SET UP Unpacking Inventory Your Model H6144 left our warehouse in a carefully packed box. If you discover the nailer is damaged after you have signed for delivery, please immediately call Customer Service at (570) 546-9663 for advice. After you remove the nailer case from the box you should find the following. Save the containers and all packing materials for possible inspection by the carrier or its agent. Otherwise, filing a freight claim can be difficult. Model H6144 Inventory (Figure 1) A. B. C. D.
Compressed Air System The Model H6144 is designed to be operated at 60-100 PSI using clean, dry, regulated, compressed air. DO NOT exceed the maximum operating pressure for your model. Before using your new nailer, install a 1 ⁄4" NPT male quick connect fitting (not included) on the nailer and a matching 1 ⁄4" NPT female fitting (not included) on the air hose. Regulate the air pressure on your air compressor to the minimum PSI for your model.
Safety Yoke A safety yoke mechanism on the nose of the nailer acts as a secondary safety device. When the trigger is pressed, the nailer will not fire until the safety yoke mechanism is depressed. Before you use your nailer for the first time, check the safety yoke mechanism to ensure proper function. To do this: 1. DISCONNECT NAILER FROM THE AIR SUPPLY! 2. Make sure the magazine is empty and contains no nails. 3. Make sure the trigger and the safety yoke mechanism move up and down without sticking. 4.
OPERATIONS Loading When replacing nails in your Model H6144, follow these guidelines: Gauge: Length: Capacity: Angle: 15 11⁄4" -21⁄2" 40 34° NOTICE: A number of manufacturers' nails may fit the Model H6144. However, for best performance, we recommend you use the following Grizzly nails: G6085-G6088, G9545, G6090, G3693G3697. To load your nailer: 1. DISCONNECT NAILER FROM THE AIR SUPPLY! 2. Insert a nail stick into the T-slot at the top of the magazine as shown in Figure 3. 4.
Adjusting Depth The Model H6144 features a knurled adjustment knob (Figure 5) for setting the nail depth into the workpiece. Figure 4. Example of nail deflection. Besides damaging your workpiece, deflection can cause injury if your free hand is securing the workpiece in the location that the nail deflects. 5. Pull the trigger. If the nail drove into the wood far enough, continue with your intended operations.
Clearing Jammed Nails 4. Depress the backstop (Figure 6) inside the magazine and slide the nail stick out of the magazine. The most frequent situation with any type of nailer is a nail jam. A jammed nail must be cleared before using the nailer again. To clear a jammed nail from the discharge area on the Model H6144: 1. DISCONNECT NAILER FROM THE AIR SUPPLY! Finger Tab Backstop Figure 6. Finger tab and backstop. 5.
7. The jammed nail should now be visible; remove it from the discharge area with needle nose pliers. 8. Replace the driver guide cover and snap the quick release latch back into operating position. Replacing Pistons/ O-Rings If you use your nailer day in and day out, repair pistons are cheap insurance against wasted down time and lost profits, in the event that a piston or piston shaft becomes worn out. 4. Remove the top cap. 5.
CLEANING & LUBRICATION Cleaning Lubricating Use a good solvent to clean the nose assembly of the nailer. Always be sure that the nailer is dry before using it again. Special oil has been included with your new Grizzly nailer to help maintain its useful life. Place two to six drops of oil in the nailer air inlet (as shown in Figure 9) before every use, or after two hours of continuous use. Do not allow dust, chips, sand, etc.
