is used for the hydraulic system of the vehicle
and the lifting operation.
Power take-off manipulation methods:
When the vehicle is parked in the operating
position, pull the hand brake, make the engine
idling, step on the clutch pedal to separate the
clutch, and then manipulate the shift lever to
make the transmission in gear 4 state, press
the power take-off switch (11 in Figure 6-11),
release the clutch pedal, then the power take-
off gear and transmission gear mesh smoothly,
the power take-off works. On the contrary, step
on the clutch pedal to separate the clutch, the
power take-off switch reset, manipulate the shift
lever to make the gearbox in neutral position,
release the clutch pedal, then the power take-off
gear smoothly disengages with the transmission
gear.
4. Barometer (5 in Figure 6-4), and the
low pressure alarm indicator light (15 and 16
in Figure 6-7)
The double-needle barometer indicates the
pressure of the service brake of the two-circuit
system, with the normal operating pressure
of 0.45~0.8MPa. If air pressure of any circuit
reduces down to 0.45MPa, you should stop and
check the gas system. In this case, the brake
system malfunction indicator light (7 in Figure
6-7) is on.
When the hand brake circuit pressure of the
gas system is below 0.45MPa, the parking brake
indicator light (Figure 6-7 in sequence 6) goes
a.When using the power take-off switch,
the air pressure should be greater than
0.45MPa. (Low pressure alarm LED is off.)
b.When driving, the power take off
switch must be placed in the OFF position.
