from work area while operating this tool.
• 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 and unloading this tool
Everyday eyeglasses have only impact resistant lenses.
These are NOT safety glasses. ANSI Z87.1 safety glasses
have permanently attached rigid, hard plastic side shields
and will have "Z87.1" printed or stamped on them.
• Always wear ear protection. The work area may include
exposure to excessive noise levels which will require nec-
essary ear protection. Some environments will require
head protection; use head protection conformingto ANSI
Z89.1.
Do not alter or modify this tool in any way. Do not use this
tool for any application other than for which it was
designed.
Do not use oxygen, carbon dioxide, high-pressure com-
pressed gas or bottled gases as the power source for this
tool. The tool will explode and serious personal injury
could result.
• Never connect the tool to air pressure which could poten-
tially exceed 200 psi. Use onlyclean, dry, regulated air
within rated range as marked on tool.
• The tool must have a male, free-flow hose coupling so that
all air pressure is removed from the tool when the coupling
joint isdisconnected. Failure to use proper coupling could
cause accidental discharge, possibly causing injury.
• Only use air hose that is rated for a maximum working
pressure of 150 psi or 150% of the maximum system pres-
sure, whichever is greater.
Do not use a hose swivel connector with this tool.
Do not pull triggeror depress contact trip while connecting
to the air supply,as the tool may cycle, possiblycausing
injury.
• When loadingtool:Do not pull triggeror depress contact
trip; Do not pointthe tool at yourself or others; Do not
prace hand or any part of body in the fastener discharge
area ofthe tool as accidental actuation may occur and
cause injury.
Disconnect tool from air supply before loadingor unload-
ing, performing tool maintenance, clearing a jammed fas-
tener, leaving work area, moving tool to another location or
handing the tool to another person.
• Use Sears recommended fasteners only.
• Do not load the tool until you are ready to use it.
• Always assume that the tool contains fasteners. Keep the
tool pointed away from yourself and others at all times.
Never engage in horseplay. Never pull the trigger unless
the contact trip is in contact with the workpiece. Keep oth-
ers at a safe distance from the tool while the tool is in
operation,
• Always remove finger from trigger when not drivingfasten-
ers. Never carry the tool with finger on or under the trigger
as accidental actuation may occur and cause injury.
• Always keep hands and body away from the fastener dis-
charge area when air supply is connected to the tool. Grip
tool firmly to maintain control while allowingtool to recoil
away from work surface as fastener is driven. If contact trip
is allowed to recontact work surface before trigger is
released, an unwanted fastener may be driven.
• Check operation of the contact trip frequently. Never use
the tool if the contact trip, trigger or springs have become
inoperable, missing or damaged. Do not alter or remove
contact trip, trigger or springs. Never use a tool that is leak-
ing air, has missing or damaged parts, or requires repair.
• Do not drive fasteners on top of other fasteners or with the
tool at too steep an angle. The fasteners can ricochet and
cause injury. Do not drive fasteners closeto the edge of
the workpiece. The workpiece is likely to split, allowing the
fastener to fly free and cause injury. Do not attempt to
drive fasteners into hard or brittle materials such as con-
crete, steel or tile.
• Do not overreach. Always place yourself in a firmly bal-
anced position when using or handling the tool. Do not
attach the hose or tool to your body.
• Do not operate tool without fasteners or damage to tool
may result.
• Do not use tool without safety warning label. If label is

DANGER: Do not usa oxygen, carbon dioxide, high-pressure
compressed gas or bottled gases as the power sourcefor this
tool.The tool willexplode and serious personal injurycould
result.
• The air tool operates on compressed air at pressures from
70 to 110 PSI.
• Never connect the tool to air pressure which could poten-
tially exceed 200 PSI. Use only clean, dry, regulated air
within rated range as marked on tool,
Air Denvery Required: 2.21 SCFM @ 90 PSI
(30 shotsper minute).
WARNING: Keep hands and body away from discharge area
oftool 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, lubricatedcom-
pressed air to ensure top performance, low maintenance
and long life.
• Dirt and abrasive materials present in all air lines willdam-
age tool O-rings, valves and cylinders.
• Moisture will reduce tool performance and life if not
removed from compressed air.
A filter-regulator-lubricator system is required and shouldbe
located as close to tool as possible.A distance of less than
15 feet is recommended. Lubricator is not required for
oilless tools.
• Keep air filter clean. A dirty filter will reduce the air pressure
tothe tool causing a reduction in powerand efficiency.
• The air supply system must be able to provide air pressure
of 70 to 110 pounds per square inch at tool.
• All hoses and pipes inthe air supply system must be clean
and free of moisture and foreign particles. Hoses must be
rated for a maximum working pressure of 150 PSI or 150%
of maximum system pressure, whichever is greater.
• Do not mount swivel connector in air supplyline.
• 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 couplingto the
tool side of air line connection. A male, free-flow coupling
should be connected to the tool side of air line connection
(see Figure 1).
WARNING: The female couplingprovides a seal preventing
loss of compressed air from compressor tank when discon-
nected from male coupling. If connected to toolside of air
supply,the female coupling could seal a compressed air
charge in the toolwhich could discharge if the tool triggeris
actuated.

