Assembling The Blower - Stihl BR 500 Instruction Manual

!
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.

Warning!
Proper eye protection is a must. Even
though the discharge is directed away
from the operator, ricochets and bounce
backs can occur during blower
operations.
Never operate a blower
unless wearing goggles
or properly fitted safety
glasses with adequate
top and side protection
which comply with
ANSI Z 87.1 (or your applicable national
standard).
Fellow workers must also wear personal
protective equipment.
!
Warning!
Blower noise may damage your hearing.
Wear sound barriers (ear plugs or ear
mufflers) to help protect your hearing.
Continual and regular users should have
their hearing checked regulary.
THE BLOWER
For illustrations and definitions of the
blower parts see the chapter on "Parts
and Controls"!
!
Warning!
Never modify a blower in any way. Only
attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL blower models
are authorized. Although certain
unauthorized attachment are useable for
the STIHL blower, their use may be
extremely dangerous.
!
Warning!
Small particles (e.g. dust) blown through
the blower tubes and nozzle can cause
a static charging of the blower tubes.
This is especially true in low humidity
conditions. In order to reduce the risk of
shock from static charging and
subsequent injury from loss of control,
your blower has features designed to
help reduce the build up of static
electricity in the blower tubes and
equalize the charge with the engine and/
or operator.
For blowers with a non-adjustable
blowing attachment: never operate the
blower without the conductor wire in
place and appropriately mounted as
described in the chapter "Assembling
the Blower – with non-adjustable
blowing attachment".
