Add Loctite 542 to the two threads at the left, and tighten the pipe plugs firmly. Add Loctite
542 to the thread at the side of the valve block, and tighten the pipe plug. Mount two roll
pins on the valve block with the groove turned upwards and a roll pin on the spool. Mount
the retaining ring and the O-ring on the spool. Mount the O-ring in the hole in the valve
block. Mount the check valve with the holes turned upwards. Screw in the check valve
completely. Add Loctite 542 to the upper part of the thread, and mount the hose fitting.
Mount the two seal rings and fittings on the valve block.
