STARTING/STOPPING INSTRUCTIONS

•STARTING A COLD ENGINE

NOTE: This product is designed to be started at idle.

1.Pump primer bulb10 X by pressing up on the bulb

(D). (Fig. 10)

2.Your unit is designed with a 3-position choke: FULL CHOKE , HALF CHOKE and RUN.

Move choke lever to FULL CHOKE position. (Fig. 9)

NOTE: Easy Start power assist starting significantly reduces the pulling effort. Pull the starter cord slowly until fully extended, the power assist will turn over the engine with little resistence from the engine.

3.Squeeze throttle trigger and turn throttle adjuster clockwise until it stops.

Throttle adjuster position：

(1)Idling

(2)Full Throttle (Fig.11)

4.With the unit on the ground,hold the top assist handle and step on the bottom of the frame with your foot. (Fig.12)

Pull starter rope slowly until engine sounds as if it is trying to start, but do not pull rope more than 6 times.

5.Move choke lever to HALF CHOKE position. (Fig.13)

6.Pull starter rope slowly until engine starts.

7.Allow engine to run 10 seconds; then, move the choke lever to RUN position.(Fig.14)

8.Press trigger to run.

NOTE: Always pull starter rope straight out. Pulling starter at an angle will cause rope to rub against the eyelet. This friction will cause the rope to fray and wear more quickly.

Always hold starter handle when rope retracts. Never let a rope snap back from extended position. This could cause rope to snag or fray and also damage the starter assembly.

•STARTING A WARM ENGINE

1.Move choke lever to HALF CHOKE position. (Fig.13)

2.Pull starter rope slowly until engine starts.

3.Allow engine to run 10 seconds; then, move the choke lever to RUN position.(Fig.14)

NOTE: If engine has not started, pull starter rope 5 more pulls. If engine still does not run, it is probably flooded. Move the choke lever to the RUN position. Grip starter handle and pull starter rope slowly rope to clear the engine of excess fuel. If engine fails to srart after repeated attempts, refer to troubleshooting section.

•IMPORTANT IDLING INFORMATION

In some cases due to operating conditions (altitude, temperature etc.) your blower may need a slight adjustment to the idle speed.

If unit does not idle after restarting 2 times after warm up, follow these steps to adjust idle.

1.Locate the idle adjustment screw (G) on the carburetor (Fig. 15).

2.Using a Phillips or slotted screwdriver - turn screw 1/4 to 1/2 turn clockwise (to the right). Unit should then idle properly.

•STOPPING THE ENGINE

Emergency Stopping Procedure. When it is necessary to stop blower engine immediately, press and hold the ON/STOP switch (A) until the engine stops completely (Figure 16).

Normal Stopping Method. For normal stopping, release trigger and allow engine to return to idle speed. Then press and hold the ON/STOP switch (A) until the engine stops completely. (Figure 16)

•BLOWER OPERATIONS

WARNING: Because of flying debris, always, approved shielded safety glasses or face shield when operating blower.

WARNING: Before using your blower, review Safety Precautions in your User Manual, and all regulations for operation of the unit. These precautions and regulations are for your pro- tection.

WARNING: DO NOT operate the blower with other people or animals in the immediate vicinity. Allow a minimum of 30 feet (10 meters) between operator and other people or animals.

1.Use the blower for trees, shrubs, flower beds, and hard-to-clean areas.

2.Use the unit around buildings and for other normal cleaning procedures.

3.Use the blower around walls, overhangs, fences, and screens.

4.We recommend that a face mask be worn when operating blower in dusty areas.

5.Stand away from the debris, at a distance that will easily allow you to control the direction of blown debris. Never blow debris in direction of bystanders.

6.To control velocity of airstream, blower can be operated at any speed between idle and full throttle. Experience with the unit will help you determine the amount of airflow necessary for each application.

7.Operate power equipment only at reasonable

hours-not early in the morning or late at night when people might be disturbed. Comply with times listed in local ordinances.

8.To reduce sound levels, limit the number of pieces of equipment used at any one time.

9.Operate power blowers at the lowest possible throttle speed to do the job.

10.Check your equipment before operation, especially the muffler, air intakes and air filters.

11.Use rakes and brooms to loosen debris before blowing. In dusty conditions, slightly dampen surfaces when water is available.

12.Conserve water by using power blowers instead of hoses for many lawn and garden applications, including areas such as gutters, screens, patios, grills, porches and gardens.

13.Watch out for children, pets, open windows or freshly washed cars, and blow debris safely away.

14.Use intermediate tube plus nozzle of your choice so the airstream can work close to the ground.

15.After using blowers and other equipment, CLEAN UP! Dispose of debris in trash receptacles.
