■ RESTARTING ENGINE WHILE ENGINE IS HOT
1. When restarting the engine immediately

after stopping it, leave the choke open. 

2. If the engine won't start after several

attempts, close the choke and repeat
pulling the rope or remove the spark plug
and dry it. 

■ STOPPING ENGINE
Release the throttle lever to the idling
position and press the stop switch (red
button) until the engine comes to a complete
stop. 

Except for an emergency, avoid stopping the
engine while pulling the throttle lever. 

■ ADJUSTING IDLE SPEED
1. When the engine tends to stop frequently

at an idle mode, turn the adjusting screw
clockwise. 

Warm up the engine before adjusting the idle
speed. 

■ STARTING ENGINE
1. Rest the unit on a flat, firm place. 
2. Pump the primer until fuel flows out in the

clear tube. 

3. Move the choke lever upward to close the

choke. 

4. Holding the blower handle, pull the starter

rope with your right hand. (Throttle lever in
idling position.)

Avoid pulling the rope to its dead end or
returning it by releasing the knob. Such
actions can cause starter failures. 

5. When the engine has started, move the

choke lever gradually downward to open
the choke. 

6. Allow the engine to warm up for a half

minute before starting operation.
