Grounding Instructions
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
This mac hine m ust be grounded. I n the event of
a malfuncti on or break down, groundi ng prov i des
a path of least resi stance f or electric current to
reduce the ri sk of el ectri c shock.
Improper connection of the equipmentgrounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes, is the equipmentgrounding conductor. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equi pment-grounding c onduc tor to a
live terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded.
Repair or replace a damaged or worn cord
immediately.
Make sure the voltage of your power supply
matches the specif ications on the m otor plate of
the Band Saw. The machine should be
connected to a dedicat ed circuit.

The use of an extension cord is not
recommended for this Band Saw. But if one is
necessary, m ake sure the cord rati ng is suitable
for the am perage listed on t he machine’s m otor
plate. An under size cord will cause a drop in line
voltage resulting in loss of power and
overheating.
Use the chart in Fi gure 4 as a general guide in
choosing the cor rect size cord. If in doubt, use
the next heavi er gauge. The smaller the gauge
number, the heavier the cord.
230 Volt, Three Phase Operation
The three-phase model i s factory wired f or 230
volt, but can be converted to 460 volt if so
desired (see “Co nverti ng From 230 Volt to 460
Volt”). You may either install a plug or “hardwire” the Band Saw direc tly to a control panel.
If you are connect ing a plug, use a proper ULlisted plug suitable for 230 volt operation.

If the Band Sa w is to be hard- wired to a panel ,
make sure a disconnect is available for the
operator. During hard-wiring of the Band Saw,
make sure the fuses hav e been removed or the
breakers have been tripped in the circuit to
which the Band Saw will be connected. Place a
warning placard on the fuse holder or circuit
breaker to prevent it being turned on while the
machine is being wired.
Converting from 230 Volt to 460 Volt
(Three Phase)
To convert from 230 volt to 460 volt:
1. In t he band saw’s electri cal box, change the
setting on the dial of the overload relay
(“FR” on page 42).
2. Rewire the connections to the transformer
(“T2” on page 42).
3. Change the l eads in t he junct ion box on t he
band saw motor.
4. If using a plug, install a proper UL-listed
plug suitable for 460 volt operation.
IMPORTANT: Consult the diagrams on pages
40 and 41 for clarification of each of these
changes on 230V to 460V conversion.
Three-Phase Test Run
After wiring the band saw, you should check that
the wires have been connected properly.
Connect machine t o the power source and turn
it on for an instant to watch the direction of blade
movement.
If the blade runs upward instead of downward,
disconnect machine from power, and switch
any two of t he three leads in t he motor j unction
box (see “Elect ri c al Connec tions”, page 40).
Adjustments
Blade Removal and Installation
Wear leather gloves when
removing or in stalling band saw bl ades. New
blades usuall y come in a coiled position; to
prevent inj ury, hold the blade wi th one hand
while carefully uncoiling it with the other.
1. Disconnect machine from power source.
2. Open t he upper and lower doors, and swing
away the guard (Figur e 5) .
3. Remove the block from the f ront edge of t he
table (Figure 5).
4. Loosen tension on the blade by t urning the
tension handwheel (Figure 6) to the left.
Figure 5
11
5. Remove t he worn blade and instal l the new
d
blade, m aking sure the teeth face downward
where they pass through the slot in the
table.
6. Use the tension handwheel to tighten the
tension on the blade.
7. Proceed with “Blade Tension” and “Blade
Tracking” bef or e oper ating the band saw.
Blade Tension
Rotate blade tension handwheel to the right to
increase tension on the blade, to the left to
ecrease tension o n the blade. Initi ally, set t he
blade tension to c orrespond to the width of your
blade, as indicated on the tension gauge (F igure
6). As you become familiar with the saw, you
may find it necessary to change the blade
tension fr om t he initi al setti ng, depending on t he
width of t he blade as well as the material being
worked.
Keep in mind that too much or too little blade
tension can cause blade breakage and/or poor
cutting performance.
