I. GENERAL SET-UP AND ALIGNMENT
1. RECEIYING
Uncrate and check for shipping damage. Clean all coated
and greased surfaces. Read instructions thoroughly.
Lo-
cate all lubrication points; adjustment; methods of drive .
2. MOUNTING
Mount machine securely to solid foundation. Concrete
base mounting preferred. Locate
in clean, dry and well
vent.ilated building if p()ssible.
Motor and electrical con-
nections should be protected when not
in operation or if
exposed to weather elements.
3. EXHAUST SYSTEM
Recommended as a must if efficient production operation
is required. Not a necessity where limited amount of
operation being performed and machine can be kept
clean
of shavings.
4. INSPECTION
The above machine requires the minimum amount of
attention in service. Periodic or regular inspections are
recommended to insure machine is in proper adjustment,
positive electrical connections; worn
or loose "Y" belts and
bearings heating or loose.
5. BEFORE OPERATING
Check motor nameplate date or wiring diagram of motor
and switch
for proper voltage connection before wiring
into line. Run motor without load to check the connections
and direction
of rotation. Always refer to motor name-
plate for rotation connections.
II. LUBRICATION
1. The cutterhead and variable speed pulley are mounted in
sealed bearings
and do not require any lubrication.
2. GREASE LUBRICATION
The clutch, table and feed rollers are equipped with pres-
sure gun fittings and must be lubricated
regularly every
twenty-five hours
of operation with a good grade High
Speed Boll Bearing grease. Also, the feed
drive gears
should be surfaced greased with the same grease.
3. OIL LUBRICATION
The surface fittings, bed ways, handwheel drive shaft
gears and thrust screws should be lubricated
regularly
every ten hours of operation with oil equivalent to SAE 10.
A light film
of oil on the table when not in use will prevent
rusting.
III. OPERATING ADJUSTMENTS
PLANER BED:
The planer bed mounts in the main frame panels and is
raised and lowered on acme screws mounted in thrust
bearings.
The screws are operated through gears by a
large hondwheel (l ) on the front
of the Planer.
The planer bed is held rigid between frames by shims on
each side
of the bed and is adjusted with two jack screws
(
12 ) that can be tightened against the shims. These shims
should be adjusted
tight enough to prevent rocking or
moving when material is fed through the Planer but not
tight enough to prevent raising
or lowering of the table .
If planer bed rocks when the machine
is in operation, dips
will appear in the material being planed . The planer bed
POWERMATIC/HOUDAILLE
OPERATING INSTRUCTIONS
must be level with the cutterhead. Check this by lowering
the bed
to permit placing a small jack-screw type gauge
( or small square block) between the bed and the cutter-
head
at the extreme right side of the bed. Raise bed with
handwheel (1) until the screw
gauge or block just touches
the cutterhead. Move the block
to the left side of the
table and check under the cutterhead. If the bed is not .
level with the cutterhead, the bed can be raised or
lowered
by loosening the set screw· in bed nut (13) and
turning
to the right or left to raise or lower the bed to the
proper height-lock the bed nut with the set screw.
PLANER BED IDLER ROLLERS:
Adjusting screws (14) for planer bed idler rollers are lo-
cated
directly under the bearings. Adjust from .000 to
.
010" above bed level for planing smooth or dry material,
.010" to .015" for medium rough and . 025" to .035" for
rough sawed or green material. Keep rollers adjusted to
same height
at each end. When rollers are set too high,
a snipe
or bite will appear at the ends of planed material.
If set too
low feeding will be restricted due to friction on
planer bed.
(WITH QUIK-SET ADJUSTMENTS)
Planer bed rollers are adjusted to the proper height with
a quik-set
handle mounted on the right side of the planer
bed. The height of the rollers in relation to the bed sur-
face
is indicated by a graduated dial and pointer on the
qUik-set handle. If
table rollers do not correspond with
the height
indicator scale, adjustments can be made' by
loosening the set screw (26) fig. 4 in the
roller adjusting
arms. Set indicator pointer
at zero on the gauge and
turn adjusting screws (27) until the bed rollers are level
with the
planer bed. To plane rough lumber, set quik-set
indicator on
.030", for medium rough .010" to . 015" and
for finished lumber .000" to .010". Set the rollers high
enough
so that the lumber will feed through the machine
without hesitation.
POWER DRIYEN FEED ROLLS:
The power driven corrugated infeed roller (7) and smooth
outfeed
roller (25) are gear driven through Y-belts ar-
rangement from cutterhead shaft. The feed roller bearing
housings
are floating type and held against the feed roller
adjusting screws (14)
by means of adjustable pressure
springs (22). The feed rollers should be adjusted
to set
approximately 1/ 16" below arc of the cutterhead knives.
A
gauge or block may be used to assure proper height.
