9.1 Repair and Maintenance
Maintenance technician:
The maintenance and service should only be performed by
special personnel trained by the manufacturer. After the technician sent by after-sales
department of the manufacturer completed maintenance and servicing work, they should
sign on the service log.
Lifting of the Truck
: When a truck needs to be lifted for maintenance, the lifting device
must be safe and secure and strictly attached to the lifting point. When the truck is lifted,
appropriate measures must be taken to prevent the truck from slipping or tipping over
(wedges, blocks can be used).
Cleaning Operation:
Flammable liquid can not be used for cleaning the truck. 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 electric shock. When operating the accumulator,
connectors on it must be disconnected.
Welding operations:
To prevent damage to electrical or electronic components, these
electrical components must be removed from the vehicle before any welding operations are
taken.
Installation:
When repairing or replacing hydraulic components, electric and electronic
components, make sure to install them back to their original positions.
Wheels:
Quality of the wheels has significant effect on stability and driving performance of
the truck. Modification 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).
Lifting chain and rollers:
Chain and rollers will be worn quickly without good lubrication.
Perform periodic lubrication according to following maintenance table. Shorten the
lubrication period under adverse operation conditions (such as in dusty and hot
environment).
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.
