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 ques-
tions relative to a particular application, DO NOT use the machine until you have first contacted Delta to deter-
mine if it can or should be performed on the product.

GROUNDING INSTRUCTIONS
THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
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 normal 120-volt circuit
and has a grounded plug that looks like the plug illustrat-
ed in Fig. A.
If a properly grounded outlet is not available, a temporary
adapter, shown in Fig. B, may be used for connecting the
3-prong grounding type plug to a 2-hole receptacle. 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, or the like extending from
the adapter must be connected to a permanent ground
such as a properly grounded outlet box cover. 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.
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 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 ordi-
nances.
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 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 under-
stood, or if in doubt as to whether the tool is properly
grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and 3-hole receptacles that accept
the tool’s plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.
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 3-
prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the unit
to the power line, make sure the switch (s) 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 unit.
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. The full-load current is 5.0 amps.

INTRODUCTION
Model 50-868 Delta Air Cleaner is specifically designed to quietly circulate and filter non-metallic dust
which is generated throughout the work area. The Air Cleaner is furnished with two filters: a disposable
outer filter which filters out larger particles five microns in size, and a secondary filter which captures 91%
of the dust particles of one micron in size (one micron = one millionth of a meter). Because breathing micro-
scopic particles can be a potential health hazard, filtering microscopic dust particles offers a cleaner and
safer environment. This Air Cleaner will filter the air in a room measuring 20’ x 20’ x 8’ either 13, 16, or 18
times an hour, depending on the setting. If desired, multiple units can be used to filter larger areas. The Air
Cleaner is maintenance free. An occasional cleaning and/or replacement of filters is the only required
maintenance. UNPACKING
The Air Cleaner is shipped complete in one shipping container. Carefully unpack the Air Cleaner and all loose
items from the shipping container.
DO NOT LIFT THE AIR CLEANER BY POWER CORD.

EXTENSION CORDS
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
a 3-hole 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. C 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.
