Fitting the accessories Screen The screen mounting kit utilises the mirror mounts to fix it to the scooter. Start by sliding 2 of the plastic lugs over the L shaped chrome bars. The bars are handed left and right. Next screw 1 nut onto the short threaded part all the way, finger tight. Put the mirror mount on so that the flat part faces down. Put the other nut on finger tight. Next place the mirror through the hole, though the spacer and screw into the mirror mount on the handle bar.
Top box The top box is supplied with a universal fitting kit. Place the top box centrally on the rack. Hold the long slotted bars under the rack with the edges of the bars facing upwards.

Important Checks The scooter is nearly ready to go, but before you put any petrol or oil into the scooter, there are a few final things that need checking. These checks should be carried out routinely to insure good performance and safe operation. Checking the oil The engine oil dipstick and cap are combined and is located on the right side of the engine. With the bike on its centre stand and on level ground remove the dipstick and clean it. Re-insert it and remove it again.
Brakes Checking the front brake Check the brake for normal performance and adjust it’s free play. The free play refers to the distance for which the front brake lever travels freely to achieve the braking effect. Required free play : 5 to 10 mm. This must be checked with steering at left, right and centre. Checking the back brake Measure the traveling distance of the rear brake lever before the brake begins to create the braking effect, which should be within 10 to 20 mm from the top end of the brake lever.
Checking the tyre pressure The tyre pressure is 1.75 bar for the front tyre and 2.0 bar for the rear. If you are carrying passengers or luggage please increase the rear tyre to 2.25 bar. If you are a light person or heavy person these pressures may need adjusting to compensate. Check the tyre surface that there are no cuts, nails or sharp objects and that the wheel rim has no impressions, dents or deformations.
Suspension The suspension should be nice and free and should return to its normal position when bounced up and down. There should be no leaks. Fuel / Vacuum Pipes Please check that all fuel / vacuum pipes are connected and that there are no loose pipes.
Electrics Please go through the controls and make sure that the following systems are working correctly; Indicators: left and right, front and rear. Lights: sidelights, front and rear. High and low beam for the front light. Rear brake light, working from both the front and rear brake independently. The horn: It should be a sharp loud noise. The main fuse is located next to the battery and is rated at 15 amps. Do not use a larger fuse. Throttle Test that the throttle is fully operational.
General ‘walk around’ Before use please go around the scooter and check that all nuts and bolts are tight and secure and that there are no loose parts. Starting the scooter Before starting you need to put petrol in. The petrol cap is either located under the seat or at the rear of the foot well under a locked flap. These scooters use normal unleaded (90> octane). You must not over fill with petrol as any spillages will damage the paint and may spill onto a hot engine creating a hazard.
Riding the Scooter Please always wear a HELMET and PROTECTIVE CLOTHING! Familiarise yourself with the controls BEFORE you go out on a public road. Take the appropriate training if you do not all ready know how to ride a scooter. Failure to do so could put yourself or others at risk of injury! The controls are designed for ease of use. The right hand controls the throttle front brake and the switch for the lights and starter.
CAUTION: Always start the engine with the rear brake pedal depressed. The engine should not be allowed to run too fast when it is being warmed up. Quick opening and closing of the throttle must be avoided. Running in Your new scooter requires a ‘running in’ period. This is very important because it allows the mechanical parts to bed in and will increase the serviceable life of the machine.
Storage When not using your scooter a waterproof cover should be used to protect the scooter from the elements. If storing the scooter for periods in excess of six weeks it is advisable that a few further things are done. Drain the fuel. You will find the drain cock at the lowest point of the carburettor. Disconnect the battery and leave it on a ‘trickle’ charger such as an ‘optimate’. Raise the wheels off the floor. Take the spark plug out and put 15ml of oil into the cylinder and turn the engine over.
Cleaning Your new machine should be cleaned on a regular basis. This stops the ingress of corrosion, maintains its lustrous finish and gives you a chance to observe anything that may be broken or damaged. The bike should be washed off in warm soapy water using a sponge or soft cloth. Please use a detergent designed for scooters as washing- up liquids and wash’n’wax style soaps are not fit for the purpose. Do not use a pressure washer. A hosepipe with a spay attachment is ok.
22
Repeat same service intervals when exceeding 31000kms / 64 months from the table above.
Troubleshooting Checking the carburettor In the unlikely event that your scooter fails to start please check the air pilot screw on the side of the carburettor. It should be 2.5 turns out. Screw all the way in and count the number of turns out.
Checking the spark plug A dirty spark plug with dirty electrodes or excessive gap between electrodes will not be able to generate full sparks. (Cleaning) • The best result can be achieved if you clean the spark plug with a spark plug cleaner. • If you do not have such a cleaner, you can clean it with a wire brush. (Adjusting the gap between electrodes) • The side electrode gap should normally be within 0.6 to 0.7 mm (as shown in the figure).
Checking the fuse Turn off the master switch and check the fuse to see if it is blown. Replace the blown fuse with one of the specified capacity: • Always find out the cause before replacing a blown fuse. • Unscrew the two screws battery and remove the battery cover. The fuse is located in the fuse box by the side of the battery. • Open the fuse box and remove the fuse by expanding the fuse clamp from both ends of the fuse.
CAUTION: • When removing the fuse, do not expand the fuse clamp too wide. • After the fuse is installed, check the fuse clamp to see if it runs loose. The fuse will generate heat if the fuse clamp is loose. Which is often the major cause of trouble.
Safety Precautions It is only the driver that can ensure the safety of travel. A safety-minded scooter driver always spends much time learning how to drive and develop his driving skills in a place where traffic is not so busy before he begins to drive on a public road. 1. A great many of scooter accidents are caused by the failure of the car driver to see the scooter driver. The scooter driver should use every means to make himself clearly seen by the car driver.
5. As most serious scooter accidents cause injuries of the drivers head, always wear a helmet and protective clothing such as protective glasses, boots, gloves, thick and strong coat. 6. Do not drive on rough rugged roads as rough surfaces may lead to loss of control and cause damage to the vehicle. Safety Rules 1. Before driving a scooter, be sure to check it carefully (See the section “Inspection before Operation” of the manual). 2.
6. Always remember to switch on the turn signal lights before making a turn or change lanes. 7. Do not drive your vehicle on the shoulder on either side of the road. Loading WARNING: A) The top box is used to carry only lightweight objects, not for very heavy ones. B) When determining if the vehicle is overloaded (the rated load capacity being 150kg), the weights of the objects being carried, the vehicle and the driver should be put together.
