STARTING DEVICES
Starting with electric starter
Operate starter switch or starter button. Do not engage for more than 5 seconds.
If it doesn’t
start within that time, let it cool before another attempt is made.
Starting with recoil Starter
Hold the handle of the recoil starter with one hand. Brace the engine (or appropriate) with
the other hand. Pull out the handle gently until resistance is felt. Now pull vigorously and
swiftly about one arm length. Let the handle slowly back until all of the cable has reverted
back into the starter housing.
In order to avoid damage to the starter as well as several other possible problems, do not
return handle abruptly or let go of the handle altogether until the cable has returned itself
completely into the housing. Repeat if necessary.
GROOVED BELT REDUCTION DRIVE
ADJUSTING PROCEDURE
Loosen locking bolt slightly. This is an M-10 bolt, which lies perpendicular to the line of the
crankshaft.
Turn the propeller shaft to remove tension from the belt. This should be in a clockwise
direction as viewed toward the PTO.
Take note of direction of belt, remove belt and inspect.
Check bearings for unusual occurrences such as rough rotation. Rock the pulley back and
forth checking for excessive movement in the bearings.
Reinstall belt to turn the same direction as before. Ensure that it is on all the way and all
grooves fit together properly.
Tighten the belt counter-clockwise just to the point that the slack is taken up but yet the belt
is not stretched.
Measure the circumference of the belt.
Adjust the locking bolt to the point where it has some tension, however, you are still able to
turn the propeller shaft with only slight force.
Put a straightedge to the pulleys and adjust the large pulley fore and aft until the grooves are
paralleled and exactly match to the drive pulley.
Rotate the propeller shaft counter-clockwise stretching the belt.
Rotate the large pulley several revolutions.
