IMPORTANT SAFETY
INSTRUCTIONS
INSTRUCTIONS PERTAINING
TO A RISK OF FIRE OR
INJURY TO PERSONS
WARNING – When using tools, basic pre-
cautions should always be followed,
including the following:
General
To reduce the risks of electrica.
shock, re, and injury to persons,
read all the instructions before us-
ing the tool.
Work area

Personal safety
Stay alert. Watch what you are do-a.
ing and use common sense when
operating the tool. Do not use the
tool while tired or under the inu-
ence of drugs, alcohol, or medica-
tion. A moment of inattention while
operating the tool increases the risk
of injury to persons.
Dress properly. Do not wear looseb.
clothing or jewelry. Contain long
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.
Avoid unintentional starting. Bec.
sure the switch is off before con-
necting to the air supply. Do not
carry the tool with your nger on the
switch or connect the tool to the air
supply with the switch on.
Do not overreach. Keep properd.
footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpect-
ed 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 protec-
tion. Wear ANSI-ap-
proved safety goggles.
g. Always wear hearing
protection when using
the tool. Prolonged expo-
sure to high intensity noise is able to
cause hearing loss.
Tool use and care
Use clamps or another practicala.
way to secure and support the
workpiece to a stable platform.
Holding the work by hand or against
the body is unstable and is able to
lead to loss of control.
Do not force the tool.b. 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.
Do not use the tool if the triggerc.
does not turn the tool on or off.
Any tool that cannot be controlled
with the trigger is dangerous and
must be repaired.
Disconnect the tool from the aird.
source before making any adjust-
ments, changing accessories, or
storing the tool. Such preventive
safety measures reduce the risk of
starting the tool unintentionally. Turn
off and detach the air supply, safely
discharge any residual air pressure,
and release the throttle and/or turn
the switch to its off position before
leaving the work area.
Store the tool when it is idle out ofe.
reach of children and other un-
trained persons. A tool is dangerous
in the hands of untrained users.
Maintain the tool with care.f. Keep a
cutting tool sharp and clean. A prop-
erly maintained tool, with sharp cut-
ting edges reduces the risk of binding
and is easier to control.

SKU 98464 For technical questions, please call 1-800-444-3353. Page 4
Check for misalignment or bind-g.
ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-
aged, 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 accessories that areh.
identied by the manufacturer for
the specic tool model. Use of an
accessory not intended for use with
the specic tool model, increases the
risk of injury to persons.
Service
Tool service must be performeda.
only by qualied repair personnel.
When servicing a tool, use onlyb.
identical replacement parts. Use
only authorized parts.
Use only the lubricants suppliedc.
with the tool or specied by the
manufacturer.
Air source
a. Never connect to an air
source that is capable of
exceeding 120 psi for
Items 97526 and 97520
or 100 psi for Item 97524. Over
pressurizing the tool may cause
bursting, abnormal operation, break-
age of the tool or serious injury to
persons. Use only clean, dry, regu-
lated 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.

who have impaired blood circulation
to the hand, past hand injuries, ner-
vous system disorders, diabetes, or
Raynaud’s Disease should not use
this tool. If you feel any medical or
physical symptoms related to vibra-
tion (such as tingling, numbness, and
white or blue ngers), seek medical
advice as soon as possible.
Do not smoke during use. Nico-2.
tine reduces the blood supply to the
hands and ngers, increasing the risk
of vibration-related injury.
Wear suitable gloves to reduce the3.
vibration effects on the user.
Use tools with the lowest vibration4.
when there is a choice between dif-
ferent processes.
Include vibration-free periods each5.
day of work.

1. Incorporate an in-line oiler, shut-off
valve, regulator with pressure gauge,
and lter for best service, as shown in
the diagram above. An in-line shut-
off valve is an important safety
device because it controls the air
supply even if the air hose is rup-
tured.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil to the airline connection be-
fore operation. Add a few more drops
after each hour of continual use.
Attach an air hose to the compres-2.
sor’s air outlet. Connect the air hose
to the air inlet of the tool. Other com-
ponents, such as a connector 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 perfor-
mance, can be hindered by under-
sized air supply components.
The air hose must be long enough3.
to reach the work area with enough
extra length to allow free movement
while working.
Make sure the tool’s throttle or switch4.
is in the off position; refer to Opera-
tion section for description of con-
trols.

TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION:
Release trigger, detach the air
supply, and safely discharge
any residual air pressure in
the tool before performing any
inspection, maintenance, or
cleaning procedures.
TO PREVENT SERIOUS
INJURY FROM TOOL
FAILURE:
Do not use damaged
equipment. If abnormal noise,
vibration, or any leakage is
detected, have the problem
corrected before further use.
Cleaning, Maintenance, and
Lubrication
Anytime any maintenance or re-
pairs are done (including clear-
ing jams), FIRST:
1. Disconnect the Nailer/Stapler from the
air hose.
2. Empty Magazine completely.
3. Attempt to re the Nailer/Stapler into a
piece of scrap wood to ensure that it is
disconnected and is incapable of ring
any staples.
4. Always leave Magazine open dur-
ing maintenance. The Magazine
is spring-loaded and may cause
parts or a fastener to y out of the
Nailer/Stapler.
Clearing Jams for 97526 Pin Nailer
ALWAYS wear1.
ANSI-approved impact safety
goggles when clearing jams.
In case of a fastener jam, take your 2.
nger off the Trigger (27). Rotate the
Trigger Lock/Safety (60) clockwise
or counter-clockwise. For instance,
a “6 o-clock” position will lock the
Trigger (27) and the tool will not re.
However, “3 o-clock” and “9 o-clock”
positions unlock the Trigger (27),
allowing the tool to re.
Note: There is no contact safety for
the Trigger (27). When the Trigger
Lock/Safety (60) is disengaged, the
Nailer will re.
Turn off the air supply and3.
disconnect the Nailer from the
regulator. Open the Nozzle (40) and
clear the jammed fasteners with a
pair of pliers (not included).
If a jam occurs inside the magazine,
depress the upper tip of the Click
Lever (59). The Side Cover (34)
will pop open. If needed, open the
Nozzle (40) to help clear the jam.
Once the jam is cleared, push the
Side Cover (34) back into place and
latch tight using the Click Lever (59).

Maintenance (For All Nailers)
1. Daily - Air Supply Maintenance:
Every day, perform maintenance on
the air supply according to the com-
ponent manufacturers’ instructions.
The lubricator’s oil level needs to be
maintained and the moisture lter
must be regularly drained. Perform-
ing routine maintenance on the air
supply will allow the tool to operate
more safely and will also reduce wear
on the tool.
2. Quarterly (every 3 months) - Tool Dis-
assembly, Cleaning, and Inspection:
Have the internal mechanism
cleaned, inspected, and lubricated by
a qualied technician. If the vanes
need replacement, all vanes should
be replaced as a set.
3. Inspect the air supply Screen that is
located in the End Cap before each
use, and clean or replace as neces-
sary. Dirt and water in the air supply
Screen are major causes of pneu-
matic tool wear. Use a lter in the
compressed air system for better
performance and longer tool life. The
lter must have adequate ow capac-
ity for the specic application.
4. Inspect all of the nuts and screws and
make sure they are securely fas-
tened.
5. Periodically lubricate the Nailer’s driv-
ing mechanism and magazine with
a light oil. Wipe down with a clean
cloth. Never use gasoline or am-
mable solvents to clean the tool.
6. Clean the external parts of the Nailer
with a clean cloth and mild detergent
or non-ammable solvent. Then, dry.
7. Store Nailer in a clean, dry, safe loca-
tion out of reach of children.
If you detect any
air leaks, power
loss, the Nailer/Stapler skips driv-
ing, drives too deep, or not deep
enough, take the Nailer/Stapler to a
qualied service technician.
Please refer to the Troubleshoot-
ing chart on the next page for ad-
ditional maintenance procedures.
