4.4.2 Motor functioning
4.4.2.1 MOTOR FUNCTIONING
Warm up the engine more or less 3 minutes long.
Do not unloose or adjust the speed limiting screw and the limiting
screw of fuel ignition, as by so doing you could negatively affect the
motor efficiency.
4.4.2.2 CHECKS TO BE DONE WHILE THE MOTOR IS WORKING
1. Is there any strange noise or vibration?
2. Does the motor turn “roughly” or is there any burst in it?
3. Does the exhaust gas have a particular colour (black or white)?
In case you find one of this problems, please contact one of the
Yanmar distributors.
Do not touch the exhaust muffler during the motor functioning or
immediate after it has stopped, as the temperature of the muffler is
very high. Never fuel while the motor is on.
4.4.3 Motor stop
1.
Before stopping the motor set the
acceleration lever to the position of
minimum speed and then let the motor
idle for 3 minutes.
2.
Set the lever to the position “STOP”.
3.
In case you have a motor with electrical
start, turn the start key to the position
“OFF” (motor stop).
4.
Turn the fuel cock to the position “S”
(closed).
5.
Pull slowly the handgrip of the self-
winding system out until you feel a
strongest resistance (compression
phase) and let it in this position. This will
avoid rust formation when motor is
standstill.
