Cleaning Operation: Flammable liquid can not be used for cleaning the stacker. Before cleaning, take safety
precautions to prevent electric sparks (e.g. sparks caused by short circuit). When operating the accumulator,
connectors on it must be disconnected. Use soft air suction or compressed air, non-conductive and anti-static
brushes to clean electric and electronic components.
Operation of Electric System: Operation on the electric system should only be performed by specially trained
personnel. Before performing any operation on the electric system, precautions must be made to prevent elec-
tric shock. When operating the accumulator, connectors on it must be disconnected.
Wheels: Quality of the wheels has signicant eect on stability and driving performance of the truck. Modica-
tion on wheels can be performed only with the approval from the manufacturer. When replacing wheels, ensure
that the truck is levelled as delivery state (wheels must be replaced in pairs, i.e. replace right wheel together with
left one).
Hydraulic oil pipe: The oil pipe must be changed every 6 years. When change the hydraulic assembled parts,
the oil pipe should be also changed.
Routine Maintenance
1. Check the condition of each pole, cable and protective cover of the accumulator.
2. Check whether the battery box is secure.
3. Check whether the truck is oiled.
4. Check the situation of fork, oil pipe and horn.
5. Check the braking condition.
6. Check the wear condition of driving wheel, load wheel and so on.
Maintenance periods listed in this manual apply to single shift a day under normal operation conditions. If using
in dusty environment, the ambient temperature varies remarkably or in multi-shift situation, the maintenance
period has to be shortened.
Maintain the truck according to following maintenance list. Maintenance periods are as follows:
W1 = Every 50 work hours, but at least once a week.
M3 = Every 250 work hours, but at least once every three months
M6 = Every 500 work hours, but at least once every six months
M12 = Every 2000 work hours, but at least once every 12 months
Additional operations should be performed in trial run period:
(In initial 50 – 100 working hours or after two months)
• Check the nuts on the wheels, and tighten them if necessary.
• Check the hydraulic components for leakage, and tighten them if necessary.
• Replace the hydraulic lter.
