9.8.1. Setting the zero position for planing depth adjustment
If shallow planing is required, which therefore entails greater accuracy, the zero position on the measuring rod
can be set according to the level of the ground where the planing is required.
The following operations must be carried out:
1- Following the procedure outlined in paragraph 9.8, set the planing depth at the minimum (tighten both
depth adjustment screws fully);
2- Make sure the side plates are resting on the ground and that the ground is flat and compact;
3- Change the depth setting (see para. 9.8) using both screws until the drum is skimming the ground.
Turn the drum by hand (opening the inspection cover, para. 10.1) to check that all the teeth skim the
ground and are also perfectly parallel to it;
4- Loosen the nuts (fig. 4) on both of the depth adjustment screws;
5- Adjust both the adjustment screw rods so they are at “0” on the measuring scale;
6- Tighten the adjustment screw nuts (fig. 4) and set the planing depth required, following the
procedures outlined in paragraph 9.8.
