     DANGER 
Do not attempt to operate this 
tool until you have read and 
understood all safety precautions 
and manual instructions. 
Failure to follow all safety precautions and instructions
may result in a permanent loss of vision, serious 
personal or even fatal injury, property damage 
and/or tool damage.
  The GypFast (G2) Tool is an 
  internal combustion device. It 
  produces hot exhaust gases that 
  may ignite flammable 
materials. 
This tool must not be used in a combustible  
environment or in the presence of combustible 
materials, such as flammable chemicals,  
adhesives, gasoline, or solvents. 
  Do not expose the tool to  
  temperatures in excess of   
  120°F (49°C). Fuel and/or the 
  battery may burst, releasing 
  flammable gas. 
  This tool must be operated only 
  in a well-ventilated environment, 
  because the tool exhausts carbon  
  monoxide similar to a gas chain 
  saw or lawnmower. Exposure  
to carbon monoxide may cause dizziness, nausea, 
or unconsciousness. 
  ALWAYS keep the GypFast (G2)  
  Tool, fuel cell, battery and  
  battery charger out of the reach  
  of children.  
1. READ THIS MANUAL FROM COVER TO COVER.
Always turn to this manual for information about 
the safe operation and servicing of the GypFast (G2) 
tool. If any portion seems unclear, or you have 
any questions, contact your Ramset Distributor 
Representative immediately. 
2. WEAR EYE AND HEARING PROTECTION. 
Always wear hearing and eye 
protection devices when you are 
operating the GypFast (G2) tool or 
working in the vicinity of this tool. 
Also, your eye protection must 
meet the requirement of ANSI 
Standard Z87, and should have side shields for 
increased protection. 
3. NEVER ASSUME THE TOOL IS EMPTY. Every 
time you pick up the GypFast (G2) tool, check the 
Magazine for fasteners. Never point the tool at 
anyone or yourself, even if you are absolutely sure 
there are no fasteners in the tool. The fastener you 
did not see is the fastener that can injure you  
or someone else. 
4. NEVER ENGAGE IN “HORSEPLAY” WITH THE
TOOL. The GypFast (G2) tool is not a toy. . . it  
is a power fastening tool. It is designed to drive  
a fastener through gypsum board or plywood  
sheets into steel studs. To accomplish this task, 
it generates a tremendous amount of energy. 
Fooling around, even when you are absolutely 
sure there are no fasteners in the tool, is asking  
for an accident.
