Never attempt pressure bar
adjustment while planer is connected to
power.
Feed restriction can also occur due to pitch
buildup on the table. Be sure the table surface is
clean. Occasionally dusting the surface with talc
will aid in smoother feeding and help prevent
pitch buildup.
Halted Feeding
If the infeed roller takes the stock, the
chipbreakers lift, and just as you hear the knives
contact the material, it stops feeding, then the
pressure bar is too low. Reset the pressure bar
(see page 13).
Maintenance
Periodic inspections are required to ensure that
the machine is in proper adjustment, that all
screws are tight, that belts are in good condition,
that dust has not accumulated in the electrical
enclosures, and that there are no loose or worn
electrical connections.
Buildup of sawdust and other debris can cause
your machine to plane inaccurately. Periodic
cleaning is not only recommended but
mandatory for accurate planing.
Close-fitting parts, such as the table locking
rods, the cutterhead slot and gibs, should be
cleaned with a cloth or brush and non-
flammable solvent and freed from clinging
foreign matter.
Use caution and proceed
slowly when working with or around the
cutterhead knives.
Remove resin and other accumulations from
feed rolls and table with a non-flammable
solvent.
Periodically check all the chains and belts for
proper tension and adjust accordingly if
required.
TIP: If a foreign object nicks the knives on the
straight cutterhead (Model 201), instead of
throwing them away or trying to grind out the
deep nick, simply stagger the knives in the
head, moving one knife no more than 1/4” to the
right and another knife no more than 1/4” to the
left. The nick will not be noticeable.
Lubrication
The gear box oil should be changed at least
once a year. Remove the drain plug (A, Figure
25) to drain the oil into an appropriate container.
Replace the drain plug and fill the gear box with
60 to 90 weight gear oil through the fill hole (B,
Figure 25). Capacity is 0.494 gallon (1.87L). The
sight glass (C, Figure 25) should be checked
periodically and oil topped off as necessary.

The recommended lubrication for roller chains
used in medium to slow speed operation is to
simply wipe the chain clean. When there is an
appreciable buildup of dust, dirt or wood
shavings, use an oil cloth but never pour the oil
directly on the chain. Over-oiling defeats the
purpose of the lubrication, since it tends to invite
the collection of dust, shavings, etc. and works
into members of the chain. This hastens wear
and leads to premature replacement.
The bearings on the cutterhead and feed rollers
are factory lubricated and sealed. They require
no further attention.
