Adjusting Depth of Cut

The cutting depth scale (A, Fig. 16) is a combination inch/metric scale with a cutting range from 0 to 8” (204mm). The distance of upward or downward movement is controlled by the handwheel (B, Fig. 16). One revolution of the handwheel is .059” (1.5mm). Before moving the table up or down, loosen the lock nuts (C, Fig. 16). After obtaining the proper table position, tighten the lock nuts (C, Fig. 16).

Always tighten the lock nuts before operating the planer.

Cutterhead Adjustment

Overview

Although your planer was carefully adjusted at the factory, it should be checked before being put into operation. Any inaccuracies due to rough handling in transit can easily be corrected by following these directions.

To check the adjustments you will need a straight edge, feeler gauge, and a home made gauge block made of hardwood. This gauge block can be made by following the dimensions shown in Figure 17.

Knife Adjustment

When checking or adjusting the cutterhead knives, proceed as follows:

1.Disconnect machine from power source.

2.Remove the six screws (A, Fig. 18) and remove upper cover (B, Fig. 18).

3.To check and adjust knives, use the provided knife gauge (Fig. 19 & 20) and check all four knives. Knives should just contact the bottom of the center protrusion (D, Fig. 19) of the knife gauge.

4.If an adjustment to one or more of the knives is necessary, slightly loosen the knife gib (E, Fig. 19) by turning the six locking screws (F, Fig. 19) into the gib. Turn the screws just enough to relieve stress in the cutterhead without disturbing the setting of the knives. Do this for all four knives at the same time.
