◊ ADjUsTInG DrIVe BeLT TensIon
Drive belt tension should be checked regularly.
1. Disconnect planer from power source.
2. Remove the belt cover knobs and the belt cover.
3. Apply moderate pressure on the belt halfway between
the two pulleys. A properly tensioned belt should deflect
by about ¼”.

◊ FEED ROLLER TENSION
The feed rollers are under spring tension and the
tension must be sufficient to feed stock uniformly
through the planer without slipping, but should not be
so tight that it causes damage to the board. The tension
should be equal at both ends of each roller. To adjust
the tension, turn the tension screw at both ends of the
roller.
Do not put excessive tension. If the tension is too heavy,
it will result in important snipe at the beginning or at the
end of the board. As a basis, four threads should show
above the casting for the tension screws of the infeed
roller (A) , and one thread should show above the
casting for the tension screws of the outfeed roller (B) .
Further tension adjustment may be necessary.

◊ TABLE PARALLEL TO CUTTER HEAD
The working table is set parallel to the cutter head at
the factory and no further adjustment should be
necessary.
If the machine is planning taper, first check if knives are
properly set in the cutter head. If distance from the table
to the edge of the head casting is not the same at both
ends and needs readjusting, contact service
department. Most customers do not want to tackle such
a job themselves.
Belt and pulleys may be hot after operations.
Allow components to cool before servicing.

If belt needs adjustment:
4. Loosen the three bolts (C) Fig. 14, and pry up on motor
plate until correct belt tension is obtained. Correct
tension is where there is approximately 1/4” deflection
in the center span of the belts using light finger
pressure. Then tighten the three bolts (C) and replace
belt pulley cover.
