SAFETY For Your Own Safety Read Instruction Manual Before Operating This Equipment The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
Safety Instructions For Power Tools 10. USE PROPER EXTENSION CORD for the tool. Make sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage rating should be listed on the motor or tool nameplate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Your extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords if they become damaged.

Compressed Air System Safety Yoke Mechanism The Model H2910 is designed to be operated at 60-100 psi. Do not exceed the maximum operating pressure for your model. A safety yoke mechanism (bump fire) 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 new nailer, install the 3 ⁄8" quick connect fitting that comes with the nailer. Install a female 3⁄8" fitting on the air hose.
OPERATION Loading The Nailer 5. To load your nailer: 1. 2. Disconnect the air supply from the nailer! Push the magazine latch in the direction shown in Figure 1. 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 driving depth. 2. Rotate the finger wheel counter-clockwise to decrease the nail driving depth. Figure 1. Releasing magazine latch. 3. 4.
To operate your nailer: 1. 2. 3. Clearing Jammed Nails Connect the air supply to the quick connect fitting. Test the loaded nailer for proper penetration. Hold the nailer perpendicular to the surface of a piece of clean scrap wood that is thick enough for the length of nails you have loaded. Depress the safety yoke mechanism on your workpiece. Before pressing the trigger, make sure your free hand is positioned out of the way of a potential path of a nail in case of deflection.
Oiling The Nailer Cleaning The Nailer Special oil has been included with your new Grizzly nailer to help maintain its useful life. Place one drop of oil in the nailer air inlet (as shown in Figure 5) before every use. Wipe off any excess oil near the nailer exhaust to avoid dust build-up. When the oil that was included with the nailer has been completely used, replace with Grizzly Model G2820 Pneumatic Tool Oil. Use a good solvent to clean the nose assembly of the nailer.
Replacing Pistons/O-Rings If you use your nailer day in and day out, Grizzly offers repair pistons as cheap insurance against wasted down time and lost profits in the event that a piston or piston shaft becomes worn out. To replace a piston: Figure 6. Removing the exhaust cap. 8. Always disconnect air from the nailer whenever servicing! During maintenance, a nailer connected to air may fire accidentally, causing serious personal injury! 1. 2. 3. 4. 5. 6. 7.
