Warning

As with all machines, there is a certain amount of hazard involved with the use of this planer. Use the
machine with the respect and caution demanded where safety precautions are concerned. When normal
safety precautions are overlooked or ignored, personal injury to the operator can result.
Read, understand and follow the safety and operating instructions found in this manual. Know the
limitations and hazards associated with this machine.
Electrical grounding. Make certain that the machine frame is electrically grounded and that a ground
lead is included in the incoming electrical service. In cases where a cord and plug are used, make certain
that the grounding plug connects to a suitable ground. Follow the grounding procedure indicated in the
National Electrical Code.
Eye safety. Wear an approved safety shield, goggles, or glasses to protect eyes. (NOTE: Common
eyeglasses are only impact-resistant, they are not safety glasses.)
Personal protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll
up sleeves above the elbows. Remove all loose outer clothing and confine long hair. Protective type
footwear should be used. Where the noise exceeds the level of exposure allowed in Section 1910.95 of
the OSHA Regulations, use hearing protective devices. Do not wear gloves.
Guards. Keep the machine guards in place for every operation for which they can be used. If any guards
are removed for maintenance, DO NOT OPERATE the machine until the guards are reinstalled.
Placement. Place machine so that potential kickback area is not in line with aisles, doorways, wash
stations, or other work areas.
Work area. Keep the floor around the machine clean and free of scrap material, saw dust, oil and other
liquids to minimize the danger of tripping or slipping. Be sure the table is free of all scrap, foreign material
and tools before starting to cut. Make certain the work area is well lighted and that a proper exhaust
system is used to minimize dust. It is recommended that anti-skid floor strips are used on the floor area
where the operator normally stands and that each machine’s work area be marked off. Provide adequate
work space around the machine.
Avoid accidental starting: Make certain motor switch is in off position before connecting power to the
machine.
Operator position. Maintain a balanced stance and keep your body under control at all times. Stand to
one side out of line with the table and make sure no one else is standing in line with the table.
Housekeeping. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap,
and cleaning rags away from the machine
Careless acts. Give the work you are doing your undivided attention. Looking around, carrying on a
conversation, and “horseplay” are careless acts that can result in serious injury.
Disconnect machine before performing any service or maintenance or when changing blades. A
machine under repair should be RED TAGGED to show it should not be used until the maintenance is
complete.
Maintain tools in top condition. Keep tools sharp and clean for safe and best performance. Dull tools
increase noise levels and can cause kickbacks and glazed surfaces. Check the condition and adjustment
of the tools before making any cuts. Follow the sharpening instructions on knife grinding and jointing,
installing and adjustments.

Hand safety. Keep hands outside the machine. NEVER reach under the guards to try to clear stock that
stops feeding. Do not clear chips and sawdust with hands; use a brush. Do not have any part of the
hands under that part of the board that is over the table when starting a cut; the infeed roll will engage the
board and force it down against the table causing a pinching action. Do not operate machine while the
gear cover is open.
Cutterhead rotation: Be sure cutterhead rotates under power in a counterclockwise direction when
viewed from the main drive motor side.
Material condition: Do not plane boards with loose knots or with nails or any foreign material on its
surface. Knife impact on these objects can cause the knives to be pulled out and cause them to shatter
against the chipbreaker or pressure bar. Twisted, warped, or in wind stock should first be jointed on one
surface before attempting to plane a parallel surface on the planer. Serious stock flaws cannot be
removed by use of a planer alone.
Machine adjustments: Make all machine adjustments with power off except feed rate.
Job completion. If the operator leaves the machine area for any reason, the planer should be turned
"off" and the cutterhead should come to a complete stop before his departure. In addition, if the operation
is complete, he should clean the planer and the work area. Never clean the planer with power "on" and
never use the hands to clear sawdust and debris; use a brush.
Replacement parts. Use only Powermatic or factory authorized replacement parts and accessories;
otherwise the warranty and guarantee is null and void.
Misuse. Do not use this Powermatic planer for other than its intended use. If used for other purposes,
Powermatic disclaims any real or implied warranty and holds itself harmless for any injury or damage
which may result from that use.
If you are not thoroughly familiar with the operation of planers, obtain advice from your supervisor,
instructor or other qualified person.
Drugs, alcohol, medication. Do not operate this machine while under the influence of drugs, alcohol, or
any medication.
Health hazards. Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
* Lead from lead-based paint.
* Crystalline silica from bricks and cement and other masonry products.
* Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment,
such as those dust masks that are specifically designed to filter out microscopic particles.

