淤 Stop the vehicle on horizontal
road; Make sure that there is enough
space around the cab before tilting.
Or else, the cab may be damaged
while tilting.
于 Pull up the parking brake; push
the shifting lever into the neutral posi鄄
tion to avoid self-sliding of the vehi鄄
cle.
盂 The cab door must be fastened
up. You should take all articles on
the instrument panel尧 seats and floor
away in case that they damage the
door and the front windshield.
榆 Disengage the locking function of
the cab locking mechanism before
tilting the cab.
虞 After the locking function disen鄄
gaged, hold the tilting rod with hands
and pull up the safety lock hook at
the same time in case of sudden up鄄
lift of the cab.
愚 Raise the cab slowly until it is tilt鄄
ed to the utmost position, and then
lock it reliably with lock arm on the
rear bracket. As shown in the right
figure.
舆 When lowering the cab down, first
hold the tilting rod and disengage
the locking function of lock arm on
the rear bracket, and then lower the
cab down slowly. After the safety
lock locked, lock up the locking
mechanism.
渊2冤Inspection and maintenance
淤 Check the rubber pad assemblies
which are used to strengthen the
front尧rear supports periodically, if
there is any damage, replace the
damaged parts instantly.
于 Check the locking situation of the
locking mechanism periodically, if
locking mechanism is found invalid, it
should be repaired or replaced im鄄
mediately.
盂 If you feel arduous when the cab
is tilted up or feel heavy when the
cab drops down, which indicates
that the torsion bar is invalid, replace
the torsion bar.
榆 If it needs to remove the cab in
chassis repairing, disengage the
force of the torsion bar first and re鄄
move the cab following the steps be鄄
low.
a. Disengage the locking state, and
tilt up the cab to the utmost position.
b. Remove the shaft pin connecting
the rear support bar and the cab
soleplate framework.
c. Push the cab forwards by some
angle until the bolts on the torsion
bar arm can be loosened.
d. After the bolt removed, the torsion
bar does not work and the cab can
be removed (The torsion bar need
not be pulled out).
Note: The above -mentioned work
must be done by three persons at
least because two or three persons
cannot push the cab forwards after
the force of the torsion bar is disen鄄
gaged.
虞 Before reverting the cab to the o鄄
riginal position, return the force of the
torsion bar first. The following steps
should be followed:
a. Put the tooth part of the spline
which is cut at the bottom on one
end of the torsion bar in alignment
with 耶1爷 position on the support axle
tube and the spline tube, and then
insert the torsion bar into the support
axle tube (the locking rod has been
pulled out).
b. After mounting the cab with sup鄄
port axle tube and the left尧 right
brackets to the framework together,
put the 耶1爷 of hub splines on the
torsion bar in alignment with the
spline tooth which is cut at the bot鄄
tom on the other end of the torsion
bar, cover the hub splines on the
torsion bar and insert the spline axle
tube into the right bracket in the cab.
c. Tilt the cab forwards until the bolt
hole on the torsion bar arm aiming at
the screwed hole on the right bracket
in the cab, screw the bolt and tighten
it.
d. Put the cab down slowly, and
check whether the cab is in the state
of suspending in horizontal direction
after dropping down. If normal, lock
the cab up.
愚 If the torsion bar is found invalid,
replace it according to step 榆 and
step 虞.
