BR 45

english / USA

When working with the blower, always 
wrap your fingers tightly around the 
handle, keeping the control handle 
cradled between your thumb and 
forefinger. Keep your hand in this 
position to have your machine under 
control at all times. Make sure your 
control handle is in good condition and 
free of moisture, pitch, oil or grease. 

!

Warning!

To reduce the risk of personal injury, do 
not direct air blast towards bystanders, 
since the high pressure of the air flow 
could injure eyes and could blow small 
objects at great speed. Do not direct air 
blast towards pets.

!

Warning!

Always shut off the engine before 
cleaning or servicing the unit or 
replacing parts. Always disconnect the 
spark plug before performing 
maintenance or accessing movable 
parts.

The blower fan between the air intake 
and output openings rotates whenever 
the engine is running. In order to reduce 
the risk of injury from contact with the 
fan, never operate your unit without a 
properly mounted intake screen and 
blower tube. Never insert any foreign 
object into the air intake or output 
openings of the machine.

Pay attention to the direction of the wind, 
i.e., do not work against the wind. 

To reduce the risk of stumbling and loss 
of control, do not walk backward while 
operating the machine.

MAINTENANCE, REPAIR AND

STORING

Maintenance, replacement, or repair 
of the emission control devices and 
systems may be performed by any 
nonroad engine repair establishment 
or individual. However if you claim 
warranty for a component which has 
not been serviced or maintained pro-
perly or if nonapproved replacement 
parts were used, STIHL may deny 
warranty.

Use only identical STIHL replacement 
parts for maintenance and repair.
Use of parts manufactured by others 
may cause serious or fatal injury.

Follow the maintenance and repair 
instructions in the appropriate section of 
your owner's manual. Refer to the 
maintenance chart at the last pages of 
this manual.

!

Warning!

Always stop the engine and make sure 
that the fan is stopped before doing any 
maintenance or repair work or cleaning 
the blower. Do not attempt any mainten-
ance or repair work not described in
 your owner's manual. Have such work 
performed at your STIHL service shop 
only.

Check fuel filler cap for leaks at regular 
intervals. Use the specified spark plug 
and make sure it and the ignition lead 
are always in good condition.

!

Warning!

A worn or damaged muffler is a fire 
hazard and may cause loss of hearing. 
Check to see that the muffler is in good 
condition. The blower must not be opera-
ted if the muffler is not functioning pro-
perly or has been removed. 

Remember that the risk of forest fires is 
greater in hot weather. Use the spark 
arresting muffler supplied with the unit. 
Never touch a hot muffler or burn will 
result.
