READ AND UNDERSTAND ALL INSTRUCTIONS

Failure to follow all instructions listed below may result in

electric shock,fire,and/or serious injury.

SAVE THESE INSTRUCTIONS

2. Do not operate electric pumps in explosive atmospheres, such as in the

presence of flammable liquids, gases, or dust. Pumps may create sparks

and arcing, which may ignite the dust or fumes.

3. Keep bystanders, children, and visitors away while operating a Pump.

ELECTRICAL SAFETY

4. Avoid body contact with grounded surfaces such as pipes, radiators,

ranges, and refrigerators. There is an increased risk of electric shock if your

body is grounded.

5. Do not expose Electric Pumps to rain or wet conditions. Water entering a

Pump will increase the risk of electric shock.

6. Do not abuse the Power Cord. Never use the Power Cord to carry the tools

or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,

sharp edges, or moving parts. Replace damaged Power Cords immediately.

Damaged Power Cords increase the risk of electric shock.

7. When operating a power tool outside, use an outdoor extension cord

marked “W-A” or “W”. These extension cords are rated for outdoor use, and

reduce the risk of electric shock.

PERSONAL SAFETY

8. Stay alert. Watch what you are doing, and use common sense when

operating a the Pump. Do not use the Pump while tired or under the

influence of drugs, alcohol, or medication. A moment of inattention while

operating this Pump may result in serious personal injury.

9. Dress properly. Do not wear loose clothing or jewelry. Contain long hair.

Keep your hair, clothing,and gloves away from moving parts. Loose

clothes, jewelry, or long hair can be caught in moving parts.

10. Do not overreach. Keep proper footing and balance at all times. Proper

footing and balance enables better control of the power tool in unexpected

situations.

TOOL USE AND CARE

11. Do not force the Pump. Use the correct Pump for your application. The

correct Pump will do the job better and safer at the rate for which it is designed.

12. Disconnect the Power Cord Plug from the power source before making any

adjustments, changing accessories, or storing the tool. Such preventive

safety measures reduce the risk of starting the Pump accidentally.

13. Store idle Pumps out of reach of children and other untrained persons.

Electric Pumps are dangerous in the hands of untrained users.

SKU 92038 For technical questions, please call 1-800-444-3353. Page 4

14. Maintain Pumps with care. Keep them clean. Do not use a damaged Pump.

Tag damaged Pumps “Do not use” until repaired.

15. Check for, breakage of parts and any other condition that may affect the

Pump’s operation. If damaged, have the Pump serviced before using.

Many accidents are caused by poorly maintained Pumps.

16. Use only accessories that are recommended by the manufacturer for your

model. Accessories that may be suitable for one Pump may become hazardous

when used on another Pump.

SERVICE

17. Pump service must be performed only by qualified repair personnel.

Service or maintenance performed by unqualified personnel could result in a risk

ofinjury.

18. When servicing a Pump, use only identical replacement parts. Follow

instructions in the

“Inspection,Maintenance,And Cleaning”

section of this

manual. Use of unauthorized parts or failure to follow maintenance instructions

may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES

1. Maintain labels and nameplates on the Pump. These carry important

information. If unreadable or missing, contact Harbor FreightTools for a

replacement.

2. Always wear ANSI approved safety impact eye goggles and heavy work

gloves when using the Pump. Using personal safety devices reduce the risk

for injury.Safety impact eye goggles and heavy work gloves are available from

Harbor Freight Tools.

3. Maintain a safe working environment. Keep the work area well lit. Make sure

there is adequate surrounding workspace. Always keep the work area free of

obstructions, grease, oil, trash, and other debris. Do not use an Electric Pump in

areas near flammable chemicals, dusts, and vapors. Do not use this product in a

damp or wet location.

4. Avoid unintentional starting. Make sure you are prepared to begin work

before turning on the Pump.

5. All hydraulic hoses and hydraulic systems to be used with this pump must

be rated at a working pressure of at least 2200 PSI.

6. Never leave the Pump unattended when it is plugged into an electrical

outlet. Turn off the Pump and unplug it from its electrical outlet before leaving.

SKU 92038 For technical questions, please call 1-800-444-3353. Page 5

7. Make sure the OilTank (13) is completely filled with a high quality hydraulic

oil prior to use.

8. This Pump should be mounted in a properly vented area at least 18 inches

above the floor.

WARNING!! Allow 2 seconds between motor starts. Failure to comply may

burn out the motor.

9. Always unplug the Pump from its electrical outlet before performing any

inspection, maintenance, or cleaning procedures.

10. WARNING! People with pacemakers should consult their physician(s)

before using this product. Electromagnetic fields in close proximity to a heart

pacemaker could cause interference to or failure of the pacemaker.

GROUNDING

The Power Cord requires the attachment of a 220 volt, grounded, 3-Prong Plug

(not included). For safety purposes, only a qualified, certified, electrician should

attach a Plug to the Power Cord. Never modify the Plug in any way. To comply with

the National Electric Code, and to provide additional protection from the risk of

electrical shock, this product should only be connected to a 220 volt electrical outlet

that is protected by a Ground Fault Circuit Interrupter (GFCI).

WARNING!

SKU 92038 For technical questions, please call 1-800-444-3353. Page 6

Grounded

tools require a three wire extension cord.

2. As the distance from the supply outlet increases, you must use a heavier gauge

extension cord. Using extension cords with inadequately sized wire causes a

serious drop in voltage, resulting in loss of power and possible tool damage.

(See Figure C, next page.)

3. The smaller the gauge number of the wire, the greater the capacity of the cord.

For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.

(See Figure C.)

4. When using more than one extension cord to make up the total length, make

sure each cord contains at least the minimum wire size required.

(See Figure C.)

5. If you are using one extension cord for more than one tool, add the nameplate

amperes and use the sum to determine the required minimum cord size.

(See Figure C.)

EXTENSION CORDS

6. If you are using an extension cord outdoors, make sure it is marked with the

suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.

7. Make sure your extension cord is properly wired and in good electrical condition.

Always replace a damaged extension cord or have it repaired by a qualified

electrician before using it.

8. Protect your extension cords from sharp objects, excessive heat, and damp or

wet areas.
