WARNING:

Operate this unit only in a well- ventilated

outdoor area. Carbon monoxide exhaust fumes can be lethal

in a confined area.

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.

STARTING INSTRUCTIONS

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).

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.

Place the blue choke lever in Position 1 (Fig. 20).

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.

Place the blue choke lever in Position 2 (Fig. 20).

While squeezing the throttle lock-out and throttle

control, pull the starter rope out with a controlled and

steady motion until the engine starts.

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.

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.

STOPPING INSTRUCTIONS

1. Release your finger from the throttle control. Allow the engine

to cool down by idling.

2. Press and hold On/Off Stop Control in the OFF (O) position until

engine comes to a complete stop (Fig. 19).
