Replacing Pistons/O-Rings

If you use your nailer/stapler day in and day out, Grizzly offers repair pistons as cheap insurance against wasted down time and lost profits in the event that a pis- ton or piston shaft becomes worn out. To replace a piston:

Always disconnect air from the nail- er/stapler whenever servicing! During maintenance, a nailer/stapler connected to air may fire accidental- ly, causing serious personal injury!

1.Disconnect the nailer/stapler from the air supply!

2.Remove all staples/nails from the magazine cartridge.

3.Remove the 4 cap screws from the exhaust cap.

4.Remove the exhaust cap as shown in Figure 6.

5.The top of the piston should now be visible inside the cylinder, which is housed in the head.

6.Open the magazine.

7.Watch the discharge area and push the top of the piston with your finger. You will see the piston shaft slide down the discharge area.

Figure 6. Removing the exhaust cap.

8.With a long flathead screwdriver or similarly shaped tool, push the piston shaft back inside the nailer/stapler until you can grip the piston head and remove it from the cylinder. (Be care- ful not to scratch the discharge area when pushing the piston shaft with the screwdriver.)

9.Place a new O-ring on the new piston and apply a thin film of lubricating oil on the O-ring.

10.Insert the new piston in the cylinder. Make sure that the grooves on the piston shaft line up with those on the guide. The new piston should easily slide into the cylinder. Do not force the piston into the cylinder! If the piston is not easily inserted, double- check the alignment of the piston shaft with the grooves on the guide.

11.After the piston is inserted correctly, close the magazine. Replace the rear cap assembly and tighten the 4 cap screws.

12.For more assistance, or to install a complete O-ring set, refer to the appropriate breakdown diagram in the back of this manual.

H2912, H2913 specifications

Grizzly H2913 and H2912 are two advanced models in the Grizzly lineup, designed for woodworking enthusiasts and professionals who demand precision and versatility in their tools. These models are particularly noted for their robust construction, ensuring durability and long-lasting performance for a wide range of applications.

The Grizzly H2913 is a powerful 12-inch planer that stands out for its impressive planing capacity and efficient motor. One of its main features is the combination of a helical cutter head, which enhances cutting performance by providing a smoother finish with minimal tear-out. This innovative design utilizes multiple carbide-tipped inserts that allow for easy replacement, saving time and ensuring consistent results with every use. The planer offers variable feed rates, enabling users to adjust the pace depending on the material being worked on, further enhancing its adaptability.

On the other hand, the Grizzly H2912 is a 15-inch thickness planer, ideal for larger workpieces and more demanding tasks. This model also features a helical cutter head, providing the same benefits as the H2913, including a higher-quality finish and reduced noise levels during operation. The H2912 is equipped with a robust cast iron table, which contributes to its stability and reduces vibration while planing. This reliable construction results in a flatter surface, crucial for achieving precise thickness.

Both models are designed with user convenience in mind. They come with easy-to-read digital displays that provide precise thickness adjustments, making it simple for users to set their desired dimensions. Additionally, the integrated dust collection ports help maintain a clean workspace by efficiently directing debris away from the machine.

Moreover, Grizzly H2913 and H2912 feature durable built-in handles for easy transport and adjustment, allowing users to move them effortlessly between different work areas. The overall design reflects a commitment to quality and user friendliness, ensuring these planers can meet the demands of both novice woodworkers and seasoned professionals alike.

In summary, the Grizzly H2913 and H2912 represent a blend of cutting-edge technology and traditional craftsmanship, making them essential additions to any workshop focused on premium woodworking. Whether you prioritize planing quality, operational efficiency, or user-friendly features, these models deliver outstanding performance tailored to various woodworking projects.
