Pull out the dip stick to clean it with cloth, and then
insert it back into original position. Pull it out to
check the oil trace again. The upper end of the oil
trace shall be between MAX and MIN. If it is higher
than MAX, drain oil. If it is lower than MIN, refill it
to standard level.
f. Check brake fluid: Check the brake fluid under the
condition that air has been exhausted from the clutch
system. Refill the brake fluid until the level is
between MAX and MIN. If it is lower than MIN,
refill it to standard level.
4) Check if there is water inside the air reservoir of
exhaust system, and drain if any. Park the vehicle,
pull down or push up the drain valve to drain off the
water condensed in the air reservoir. If any oil-water
mixture is found, air dryer is ineffective and the
desiccant of air dryer shall be replaced immediately.
5) Check the tire pressure. If the pressure is
inappropriate, use a specialized inflation pump to
inflate the tire.
6) Check the lubricant, coolant and air duct for
leakage.
7) Check engine air intake system.
a. Check the primary filter inlet for blockage by
foreign matters to avoid too much negative pressure
present in the air intake system; for this purpose,
insert a thin rod through the primary filter inlet to
move the impeller, checking if the impeller rotates
smoothly. Otherwise, check or replace the primary
filter to prolong the maintenance interval of air intake
system.
b. Check the air filter outlet to the supercharger inlet
pipeline for damage, and repair or renew it in time
when necessary. Otherwise, serious early wear will
occur to the engine.
c. Check the air filter blockage alarm indicator for
