YOUR MODEL W or F METAL CUTTING BAND SAW
INSTALLATION INSTRUCTIONS
\vuu new \V. I*'. W ells saw has boon carefully designed
and built to give you years of accurate, maintenance-free
venice. In order to insure maximum efficiency, we would
like to suggest that the following installation procedure
hi' curelullv followed.
W hen the machine has boon positioned, SHIM CARE
FULLY to he certain that all four corners are firmly set
to avoid a possible twist or hind in the machine. With a
machinist level check both posts for true vertical. Reshim
if necessary.
Install electrical wiring. Make certain the line voltages
comply with ratings on motors. As motor? are dual volt
age. remove cap from drive motor and check wiring.
Power line should he connected to drive motor switch
only, to terminals LI, L2 and L3 for three phase power,
and a check should he made to determine proper rota
tion of the motor. Blade should travel from the hand
wheel end toward the motor end of the machine. If it is
necessary to reverse the direction, reverse L2 and L3
wires of the power line only.
Check the oil level in the hydraulic system by remov
ing the pipe plug located on end of base directly below
the hand wheel. Oil level should be at top of the filler
pipe with cutting head in the lowered position. CHECK
CAREFULLY, as the pipe elbow' may trap a small
amount of oil and give the appearance of being nearly
full when the reservoir is low. Use any good, clean light
hydraulic oil.
Turn on hydraulic pump motor with knob beside the
hand wheel. If the cutting head docs not raise within 30
seconds, shut the motor off and check oil level and direc
tion of rotation. On a three phase machine the pump
motor can be reversed at the switch by reversing any two
of the three wires rather than opening the base of the
machine and rewiring the motor.
BLADE INSTALLATION
Open both covers on the cutting head. Twist the blade
and push beneath the blade brush and insert into the
guides. Place the blade in the frame and around the
blade wheels. Tighten the wheels enough to pull the
blade out, but leave enough slack so the blade can be
lifted up on the wheels against the flanges. After this is
done, finish tightening. It should be reasonably, but not
excessively tight. If the drive

It is impossible to tighten a blade enough to force a
straight cut if it is overloaded or worn to the point of
losing its set.
OPERATING INSTRUCTIONS
With the cutting head raised and the work clamped in
place, you are ready to begin cutting. The cutting head
is lowered by opening either hand valve. One is located
on the top of the bed at the hand wheel end. the other is
on the side of the bed. Both valves serve the same func
tion . . . determining the rate of speed the cutting head
will descend. The valve

cutting head to automatically raise and stop at any pre
set height. Height is controlled by the adjusting collars
on the control rod located adjacent and parallel to the
frame post. When this valve is not in use the trip block
dog, located on the hydraulic piston rod should be tipped
up to a vertical position to eliminate wear on the valve.
The machine can be set to continuously raise and
lower with the hand valve on the side of the machine.
This is very handy for
The operator can loosen the vise, feed the work forward
against the stop, and reclamp while the cutting head is
continuously recycling. The adjusting collar, located im
mediately below' the lower spring
be raised approximately 1/8". In this position the
head will raise before the blade motor is shut off and is
used when cutting in continuous cycle.
The metering valve, located on the saw guide arm, de
termines the PRESSURE on the saw blade. Its proper
use will result in cutting accuracy, longer blade life, and
higher hourly production. The pressure adjusting nut is
turned down to increase the pressure and up to decrease
pressure. The upper edge of the pressure adjusting nut
will give the operator a reading on relative blade pres
sure. It does not read directly in pounds of pressure, but
permits quick setting to the point .it which the best re
sults are obtained for each type of work. Larger material
will generally use more pressure. On channels, tubing and
other thin walled sections, the metering valve should be
used to determine the pressure through the larger areas.
However, the rate of descent must be restricted for cut
ting thin sections, since there will not be enough area of
contact for the blade. This could cause stripping of
teeth.
Determine the proper blade speed in feet per minute
before beginning the cut. Refer to cutting chart cast in

