screws.
NOTICE
More adjustments may be necessary to the
roller spring tension after the machine has
been test run and is in safe working
condition. See the
Operations section for
more details.
Figure 26. Chain tensioner.
After setting the feed rollers, the chipbreaker
and the pressure bar, the chain tensioner
(shown in Figure 26) must be reset for the
planer to operate properly. Incorrect chain
tension may cause the feed rollers to jam or
even cause the chain to break.
To adjust the chain tensioner:
1. Remove the chain drive cover and the
backing plate.
2. Place the block of wood described on page
14 under the right side of only the outfeed
roller. Raise the table up so the block barely
touches the outfeed roller.
3. Look at the current table height on the
scale. Raise the table up 1mm, using the
scale as a gauge. This will move the outfeed
roller up approximately .040".
4. Loosen tensioner bracket screw, rotate the
chain tensioner until the chain is tight, then
secure the tensioner bracket screw to keep
the tensioner in place.
5. Replace the backing plate and the chain
drive cover.
The power should not be
connected to the planer
at this time! If it is,
serious injury may occur.
Roller spring tension keeps the roller pressure
uniform as the workpiece moves through the
planer. To adjust the roller spring tension:
1. Figure 27 shows the four spring adjustment
screws. Adjust screws A, B & C so they
protrude 1 ⁄
8
" above the head casting.
2. Adjust screw D so it protrudes 5 ⁄
16
" above
the head casting. This extra height will
compensate for the pressure of the chain
during operation.