Familiarize yourself with the following safety notices used in this manual:
This means that if precautions are not heeded, it may result in minor injury and/or
possible machine damage.
This means that if precautions are not heeded, it may result in serious injury or possibly
even death.

Assembly
Tools required for assembly:
Forklift or hoist with slings
Pliers
Open-End Wrenches (10,12,19mm) – provided
Hex Wrenches, 4 and 5mm – provided
Remove the screws holding the planer to the
pallet and use a forklift or hoist to lift the planer
off the pallet. Forks and straps should always be
placed under the four lifting handles when lifting
this machine (Figure 5). The lifting handles can
be pushed back in when not in use.
The planer should be operated in a well-lit area
with a sturdy floor and good ventilation. It can be
rolled on its casters to the desired location.
Tighten the lock knob (Figure 6) to prevent
movement during operation or adjustments.

Figure 5

Exposed surfaces, such as tables, rollers,
cutterhead, etc., have been given a protective
coating at the factory. This should be removed
with a soft cloth moistened with a good
commercial solvent. Do not use acetone,
gasoline, lacquer thinner, or other solvents with
a low flash point. Do not use an abrasive pad
because it may scratch the polished cast iron
surfaces.
Figure 6
Use care when cleaning
around the cutterhead area – knives are
extremely sharp!

Knife Gauge (model 209 only)
Place the two gauge blocks on the ends of the
shaft (Figure 7) and use a pliers to press the
four e-rings into the grooves on each side of the
blocks.

so the handwheel slips over the

2. Place flat washer and hex nut on shaft and
tighten with 19mm wrench.
3. Mount the handle into the threaded hole in
the handwheel, and tighten with a 12mm
wrench placed over the flat on the handle.

Extension Tables
1. Mount a cast iron table to the edge of the
main table with three M8 x 25 hex cap
screws (Figure 9) using a 12mm wrench. Do
not fully tighten yet.
2. The extension table must be leveled with the
main table. Place a straight edge (such as a
jointed board) across both tables.
3. Insert three socket set screws with a 4mm
hex wrench, and screw them in or out as
needed until tables are level.
4. Securely tighten the hex cap screws.

Figure 9

5. Mount the second extension table to the
opposite side of the planer table, using the
same procedure.

Dust Hood
Mount the hood to the rear of the head casting
with six M6 x 12 hex cap screws and six 1/4" flat
washers (Figure 10), with a 10mm wrench.
It is recommended that you use a dust collection
system with this planer. If you are not using a
dust collection system, do not attach the dust
hood to the planer, as the accumulation of dust
inside the hood may create a safety hazard, or
eventually cause jamming of the rollers.

Figure 10

Electrical Connections
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. The
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
A power plug is not provided with the 209
planer. You may either connect one or "hardwire" the machine directly to your electrical
panel provided there is a disconnect near the
machine. Consult electrical schematics on
pages 35-37 for further clarification of wiring
setup.
This machine must be grounded. Grounding
provides a path of least resistance to help divert
current away from the operator in case of
electrical malfunction.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the machine.

Extension Cords

Recommended Gauges (AWG) of Extension Cords
Extension Cord Length *

The use of an extension cord is not
recommended for this machine, but if one
proves necessary make sure the cord rating is
suitable for the amperage listed on the
machine's motor plate. An undersize cord will
cause a drop in line voltage resulting in loss of
power and overheating.
The chart in Figure 11 shows the correct size
cord to use based on cord length and motor
plate amp rating. If in doubt, use the next
heavier gauge. The smaller the gauge number
the heavier the cord.

Figure 11

Disconnect machine from
power source before making any adjustments (except feed rate).

Belt Tension
Inspect the tension of the belts frequently during
the first few times you use the planer. Belts often
stretch during this trial period. If they require
tightening, proceed as follows:
1. Remove the belt guard and the rear panel.
2. Loosen the bottom nuts on the motor
adjustment screws (Figure 12) with a 19mm
wrench.

