SAFETY INSTRUCTIONS

Know your machine,

its safe and proper use!

DISCONNECT POWER before adjusting or servicing

the saw or changing a blade.
STAY CLEAR of all moving parts. Keep hands and

fi ngers away form the saw blade.
WHEN MOVING SAW, with hinged frame (saw head),

secure the head in its down position.
WHEN CUTTING MAGNESIUM, take special precau-

tions. Use a sharp saw blade, make only dry cuts, pre­vent chip accumulation, and keep fi re-fi ghting equip-
ment nearby.

FOR ALL TOOLS

KEEP GUARD IN PLACE and in working order.
REMOVE ADJUSTING KEYS AND WRENCHES.

Form a habit. Check to see that all keys and wrenches
are removed from the tool before turning the tool on.

KEEP WORK AREA CLEAN. Cluttered areas and
benched invite accidents.

THIS SAW SHOULD BE GROUNDED WHILE IN USE
TO PROTECT THE OPERATOR FROM ELECTRI­CAL SHOCK.

CORD CONNECTED TOOLS. If the saw is equipped

with an approved 3-conductor cord and a 3-prong
grounding type plug, it should only be connected to
a properly equipped and grounded receptacle. The
green conductor in the cord is the grounding wire.
Never connect the green wire to a live terminal.

Use only a 3-wire extension cord having a 3-pronged
receptacle, a 3-pronged plug and ample amperage rat­ing. Replace or repair a damaged or worn cord im­mediately.

PERMANENTLY CONNECTED TOOLS. The saw
should be connected to a grounded, metal-enclosed
wiring system or an equipment-grounding conductor
should be run with the circuit conductors and connect­ed to the saw’s grounding terminal or lead.

To reset the manual starter after a power interruption,
return the switch to OFF and press the RESET button
before restarting.

AVOID DANGEROUS ENVIRONMENT. Do not use
power tools in damp or wet locations. Keep your work
area well lighted.

KEEP CHILDREN AWAY. All visitors should be kept a
safe distance from work area.

MAKE WORKSHOP KID-PROOF with padlocks, mas­ter switches, or by removing starter keys form tools.

DON’T FORCE TOOL. It will do the job better and
safer at the rate for which it is designed

USE RIGHT TOOL. Don’t use a tool a or attachment
to do a job for which it was not designed.

WEAR PROPER APPAREL. No loose clothing or jew­elry to get caught in moving parts. Rubber-soled foot­wear is recommended for best footing.

USE SAFETY GLASSES. Also use face or dust mask
if operation is dusty.

SECURE WORK. Use clamps or a vise to hold work.
Provide adequate support to prevent injury from falling
work pieces.

INSTALLATION, OPERATION and MAINTENANCE

of the No. 5 WELLS METAL CUTTING BANDSAW

The No. 5 METAL CUTTING BANDSAW was designed for effi cient performance, and with proper care will
give you many years of dependable service.
Each saw is completely assembled, checked thoroughly and subjected to a test run; no further adjustments
should be necessary.
This manual has been prepared to assist you in the proper installation, operation and maintenance of your
new Wells Metal Cutting Band Saw. If you should desire additional information or assistance, we suggest you
contact your dealer’s service representative.

Read this manual carefully. It was prepared to help you.

INSTALLATION

Upon receipt of machine, uncrate and check all parts.
Report to your carrier any damage to machine and fi le
Proof of Loss Claim with same.

• Place motor in position on motor pivot post and
install V-Belt.

• Be sure motor specifi cations correspond with your
power line.

• Place machine so that each leg is carrying its
share of the load.

Read instructions carefully.

OPERATION

• Do not apply too much feed at fi rst on new
blade.

• Start cut carefully and the blade will last much
longer.

• Make sure all four legs are in solid contact
with the fl oor.

• Keep blade guides as close to both Vise Jaws
as possible.

PLACING BLADE ON SAW

• Raise frame to extreme height.

• Remove blade guard on high side of frame.

• Turn idler band wheel tension screw until the
blade will slide on wheels easily. With blade un­coiled, place in roller guides and between brush­es, then over band wheels.

• Grasp blade on frame side and push toward guide
bracket beam to hold in position, then turn tension

screw until the blade is taut.

