4. Lower the wheel stop to reduce the depth. Raise it to

increase the coring depth and as required.

Note: To ensure that the tines penetrate fully into

the soil, weights can be added to the back of

the machine. The machine has three weight

pockets that hold the weights. When placing

weight, ensure that the load is balanced; if

using only one weight, place it in the center

pocket and if using two, place them in the

side pockets.

Note: The removable weights are heavy. Use care

when lifting them. Make sure that you can

hold them securely before lifting them. Use

caution when positioning your hands so that

you do not set them down on your hands or

ngers.

place.

6. Repeat steps 3 through 5 for the wheel stop on the

left side of the machine. Use the visual indicator

notches in the wheel stop and indicator holes in the

frame to set the wheel stops to the same height on

each side (Fig. 004).