Figure 12

3. Turn the top nuts to lower the motor plate,
which will increase the belt tension.
4. Proper tension is achieved when there is
slight deflection in the belt midway between
the pulleys, using moderate finger pressure.
5. Tighten the bottom nuts (Figure 12).

Table Rollers
Your planer is supplied with two table rollers
(Figure 13) which turn as the stock is fed into the
machine, thus reducing friction. It is not possible
to give exact dimensions on the proper height
setting of the table rollers because each type of
wood behaves differently. As a general rule,
however, when planing rough stock the table
rollers should be set at high position.

Figure 13

When planing smooth stock the rollers should be
set at low position.
NOTE: When raising the roller higher above the
table, the range is from .003" to .006" (Figure
14).
The table rollers are factory set for average
planing and are parallel to the table surface. If
you desire to adjust the table rollers higher or
lower, proceed as follows:
1. Disconnect machine from power source.

Figure 14

2. Lay a straight edge across both rollers.
3. On one side of the table, loosen the set
screws (Figure 15) with a 3mm hex wrench,
and turn the eccentric shafts to raise or
lower the rollers.
4. When proper height is achieved, tighten set
screws.
5. Adjust the rollers from the opposite side of
the table in the same manner.
IMPORTANT: Be sure that the height of front
and rear rollers are the same. The table rollers
must always be set parallel to the table.

Cutterhead

Figure 15

Although your planer was carefully adjusted at
the factory, it should be checked before being
put into operation. Any inaccuracies due to
rough handling in transit can be corrected by
following the directions in this manual.
To check the adjustments you will need a knifesetting gauge (provided), feeler gauges, and a
dial gauge or home-made gauge block made of
hardwood. This gauge block can be made by
following the dimensions shown in Figure 16.
You will also need to remove the belt guard, so
you can rotate the cutterhead using the pulley.

Knife Adjustments (Model 209 only)

Figure 16

When checking or adjusting cutterhead knives
on the model 209 Planer, proceed as follows:
1. Disconnect machine from power source.
2. Remove the six screws and upper cover
(Figure 17).
3. To check and adjust knives, use the
provided knife setting gauge and check all
four knives. Knives should just contact the
bottom of the center protrusion (D, Figure
18) of the knife gauge. Make sure the feet of
the knife gauge sit solidly upon the
cutterhead, and that its shaft is parallel to
the cutterhead (see Figure 19).

Figure 17
12

4. If an adjustment to one or more of the knives
is necessary, slightly loosen the knife gib (E,
Figure 18) by turning the six screws (F,
Figure 18) into the gib (i.e. clockwise, when
facing the screw heads) with a 12mm hex
wrench. Turn the screws just enough to
relieve stress in the cutterhead without
disturbing the setting of the knives. Do this
for all four knives at the same time.
5. With the knife setting gauge (C, Figure 18)
in place over a knife (G, Figure 18), continue
to loosen the screws (F, Figure 18) until the
springs (H, Figure 18) begin raising the
knife. When knife comes in contact with the
center protrusion of the gauge, snug the gib
by lightly backing out the six screws (F,
Figure 18) against the slot (i.e. counterclockwise).
NOTE: At this time, tighten the knife into the
slot just enough to hold knife in position.
6. If additional knives must be reset, repeat
step 5.

Figure 18 – Model 209 only

7. After all knives are set with screws just
snug, back out and tighten the six screws (F,
Figure 18) against the slot starting with the
end screws first, then the center screws,
until the knife is securely held in the
cutterhead. Tighten the remaining three
knives in the same manner.
After setting or installing
knives, re-check all gib screws. Loose gib
screws can result in knives being thrown out
of the cutterhead, causing severe damage to
the machine and possible serious or fatal
injury to the operator or bystanders.

