GTTZ10EJ Operation Manual 6-13 © Mar. 2022
1. Start the machine.
2. With the machine in stowed position, move the level
switch in X (side-to-side) or Y (fornt-to-back)
direction by 3°or more, the alarm should not sound.
3. Raise the mast until the lower limit switch
disengages, the display will indicate “LL”(tilt alarm),
and the mast lift and drive functions should be
restricted.
4. Lower the platform to the stowed position, the tilt
alarm should not sound, and the function restriction
should be lifted.
5. Place two wooden blocks under the two wheels on
the front or rear end of the machine. The wooden
block dimension (L×W×H) is 150×100×63mm
(5.9×3.9×2.5in). With the machine in stowed
position, drive the machine on the blocks, the alarm
should not sound.
6. Raise the mast until the lower limit switch
disengages, the display will indicate “LL”(tilt alarm),
and the mast lift and drive functions should be
restricted.
7. Lower the platform to the stowed position, the tilt
alarm should not sound, and the function restriction
should be lifted.
8. Drive the machine off the blocks, and remove the
blocks.
9. Place two wooden blocks under the two wheels on
the left or right side of the machine. The wooden
block dimension (L×W×H) is 150×100×43mm
(5.9×3.9×1.7in). With the machine in stowed
position, drive the machine on the blocks, the alarm
should not sound.
10. Raise the mast until the lower limit switch
disengages, the display will indicate “LL”(tilt alarm),
and the mast lift and drive functions should be
restricted.
11. Lower the platform to the stowed position, the tilt
alarm should not sound, and the function restriction
should be lifted.
12. Drive the machine off the blocks, and remove the
blocks.
Testing the 7°level switch
1. Start the machine.
2. With the machine in stowed position, drive the
machine on a slope exceeding 7°, the red indicator
light of the level sensor should come on, and the
drive speed should be reduced to the low speed
mode (0.6km/h[0.37mph]).

3. Drive the machine off the slope.
TESTING THE WEIGHING
SYSTEM
NOTICE
Perform the test on the ground using platform
controls. Do not stand on the platform.
Before the testing, fully raise and lower the mast and jib
boom for twice to ensure the wear pads and tracks are
properly lubricated.
1. Fully lower the mast, and gradually apply loads to
the platform.
2. When the loads on the platform do not exceed
200kg (440 lb), the mast can be raised to the full
height.
3. When the loads on the platform exceed 240kg (529
lb), the overload alarm should sound, the display
should indicate“OL”, and the mast and jib boom lift
functions should be restricted.
4. Remove the excessive loads from the platform, the
machine functions should be resumed.
