Moving parts can grab the surface and pull the tool out of your control. 6. Never leave this Air Hammer unattended when it is plugged into an air supply. Turn off the tool, and unplug it from an air supply before leaving. 7. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contains 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 silica 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.) UNPACKING When unpacking, check to make sure that the item is intact and undamaged. If any parts are missing or broken, please call Harbor Freight Tools at the number shown on the cover of this manual as soon as possible. NOTE: READ ALL INSTRUCTIONS BEFORE USING THIS PRODUCT SETUP Figure 1 NOTE: For best service, you should incorporate an oiler, regulator, and in-line filter as shown in Figure 1 above. Hoses, couplers, oilers, regulators and filters are all available at Harbor Freight Tools. If you are not using an automatic oiler system, before operation add a few drops of Pneumatic Tool Oil (not included) to the airline connection. Add a few drops after each hour of continual use. ASSEMBLY INSTRUCTIONS Note: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram on page 8 of this manual. WARNING! Make sure the Power Switch of the tool is in its “OFF” position and that the tool is unplugged from its air supply before making any adjustments to the tool. USE AS AIR HAMMER/CHISEL 1. Insert the Chisel (17) you wish to use through the Spring (16) and into the front of the Cylinder (13). Twist the Spring (16) onto the threaded front of the Cylinder (13). NOTE: When twisting on, exert pressure on the hook at the front of the Spring (16). When twisting off, exert pressure on the hook at the back. Doing so allows for easy on, easy off application. See Figures 2 & 3 131617Figure 2 2. Insert Cylinder (13) over the Plunger (14) and the Valve (15) and carefully twist the Cylinder (13) into the Air Housing (1). Figure 3 1 13 14 15 Front Hook 16 Rear Hook 17 NOTE: The threads inside the Cylinder (13) are plastic. Do not exert too much twisting pressure or they can be damaged. The Cylinder should easily twist into the Housing (1) until snug. See Figures 2 & 3. 3. The Air Hammer is now ready to use as a chisel. 4. To remove, or change chisel heads, simply reverse steps 1 and 2. USE AS A SCALER Figure 48A 7A 6A 5A 4A3A 2A 1A 8A Hex Wrench for Set Screw (included) Figure 4A 1. Insert the Needles (5A) through the holes in the Needle Holder (4A). There are nineteen Needles. Make sure all holes are filled before putting the Needle Holder (4A) through the Spring (3A), the Retainer Clip (2A) and into the Barrel Assembly (1A). Slide one Retainer Ring (8A) around the Needles (5A) and fasten it at the front end of the Barrel Assembly (1A). See Figures 4 & 4A 2. Figure 58A 7A 6A 1A 2A 5AHole for Set ScrewHolding the Barrel Assembly (1A) in one hand with the Needles (5A) pointing downward, insert the Needle Driver (6A), the Screw Cap (7A) and the last Retainer Ring (8A). See Figures 4 & 5 3. The Screw Cap (7A) has a Set Screw that holds it in place. Be very careful NOT to tighten the Set Screw too tightly, snug is good. Otherwise you may damage the plastic threads inside the Screw Cap (7A) causing it to bind or strip some threads. 4. Insert the Barrel Assembly (1A) into the end of the Air Hammer Housing (1) and thread the two parts together. As before do not over tighten, snug is good. 5. The Air Hammer is now ready to be used as a Scaler. OPERATION INSTRUCTIONS 1. With the proper tool attached to the Air Hammer, attach your air supply to the Air Inlet (7) at the base on the Housing (1). Turn on the air supply. Carefully place the tool against the surface of the project you are working with. Make sure the project is in a vise or attached to something that holds it securely so it cannot be moved out of position. 2. Set the Air Regulator (11) located at the base of the Housing (1). Air pressure should not exceed 90 PSI. Test the action of the Air Hammer and adjust the Air Regulator (11) as necessary. 3. Use a light touch on the Trigger (8). Never force the Air Hammer against the surface you are working with. Easy, light pressure works best. WARNING: If the Air Hammer is being used as a Scaler, use a ANSI-approved full face shield and not just safety goggles to protect against Needles that may snap off and could possibly cau...