Figure 19 – Model 209 only

Replacing and Re-setting Knives
(Model 209 only)
If the knives are removed for sharpening, care
must be exercised in replacing and re-setting
them. Proceed as follows:
1. Disconnect machine from power source.
2. Remove six screws and upper cover (see
Figure 17).
3. To remove knife, loosen the gib (E, Figure
18) by turning the six gib screws clockwise.
Remove gib, knife and springs.
4. Remove the remaining three knives in the
same manner.
5. Thoroughly clean the knife slots, gibs,
springs and gib screws. Check the gib
screws; if the threads appear worn or
stripped or if the heads are becoming
rounded, replace them.
13

6. Inspect the cutting edge of the knives for
nicks or wire edge. Hone the knives slightly
using a stone or if the knives are to be
sharpened, maintain a cutting angle of 35
degrees.
7. Insert springs, knife and gib into slot of
cutterhead. Back out screws just enough to
hold the knife in the cutterhead.
8. Place knife setting gauge (Figure 19) over
knife.
9. While holding down the knife gauge, loosen
all six screws by turning them into the gib
until the cutting edge of the knife comes in
contact with the protrusion of the gauge.
Snug up the gib by slightly backing out the
six screws against the slot.

Figure 19 repeated

NOTE: At this time, only tighten the knife
into the slot just enough to hold the knife in
position.
10. Replace and re-set the other three knives in
the same manner.
11. After all four knives are set with the screws
just snug, back out and tighten the six
screws against the slot starting with the end
screws first and then the center screws until
the knife is securely held in the cutterhead.
Tighten the remaining three knives in the
same manner.
After replacing and checking
knives, check again carefully. Make certain
the direction of knives is correct and all 24
gib screws are tightened securely.

Replacing or Rotating Knife Inserts
(Model 209HH only)
The knife inserts on the model 15HH are foursided. When dull, simply remove each insert,
rotate it 90° for a fresh edge, and re-install it.
Use the provided screwdriver with the socket
adaptor to remove the knife insert screw. See
Figure 20. It is advisable to rotate all inserts at
the same time to maintain consistent cutting.
However, if one or more knife inserts develops a
nick, rotate only those inserts that are affected.
Each knife insert has an etched reference mark
so you can keep track of the rotations.
IMPORTANT: When removing or rotating
inserts, clean saw dust from the screw, the
insert, and the cutterhead platform. Dust
accumulation between these elements can
prevent the insert from seating properly, and
may affect the quality of the cut.

Figure 20 – Model 209HH only
Before installing each screw, lightly coat the
screw threads with machine oil and wipe off any
excess.
Securely tighten each screw which holds the
knife inserts before operating the planer!
Make sure all knife insert
screws are tightened securely. Loose inserts
can be propelled at high speed from a
rotating cutterhead, causing injury.

Work Table Parallel to Cutterhead
The work table is set parallel to the cutterhead at
the factory and no further adjustment should be
necessary. If your machine is planing a taper,
first check to see if the knives are set properly in
the cutterhead. Then check to see if the work
table is set parallel to the cutterhead. Proceed
as follows:
1. Disconnect machine from power source.
2. Place the gauge block (Figure 21) on the
work table directly under the edge of a knife
or knife insert as shown. Make slight contact
with the knife edge by gently raising the
table.

Figure 21

3. Move the gauge block to the opposite end of
the work table. The distance from the work
table to the edge of the knife should be the
same on both ends of the knife.
If the work table is not parallel to the cutterhead,
perform the adjustment procedure as follows:
1. Disconnect machine from power source.
2. Remove bolts holding the planer to the
stand. Tilt planer on its side to expose
underside of base (Figure 22).
3. Remove bolt (A, Figure 22) and loosen bolt
(B-Figure 22) which will allow you to move
the idler sprocket assembly (C, Figure 22)
far enough to release tension on the chain.

Figure 22

4. Remove the chain from the particular
sprocket on the corner of the base that you
need to adjust.
5. Turn the sprocket by hand to bring that
corner into adjustment with the other three
corners. NOTE: Turning sprocket clockwise
will increase the distance between the
working table and the head casting;
counterclockwise will decrease the distance.
This adjustment is very sensitive and it
should not be necessary to turn the sprocket
more than one or two teeth.
6. When adjustments are correct, replace
chain around corner sprocket, slide idler
sprocket (C-Figure 22) back to re-tension
chain, tighten bolt (B, Figure 22) and insert
and tighten bolt (A, Figure 22).

Anti-Kickback Fingers
The anti-kickback fingers (A, Figure 23) are an
important safety feature, as they help prevent
kickback of stock. They operate by gravity and
should be inspected frequently to make sure
they re free of gum and pitch, so that they move
independently and operate correctly.

