Piston Seal Replacement

Using a screwdriver remove the piston seal by levering it out (Fig. 12). If the seal remains in the air rifle body tube, push it downwards, and to the hole in the center, screw - in a long enough rod provided with the M5 thread. Then by gradually pulling take the rod with the seal out.

Press the new seal with the hand on to the piston front. To facilitate this operation the seal can be lubricated with a preserving grease or heated in oil to 50° C hot. In no case is the seal to be allowed to be forced on! After correct installation, there must be no gap between the seal and the piston front. Proceed carefully when introducing the piston back into the tube to avoid damage to the seal.
