SERVICE INSTRUCTIONS
PDE0045 On firm ground, digging is easier if the shells are moved in and out over a short distance, while maintaining the pressure on the ground. This also makes it easier to fill the clamshell completely.
PDE0046 When working in sticky soil, do not close the clamshell completely. It will be easier to dump. Whenever possible, use trench type clamshells with ejectors. To swing the clamshell, close it a little (2 to 3 cm only) to unlock it. Rest the teeth on the ground, retract the dipper and at the same time raise the boom, set the swing in motion, raise the clamshell and lock it by opening it as soon as it is in the desired position.
PDE0047 Never let anyone guide the clamshell by hand, as their fingers could be severed.
PDE0048 When using the clamshell for earthmoving, position the clamshell so that the larger number of teeth are on the outer side of the excavation and the smaller number towards the next area to be excavated.
