As a general rule, penetration should be approximately 1" to 1 1/4" into the base concrete. Maximum holding power is achieved when the depth of penetration produces a bond on the power fastener equal to the strength of the concrete. The fastener displaces the concrete which tries to return to its original form causing a squeezing effect. 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. NEVER pry a powder load out of the chamber. Remington® Power Fasteners are manufactured from special steel and heat treated to produce a very hard yet ductile fastener. 482-59 NEVER use common nails or other materials as fasteners. Appropriate safety precautions must be taken. An act of demolition is required for their removal. Power fasteners are a permanently installed fixture. Remington® Powder Loads are available in four power levels with gray (1) being the lowest power level and yellow (4) being the highest power level.

If the tool still fails to fire, hold the tool firmly against the work surface for another 30 seconds before unloading and carefully discarding the misfired powder load into water or oil. Again press the tool firmly against the work surface and pull the trigger. Release the trigger and remove pressure on the tool while holding the muzzle against the work surface. Should the tool fail to fire, hold the muzzle firmly against the work surface for 30 seconds. DO NOT drive power fasteners into steel base material less then 3/16" thick, within 2" of a weld, within 1/2" of the edge, or within 1" of another power fastener. 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. NEVER drive power fasteners into thin or easily penetrated material unless it is backed by concrete or steel.
NEVER make fastenings in spalled or cracked areas. Materials of this type tend to shatter and create hazard from flying particles. 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.

NEVER drink alcoholic beverages or take medications which impair your vision, balance or judgement before using a powder actuated tool. An operator taking medication should take extra precautions while handling the tool.
If the tool is dropped, inspect for damage and repair it before continuing to work. NEVER point a powder actuated tool at anyone. NEVER carry or pass a loaded powder actuated tool. Keep powder loads of different power levels in separate containers. ALWAYS store UNLOADED powder actuated tool and powder loads in a locked container.

Accidental discharge can cause serious injury.
ALWAYS make sure the work area is clean from loose material and debris. 489-09 ALWAYS clear the work area on all sides and post appropriate warning signs on job sites.
