1. Remove the crate from around the planer
and any fasteners secur ing t he pl aner to t he
skid.

2. Remove the side covers and place t he lifting
hooks into the slot s (Figure 1). Place straps
under them and l if t t he machi ne off the ski d.
The planer should be located on a sturdy
floor, pref erably concrete, in a dry area with
sufficient lighting. Leave enough space
around the machine for loading and
offloading stock and routine maintenance
work.

3. When the planer is situated, use the leveling
screws (Figur e 2) to lev el the mac hine.

4. Exposed metal areas of the planer have
been factory coated with a protectant. This
should be removed with a soft cloth and
kerosene. Do not use an abrasive pad. Do
not let solvent contact the plastic parts of
the machine, as it may damage t hem .

Figure 1

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.

The planer may be fitt ed with a 230 volt plug, or
may be “hard-wired” directly to your electrical
panel. If hard-wired to a panel, make sure a
disconnect i s available for the operator.

IMPORTANT: The 230 volt model of the
WP2412 planer is wired for 230 volt only; it is
not convertible to 460 volt.

1. Make sure the machine’s plug is
disconnected f rom the power source. If it is
hard-wired, m ake sure the fuses hav e been
removed or t he breakers hav e been tripped
in the circuit to which the saw will be
connected. Pl ace a warning placard on the
fuse holder or circuit breaker to prevent it
being turned on while the machine i s being
wired. Always follow proper Lock Out/Tag
Out procedures when perf orming any wiri ng
on this machine.

2. Make sure the voltage of the power source
corresponds to the v oltage of the pl aner as
recorded on the mot or pl ate.

3. Open the electrical enclosure on the left
side of the machi ne (Figure 3) by loosening
the screws and sliding the panel upward.

4. Connect the three phases to the terminals
marked L1, L2, L3 (Figur e 4) .

5. Connect the green neutral wire to terminal
“N”.

6. Connect the mac hine to power (or install t he
fuses or reset the breakers at the power
source).

7. Test the rotation of the cutterhead. Turn on
the main power switch (see Figure 5) and
then the main m otor switch (Figure 5) . The
pulley on the main mot or (on the side near
the electrical enclosure) should rotate
counterclockwise. If it rotates clockwise,
stop the machine with the red stop button
(Figure 5 ).

8. Disconnect machine from power source,
and exchange leads L1 and L2.

Figure 3

9. Reconnect power, and close the electrical
cover.

Dust Collection

It is strongly recommended this planer be
connected to a dust extraction system, via the 6”
(160mm) dust port at the rear of the planer. Your
dust collector should have at least 1500 CFM
capacity.

Adjustments

Controls

Figure 5 shows the control panel for the planer.

Starting procedure

NOTE: The planer will not start if the hood is
raised, or if the brake release light is on (see
below).

1. Turn Main Switch to position “I”. [NOTE: The
main switch has a lock-out hole, through
which a padlock or similar device can be
inserted, when the swit c h is in “O” position]

Figure 4

2. Push the Mai n M otor S tart butt on; t he mot or
will start in Star-Delta. After a few seconds
you will hear the motor switch over to full
speed operation. NOTE: The inverters (see
Figure 3) have been factory programmed
and their setti ngs should not be altered.

Figure 5

3. The Reset button (Figure 5) will light up if
the machine becomes overloaded. Press
this button to re- start the machine.

4. The Emergenc y Stop Butt on shuts down all
operations on the planer. An automatic
brake stops the m otor within 10 secon ds. A
similar stop but ton can be found at the back
of the machine. To restart the machine,
simply twist the stop button and allow it to
pop back up

5. To begin the feed motor and rotati on of the
feed roll ers, press the Potentiom eter button
on the dial. Rotate the dial to set the feed
speed. Speed ranges fr om 16 to 72 feet per
minute. The num bers on the dial are shown
as 1 to 11; the higher t he number , t he faster
the speed. To stop the feed mot or press the
Potentiom eter butt on again.

6. The Brake Release switch frees the
cutterhead so t hat it can be mov ed by hand
(e.g. when changing knives). When the
brake release is o n, the switch stays lit. As a
safety feature, the planer’s motor will not
start if t he brake release switch is l it. And if
the switch i s pushed during operat ions, the
motor will automatically stop. To restart the
planer, de-press the brake release switch;
the light will turn off.

7. To raise the table press the up-arrow
buttons; to l ower the table pr ess the down­arrow buttons. The single arrows raise the

Calibrating Digital Display

Before operating the planer, the digital display
should be checked for accuracy and c alibrated if
necessary. Use a scrap board.

1. Set the table to just under t he thickness of
your scrap board, u si ng the scale next to t he
table (Fi gure 6). Feed t he board thr ough the
planer to achiev e a planed si de.

2. Raise the table slightly until the adjoining
scale pointer is set evenly on a number.

3. Fli p the board over and f eed it through the
planer, then c arefully measure it s thickness
with calipers. Compare this with the digital
display.

4. If the display needs correcting, press and
hold “Function,” and press “Reset”. The
display will return to zero.

5. Press and hold “Function,” and press “Set”
until the di splay shows the thi ck ness of your

Belt Tension & Replacement

Note: Belts should be replaced as a matched set
of three.

