worn cord immediately. Before connecting the motor to the power line, make cert ain the switch is in the OFF
position and be sure that the electric current is of the same characteristics as st amped on the motor nameplate. All line connections should make good cont act. Running on low voltage will damage the motor.
W ARNING: D O N O T EXPOSE THE DUST COLLECTO R TO RAIN O R OPERATETHE MACHINE IN
DAMPLOCATIONS.
M O TO R SPECIFICATIONS
The motor of the Model 50-820 Dust Collector is shipped wired for 120 Volt s. Before connecting the dust
collector to the power source, make cert ain the switch is in the OFF position.
GROUNDING INSTRUCTIONS
W ARNING: THIS TO O L MUST BE GROUNDEDWHILE IN US E TO PROTECT THE OPERATO R FROM
ELECTRIC SHOCK.
This dust collector must be grounded. If it should malfunction or break down, grounding provides a p ath of
least resist ance for electric current to reduce the risk of electric shock. This dust collector is equipped with a
cord having an equipment-grounding conductor and grounding plug. The plug must be inserted into an
appropriate outlet that is properly inst alled and grounded in accordance with all local codes and ordinances.
W ARNING: Improper connection of the equipment-grounding conductor can result in a risk of
electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the out let is properly grounded. Do not modify the plug provided with the dust collector . If it will not fit the outlet, have
a proper outlet inst alled by a qualified electrician.

ADAPTER
This dust collector is for use on a normal 120-volt circuit
and has a grounded plug that looks like the plug illustrat ed in Fig. 16.
If a properly grounded outlet is not available, a temporary
adapter, shown in Fig. 17, may be used for connecting
the 3-prong grounding type plug to a 2-prong recept acle.
The temporary adapter should be used only until a
properly grounded outlet can be inst alled 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 met al screw.
NOTE: In Canada, the use of a temporary adapter is
not permitted by the Canadian Electric Code .

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
recept acle which will accept the tool s plug. When using
an extension cord, be sure to use one heavy enough to
carry the current of the dust collector . An undersized cord
will cause a drop in line volt age resulting in loss of power
and overheating. Fig. 18, shows the correct size to use
depending on cord length. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the cord.
