ADJUSTING
TABLE LEVEL
Refer to Figures 19 and 20, pages 14 and 16.
The planer will produce uneven depth of cut (tapered
cut) if the rollercase (Fig. 20, Key No. 34) is not parallel
with the base (Fig. 19, Key No. 35). To restore paral-
lelism of the rollercase with the base:
Using a test piece, measure the height of the taper.
• Turn planer off and disconnect form power source.
Lay planer carefully on it's side so that bottom side
of the base is exposed.
Loosen socket head bolt holding idler bracket (Fig.
19, Key Nos. 46 and 44). Loosen chain.
Rotate lead screws (Figure 19, Key Nos. 30 and 32)
as needed. Each turn of screw by one sprocket tooth
will move that corner of rollercase by about 0.006".