Infeed and Outfeed Roller Spring
Tension
The infeed roller (B, Figure 23) and outfeed
roller (F, Figure 23) are those parts of your
planer that feed the stock while it is being
planed. The infeed roller and the outfeed roller
are under spring tension and this tension must
be sufficient to feed the 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.

Figure 24

To adjust the spring tension of the infeed and
outfeed rollers, turn screws (Figure 24) with a
hex wrench. Turn screws on both ends of
infeed/outfeed rollers in the same manner.

Height of Infeed Roller, Chipbreaker,
Pressure Bar and Outfeed Roller
The infeed roller, chipbreaker, pressure bar and
outfeed roller are adjusted at the factory. The
height relationship between these items and the
cutterhead is crucial for accurate and safe
planing. The infeed roller, chipbreaker, pressure
bar, and outfeed roller should be set .020"
(0.5mm) below the cutting circle. See Figure 25.
If any adjustments are necessary for the infeed
roller, chipbreaker, pressure bar or outfeed
roller, they should be done carefully. Use the
following steps as an example of procedure.
NOTE: This procedure uses a home-made
gauge block and feeler gauges, which should be
sufficient for most planer operations. If extra
precise measurements are desired, however,
use a dial indicator device. A bed and feed roller
gauge with dial indicator (stock # 2230002) is
available as an accessory for this machine, and
may be purchased from WMH Tool Group.
Figure 25

Outfeed Roller Height
1. Disconnect machine from power source.
2. Make sure the knives are set properly as
previously
explained
under
"Knife
Adjustment."
3. Place the gauge block (J, Figure 26) on the
table directly beneath the cutterhead (D,
Figure 26).
4. Using a 0.02" (0.5mm) feeler gauge (K,
Figure 26) placed on top of the gauge block,
raise the work table until the knife just
touches the feeler gauge when the knife is
at its lowest point. Do not move the work
table any further until the outfeed roller is
adjusted.

Figure 26

5. Remove the feeler gauge and move the
gauge block (J, Figure 27) under one end of
the outfeed roller (F, Figure 27). The bottom
of the outfeed roller should just touch the top
of the gauge block. If an adjustment to the
outfeed roller is necessary, loosen the lock
nut (L, Figure 27) and turn screw (M, Figure
27) until the outfeed roller just touches the
gauge block. Then tighten lock nut (L, Figure
27).

6. Check and adjust the opposite end of the
outfeed roller in the same manner.

Infeed Roller Height

Figure 27

Use the exact same procedure for checking the
infeed roller as you did for the outfeed roller,
except use a .004" (0.1mm) feeler gauge atop
the gauge block. If adjustment is necessary, use
the lock nut and screw on each end of the infeed
roller.

Chipbreaker Height
The chipbreaker breaks off the larger chips
before the stock reaches the cutterhead. Use
the gauge block and a .004" (0.1mm) feeler
gauge to check the height of the chipbreaker,
following the same procedure as above. If
adjustment is needed:
1. Remove top cover.
2. Loosen the lock nuts (A, Figure 28) at both
ends of the chipbreaker, and turn the set
screws to raise or lower the chipbreaker as
needed. The set screws should be turned
the same amount.

Figure 28

3. When the chipbreaker contacts the gauge
block, tighten both lock nuts (A, Figure 28).

Pressure Bar Height
The pressure bar prevents the stock from lifting
after it passes under the cutterhead. Check the
height of the pressure bar with your gauge block
and a .008" (0.2mm) feeler gauge. If adjustment
is needed:
1. Remove top cover.
2. Loosen the lock nuts (B, Figure 29) on both
ends of the pressure bar and turn the set
screws as needed.

3. When the pressure bar contacts the top of
the gauge block, tighten the lock nuts (B,
Figure 29).

Figure 29

Chip Deflector
The chip deflector (C, Figure 29) keeps wood
chips from falling into the outfeed roller. The
deflector should be set approximately 1/16" from
the tip of the knives. Make sure the deflector's
front edge is beveled to match the shape of the
cutterhead.

Feed Speed Control
Your machine is equipped with a spiral, serrated
infeed roller and a solid steel outfeed roller.
When the feed rollers are engaged, they turn to
feed the stock. The feed rollers slow
automatically when the machine is under heavy
load for best planing in all conditions. The feed
rollers are driven by chains (A, Figure 30) and
sprockets (B, Figure 30) which take power
directly from the cutterhead through the oil bath
gear box (C, Figure 30).

