Maintenance and adjustment procedures
The section describes the servicing procedures for each item of the Periodic Maintenance requirements.
Storage battery
Inspect at initially 1000KM（600 miles，2 months），
andevery 6000KM（4000 miles，12 months）thereafter
□ Uncover seat, and then remove the battery box cap in the
Middle of helmet barrel.
□ Disconnect negative pole line end, positive end, and then remove battery；
□ Measure the voltage between the two ends of battery with
voltage gauge，charge if the voltage is below 12V
13
Cylinder head nuts and exhaust pipe bolts
Tighten at initially 1000 km（600 miles，2 moths），and
every 6000 km（4000 miles，12 months）
If cylinder head nuts are not tightened to the
specified torque, may result in leakage of
compressed fuel-air mixture and reduce output,
tighten the cylinder head nuts in the following
procedures:：
1． Remove the frame lower covers.
2． Remove the cylinder head cover bolt.
3． Remove spark plug cap.
4． Tighten the nuts evenly one by one to the
their specified torque. Tighten the nuts in the
order indicated.
Tithtening torque：：：：
Cylinder head nut：：：：15-18N.m
Exhaust pipe bolt：：：：15-18N.m
Cylinder and cylinder head
Remove carbon every 6000 km（ 4000
miles，12 months）
Carbon deposits in the combustion chamber and the
cylinder head will raise the compression ratio and may cause
preignition and overheating. Carbon deposited at the exhaust
port of the cylinder will prevent the flow of exhaust gases,
reducing the output. Remove carbon deposits periodically.
14
SPARK PLUG
Neglecting the spark plug maintenance eventually leads to
difficult starting and poor performance. If the spark plug is used for a
long time, the electrode gradually burns away and carbon builds up
along the inside part. In accordance with the periodic table, the plug
should be removed for inspection, cleaning and to reset the gap.
Carbon deposits on the spark plug will prevent good sparking
and cause misfiring. Clean the deposits off periodically.
If the center electrode is fairly worn down, the plug should be
replaced and the plug gap set to the specified gap using a
thickness gauge.
Thickness gauge
Spark plug gap：0.6-0.7 mm (0.024-0.028 inch)
Check the spark plug for burnt condition. If abnormal replace the spark
plug as indicated in the chart.
NGK TROCH REMARKS
BPR7HS E8RTC
If the standard plug is apt to get wet,
replace with the plug.
BPR8HS E7RTC Standard
BPR9HS E6RTC
If the standard plug is apt to
overheat, replace with the plug.
Tighten the spark plug to the specified torque.
Spark plug
Tightening torque:15-18N.m
NOTE:
To check the spark plug, first make sure that the fuel used is
unleaded gasoline, and if plug is either sooty with carbon or
burnt white, replace it.
Confirm the thread size and reach when replacing the plug.
FUEL LINE
Inspect at initially 1000 km (600 miles,2 months) and every
6000 km (4000 miles,12 months), replace every 4 years.
15
AIR CLEANER
Clean every 3000KM（2000 miles）

BRAKES
Inspect at initially 1000 km（（（（600 miles，，，，2 months）））） and
every 6000 km（（（（4000 miles，，，，12 months））））thereafter, replace
brake fluid every 2 years, replace brake hose every 4 years.
Front brake fluid level
Keep the scooter upright and place the handlebar staight.
Check brake fluid level by observing the lower limit line
on the brake fluid reservoir.
When the level is below the lower limit line, replenish with
Brake fluid that meets the following specification.
Specification and classification：：：：DOT4
QIANJIANG BRAKE FLUID
WARNING：：：：
The brake system of the scooter is filled with a glycol-based brake the lowest line
Fluid. Do not use or mix different types of fluid such as silicone-based and petroleum-based. Do not use any
brake fluid taken from old, used or unsealed containers. Never reuse the brake fluid left over from the
last servicing and stored for long periods.
18
WARNING：：：：
Brake fluid, if it leaks, will interfere with safe running and immediately discolor painted surfaces.
Check the brake hoses for cracks and hose joints for leakage before riding.
