HOWEVER, before attempting any electrical hookup,
you should be certain:
1.
The electrical characteristics of the service
branch match the requirements of the motor.
2.
The service branch is equipped with wires of the
required gauge or size.
3.
The branch circuit intended for the machine is
protected with a time delay fuse or circuit breaker
with rated amperage just slightly greater than the
full load current of the motor.

All electrical service work on
your JET sander should be performed by a
qualified, licensed electrician who is familiar with
all safe standard electrical installation practices
and all applicable electrical codes. This includes
local electrical codes which may affect the
connection and operation of the sander in your
specific manufacturing operation.
6.1 Single-Phase Electrical Hookup
When connecting your machine to single phase
power, you will be connecting to 230 volts. Local
codes may, or may not, permit the use of a plug type
of connection for your machine. Where a plug
connection is permitted, the following installation
practices must be followed:
1.
The plug used must be a grounding type of plug.
That is, on 230-volt single phase connections, the
plug must be a three prong plug with two flat
blades in tandem to carry the current, and a third
round or U-shaped prong for the ground
connection.
2.
The service branch to which the plug is
connected must be a branch with a separate
ground wire so the grounding prong of the plug
can be connected to ground effectively.
Note: Local electrical codes in many jurisdictions
DO NOT ALLOW THE USE OF PLUG TYPE
CONNECTIONS FOR SINGLE PHASE POWER
WHEN THE MACHINE IS USED IN A COMMERCIAL
OR INDUSTRIAL ESTABLISHMENT.
In these cases, you must connect your machine to the
service branch using a hardwired junction box
connection.
machine,
as
shipped.
Motor Rotation
The motor's rotation should result in the belt sander
moving downward and the disc sander rotating
counterclockwise.
Circuit Protection
Where the service branch is protected with a fuse or
circuit breaker that has too high a value to offer
protection to the motor supplied, a fuse or circuit
breaker box should be used at the point where the
machine connection is made, and the time delay fuse
or circuit breaker should be a value just slightly higher
than the maximum load current draw.
7.0 Machine Setup
7.1 Basic Setup
1.
Position the machine where it will be located on
the shop floor. When positioning the machine,
consider the type of work which will be done on it
so you allow sufficient room not only for the
workpieces, but also for service to the machine.
2.
Level the machine by adjusting the 4-foot pad
levelers in or out. Secure the setting by tightening
each hex nut against the stand.
3.
Establish an electrical service connection to the
machine. This will vary according to the model
purchased. ALL ELECTRICAL CONNECTIONS
SHOULD
BE
ELECTRICIAN WHO IS FAMILIAR WITH YOUR
STATE AND LOCAL CODES. Many models of
these machines make use of high voltages which
pose a significant risk of serious injury or DEATH
if proper knowledge and precautions are not
used. Electrical instructions are included in
section 6.0 Electrical connections.
4.
Machines with belts are shipped with the belts in
slack condition. During the electrical hookup
phase of machine setup, the belt will have to be
tightened and checked for tracking. See the Belt
Replacement section for instructions on this
procedure.
7.2 Disc Table Angle Adjustment
1.
Disconnect power to the machine to prevent
accidental start-ups.
2.
Loosen the table locking knobs on either end of
the table.
3.
Using a machinist's square against the table and
disc, set the table at exactly 90° to the disc (See
Figure 1).
4.
Tighten the table locking knobs.
5.
Check the pointer. If it is not exactly on the zero
mark, loosen the pointer attaching screw, adjust
the pointer, and retighten the screw.
6.
Reconnect the power to the machine.