If the band saw is not t o be used f or a period of
time, release tension on the blade – this will
prolong it s life. First make a note of the specifi c
tension setting for that blade. The tension can
then be re-establ ished quickly when operati ons
are resumed.
Blade Tracking
1. Disconnect machine from power source.
Figure 6
2. Open the top blade wheel doors.
3. Move the gear shift lever into neutral
position (str aight down).
4. Move the upper and lower blade guides
away from the blade ( see “Blade Guides”).
5. Rotate upper blade wheel by hand,
observing the position of the blade as it
rides upon the wheel. The blade should
track as near the center of the wheel as
possible.
6. If the blade does not track properly, rotate
the blade trac ki ng knob (Fi gure 6) c loc kwise
to move the blade toward the front of the
wheel (as vi ewed from the front of the saw)
or counterclockwise to move the blade
toward the rear of the wheel. NOTE: This
will also move the blade away from or
toward the stoppers on the blade guide
assemblies, as shown i n Figure 7.
IMPORTANT: These are sensitive
adjustments; make them gradually and
allow the blade tim e to reac t t o the changes.
Figure 7
12
7. When satisfied, return the upper and lower
blade guides cl ose to the blade.
8. Close upper and lower doors.
Guide Post
For effective c utting and for safety’s sake, ther e
should be a mi nim um amount of space between
the top of the workpiece and the bot tom of the
blade guides. Loosen the locking knob (see
Figure 6) and r otate the handwheel ( Fi gure 6) t o
raise or lower t he guide post so that the gui des
clear the workpiece by about 3/16”.
Blade Guides
Blade guides must be
properly adjusted or damage may occur to
the blade and/o r guides.
1. Loosen the t wo socket head cap screws on
the guide housing. See Figure 8.
2. Move the guide support forward or
backward in accordance with the width of
the blade. The front end of the blade guides
should be adjusted approximately 1/8”
behind the blade teet h. S ee Figure 8.
3. Tighten the hex cap scr ews securel y .
4. This procedure should be done for both
upper and lower guide housings.
5. Loosen t he socket head cap scre ws (Figur e
9) on the blade guides.
6. Mov e the bl ade guides so they are as close
to the blade as possible without touching it.
7. Ti ghten the socket head c ap screws (Fi gure
9).
Figure 8
Figure 9
8. This procedure should be done for both
upper and lower blade gui des.
As the blade guides receive use, they will
become worn at the front end. If the blade
guides become diff icult to adjust, switch the left
and right blade guides (Figure 10).
The stopper posit ioned behi nd the back edge of
the blade (Figure 10) will also become worn with
use, and the friction of the shaft with the saw
blade may cause lines in the surface of the
stopper. If this occurs, loosen the socket head
cap screw, and rot ate the stopper to ei ther side
to change its position on the blade. Re-tighten
socket head cap screw.
Figure 10
13
Squaring Work Table with Blade
1. Place the table in horizontal posi ti on with “0”
on the scale (Figur e 11) .
2. Pl ace a machini st’s square on the tabl e and
against the blade as shown.
3. If the square i s not fl ush against the blade,
loosen the screw below the table (Figur e 11)
with a 26mm wrench (provided).
4. Tilt the table as needed until the square is
flush with bl ade. Reti ghten the screw.
5. Make sure the pointer is set at “0” on the
scale. If it needs slight adjustment, loosen
the screw and shif t the pointer until it ali gns
with “0”. Re-tighten the screw.
Auxiliary Table
1. After the main work table has been set
perpendicular to the blade, use a straight
edge to confirm that the auxiliary table is
level with the main tabl e, as sho wn in Figure
12. If the auxil iary table is not l evel with the
main table, make adjustments as follows.
Figure 11
2. To til t the auxili ary table left or right, loosen
the screws (A, Figure 12) and turn one of
the stops (B, Figure 12) as needed. Retighten screws (A, Figure 12) securely af ter
adjustment.
