Page 9
Electrical Connections
El ectrical conn ections must be
made by a qualified electrician in compliance
with all relevant codes. The machine mu st be
properly grounded to help prevent electrical
shock and possible fat al injury.
A power plug is not provided wit h the 208 planer.
You may either connect one or "hard-wire" the
machine dir ectly to your el ectrical panel provided
there is a disconnect near the machine. Consult
the wiring diagrams on pages 32-35 for further
clarific ation of wiring setup.
This machine must be grounded. Grounding
provides a path of least resistance to hel p 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.
Extens ion Cords
The use of ex tension cords is discouraged; try to
position the machine within reach of the power
source. If an extension cord becomes nece ssary,
make sure the cord rating is suitable for the
amperage list ed on the mac hine's motor pl ate. An
undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
Figure 7
The chart i n Figure 7 shows the cor rect size cord
to use based on cord l ength and m otor pl ate amp
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number the heavier the cord.
Adjustments
Belt and Pulleys
1. Using a straight edge, align the motor pulley
(A, Fig. 8 ) and cutterhead pulley (B, Fig. 8).
The motor plate can be moved for al ignment
by loosening the set screws (C, Fig. 9) in the
motor plate.
Figure 8
Figure 9

Page 10
2. Check bel t tensi on. Pr oper tensi on is obtai ned
when there is approx imately 1/ 4” deflection of
the center span of the pulleys using light
finger pressure (Fig. 10).
3. If adjustment of belt tension is necessary,
loosen one pair of hex nuts (E & F, Fig. 11)
and turn the other pair to raise or lower the
motor plate. Re-tighten nuts.
Table Rollers
Figure 10
Figure 11
Overview
Your planer is supplied with two table rollers
(A, Fig. 12) which turn as the stock i s fed int o the
planer, thus reduc ing friction. It is not possible t o
give exact dimensions on the proper height setting
of the table rollers because each type of wood
behaves diff erently.
As a general rule, however, when planing rough
stock, the table rollers should be set at high
position. When planing smooth stock the rollers
should be set at low position.
Figure 12
10
Page 11
Note: When raising the roller higher above the
table, the available range is from .003” to .006”
See Fig. 13.
The table rollers are factory set for average
planing and are par allel t o the table surfac e. If you
desire to adjust the table rollers higher or lower,
proceed as follows:
1. Disconnect machine from power source.
2. Lay a straight edge (B, Fig. 14) across both
rollers.
3. On one side of the table, loosen the screws
(C, Fig. 14) with a hex wrench, and turn the
eccentri c shafts (D, Fig. 14) to rai se or lower
the rollers.
Figure 13
4. When the proper height is achieved, tighten
screws (C, Fig. 14).
5. Adj ust the r oll ers from t he opposit e 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.
Adjusting Table Extension Rollers
1. Pl ace a str aight edge ov er t he extensi on rol l er
and the table, as shown in Fig. 15, to make
sure the extensi on roller and table are at the
same height. If necessary, adjust the table
extension roll er s as f ollows:
2. Loosen the screws and washers (A, Fig. 15)
to move the extension roller to the proper
position, then retighten the screws.
3. Adjust both front and rear extension rollers in
the same manner.
Figure 14
Figure 15

Page 12
Adjusting Depth of Cut
The cutting depth scale (A, Fig. 16) is a
combination i nch/metric scale with a cutt ing range
from 0 to 8” (204mm). T he distance of upward or
downward movement is controlled by the
handwheel (B, Fig. 16). One revolution of the
handwheel is .059” (1.5mm). Before moving the
table up or down, l oosen the lock nuts (C, Fig. 16).
After obtaining the proper table position, tighten
the lock nuts (C, Fig. 16).
Always tighten the lock nuts
before operating the planer.
Cutterhead Adjustment
Overview
Although your planer was carefully adjusted at t he
factory, it shoul d be checked bef or e being put i nto
operation. A ny inacc uracies due to rough handl i ng
in transit can easily be corrected by following
these directions.
To check the adjustm ents you will need a straight
edge, feeler gauge, and a homemade gauge bloc k
made of hardwood. This gauge block can be
made by following the dimensions shown in
Figure 17.
Figure 16
Knife Adjustmen t (Mod el JWP- 208 on ly)
When checki ng or adjusting the cutterhead k nives,
proceed as follows:
1. Disconnect machine from power source.
2. Remove the six screws (A, Fig. 18) and
remove upper cover (B, Fig. 18).
3. To check and adj ust knives, use the prov ided
knife gauge (F ig. 19 & 20) and check all four
knives. Kniv es should just contact the bot tom
of the center protrusion (D, Fig. 19) of the
knife gauge.
