6.6 Electrical connections
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.
1. All Grounded, Cord-connected Tools:
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
This tool is equipped with an electric cord having
an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a
matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a
qualified electrician.
Improper connection of the equipment-grounding
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
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is
necessary, do not connect the equipment-
grounding conductor 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. Failure to comply
may cause serious or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating less
than 150 volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in A, Figure
6. An adapter, shown in Band C, may be used to
connect this plug to a 2-pole receptacle as shown
in Bif a properly grounded outlet is not available.
The temporary adapter should be used only until a
properly grounded outlet can be installed by a
qualified electrician. This adapter is not permitted

9
in Canada. The green-colored rigid ear, lug, and
the like, extending from the adapter must be
connected to a permanent ground such as a
properly grounded outlet box.
3. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
between 150 - 250 volts, inclusive:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in D, Figure
6. The tool has a grounding plug that looks like the
plug illustrated in D. Make sure the tool is
connected to an outlet having the same
configuration as the plug. No adapter is available
or should be used with this tool. If the tool must be
reconnected for use on a different type of electric
circuit, the reconnection should be made by
qualified service personnel; and after reconnection,
the tool should comply with all local codes and
ordinances.
Figure 6
6.7 Voltage conversion
The HVBS-7MW band saw is rated at 115/230V
and comes from the factory prewired at 115V. To
switch to 230V operation, follow the wiring diagram
found on the inside of the motor junction box.
(Similar diagrams are shown in Figures 7/8.) The
plug must be replaced with a plug that is rated at
230V. The coolant pump wiring will have to be
changed also. Follow the diagram found on the
coolant pump head to switch to 230V operation.
Before hooking up to the power source, be sure the
power and coolant switches are in the off position.
Figure 7
Figure 8
6.8 Extension cords
The use of extension cords is discouraged. Try to
position machines within reach of the power
source. If an extension cord becomes necessary,
make sure the cord is in good condition and heavy
enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. Table 1
shows correct size to use depending on cord
length and nameplate ampere rating. If in doubt,
use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

2. Raise bow to vertical position and lock in place
by turning off hydraulic cylinder valve.
3. Loosen hex cap screw (A, Figure 19) and
adjust assembly so that the back roller bearing
is approximately 0.003" to 0.005" from the
back of the blade.
4. Turn nut (B, Figure 19) to adjust the eccentric
bearing snug to the blade. Blade should still
move up and down freely when grasped as in
Figure 20. Warning! Make sure power is
disconnected and hands are protected
before handling blade. Be sure that the
blade teeth do not interfere with the roller
bearings.
5. Repeat for other blade guide assembly.
6. Connect machine to power source.

7.11 Adjusting bow weight
Bow weight is one of the most important
adjustments of the saw. If bow weight is not set
properly, one can expect poor performance,
crooked cuts, tooth stripping, stalling, and the
blade popping off the blade wheels. The hydraulic
feed rate unit will not compensate for improper bow
weight. Bow weight has been set at the factory and
should not need adjustment.
If adjustment becomes necessary:
1. Disconnect machine from power source.
2. Turn on hydraulic cylinder valve and place the
saw bow in horizontal position.
3. Turn feed rate valve on hydraulic cylinder
counter-clockwise until it stops.

14
4. Place a fish-type scale under the blade tension
handle and lift the saw bow. Scale should
indicate approximately 13 to 15 lbs.
5. Adjust tension to approximately 13 to 15 lbs.
by turning bolt (A, Figure 21).
6. Connect machine to power source.
Figure 21
7.12 Adjusting automatic shutoff
The saw should stop after the cut has been
completed:
1. If the saw completes the cut and continues to
run, adjust the trip bracket (A, Figure 22)
down.
2. If the saw shuts off before the cut is complete,
adjust the trip bracket (A, Figure 22) up.
3. If the saw stops cutting but continues to run,
adjust the stop bolt (B, Figure 22).
The saw is properly adjusted when the saw shuts
off just after the blade has finished the cut.
Figure 22
8.0 Operation
Prior to Operation:
1. Check to see that the blade tooth direction
matches the diagram on saw body.
2. Check to see that the blade is properly seated
on the wheels after proper tension has been
applied.
3. Set the blade guide roller bearings snug
against blade. See section 7.10, Adjusting
blade guide bearings, for more detail.
4. Check for a slight clearance between the
backup rollers and the back of the blade.
5. Position both blade guides as close to work as
possible.
6. Select proper speed and feed rate for material
being cut.
7. Material to be cut must be held securely in
vise.
8. Check to see that coolant level is adequate.
9. Do not start a cut on a sharp edge.
10. Keep machine lubricated. See section 9.1,
Lubrication.

9.0 Maintenance
Disconnect machine from
power source before making any repair or
adjustment. Failure to do this may result in
serious personal injury.
1. Keep all surfaces clean and free of rust, slag,
chips, and coolant build-up.
2. Do not use compressed air to clean the band
saw. Compressed air may force chips into the
guide bearings and other critical areas of the
saw.
3. Use a small paint brush or parts cleaning
brush to remove metal particles.
4. Wipe the saw down with a clean, dry cloth and
oil all unpainted surfaces with light machine oil.
5. Keep the blade guides clean and free of metal
chips.
6. Check the guide bearings frequently to make
sure they are properly adjusted and turning
freely.
9.1 Lubrication
Ball bearings on the blade guide assemblies and
the blade wheels are permanently sealed and
require no lubrication.
Lightly lubricate the vise screw with #2 tube
grease.
Change gear box oil after the first 90 days of
operation. Thereafter, change every six months.
To change gear box oil:
1. Disconnect machine from power source.
2. Place saw bow in horizontal position.
3. Remove screws (A, Figure 23) from gear box
and remove cover plate and gasket.
4. Hold a container under the lower right corner
of the gear box with one hand while slowly
raising the saw bow with the other.
5. Place the saw bow in horizontal position again.
Wipe out remaining oil with a rag.
6. Fill the gear box with approximately 3/4 pint of
90 weight gear oil.
7. Replace the gasket and cover. Fasten the
cover with screws.
8. Connect machine to the power source.
Figure 23
9.2 Chip Cleaning Brush
Do not attempt to adjust blade
brush with machine running. Adjust only when
machine’s power cord has been removed from
power source.
It is very important that the blade cleaning brush be
properly adjusted and kept in good working order.
Replace the brush if it becomes damaged or worn
out. Blade life will be shortened severely if the
brush is allowed to go out of adjustment, becomes
damaged, or is worn out.
