Table Rollers
Your planer is supplied with two table rollers (Figure 14)
which turn as the stock is fed into the machine, 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 should be set at high
position. When planing smooth stock the rollers should be set
at low position.
NOTE: When raising the roller higher above the table,
the range is from zero to 0.06" (Figure 15).
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 across both rollers.
3. On one side of the table, loosen the set screws
(A, Figure 14) with a 3mm hex wrench, and turn
the eccentric shafts (B, Figure 14) to raise
or lower the rollers.
4. When proper height is achieved, tighten set screws.
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. And the table rollers must always be set parallel
to the table.

Cutterhead
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 be corrected
by following the directions in this manual.
To check the adjustments you will need feeler gauges, and a
home-made gauge block made of hardwood. This gauge block
can be made by following the dimensions shown in Figure 16.

KNIFE SETTING OR REPLACEMENT
Properly setting all three knives is essential to achieving
accurate work results. Properly set knives will last longer
andalso keep their edge (sharpness) longer by equally
A sharing the cutting workload. You may use the supplied
knife setting gauge to help you set the knives to
B
the correct height whenever re-setting or changing knives.
The cutter head on this unit is supplied with both Adjustment
springs and jack screws providing you with twooptions for
setting the knives. We suggest you try each method at least
once or twice and decide for yourself which method works
best and fastest for you.
