INTRODUCTION

DOUBLE INSULATION

Double insulation is a concept in safety, in electric power

tools, which eliminates the need for the usual three wire

. grounded power cord and grounded supply system

- Wherever there is electric current in the tool there are two

complete sets of insulation to protect the user All expos-

ed metal parts are isolated from the internal metal motor

components with protecting insulation

IMPORTANT

Servicing of atool with double insulation requires extreme

care and knowledge of the system and should be perform-

ed only by aqualified service technician For service we

suggest you return the tool to your nearest Sears Store for

repair Always use original factory replacement parts

when servicing

iMPORTANT SAFETY INSTRUCTIONS (FOR ALL TOOLS)

WARNING: When using Electric Tools, basic safety precautions should always be followed to

reduce the risk of fire, electric shock, and personal irrjury, including the following:

READ ALL INSTRUCTIONS

19 CHECK DAMAGED PARTS. Before further use of the tool, a

guard or other part that is damaged should be carefully

checked to determine that it will operate properly and perform

its intended function Check for alignment of moving parts,

binding of moving parts, breakage of parts, mounting and any

other conditions that may affect its operation A guard or other

part that is damaged should be properly repaired or replaced

by an authorized service center unless otherwise indicated

elsewhere in this instruction manual Have defective switches

replaced by authorized service center Do not use tool if switch

does not turn it on and off

20 DO NOT OPERATE portable electric tools near flammable

liquids or in gaseous or explosive atmospheres Motors in

these tools normally spark, and the sparks might ignite fumes

1 KEEP HANDS AWAY from cutting area Never reach underneath the material for any reason

2KEEP BLADE SHARP. Dull blades may cause the saw to swerve or stall under pressure

The Dual Speed Reciprocating Saw offers a choice of speeds

for greatly improved cutting rates in various materials Note

that the High-Speed setting is more efficient in softer materials

such as wood, while the Low-Speed is best for cutting metals

MOTOR

Be sure your power supply agrees with the nameplate marking

VOLTS 50/60 Hz or AC ONLY means your tool must be oper-

ated only with Alternating Current and never with Direct Cur-

rent VOLTS DC-60 Hz or AC/DC means your tool may be

operated with either Alternating or Direct Current Voltage

decrease of more than 10% will cause loss of power or over-

heating All tools are factory-tested; if this tool does not oper-

ate, check the power supply

OPERATUON

BLADE CLAMPING

To install blade into saw:

1Loosen set screw

2 Insert blade shank from the front between the reciprocating

shaft and the blade clamp

Locate hole in blade over pin on reciprocating shaft

3 Tighten set screw

If the blade should break off and the shank does not come out

of the clamp, be sure the set screw is loose and eject the shank

with a nail or pointed object

__ SHAFT

_: NOTE: A special pin holds the blade clamp on the reciprocat-

ing shaft to prevent the clamp from coming off when set screw

is loosened

FLUSH-TO CUTTING

The exclusive, compact design of the motor housing and spin_

die housing permits extremely close cutting to floors, corners

and other difficult areas (See below)

Ii I° CAUTION: When sawing in-

to walls, floors or wherever

"live" electrical wires may

be encountered, DO NOT

TOUCH ANY METAL PARTS

OF THE TOOL! Hold the tool

only by the plastic handle and

housing to prevent electric

shock if you saw into a "live"

wire

CAUTION: Always wear eye

protection while operating

this power tool

WOOD CUTTING

Before cutting any type of wood, be sure it is firmly anchored or

clamped to prevent s{ipping Check blade chart for type and

length of blade necessary for best results Place blade lightly

against work to be cut, switch on saw motor and allow it to

obtain maximum speed before applying pressure Always hold

saw firmly with both hands while cutting Whenever possible,

the saw shoe must be held firmly against the material being cut

This will prevent the saw from jumping or vibrating and mini-

mize blade breakage.

1

POCKET CUTTING

The initial step in pocket cutting is to measure the surface area

to be cut and mark clearly with a pencil, chalk or scriber. Insert

pocket cutting blade clamp, and tighten blade clamp securely.

Next, tip the saw backward until the back edge of the shoe is

resting on the work surface_ Now switch motor on, always

permitting blade to attain maximum speed Grip handle stead-

ily and begin a slow, deliberate upward swing with the handle

end of the saw Blade will begin to feed into materiel Always be

sure blade is completely through material before continuing

with pocket cuL

NOTE: In areas where blade visibility is limited, use the edge of

the saw shoe as a guide. Lines for any given cut should be

extended beyond edge o.fcut to be made

METAL CUTTING

This unit hasdifferent metal cutting capacities depending upon

type of blade used and on the metal to be cut. Please check

Blade Chart for better blade selection Usa a finer blade for

ferrous metals and a coarse blade for nonferrous materlals_ In

cutting thin gage sheet metals it is best to clamp wood to both

sides of metal sheet This wilt insure a clean cut without excess

vibration or tearing of metal. Always remember not to force

cutting blade as this reduces blade life and causes costly blade

breakage_

NOTE: It is generally recommended that when cutting metals

you should spread a thin film of oil or other coolant along the

cutting line ahead of the saw cut for easier operation and longer

blade life For cutting aluminum, kerosene is preferred=

MAINTENANCE

WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS

GENERAL

Only the parts shown on parts list, page seven, are intended to

be repaired or replaced by the customer All other parts repre-

sent an important part of the double insulation system and

should be serviced only by a qualified service techician,

Avoid using solvents when cleaning plastic parts Most plastics

are susceptible to various types of commercial solvents and

may be damaged by their use Use clean cloths to remove dirt,

carbon dust, 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 premature failure, as the fiberglass chips and

grindings are highly abrasive to bearings, brushes commuta-

tor, etc Consequently it is not recommended that this tool be

used for continuous production work on any fiberglass mate-

rial During any use on fiberglass it is extremely important that

the tool is cleaned frequently by blowing with an air jet
