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.

120-volt grounded connectors
shown. 220/240-volt grounded
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
Increase pressure:

Check the pressure gauge for

output pressure. Turn the regulator screw in to increase

pressure. Maximum pressure is approximately 100 PSI.

Increase vacuum:

Check the vacuum gauge for

input vacuum. Turn the regulator screw in to increase

vacuum. Maximum vacuum is approximately 25 in. Hg.
Maximum pressure and vacuum cannot be produced at

the same time.
If motor fails to start or slows down significantly under

load, shut off and disconnect from power supply. If the

thermal protection switch has tripped, the motor can

restart after cooling. 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.

It is your responsibility to operate this product at
recommended pressures or vacuum duties and
room ambient temperatures. This pump is designed
to operate up to 25 in. Hg vacuum or 100 PSIG
pressure.
