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, pre-
vent chip accumulation, and keep fi re-fi ghting equip-
ment nearby.
THIS SAW SHOULD BE GROUNDED WHILE IN USE
TO PROTECT THE OPERATOR FROM ELECTRI-
CAL 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 rat-
ing. Replace or repair a damaged or worn cord im-
mediately.
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 connect-
ed 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.
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.
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, mas-
ter 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 jew-
elry to get caught in moving parts. Rubber-soled foot-
wear 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
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 un-
coiled, place in roller guides and between brush-
es, 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 oppo-
site 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.
INSTALLATION, OPERATION and MAINTENANCE
of the No. 5 WELLS METAL CUTTING BANDSAW

SLIDING VISE JAW
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 ther-
mal 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 cir-
cuit has been broken.
Automatic shut-off operates when saw frame contacts
the switch trigger, which is attached to the frame rest.
BELT
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 al-
ways 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.
MAINTENANCE
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 Ad-
juster” (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 bot-
tom between end of square and blade. If out of align-
ment, 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.
Always keep set screws and thumb screws tight.

WHEEL PITCH ADJUSTMENT
Loosen Blade Before Making These Adjustments!
In case the blade runs too low, or off the idler wheel,
adjust the wheel block to which the wheel is mounted.
To do this, loosen the two cap screws marked “1”
one-half turn and tighten two cap screws marked “2”
an equal amount.
To make similar adjustment on drive wheel at motor
end, it is necessary to loosen the two cap screws at
“3”, then make pitch adjustment by loosening two hol-
low head set screws at “4” and tighten two hollow
head set screws at “3”. The four cap screws should
then be tightened to hold motor plate in a rigid and
fast position.
If there is too much pitch on the wheel the blade will
run too high. This will cause the blade to become
distorted and the back of the blade will be rolled over,
also the wheel rim fl ange will show excessive wear.
To correct this condition, loosen two cap screws at
“2”, tighten two cap screws at “1”. Loosen two
cap screws at “4”, then make pitch adjustment by
loosening two hollow headset screws at “3” and
tightening two hollow head set screws at “4”. The
four cap screws should then be tightened to hold
motor plate in a rigid and fast position.
FRAME WEIGHT ADJUSTMENT
Place weight on slide bar at motor end of slide and
remove dash pot, before adjusting frame spring under
motor end, The frame spring should be adjusted
for approximately 10 Ibs. Use slide weight to make
fi nal feed adjustment. The cutting pressure,
which determines the feed, should not be increased
to a point where the blade starts to run sidewise while
cutting. Large stock will stand a heavier feed than
small stock.
BLADE BRUSHES
Brushes should be cleaned frequently in kerosene
and reversed to take advantage of both rows of bris-
tles.
For best results, replace worn, fi lled or sticky brushes
with new ones. In bolting brushes to angles, be sure
wire bristles are bent in same direction blade travels.
LUBRICATION
• The correct and adequate lubrication is a very
important factor in determining the life and serv-
ice to be obtained. It is imperative that all dust and
dirt should be removed before lubricating.
• Keep vise adjusting screw well lubricated with
a medium type of grease.
• The gears in the gear case are lubricated with
a metal penetrating type of grease that will not
channel. A small quantity of this lubricant can be
added through hole in side of gear case when
required.
• The electric motor has sealed-type ball bearings
and should be oiled at regular intervals accord-
ing to standard practices, when repacking, a high
grade medium type of grease should be used.
• Keep internal ring gear and pinion well greased
with a good quality fi ber type grease (medium
grade). For proper inspection and for greasing
these gears, it is necessary to remove the drive
wheel.
• Lubricate the motor pivot post with a few drops of
machine oil. If properly lubricated, the weight of
the motor will keep the belt tight, and allow easy
speed changes.
• Wheel ball bearings are lubricated by pressing
out the bearings and repacking them with a good
quality of ball bearing grease.
Keep machine clean and be sure no cuttings are
allowed to mix with lubricants, as this forms an
abrasive which is detrimental to the operation of
the machine.
Use only hydraulic oil for dash pot.

For Greater Service and Effi ciency
Careful Operation - Blade Consideration
DIFFICULTY REASON REMEDY
Cutting out of line Too heavy a feed or worn blade Reduce feed rate by adjusting frame
weight or replace blade. Replace worn
guide bearings when they begin to show
excessive wear
Guides in wrong position Set as close to work as possible
Guides out of alignment Follow adjustment instructions
Set worn on one side of blade Keep brushes clean. Avoid teeth rub-
bing in cut by applying enough weight so
that each tooth is cutting a good chip
Starting cut on odd shape where
blade does not contact fl at surface Retard feed until blade has a good start
in the material
Stripping teeth Blade teeth too coarse Be sure that two or more blade teeth are
in contact with material being cut
Hard spots on material Rotate stock, if possible. Do not put new
blade in cut at same angle
Breaking Guides out of alignment Follow adjustment instructions.
Blade twisting Adjust guides as close to work as pos-
sible. Be sure material being cut is held
fi rmly
Lack of blade tension Always keep blade tight
Dash Pot malfunction Check hydraulic fl uid level and/or condi-
tion of cup leather
Excessive wear Blade speed too fast. Follow recommended cutting speeds
Blade running off Lack of blade tension Always keep blade tight
wheel
Improper wheel pitch adjustment See instructions for wheel pitch adjust-
ment
Always use a light feed on new blades!
