injury to persons.
Use only those fasteners listed in the i.
Specications chart of this manual.
Fasteners not identied for use with this
tool by the tool manufacturer are able to
result in a risk of injury to persons or tool
damage when used in this tool.
Service
Tool service must be performed only a.
by qualied repair personnel.
When servicing a tool, use only b.
identical replacement parts. Use only
authorized parts.
Disconnect the tool from the air d.
source before making adjustments,
doing tool maintenance, clearing
jams, touching the safety nosepiece,
leaving work area, loading, or
unloading the tool. Such precautionary
measures reduce the risk of injury to
persons.
Store the tool when it is idle out of e.
reach of children and other untrained
persons. A tool is dangerous in the
hands of untrained users.
Maintain the tool with care.f. A properly
maintained tool reduces the risk of
binding and is easier to control.
Check for misalignment or binding g.
of moving parts, breakage of parts,
and any other condition that affects
the tool’s operation. If damaged,
have the tool serviced before using.
Many accidents are caused by poorly
maintained tools. There is a risk of
bursting if the tool is damaged.
Use only the lubricants supplied c.
with the tool or specied by the
manufacturer.
Air source
a. Never connect to an air
source that is capable of
exceeding 200 PSI. Over
pressurizing the tool may
cause bursting, abnormal operation,
breakage of the tool or serious injury to
persons. Use only clean, dry, regulated
compressed air at the rated pressure or
within the rated pressure range as
marked on the tool. Always verify prior to
using the tool that the air source has
been adjusted to the rated air pressure
or within the rated air-pressure range.
Never use oxygen, carbon dioxide, b.
combustible gases or any bottled gas
as an air source for the tool. Such
gases are capable of explosion and
serious injury to persons.
Use only accessories that are h.
identied by the manufacturer for
the specic tool model. Use of an

when:
Unattended.a.
Fire fasteners into an appropriate 15.
work surface only. Do not attempt to
re fasteners into surfaces too hard to
penetrate. Do not drive fasteners on top
of other fasteners, or at too steep of an
angle. Fasteners can ricochet causing
personal injury.
Do not re fasteners too close to the 16.
edge of a workpiece. They may split the
workpiece and y free, causing personal
injury.
Keep clear of the workpiece near the 17.
area being fastened. Fasteners may
bend sideways during ring, causing
them to exit the workpiece at an
unexpected point, causing personal
injury.
Transport Tool safely. Always disconnect 18.
air supply when moving the tool. Carry
the tool by the handle and avoid contact
with the trigger.
Hold tool away from head and body. 19.
During operation the Tool may kick back
causing injury.
Do not re fasteners into a workpiece 20.
that has people, utility lines, or other
objects behind or inside it.
Keep balance while using this tool. 21.
Keep area below clear if working in
an elevated location, and secure air
hose to prevent falls from bystanders
accidentally pulling on it.
Obey the manual for the air compressor 22.
used to power this tool.
Install an in-line shutoff valve to allow 23.
immediate control over the air supply
in an emergency, even if a hose is
ruptured.
Vibration Precautions
This tool vibrates during use. Repeated
or long-term exposure to vibration may cause
temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration-related injury:
Do not engrave or stamp anything into 24.
the housing to prevent weakening of the
housing.
WARNING: Some dust created by 25.
power sanding, sawing, grinding,
drilling, and other construction activities,
contains chemicals known [to the State
of California] to cause cancer, birth
defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and
cement or other masonry products
• Arsenic and chromium from chemically
treated lumber
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to
these chemicals: work in a well ventilated
area, and work with approved safety
equipment, such as those dust masks
that are specially designed to lter out
microscopic particles. (California Health
& Safety Code § 25249.5, et seq.)
WARNING: The brass components of 26.
this product contain lead, a chemical
known to the State of California to cause
birth defects (or other reproductive
harm). (California Health & Safety code
§ 25249.5, et seq.)
The warnings and precautions discussed 27.
in this manual cannot cover all possible
conditions and situations that may occur.
It must be understood by the operator
that common sense and caution are
factors which cannot be built into this
product, but must be supplied by the
operator.
Anyone using vibrating tools regularly 1.
or for an extended period should rst
be examined by a doctor and then have
regular medical check-ups to ensure
medical problems are not being caused
or worsened from use. Pregnant
women or people who have impaired
blood circulation to the hand, past hand
injuries, nervous system disorders,
diabetes, or Raynaud’s Disease
should not use this tool. If you feel any
symptoms related to vibration (such as
tingling, numbness, and white or blue
ngers), seek medical advice as soon as
possible.
Do not smoke during use. Nicotine 2.
reduces the blood supply to the hands
and ngers, increasing the risk of
vibration-related injury.
Wear suitable gloves to reduce the 3.
vibration effects on the user.
Use tools with the lowest vibration when 4.
there is a choice between different
processes.
Include vibration-free periods each day 5.
of work.
Grip tool as lightly as possible (while still 6.
keeping safe control of it). Let the tool
do the work.
To reduce vibration, maintain tool as 7.
explained in this manual. If abnormal
vibration occurs, stop immediately.