WARNING: Read and follow all safety rules and operating
instructionsin thismanual and on warning label oftool before
using this tool. Keep this manual with the tool.
WARNING; Do not use this toolwithout safety warning
label, If label is missing, damaged or unreadable, contact
Sears to obtain a new label.
WARNING; Never operate tool unless contact trip is in con-
tact with wotkpiece. 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.
• Perform =Safety Mechanism Check" as described in the
Maintenance section (see page 6) prior to first use of tool
and on a daily basis thereafter.
• The tool is equipped with a rotating switch that can be set
to rapid-fire or sir_Le-fira mode (see Figure 5). When the
switch is set to single-fire mode, the tool will not drive a
second fastener until the trigger is fully released and
pulled again.
• When the switch is rotated to rapid-fire mode, the tool can
drive fasteners continuously. A fastener will be fired each
time the contact trip is pressed against the workpiece, as
long as the trigger is maintained in the pulled position.
Latch
Figure 3 - Slide Nail Strip Forward
• Grasp pusher housing, depress latch and pull the pusher
housing back until the pusher is completely behind the nail
strip.Then release the latch ar,,dhousing. The housingwill
travel forward and the pusher wW apply pressure to the
nail strip, pushing it into the driving mechanism (see
Figure 4).

Operation Mode
SINGLE-FIRE OPERATION:
• The air tool is equipped with a contact trip safety mecha-
nismthat disables tool unless contact trip is pushed
against work.To drive e fastener hold body firmly and
press contact trip on workpiece where fastener is to be
applied. Pull trigger to drive fastener intoworkpiece. Tofire
a second fastener liftthe tool from the workplace, release
the trigger and then repeat the above sequence.
RAPID-FIRE OPERATION:
• The tool can also be operated by holding trigger
depressed and pushing contacttrip against workpiece.A
fastener will be driven each time the contacttrip is pushed
against the workplace.This operating procedure provides
rapid-firefastener driving. Never operate tool unless con-
tact trip is in contact with workpiece.

WARNING: Allair power fastening tools recoilwhen operat-
ed. This recoil iscaused by rapid driving of the fastener. Tool
may bounce from recoil causinga second unwanted fastener
to be driven. Reduce tool bounce by holding tool firmly in
hand and pressing tool gently against workpiece. Let the tool
do the work, This willallow recoil of tool to bounce tool away
from workpiece preventing the driving of second fastener.
CONTACT TRIP ADJUSTMENT
The contact trip may be adjusted up or down to vary the
depth of the fastener in the workpiece. To adjust, rotate depth
control knob (see Figure 6) to raise or lower contracttrip to
desired setting.

OPERATING PRESSURE
• Use only enough air pressure to performthe operation. Air
pressure in excess of that which is requiredwill make the
operation inefficientand may cause premature wear or
damage to the tool.
• Determine minimum air pressure required by driving some
test fasteners intothe workpiece. Set air pressure so that
test fasteners are driven down flush with the work surface.
Fasteners driven too deep may damage workpiece.
COLD WEATHER OPERATION
CAUTION: Do not store in cold environment. Frostor ice
could form inside tool affectingoperation and damaging tool.
Use a coldtemperature lubricant, such as ethylene glycol,
when operatingtool in freezing temperatures.
Refer to Figure 12 (page 8).
LUBRICATION
Lubricate tool daily with quality air tool oiJ.If no air line lubri-
cator is used, place five or six drops of oil into air inletcap
(Figure 12, Key No. 24).
MAGAZINE AND PISTON-RAM
• Keep magazine and nose oftool clean and free of any dirt,
lintor abrasive particles.
The tip of the ram (Fig. 12, No. 16) 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 wiU be
more consistent if the ram tip is kept clean and square.
SAFETY MECHANISM CHECK
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 switchin the rapid-firemode, per-
form the following procedures to test safety mechanism:
• Leave trigger untouchedwhile pushing contact trip into
workpiece. Tool must not fire.
• Pull trigger while contacttrip isclear of work and pointed
away fromoperator and others. Tool must not fire.
• Depress and hold trigger.Push contact trip against work
where fastener is needed. The toolshould drive onlyone
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 listto
order parts.
REBUILD KITS
Rebuild kits are available as spare parts, (see page 9). Tools
should be rebuiltif toolfails to operate properly after extended
use. See troubleshooting to determine required replacement
parts.
