start the upper
limit switch. Result: the platform stops rising and the function of the machine is normal.
The result: the platform continues to rise. Replace or adjust the upper limit switch.
12.11 Steps of checklist C
C-1 Test of platform overload system
1) This step must be performed every 500 hours or every 5 months, whichever comes rst. Or the check must
be performed immediately when the overload error appears.
Calibration method No charge:
1:Turn the ignition switch to Platform mode; (note that the platform is at the very beginning)
2: Move the LIFT button as described below to activate the no-load automatic weighing procedure:
"DOWN" "DOWN" "DOWN" "DOWN" "DOWN" (5x) "UP" , "DOWN" "DOWN" "DOWN" "DOWN" "DOWN" (5x) "UP" ,
“DOWN,” “UP” “DOWN” “DOWN” “DOWN”
Pay attention:
a. Each operation of the button takes 0.15s - 2.5s;
b. The calibration is terminated when the control limit is reached. In this case, the
calibration performed again from the beginning.
c. After the klaxton sounds 5 times, this indicates that the calibration procedure has gone correctly.
