2. Weekly maintenance (40 hours)
Add the following maintenance items in
addition to daily maintenance.
1. Air filter maintenance
Generally:
Please maintain the filter after the truck has
been operated for 50-250 hours.
Please replace the filter after six maintenance
cycles.
Caution
If the truck is used in harsh working
conditions, the maintenance and
replacement cycle of the filter should be
more frequent.
For trucks in a harsh working environment with
a large amount of dust, the maintenance and
replacement cycle should be shortened
according to the actual situation, and it is
recommended to maintain the filter every 8-50
hours and replace with a new one every
100-300 hours accordingly.
Maintenance methods:
(1) Air filter housing (2) Dust cup
(3) Safety filter element (4) Main filter element
(5) Exhaust valve
① Under normal conditions, open the
exhaust valve once a week and once a
day when using in dusty areas. This will
remove large particles of dust and dirt.
② If the inside of the air filter housing is dirty
or wet, please wipe it clean with a cloth.
1 Remove the end cover of the air filter.
2
Remove the main filter element and the
safety filter element and then separate them.
3 The main filter element is the outer filter
element. Blow out the dust inside and outside
the main filter element with compressed air.
4 The safety filter element is the inner filter
element: clean it by patting with your hand,
but do not blow it with air. Be sure to follow
this requirement.
Caution
The compressed air pressure must be below
205 kPa.
Warning
Flying dust may get into your eyes, so
protective glasses should be used
before blowing.
Failure to maintain and replace the filter
elements in time as required will lead to
premature engine wear.
