GENERAL INFORMATION Before Servicing Before starting to perform an inspection service or carry out a disassembly and reassembly operation on a quad, read the precautions given below. To facilitate actual operations, notes, illustrations, photographs, cautions, and detailed descriptions have been included in each chapter wherever necessary. This section explains the items that require particular attention during the removal and reinstallation or disassembly and reassembly of general parts. Especially note the following: (1) Dirt Before removal and disassembly, clean the quad. Any dirt entering the engine will shorten the life of the ...
Page 8
GENERAL INFORMATION (6) Force Common sense should dictate how much force is necessary in assembly and disassembly. If a part seems especially difficult to remove or install, stop and examine what may be causing the problem. Whenever tapping is necessary, tap lightly using a wooden or plastic‐faced mallet. Use an impact driver for screws (particularly for the removing screws held by non‐permanent locking agent) in order to avoid damaging the screw heads. ...

GENERAL INFORMATION When installing cir‐clips and retaining rings, take care to compress or expand them only enough to install them and no more. Install the cir‐clip with its chamfered side facing load side as well. Replace any cir‐clips, retaining rings, and cotter pins with new ones, as removal weakens and deforms them, they could become detached while the quad is driven, leading to a major problem. (15) Lubrication Engine wear is generally at its maximum while the engine is warming up and before all the sliding surfaces ...
GENERAL INFORMATION General Precautions WARNING ○ Proper service and repair procedures are important for the safety of the service mechanic and the safety and reliability of the vehicle. ○ When 2 or more persons work together, pay attention to the safety of each other. ○ When it is necessary to run the engine indoors, make sure that exhaust gas is forced outdoors. ○ When working with toxic or flammable materials, make sure that the area you work in is well‐ventilated and that you follow all of the material manufacturer’s instructions. ○ Never use gasoline as a cleaning solvent. ○ To avoid getting burned, do not touch the engine, engine oil, radiator and exhaust system until they have cooled. ○ After servicing the fuel, oil, water, exhaust or brake systems, check all lines and fittings related to the ...

GENERAL INFORMATION Fuel, Oil and Engine Coolant Recommendation Fuel (For USA and Canada) ● Use only unleaded gasoline of at least 87 pump octane (R/2 + M/2) or 95 octane or higher rated by the Research Method. ● Gasoline containing MTBE (Methyl Tertiary Butyl Ether), less than 10% ethanol, or less than 5 % methanol with appropriate cosolvents and corrosion inhibitor is permissible. Fuel (For Other Countries) ● Gasoline used should be graded 95 octane (Research Method) or higher. An unleaded gasoline is recommended. Engine Oil (For USA) ● Dinli recommends the oil which is rated SF or SG under the API(American Petroleum Institute) service classification. The recommended viscosity is SAE 10W‐40. If SAE 10W‐40 oil is not available, select an alternative according to the following chart. Engine Oil (For Other Countries) ● Use a premium quality 4‐stroke motor oil to ensure longer service life of your vehicle. Use only oil which are rated SF or SG under the API service classification. The recommended viscosity is SAE 10W‐40. If SAE 10W‐40 motor oil is not available, select an alternative according to the right chart. Front Differential Gear Oil ● Use hypoid gear oil that meets the API service classification GL‐5 and is rated SAE #80W‐90. Rear Gear (Final) Box Oil ● Use hypoid gear oil that meets the API service classification GL‐5 and is rated SAE #80W‐90. ...
● Use an anti‐freeze/engine coolant compatible with an aluminum radiator, mixed with distilled water only. Water For Mixing ● Use distilled water only. Water other than distilled water can corrode and clog the aluminum radiator. Anti‐Freeze/Engine Coolant ● The engine coolant performs as a corrosion and rust inhibitor as well as anti‐freeze. Therefore, the engine coolant should be used at all times even though the atmospheric temperature in your area does not go down to freezing point. ● Dinli recommends the use of engine coolant is compatible with an aluminum radiator. Liquid Amount of Water/Engine Coolant Solution capacity (total): Approx. 1950 ml ● For engine coolant mixture information, refer to cooling system section in page 7‐2. CAUTION Mixing of anti‐freeze/engine coolant should be limited to 70%. Mixing beyond it would reduce its efficiency. If the anti‐freeze/engine coolant mixing ratio is below 50%, rust inhabiting performance is ...
GENERAL INFORMATION Break‐In Procedures ● During manufacture only the best possible materials are used and all machined parts are finished to a very high standard but it is still necessary to allow the moving parts to “Break‐In” before subjecting the engine to maximum stresses. The future performance and reliability of the engine depends on the care and restraint exercised during its early life. The general rules are as follows. ○ Keep to these break‐in engine speed limits: Break‐in engine speeds Initial 500 km: Less than 1/2 throttle ○ Upon reaching as odometer reading of 500 km you can subject the vehicle to full throttle operation, for short periods of time. ...
