MAINTENANCE
1. Park the machine on flat, level and firm ground. Lu-
bricate the bearings and sliding slots.
2. Use ground controller to lift and lower the platform
without loading twice; the platform must operate in
its normal state.
3. Lower the platform until the scissor arm is in the
fully retracted state. Gradually add a load to the
platform.
The test results appear in Table 4-7 , page 4-12 :

Name Test Result
GTJZ0612E
When the weight does not exceed 550 kg (1213 lb), ensure that the platform is able to lift to the
highest position.
When the platform load is greater than or equal to 660 kg (1455 lb), if the platform lifting height
is greater than 1 m(3.3 ft) or 10% of the height that can be lifted (use the greater number), sev-
eral things will happen. The overload indicator lamp will illuminate, an alarm will sound, and the
work platform will not be able to move. Once you remove the excess weight, the work platform
will be able to move again.
GTJZ0812E
When the weight does not exceed 450 kg (992 lb), ensure that the platform is able to lift to the
highest position.
When the platform load is greater than or equal to 540 kg (1190 lb), if the platform lifting height
is greater than 1 m(3.3 ft) or 10% of the height that can be lifted (use the greater number), sev-
eral things will happen. The overload indicator lamp will illuminate, an alarm will sound, and the
work platform will not be able to move. Once you remove the excess weight, the work platform
will be able to move again.
GTJZ1012E
When the weight does not exceed 320 kg (705 lb), ensure that the platform is able to lift to the
highest position.
When the platform load is greater than or equal to 380 kg (838 lb), if the platform lifting height is
greater than 1 m(3.3 ft) or 10% of the height that can be lifted (use the greater number), several
things will happen. The overload indicator lamp will illuminate, an alarm will sound, and the
work platform will not be able to move. Once you remove the excess weight, the work platform
will be able to move again.

work platform will not be able to move. Once you remove the excess weight, the work platform
will be able to move again.
NOTICE
When the temperature of hydraulic oil is low, the viscosity will increase, which will have a significant impact on the
pressure detection. If the environmental temperature difference between the terminal customer and the machine
manufacturer factory delivered by the new machine
≧ 10°(50°F), or if the hydraulic oil temperature is lower than 15
(59°F), an alarm failure occurs when the rated load is lower than the standard rated load (the "OL" symbol appears
on the platform controller screen or the ground controller screen), please re-calibrate the weighing sensor.
A-15 Inspect the Raised Limit Function
1. Park the machine on flat, level and firm ground.
2. Operate on the ground controller and raise the plat-
form to the highest position.
3. Check the height of the platform at this point.
