c. Put the other end of the hose into the oil pot.
d. Remove the upper cover of the front brake main pump
referring to the previous step of adding brake fluid.
e. Rotate the 8# torx wrench with the right hand
counterclockwise to loosen the air nozzle, and with the left
hand, slowly and uniformly squeeze the front brake handle to
the end and keep it still. Lock the vent nozzle clockwise and
slowly loosen the handle. Pay close attention to the liquid
level of the front brake main pump. When it is too low, add it
in time to prevent air bubbles from entering the brake hose.
Repeat the previous steps until the transparent and clean
light yellow brake fluid comes out.
f. Observe whether the liquid level of the main pump is at
3/4 of the transparent inspection, if it is not necessary to add
or withdraw or discharge with a syringe.
g. After the brake fluid is replaced, unplug the 6mm (0.23
in) hose; use a torque wrench to tighten the bleed nozzle to
the standard torque: 10N.m (1 kgf.m, 7 lbf.ft). Then put the
rubber cap on the air nozzle.
h. Reinstall the upper cover of the main pump.
i. Repeatedly pinch and hold the brake handle to check
whether the brake returns to normal hydraulic resistance.
●The discharged brake fluid needs to be properly disposed
of, and it is forbidden to continue to use it. It is forbidden to
dump at will to pollute the environment; or put it at will, etc.
It should be handed over to a qualified recycling unit for
proper disposal.
●The steps of discharging brake fluid must be strictly
performed without confusion; avoid air bubbles from
entering the brake pipeline.
●When pinching the brake handle, it must be slow and
uniform to avoid air bubbles from entering the brake
pipeline.
●The vent nozzle must be locked in place before the brake
handle can be released. Half-locking is forbidden; and do not
use excessive force.
2.2 Replace the rear brake fluid
Refer to the steps for replacing the front brake brake fluid to
replace the rear one.
3. Brake system exhaust
If the hand feel soft when the brake handle is squeezed
and the braking performance is significantly reduced, first
check whether the brake fluid level of the main pump is
lower than the "LOW" line and whether the brake system is
leaking. If the problem still exists after excluding the above
two items, you can try the exhaust operation. The exhaust
operation is similar to the previous operation of replacing the
brake fluid. When replacing the brake fluid, a clean and
transparent light yellow brake fluid must flow steadily, while
the exhaust operation will flow out foamy brake fluid.
After exhausting, check whether the brake fluid level of the
main pump meets the standard.
●The discharged brake fluid needs to be properly disposed
of, and it is forbidden to continue to use it. It is forbidden to
dump at will to pollute the environment; or put it at will, etc.
It should be handed over to a qualified recycling unit for
proper disposal.
● Pay close attention to the liquid level in the main pump
during operation, and replenish it in time to prevent air from
entering the brake hose.
Tire
●Check the tire condition and tire pressure before driving.
●When the tire is worn to the lim it or there are cracks or
wounds on the surface, it should be replaced in time.
●Pay special attention to driving safety when using new tires.
New tires that have not run in well may slip and cause the
vehicle to lose control.
●Avoid sudden acceleration, s harp turns, emergency braking,
etc. within 150 kilometers (93mile) after replacing the new
tire.
●M310 the standard front wheel of this vehicle is 110/80 -14,
and the rear tire is 140/70-14. M125 the standard front
wheel of this vehicle is 100/80-14, and the rear tire is 120/70-
14. M350 the standard front wheel of this vehicle is 120/70-
15, and the rear tire is 140/70-14. When replacing tires, you
should replace standard tires. Use of non-standard tires may
cause problems.
●It is not recommended to use e xternal repair to repair the
tire, the tire needs to be removed for internal repair.
Temporary emergency can use external compensation, but
the vehicle should be driven at a lower speed, and internal
compensation should be made to the maintenance
organization as soon as possible. If the sidewall is bumped,
punctured, scratched, or if the tread is damaged and the hole
is large, it should be replaced directly.
Rebalance should be
done after Tyre repair.
●Check the tire pressure regularly. M310 the standard is
260kPa (2.7 kgf/cm2, 37.7 PSI) under normal temperature
conditions;M125 front tire is 220kPa(2.2 kgf/cm 2
，
32
PSI),rear tire is 270kPa (2.75 kgf/cm2, 39 PSI); M350 the front
tire standard is 240kPa (2.5 kgf/cm2, 35 PSI) and the rear tire
is 260kPa(2.7 kgf/cm2
，
37.7 PSI) under normal temperature
