DANGER SAFETY INTRODUCTION DANGER THIS TOOL IS TO BE USED ONLY BY PROPERLY TRAINED AND LICENSED OPERATORS. YOU MUST SUCCESSFULLY COMPLETE ITW RAMSET/RED HEAD’S TRAINING PROGRAM FOR THE TOOL AND OBTAIN A CERTIFIED OPERATOR’S LICENSE BEFORE HANDLING, LOADING OR OPERATING THIS TOOL. ATTEMPTING TO HANDLE OR OPERATE THIS TOOL WITHOUT PROPER TRAINING AND LICENSING CAN RESULT IN SERIOUS INJURY TO THE OPERATOR OR BYSTANDERS. Operator’s and bystanders must wear eye and hearing protection.
SAFETY INSTRUCTIONS DANGER Preparation Acceptable Base Materials Powder actuated fastening is suitable for use in the following base materials only: • Poured Concrete • Structural Steel • Masonry Joints ( see page 8) Never attempt to fasten into any other type of material. Fastening into other materials can cause blindness or other serious injury.
DANGER SAFETY INSTRUCTIONS Loads & Load Selection Safety 1. Always make a test fastening after being sure that the base material is suitable for powder actuated fastening. Failure to determine the correct power level to be used may result in the use of excessive power, allowing the fastener to pass completely through the work material, causing serious or fatal injuries to others who may be in the path of the fastener. 2.
DANGER SAFETY INSTRUCTIONS Tool Handling Safety 1. Always be sure tool is operating properly before attempting to use it. Follow the “Daily Function Check” shown to the right and described on page 9. 2. Always load tool using a load strip selected directly from a box indicating the power load type and number. Never attempt to use loose strip loads that could be mis-identified. 3. Never carry loose strip loads in pockets with pins or other hard objects. 4.
DANGER FAILURE TO FOLLOW INSTRUCTIONS CAN CAUSE INJURY TO THE TOOL OPERATOR OR TO BYSTANDERS. SAFETY INSTRUCTIONS Fastener Driving Safety 1. Only use the tool for fastening into a suitable base material. 2. Never fire the tool without a fastener. Firing a tool without a fastener will cause the piston to strike the work surface, and may cause serious injury to you and others in the work area. 3. Always use the spall guard whenever possible to minimize flying particles or debris. 4.
FASTENERS / LOADS Your Ramset Viper tool uses only the Ramset fasteners and loads shown below or listed for the tool in the Product Catalog. DANGER Never use any other types of fasteners or strip loads in the Viper tool. Use of other types of fasteners or loads may cause unintentional load discharge, damage the tool, cause poor fastening performance, or create a risk of seroius injury to the operator or bystanders.

FASTENING APPLICATIONS FASTENING APPLICATIONS Your Ramset tool can be used for a wide range of fastening needs in a variety of base materials. Reading and following these important fastening guidelines will help you get the best results from your tool, fasteners, and powder loads, as well as help you perform these fastening operations safely and effectively.
TOOL OPERATING INSTRUCTIONS TOOL OPERATION Daily Function Test Always check the tool first to make sure that it does not contain a load strip or fastener. Test the tool overhead several times by completely depressing it on a hard surface. You should hear an audible click as the firing pin releases. Let up on the tool and check to be sure that the barrel assembly has opened to the starting position. Next, place the tool, pointing downward, on a hard surface and firmly, completely depress the tool.
TOOL OPERATING INSTRUCTIONS 4. Lower the tool, keeping it pointed in a safe direction, and insert the next fastener or fastener assembly. Note: While the Viper tool is being closed and fired, the advance lever cam has caused the load advance lever to be indexed downward to pick up the next load. When the tool is lowered and opens up, the next unfired load is indexed upward to the firing position. At the same time, as the tool is lowered, the piston is automatically reset for the next fastening.
TROUBLESHOOTING REFER TO PARTS SCHEMATIC FOR PROPER ASSEMBLY OF PARTS - Overdriving of fasteners - Excessive power - Change to next lower power level load strip color and number. - Soft base material - Check base material (see page 3) - Failure to depress completely - See “ Tool does not completely depress” - Excessive dirt buildup on breech face not allowing proper penetration of firing pin - After following misfire procedure, check firing pin indentation on load.
