5 Maintenance
4. Close thee plug and inject long-term coolant
into radiator and spare case.
5. After injection of coolant, start up the engine
and keep it racing for about 5min, and then stop
it. Check coolant level.
■
Using method of antifreeze
（
if long-term storage coolant is used
）
Antifreeze is used to reduce freezing temperature so
as to prevent any damages of cylinder or radiator
caused by freezing of cooling water.
Add permanent-type antifreeze (type PT) and
clean water into radiator and spare case if the
temperature is under 0
℃
. [long-term storage
coolant has been added before delivery (mixing
proportion of original fluid 50%
）
]
Important
* Use antifreeze as per temperature and its
instruction book.
* For other times without using of long-term
storage coolant, replace antifreeze every spring
and autumn.
* Antifreezes with different brands cannot be
used at same time.
5.13 Use of tyres
■
Tyres maintenance
Tyre pressure has great impact on service life of
tyre; therefore, carry out periodic inspection of
tyre pressure and adjust it properly. Check the
pressure before working. Please also check tyre
or wheel hub.
Supplementary
：
* Tyre pressure shall be subject to the regulated
pressure recorded below. In case of over-high
pressure, tyre cracking or personal injury may occur.
* Tyre cracking may occur if there’s cut on tyre;
and replace it with a new one.
* Consult your local distributor for information
about inner tube or steel hub replacement.

1. Over deflection may occur due to low pressure
in tyre; thus wearing may be caused.
2. Tyre pressure shall be appropriate.
3. Over high pressure may reduce traction and
cause slipping as well as cracking.
■
Replacement of tyre
◆
Tyre disassembly
1. Lower working machine, and park it and then
stop the engine.
2. Loosen the bolts of hub for about one circle.
3. Lift tyre and insert a safety block under the tyre
for supporting to prevent accident falling; loosen
hub bolts and remove tyre, then replace it.
◆
Installation of tyre
1. Tighten hub bolts with care while the tyre is
lifted.
2. Lower the tyre and tighten diagonal hub bolts as
per circumferential order with certain torque.

■
Installation direction of tyre
The flange surface of tyre ensures large traction
and floatage even on soft ground. Pay attention to
direction of tyre surface while installation.
