Grizzly T26416 Service, Replacing O-Rings Piston Assemblies, To replace piston assembly

SECTION 7: SERVICE

Always disconnect air from stapler whenever servicing! During mainte- nance, a stapler connected to air may fire accidentally, causing seri- ous personal injury!

Replacing O-Rings &

Piston Assemblies

If you use your stapler frequently, replacement piston assemblies (part Pt26416112A) and O-ring kits (part Pt26416428) are cheap insurance against wasted down time and lost profits, in the event that the piston assembly or an O-ring becomes worn out.

To replace piston assembly:

1.DISCONNECT STAPLER FROM AIR SUPPLY!

2.Remove all staples from the magazine cartridge.

3.Remove the four cap screws on the cylinder cap of the stapler, near the exhaust port.

4.Remove the cap.

5.Pull back the pusher revealing the magazine compartment.

6.Being careful not to scratch the sides of the driver guide, insert a slim and stur- dy piece of metal through the hole at the top of the magazine compartment (see Figure 12), and push the piston assembly out the back of the cylinder.

7.Place a thin film of the stapler lubri- cating oil on the O-ring of the piston assembly.

8.Insert the new piston assembly into the cylinder. Make sure that the end of the driver on the piston assembly lines up with the slit at the bottom of the cylinder. The new piston assembly should easily slide into the cylinder.

DO NOT force the piston assembly into the cylinder! If it is not easily inserted, double-check the alignment of the driver end with the slit.

9.After the piston assembly is inserted correctly, close the magazine pusher. Replace the cylinder cap assembly and tighten the 4 cap screws.

10.For more assistance, or to install a complete O-ring set, refer to the appro- priate breakdown diagram in the back of this manual for component locations.
