KEEP WORK AREA CLEAN. Clutteredareas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT. Don't use power tools indamp or wet
locations. Keep work area well
lit. Don't expose power tools to rain. Don't use tool
in presence of flammable liquidsor gases.
KEEP CHILDREN AWAY. All visitors should
be kept away from work area. Don't
let visitors contact tool or extensioncord.
STORE IDLE TOOLS. When not
in use, tools should be stored indry, and high or
locked-upplace
- out of reach of children.
DON'T FORCE TOOL.
It will do the job better and safer at the rate for which it
was intended.
USE RIGHT TOOL. Don't force small tool
or attachmenttodo the job of a heavy-
duty tool. Don't use tool for purposenot intended.
DRESS PROPERLY. Don't wear
loose clothingor jewelry. They can be caught in
moving parts. Rubbergloves and non-skidfootwear are recommendedwhen working
outdoors. Wear protectivehair coveringtocontain long hair.
USE SAFETY GLASSES. Also use face or dust mask
if cutting operation is dusty.
DON'T ABUSE CORD. Never carry tool by cord or yank
it todisconnectfrom re-
ceptacle. Keep cordfrom heat, oil, and sharp edges.
SECURE WORK. Use clampsor
a vise to holdwork. It's safer than usingyour hand
and it frees both hands tooperatetool.
DON'T OVERREACH. Keepproperfooting and balance
at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer
performance. Follow instructionsfor lubricating and changing accessories. Inspect
tool cords periodically and
if damaged, have repaired by authorized service facility.
Keep handles dry, clean, and freefrom oil and grease.
DISCONNECT TOOLS. When not inuse, beforeservicing, and when changingacces-
sories, such
as blades, bits, cutters.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see
that keysand adjustingwrenches are removedfrom tool beforeturning it on.
AVOID UNINTENTIONAL STARTING. Don't carry plugged-intool with finger on
switch. Be sure switch
is OFF when plugging in.
OUTDOOR USE EXTENSIONCORDS. When tool
is used outdoors, use only exten-
sioncords intendedfor use outdoorsand
so marked.
STAY ALERT. Watch what you are doing, use common sense. Don't operatetool
when you
are tired.
CHECK DAMAGED PARTS. Before further use of the tool,
a guard or other part
that
is damaged should be carefully checkedtodeterminethat it will operateproper-
ly and perform its intended function. Check for alignmentof moving parts, binding
of moving parts, breakage of parts, mounting, and other conditions that may affect
its operation. A guard or other part thd is damaged should be properly repairedor

replaced by an authorized service center unless otherwise indicatedelsewhere in this
instruction manual. Have defective switches replaced by authorized service center.
Don't use tool if switch does not turn it on and off.
19. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded sur-
faces. Forexample; pipes, radiators, ranges, refrigeratorenclosures.
20. REPLACEMENT PARTS. Whenservicing, use only identicalreplacement parts.
SAVE THESE INSTRUCTIONS.
VOLTAGE WARNING: Before connecting the tool to a power source (receptacle, outlet, etc.) be sure
the voltage
supplied is the seme as that specified on the nameplate of the tool. A power source with
voltage greater thanthat specified
for the tool can result in SERIOUS INJURY to theuser - as well as
damage to the tool.
If in doubt, DO NOT PLUG IN THE TOOL. Using a power source withvoltage
less thanthenameplate rating isharmful to the motor.

How to use
Shear blade inspection
.Be sure tocheck for bladewear beforeoperation. Use of a worn blade results in a ragged
shearingsurface and poor shearingperformance,
so replace blades beforehand.
Blade replacement
.Use the hex wrench provided to remove
the hex socket head bolts securing the
upper and lower blades.
0 Rotate both shear blades 90" (above and
below) to position to unworn portion of
blades. When
all four portions are worn,
of course, the blades should be replaced
with new ones.
.Tighten the hex socket head bolt holding
the upper blade using the hex wrench
provided. Press up on
the shear blade
while doing
so.
-After securing the shear blades, be sure
that there is no gap left between the
inclined surfaces of the shear blade and
the blade holder.

.Then secure the lower shear blade likethe
upper blade, while adjusting the space in
bet ween them.
(Service life of shear blades)
The service life of a shear bladesvaries in
terms of the materials cut, the tensile
strength and the fixed blade clearance.
Roughly speaking,
a bladecan cut about
500 m ((1,500 ft.) of 3.2 mm (1/8") mild
steel; One blade set (upper and lower) is
good for cutting 2,000 m (6,560 ft.).
Adjusting bladeclearance
When performing this adjustment, the
upper blade should be in the lowered
position. First, loosen slightly the hex
socket head bolt securing the lower shear
blade, then insert the thickness gauge
set
for the desired clearance. The cutting
thickness is indicated on the thickness
gauge
so the combinations shown in the
accompanyingtable should be used. Work
the clearance adjust hex socket head bolt
on the yoke until the clearance
is such
that the thickness gauge moves only with
some difficulty. Then carefully secure the
hex socket head bolt and hex nut hold-
ingthe lower blade.

Switch operation
.To start the tool, simply pull the trigger.
Release the trigger to stop. For contin-
uous operation without having to keep
your finger on the trigger, just pull the
trigger and then push in
the lock button
with your thumb. To stop the tool from
the lock position, simply pull the trigger
again and release it.

.The groove on the yoke serves as a thick-

steel plate. If the material fits within the
groove, it is shearable.

.The thickness of materials to be sheared
depends upon the type (strength) of the
material. The maximum shearing thick-
ness
is indicated in the table on the right
in terms of various materials.Attempting
to shear materials thicker than indicated
will result in tool breakdown and/or pos-
sible injury. Keep within the thicknesses
shown
at right.

Maintenance
Replacing carbon brushes
0 Inspect the carbon brushes from time to
time. When they are worn down to about
6 mm (1/4") in length, they will cause
sparking that can lead to
a failure.
