OPERATION

STOPPING YOUR ENGINE

• Move the ignition switch to the "Stop" position.

• If engine does not stop, move the choke lever to the "Full

Choke" position.

WARNING

When starting the engine, hold the unit as shown

in Figure 13. Do not set the unit on any surface

except a clean, hard area while the engine is run-

ning. Debris such as gravel, sand, dust, grass,

etc. could be picked up by the air intake and

thrown out through the discharge opening, dam-

aging the unit or property or causing serious

injury to bystanders or operator.
For safe starting and operation, follow all safety

precautions in this operator's manual and labels

on the unit. Dress properly before starting engine.
On mulch bladed units, blades are noisy during

start-up.
Avoid any contact with the muffler. A hot muffler

can cause serious burns.

BASIC STARTING PROCEDURE

(Fig. 13

14)

COLD ENGINE START AND WARM ENGINE

START AFTER RUNNING OUT OF FUEL

• Fuel engine with

40:1

fuel mix (3.2 oz. to

gallon gas).

Move

feet (3 meters) away from fueling site.

• Move ignition switch off of the "Stop" position.

• Activate throttle lock.

• Press primer bulb 6 times.

• Actuate choke by moving the choke lever to the "Full

Choke" position.

• Hold the unit in the starting position as shown. When

using the unit as a blower, make sure the blower end is

directed away from people, animals, glass, and solid

objects. When using the unit as a vacuum, make sure the

vacuum end is directed away from people, animals,

glass, and solid objects and that you support the vacuum

extent of the rope. Do not let the starter snap back. Hold

the handle and let the rope rewind slowly.

• Move the choke lever to the "Half Choke" position.

Starting could require pulling the starter rope handle many

times depending on how badly the unit is flooded. If engine

still fails to start, refer to the "Trouble Shooting" chart.
Once the engine starts, allow the engine to run 15

seconds, then move the choke lever to "Off Choke". Allow

the engine to run for 30 more seconds at "Off Choke"

before releasing the throttle lock.

NOTE -

If the engine dies with choke lever at "Off Choke"

position, move the choke lever to "Half Choke". Pull starter

rope three times. Move choke lever to "Off Choke" position,

pull the rope until engine runs. Run engine 30 seconds with

throttle trigger fully squeezed.

• Release throttle lock by squeezing the trigger.

• To stop the engine, move the ignition switch to the "Stop"

position.
