Grounding Instructions
This band saw must be
grounded while in use to protect the
operator from electric shock.
In the event of a malfunction or breakdown,
grounding provi des a path of least r esistance f or
electric current to reduce the risk of electric
shock. This tool is equipped with an electric cord
having an equipment-grounding conduc tor and a
grounding plug t hat looks similiar to the plug in
Figure 21. The plug must be inserted into a
matching outlet that is properly installed and
grounded in accordanc e wit h al l loc al codes and
ordinances.
Figure 19
Figure 20
Do not modify the plug pr ovided. If it will not fit
the outlet, hav e the proper outlet installed by a
qualified elec trician.
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.
Figure 21
14
Check with a qualified electrician or service
o
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.
115 Volt Operation
As received from the factory, your bandsaw is
ready to run at 115 volt operation. This
bandsaw, when wired for 115 volt s, is intended
for use on a ci r cuit t hat has an outl et and a pl ug
that looks li ke the one ill ustrated in Fi gure 21. A
temporary adapt er , like the adapt er in Figure 22,
may be used to connect t his plug to a two-pole
receptacle, as shown in Figure 22, if a properly
grounded outlet i s not available. The t emporary
adapter should only be used until a properly
grounded outlet can be installed by a qualified
electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or
tab, extending from the adapter, must be
connected to a permanent ground such as a
properly grounded outlet box, as shown in
Figure 22.
Figure 22
230 Volt Conversion
If 230V, single-phase operation is desired, the
following inst r uc tions must be followed:
1. Disconnect machine from power source.
2. This band saw is supplied with four motor
leads that are connected for 115V
peration, as shown in Figure 23.
Reconnect these f our motor leads for 230V
operation, as shown in Figure 23.
3. The 115V attachm ent pl ug suppli ed with t he
band saw must be repl aced with a UL/CSA
listed plug suitable for 230V operation, as
shown in Figure 24. Contact your local
authorized W MH Tool Group service center
or qualifi ed el ectrician f or proper pr ocedures
to install the plug. The band saw must
comply with all local and national codes
after the 230 volt plug is installed.
4. The band saw with a 230 volt plug should
only be connected to an outlet having the
same configur ation (Figur e 24). No adapter
is availabl e or should be used with t he 230
volt plug.
Figure 23
Important: In all cases (115 or 230 volts),
make certain the receptacle in question is
properly grou nded. I f you are n ot su re, have
a registered el ectrician check the receptacle.
Figure 24
15
Extens ion Cords
Use only three wire extension cords that have
three-prong grounding plugs and three-pole
receptacles that accept the tool’s plug.
Make sure the cord is in good condition, and
heavy enough to carry the current your band
saw will draw. An undersized cord will cause a
drop in line voltage, resulting in loss of power
and overheating. Figure 25 shows the correct
size to use depending on cord length and the
ampere rating on your machine’s nameplate. If
in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
Repair or replace a damaged or worn cord
immediately.
Adjustments
Unplug the machine from the
power source before making any repairs or
adjustments. Failure to comply may cause
serious injury.

interfere with the blade.
2. Open the top wheel cover . Rotate the wheel
forward by hand, and observe the position
of the blade on the wheel - it should be in
the center of the wheel.
3. If adjustment is necessary, l oosen wing nut
(Figure 29), and tighten tracking knob
slightly to move blade toward rear of
machine. Slightly loosening the tracking
knob will cause the blade to track toward the
front of the machi ne.
4. After blade is tracking in the center of the
wheel, tighten the wing nut.

Adjusting Upper Blade Guide
Assembly
1. Disconnect machine from power source.
2. Loosen lock knob (A, Figure 30) and raise
or lower upper blade guide assembly (B,
Figure 30) t o just abov e the material being
cut.
Figure 29

3. Tighten lock knob. Make sure blade gui de
blocks (C, Figure 30) are still flat to the
blade. If adjustment is necessary, loosen
lock knob (A, Figure 30) and rotate
assembly until guide blocks are flat to blade.
4. If movement of the blade guide assembly
seems “stiff ” when being raised or lo wered,
it can be adjusted t o slide more easily. This
is controlled by an internal spring and ball
which provi de varying degrees of resistance
against the guide post. Use the set screw
(D, Figure 30) to adjust the tension of this
spring. To adjust tension on the spring,
loosen knob (A, Figure 30), use a hex
wrench to tighten or loosen set screw (D,
Figure 30) unt il desired tension is reached,
then re-tight en k nob ( A, Figure 30).
Adjusting Blade Guide and Blade
Support Bearing
Blade guard has been
removed for picture clarity. Never operate
the band saw without al l gu ards in pl ace and
in workin g or de r .
1. Disconnect machine from power source.
2. Blade must already be tensioned and
tracking properly.
3. Loosen thumb screws (E, Figure 31) and
move guide blocks (C, Figure 31) as close
to the blade as possible without pinching it.
4. Tighten thumb screws (E, Figure 31).
5. Loosen thumb screw (F, Figure 31) and turn
knurled knob (G, Figure 31) to move the
guide block bracket in or out until the front
edge of the guide block s are just behind the
"gullets" of the saw teeth.
6. Tighten thumb screw (F, Figure 31).
7. The blade support bearing (K, Figure 31)
should be adjusted so that t he back edge of
the blade ov erlaps the front face of the ball
bearing approximately 1/8". To change
position of the bearing, remove screw (L,
Figure 31), and bearing (K, Figure 31).
Loosen thumb screw (H, Figure 31) and
back off knurled knob (J, Figure 31)
completely to rem ov e the bearing shaft.
Figure 31
19
8. Notice the bearing holder on the shaft is
eccentric. Index t he beari ng shaf t to another
position and slide it back in, making sure the
flange on the thumb screw (H, Figure 31)
properly seats int o the groov e of the bearing
shaft. Re-install the bearing and the screw.
Examine the overlap between the bearing
face and the bl ade. Change the positi on of
the bearing shaft until the overlap is
approxim ately 1/8".
9. With the thumb screw (H, Figure 31) still
loosened, adjust the distance from bearing
to blade. Turn k nurled knob (J , Figure 31) t o
move the support beari ng (K, Figure 31) in
or out until the bearing is 1/64" behind the
blade. (NOTE : To set this distance quick ly,
you can place a dol lar bill or piec e of paper
between support bearing and back of
blade.)
10. Tighten thumb screw (H, Figure 31).
11. Repeat procedures 1 through 10 for the
Lower Blade Guide Assem bly .
