including the following:

General

a. To reduce the risks of electric

shock, re, and injury to persons,

read all the instructions before us-

ing 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 explo-

sive 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.

tool. Distractions are able to result in

the loss of control of the tool.

Personal safety

a. Stay alert. Watch what you are do-

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.

b. Dress properly. Do not wear loose

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.

c. Avoid unintentional starting. Be

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.

d. Remove adjusting keys and

wrenches before turning the tool

on. A wrench or a key that is left at-

tached to a rotating part of the tool

increases the risk of personal injury.

e. Do not overreach. Keep proper

footing and balance at all times.

Proper footing and balance enables

better control of the tool in unexpect-

ed situations.

f. 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. Wear a full face

shield if you are producing metal

lings or wood chips.

g. Always wear eye protec-

tion. Wear ANSI-ap-

proved safety goggles with

side shields during use.

h. 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

a. Avoid unintentional

misres. Be sure Trigger

(59) is in the OFF posi-

tion when not in use and

before plugging in. Do

not carry any tool with your nger on

the Trigger, whether it is attached to

an air source or not. Do not point tool

towards yourself or anyone whether it

contains nails or not.

b. Do not load nails with Trigger or

safety depressed. Unintentional r-

ing may occur. Always assume Nailer

contains fasteners.

c. Do not load fasteners when Nailer

is connected to air hose. Always

assume tool contains fasteners. Unin-

tentional ring may occur.

d. Properly adjust Nailer angle to

match corresponding fasteners

before inserting nail strip. Failure

to do so can cause Nailer to jam and

lead to personal and/or property dam-

age.

e. Fire nails into an appropriate work

surface only. Do not attempt to re

SKU 98751 For technical questions, please call 1-800-444-3353. Page 4

cleat nails or staples into surfaces

too hard to penetrate. Do not drive

cleat nails or staples on top of other

cleat nails or staples, or at too steep

an angle. Cleat nails and staples can

ricochet, causing personal injury.

Never re this tool into the air or point

it toward yourself or another person.

f. Hold tool away from head and

body during use. Tool may kick

back, causing injury.

g. Do not re fasteners too close to

edge of workpiece. They may split

the workpiece and y free, causing

personal injury.

h. Carry tool safely. Carry tool by

handle.

i. 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 is able to

lead to loss of control.

j. Do not force the tool. Use correct

tool for application. The correct tool

will do the job better and safer at the

rate for which the tool is designed.

k. Disconnect the tool from the air

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

and safely discharge any residual

air pressure before leaving the work

area.

l. Store the tool when it is idle out of

reach of children and other un-

trained persons. A tool is dangerous

in the hands of untrained users.

m. Maintain the tool with care. Keep

tool clean. A properly maintained tool,

reduces the risk of binding and is

easier to control.

n. Check for misalignment or bind-

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.

o. Use only accessories that are

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

a. Tool service must be performed

only by qualied repair personnel.

b. When servicing a tool, use only

identical replacement parts. Use

only authorized parts.

c. Use only the lubricants supplied

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. 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 (70 to

120 PSI). Always verify prior to using

SKU 98751 For technical questions, please call 1-800-444-3353. Page 5

the tool that the air source has been

adjusted to the rated air pressure or

within the rated air-pressure range.

b. Never use oxygen, carbon dioxide,

combustible gases or any bottled

gas as an air source for the tool.

Such gases are capable of explosion

and serious injury to persons.

Specic Safety Instructions

1. The warnings and precautions dis-

cussed in this manual cannot cover

all possible conditions and situations

that may occur. It must be under-

stood by the operator that common

sense and caution are factors which

cannot be built into this product, but

must be supplied by the operator.

2. WARNING: Some dust created by

power sanding, sawing, grinding, drill-

ing, 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 chemi-

cally treated lumber

Your risk from these exposures var-

ies, 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

SKU 98751 For technical questions, please call 1-800-444-3353. Page 6

particles. (California Health & Safety

Code § 25249.5, et seq.)

3. Take caution, as some woods contain

preservatives such as copper chro-

mium arsenate (CCA) which can be

toxic. When nailing these materials,

extra care should be taken to avoid

inhalation and minimize skin contact.

4. WARNING: The brass components

of this product contain lead, a chemi-

cal known to the State of California

to cause birth defects (or other repro-

ductive harm). (California Health &

Safety code § 25249.5, et seq.)

5. Only use with accessories rated to

handle forces exerted by tool during

operation. Other accessories not de-

signed for the forces generated may

break and forcefully launch pieces.

6. Attach all accessories properly to the

tool before connecting the air sup-

ply. A loose accessory may detach or

break during operation.

7. Obey the manual for the air compres-

sor used to power this tool.

8. Install in-line shutoff valve to allow

immediate control over air supply in

emergency, even if hose is ruptured.

9. Do not lay tool down until it has com-

pletely stopped. Moving parts can

grab surface and lead to control loss.

Vibration Precautions

This tool vibrates during use. Re-

peated or long-term exposure to vibra-

tion 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 regu-

larly 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, 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.

2. Do not smoke during use. Nico-

tine reduces the blood supply to the

hands and ngers, increasing the risk

of vibration-related injury.

3. Wear suitable gloves to reduce the

vibration effects on the user.

4. Use tools with the lowest vibration

when there is a choice between dif-

ferent processes.

5. Include vibration-free periods each

day of work.

6. Grip tool as lightly as possible (while

still keeping safe control of it). Let

the tool do the work.

7. To reduce vibration, maintain tool as

explained in this manual. If abnormal

vibration occurs, stop immediately.

Air Supply

TO PREVENT

EXPLOSION:

Use only clean, dry, regulated,

compressed air to power this

tool. Do not use oxygen,

carbon dioxide, combustible

gases, or any other bottled

gas as a power source for this

tool.

1. Connect a regulator valve, an in-line

shut off valve and 1/4” NPT air hose

(all sold separately) to the Quick Con-

nector. Use thread tape on all thread-

ed connections.The air hose must be

long enough to reach the work area

with enough extra length to allow free

movement while working. 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.

See pages 8 and 9 for Air Tool

Setup procedures.

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.

2. Attach an air hose to the compres-

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 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.

3. The air hose must be long enough

to reach the work area with enough

extra length to allow free movement

while working.

4. Close the in-line safety valve be-

tween the compressor and the tool.

5. Turn on the air compressor according

to the manufacturer’s directions and

allow it to build up pressure until it

cycles off.

6. 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.

7. Inspect the air connections for leaks.

Repair any leaks found.

8. If the tool will not be used at this time,

turn off and detach the air supply

and safely discharge any residual air

pressure.

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.
