Introductionóhow to use this manual
The repairing approaches are described step by step:

The illustrations show you what to do and at which position.

The theme of repairing operation tell you what you need to do.

The detailed instruction show you how to accomplish the repairing and
introduce to you other related affairs, such as specification, warning etc.
Example:
Check and adjust the flange bounce
(a) Attach the dial indicator seat to the reducer housing, and touch the
flange face with the measuring head of dial indicator, run the flange
and observe the pendular range of the indicator carefully.
Full bounce tolerance of face : 0.10mm

This formula can help the experienced technicians find out the failure
causes in short time. Overhauling staff can browse the operation theme
and refer to the detailed description thereunder where necessary; impor-
tant specifications and warnings are written out in boldface.
Specification
The corresponding specifications are given in boldface in each repairing
approach of this manual, which allows the overhauling staff to check the
specification while keeping on repairing work.

Overall Repairing Description
1. Keep the vehicle clean and prevent it from
damage with guard plate, seat and floor cover
cloth.
2. Put down the dismantled parts in order during
the dismantle process so as to facilitate the re-
assembly
3. Observe the following items:
a) Disconnect the cable cathode from the
accumulator terminal before the electric
operation;.
b) Disconnect the cable from the cathode
connected to the vehicle body when check-
ing or repairing the accumulator where
necessary.
c) In order to avoid the damage of terminal
post of accumulator, loose the bolts first,
then pull up the cable vertically when
dismantling, don
t wring it or prize it.
d) Clean the terminal posts of the accumula-
tor with dishcloth, and do not scrape them
with file or other similar tools to avoid
damage.e) Mount the cable terminal on the post with loosened nut, then
fasten the nut. donít tap the terminal onto the post with
hammer.
f) Be sure to check whether the cover of positive terminal (+) is
well located or not.
4. Check all hoses and wire plugs to verify whether they are
connected solidly and correctly.
5. Parts that cannot be reused after being used.
a) The following parts should be changed with new one regularly:
split pin, sealing washer, O-ring and oil seal, etc.
b) parts that cannot be reused after being used is marked with

 in the element figure.
6. Pre-coated parts
The pre-coated parts including the bolt and nut are coated with
locking seal glue in factory.
a) In case the pre-coated parts are moved due to its fastening,
loosening or other causes, they must be coated again with the
specified seal glue.
b) Coating procedure of pre-coated parts
1) Clear away the former seal glue from the screw thread of
the said parts.
2) Dry the parts with compressed air.
3) Coat the screw thread of the parts with the specified
locking seal glue.
c) The pre-coated parts are marked with the
 in element
figure.
7. When necessary, sealing agent or sealing ring to prevent the
leakage.
8. Each specification shall be followed strictly. And the torque
spanners should be used.
9. Determine the necessity of using the special service tools (SST)
or special service materials (SSM) according to the real situation.
SST and SSM must be used where necessary and the repairing
should be in accordance with the repairing approach. SST list
and SSM list are attached to this manual.
10. Be sure to check whether the rated current of the new fuse is
correct when changing the fuse. The fuse rated current should
not larger than that of securing fitting and the fuse of smaller
rated current must not be used.
11. Be careful to hang or support the vehicle on the suitable place
when propping up or raising it.
a) In case prop up the vehicle at the front or back part, the wheels
must be blocked to guarantee the safety work. Introduction
