• Insert the dipsck into the oil ller neck, but do not screw it in.
• If the oil level is low, ll to the top of the oil ller neck with the recommended oil.
•Use high-detergent, 4-stroke engine oil.
• Cauon: Using non-detergent oil or 2-stroke engine oil could shorten the engine’s service life.
• SAE 10w-30 is recommended for general, all temperature use. Other viscosies shown in the following
gure (Fig. 4) might be used when the average temperature in your area is within the indicated range.

Fuel (Fig. 9)
• Never use an oil/gasoline mixture or dirty gasoline. Avoid geng dirt, dust or water in the fuel tank.
• Refuel in a well-venlated area with the engine stopped. Do not smoke and keep the engine at a safe distance from ames and sparks which can ignite the
fuel.
• Do not overll the fuel tank (there should be no fuel in the ller neck). Aer refuelling make sure the tank cap is closed properly and securely.
• Be careful not to spill fuel when refuelling. Spilled fuel or fuel vapour may ignite. If any fuel is spilled, make sure the area is dry before starng the engine.
• Avoid repeated or prolonged contact of fuel with skin or breathing of vapour.
Warning: Gasoline is extremely ammable and is explosive under certain condions.

STARTING THE ENGINE (FIG. 10-15)
Cauon: Ensure that the clutch is disengaged and that the shi lever is in the neutral posion to prevent sudden uncontrolled movement when the engine
starts. The clutch is engaged by pulling in the clutch lever and disengaged by releasing the lever.
1) Turn the fuel valve to the ON posion, check whether it is ghtened. (Fig. 10)
2) Close the choke lever. (Fig. 11)
Note: Do not use the choke if the engine is warm or the air temperature is high.
3) Turn the engine switch to the ON posion. (Fig. 12)
4) Move the throle lever slightly to the le. (Fig. 13)
5) Pull the starter grip lightly unl resistance is felt and then pull it briskly. (Fig. 14)
Cauon: Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter.
6) As the engine warms up, gradually open the choke. (Fig. 15)

• To use the ller opmally, try to hold the machine at the angle shown while you are lling the ground.
Fig. 21
Tips for proper use
• Adjust the handlebar height to a comfortable posion (waist height for normal lling).
• Should the machine jerk forward while lling, press down the handlebars, if the machine will not move forward, move the handlebars from side to side.
• In order to properly and easily turn the machine during operaon, lower the handlebars to bring the center of gravity towards the rear and then make the
turn.

Changing oil (Fig. 27)
Drain the oil while the engine is sll warm to assure rapid and complete draining.
• Remove the oil ller cap and drain the oil.
• Rell with the recommended oil and check the level.
• Wash your hands with soap and water aer handling used oil.
(1) Drain plug (2) Oil ller cap (3) Upper level Fig. 27
Note: Dispose of used motor oil in an environmentally friendly manner. We suggest you drain used
oil into sealed containers and take them to your local service for reclamaon. Do not throw the
sealed container in the trash or pour used oil on the ground.
Air lter cleaning
• Remove the wing nut and the air cleaner cover. Remove the elements and separate them. Carefully check both elements for holes or tears and replace if
damaged.
•Foam element: Clean in warm soapy water, rinse and allow to dry thoroughly or clean in high ashpoint solvent and allow to dry. Dip the element in clean
engine oil and squeeze out all the excess. The engine will smoke during inial start-up if too much oil is le in the foam.
•Paper element: Tap the element lightly several mes on a hard surface to remove excess dirt or blow compressed air through the lter from the inside out.
Never try to brush the dirt o.
Warning: Never use gasoline or low ash point solvents for cleaning the air cleaner element, otherwise, a re or explosion could result.
Cauon: Never run the engine without the air cleaner. Rapid engine wear will be the result.
Fuel lter (Fig. 28)
• Turn the fuel valve to the OFF posion and remove the fuel lter and the O-ring.
• Wash the removed parts in solvent, dry them thoroughly and reinstall them securely.
• Turn the fuel valve ON and check for leaks.

Spark plug
Recommended spark plug: TORCH F7RTC
To ensure proper engine operaon, the spark plug must be properly gapped and free of deposits.
• Remove the spark plug cap.
• Visually inspect the spark plug. Discard it if the insulator is cracked or chipped.
• Measure the plug gap with a feeler gauge. The gap should be 0.7-0.8mm (0.028-0.031 in), correct as necessary by bending the side electrode.
• Insert the spark plug by hand at rst and then use a wrench to ghten it as much as necessary.
Warning: If the engine has been running the muer will be very hot. Be careful not to touch the muer.
Cauon: The spark plug must be securely ghtened. An improperly ghtened plug can become very hot and possibly damage the engine. Never use a worn
or damaged spark plug.
Clutch cable adjustment (Fig. 29)
Measure the free play at the lever p.
Free play: 3-8mm (0.1 - 0.3 inches)
• If the free play is incorrect, loosen the lock nut and turn the adjusng bolt in or out as required.
• Aer adjustment, ghten the lock nut securely. Then start the engine and check for proper clutch
lever operaon.

Belt tension adjustment (Fig. 31, 32)
• Adjust the clutch lever free play.
• The standard belt tension is 60-65mm (2.4-2.6 in) at the tension roller with the clutch engaged
(clutch lever is squeezed).
• To adjust, loosen the four engine mounng bolts and the engine stay ghtening bolt and move
the engine forward or reverse to get proper tension of the belt.
Note: Aer adjusng the tension, make sure that the outside face of the drive pulley is aligned with
the outside face of the driven pulley by using a straight gauge.
