STARTING AND STOPPING ENGINE
NOTE: Operating engine on angles greater than 25 degrees
will cause the engine to lose lubrication and seize.
Review “Warnings and Safety Precautions” and “Pre-Operation
Inspection” sections before starting engine.
Manual-Start Engine
1. Move engine to a well-ventilated area, always outdoors, to
prevent carbon monoxide poisoning.
2. Move to an area away from flames or sparks, to avoid ignition
of vapors if present.
3. Remove all debris from air cleaner holes and fuel cap to
ensure proper air flow.
4. Press primer bulb three times. Let bulb fully recover between
each depression. SEE FIGURE 3
5. Move throttle between the “HALF” and “FULL” position.
SEE FIGURE 4
6. Grasp starter handle and pull out slowly, until resistance is
felt. Without letting it retract, pull rope with a rapid stroke.
DO NOT pull out the rope all of the way. Let it return to its
original position slowly. Repeat this step until engine starts.
7. After engine begins operating, move throttle lever to “IDLE”
position (SEE FIGURE 4). Run engine for 30 to 45 seconds
at “IDLE” position until engine warms up.
8. After starting the engine, slowly move the throttle control
lever from the “IDLE” position to desired speed as the engine
warms up. SEE FIGURE 4
To Stop the Engine:
1. Set the throttle lever to the “IDLE” position and allow the
engine to run at low speeds for 1-2 minutes before stopping.
2. Move throttle to “STOP” position. SEE FIGURE 4
3. Pull the starter handle slowly and return the handle to its
original position when resistance is felt. This operation will
prevent outside moisture from entering the combustion
chamber.
WARNING
CARBON MONOXIDE GAS IS TOXIC. INHALATION CAN
CAUSE UNCONSCIOUSNESS AND DEATH.
NEVER LEAVE ENGINE RUNNING WHILE UNATTENDED.
