• If blower relief valve or melt plug is activated, reduce the line pressure to 0 psi. - Shut down the P657 by disengaging the PTO, shut off the engine, and check for blockages • Disengage P.T.O. according to manufacturer’s instructions, shut off engine.
Lubrication Instructions • Use Paragon Lobe Blower Oil (part number: 409-007). Note: Front oil tank will fill slower than the rear tank. Allow oil to settle after it begins to show in the sight glass. (Fig. 6) Max Oil Fill Level...
Preventative Maintenance • A proper maintenance program will keep your P657 blower in top running condition. A newly installed P657 blower should be checked frequently during the first month of operation. Use only Paragon Blower Oil. Check oil levels and add as needed.
The correct Relief Valve has been installed properly. Melt Plug is installed on the discharge side of the blower. Sight glasses and magnetic drain plug can be seen to identify oil level in P657 oil tanks after installation. Breathers are installed in the proper location.
