5.2.2 As shown in left figure 2, there is a slow button on operation tiller. When press the slow button and rotate the
acceleration knob, the truck will travel with low speed. Such a condition is suitable for turning, stacking and
entering/exiting cargo shelves. When release the slow button and rotate the acceleration knob, the truck will travel at
normal speed.
5.2.3 Safe connection height:
When lift height is about 1.8m (according to the mounted lifting mast); when higher than safe connection height, travel
speed of stacker will be lowered to about 3km/h.
5.2.4 Transporting and stacking operations:
Attention
Check the following items before operating the truck:
Make sure no cargo shall fall or be damaged in the loading area.
Make sure no cargo or objects shall hinder safety.
As shown in figure 2, pull out power supply switch to turn on general power supply, turn on the key, drive the stacker
to cargo pile (fork head 30cm from pile), press the lowering button, adjust fork height to a proper position, insert forks
slowly into cargo pallets as deep as possible, press lifting button to forks 20-30cm above ground, drive the truck to
cargo shelf and park at the position where fork head is 30cm from cargo shelf, press lifting button, forks lift to a proper
height (pallet bottom 10cm higher than shelf), move the cargo slowly to the exact position of shelf, press the lowering
button, place the cargo on the shelf carefully, make the forks away from cargo, start the truck slowly, make the forks
away from cargo pallets (fork head 30cm from shelf), lower the forks to 30cm from ground, and drive the truck away
from the shelf. During travelling, make sure there is no obstacle around. Slow down when turning.
Caution
Different from normal trucks, the driving mechanism of this truck is installed at the front
end of the truck. When turning, the swing speed at the front will be relatively higher,
therefore, when the front end of the truck approaches other objects, make sure to drive
or turn slowly to prevent collision.
5.2.5 Operations of claiming cargo from shelves:
As shown in figure 2, pull out general power switch to turn on power supply, turn on key, drive the truck near cargo
shelf (fork head 30cm from shelf), press lowering button, adjust fork height to the proper position of shelf, insert forks
slowly into cargo pallets as deep as possible, press lifting button, lift cargo to the position where bottom of cargo pallets
is 10cm from shelf, drive truck slowly to make forks away from shelf (fork head 30cm from shelf), press lowering button
until forks are 20-30cm from ground, drive the truck away from shelf to the demanded position, park the truck slowly,
press lowering button to place down cargo, make forks totally away from cargo, and make forks away from cargo
pallets slowly.
5.3 Treatment for abnormal conditions during use:
5.3.1 When press the lifting button, the forks can lift, but when release the button, the forks still lift, and the lifting
becomes out of control. If this occurs, press the general power switch immediately to cut off power supply. Move the
truck to a safe position, lower the cargo manually and repair truck circuits.
5.3.2 If braking failure occurs, stop use immediately and inspect and repair the truck.