To set feed rolls, lower planer bed about 3" below arc of
cutterhead. Place gauge or wooden block directly under
cutterhead
and turn head until one knife is down. Raise
planer bed until block is 1/ 16" below knife edge. Check
the
roller to see that each end is the same. Too much pres-
sure on infeed
corrugated roller will leave markings on
material. Too little pressure
will restrict feed.
CHIPBREAKER:
The chipbreaker is a three piece type which mounts and
adjusts concentric with cutterhead.
The chipbreaker ad-
justing screws (6) should be adjusted to allow chipbreaker
to set 1/16" below level of infeed corrugated feed roller.
PRESSURE BAR:
The pressure bar is a three piece type which mounts and
adjusts concentric with cutterhead. The pressure bar
should be set equal to the arc of the cutterhead. One

method is to feed a wide board about four feet long half
way through the machine. Stop the feed with the clutch
and
set the holddown bar so that it just touches the board.
To set the pressure bar, loosen both top and bottom lock
nuts on adjusting studs (2 4 ), adjusting the bar with the
adjusting bar and lock
in place with the locking nuts.
Remember, the
press ure bar is the most IMPORTANT ad-
justment on the Planer. If the pressure bar is too high,
cutterhead knives will snipe beginning end
af material;
if
set too low, the material will not feed through machine.
MATERIAL THICKNESS GAUGE:
To set the indicator on the material thickness scale (11) to
indicate properly after changing knives, loosen the screw
in the planer bed that holds the brass pointer and set to
the thickness the material measures when planed or fed
through the machine.
The hole that mounts the brass
pointer
is slotted and will permit proper adjustment.
CUTIERHEAD:
The cutterhead is equipped with three knives held in posi-
tion with the lock
shims and set screws (18). Knives must
be adjusted to set evenly and level in the cutterhead.
Before removing 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
"f 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
OPERATING INSTRUCTIONS
raised or lowered, the feed rollers, chipbreaker and pres-
sure
bar should be adjusted accordingly. Knives should
not protrude more than
3/32" beyond radius of cutter-
head. 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 setting 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
cutterhead. Next, tighten the center knife locking
shim
bolt. Set the other knives in the cutterhead before tighten-
ing remainder
of the shim bolts. After the 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 vibration or uneven knife
height.
KNIFE CARE:
VERY IMPORTANT-knives must be kept sharp. The knives
do all 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.
Operating
and Safety
Instructions
1. Be s ure th e machine frame is electrically grounded.
2.
Remove or fasten loo se articles of clothing such as necktie, sleeves, coat, etcetera.
3. Remove finger rings and watch.
4. U se a safety face shie ld, goggles or glasses to protect eyes.
S. Keep the f loor around th e machine clean and free from scraps, sawdust, oil or grease to minimize the danger
of s lippin g.
6. Before
starting the planer:
a. C lear machine and table area of dust, chips, tools or foreign matter.
b. Check knives for sharpenss. Dull blades can cause pounding, kickbacks and poor planing.
c. Check the knives for cracks and nicks and that they are securely locked in the cutterhead. Broken or
loose knives can be thrown out of the machine causing severe or fatal injury.
d. Oleck for the proper setting of the infeed rollers, chip breaker, pressure bar and out feed rollers.
Improper settings can cause kickbacks and poor planing.
e. Check for proper direction of rotation of the cutterhead.
f. '· Iake sure all guards are in place and securely fastened.
7. Do not stand or walk directly behind the machine when it is running. The direction of cutterhead rotation
throws chips and foreign material from the rear of the machine.
8.
Check the material thickness, depth of cut desired and the machine capacity. Never overload the planer
by tryin g to cut beyond its capacity .
9.
When feeding material into the machine, stand to the side nearest the switch and never behind the board.
Kickbacks can cause
serious injury.
10. In case of a jam-up or stopping material part way through the cut -- stop the machine, wait until the
cutterhead is completely stopped and lower ~le table to clear the work. Attempting removal before the
cutterhead is stopped can cause kickbacks. Never attempt to force the work through the machine. If the
material does not feed properly, stop the machine and correct the cause. On planers equipped with a feed
reversing switch, a jam-up or stopping of the board may be cleared by reversing the feed direction.

OPERATING INSTRUCTIONS
11. Never feed two boards through a planer with solid infeed rollers at the same time (side-by-side or stacked).
Kickback can result causing serious injury. If your machine is equipped with sectional infeed roll and
chipbreaker, side-by-side feeding of narrow boards can be done safely.
12. Extra care should be used in feeding short boards. Use another piece of equal thickness in back of the
first board to follow it through the planer. The shortest board that can be fed through is one which'has
a
length 1/2" greater than the span between theinfeed and outfeed rollers.
13. If leaving the machine area, turn the machine off and wait until all moving parts stop before departing.
14. Give the work you're doing your undivided attention. Looking around, carrying on a conversation and
"horse , play" are careless acts that can cause serious injury.
15. Stop tIle machine when ,making adjustments and disconnect it from its power source when adjusting, replacing
and regrinding the cutterhead blades or performing any maintenance.