Brake pads
Wearing condition of brake pads can be checked by observing the limit
Line ① marked on the pad. When the wear exceeds the limit mark, replace
The pads with new ones.
Bleeding air from the brake fluid circuit
Air trapped in the fluid circuit acts like a cushion to absorb a large
proportion of the pressure developed by the master cylinder and thus
interferes with the full braking performance of the brake caliper. The
presence of air is indicated by “sponginess” of the brake lever and
also by lack of braking force. Considering the danger to which such
trapped air exposes the machine and rider, it is essential that, after
remounting the brake and restoring the brake system to the normal
condition, the brake fluid circuit be purged of air in the following manner:
Fill up the master cyliner reservoir to the upper end of the inspection
window. Replace the reservoir cap to prevent entry of dirt.
Attach a pipe to the caliper bleeder valve, and insert the free end of
The pipe into a receptacle.
□ Bleed air from the bleeder valve.
Squeeze and release the brake level several times in rapid succession. And squeeze the lever fully without
releasing it. loosen the bleeder valve by turning it a quarter of a turn so that the brake fluid runs into the
receptacles: the will remove the tension of the brake lever causing it to touch the handlebar grip. Then, close the
valve, pump and squeeze the lever, and open the valve. Repeat the process until the fluid flowing into the
receptacle no longer contains air bubbles.
19
NOTE：：：：when bleeding the brakign system, replenish the brake fluid reservoir if necessary.
Make sure that there is always some fluid visible in the reservoir.
Close the bleeder vavle, disconnect the pipe. Fill the reservoir with brake fluid to the upper end of the
inspection window.
BLEEDER VALVE
TIGHTENING TORQUE: 6-9N.m(0.6-0.9kg-m,4.5-6.5lb-ft)
CAUTION：
Handle brake fluid with care: the fluid reacts
chemically with paint, plastics, rubber materials, etc.
Rear brake
Turn adjusting nut ① so that the the play ② of
Brake lever is 15-25MM as shown in the illustration.
Brake shoe wear：
The vehicle is equipped with the brake lining limit
Indicator ③ on the rear brake.
Inspect brake lining limit as follows：
1. First check if the brake system is properly
Adjusted.
2. when operating the brake, check to see that
the tip of indicator ③ is within the range ④.
3. if the tip of indicator is beyond the range,
the brake shoe assembly should be raplaced with a ②
new set of shoe.

20
Tire
Inspect at initially 1000KM（600 miles，2 months） and every
6000KM（4000 miles，12 months）thereafter
Tire pressure：
If the pressure is too high, the scooter will tend to rede stiffly
and have poor traction. Conversely, if tire pressure is too low,
stability will be adversely affected. Thereafter, maintain the
correct tire pressure for good roadability and to prolong tire life.
CAUTION：
Caution：
The standard air pressure of tires is 175/196Kpa, The use of other
Than standard may cause handling instability. It is highly
recommended to use a QIANJIANG genuine tire.
Tire tread condition：
Operating the scooter with the excessively worn tires will decrease
riding stability and consequently invite dangerous situation. It is highly
recommended to replace the tire when the remaining depth of tire tread
reaches the following specification.
Front and rear：1.6MM（0.064IN）
Tire depth gauge
Steering
inspect at initially 1000KM（600 miles，2 months）
and every 6000KM thereafter.
Steering should be adjusted properly for smooth turning of handlebars
and safe running. Too stiff steering prevents smooth turning of handlebars
and too loose steering will cause poor stability.
Check that there is no play in the front fork assembly by supporting the
machine so that the front wheel is off the ground, with wheel staight ahead,
grasp lower shock absorber near the axle and pull forward. If play is
found, perform steering bearing adjustment.
21
Front shock absorber
Adjust at initially 1000KM（600 miles，2 months）
and
every 6000 km（4000 miles，12 months）thereafter.
Inspect the front shock absorber for oil leakage or other damage, and replace the defective parts, if necessary.
Rear shock absorber
Adjust at initially 1000KM（600 miles，2 months）and every
6000 km（4000 miles，12 months）thereafter.
Inspect front shock absorber for oil leakage and other damage, and replace the defective parts if necessary.
