Hazardous components in exhaust. Do not run the engine in a enclosed or poorly ventilated place for long time. 2. Do not touch the engine or muffler with bare hands after the engine has just stopped to avoid scalding. Wear long-sleeve work clothes and gloves for operation. 3. Battery liquid (dilute sulfuric acid) is highly caustic and may cause burns to skin and eyes. Flush with water if splashed to skin and get immediate medical attention. Flush with water if splashed to clothes to avoid burns. Keep battery and liquid away from reach of children 4. Coolant is poisonous. Do not drink or splash to skin, eyes or clothes. Flush with plenty of soap water if splashed to skin. If splashed into eyes, flush with water and consult the doctor. If drinking the coolant, induce vomit and consult the doctor. Keep coolant away from reach of children. 5. Wear proper work clothes, cap and boots. If necessary, were dust-glass, gloves and mask. 6. Gasoline is highly flammable. No smoking or fire. Also keep against sparks. Vaporized gasoline is also explosive. Operate in a well-ventilated place. 7. When charged, Battery may generate hydrogen which is explosive. Charge the battery in a well-ventilated place. 8. Be careful not to get clamped by the turning parts like wheels and clutch. 9. When more than two people are operating, keep reminding each other for safety purpose. Cautions for Disassembling and Assembling 1. Use genuine CFMOTO parts, lubricants and grease 2. Clean the mud, dust before overhauling 3. Store the disassembled parts separately in order for correct assemble. 4. Replace the disassembled washers, o-rings, piston pin retainer, cotter pin with new ones. 5. Elastic retainers might get distorted after disassembled. Do not use the loosened retainers. 1-1

1. Overhaul Information 6. Clean and blow off the detergent after disassembling the parts. Apply lubricants on the surface of moving parts. Measure the data during disassembly for correct assembling. 7. If you do not know the length of screws, install the screws one by one and make sure they are screwed in with same depth. 8. Pre-tighten the bolts, nuts and screws, then tighten according to the specified torque, from big to small and from inner side to outer side. 9. Check if the disassembled rubber parts are aged and replace if necessary. Keep the rubber parts away from grease. 10. Apply or inject recommended lubricant to the specified parts. 11. Use special tools wherever necessary. 12. Replace the disassembled ball bearings with new ones. 13. Turn the inner and outer rings of ball bearing to make sure the bearing will turn smoothly. Replace if the axial or radial play is too big. If the surface is uneven, clean with oil and replace if the cleaning does not help. When pressing the bearing into the machine or to the shaft, replace the bearing if it could not be pressed tight. 14. Install the one-side dust-proof bearing in the right direction. When assembling the open type or double-side dustproof bearing, install with manufacturer’s mark outward. 15. Keep the bearing block still when blowing dry the bearing after washing clean. Apply oil or lubricant before assembling. 16. Install the elastic circlip properly. Turn the circlip after assembling to make sure is has been installed into the slot. 17. After assembling, check if all the tightened parts are properly tightened and can move smoothly. 18. Brake fluid and coolant may damage coating, plastic and rubber parts. Flush these parts with water if splashed. 19. Install oil seal with the side of manufacturer’s mark outward. Do not fold or scratch the oil seal lip. Apply grease to the oil seal lip before assembling 20. When installing pipes, insert the pipe till the end of joint. Fit the pipe clip, if any, into the groove. Replace the pipes or hoses that cannot be tightened. 21. Do not mix mud or dust into engine and/or the hydraulic brake system. 1-2

1. Overhaul Information 22. Clean the gaskets and washers of the engine casing before assembling. Remove the scratches on the joint faces by polishing evenly with an oilstone. 23. Do not twist or bend the cables too much. Distorted or damaged cables may cause poor operation. 24. When assembling the parts of protection caps, insert the caps to the grooves, if any. 1- 3
