3 OPERATION OF MOTORCYCLE
3.1 Preparation Before Start
3.1.1 Gasoline filling
Before start, check gasoline and oil quantity first . Refill it if gasoline or oil is insufficient . Fill gasoline directly through the filter to gasoline tank . The gasoline level should be 15-20mm below the edge of filler port.
3.1.2 Oil filling
3.1.2.1 The oil level should be maintained between the upper and lower mark
lines of oil dipstick inside crankcase (see Fig.3 ) To measure oil, the threaded
plug should not be screwed in but be on the filler edge. The oil inside gear box
and rear drive casing should be filled to start of threads of the plug.
3.1.2.2 Before oil filling, check the oil drain threaded plugs for being tightened.
3.1.3 After gasoline and oil filling, check handle bar, brake and clutch for reliability and flexibility. Check pressure of tyres, fixation of wheels, connection of sidecar to main frame, electrolyte level of battery, and electric circuit and gasoline (oil) lines for serviceability.
3.2 Engine Start
There are two kinds of starting devices for the
engines listed in this instruction. One is kickstarter and the other is starting
motor and kickstarter. The engine can be started on completion of the above
preparation.
The following steps should be taken for "cold" engin starting.
3.2.1 Turn on the gasoline control knob.
This knob is a three-position one. Left position is ON position, right position
is STANDBY position ( when the knob is set to this position, motorcycle can run
30km more) , and the down position is OFF position.
3.2.2 Set the hand gear shift lever or foot gear shift lever to neutral
gear position between gear positions No.1 and No.2 (see Figs 4 and 5). Check to
see whether the gear lever is at neutral positicn by stepping lightly the
kickstarter . If the wheels wouldn't move, the neutral gear position is properly
set. If the wheels trend to move forward, the neutral gear position is not
properly set. 'I'hen it should be reset. The engine can be started only when the
neutral gear position is properly set.
3.2.3 Press down the button attached on the float chamber cover until
the gasoline spills out from the float chamber cover of the carburetter.
3.2.4 Close the air valve approximately by half (1/2).
3.2.5 Turn outwards the throttle twist grip to the end, then bring it
back to 1/8 full travel.
3.2.6 Step the kick starter for 4-5 times to make the crank shaft operate.
The cylinders suck in some mixed air and oil is supplied to part surfaces in
advance which need to be lubricated.
3.2.7 Cut-in the ignition switch by use of key (turn the key
counterclockwise for daytime driving and vice versa).
3.2.8 Press down the kickstarter slightly by foot to make the brake block
insert into the ratchet wheel of the starting gear (No idle travel is felt).
Then starting can be realized by stepping the kickstarter forcefully. If staring
motor is used, first set the levers to neutral positon. (see Figs 4 and 5),or
hold the clutch lever with left hand to disengage the clutch. Press the starting
button with right hand (each press should not take more than 3 seconds. Interval
between two presses should not be less than 2 seconds. Restarting should be done
one minute later after three successive presses).
Caution: If it fails to start
by trying several times, it is forbidden to successs-vely press the starting
button or step the kickstarter. Otherwise it will shorten the life of battery
and starting mechanism.
3.2.9 After the engine is started, slowly open the air valve according to
the engine operating condition.
3.2.10 According to the operation sound of the engine, rotate the
throttle grip to warm up the engine at low speed and then drive the motorcycycle.
3.3 Astern driving of three-wheel motorcycle (with sidecar)
| For astern driving operate as follows: a. Stop the motorcycle. b. Set the gear to position No. 1 (or neutral) c. Apply the astern lever with teft tiptoe or left sole to Astern position. d. Drive astern the motorcycle with normal driving method Astern operation Positions are shown in Fig 6 3.4 Engine Shutdown 3.4.1 For engine shutdown, reduce the throttle, then turn off
the ignition switch.
In severe cold season, the following procedures should be
taken for parking the motorcycle outside. |
 |
3.5.1 Before parking, set the gasoline control knob to OFF and press
down the float button to make all gasoline remaired in the carburetter burnt
out.
3.5.2 Remove the battery to prevent it from being damaged by frost.
NOTE If starting motor is to be used due to engine
flameout caused by improper operation to the motorcycle, hold the clutch lever
to disengage the clutch, then start the engine with motor. It is not necessary
to neutral position for starting and the gear lever may be set at any position,
but it is better to be set at lower gear position so as to get smooth starting.
If kickstarter is to be used, starting can be performed only when the neutral
pesition is set.
