Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be followed to reduce

the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Do not use machines or power tools in damp or wet

locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically

powered tools in the presence of flammable gases or liquids.

3. Keep children away. Children must never be allowed in the work area. Do not let

them handle machines, tools, or extension cords.

4. Store idle equipment. When not in use, tools must be stored in a dry location to

inhibit rust. Always lock up tools and keep out of reach of children.

5. Do not force tool. It will do the job better and more safely at the rate for which it was

intended. Do not use inappropriate attachments in an attempt to exceed the tool

capacity.

Page 3SKU 45790

6. Use the right tool for the job. Do not attempt to force a small tool or attachment to do

the work of a larger industrial tool. There are certain applications for which this tool

was designed. Do not modify this tool and do not use this tool for a purpose for which it

was not intended.

7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in

moving parts. Protective, electrically non-conductive clothes and non-skid footwear

are recommended when working. Wear restrictive hair covering to contain long hair.

8. Use eye and ear protection. Always wear ANSI approved impact safety goggles.

Wear a full face shield if you are producing metal filings or wood chips. Wear an ANSI

approved dust mask or respirator when working around metal, wood, and chemical

dusts and mists.

9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or

across running machines.

10. Maintain tools with care. Keep tools sharp and clean for better and safer

performance. Follow instructions for lubricating and changing accessories. Inspect tool

cords periodically and, if damaged, have them repaired by an authorized technician.

The handles must be kept clean, dry, and free from oil and grease at all times.

11. Disconnect power. Unplug charger when not in use.

12. Avoid unintentional starting. Be sure the switch is in the Off position when not in

use. Do not carry any tool with your finger on the trigger.

13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool

when you are tired.

14. Check for damaged parts. Before using any tool, any part that appears damaged

should be carefully checked to determine that it will operate properly and perform its

intended function. Check for alignment and binding of moving parts; any broken parts

or mounting fixtures; and any other condition that may affect proper operation. Any

part that is damaged should be properly repaired or replaced by a qualified

technician. Do not use the tool if any switch does not turn On and Off properly.

14. Replacement parts and accessories. When servicing, use only identical

replacement parts. Use of any other parts will void the warranty. Only use accessories

intended for use with this tool. Approved accessories are available from Harbor

Freight Tools.

15. Do not operate tool if under the influence of alcohol or drugs. Read warning

labels on prescriptions to determine if your judgment or reflexes are impaired while

taking drugs. If there is any doubt, do not operate the tool.

16. Caution: some woods contain perservatives such as copper chromium arsenate

(CCA) which can be toxic. When cutting these materials extra care should be taken to

avoid inhalation and minimize skin contact.

Note: Performance of this tool may vary depending on the battery charge level.

2. Plug the Battery Charger (31) into an electrical outlet.

Verify that the charging indicator light comes on. If it does not come on, check the

power connection or try a different wall outlet. Charge the new battery until the

charging indicator goes off, and the charged indicator comes on. When battery is fully

charged, the charger will automatically shut off.

Note: Avoid damage to the battery by not overcharging, or storing in an area of high tempera-

ture.

3. After charging, unplug the Battery Charger from the electrical outlet.

4. Slide the Battery (25) into the receptacle at the handle-bottom of the drill.

Note: the operation time of a new battery will ramp up as it is properly used and recharged

(minimum of five recharges).

If charging more than one battery, allow the Battery Charger to cool down before reusing.

Operation

Inserting and Removing Drill and Screw Bits

The cordless drill is equipped with a keyless chuck. Follow these steps to insert bit. Refer to

the photo on next page.

1. Hold the Chuck Sleeve firmly while turning the Chuck (29) counterclockwise until the

opening is large enough to accept the drill bit or screw driver bit.

2. Insert bit and turn Chuck clockwise until it is locked on the bit.

3. Reverse procedures to remove a bit.

Drill / Hammer Function

1. To set the hammer function, turn the Impact Clutch (3) completely counterclockwise.

When drilling, you will be able to feel and hear the hammer action.

2. To remove the hammer function, turn the Impact Clutch completely clockwise.

Drill Torque Selector

The Torque Selector (15) dial is indicated by the number 1 through 3; Lowest torque: posi-

tion #1. Highest torque: position #3.

For example, position #1 (low torque) is appropriate for driving screws into wood without

stripping the screw, but would not provide enough torque for drilling. Position #2 and up

(high torque) are appropriate for drilling.

Drill Operation

1. Insert drill or screw bit into the Chuck (29) and hand tighten.

2. Press the Forward/Reverse Switch (26) to desired position.

Right position

: drill or fasten (clockwise).

Left position

: removing fasteners or freeing bits (counterclockwise).

3. Set the two-position Speed Switch (16) for the desired speed.

Position 1 for fast (0 ~ 1500 RPM); Position 2 for slow (0 ~ 450 RPM)

4. Set the Torque Selector (15) to the desired position.

5. Set the Impact Clutch (3) for normal drilling or hammer (impact) drilling.

The impact drill setting (indicated by a hammer symbol) is typically used for drilling

cement or other hard and brittle materials.

6. Press (and hold) the Variable Speed Switch (23) to turn drill On.

This Switch varies the speed depending on how far in it is pressed.

Avoid overloading the drill. Always use sharpened drill bits. Do not apply excessive

pressure to the drill while drilling. If the drill speed drops abnormally, decrease pressure

immediately. If the bit stops abruptly, or the bit becomes stuck, release Switch at once.

Removing Battery

1. Press (and hold) on the Battery Release Button.

2. Slide the Battery out of the Drill handle.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other

construction activites, contain chemicals known [to the State of California] to cause

cancer, birth defects or other reproductive harm. Some examples of these chemicals

are:

• Lead from lead-based paints

• Crystalline cilica from bricks and cement or other masonry products

• Arsenic and chromium from chemically treated lumber

Your risk from these exposures varies, depending on how often you do this type of

work. To reduce your exposure to these chemicals: work in a well ventilated area, and

work with approved safety equipment, such as those dust masks that are specially

designed to filter out microscopic particles. (California Health & Safety Code 25249.5,

et seq. )

Maintenance

1. Keep tools clean by wiping with a damp cloth.

2. Store tools in carrying case when not using, avoiding high temperature storage area.

3. When the battery becomes weak, and the tool loses power, keep the tool turned On

until the battery is completely drained before recharging. This will ensure a full

recharge.

4. Recharge battery monthly when not in use to maintain battery life.

5. Using a rag and light oil, wipe drill bits and other steel parts to keep them from rusting.
