Operation Instructions 1. Place a representative sample of concrete in 3 equal layers, consolidating each layer by rodding and tapping the bowl, vibration may be substituted. 2. Using a sawing motion, strike off the excess concrete across the top flange with the screeding tool. Wipe the flanges clean. 3. Clamp the cover on with the petcocks open. 4. Using the plastic wash bottle (supplied), inject water through one petcock untilnnmm all the air is expelled through the opposite petcock. 5.
. Pump up air pressure to a little beyond the pre-determined initial pressure line. 5. Wait a few seconds for the compressed air to cool to ambient temperature, then stabilize the gauge hand at the proper initial pressure point by pumping or bleeding off as needed. 6. Close both petcocks and immediately crack open the “hands-free” valve, exhausting air into the base. 7. Wait a few seconds until the hand is stabilized.
3. Maintenance of the “hands-free” valve: Unscrew the valve stem from the valve body using the top brass hex nut. Using a coarse piece of emery cloth or sandpaper, remove the debris and wear lines on the brass valve taper with 2 or 3 quick sandings. One, or two quick polishes with 500 emery cloth finishes the cleaning. Coat the valve taper with white lithium or plumber's grease.