Figure 30

The gear box has two feed speeds. These are
set by pulling out or pushing in the shift lever (D,
Figure 30) while the machine is running. The
feed speed range is shown in Figure 31.
Do not attempt to change
feed speed while stock is passing through
the machine. Damage to the gearbox may
result.

Changing Accessories for Lowest
Feed Speed
The lowest feed speeds for your planer (16.2
fpm and 20.7 fpm) can be obtained by replacing
the lower (gear shaft) sprocket and its chain
(Figure 31).
A low speed gear kit, consisting of a 50P chain
and 12T sprocket, is provided with your planer.
To change the sprocket and chain on your
machine, proceed as follows:

Figure 31
18

1. Disconnect machine from power source.
2. Remove the three hex cap screws and
washers (E, Figure 30).
3. Remove the three sprockets (B, Figure 30)
from the infeed roller, outfeed roller and the
gear shaft at the same time.
4. When all sprockets have been removed,
replace the gear shaft sprocket (G, Figure
31) and its chain (F, Figure 31) with those of
a different size.
5. Mount all three sprockets and chains to their
shafts, and tighten all hex cap screws and
washers (E, Figure 30).

Return Rollers
The two return rollers on top of the machine
serve as a convenient rest for stock. They save
time and motion for the operator as the stock is
returned to the infeed side.

Depth of Cut
The cutting depth scale is a combination
inch/metric scale (A, Figure 32), with a cutting
range from 0 to 8" (204mm). The distance of
upward or downward movement is controlled by
the handwheel (B, Figure 32). One revolution of
the handwheel is .059" (1.5mm). Before moving
the table up or down, loosen the lock nuts (C,
Figure 32). After obtaining proper table position,
tighten the lock nuts (C, Figure 32).
Figure 32

Maximum depth of cut is 1/8". A limiter (D,
Figure 32) is provided to limit the depth of cut on
full width planing from 3/16" to 1/8".
The depth scale and pointer are adjustable and
should be checked for accuracy. Proceed as
follows:
1. Connect power, and turn on the planer.
2. Take a scrap board and measure its exact
thickness with calipers.
3. Raise or lower the table so the scale reads
the thickness of the board minus 1/16".
Feed the board through the planer.
4. Move the table up another 1/16". Flip the
board over and plane the other side.
5. Measure the board with calipers and
compare with the depth scale on the planer.
If the scale needs adjustment, loosen the
screws and shift the scale up or down as
needed. Tighten screws when finished.

Lubrication

Maintenance
power source
maintenance.

The bearings on the cutterhead are factory
lubricated and sealed for life – no lubrication is
required.

Disconnect machine from
before performing any

GEARBOX LUBRICANT
The lubricant in the gear box must be replaced
every 2,500 hours. Multi-purpose gear box
lubricant will be suitable.

Periodic or regular 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 worn
or loose electrical connections.

To replace the lubricant:
1. Remove the drain plug (A, Figure 33) with a
14mm wrench, and remove filler cap (BFigure 33). Drain dirty oil thoroughly.

Buildup of sawdust and other debris can cause
your machine to plane inaccurately. Periodic
cleaning is not only recommended but
mandatory for accurate planing.

2. Tighten the drain plug (A, Figure 33).
3. Fill with clean lubricant through hole (B,
Figure 33).

Close-fitting parts, such as the cutterhead slot
and gibs, should be cleaned with a cloth or
brush and non-flammable solvent, and freed
from clinging foreign matter.

4. Tighten filler cap (B, Figure 33).

Remove resin and other accumulations from
feed rollers and table with a soft rag and nonflammable solvent.
Periodically check all the chains for proper
tension and adjust accordingly if required.
TIP: If a foreign object nicks the knives, 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 should no longer be noticeable.
The table should be kept clean and free of rust.
Some users prefer a paste wax coating. Another
option is talcum powder applied with a
blackboard eraser rubbed in vigorously once a
week; this will fill casting pores and form a
moisture barrier. This method provides a table
top that is slick and allows rust rings to be easily
wiped from the surface. Important also is the fact
that talcum powder will not stain wood or mar
finishes as wax pickup does.