4. If an adjustm ent to one or m ore of t he knives
is necessary, slightly loosen the knife gib
(E, Fig. 19) by turning the six locking screws
(F, Fig. 19) into the gib. Turn the screws just
enough to relieve stress in the cutterhead
without distur bing t he setting of the k nives. Do
this for all f our knives at the same time.
5. With the gauge in place over a knife
(G, Fig. 19) continue to loosen the locking
screws (F, Fig. 19) until the springs
(H, Fig. 19) begi n r aisi ng the knife. When knif e
comes int o contact with the cent er protrusion
(D, Fig. 19) of the gauge, snug up the gib by
lightly backing out the six locking screws (F,
Fig. 19) agai nst the slot.
Figure 17
Figure 18
12
Page 13
NOTE: At this time, only tighten the knife in
the slot just enough to hold knife in position.
6. If additional knives must be reset, repeat
step 5.
7. After all four knives are set with screws just
snug, back out and tighten the six locking
screws (F, Fig. 19 & 20), against the slot
starting with the end screws first, then the
center screws, unt il the knif e is securely held
in the cutterhead. Tighten remaining three
knives in the same manner.
Important: Double check all screws for tightness.
Replacing & Resetting Knives (Model
JWP-208 only)
If the knives are removed for sharpening, care
must be exer cise in replaci ng and resetting t hem.
Proceed as follows:
1. Disconnect machine from power source.
2. Remove six screws and upper cover (see
Fig. 18).
3. To remove knife, loosen the gib (E, F ig. 19) by
turning the si x l ocking screws (F , Fi g. 19) into
the gib. Remove gib (E, Fi g. 19), knife (G, Fi g.
16) and spring s (H, F ig. 19). NOTE: The inner
two springs m ay pop out when the knif e and
gib are removed.
Figure 19 – JWP-208 only
4. Remove the remaining three knives in the
same manner.
5. Thoroughl y clean t he knif e slots, gibs, spri ngs
and locking scr ews. Chec k the locking screws;
if the t hreads appear worn or stri pped or if t he
heads are becoming r ounded, replace them.
6. Inspect the cut ting edge of the knives for nicks
or wire edge. Hone the kniv es sl ightly usi ng a
stone, or if the knives are to be sharpened,
maintain a cutti ng angle of 35 degrees.
7. Insert springs, knives and gib into slot of
cutterhead. Back out locking screws just
enough to hold the knife in the cutterhead.
8. Place knife gauge (C, Fig. 19) over knife.
9. While holding down on the knife gauge,
loosen all six locking screws (F) by turning
them into the gi b (E) until cutting edge of knif e
comes into contact with the protrusion (D) of
the gauge. Snug up the gi b by slightly backing
out the six locki ng screws again st the slot.
Note: At this time, only tighten the knife into the
slot just enough t o hold the knife in position.
Figure 20 – JWP-208 only
13
Page 14
10. Replace and reset the other three knives in
the same manner.
11. After all four knives are set with the screws
just snug, back out an d ti ghten the six screws
(F) 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
twenty-four locking screws are tightened
securely.
Replacing or Rotating Knife Inserts
(Model JWP-208HH only)
The knife inserts on the model JWP-208HH are
four-si ded. When dull, simpl y remove each insert,
rotate it 90° for a fresh edge, and re- install it.
Use the provided st ar point screwdriv er to remove
the knife insert screw. See Figure 20a. It is
advisable to r otate all inserts at the sam e 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 rem oving or rotating i nserts,
clean saw dust from the scre w, the i nsert, and t he
cutterhead platform. Dust accumulation between
these elements can prevent the insert from
seating properl y, and may affect the quality of the
cut.
Before installing each screw, l ightly coat the screw
threads with mac hine oil and wipe off any excess.
Securely ti ghten each screw which holds the knif e
inserts befor e oper ating the planer!
Make sure all knife insert
screws are tightened securely. Loose inserts
can be propelled at high speed from a rotating
cutterhead , cau sin g inju ry.
Checking Work Table Parallel to
Cutterhead
The work tabl e is set parall el to the c utterhead at
the factory and no further adjustment should be
necessary. If your machine is planing a t aper, first
check to see if t he knives are set properly in the
cutterhead. Then check to see if the work tabl e is
set parallel to the cutterhead. Proceed as follows:
Figure 20a – JWP-208HH only
14
Page 15
1. Disconnect machine from power source.
2. Place the gauge block (Figur e 21) on the work
table dir ectl y under the edge of a knife or knife
insert as shown. Make slight cont act with the
knife edge by gentl y raisi ng the table.
3. Move the gauge bloc k to the opposit e 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.
Adjusting Work Table Parallel to
Cutterhead
If the work table i s not parallel to the cutterhead,
perform the adjustm ent procedure as follows:
1. Disconnect the m ac hine from power source.
2. Til t planer on its side to ex pose underside of
base, as shown in Fig. 22.
