• Air tool operators and all others in work area should
always wear safety goggles complying with United States

ANSI Z87.1 to prevent eye injury from fasteners and flying

debris when loading, operating or unloading this tool.

• Never exceed operating pressure of 100 PSI.

• Always keep hands and body away from the fastener dis-
charge area when air supply is connected to tool.

• Always disconnect tool from air supply when servicing or
adjusting tool and when tool is not in use.

• Do not operate when contact trip is not in contact with
work.

• Never load the tool until you are ready to use it.

• Never depress tool trigger when loading.

• Always load with nose of tool pointing away from you and
others.

• Never point tool at yourself or others.

• Never carry tool with trigger depressed.

• Do not use oxygen, combustible gas or high pressure
compressed gas as the air supply for the tool.

• Always use tool at safe distance from other people in work
area.

• Do not attempt to discharge fastener into hard or brittle
materials such as concrete, steel or tile.

• Do not connect female quick-disconnect coupling to tool
side of air line.

• Connect male, free-flow nipple to tool side of air line so
that tool is depressurized when hose is disconnected.

• Do not use a hose swivel with this tool.

• Use Sears recommended fasteners only.

DESCRIPTION

The Craftsman 18 Gauge Brad Nailer drives brads from 3/8"to
1_/4"long. Oilless design eliminates daily oiling and oil stains
on workpiece. Die cast aluminum body with textured grip mini-
mizes operator fatigue. Large capacity, side loading magazine
with positive, quick action latch makes loading easy. Safety
feature disables tool unless contact trip is pressed against
workpiece. Tapered nosepiece provides operator with greater
visibility for precise fastener placement. Rigid nosepiece
reduces jamming. The 18 Gauge Brad Nailer is excellent for
molding, furniture making, and picture framing.

AIR SUPPLY LINE

Refer to Figure 1 (page 3).
° The air tool operates on compressed air at pressures from

60 to 100 PSI.

° Never exceed maximum pressure.
Air Delivery Required: 0.47 SCFM @ 90 PSI

(30 shots per minute).
WARNING: Keep hands and body away from discharge area

of tool when connecting air supply. Always disconnect tool
from air supply when servicing or adjusting tool and when tool

is not in use.
° Air operated tools require clean, dry, compressed air to

ensure top performance, low maintenance and long life.

° Dirt and abrasive materials present in all air lines will

damage tool O-rings, valves and cylinders.

° Moisture will reduce tool performance and life if not

removed from compressed air.

° A filter-regulator system is required and should be located

as close to tool as possible (see Figure 1, page 3). A dis-

tance of less than 15 feet is recommended.

° Keep air filter clean. A dirty filter will reduce the air pressure

to the tool causing a reduction in power and efficiency.

° The air supply system must be able to provide air pressure

of 60 to 100 pounds per square inch at tool.

° All hoses and pipes in the air supply system must be clean

and free of moisture and foreign particles.

° Do not mount swivel connector in air supply line.
° The air pressure should be properly regulated.

* Different workpiece materials and different fastener

lengths will require different operating pressure.

* Be sure all connections in air supply system are sealed to

prevent air loss.

* Never connect a female quick-disconnect coupling to the

tool side of air line connection. A male, free-flow coupling
should be connected to the tool side of air line connection.

LOADING

Refer to Figures 2 & 5 (pages 3 and 6).
WARNING: Disconnect tool from air supply. Always load with

nose of tool pointing away from you and others. Always wear
safety goggles that comply with United States ANSI Z87.1.

NOTE: For best results, use Sears fasteners only.
. Depress latch (Fig. 5, No. 58) and slide magazine cover

(Fig. 5, No. 55) backwards (see Figure 2). Insert fasteners
into magazine. Position fasteners at bottom of magazine

with heads toward top of tool.

. Slide magazine cover forward over magazine until latch

snaps into place, locking magazine cover.

WARNING: The female coupling provides a seal preventing
loss of compressed air from compressor tank when discon-
nected from male coupling. If connected to tool side of air
supply, the female coupling could seal a compressed air
charge in the tool which could discharge if the tool trigger is

actuated.

° The air tool is equipped with a contact trip safety mecha-

nism (see Figure 3) that disables tool unless contact trip is
pushed against work. Hold body firmly and press contact
trip on workpiece where fastener is to be applied. Pull trig-
ger to drive fastener into workpiece.

° The tool can also be operated by holding trigger

depressed and pushing contact trip against workpiece.
This operating procedure provides rapid-fire fastener dri-

ving. Never operate tool unless contact trip is in contact

with workpiece.

° The tool is equipped with a push-button switch that can

change the operating mode from rapid-fire to single fire.
When the red stop button (Fig. 5, No. 30) is pushed in from
the fastener loading side, the tool will fire one fastener only.
Tofire the next fastener, both the trigger (Fig. 5, No. 34)
and the contact trip (Fig. 5, No. 65) must be released.

NAILING OPERATION

Refer to Figures 3 & 5 (pages 3 and 6).
WARNING: Never operate tool unless contact trip is in con-

tact with workpiece. Do not operate tool without fasteners or
damage to tool may result. Never fire fasteners into the air
because fasteners may injure operator or others and damage
to tool may result.

OPERATINGPRESSURE

o Use only enough air pressure to perform the operation. Air

pressure in excess of that which is required will make the
operation inefficient and may cause premature wear or
damage to the tool.

o Determine minimum air pressure required by driving some

test fasteners into the workpiece. Set air pressure so that
test fasteners are driven down flush with the work surface.

Fasteners driven too deep may damage workpiece.

EXHAUST DEFLECTOR
Refer to Figures 4 & 5 (pages 4 and 6).
o Exhaust deflector can be positioned to point in any direc-

tion (full 360 ° movement). Reposition deflector (Fig. 5, No.

2) by grasping firmly and rotating to the desired position.

Refer to Figure 5 (page 6).

MAGAZINE AND PISTON-RAM
° Keep magazine and nose of tool clean and free of any dirt,

lint or abrasive particles.

The tip of the ram (Fig. 5, No. 18) can become dented or
rounded over time.

• Square off the tip of the ram with a clean, fine hand file to
extend the life of the ram and tool. Fastener firing will be
more consistent if the ram tip is kept clean and square.

SAFETY MECHANISM
Inspect contact trip safety mechanism daily for proper opera-

tion. Do not operate tool if mechanism is not operating
properly.

With the red push-button switch in the rapid-fire mode, per-
form the following procedures to test safety mechanism:

• Leave trigger untouched while pushing contact trip into

workpiece. Tool must not fire.

• Pull trigger while contact trip is clear of work and pointed
away from operator and others. Tool must not fire.

• Depress and hold trigger. Push contact trip against work

where fastener is needed. The tool should drive only one
fastener each time the contact trip is pushed against
workpiece.

If contact trip mechanism does not operate properly,
repair tool immediately through Sears Service Center.

Replace any damaged or missing parts. Use the parts list to
order parts.

REBUILD KITS
Rebuild kits are available as spare parts, (see page 7). Tools

should be rebuilt if tool fails to operate properly after extended
use. See troubleshooting to determine required replacement
parts.

Disconnect tool from air supply before attempting repair
or adjustment.

NOTE: When replacing O-rings or cylinder, lubricate with air
tool oil before assembly.
