1. Mix gas with oil. Fill fuel tank with fuel/oil mixture. See
Oil and Fuel Mixing Instructions.
NOTE: There is no need to turn the unit on. The
On/Off Stop Control is in the ON ( I ) position at all
times (Fig. 19).
2. Fully press and release the primer bulb 10 times,
slowly. Some amount of fuel should be visible in the
primer bulb and fuel lines (Fig. 20). If you can’t see
fuel in the bulb, press and release the bulb as many
times as it takes before you can see fuel in it.
3. Place the blue choke lever in Position 1 (Fig. 20).
4. Crouch in the starting position (Fig. 21), squeeze the
throttle lock-out and throttle control (Fig. 19), and pull
the starter rope out with a controlled and steady
motion 5 times.
NOTE: The unit uses Spring Assist Starting™, which
significantly reduces the effort required to start the
engine. You must pull the starter rope out far enough
to hear the engine attempt to start. There is no need
to pull the rope briskly-- there is no harsh resistance
when pulling. Be aware that this starting method is
vastly different from (and much easier than) what you
may be used to.
5. Place the blue choke lever in Position 2 (Fig. 20).
6. While squeezing the throttle lock-out and throttle
control, pull the starter rope out with a controlled and
steady motion until the engine starts.
7. Squeeze the throttle lock-out and the throttle control
for 15 to 30 seconds to warm up the engine.
NOTE: Engine may take longer to warm up and reach
maximum operating speed at colder temperatures.
NOTE: Unit is properly warmed up when engine
accelerates without hesitation.
8. Once the engine is warmed up, place the blue choke
lever in Position 3 (Fig. 20). The unit is ready for use.
IF... the engine hesitates, return the blue choke lever to
Position 2 (Fig. 20) and continue warm-up.
IF... the engine does not start, go back to step 2.
IF... the engine fails to start after a few attempts, place the
blue choke lever in Position 3 and squeeze the
throttle control. Pull the starter rope out with a
controlled and steady motion 3 to 8 times. The
engine should start. If not, repeat.
IF WARM... If the engine is already warm, start the unit
with the blue choke lever in Position 2. After the unit
starts, move the blue choke lever to Position 3.
STARTING/STOPPING INSTRUCTIONS
WARNING: Avoid accidental starting. Make sure you are
in the starting position when pulling the starter rope
(Fig. 21). To avoid serious injury, the operator and unit must
be in a stable position while starting.
Make sure that any Add-On item is installed correctly and
secure before starting the unit.
WARNING: Operate this unit only in a well- ventilated
outdoor area. Carbon monoxide exhaust fumes can be lethal
in a confined area.
