Adjusting Engine Idle Speed
1. Start the engine by following the procedures
described on the preceding pages.
2. Run the engine at idle speed until operating
temperature is reached (in a minute or less).
3.
Use a screwdriver to adjust the engine idle
speed to 2300-2500r/min.
4
. Turn the idle screw
clockwise to increase
engine idle speed. (Fig. 10).
5. Turn the idle screw
counterclockwise to decrease engine idle
speed.
IMPORTANT
Machine tubes and intake cover must be installed
while adjusting engine idle. Engine idle speed
will also be affected if either the intake cover
or machine tubes are blocked, damaged or
incorrectly installed.
Stopping The Engine
1. Cool the engine by allowing it to run at idle
for 2 to 3 minutes.
2. Stop the engine by moving
the stop switch forward.
(Fig. 11).
• Machine noise increases at higher throttle
setting. Always use the lowest throttle setting
required to get the job done.
• Never operate the blower when visibility is
poor.
• Always wear eye protection such as face
shield or goggles while operating this machine.
• Wear a dust mask to reduce the risk of
inhalation injures.
• Wear close-fitting clothing to protect your legs
and arms.
When the Engine Starts
IMPORTANT
For maximum vacuum performance and operating
life, allow the engine to warm before use.
1. Run the engine at idle speed until operating
temperature is reached (in a minute or less).
2. As the engine warms, open
the choke lever gradually by
slowly pushing the choke
lever down to the choke open
run position. (Fig. 9).
3. The machine should now be ready for use.
4. If the engine does not start, repeat the
appropriate starting procedures for “hot” or
“cold” engine. If the engine still will not start,
follow the “Starting a Flooded Engine”
procedure (below).
WARNING
Incorrect spark plug installation Can result in
serious engine damage.
Starting a Flooded Engine
1. Disconnect the spark plug lead, and use
the spark plug wrench to remove the plug in
a counterclockwise direction.
2. If the spark plug is fouled or is soaked with
fuel, clean or replace the plug as required.
3. Clean excess fuel form the combustion
chamber by cranking the engine several
times while the spark is removed.
4. Install the spark plug and firmly tighten it
with the spark plug wrench. If a torque wrench
is available, torque the spark plug to 148-165
inch-pounds. Reconnect the spark plug lead.
5. Repeat the starting procedures for warm
engine.
6. If the engine still fails to fire or start, refer to
the troubleshooting flowchart at the end of
this manual.
