Warning!

Use of this product can generate dust, 
mists, and fumes containing chemicals 
known to cause respiratory disease, 
cancer, birth defects, or other reproduc-
tive harm. If you are unfamiliar with the 
risks associated with the particular dust, 
mists or fumes at issue, consult your 
employer, governmental agencies such 
as OSHA and NIOSH and other sources 
on hazardous materials. If the substance 
being blown or vacuumed is a commer-
cial substance, review the material 
safety data sheet for that substance and 
/ or consult the material manufacturer / 
supplier. The state of California and 
some other authorities, for instance, 
have published lists of substances 
known to cause cancer, reproductive 
toxicity, etc.

Control dust, mist and fumes at the 
source where possible. In this regard 
use good work practices and follow the 
recommendations of OSHA / NIOSH 
and occupational and trade associa-
tions. When the inhalation of toxic dust, 
mists and fumes cannot be eliminated, 
the operator and any bystanders should 
always wear a respirator approved by 
NIOSH / MSHA for the substance at 
issue.

Warning!

Dust with silica in its composition may 
contain crystalline silica. Silica is a basic 
component of sand, quartz, brick, clay, 
granite and numerous other minerals 
and rocks, including masonry and con-
crete products. Repeated and / or sub-
stantial inhalation of airborne crystalline 
silica can cause serious or fatal respira-
tory disease, including silicosis. In addi-
tion, the state of California and some 
other authorities have listed respirable 
crystalline silica as a substance known 
to cause cancer. When encountering 
such materials, always follow the re-
spiratory precautions mentioned above.

!

Warning!

Breathing asbestos dust is dangerous 
and can cause severe or fatal injury, re-
spiratory illness or cancer. The use and 
disposal of asbestos containing products 
have been strictly regulated by OSHA 
and the Environmental Protection 
Agency. Do not blow or disturb asbestos 
or asbestos containing products, such 
as asbestos insulation. If you have any 
reason to believe that you might be 
disturbing asbestos, immediately contact 
your employer or a local OSHA 
representative.

Carry the powerhead on your back

Hold control handle firmly in your hand 
and always keep the handle to the right 
side of your body. Make sure you have 
good balance and secure footing.

In an emergency, throw off the blower 

by opening the quick-release fastener 
on the waist strap and slipping out of the 
shoulder straps.

Before using the blower for the first time, 
practice opening the quick-release 
fastener several times so that you know 
how it works.
