OPERATION
STARTING SWITCH
Starting switch is used to start or stop the engine.
(A): OFF position
The key can be inserted or withdrawn. Switches for the electri-
cal system (except room lamp) are all turned off, and the en-
gine is stopped.
(B): ON position
Electric current flows through the charging and lamp circuits.
Keep the switch at this position while the engine is running.
(C): START position
This is the position to start the engine. Keep the key at this position during cranking and release it immediately
after the engine starts.
When the switch is released, it automatically returns to ON position (B).
(D): HEAT (preheating) position
This is the position to start preheating manually.
When the key is turned to HEAT (preheating) position (D), the HEAT pilot lamp lights up and preheating starts.
When the preheat pilot lamp changes from lighting to flashing, release the key immediately.
When the switch is released, it automatically returns to OFF position (A).
Turn the starting switch key to START position (C) and start the engine immediately.
FUEL CONTROL DIAL
Fuel control dial is used to control the engine speed and out-
put.
(a) Low idle (MIN)
The position where the dial is turned fully to the left.
(b) High idle (MAX)
The position where the dial is turned fully to the right.
REMARK
• When stopping the engine, turn the fuel control dial to the
Low idle (MIN) position and then turn the starting switch to
OFF position.
• Even if the engine is started with the fuel control dial in a
position other than Low idle (MIN) position, the engine
speed is set to low idle.
In this case, you can change the engine speed by turning
the fuel control dial to Low idle (MIN) position and then
turning it toward High idle (MAX) position.
CIGARETTE LIGHTER
The cigarette lighter is used to light cigarettes.
When the cigarette lighter is pushed in, it will return to its origi-
nal position after a few seconds, so pull it out to use it.
If the cigarette lighter is removed, the socket can be used as an
120 W (24 V x 5 A) power source.
NOTICE
This cigarette lighter is for 24 V. Do not use it as a power
supply for 12 V equipment.
