Bostitch BRN175A - Flammable Environments and Blind Areas

ENGLISH
4
gasoline, adhesives, mastics, glues or any other
material that is—or the vapors, fumes or byproducts
of which are—flammable, combustible or explosive.
Using the nailer in any such environment could cause
an EXPLOSION resulting in personal injury or death to
user andbystanders.
• Use extra caution when driving fasteners into
existing walls or other blind areas to prevent contact
with hidden objects or person on other side (e.g.,
wires,pipes)

WARNING: When maintaining the tool:
• When working on air tools, note the warnings in
this manual and use extra care when evaluating
problemtools.
Additional Safety Warnings
• Use the BOSTITCH pneumatic tool only for the purpose for
which it wasdesigned.
• Never use this tool in a manner that could cause a fastener
to be directed toward the user or others in the workarea.
• Do not use the tool as ahammer.
• Always carry the tool by the handle. Never carry the tool
by the airhose.
• Do not alter or modify this tool from the original design or
function without approval fromBOSTITCH.
• Always be aware that misuse and improper handling of
this tool can cause injury to yourself andothers.
• Never leave a tool unattended with the air hoseattached.
• Do not operate this tool if it does not contain a legible
WARNINGLABEL.
• Do not continue to use a tool that leaks air or does
not function properly. Notify your nearest BOSTITCH
representative if your tool continues to experience
functionalproblems.
TO PREVENT ACCIDENTAL INJURIES:
• Never place a hand or any other part of the body in nail
discharge area of tool while the air supply isconnected.
• Never point the tool at anyoneelse.
• Never engage inhorseplay.
• Never actuate the tool unless nose is directed at thework.
• Always handle the tool withcare.
• Do not actuate the tool whileloading.
COMPONENTS (FIG. A)

WARNING: Never modify the power tool or any part
of it. Damage or personal injury couldresult.
Refer to Figure A at the beginning of this manual for a
complete list ofcomponents.
Intended Use
Your roofing nailer has been designed for professional
roofingapplications.
Your nailer is a professional powertool.
DO NOT let children come into contact with the tool.
Supervision is required when inexperienced operators use
thistool.
ASSEMBLY AND USAGE PREP
Air Supply and Connections

WARNING: Do not use oxygen, combustible
gases, or bottled gases as a power source for this
tool as tool may explode, possibly causinginjury.
Fittings
Install a male plug on the tool which is free flowing
and which will release air pressure from the tool when
disconnected from the supplysource.
Hoses
Air hoses should have a minimum of 150 p.s.i. (10.6kg/cm
2
)
working pressure rating or 150 percent of the maximum
pressure that could be produced in the air system. The
supply hose should contain a fitting that will provide “quick
disconnecting” from the male plug on thetool.
Supply Source
Use only clean regulated compressed air as a power source
for this tool. NEVER USE OXYGEN, COMBUSTIBLE GASES, OR
BOTTLED GASES, AS A POWER SOURCE FOR THIS TOOL AS
TOOL MAYEXPLODE.
Regulator
A pressure regulator with an operating pressure of
0–125p.s.i. (0 - 8.79 kg/cm
2
) is required to control the
operat ing pressure for safe operation of this tool. Do not
connect this tool to air pressure which can potentially
exceed 200 p.s.i. (14 kg/cm
2
) as tool may fracture or burst,
possibly causinginjury.
Operating Pressure
Do not exceed recommended maximum operating pressure
as tool wear will be greatly increased. The air supply must
be capable of maintaining the operating pressure at the
tool. Pressure drops in the air supply can reduce the tool’s
driving power. Refer to Tool Specifications for setting the
correct operating pressure for thetool.
Filter
Dirt and water in the air supply are major causes of wear in
pneumatic tools. A filter will help get the best performance
and minimize wear of the tool. The filter must have
adequate flow capacity for the specific installation. The
filter has to be kept clean to be effective in providing clean
compressed air to the tool. Consult the manufacturer’s
instructions on proper maintenance of your filter. A dirty
and clogged filter will cause a pressure drop which will
reduce the tool’sperformance.
Lubrication
Frequent, but not excessive, lubrication is required for best
performance. Use Air Tool Lubricant, Mobil Velocite #10, or
equivalent. Do not use detergent oil or additives as these
lubricants will cause accelerated wear to the seals and
bumpers in the tool, resulting in poor tool performance and
frequent tool maintenance. Only a few drops of oil at a time
is necessary inserted into air fitting opening. Too much oil
will only collect inside the tool and will be noticeable in the
exhaustcycle.
