SAFETY RULES
1. This machine has been designed with as many safety features as humanly possible, however, always remem·
ber
that a planer is only as safe as its operator.
2. BEFORE starting planer be sure to check the following:
(a) Table must be completely free of all foreign matter.
(b) Cutterhead knives MUST be inspected before each operation. Check for tightness in cutterhead
and make certain knives are not fractured in any place. Flying knives are DANGEROUS.
(c) Knives
for sharpness!!
3. Check material thickness and depth of cut desired. Never overload planer, or try to cut beyond its capac-
ity.
4. As material is fed into machine, stand to side of board (never directly behind), nearest switch. "Kick-
back," caused by
improper gripping of lumber by infeed roll and chipbreaker, can cause serious injury.
5. Never stand directly behind or walk behind machine when it is running. Direction of cutterhead rotation
usually throws chips or any foreign material from rear of machine.
6. In case it is necessary to stop material as it is feeding through machine, disengage feed clutch and turn
machine off. Wait until cutterhead has completely stopped before lowering table to remove material. At·
tempted removal while cutter head is turning may cause "kickback."
7. Nev er horse around a running planer. "Play" should absolutely be forbidden as 9 out of 10 accidents are
the results of carelessness and playing with machine as though it were a toy.
8. Always stop machine for adjustment or when leaving immediate area . Disconnect power source when
working on or around
any moving parts.
9. Never feed two boards through a planer with solid infeed rolls, at once (side by side or stacked). Kick-
back can result
and board fly from machine with velocity of bullet.
10. Use only genuine Powermatic (or factory authorized) replacement parts and knives-otherwise all war·
ranty and guarantees are null & void.
11. Keep all guards in place-and use them.
12. Do not wear long or loose sleeves or neckties when operating planer.
13. Extra care should be taken when running short pieces, butt with another piece of material of equal thick·
ness and Rtand ASIDE.
t Base of machine Rho uld be grounded to water pipe or central grounding system.

OPERATING INSTRUCTIONS
OPERATING ADJUSTMENTS
The planer bed mounts in the main frame panels and is held rigid
by the shims and adjusting screws (2) located in front of the
machine. The bed is raised and lowered by the g ears and thrust
screws through the handwheel (1). Keep shims adjusted to hold I'
planer bed rigid in ways but not too tight to re s trict freedom of
raising and lowering with handwhe e l. The planer bed must also
be level
with cutterhead. Check this by lowering bed to allow
placing a small
jackscrew type guage or block hptween one
extreme end of cutterhead. Slide gauge to opposite end of
cutterhead to determine if same measurement exists. If bed is
out of level adjust in following manner. Loosen set screws in
screw nut (3) on high side of bed and turn nut to left until bed
is level and
tighten set s crew in nut.
The adjusting screws (4) for the planer bed idler rollers are
located directly under the bearings. Adjust .006" to .010"
above bed level
for planing smooth or dry mat erial, and .015"
to .025"
for rough sawed or green mat erial. Keep rollers adjusted
to same height at both ends. When rollers are set too high a
snipe
or bitE' out will appear on both ends of planed material. If
set too low. feedin l?, ' will be restricted thr ough material friction
on
planer be,t
There are two power driv en feed rollers. One corrugated infeed
(7) and one smooth outfeed.
The feed rollers are held with a
spring loaded plung er slide with tension to regulate the pressure.
Pressure on feerl rollers is regulated with s pring cap screw (12).
To increase
pressure , turn screw to right, to decrease, turn to
left.
The feed rollers are held up with stud bolts (3) and are
raised or lowered by loosening lock nut on bolt (13) and turning
to the right to raise, or to the left to lower rollers. Feed rollers
should be
set .030" below the arc of the knife cut and the rollers
should be parallel
with planer bed. To set feed rolls, lower
planer bed about 3" below arc of cutterhead. Place gauge di-
rectly under cutterhead and turn head until one knife is down.
Raise bed until gauge is .001" below knife. Feed roller setting
may be checked by feeding a short board through the machine,
8" or 10" wide and planing off a light cut. After the Qoard has
been fed through the machine, feed it through the machine un-
til both feed rollers touch
the board. (Stop with Clutch.)
There should be 1/32" clearance between the spring cap screw
(12) and stud screw nut (13). If the rollers are not properly
adjusted, they may be adjusted at this time.
The chipureaker may ue raised from the cutterhead with handle
(18) exposing
adjustments (15) that adjLst the height of the
chipbreaker. Chipbreaker should be s et .030" below arc of cut-
terhead knife. Chipbreaker should re st on material while it is
being fed
through the machine. When the material is fed
through, chipbreaker should raise approximately 1/32".

OPERATING INSTRUCTIONS
The holddown
bar is adjusted with adjusting nuts (14) and
should be adjusted .003" below arc of cutter head knife. To ad-
just holddown bar, loosen lock nut and turn adjusting screw
(14) to
the right to raise and to the left to lower.
To
adjust feed belts, loosen nuts (20) on the inside of planer
frame and slide studs in slots until belts have proper tension.
If machine does not feed properly remove guard and check for
belt slippage.
The infeed
and outfeed rollers have grea se fittings (8) and (9).
Feed drive sheaves are lubricated at (16) and (17). These
fittings
require greasing every ten (10) hours of operation with
No.1 grease, or a light weight type.
Planer bed ways, bed raising screws, bed idle roller bearings
should be greased every ten
(10) hours of operation with SAE
No. 10 oil or equivalent.
To set
the indicator on the material thickness scale (6) to indi-
cate properly after changing knives, loosen the screw in the
planer bed which holds the brass pointer and set to the thickness
the material measures when planed or fed through the machine.
The hole which mounts the
brass pointer is slotted and will per-
mit proper adjustment.
The cutter head is equipped with three knives held in position
with the lock shims and set screws (10). Knives must be ad-
justed to set evenly and level in the cutterhead. Before remov-
ing knives from cutterhead,
the knife gauge should be adjusted
to the height of the knives. so the height of the knives will not
be changed relative to the
other parts of the head when the
knives
are replaced. The feed rollers, chipbreaker and pressure
bar are adjusted to the arc of the knife cut. If the height of
the knives are raised or lowered, the feed rollers, chipbreaker
and pressure bar should be adjusted accordingly. Knives should
not
protrude more than .030" beyond radius of cutterhead.
When replacing knives
after sharpening, place the "jack screw"
studs in place making sure the "step" will act as a seat for the
knife. Drop knife and shim into cutterhead slot so that the
beveled edge of knife is just below the surface of the head.
Tighten the two outside knife shim screws just enough to hold
the knives snugly in the head., With knife settin~ gauge in
place over one
extreme end of the head, turn the allen screw in
"jack screw" plugs, raising knife until knife touches stop on
knife setting gauge. Repeat operation on other end of the cut-
terhead.
Next, tighten the center knife locking shim bolt. Set
the other knives in the cutterhead before tightening remainder of
the shim bolts.
After th~ knives have been set, final locking
of knives should be done by rotating cutter head and locking all
shims uniformly.
CAUTION-If one knife is locked tightly
before
the others, it may spring the cutterhead and cause vi-
bration or uneven knife height.
IMPORTANT: Knives should be kept sharp. The knives do all
of
the work and they will not do satisfactory work if they are
DULL. The sets of knives are matched and balanced at the
factory. When the knives are sharpened, care should be taken
that they are kept in balance.
