Gast 2567 Series Oilless Vacuum Pumps and Compressors - Manual (Page 3)

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. Vane life will
be drastically reduced if motor is not operating
properly. Vanes can break or be damaged if
motor/pump runs in the wrong direction.
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.
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.

OPERATION
Injury Hazard
Install proper safety guards as needed. Pumps with
glass jars need safety guards to protect against
breaking glass.
Use only recommended air handling parts
acceptable for pressure not less than 70 psi.
Keep fingers and objects away from openings and
rotating parts.
When provided, motor terminal covers must be in
place for safe operation.
Check that coupling guard and shroud are in place
before operating.
Product surfaces may become hot during operation,
allow product surfaces to cool before handling.
Do NOT direct air stream at body. Air stream from
product may contain solid or liquid material that can
result in eye or skin damage, wear proper eye
protection.
Do NOT spray flammable or combustible liquid.
Wear hearing protection. Sound level from motor
may exceed 85 dBA.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
Electrical Shock Hazard
Disconnect electrical power supply cord before
performing maintenance on this product.
If product is hard wired into system, disconnect
electrical power at the circuit breaker or fuse box
before performing maintenance on this product.
Failure to follow these instructions can result in
death, fire or electrical shock.
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 DIAGRAM A)
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.
