PRE-OPERATION FUNCTION TEST
GTJZ0608E&0808E Operation Manual 6-7 © Mar 2021
the lift up and drive functions restricted, but the
lowering function allowed.
11. Fully lower the platform. Switch the machine from
lift function to drive function. Drive the machine off
and remove the wooden blocks.
TESTING THE POTHOLE
GUARD
1. Raise the platform until the press plate of scissor is
off the carrier rod of the pothole guard.
2. The pothole guard plate should automatically
extend.
3. Push hard on the left/right pothole guard plate.
Ensure the pothole guard plate cannot be flipped
upward.
4. Lower the platform. The pothole guard plate should
automatically retract.
5. Place a wooden block under the pothole guard and
raise the platform. The wooden block should
measure(L × W × H): 50mm×100mm×50mm
(2in×4in×2in).
6. When the platform raises until the press plate of
scissor comes off the carrier rod of the pothole
guard, the buzzers at the ground and platform
controls should sound, and the display should
indicate “18”, the platform up and drive functions
should be restricted, with only the platform down
function operative.
7. Completely lower the platform and remove the
wooden block.
TESTING THE WEIGHING
SYSTEM(OPTIONAL)
The platform weighing system is optional. Make sure
your machine has this protection function before
checking this function.
1. Park the machine on flat, level and firm ground.
Lubricate 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 the table below:

Models Test Results
GTJZ0608E
When the weight does not exceed 380 kg (838 lb), ensure that the platform is able to lift to the
highest position.
When the platform load is greater than or equal to 450 kg (992 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), the
overload indicator lamp will illuminate, an alarm will sound, the display screen shows “OL”, 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.
GTJZ0808E
When the weight does not exceed 250 kg (551 lb), ensure that the platform is able to lift to the
highest position.
When the platform load is greater than or equal to 200 kg (661 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, the display
screen shows “OL”, 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.
