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.