1. Loosen the three bol ts (A, Fi gure 10) which
hold the motor support br ac k et to the frame.

2. Turn the hex nuts (B, Figure 10) on the
tension rod as needed.

3. When finished, tighten the three bolts (A,
Figure 10).

Drive Chain Replacement

The drive chains do not require tension
adjustment, since tension is always assured
by an idle chain tensi oner ( C, Fi gur e 11) .

To replace the main drive chain, pull the
tensioner (C, Figure 11) backward and
remove the c hain from around the sprockets.
When the new chain has been mounted,
always make sure the ten sioner is well plac ed
on the chain.

To replace the chain for the table raising
mechanism, pull the lever (D, Figure 12) to
the back and remove the chain. When the
new chain has been m ounted, pu sh the lev er
(D, Figure 12) bac k into posi tion.

Figure 10

Figure 11

Do not tu rn th e sprockets o n

the table raising screws with the chain
removed. Doing so will mi sali gn the t abl e.

Figure 12

13

Feed Rollers

The infeed and out feed rollers and chipbreaker
have been factory set. However, if spring
tension adjustment should ever be necessary,
use the appropriate adjustment assembly
located beneath the lip of the frame – one is
shown in Figure 13.

1. Loosen the nut and t urn the screw in or out.
When finished, tighten nut.

2. Perform the same adjustment at the
opposite end of the rol ler.

Table Rollers

The table roll ers can be raised or lowered with
the handle (Figure 14). A label is affixed near
the handle for ref er enc e.

Maintenance

Before any intervention on

the machine, di sconnect it from the electrical
supply by pulling out the plug or switching
off the main switch! Follow lockout/tagout
procedures. Failure to comply may cause
serious injury.

The anti-kickback fingers m ust hang down f reely
and operate independently by gravity. They
should be inspected frequently and cleaned
whenever necessary.

Figure 13

Figure 14

The table should be k ept clean and free of rust

Troubleshooting : Mechanical & Electrica l Problems

Trouble Probable Cause Remedy

Board thickness does
not match digital
display

Digital displ ay not calibrated properly. Foll ow calibration procedures.

Chain jumping

Machine will not
start/restart or
repeatedly t rips
circuit breaker or
blo ws fu ses.

Inadequate chain tension. Adjust chai n tension.
Sprockets mi sali gned. Align sprockets.
Sprockets worn. Replace sprockets.

No incoming power.

Overload aut omatic reset has not
reset.

Planer frequently trips.

Verify unit is connected to power, and
main switch is set to “I”.

When planer overl oads on the ci r c uit
breaker built into the motor starter, it
takes time for the machine to cool
down before restar t. Allow unit to
adequately cool bef ore attempting
restart. If pr oblem persists, check
amp setting on the mot or start er
inside the electrical enclosure.

One cause of overl oading trips which
are not electric al in nature is too
heavy a cut. The solution is to take a
lighter cut. If too deep a c ut is not t he
problem, then chec k the amp setting
on the overload rel ay . Match the full
load amps on the motor as noted on
the motor plate. If amp setting is
correct then ther e is probably a loose
electric al lead. Check amp setting on
motor starter.

Building circuit breaker trips or fuse
blows.

Loose electri c al c onnec tions.

Motor starter failure.

Verify that planer is on a circuit of
correct size. If circuit size is correct,
there is probabl y a loose el ectr ic al
lead. Check amp setting on motor
starter.

Go through all the electrical
connections on the planer including
motor connecti ons, verifying the
tightness of each. Look for any signs
of electrical ar ci ng whic h is a sure
indicator of loose connections or
circuit overload.

Examine motor star ter for burned or
failed component s. If damage is
found, replace motor starter. If motor
starter look s okay but is still suspect,
you have two options: Have a
qualified elec trician test the motor
starter for function, or purchase a new
starter and establish if that was the
problem on changeout . (continued)

16

Trouble Probable Cause Remedy

Machine will not
start/restart or
repeatedly t rips
circuit breaker or
blo ws fu ses.

Motor starter failure.

Motor failure.

Miswiring of the unit.

If you have access to a voltmeter, you
can separate a starter f ailure from a
motor fai lu re by fi r st, verify ing
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 start er and m otor is
incorrect, y ou hav e a starter pr oblem.
If voltage bet ween start er and m otor
is correct, you hav e a motor pr oblem .

If electri c mot or i s suspect, you have
two options: Have a qualified
electrician test the motor for function
or remove the motor and take it t o a
qualified elec tric motor repair shop
and have it tested.

Double check to confirm all electrical
connections are cor r ec t and properly
tight. The elect ri c al c onnec tions other
than the motor are pre- assembled
and tested at the factory. Therefore,
the motor connections should be
double checked as the highest
probability for error. If problems
persist, double c hec k the factory
wiring.

On/off switch failure.

If the on/off switch is suspect, you
have two options: Hav e a qualified
electrician test the switch for function,
or purchase a new on/off switc h and
establish if that was the pr oblem on
changeout.