3. Remove bolt (A, Fig. 22) and loosen bolt (B,
Fig. 22) which will allow you to move the idler
sprocket assembl y (C, Fig. 22) far enough to
release tension on the c hain.
4. Remove chain from the parti cular sprocket on
corner of base that m ust be adjusted.
Turn the sprocket by ha nd to bri ng t hat cor ner
into adjustment with the other three corners.
NOTE: Turning sprocket clockwise will
increase the distance between the working
table and headcasting; counter-clockwise will
decrease the distance. This adjustment is very
sensitive and it should not be necessary to
turn the sprocket m or e than one or two teeth.
5. When adjustments are correct, replace chain
around corner sprock et, slide sprock et (C, Fig.
22) back to re-tension chain, tighten bolt (B,
Fig. 22) and repl ace and tighten bolt (A, Fig.
22).
Know the Transmit ting Rolle r s of Y o ur P la ne r
A – Anti-Kickback Fingers
B – Infeed Roller
C – Chipbreaker
D – Cutterhead
D – Pressure Bar
E – Outfeed Roller
The infeed roller (B, Fig. 23) and outfeed roller
(F, Fig. 23) are those part s of y our planer that feed
the stock whil e it i s being planed. The i nfeed and
outfeed rollers 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 t he
board. The tensi on should be equal at both ends
of each roller.
Figure 21
Figure 22
Figure 23
15
Page 16
Anti-Kickback Fingers
The anti- kickback fingers (A, Fig 23) hel p prevent
kickback of stock. They operate by grav ity and it i s
necessary to inspect them occasionally to make
sure they are f ree of gum and pitch, so that t hey
move independently and operate correctly.
Adjusting Infeed & Outfeed Roller
Spring Tension
To adjust the spring tension of the infeed and
outfeed roller s, tur n screws (G & H, Fig. 24) with a
hex wrench. Turn screws on opposite end of
infeed/outfeed rollers in the same manner.
Figure 24
Figure 25
Height of Infeed Roller, Chipbreaker,
Pressure Bar & Outfeed Roller
The infeed r oller, chipbreaker, pr essure bar and
outfeed roller are adjusted at the factory. The
infeed roller and the chipbreaker should be set
at 0.004” (0.1mm) below the cutting circle; and
the outfeed roll er should be set at 0. 02” (0.5mm )
below the cutting ci r cl e. See Fig. 25.
If an adjustment to the infeed roller, c hipbreaker,
pressure bar or outf eed roller is necessary, use
the following steps as an example of procedure.
To check and adj ust the out f eed rol l er bel ow the
cutting circl e, proceed as follows:
1. Disconnect machine from power source.
2. Make sure the kniv es are adjusted properl y
as previously explained under “Checking &
Adjusting of Knives.”
3. Place the gauge block (J, Fig. 26) on the
table dir ectl y underneat h the cut ter head (D,
Fig. 26). Usi ng a 0.02” (0.5mm) feeler
gauge (K, Fig. 26) placed on t op of the
gauge block, raise the working table
until the knife just touches the feeler
gauge when the knife is at its lowest
point. Do not move the working table
any further until the outfeed roller is
adjusted.

4. Mov e t he gauge bl ock (J , F ig. 27) under one end
of the outfeed roll er (F, Fig. 27). The bottom of
the outf eed r oller should just touch the top of the
gauge block. If an adjustment to the outfeed
roller is necessary, loosen the lock nut (L, Fig
27) and turn screw (M, Fig. 27) until the outfeed
roller just touches the gau ge bl ock. Then t i ghten
lock nut (L, Fig. 27).
5. Check and adjust opposite end of the outfeed
roller in the same manner .
Figure 27
4. When the sprockets (B, Fig. 28) are
removed, replace the lower sprocket
which will be assembled on the gear
shaft.
5. Assemble the three sprockets and
chains to the shafts, and tighten the
hex cap screws (E, Fig. 28).
Return Rollers
The two return rollers on the 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.
Feed Speed Control
Your machine i s equipped wit h a spiral , serr ated
infeed roll er and a sol i d outf eed roll er. When the
feed rollers are engaged, they turn to feed the
stock. The f eed rollers slow autom atically when
the machine is under heavy load f or best planing
in all conditions. The feed rollers are driv en by
chains (A, Fig. 28) and sprockets (B, Fig. 28)
which take power directly from the cutterhead
through the oil bath gear box (C, Fig. 28).
The gear box has two feed speeds. These are
set by pulling out or pushi ng in the shif t lev er (D,
Fig. 28) whil e the machine is running. The f eed
speed range is shown in Fig. 29.
