are instructed to relieve the pressure.
1. At the end of each work day, stop the pump with
the displacement rod in the down position.
2. Shut off the heat and main circuit breakers and
relieve the fluid pressure.
3. Disconnect the gun from the fluid manifold, flush
the gun as instructed in manual 307546, and store
