7. Inspect the oil level of the rear driving according to the above operation procedures.

5.11.2 REPLACEMENT OF THE DRIVE AXLE OIL

It requires replacing drive axle oil within regulated cycle.

The replacement procedures are as follows:

1. Drive the machine to park at a flat ground; slowly move the car with low oil supplying,
to keep the oil outlet screw piston at the end side of the wheel rim of the front drive axle to
be located at the lowest position.

2. As the oil outlet screw pistons at the end side of the wheel rim of the front drive axle
cannot be located at the lowest position at the same time, therefore, the front and rear
drive axles should replace oil twice.

3. Pull up the button of the parking brake to reset it. The handle of the speed changing
should be placed at neutral position, put on frame fixing bar to avoid car moving and
rotating.

4. Run the engine for 10 minutes under idle speed, and the engine turns off.

5. Screw off the oil outlet screw piston at the end surface of the wheel rim of the front
drive axle, and the oil outlet screw piston at the middle part of the axle, drain out the oil
and receive the oil with container.

6. Refuel according to the above-mentioned “drive axle refueling and oil level judgment
criteria”.

7. Screw on the oil outlet screw piston.

8. Repeat the procedure to inspect the oil level of the rear drive axle

9. Since the oil may at relatively high temperature, it is necessary to wear protection
tools and facilities, and handle with care to avoid injuries.

5.12 INSPECTION AND REPLACEMENT OF TIRE

If the tire or wheel rim is handled mistakenly, tire may burst or broken and wheel rim
may be damaged and spread, which may result in serious injury or death.

Maintenance, dismount, repair and installation of tire and wheel rim need special
equipment and know- how, so you must bring it to tire repair shop to repair, or by specially
trained personnel to carry out and comply with all relevant safety requirements.

Recommend to use dry nitrogen (N2) to full the tires. If the original tires are filled with air, it
is recommended to use nitrogen gas to adjust its air pressure, nitrogen can be mixed with
atmospheric gases. Tires filled with nitrogen can reduce the possibility of explosion.
