Operation Manual of WEICHAI GENSET
5 Maintenance
Overall introduction
GENERAL
Establish and adhere to a definite
schedule for maintenance and service
based on the application and severity
of the environment. If the set will be
subjected to extreme operating
conditions, the service intervals should
be reduced accordingly. Some of the
factors that can affect the maintenance
schedule are the following:
Use for continuous duty (prime
power)
Extreme ambient temperature
Exposure to weather
Exposure to salt water
Exposure to dust, sand or other
airborne contaminates.
and clean them if necessary to prevent
the dust or pollutants from causing
electric shock or affecting the cooling
effect of the generator set.
2) Check the fuel, oil and coolant
levels
Fuel level: Do not start the set when
the fuel level is lower than the low
scale. Add proper amount of diesel into
the chassis fuel tank.
Oil level: As shown in Fig. 5-1, when the
oil level is lower than L (low level) scale
or higher than H (high level) scale, do
not start the set. When the liquid level
is lower than L (low level) scale, add the
oil of same grade to H scale. When the
liquid level is higher than the H scale,
discharge a proper amount of oil to the
H scale.

Consult with your local Weichai
Generation distributor if the generator
set will be subjected to any extreme
operating conditions and determine a
suitable schedule of maintenance. Use
the running time meter to keep an
accurate log of all service per- formed
for warranty support. Perform all
service at the time period indicated or
after the number of operating hours
indicated, whichever comes first.
Daily technical maintenance
1) Check the control panel and
generator set for dust accumulation,
Coolant level: When the coolant level is
low, add a proper amount of coolant
into the water tank.
Caution! Do not open the radiator
cover before the coolant is cooled
sufficiently; otherwise, scalds will be
caused easily.
Caution! Do not add a large amount of
coolant when the engine is hot;
otherwise, severe damage will be
caused to the set.
