CAST IRON GLASS G 018 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. G 018 Never make fastenings in spalled or cracked areas.

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.

Always start with the lowest power level (green-level 3) and increase until a proper fastening is made (See page 13 Selecting Power Fasteners and Power Loads ). IMPORTANT: Purple (level 6) power load strips will not function in model 496 tool. G 018 Never use power loads in firearms.

G 018 482-59 Power fasteners are a permanently installed fixture. An act of demolition is required for their removal. Appropriate safety precautions must be taken. Head 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.
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 482-64 penetration produces a bond on the power fastener equal...
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.
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.

Squeeze trigger to set power fastener. Be sure to keep pressure on tool during this operation. Grasp muzzle cap and slide barrel forward rapidly until it stops. Push barrel assembly back into tool to the closed position. This advances the power load strip and resets the piston for the next fastening.
