BEFORE STARTING THE 
ENGINE

 

Each time before starting the engine, inspect the entire 
unit to see if every part is in good order and is securely 
tightened in place. If any damage is found in the fuel line, 
the exhaust line, or the ignition wiring, do not use the 
blower until it has been repaired.

IMPORTANT

 

Before starting operation, always make sure to 
check if any obstacles are left inside the volute 
case and net. The obstacles may cause serious 
injury or damage to fan and volute case.

WARNING

 

Check to see if the shock-absorbers <A> have 
become cracked or otherwise damaged. Note that 
failing to replace these rubber and spring mounts 
when they have become cracked or damaged may 
cause the engine to come loose from its frame during 
use, thus resulting in possible serious bodily injury.

 

If cracked, be sure to replace without delay.

WARNING

 

To reduce the risk of injury associated with contact-
ing rotating parts, stop the engine before installing 
or removing attachments.

 

 Never take off the Guard 

Net <B>

 

Always disconnect the spark plug before performing 
maintenance or accessing movable parts.

 

USING THE PRODUCT

WARNING

 

While using the product, if abnormal noise or 
vibration occurs, stop the engine immediately and 
contact the nearest Husqvarna servicing dealer 
for assistance. Checking the fan is very important. 
If the rotating fan should break up, it will lead to 
serious accidents.

 

1. This blower is a backpack type, and is shouldered 

while operating. It is operated and controlled  with 
the handle on the tube by right hand.

2. Check the work area that the blower will be used in and 

remove or cover all valuables that may be damaged by 
the air blast or thrown debris.

3. Make sure you can move and 

stand safely. Check the area 
around you for possible obstacles 
(roots, rocks, branches, ditches, 
etc.) in case you have to move 
suddenly. Take great care when 
working on sloping ground.

4. To reduce the risk of injury 

associated with thrown objects.

a) Watch out for children, pets, open windows or 

freshly washed cars, and blow debris safely away. 

b) Use the full blower tube extension so the air stream 

can work close to the ground. 

c) Do not allow bystanders in work area.
d) Do not point the 

blower tube in the 
direction of people 
or pets.

e) Always check to 

be sure that no 
debris has been 
blown onto someone else’s property.

f) Pay attention to the direction of the wind, do not 

work against the wind.

5. To minimize blowing time.

a) Use rakes and brooms to loosen debris before 

blowing.

b) In dusty conditions, slightly dampen surfaces or 

use a mister attachment when water is available.

c) 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.

6. The blower must not be used while 

on a ladder or scaffolding.

7. Never put the machine down with 

the engine running unless you have 
it in clear sight.

8. Never touch the spark plug or plug 

cord while the engine is in 
operation. Doing so may result in 
being subjected to an electrical 
shock.

9. Never touch the muffler, spark plug, 

or other metallic parts of the engine, 
or area around the engine cover 
while the engine is in operation or 
immediately after shutting down the engine. These 
metallic parts reach high temperatures during 
operation and doing so could result in serious burns.

WARNING

 

The temperature of the machine may increase after 
stopping the engine. Especially never forget to cool 
down the engine before refueling the machine.

 

10.  If the engine catches fire or in any other emergency 

situation that requires you to free yourself from the 
machine, open the buckle in the waist belt and drop the 
machine backward.

11.  After using blowers and other equipment, CLEAN UP! 

Dispose of debris in trash receptacles.
