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, extension cords, or air hoses.

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.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. It will do the job better and more safely at the rate for which it was intended. Do not modify this tool and do not use this tool for a purpose for which it was not intended .

6.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.

7.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.

8.Do not overreach. Keep proper footing and balance at all times. Do not reach over or across running machines or air hoses.

9.Maintain tools with care. Keep tools clean for better and safer performance. Follow instructions for lubricating and changing accessories. Inspect tool cords and air hoses 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.

10.Disconnect air supply. Disconnect air hose when not in use.

11.Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are removed from the tool or machine work surface before plugging it in.

12.Avoid unintentional starting. Be sure the switch is in the Off position when not in use and before plugging in. Do not carry any tool with your finger on the trigger, whether it is plugged in or not.

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.

Operation

1/4??? - 18 NPT

Angle

Drill

For best service you should incorporate an oiler, regulator, and inline filter, as shown in the diagram above. Hoses, couplers, oilers, regulators, and filters are all available at Harbor Freight Tools.

1. You will need to prepare a 1/4??? air connector (sold separately) to connect to the

Air Inlet (12) on the Angle Drill. First, wrap the 1/4??? air connector (not included) with pipe thread seal tape before connecting to a 3/8??? ID Air Source Hose (not included). Connect the

Air Source Hose to the Angle Drill.

Note: If you are not using an automatic oiler system, before operation, add a few drops of

Pnuematic Tool Oil to the airline connection. Add a few drops more after each hour of continual use.

2.Set the air pressure on your compressor to 90 PSI. Do not exceed the maximum air pressure of 90 PSI.

3.Check the air connection for leaks.

Operation

Note: This drill can be used to get into hard to reach places with it???s angular configuration. It may also be used just like a traditional drill. This drill does not have a reverse drive. Warning! Always disconnect the unit from the air compressor when changing bits.

Warning! After drilling or driving screws, the bit will be extremely hot. Do not touch it until it has had ample time to cool down.

1.Insert the Chuck Key (44) into one of the holes in the Collet (41) and turn it counterclockwise to open the jaws.

2.Insert the bit and hand tighten it, then tighten it with the Chuck Key (44) by turning it clockwise.

3.With heavy leather gloves on, tug on the bit and make sure it is securely attached. Check that it is straight.

Note: Always use sharp bits. Dull or damaged bits may cause undue stress on the drill and possibly break causing injury. Bits are available at Harbor Freight Tools.

4.Securely clamp your workpiece.

Drilling

5.When drilling wood, place the bit at the point to be drilled. If you are drilling a hard, smooth surface, use a punch to mark the drill location. Grasp the drill firmly with both hands and slowly squeeze the Trigger (3). Never force the tool. Only apply light pressure when horizontal drilling.

Note: For fine tune air adjustment, slowly turn the Nut (9) until you achieve the desired air flow.

Note: When drilling plastics or plastic coated chip board, follow the same directions as stated in number 5 for wood.

Note: If a bit becomes wedged into the workpiece, remove it from the drill and use the appropriate hand tools to remove it.

6.When drilling metal, always use a punch to mark the drilling position. Use a lubricant with most metals, to prolong the life of the bit and increase the drilling action . With steel, tin, and sheet metal use a light machine oil, with aluminum, use paraffin. Do not use lubricants with brass, copper, and cast iron. Grasp the drill firmly with both hands and slowly squeeze the Trigger (3). Never force the tool. Only apply light pressure when horizontal drilling.

7.When driving screws, use bits suitable for the type and size of screw you are using. Drill a pilot hole for the screw head to bite into. Use the lowest torque setting. Grasp the drill firmly with both hands and slowly squeeze the Trigger (3). Never force the tool. To back out a screw, use the appropriate hand tools.

Disconnect the drill from the air compressor while perfoming maintenance.

1.Clean the unit with a damp cloth. Never use solvents to clean the unit.

2.Inspect the chuck and remove any dirt or debris.

3.Periodically oil the hinge on the Trigger (3).

4.Use a grease gun (not included) to add grease to lubricate the Bevel Gear (30) and Bevel Gear (34) through the Grease Cap (43).
