Page 14: Why A Fastener Holds
Safety Precautions NEVER use fasteners longer than 68mm (2 11/16"). NEVER use com- mon nails. Remington Power Fas- teners are manufactured from spe- cial steel and heat treated to pro- duce a very hard, yet ductile fas- tener. Remington tools drive flat- headed fasteners. - Page 15 Safety Precautions Head Shank G 018 Plastic Flat-headed Dome-headed Flute G 018 LOAD UNLOAD Overdriven Fasteners An overdriven fastener results when too strong of a power load is used causing the piston to extend past the muzzle. Move to the next lightest power load. Repeated overdrive will damage your tool.

Be sure to keep holding the muzzle downward and away from you. - Page 17 Operation Chamber Muzzle Firing Grip Barrel LOADING Firing Line Up Grooves Spring Must Be Compressed FIRING EJECTING Continued...
- Page 18 Operation After the fastening is made, remove the tool from the work surface. Grab the barrel and pull forward rapidly. This ejects the spent load and sets the piston in the firing position. NOTE: THE TOOL CANNOT BE FIRED IN THE OVERHEAD POSI- TION.
