Page 3: Warning: Safety Precautions
Warning: Safety Precautions IMPORTANT: Read these operating instructions carefully and com- pletely before trying to operate or service this tool. Improper use of this tool can cause serious injury or death from firing fastener into body or from flying debris. We expressly disclaim any liability for any injury to persons or damage to property which result from your failure to take the precautions contained in this manual. -
Page 4: Safety Precautions
Safety Precautions Always clear the work area on all sides and post appropriate warning signs on job sites. Make sure the work area is clean from loose material and debris. HANDLING THE TOOL Never place your hand over the muzzle. Accidental discharge can cause serious injury. - Page 5 Store powder actuated tool and power load strips in a locked container. Unload tool before storing. Keep power loads of different power levels in separate containers. Never carry or pass a loaded powder actuated tool. Never point a powder actuated tool at anyone. If the tool is dropped, inspect for damage and repair it before continuing to work.
- Page 6 Safety Precautions An operator taking medication should take extra precautions while handling the tool. Never drink alcoholic beverages or take medications which impair your vision, balance or judgement before using a powder actuated tool.

- Page 7 CAST IRON GLASS Never attempt to drive power fasteners into very hard or brittle materials including, but not limited to cast iron, glass, tile, stone, brick, or hardened steel. Materials of this type tend to shatter and create hazard from flying particles. Never make fastenings in spalled or cracked areas.
- Page 8 Safety Precautions 3" 482-38 Do not drive power fasteners into concrete less than three times as thick as the intended fastener penetration, within 3" of the edge, within 3" of another power fastener or within 3" of a failed power fastener. WELD 482-40 TOO THIN...
- Page 9 Should the tool fail to fire, hold the muzzle firmly against the work surface for 30 seconds. Release the trigger and remove pressure on the tool while holding the muzzle against the work surface. Again press the tool firmly against the work surface and pull the trigger. If the tool still fails to fire, hold the tool firmly against the work surface for another 30 seconds before advancing the power load strip.
- Page 10 POWER LEVEL 5 Remington power load strips are available in three power levels – green (level 3), yellow (level 4) and red (level 5). Green is lowest power level, red is highest power level. Always start with the lowest power level (green-level 3) and increase until a proper fastening is made (See page 13 “Selecting Power...
- Page 11 Shank Plastic Flute 482-60 Never use common nails or other materials as fasteners. Remington Power Fasteners are manufactured from special steel and heat treated to produce a very hard yet ductile fastener. Never pry a power load out of the strip. Prying can discharge the load causing serious injury (See Troubleshooting Guide, page 23).

Page 12: Why A Fastener Holds
Why A Power Fastener Holds WHY A POWER FASTENER HOLDS IN CONCRETE The compression bond of the concrete to the power fastener accounts for the majority of the holding power. The fastener displaces the concrete which tries to return to its original form causing a squeezing effect. Maximum holding power is achieved when the depth of penetration produces a bond on the power fastener equal to the strength of the concrete. -
Page 13: Selecting Fasteners And Power Loads
Selecting Power Fasteners and Power Loads FASTENING INTO CONCRETE The proper power fastener length can be determined by adding the thickness of the material to be fastened and the amount of fastener that will actually penetrate the con- crete. The concrete must be three times as thick as the intended fastener penetration. -
Page 14: Operation
Operation Grasp barrel assembly and slide forward rapidly until it stops. Push barrel assembly back into tool to the closed position. This sets piston into firing position. 482-70 Insert power fastener into muzzle of tool, head end first. Push the fastener until point is even with end of tool. - Page 15 Squeeze trigger to set power fastener. Be sure to keep pressure on tool during this operation. Grasp base plate and slide barrel forward rapidly until it stops. Push base plate back into liner to the closed position. This advances the power load strip and resets the piston for the next fastening.
