RECOMMENDED FUELS  
BLOWER OPERATIONS  
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: Because of flying debris, always,  
approved shielded safety glasses or face  
shield when operating blower.  
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)  
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).  
8. Press trigger to run.  
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.  
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/STOPPING INSTRUCTIONS  
STARTING A COLD ENGINE  
NOTE: This product is designed to be started at idle.  
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. 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.  
STARTING A WARM ENGINE  
Move choke lever to FULL CHOKE position. (Fig. 9)  
Fig. 17  
Fig. 18  
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)  
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.  
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.  
B
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.  
3. Squeeze throttle trigger and turn throttle adjuster  
clockwise until it stops.

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