If supplemental information is needed for these symbols and marks, explanations will be added in the text instead of using the symbols or marks. Never start the engine in an unventilated place.Using improper parts may unsmooth control and premature worn out.Rubber parts may become deteriorated when Special tools are designed for removal and old, and be damaged by solvent and oil easily. In the contact surface has any damage. And the two posts of battery have to be greased after connected the cables. Then, conduct the service Check if the terminal is covered by the boot. operation. Do not let boot open facing up. Secure wires and wire harnesses to the frame Do not pull the wires as removing a connector with respective wire bands at the designated. And then conduct connection operation later. Clean rust Wire harnesses routed along the handlebar should not be pulled too tight or have excessive slack, be rubbed against or interfere with adjacent or surrounding parts in all steering. Please see standard values for those not listed in the table.Check oil level with oil dipstick So not screw the dipstick into engine as checking. If oil level is nearly low level, fill out recommended oil to upper level. Turn off the engine. Gear Oil Change Remove oil inspection bolt. Remove drain plug and drain oil out.

Full open the throttle valve, and rotate the engine by means of starter motor. Lift the front wheel out of ground. Turn handle from right to left alternative and check if turning is smoothly. Brake Fluid Check brake fluid level in the brake fluid reservoir. If the level is lower than the LOWER limit, add brake fluid to UPPER limit. Replace the brake lining if the wear limit mark closed to the edge of brake disc. Caution It is not necessary to remove brake hose when replacing the brake lining. Headlight Distance Adjustment Turn on main switch Headlight beam adjustment. Check oil level with oil dipstick. So not screw the dipstick into engine as checking. If oil level is nearly low level, fill out recommended oil to upper level. Make sure that pump shaft can be rotated freely. Remove 2 screws on the oil pump, and then remove oil pump. Remove drain bolt and drain gear oil out. Install the drain bolt after drained.The engine burns off the blow-by fuel-gas in the crankcase through the fuel-air separating device. ECU controls the fuel pump relay to make the fuel pump operate. Note The pendulum-type roll over sensor will cut off the power supply of ECU. Main switch should be turned Key-on again before the engine can be restarted. The electrical resistance value goes down when the temperature rises. When it is rotated, both electric resistance and voltage value change, determining the throttle position. Basic Principle When the engine RPM and throttle opening are higher than the default value, ECU controls AISV opening or closure. It has 3-pin socket on the sensor. And, the rest one is for ground.http://www.fuchingrading.com/upload/file/99k-singer-sewing-machine-manual.xml At this point once again to restart the engine, the need to re-open a main switch.
