GENERAL SAFETY RULES
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there
are certain hazards involved with the operation of the product. Using the machine with respect and caution will
considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored,
personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards,
goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make
up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop.
If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your
personal safety is your responsibility.
This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not
be modified and/or used for any application other than that for which it was designed. If you have any questions relative
to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should
be performed on the product.

POWER CONNECTIONS
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should
be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the
motor to the power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the
same characteristics as indicated on the machine. All line connections should make good contact. Running on low
voltage will damage the motor.
WARNING: DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
MOTOR SPECIFICATIONS
Your machine is wired for 120 volt, 60 HZ alternating current. Before connecting the machine to the power source,
make sure the switch is in the “OFF” position.

2. Grounded, cord-connected machines intended for use
on a supply circuit having a nominal rating less than 150
volts:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. A, the
machine will have a grounding plug that looks like the plug
illustrated in Fig. A. A temporary adapter, which looks like
the adapter illustrated in Fig. B, may be used to connect
this plug to a matching 2-conductor receptacle as shown
in Fig. B if 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.
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. Whenever
the adapter is used, it must be held in place with a metal
screw.
NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.
WARNING: IN ALL CASES, MAKE CERTAIN THE
RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE HAVE A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
1. All grounded, cord-connected machines:
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 machine is
equipped with an electric cord having an equipmentgrounding 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 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
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 machine is properly
grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as shown in
Fig. A.
Repair or replace damaged or worn cord immediately.
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord
which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When
using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord
will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correct gauge to use
depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier
the cord.
