Serious personal injury may result if safety or operational information is not understood or followed. Compressed Air System Safety Yoke Mechanism The Model H2912/H2913 is designed to be operated at 60-100 psi. Do not exceed the maximum operating pressure for your model. Before you use your new nailer/stapler, install the 3.8" quick connect fitting that comes with the nailer/stapler. Install a female 3.8" fitting on the air hose. Regulate the air pressure on your air compressor to barely over the minimum psi for your model. Many pneumatic tools benefit from an in- line filter/lubricator/regulator unit. This attachment is connected by hoses between the air compressor and the stapler. Using this unit protects your tool from damaging water build-up, allows you to adjust and maintain constant air pressure to your tool, and saves you the inconvenience of having to manually lubricate your tool every time you use it. Check the current Grizzly catalog for availability of this unit. If you plan on installing a filter/lubricator/ regulator unit in your compressed air system, always follow the connection instructions that come with the unit. Exceeding the maximum permissible operating pressure may cause the nailer/stapler to explode, blowing metal fragments in all directions. To protect yourself from serious personal injury, DO NOT allow your air compressor to exceed the recommended pressure when connected to the nailer/ stapler! A safety yoke mechanism (bump fire) on the nose of the nailer/stapler acts as a secondary safety device. When the trigger is pressed, the nailer/stapler will not fire until the safety yoke mechanism is depressed. Before you use your nailer/stapler for the first time, check the safety yoke mechanism to ensure proper function. To do this: 1. Make sure the nailer/stapler is disconnected from the air supply! 2. Make sure the magazine is empty and contains no nails or staples. 3. Make sure the trigger and the safety yoke mechanism move up and down without sticking. 4. Connect the nailer/stapler to the air supply. 5. Without pressing the trigger, depress the safety yoke mechanism against a scrap piece of wood that is clean and free of any knots, staples, or other foreign objects. If the nailer/stapler does not fire, then the safety yoke mechanism is working correctly. If the nailer/stapler does fire when you do this, immediately disconnect the nailer/stapler from the air supply and call our customer service for help. Similarly if the nailer/stapler fires when the trigger is pulled, without the safety yoke mechanism being depressed, then the nailer/stapler is not working properly. If either of these two conditions develop after you have used your nailer/stapler for a period of time, check the lubrication of these mechanisms. The safety yoke is a mechanical device that can fail. Never rely on the safety yoke mechanism as an excuse to point the tool at yourself or any bystanders. Serious injury may occur. -5- H2912/H2913 2-IN-1 NAILER/STAPLER OPERATION Loading The Nailer/Stapler To load your nailer/stapler: 1. Disconnect the air supply from the nailer/stapler! 2. Push the magazine latch in the direction shown in Figure 1. stops. 4. Point the nailer/stapler up and insert a stick of nails/staples into the magazine as shown in Figure 2. Make sure that the pointed ends of the nails/staplers point in the same direction as the Model H2912/H2913 nose and the nails/staples rest in the slot at the bottom of the magazine. Figure 2.

Rotate the finger wheel counter-clock- wise to decrease the nail/staple dri- ving depth. 3. Pull back the magazine cover until it 5. Push the magazine cover forward until the magazine latch locks in place. Depth Adjustment 1. Rotate the depth adjustment wheel (shown in Figure 3) clockwise to increase the nail/staple driving depth. Operating The Nailer/Stapler If you have not read the safety instructions in this manual, do not operate the nailer/stapler. Before you operate your nailer/stapler, place one drop of the included oil into the quick connect fitting where the nailer/stapler connects to the air supply. Fire the EMPTY nailer/stapler 3-4 times before beginning, so oil does not come out onto the project during regular operation. -6 To operate your nailer/stapler: 1. Connect the air supply to the quick connect fitting. 2. Test the loaded nailer/stapler for proper penetration. Hold the nailer/stapler perpendicular to the surface of a piece of clean scrap wood that is thick enough for the length of staples/nails you have loaded. Depress the safety yoke mechanism on your workpiece. 3. Before pressing the trigger, make sure your free hand is positioned out of the way of a potential path of a staple/ nail in case of deflection. (Deflection is caused when the staple/ nail changes its path, resulting in the staple/nail puncturing the surface of the workpi...