Changing Accessories for Lowest
Feed Speed
The lowest feed s peed f or your planer (16.2 fpm
& 20.7 fpm) can be obtained by replacing the
lower (gear shaf t) sprocket and the chain. See
Fig. 29. To change the sprocket and the chain
on your machine, proc eed as follows:
Figure 28
1. Disconnect machine from power source.
2. Remove the three hex cap screws and
washers (E, Fig. 28).
3. Remove the three sprockets (B, Fig. 28)
from the i nfeed roller, outfeed roller and t he
gear shaft at the same time.

Maintenance
Periodic or regular inspections are required to
ensure that t he machine i s in proper adj ustment,
that all screws are tight, that belts are in good
condition, that dust has not accumulated in the
electric al enclosures, and that there are no worn
or loose elect ri c al c onnec tions.
Lubrication
The bearings on the cutterhead are factory
lubricated and sealed for life – no lubrication
required.
The lubricant in the gearbox must be replaced
every 2,500 hours. Multi-purpose gearbox
lubricant will be sui table.
Buildup of sawdust and other debris can cause
your machine to plane inaccurately. Periodic
cleaning is not onl y r ecommended but mandat ory
for accurat e planing.
Close-fitting parts, such as the cutterhead slot
and gibs, should be cl eaned with a c lot h or brus h
and non-flammable solvent, and freed from
clinging foreign matter.
Remove resin and ot her acc um ulations f rom feed
rollers and table with a soft rag and nonflammabl e solven t.
Periodically check all the chains for proper
tension and adjust acc or dingly if required.
Tip: If a foreign object nicks the knives, i nstead of
throwing them away or trying to grind out the
deep nick, sim ply stagger t he knives i n the head,
moving one knife no more than 1/4" to the right
and another knif e no more than 1/4" to the l eft.
The nick should no l onger be noticeable.
The table shoul d be kept clean and free of rust.
Some users pref er a paste wax coating. A nother
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 sli ck and allows rust rings to be easil y
wiped from t he surface. Important al so is the fac t
that talcum powder will not stain wood or mar
finishes as wax pick up does.
To replace the gearbox lubr icant:
Remove the dr ain plug (A, Fig. 30), and filler cap
(B, Fig. 30). Drain dirty oil thoroughly.
Tighten the drain plug (A, Fig. 30).
Fill with cl ean lubricant through hole (B , Fi g.
30).
Tighten fill er cap ( B, Fig. 30).

Problem Possible Cause Solution
Chain jumping. Inadequate tension.
Sprockets misaligned.
Sprockets worn.
Machine will not
start/restart or
repeatedly trips
circuit breaker or
blo ws fuses.
No incoming power.
Overload automatic reset has
not reset.
Planer frequently trips.
Building circuit breaker trips
of fuse blows.
Adjust chai n tension.
Align sprockets.
Replace sprockets.
Verify unit is connected to power.
When planer overl oads on the ci r c uit breaker
built into th e motor s ta rte r , i t ta ke s time for the
machine to cool down befor e r estar t. Allow
unit to adequately cool before attempting
restart. If pr oblem persists, check amp setting
on the motor starter insi de the electrical box.
One cause of overl oading trips which are not
electric al in nature is too heavy a cut. If too
deep a cut is not the problem, t hen c hec k the
amp setting on the overload relays. Match the
full load amps on the motor as noted on the
motor plate. If amp setti ng is cor r ec t then there
is probably a loose elec trical lead. Check amp
setting on mot or start er .
Verify that planer is on a circuit of correct size.
If circuit siz e is corr ect, there is probably a
loose electri c al lead. Check amp setting on
motor starter.
Loose electri c al c onnec tions.
Motor starter failure.
Motor starter failure.
Motor failure.
Go through all the elec trical connections on
the planer including motor connections,
verifyi ng the ti ghtness of each. Look for any
signs of electri c al ar ci ng whic h is a sure
indicator of loose connections or circuit
overload.
Examine motor star ter for burned or failed
components. If dam age is found, replace
motor starter . If m otor st ar ter looks okay but is
still suspect, y ou have two options: have a
qualified elec trician test the motor starter for
function, or pur c hase a new starter and
establish if t hat was the problem on changeout.
If you have access to a voltmeter, you can
separate a starter failure from a motor failure
by first, verifying incoming voltage at 220 +/20 and second, checking the voltage between
starter and motor at 220 +/- 20.
If incoming voltage is incorrect, you have a
power supply problem .
If voltage between starter and motor is correct,
you have a motor problem .
If electrical motor is suspect, you have two
options: Hav e a qualified electrician test the
motor for function or remove the motor and
take it to a qualifi ed el ec tric motor repair shop
and have it tested.
