OPERATION
Injury Hazard
Install proper safety guards as needed.
Keep fingers and objects away from openings and
rotating parts.
When provided, motor terminal covers must be in
place for safe operation.
Product surfaces become very hot during operation,
allow product surfaces to cool before handling.
Air stream from product may contain solid or liquid
material that can result in eye or skin damage,
wear proper eye protection.
Wear hearing protection. Sound level from motor
may exceed 70 dBA.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
WARNING
Model with a power supply cord:
This product must be grounded. For either 120-volt or
220/240-volt circuits connect power supply cord
grounding plug to a matching grounded outlet. Do not
use an adapter. (See above diagram.)
Check with a qualified electrician or serviceman if the
grounding instructions are not completely understood,
or if you are not sure whether the product is properly
grounded. Do not modify the plug provided. If it will not
fit the outlet, have the proper outlet installed by a
qualified electrician.
In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an
escape wire for the electric current. This product may
be equipped with a power supply cord having a
grounding wire with an appropriate grounding plug.
The plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.

connectors will differ in shape.
Model that is permanently wired:
This product must be connected to a grounded,
metallic, permanent wiring system, or an equipment
grounding terminal or lead on the product.
Power supply wiring must conform to all required safety
codes and be installed by a qualified person. Check
that supply voltage agrees with that listed on product
nameplate.
Extension cords:
Use only a 3-wire extension cord that has a 3-blade
grounding plug. Connect extension cord plug to a
matching 3-slot receptacle. Do not use an adapter.
Make sure your extension cord is in good condition.
Check that the gage wire of the extension cord is the
correct size wire to carry the current this product will
draw.
An undersized cord is a potential fire hazard, and will
cause a drop in line voltage resulting in loss of power
causing the product to overheat. The following table
indicates the correct size cord for length required and
the ampere rating listed on the product nameplate.
If in
doubt, use the next heavier gage cord. The smaller the
gage number, the heavier the wire gage.

Start Up
If motor fails to start or slows down significantly under
load, shut off and disconnect from power supply. Check
that the voltage is correct for motor and that motor is
turning in the proper direction. Check the plug, cord
and switch for damage. If so equipped, the thermal
protection switch has tripped, the motor can restart after
cooling.
It is your responsibility to operate this product at
recommended pressures or vacuum duties and room
ambient temperatures. Do not start against a vacuum
or pressure load.
