Using the Half Block Insert
Two critical points must be observed when using the half block insert: 1) Be sure to completely fill the mould box, tamping the soil down as you add it, and 2) during the compression cycle, keep an eye on the Maximum Compression Indicator. DO NOT allow the indicator to rise above the line marked on the body of the mould box. Doing so can damage the half block insert and the machine itself. When the indicator meets the line, RELEASE THE AIR CONTROL VALVE.


When using a half block insert, STOP compressing when the indicator reaches the line.

Should the maximum compression line become damaged or hard to see, you can remark the correct location using the steps below.

  1. Open the lid and place the half block insert inside the machine.

  2. Place a level or a perfectly straight piece of wood on top of the mould box (see photo below).

  3. Depress the air control valve and SLOWLY raise the piston until the center divider plate just touches the level.

  4. Using a permanent marker, draw a short line on the mould box even with the tip of the red indicator as shown in the photo above.
