Operation

General Operation:

1. Read, understand, and follow all instructions on the
machine and in the manual(s) before attempting to
assemble and operate. Keep this manual in a safe place for
future and regular reference and for ordering replacement
parts.

2. Be familiar with all controls and their proper operation.
Know how to stop the machine and disengage them
quickly.

3. Never allow children under 14 years of age to operate this

machine. Children 14 and over should read and understand

the instructions and safe operation practices in this manual
and on the machine and be trained and supervised by an
adult.

4. This leaf blower is a powerful tool, not a plaything.
Therefore, exercise extreme caution at all times. It has been
designed to perform one job; to blow leaves. Do not use it
for any other purpose.

5. Keep the area of operation clear of all persons, particularly
small children and pets. Stop the engine when they enter
the vicinity of the machine.

6. Always wear safety glasses or safety goggles during
operation and while performing an adjustment or repair,
to protect eyes from debris or foreign objects that may be
thrown from machine.

7. Wear close fitting slacks and shirt. Shirt and slacks that
cover the arms and legs are recommended. Do not wear
loose fitting clothes or jewelry and secure hair so it is above
shoulder level. They can be caught in moving parts.

8. Do not operate the machine while under the influence of
alcohol or drugs.

9. Never place your hands or any part of your body or
clothing near rotating parts. Keep clear of the discharge
opening at all times. Never insert your hands, fingers,
feet, or any other part of your body or clothing into the
discharge or air intake openings as the rotating impeller
inside the housing can cause serious injury.

10. Never operate machine without directional discharge
chute and plastic impeller guard properly affixed to
machine. These devices shield the operator from accidental
contact with the rotating impeller.

11. Keep all guards and safety devices in place and operating
properly.

12. Exercise caution when operating blower. Do not allow the
directional discharge chute to point in the direction of
bystanders or pets.

13. If your machine should start making an unusual noise or
vibration, immediately stop the engine, disconnect the
spark plug wire and move the wire away from the spark
plug. Allow the machine to stop and perform the following
steps:

a. Inspect for damage.
b. Repair or replace any damaged parts.
c. Check for any loose parts and tighten to assure

continued safe operation.

14. Muffler and engine become hot and can cause a burn. Do
not touch.

15. Do not allow leaves or other debris to build up on engine’s

muffler. The debris could ignite and cause a fire.

16. Do not operate engine if air cleaner or cover over
carburetor air intake is removed, except for adjustment.
Removal of such parts could create a fire hazard.

manufacturer. Read, understand, and follow all instructions
provided with the approved accessory.

20. If situations occur which are not covered in this manual,
use care and good judgment. Contact Customer Support
for assistance or the name of the nearest service dealer.

Children

Tragic accidents can occur if the operator is not alert to the
presence of small children. Children are often attracted to the
blowing activity. Never assume that children will remain where
you last saw them.

1. Keep children out of the work area and under the watchful
eye of a responsible adult other than the operator.

2. Be alert and turn the machine off if a child enters the area.

3. Never allow children under the age of 14 to operate the
leaf blower.

Service

Safe Handling Of Gasoline:

1. To avoid personal injury or property damage use extreme
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive. Serious personal injury can
occur when gasoline is spilled on yourself or your clothes
which can ignite. Wash your skin and change clothes
immediately.

2. Use only an approved gasoline container.

3. Never fill containers inside a vehicle or on a truck or trailer
bed with a plastic liner. Always place containers on the
ground away from your vehicle before filling.

4. Remove gas-powered equipment from the truck or
trailer and refuel it on the ground. If this is not possible,
then refuel such equipment on a trailer with a portable
container, rather than from a gasoline dispenser nozzle.

5. Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do
not use a nozzle lock-open device.

6. Extinguish all cigarettes, cigars, pipes and other sources
of ignition.

7. Never fuel machine indoors because flammable vapors will
accumulate in the area.

8. Never remove gas cap or add fuel while engine is hot or
running. Allow engine to cool at least two minutes before
refueling.

9. Never over fill fuel tank. Fill tank to no more than ½ inch
below bottom of filler neck to provide for fuel expansion.

10. Replace gasoline cap and tighten securely.

11. If gasoline is spilled, wipe it off the engine and equipment.

Move machine to another area. Wait five (5) minutes before
starting engine.

12. Never store the machine or fuel container near an open
flame, spark or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas appliances.

13. To reduce fire hazard, keep mower free of grass, leaves,
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel-soaked debris.

14. Allow a mower to cool at least five (5) minutes before
storing.

General Service:

1. Never tamper with safety devices. Check their proper
operation regularly.

2. Check all nuts, bolts and screws for proper tightness at
frequent intervals to keep the machine in safe working
condition. Also, visually inspect machine for any damage
and repair, if needed.

3. Before cleaning, repairing, or inspecting, stop the engine
and make certain the impeller and all moving parts have
stopped. Disconnect the spark plug wire and ground it
against the engine to prevent unintended starting.

4. Do not change the engine governor settings or overspeed
the engine. The governor controls the maximum safe
operating speed of the engine.

5. Maintain or replace safety and instruction labels, as
necessary.

6. Follow this manual for safe loading, unloading,
transporting, and storage of this machine.

7. Never store the machine or fuel container near an open
flame, spark or pilot light such as on a water heater,
furnace, clothes dryer, or other gas appliances.

8. Always refer to the operator’s manual for proper
instructions on off-season storage.

9. If the fuel tank has to be drained, do this outdoors.

10. Observe proper disposal laws and regulations for gas, oil,

etc. to protect the environment.

Spark Arrestor

WARNING! This machine is equipped with an

internal combustion engine and should not be used
on or near any unimproved forest-covered, brush-

covered or grass-covered land unless the engine’s
