IMPORTANT SAFETY
INSTRUCTIONS
INSTRUCTIONS PERTAINING
TO A RISK OF FIRE,
ELECTRIC SHOCK, OR
INJURY TO PERSONS
WARNING – When using tools, basic
precautions should always be
followed, including the following:
General
a. To reduce the risks of electric
shock, re, and injury to persons,
read all the instructions before
using the tool.
Work area
a. Keep the work area clean and well
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
b. Do not operate the tool in
explosive atmospheres, such as in
the presence of ammable liquids,
gases, or dust. The tool is able to
create sparks resulting in the ignition
of the dust or fumes.
c. Keep bystanders, children, and
visitors away while operating the
tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
a. Stay alert. Watch what you are
doing and use common sense
when operating the tool. Do not
use the tool while tired or under
the inuence of drugs, alcohol, or
medication. A moment of inattention
while operating the tool increases the
risk of injury to persons.

hair. Keep hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
increases the risk of injury to persons
as a result of being caught in moving
parts.
c. Avoid unintentional starting. Be
sure the trigger is released before
connecting to the air supply. Do not
carry the tool with your nger on the
trigger or connect the tool to the air
supply with the trigger pressed.
d. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance
enables better control of the tool in
unexpected situations.
e. Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable
conditions. Wear heavy-duty work
gloves during use.
f. Always wear eye
protection. Wear ANSI-
approved safety goggles

to cause the fastener to be deected
and hit someone, or cause the tool to
react and result in a risk of injury to
persons.
k. WARNING – Remove nger from
the trigger when not driving
fasteners. Never carry the tool with
nger on trigger, the tool is able to re
a fastener.
Tool use and care
a. Use clamps or another practical
way to secure and support the
workpiece to a stable platform.
Holding the work by hand or against
the body is unstable and can lead to
loss of control.
b. Do not force the tool. Use the
correct tool for the application. The
correct tool will do the job better and
safer at the rate for which the tool is
designed.
c. Do not use the tool if the trigger
does not turn the tool on or off.
Any tool that cannot be controlled
with the trigger is dangerous and
must not be used until repaired.
d. Disconnect the tool from the
air 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.
e. Store the tool when it is idle out
of reach of children and other
untrained persons. A tool is
dangerous in the hands of untrained
users.
f. Maintain the tool with care. A
properly maintained tool reduces
the risk of binding and is easier to
control.
g. Check for misalignment or binding
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.
h. Use only accessories that are

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:
1. Anyone using vibrating tools regularly
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.

1. Incorporate a lter, regulator with
pressure gauge, oiler, in-line shutoff
valve, and quick coupler for best
service, as shown in the diagram
above. An in-line shutoff ball
valve is an important safety device
because it controls the air supply
even if the air hose is ruptured.
The shutoff valve should be a ball
valve because it can be closed
quickly.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil into the airline connection
before operation. Add a few more
drops after each hour of continual
use.
2. Attach an air hose to the
compressor’s air outlet. Connect the
air hose to the air inlet of the tool.
Other components, such as a coupler
plug and quick coupler, will make
operation more efcient, but are not
required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION:
Do not install a female quick
coupler on the tool. Such a coupler
contains an air valve that will allow
the air tool to retain pressure and
operate accidentally after the air
supply is disconnected.
Note: Air ow, and therefore tool
performance, can be hindered by
undersized air supply components.
3. The air hose must be long enough
to reach the work area with enough
extra length to allow free movement
while working.
4. Release the tool’s trigger.
5. Close the in-line safety valve between
the compressor and the tool.
6. Turn on the air compressor according
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
7. Adjust the air compressor’s output
regulator so that the air output is
enough to properly power the tool,
but the output will not exceed the
tool’s maximum air pressure at any
time. Adjust the pressure gradually,
while checking the air output gauge
to set the right pressure range.

Page 10 For technical questions, please call 1-800-444-3353. SKU 92917
93253
8. The air pressure setting must
not exceed job site regulations/
restrictions. The air pressure setting
must not exceed 90 PSI when being
used with work pieces that have a
thickness of less than 1-3/4”.
9. Inspect the air connections for leaks.
Repair any leaks found.
10. If the tool will not be used at this time,
turn off and detach the air supply,
safely discharge any residual air
pressure, and release the trigger to
prevent accidental operation.
Note: Residual air pressure should not be
present after the tool is disconnected
from the air supply. However, it is a
good safety measure to attempt to
discharge the tool in a safe fashion
after disconnecting to ensure that the
tool is disconnected and unpowered.

it open during service.
TO PREVENT SERIOUS
INJURY FROM TOOL
FAILURE:
Do not use damaged
equipment. If abnormal noise,
vibration, or leaking air is
detected, have the problem
corrected before further use.
TO PREVENT EXPLOSION:
Lubricate only with specied
lubricants. Lubricate the air
inlet using only pneumatic
tool oil.
Cleaning, Maintenance, and
Lubrication
Note: These procedures are in addition to
the regular checks and maintenance
explained as part of the regular
operation of the air-operated tool.
1. Daily - Air Supply Maintenance:
Every day, perform maintenance
on the air supply according to
the component manufacturers’
instructions. The lubricator’s oil
level needs to be maintained and
the moisture lter must be regularly
drained. Performing routine
maintenance on the air supply will
allow the tool to operate more safely
and will also reduce wear on the tool.

TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION, BEFORE ANY
MAINTENANCE OR REPAIRS
ARE DONE (including clearing
jams):
• Wear ANSI-approved safety
goggles with side shields.
Other people in the work area
must also wear ANSI-approved
impact safety goggles with side
shields.
• Release the trigger.
• Detach the air supply.
• Attempt to re the Tool into
a piece of scrap wood to
ensure that it is disconnected
and is incapable of ring any
fasteners.
• Empty the canister and leave
it open during service.
1. Press down on the Pin (91) and
swing the Door (53) open.
2. If a fastener is jammed in the
discharge area, remove it with pliers.
3. If you are unable to clear the fastener
jam using the method prescribed
above, the tool should be taken to a
qualied service technician for proper
servicing.

sure that air supply is providing enough air
pressure (PSI) to the tool’s air inlet. Do not
exceed maximum air pressure.
3. Lubricate using air tool oil and grease
according to directions.
4. Clean air inlet screen of buildup.
5. Have qualied technician clean and lubricate
mechanism. Install in-line lter in air supply
as stated in Initial Set Up: Air Supply.
Fasteners drive
too deeply.
1. Incorrect tool depth setting.
2. Too much air pressure.
1. Adjust depth setting, if available.
2. Reduce air supply pressure (PSI).
Tool cycles
without ring
fastener.
1. Jammed fastener.
2. Tool empty.
3. Incorrect fasteners used.
4. Canister dirty or not lubricated
properly.
5. Insufcient air ow.
1. Clear jammed fastener according to Clearing
Jams instructions.
2. Fill with correct fasteners.
3. Empty, then ll with correct fasteners.
4. Clean and lubricate canister and pusher.
5. Check for loose connections and make
sure that air supply is providing enough air
ow (CFM) and pressure (PSI) to the tool’s
air inlet. Do not exceed maximum air
pressure.
Frequent
jamming.
Incorrect fastener type. Conrm fastener diameter, type, length, angle,
and collation type. Correct as needed.