• Start motor and tighten blade to proper operating
tension.

• Make certain that the blade teeth point same way
blade is running; if not, this can he accomplished
turning the blade inside out.

AUTOMATIC STOP

When the saw blade has completed the cut through
the material, the saw frame drops on a trigger to
which a rod is attached. This rod passes through
the frame of the machine to the switch on the oppo­site side, and opens the contacts, thereby stopping
the saw.

It will be necessary to raise saw frame clear of the

trigger before machine can he started.

FIXED VISE JAW

The two pins in the fi xed vise jaw should be kept in
place in order to insure square cuts. When cutting
angles, these pins must be removed and the vise
jaws turned to desired position and tightened with
clamp bolts. These pins enable operators to quickly
relocate fi xed vise jaw for 90° cutting. For fi nal

adjustment, the vise jaw should be squared with
the blade.

The sliding vise jaw should be loosened and pushed
against fi xed vise jaw and then tightened.

NEW BLADE TENSIONING DEVICE

On saws equipped with blade tensioning device,
tighten hand wheel tension screw until gauge bar is
fl ush with end of casting.

SLIDING VISE JAW

MAINTENANCE

The sliding vise jaw is equipped with a ratchet and
ratchet dog for quick action and with a hand wheel for
tightening work in vise.

Excessive pressure is not required to hold

material securely in the vise.

MAXIMUM CAPACITY

To obtain maximum vise capacity remove vise jaw
pins and move fi xed vise jaw toward motor end. Make
sure stock in vise will not strike the ratchet arm.

DASH POT

Machines are equipped with a dash pot (frame check)
for the purpose of stabilizing the downward travel of
the saw frame, thereby protecting saw blade from
damage. The action is hydraulic and controlled by
fl ow of fl uid being bypassed through an orifi ce in the
piston on the downward stroke. Only light hydraulic

oil should be used in the cylinder.

SWITCH

A “STOP-START” switch is installed across the line
to protect the wiring and brushes of the motor. A ther­mal coil is provided which breaks the circuit should an
overload occur in the line. The operator should allow
time for coil to cool before trying to start after the cir­cuit has been broken.

Automatic shut-off operates when saw frame contacts
the switch trigger, which is attached to the frame rest.

BLADE GUIDES

The blade guides are arranged to hold the blade in
alignment both vertically and horizontally.

Before making any adjustments, always try a new

blade to be sure that the old blade was not caus-

ing the diffi culty.

To align the blade horizontally, be sure fi xed vise is

square with bed, then square blade with vise. If out of
alignment, loosen one upper set screw In “Roller Ad­juster” (M-92) and tighten opposite set screw, moving
blade in desired direction.

For the vertical alignment, raise frame until blade
just clears bed, then place edge of square on bed with
end against blade being careful not to contact tooth
set. Use feeler gauge not to exceed .002”, adjusting
blade so that feeler gauge will not enter at top or bot­tom between end of square and blade. If out of align­ment, loosen one lower set screw in “Roller Adjuster”
(M-92) and tighten opposite set screw, moving blade
in desired direction. For this vertical alignment, check
blade at both front and rear guides.

Adjust the side roller guides (#100406-001) with
the eccentric axle until both rollers contact blade.
When this adjustment is made, the rollers should be
adjusted so that the path of the blade is straight
and blade is not forced to curve around the rollers.
The back edge of the blade should be even with the
top surface of the side rollers. The top roller guide
(#100406-001) should be in contact with back of blade
at all times.

Usually the weight of the motor holds the belt tight
enough, but in case it does not, the clamp on the
swivel post should be tightened.

SPEED SELECTION

Saws are equipped with step pulleys, which provide a
selection of speed ranges:

• Use the fast speed to cut thin-wall metal, tubing,
thin channels, aluminum, thin brass, or any metal
that will not burn the teeth.

• Use the medium speeds on general cutting such
as cold rolled, machine steels, heavy channels,
etc.

• Use the slow speed for cutting nickel steels or any
metals which require a slow speed on a lathe.

• Use beeswax when cutting brass. Brass should al­ways be cut with a blade which has not previously
cut other metal.

• If teeth wear off unusually fast, use slower speed.
Always keep the blade at proper blade tension
when cutting.

Always keep set screws and thumb screws tight.