GUIDE ROLLERS on the blade guides should be
cleaned and oiled with a fairly light oil whenever they
become dry or gummy.
VISE SCREW should be kept clean and greased with a
good grade of medium grease. A few drops of machine
oil should be used on the vise screw bearings.
RING GEAR should not be greased or oiled, as dust and
foreign matter will accumulate that would otherwise
fall free.
HYDRAULIC RESERVOIR ... use a light grade of hy
draulic oil. BE VERY CAREFUL TO KEEP DIRT
OF THE HYDRAULIC SYSTEM to prevent damaging
the pump and valves.
FRAME POSTS should be wiped clean occasionally and
a light machine oil applied.
MOTOR PULLEY should receive a few drops of ma
chine oil monthly through hole drilled in motor mount.
VARIABLE SPEED DRIVE should be run throughout
its entire range once weekly. This will eliminate

ADJUSTING BLADE GUIDES
Accuracy of cut depends on proper adjustment of the
guide bearings. Check the condition for
dency towards sticking. They should be snug to the side
of the blade. When the blade is moved sideways or with
a twisting motion, movement should stop at the bearings
and not be transmitted beyond this point.
They must be loose enough to permit the blade to
in and out freely for blade changes, and for proper func
tioning of the metering valve. The guide bolt with the
locking nut above is on an eccentric. By loosening the
locking nut the bearing can be rotated in or out to de
crease or increase the clearance as desired. When prop
erly positioned, lock bearing in place by tightening the
locking nut. By placing the thumb tightly against the
bearing you should be

When aligning the blade parallel with the bed, the
vise should be set at right angles to the bed. Then check
the blade alignment with the vise by placing a square
against the blade, being careful not to push the blade
out of line. If the blade is not at right angles with the
vise, the lower part of either guide may be moved in or

bolt that holds the guide and guide arm in assembly. This

to lock the guide in position.
Check the blade for vertical alignment by placing a
scale across the bed and against the blade. Check the
clearance both at top and bottom of blade to make cer
tain it is vertical. This can be adjusted by the blade
guide screw which rotates the lower part of the guide.
When properly adjusted, a new blade will cut straight.
As the blade wears, it will have a tendency to cut in or
out. This is easily corrected by periodic adjustments, giv
ing you longer blade life and greater accuracy of cut.

METERING VALVE ADJUSTMENTS
To check this valve, raise the cutting head, then open
either of the hand valves to a point at which the cutting
head descends slowly. (2 or 3 inches a minute.) Place a
screw driver under the valve bearing arm and force up

If it continues to leak after reassembly, it must be

HYDRAULIC SYSTEM ADJUSTMENTS
(See
illustration below)
The hvdraulic system consists of a gear type pump di
rectly connected to the motor. The pump is mounted in
the oil reservoir. The reservoir is filled by removing the
pipe plug located below the hand

tion. The pump forces oil through the check valve into
the lower part of the hydraulic cylinders, which in turn
raises the cutting head. When the motor is shut off, the
check valve prevents oil from backing through the pump,
locking the cutting head in position. If the cutting head
creeps down with the hand valves closed, it is generally
caused bv one or both of the hydraulic cylinder leathers
being worn. This can generally be
detected
by an
exces
sive accumulation of oil film around the top of one or
both evlinders. Most of the accumulation of oil can be
removed from
the
top of the cylinders by running the saw
to its uppermost position, leaving about 3 inches. Allow
the machine to stand overnight with the cutting head
raised. Then lower the cutting head completely, remove
the cylinder caps and check for excessive oil above piston

Stop buttons are provided on each side of the bracket
allowing the rod to travel only the proper distance needed
to operate the switch, and prevent damage.
For use on a repeat cycle or with a bar feed, the bottom
button just below the spring should be raised about J»"
above the bottom fixed button. This will turn the pump
motor on before the blade motor turns off.
