For those parts that will be reused after removal, clean them up and inspect for damages
or cracks. Replace it if damaged.
Ensure vehicle safety after repair or maintenance.
1.5 General Precaution
1.5.1 Avoid Carbon Monoxide Poisoning
CAUTION: Exhausted gas is poisonous. Do not run the engine in a closed or
poorly ventilated area for a long time.
1.5.2 Avoid Corrosion Injury by Electrolyte
CAUTION:
1. Battery electrolyte (dilute sulfuric acid) is highly caustic and can result in burns.
If you spill electrolyte on skin, flush with water and seek for medical attention
immediately.
2. If you spill electrolyte on clothes, ush with water to avoid burns.
3. Keep battery and electrolyte out of reach of children.
1.5.3 Avoid Injury
CAUTION: Wear suitable work clothes, cap, boots, glasses, dust-proof mask, and
gloves if necessary.
1.5.4 Avoid Burns
CAUTION: Engine and mu󰀪er temperatures are still high when the engine is just
stopped for a very short time. Avoid getting burned. Do not touch the engine before
it completely cools down.
1.5.5 Avoid Toxic Coolant
CAUTION:
1. Coolant is poisonous. Do not drink or spill it on skin, eyes or clothes. If you spill
coolant on skin, wash with soap and water. If you spill coolant on eyes, ush with
water and seek prompt medical attention.
2. If coolant is swallowed, induce vomiting and ask a doctor for medical care.
3. Keep coolant out of reach of children, and keep it away from pets.
1.5.6 Avoid Explosions and Fire
CAUTION:
1. Gasoline is highly flammable. Keep gasoline away from sparks. Vaporized
gasoline is also explosive. Fuel and operate vehicle in a well ventilated area.
2. The battery produces ammable and explosive hydrogen when it is charged. It
has the potential danger of explosion if there is a re or sparks. Charge the battery
in a well-ventilated area.
1.5.7 Operational Safety
CAUTION:
1. Be careful not to get pinched by turning parts such as wheels, axles, and
clutches.
2. When more than two persons are working on the vehicle, remind each other of
operational safety.

1.6 Cautions for Removal and Installation
CAUTION:
1. Use only genuine CFMOTO parts, lubricants and service products.
2. Store removed components separately in order for correct installation.
3. Clean the vehicle of mud, dust and debris before servicing.
4. Replace removed seals, o-rings, piston pin retainers, cotter pins with new ones.
5. Elastic retainers might get distorted after disassembly. Do not use loosened
retainers.
6. Clean and blow o󰀨 components after removal. Apply lubricants on the surface of
moving parts before installation.
7. If you do not know the length of screws, install the screws one by one and make
sure they screw in the same depth.
8. Pre-tighten installed bolts, nuts and screws, then torque them to specified
specication. The basic sequence is: from big to small, from inside to outside and
criss-cross.
9.Replace aged rubber parts when assembling. Do not splash gasoline, grease onto
the surface, as this could cause damage.
10. Apply or inject recommended lubricant into the specied lubrication points.
11. Use the correct special tools for removal and installation.
12. When a ball bearing is removed by pressing steel balls, it cannot be reused.
·Replace bearings if the axial or radial free play is too big.
·If the running surface feels uneven, clean with oil and check again. Replace it
if the cleaning does not work.
·When pressing the bearing into the machine or onto the shaft, if the bearing
can not be securely seated, replace it.
13. Install one-side dust-proof bearings in the correct direction. When assembling
open-type or double-side dust-proof bearings, install with the manufacturer’s mark
outward.
14. Install elastic circlips properly. Turn the circlip after assembling to make sure it
has been installed into the slot.
15. After assembling, check that all the tightened parts are properly tightened and
can move smoothly.
16. Brake uid and coolant may damage painting, plastic and rubber parts. Flush
with water if splashed on these parts.
17. Install oil seals with the manufacturer’s mark outward.
·Do not fold or scratch the oil seal lip.
·Apply grease to the oil seal lip before assembling.
18. When installing pipes, insert the pipe until it bottoms in the end of the joint.
Fit the pipe clip, if any, into the groove. Replace pipes or hoses that cannot be
tightened.
19. Do not allow mud or dust into the engine and/or the hydraulic brake system.
20. Clean old gasket and sealant o󰀨 engine casings before assembling with new.
Remove scratches on the joint faces by polishing evenly with a polish stone.
21. Do not twist or bend cables too much. Distorted or damaged cables may cause
poor operation or even damage components.
22. When assembling parts with protection caps, insert the caps to the grooves.

1.7 Engine Break-in
There are many moving components inside the engine such as the piston, piston rings,
cylinder, crankshaft, gears, etc. During the initial use period, proper run-in for every critical
component is necessary. Break-in helps engine components match to each other and
adjust to working conditions. A new engine with careful treatment will have more e󰀩cient
performance and a longer service life.
Recommended break-in period: 20 hours or 320km (200 miles) whichever comes rst.
Operation guide:
0-10 hours or 0~160km (100 miles): Vary throttle position slowly and smoothly. Do not
operate continuously at more than 50% open throttle position. Cool down the engine for
5~10 minutes after every hour of operation. Avoid prolonged heavy acceleration.
10-20 hours or 160~320km (100 miles): Vary throttle positions slowly and smoothly. Do
not operate continuously at more than 75% open throttle position. Avoid prolonged heavy
acceleration.
CAUTION:
1. Maintain and repair as required during the break-in period.
2. After break-in, check and maintain the vehicle before normal use.
1.8 Warranty
Maintenance procedures specied in the schedule should be carried out in CFMOTO authorized
service stations. Otherwise, warranty and warranty rights may be a󰀨ected.
1.9 Fuel, Engine Oil, Transmission Oil and Coolant
Fuel: Octane US: 89 or higher unleaded gasoline. EU: E10 or 95 (RON)
Engine oil: Use of any oil other than those recommended may cause serious engine
damage. CFMOTO recommends the use of 10W-40 for 4-stroke engines. Changing
engine oil viscosity to 5W-40 due to extreme cold environments or 15W-40 due to hot
environments is acceptable. Reference the chart below for ambient temperature and
viscosity choice.
API: SJ or above engine oil.
Transmission oil: 75W-90-GL5.
Coolant: Any commercialy available 50/50 mix
antifreeze with appropriate anti-corrosion and
rust-proof properties. Freeze temperature must be lower than environment air temperature
(Typically -5 °C or lower).
