2. Check belt tension. Proper
tension is obtained when
there is approximately
1/4" deflection of the
center span of the pulleys
using light finger pressure
(Fig. 10).

3. If adjustment of belt tension is necessary, loosen one
pair of hex nuts (E & F,
Fig. 11) and turn the other
pair to raise or lower
the motor plate.

Table Rollers
Overview
Your planer is supplied with two table rollers (A, Fig. 12)
which turn as the stock is fed into the planer, thus reducing
friction. It is not possible to give exact dimensions on the
proper height setting of the table rollers because each type
of wood behaves differently.
As a general rule, however, when
planing rough stock, the table rollers

Note: When raising the roller higher above the table, the
available range is from .003" to .006" See Fig. 13.
1/4" deflection
The table rollers are factory set for average planing and are
parallel to the table surface. If you desire to adjust the table
rollers higher or lower, proceed as follows:
1. Disconnect machine from power source.
2. Lay a straight edge (B, Fig. 14) across both rollers.
3. On one side of the table, loosen the screws (C, Fig. 14)
with a hex wrench, and turn the eccentric shafts
(D, Fig. 14) to raise or lower the rollers.
4. When the proper height is achieved, tighten screws
(C, Fig. 14).
5. Adjust the rollers from the opposite side of the table in
the same manner.
Important: Be sure that the height of front and rear rollers are
the same. The table rollers must always be set parallel to the
table.

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
