Some conventional petrols are being blended with oxy-

genates such as alcohol or an ether compound to meet

clean  air  standards.  Your  engine  is  designed  to

operate  satisfactorily  on  any  petrol  intended  for  auto-

motive use including oxygenated petrol.

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

CAUTION: NEVER  operate  blower  without

the air filter or dust and dirt will be sucked into

the engine and damage it. The air filter must

be kept clean. If it becomes damaged, install

a new filter.

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: 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.

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)

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.

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.

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.

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)

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.

1.    Follow the instructions “STARTING A COLD 

ENGINE”.

2.    Once unit is running, place unit on your back by 

slipping arms through the shoulder straps as if your 

were putting on a jacket (Fig. 17).

3.    When preparing to clear an area of debris, always 

position yourself so that you can control the direction 

debris will be blown. (Fig. 18)

4.    The control handle and the flexibility of the blower 

tube assembly will allow you to clear the most 

hard-to-reach areas .

5.    The hand grip, throttle trigger, throttle adjuster and 

ignition on/stop switch are all mounted on a swivel 

handle that offers a wide range of operating positions 

and comfort (Fig. 19).
