Lifting of truck
Cleaning operation
If the truck is cleaned by water jet cleaner or high pressure cleaner, all electric elements and electronic
assemblies should be covered in advance to avoid humidity which will cause faults. Cleaning the vehicle by
steam nozzle is prohibited.
Operation of welding
To avoid damage of electric and electronic assemblies, the assemblies should be removed away from the
truck before welding.
Installation
After repair or replacement of the hydraulic components, electric elements and electronic assemblies, ensure
that they are reinstalled to their original positions.
Lifting chain
If the lifting chain is not coated with lubricating oil, it will wear soon. The maintenance cycle stated in service
manual refers to maintenance under the normal condition. Under worse conditions (dusts, temperature) , the
parts should be lubricated regularly.
Hydraulic oil pipe
Oil pipe must be replaced every three years. When replacing hydraulic assembly, the oil pipe of hydraulic
system should be replaced at the same time.
Maintenance
No modifications or alterations to the parts of the stacker, especially the safety device shall be made without
permission. The operating speed of the truck must not be changed.
All original parts have been checked by the quality inspection departments. To ensure the safety and reliability
of the truck, only the manufacturer's parts can be used. Replaced parts, such as oil and fuel must be disposed
of in accordance with the appropriate environmental protection rules.
Only qualified persons specially trained by the manufacturer can carry out maintenance of the truck. The
after-sales service department of manufacturer has dispatched special technicians who can be commissioned
to sign on the maintenance record in the maintenance service appointed by manufacturer.
For lifting of the truck, the hoisting equipment should be safe and reliable (especially the hoisting position).
When the truck is lifted, necessary measures should be taken to avoid slip and turnover of the truck (wedge
block or wood block can be used) . The hoisting equipment can only be used when the forks are fixed and
connecting cable with enough strength is applied.
Flammable fluid is strictly forbidden in cleaning of the truck. Before cleaning work, safety measures must be
taken to avoid sparks (e.g. caused by short circuit) . Any operation of battery should be performed after cutting
off the power of the battery. All electric elements and electronic assemblies can only be cleaned by weak
wind blower or compressed air, or by non-conductive and antistatic brush.
Warning
No modifications or alterations to the parts of the stacker, especially the safety device shall be made without
permission. The operating speed of the truck must not be changed. All electric elements and electronic
assemblies can only be cleaned by antistatic brush.
Operation of electrical system
Operation of electrical system should only be performed by trained professionals. Before any operation of
electrical system, protection measures to avoid electric shock should be properly taken. During operation of
battery, separate the inserts of battery apart to cut off the power of the truck.
Wheels
The quality of wheels greatly affects the stability and driving performance of the truck. Any change to wheels
should be approved by the manufacturer. During replacement of wheels, the truck must be kept level as
original state (wheels must be replaced by pairs, e. g. both left and right) .
