DANGER

:

 This machine was built to be operated according to the rules for safe operation in this 

manual. As with any type of power equipment, carelessness or error on the part of the operator can 
result in serious injury. This machine is capable of amputating hands and feet and throwing objects. 
Failure to observe the following safety instructions could result in serious injury or death.

General Operation 

1.

Read this operator’s manual carefully in its entirety 
before attempting to assemble this machine. Read, 
understand, and follow all instructions on the machine 
and in the manual(s) before operation. Be completely 
familiar with the controls and the proper use of the 
machine before operating it. Keep this manual in a safe 
place for future and regular reference and for ordering 
replacement parts.

2.

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

3.

Never allow children under 14 to operate the unit. 
Children 14 years and older should only operate under 
close parental supervision. Only responsible individuals 
who are familiar with these rules of safe operation should 
be allowed to use your unit.

4.

Keep the area of operation clear of all persons, 
particularly small children and pets. Stop the engine 
when they are in the vicinity of the unit. 

5.

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.

6.

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 length. They can be caught in moving 
parts. 

7.

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

8.

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. 

9.

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

10. Keep all guards and safety devices in place and 

operating properly.

11. Exercise caution when operating blower. Do not allow the 

discharge to point in the direction of bystanders or pets. 

12. 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 take 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.

13. Muffler and engine become hot and can cause a burn. Do 

not touch. 

14. Do not allow leaves or other debris to build up on 

engine’s muffler. The debris could ignite and cause a fire.

15. 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.

16. Only use accessories approved for this machine by the 

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

17. Only operate unit in good daylight. Do not operate unit at 

night or in dark areas where your vision may be impaired.

18. If situations occur which are not covered by this manual, 

use care and good judgment. Contact your dealer for 
assistance.

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 unit off if a child enters the area.

3.

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