WELLSAW MODEL V-20 HISTORY
The Model V-20 WELLSAW, like other WELLSAWS, is the result of continuous development and refinement. It’s vertical design began
with the Model W-20, introduced in 1976. Drawing on field experience gained over 14 years, WELLSAW decided to launch a re-design
of the vertical saw - the new V-20 - to meet the most difficult operating conditions.
The new design features a 2-speed gear box, variable speed blade drive, all steel construction plus the unique rotating blade guides
which greatly increase the saw’s ability to cut very long pieces.
To field test the new V-20 design, the prototype model was placed in a foundry. It was used to cut gates and runners from sand castings; a rough, abrasive, continuous operation that tested every component’s durability. The best measure of the V-20’s performance is
the fact that the foundry ordered a second V-20.
Today, the WELLSAW V-20 continues to be manufactured to conform to WELLSAW’S recognized high standards of quality and
performance. Each saw must pass a series of final inspection tests, including actual metal cutting operations before it shipped. For
this saw to provide satisfactory service, it is necessary that it be properly installed, operated and maintained. This manual has been
prepared to assist you in carrying out these functions. We urge you to study this manual and follow its suggestions.

TROUBLE SHOOTING
NOTES ON SAWING
PREMATURE DULLING OF BLADE
It is widely recognized that a proficient operator is a key to optimum bandsawing. He makes certain the machine is properly
maintained and adjusted for dependable operation. He carefully
sets up each cutting job to prevent damage to the machine and
obtain the best performance from the equipment.
1.
2.
3.
4.
5.
Feed rate too high or low. Check recommendation.
Blade speed too slow or too fast.
Faulty material; heavy scale, hard spots, etc.
Verify material analysis
If coolant flow is not covering saw teeth, increase coolant
flow rate.
6. If saw is vibrating in cut, reduce a blade speed or increase
feed rate.
7. Chipped or broken tooth may be lodged in cut.
8. “Chip welding” caused by improper feed and speed.
9. Incorrect coolant mixture.
10. Incorrect blade selection.
11. Improper break-in of new blade. New blades should be run
initially with reduced feed pressure for approximately 50 to
100 square inches.
12. Saw blade teeth may be hitting blade guides. Check for
proper blade size.
Experienced blade dealers can be very helpful in selecting the
grade and proper tooth blade for each sawing job. All blades
should be straight, have sharp teeth with uniform set, and be “broken in” at a reduced feed rate to obtain good cutting performance
and blade life.
Every cutting situation has special characteristics requiring some
experimentation to determine which blade, speed and feed rate
will achieve the most satisfactory result. Cutting charts indicate a
good starting point, but must be modified by direct experience if
optimum performance is desired.
Here are some helpful pointers for adjusting speed and feed for
cutting performance.
1.
Make sure the saw is cutting a good chip from the workpiece.
2.
Watch for blue chips or excessive “smoke” indicating heat
in the cut which could damage the blade or work harden the
material being cut.
3.
Watch for excessive vibration or chatter marks on the cut-off
piece indicating possible damage to the saw teeth by “hammering”
4.
Check the cut-off for flatness. A dull blade or excessive feed
will produce a “belly” in the cut.
5.
Inspect the blade for worn, rounded or shiny cutting edges.
avoid force cutting which will allow chips to “weld” to saw
teeth and eventually cause the teeth to be stripped off the
blade.

BLADE TEETH CHIPPING OR RIPPING OUT
1.
When experimenting, start with a slow speed and feed rate.
Gradually increase blade speed and then feed pressure by
small amounts until adverse effects are noted. You can then
set the speed and feed at a reasonable level for continuous
cutting. Remember that blade speed and feed pressure must
be balanced to keep cutting a good chip.

