IMPORTANT SAFETY INSTRUCTIONS (FOR ALL TOOLS)

WARNING: When using Electric Tools, basic safety precautions should always be followed to reduce the risk of fire, elec-

tric shock, and personal injury, including the following:

1. KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.

2. CONSIDER WORK AREA ENVIRONMENT. Don't expose power tools to rain. Don't use power tools in damp or wet locations. Keep
work area well lit.

3. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces. For example: pipes, radiators, ranges, refriger-
ator enclosures.

4. KEEP CHILDREN AWAY. All visitors should be kept away from work area. Do not let visitors contact tool or extension cord.

5. STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or locked-up place - out of reach of children.

6. DON'T FORCE TOOL. Itwill do the job better and safer at the rate for which it was intended.

example, don't use circular saw for cutting tree limbs or logs.

8. DRESS PROPERLY. Do not wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves and non-skid footwear
are recommended when working outdoors. Wear protective hair covering to contain long hair.

9. USE SAFETY GLASSES. Also use face or dustmask if cutting operation is dusty.

10. DON'T ABUSE CORD. Never carry tootby cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges.

11. SECURE WORK. Use clamps or a vise to holdwork. It's safer than using your hand and it frees both hands to operate tool.

19. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that isdamaged should be carefully checked to deter-
mine that it will operate properlyand perform its intended function. Check for alignment of moving parts, bindingof moving parts, break-

age of parts, mounting, and any other conditionsthat may affect its operation. A guard or other part that is damaged should be properly

SAVE THESE SAFETY RULES FOR FUTURE USE.

ALWAYS WEAR SAFETY GLASSES

The operation of any power tool can result in foreign objects being thrown intothe eyes, which can result in severe eye injury.
Always wear approved safety glasses or a face shield when working with this tool.

GROUNDING
This tool should be grounded while in use to protect-the operator from

electric shock. The tool is equipped with an approved three-conductor
cord and three-prong grounding type plug to fit the proper grounding

type receptacle, The green (or green and yellow) conductor in the cord

is the grounding wire. Never connect the green (or green and yellow)
wire to a live terminal. Your nailer has a plug like that shown in Figure A.
An adapter, Figures B and C, is available for connecting Figure A plugs
to two-prong receptacles. The green-colored rigid ear, lug, etc., must be
connected to a permanent ground such as a properly grounded outlet

box.

page 2

We recommend that you never disassemble the tool or do any rewinng
in the electncal system. Any such repairs should be performed only by
Sears Service Centers or other qualified service organizations. Should

_o_ be ."Jeterrnined _o make a repair yoursel_ remember that the green

colored wire is the "grounding" wire. Never connect this green wire [o a
"live" terminal. If you replace the plug on the power cord, be sure to con-
nect the green wire only to the grounding (longest) prong on a 3-prong
plug. Never remove the groundmg prong.

NOTE: In the event of a malfunction, return your tool to a Sears Service
Center for repair.

EXTENSION CORDS

Tools that have 3 wire cords requiring grounding must only be used with

extension cords that have 3-prong grounding type plugs and 3-pole

receptacles. Only round jacketed extension cords should be used, and
we recommend that they be listed by Underwriters Laboratories (U.L.). If
the extension will be used outside, the cord must be suitable for outdoor use.
Any cord marked as outdoor (The letters "WA" on the cord jacket indicate a
cord recommended for outdoor use) can also be used for indoor work.

An extension cord must have adequate wire size (AWG or American
Wire Gauge) for safety, and to prevent loss of power and overheating

the smaller the gauge number of the wire, the greater the capacity of the
cable, that is 16 gauge has more calSacity than 18 gauge. When using
more than one extension cord to make up the total length be sure each

individual extension cord contains at least the minimum wire size.

result in one complete cycle;

that is the drive and return
stroke all occurring before it

is possible for the operator to
release the trigger. Make
sure your finger is not on the
tngger when connecting the
tool to power supply.

NOTE: If this tool fails to

SWITCHINTERLOCK

This tool is equipped with a trigger switch interlock so that the tool can-

not be inadvertently actuated. To operate, the tool must be held firmly

against the work and then the trigger swDtchcan be depressed.

DO NOT ATI'EMPT TO OVERRIDE THIS INTERLOCK.

FIGURE 5

DRIVING BRADS

Each pull of the trigger will result in one complete cycle, that is the drive
and return stroke all occurring before it is possible for the operator to
release the trigger. Hold the tool tight against the material as shown in
Figure 5, before pulling the trigger to assure safety and proper driving of

the brad. Hold the nailer firmly with both hands, as shown in Figure 5.

One handed operation may result in poor performance.
NOTE: Drive a few brads in scrap wood to get the "feel" of your Electdc

Brad Nailer before you attempt to do any finished work.
NOTE: Do not rapid fire this tool. Damage to the unit could result.

LEVELER STRIP

Different hardnesses of the material in which you are nailing, will cause
the brads to be driven to different depths. When nailing in soft pine, for

example, the Electric Brad Nailer is quite capable of sinking the brad
heads below the surface of the wood. In order to prevent the brad heads
from sinking into the wood, a Leveler Strip is provided (see Figure 6). To
prevent the brad heads from penetrating too deeply the material into
which you are nailing, pull the Leveler Strip off the Electric Brad Nailer

and reinstall it so that the raised boss shown in Figure 6 is in the front
(where the brads come out).

MAINTENANCE

WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS

Only the components shown on the parts list below are to be replaced
by the customer. To avoid the possibility of alteration or damage to the
system, service should be performed by your nearest Sears Electric

Motor Shop/Specialty repair center. Contact your nearest Sears retail
store.

Avoid using solvents when cleaning plastic parts. Most plastics are sus-
ceptible to various types of commercial solvents and may be damaged
by their use. Use clean clothes to remove dirt, etc.

When electric tools are used on fiberglass boats, sports cars, etc., it has
been found that they are subject to accelerated wear and possible pre-
mature failure, as the fiberglass chips and grindings are highly abrasive
to bearings, brushes, commutator, etc. Consequently, it is not recom-

mended that this tool be used for continuous production work on any

fiberglass material. During any use on fiberglass it is extremely impor-
tant that the tool is cleaned frequently by blowing with an air jet.

CAUTION -- Do not alter, attach special fixture, or redesign parts of this
tool. Also, please follow grounding instructions as explained earlier.

Your Sears merchandise takes on added value when you discover that

Sears has over 2,000 Service Units throughout the country.
IMPORTANT! Your Brad Nailer is designed for use with 1" brads. In

most applications, these are sufficient.
Where paneling is being applied over drywall, a slightly longer brad may

be desirable. For this purpose, 1-1/4" brads are available. (Consult your
Instruction Manual for part number). When nailing through paneling,

drywall, and then studding, these longer brads wdl perform adequately. In
other applications where the brads are to be dnven directly into wood, the
brad heads may protrude slightly above the surface. If this situation anses,

use 1" brads.
