• ADJUST BACK PACK AND HARNESS AND
CONTROL HANDLE
1. Place blower on your
back by slipping arms
through the shoulder
straps as if you were
putting on a jacket (Fig.
8).
2. Once adjustments
have been made, to
the straps for user
comfort, remove the
Fig. 8
blower from your back and place on level ground in
an upright position.
3. Adjust backpack harness and control handle.
FUEL AND LUBRICATION
• FUEL
Use regular grade unleaded petrol mixed with 40:1
custom 2-cycle engine oil for best results. Use mixing
ratios in Section FUEL MIXING TABLE.
WARNING: Never use straight petrol in your
unit. This will cause permanent engine damage and
void the manufacturer’s warranty for that product.
Never use a fuel mixture that has been stored for over
90 days.
WARNING: If 2-cycle lubricant other than
Custom Lubricant is to be used, it must be a premium grade oil for 2-cycle air cooled engines mixed at
a 40:1 ratio. Do not use any 2-cycle oil product with
a recommended mixing ratio of 100:1. If insufficient
lubrication is the cause of engine damage, it voids
the manufacturer’s engine warranty.
• MIXING FUEL
Add oil to an approved fuel container followed by the
petrol to allow incoming petrol to mix with oil. Shake
container to ensure thorough mix.
WARNING: Lack of lubrication voids engine
warranty. Petrol and oil must be mixed at 40:1.

• RECOMMENDED FUELS
Some conventional petrols are being blended with oxygenates such as alcohol or an ether compound to meet
clean air standards. Your engine is designed to
operate satisfactorily on any petrol intended for automotive use including oxygenated petrol.
STARTING/STOPPING INSTRUCTIONS
• STARTING ACOLD 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 protection.
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.
• OPERATION INSTRUCTIONS
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).