6.
CUTTING TIPS
1.
Select blade and speed for material being cut. Use the
coarsest tooth blade suitable for the workpiece while proving
for at least two teeth cutting at all times. Use fastest suitable
band speed and minimum feed source adequate to produce
good cutting action. Work with work-hardening steels, maintain a steady feed; do not let teeth rub without cutting.
2.
Keep the blade guides as close as possible to the workpiece.
3.
If teeth wear off unusually fast, use a slower band speed.
Incorrect blade speed for material.
Blade tension insufficient.
Back-up bearing may be worn.
Incorrect choice of saw tooth pitch.
Incorrect coolant mixture.
Incorrect feed setting. Increase feed.
Work piece not firmly clamped to vice.
Worn or improperly adjusted saw guides. Check and make
necessary adjustments.
7.
5
Blade pitch too coarse. Use a fine pitch saw blade on thin
work sections.
Improper break-in of new blade. Do not start a new blade in
an old cut.
Work piece not held firmly enough. Clamp work securely.
Introduce cooling if it is not being used.
Faulty material; scale or hard spots.
Blade gullets may be loaded. Use higher viscosity lubricant
or coolant.
Blade speed and feed may need adjustment.
V-20 OPERATION AND MAINTENANCE
OPERATION
READ CAREFULLY
The MODEL V20 METAL CUTTING BAND SAW is designed for
efficient performance. With proper care, it will give you many years
of dependable service. READ THIS MANUAL CAREFULLY BEFORE OPERATING YOUR NEW SAW.
After final assembly, each saw is inspected and tested. No adjustment should be needed.
ROTATING BLADE GUIDES
This saw is equipped with blade guides that can be rotated a full
90° to allow cutting very long materials. To rotate these guides:
1.
Remove the throat plate from the center of the work table.
2.
Loosen the cap screws on both the top and bottom blade guide
mounts.
3.
Rotate the Blade Guide Assemblies to guide the blade into the
desired direction. Tighten the cap screws and re-install the
throat plate. It is not normally necessary to loosen the blade
tension when rotating the guide assemblies.
This manual has been prepared to assist you in the operation and
maintenance of your new saw. If you desire additional information
or assistance, please contact your dealer’s service representative.
Adjust the Blade Guard as close to the work surface as practical to limit the amount of exposed saw blade.
PLACING BLADE ON SAW
BLADE BRUSH
1.
Disconnect electrical supply. Wear gloves and safety goggles
throughout the blade changing operation!
Keep the brush positioned so that the brush bristles contact the
toothed portion of the blade.
2.
Open front cover, swing blade guard aside and move tie-bar at
front bottom of table aside.
TABLE
3.
Hold blade carefully while loosening blade tension screw. Remove blade.
4.
Uncoil new blade. Make certain that blade teeth point in direction of band travel; downward toward the table.
5.
Place new 14’9” blade on band wheels and in saw guides.
The back of the blade should make contact with the back-up
bearing in both upper and lower blade guides and the bearing
on the frame. The frame bearing has a groove in it to help
with proper adjustment. Turn the band wheel by hand to verify proper band tracking on wheels and through and through
blade guides. (When changing blade sizes, adjust both upper
and lower back-up bearings.)
6.
7.
Reposition top and bottom blade guards, and close and latch
covers. Door interlocks prevent saw from being turned on
when doors are open.
Start the saw at slow speed to check proper blade installation
before cutting.
SWITCHES
Always press the stop switch to turn off the saw before opening
the cover, making any adjustment, or performing any maintenance.
Restarting is required after the saw automatically stops from power
interruption (undervoltage protection) or overloading.
BLADE GUIDES
When changing blade sizes, adjust the guides to the blade after it
is installed on the band wheels. The side guides should contact
the blade without galling and be recessed behind the toothed portion of the blade. Each side guide is mounted on an eccentric stud
secured by an Allen screw which provides adjustment for sideways
clearance. Back-up guides are set to contact the back of the blade
for blade tracking on the wheels. If necessary, the back-up bearing
contacts the back of the blade. Be sure that both upper and lower
blade guides are adjusted so that the blade travels in a straight line.
(The work table is adjusted to the blade after the blade is installed
and the guides are properly adjusted).
The top blade guide should always be placed as
close to the workpiece as possible to reduce the amount of exposed blade. Keep all guards on the machine and in position when
the saw is in use.
6
To adjust the angle of the table to the blade, loosen the table pivot
clamp screw under the rear of the table. Pivot the table to the desired angle and tighten the clamp screw.
PULLEYS
A controllable and a spring-loaded pulley are used in conjunction
as a fixed center. These pulleys, when installed with a belt, offer
infinite speed variation.
These pulleys have been permanently lubricated. No additional lubrication is required.
Keep the pulleys and belt clean, dry and free of grease. Sealed
bearings are installed so it is important to keep them free of washing detergents or acid solutions which can cause damage.
Check belt alignment periodically. Also check the set screws holding the pulley to the shafts.
VARIABLE SPEED PULLEY
To increase blade speed, rotate the control handle counter-clockwise. To decrease blade speed, rotate handle clockwise.
The variable speed pulley is provided with mechanical speed stops
on the threaded control stem which limit travel of the pulley. Low
speed is limited by the sprocket. High speed is limited by a stop
on the inside of the pulley face.
Do not force the handwheel against these stops! They are set at
the factory for the full speed range and should not be altered unless modified speed range is desired (See “Adjusting Speed Stops”
which follows.)
Handwheel drag is st at the factory and is intended to prevent
handwheel creep during operation while permitting easy speed adjustment. Should the setting change due to normal wear, simply
tighten the set screw in the thrust nut.
from the gear box to the driven wheel and also allows blades of different sizes to be used without damaging the set of blade teeth.
VARIABLE SPEED DIAL
The Variable Speed Dial has been calibrated to measure blade speed
in Surface Feet Per Minute (SFPM). With the saw motor turned off,
select the desired speed range. High range is from 325 to 3000
SFPM. Low range is from 45 to 400 SFPM.
CHANGING THE TIMING BELT
1.
Loosen the four cap screws holding the gear box mount to release tension on the belt.
2.
Remove the old belt and install the new one.
3.
Moving the saw blade slightly when changing speeds will help engage the gears properly. Always wear gloves when moving the saw
blade to avoid injury.
Adjust tension so the timing belt is tight and re-tighten the cap
screws on the gear box mount.
4.
Check the new belt for tightness after two hours of operation.
Adjust as necessary.
After changing speed ranges, start the saw and check the setting on
the dial. Increase speed by turning the handle clockwise.
MAINTENANCE
To re-calibrate the variable speed dial:
GEAR BOX
1.
With the motor running, turn the handle clockwise until it stops at
the slowest speed setting.
1.
2.
Loosen set screw on back of handle and remove handle.
Periodically check the oil level in the gear box. To do this, remove the pipe plug (part number 63 on Gear Box drawing, page
10). Fill to the level of the opening with 90-weight gear oil as
needed. Re-install plug
3.
Holding dial in your hand, turn handle until the red needle points
to the lowest setting.
2.
Drain and refill the gear box every three years or as needed.
4.
Re-install handle. Tighten set screw.
