before starting maintenance.
MAINTENANCE
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.
Electrical Shock Hazard
WARNING
Injury Hazard
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.
Clean this product in a well ventilated area.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
WARNING
Check that all external accessories such as relief valves
and gauges are attached to cover and are not damaged
before re-operating product.
Check intake and exhaust filters after first 500 hours of
operation. Clean filters and determine how frequently
filters should be checked during future operation. This
one procedure will help to assure the product’s
performance and service life.
SHUTDOWN PROCEDURES
It is your responsibility to follow proper shutdown
procedures to prevent product damage.
NEVER ADD OIL TO THIS OIL-LESS PUMP.
Proper shutdown procedures must be followed to
prevent pump damage. Failure to do so may result in
premature pump failure. Gast Manufacturing Rocking
Piston Oil-Less Pumps are constructed of ferrous
metals or aluminum which are subject to rust and
corrosion when pumping condensable vapors such as
water. Follow the steps below to assure correct
storage and shutdown between operating periods.
1. Disconnect plumbing.
2. Operate product for at least 5 minutes without
plumbing.
3. Run at maximum vacuum for 10 to 15 minutes.
4. Repeat step 2.
5. Disconnect power supply.
6. Plug open ports to prevent dirt or other
contaminants from entering product.
Gast will NOT guarantee field-rebuilt product
performance. For performance guarantee, the product
must be returned to a Gast Authorized Service Facility.
Service Kit contents vary. Most contain gasket and
filter parts.
SERVICE KIT INSTALLATION
Disconnect electrical power supply cord before
installing Service Kit.
If product is hard wired into system, disconnect
electrical power at the circuit breaker or fuse box
before installing Service Kit.
Vent all air lines to release pressure or vacuum.
Failure to follow these instructions can result in
death, fire or electrical shock.
WARNING
Electrical Shock Hazard
1. Remove filter cover.
2. Remove filters and felt (some filters are held
together with a snap fitting). Clean filters by
washing in a non-petroleum based solvent or soap
and water. After cleaning, dry with compressed air
to make sure all moisture is removed before
reinstalling filters.
3. Reinstall felt and filters.
4. Reinstall cover.
It is your responsibility to:
• Regularly inspect and make necessary repairs to
compressor in order to maintain proper operations.
• Make sure that pressure is released from product
before starting maintenance.
This compressor is oil-less and requires NO
lubrication.

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.

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
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.
