WARNING
Read this manual completely and observe all warning labels on the machine.
Every attempt to provide a safe, reliable, easy-to-use piece of machinery. Safety, however, is
ultimately the responsibility of the individual machine operator. As with any piece of machinery, the
operator must exercise caution, patience, and common sense to safely run the machine. Before
operating this product, become familiar with the safety rules in the following sections.
Safty Rule
Always keep guards and covers in place and in proper operating condition.
1. If you are not properly trained in the use of a planer do not use until the proper training has
been obtained.
2. Read, understand and follow the safety instructions found in this manual. Know the limitations
and hazards associated with this machine.
3. 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.
4. Wear an approved safety shield, goggles, or glasses to protect eyes. Common eyeglasses are
only impact-resistant, they are not safety glasses.
5. 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.
6. Keep the machine guards and covers in place for every operation. If any guards and covers
are removed for maintenance, DO NOT OPERATE the machine until the guards and covers
are reinstalled.
7. 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 the planer. Make certain the work area is well lighted and that
a proper exhaust system is used to minimize dust. Use anti-skid floor strips on the floor area
where the operator
normally stands and mark off machine work area. Provide adequate work space around the
machine.
8. Maintain a balanced stance and keep your body under control at all times.
9. Before turning on machine, remove all extra equipment such as keys, wrenches, scraps, and
cleaning rags away from the machine.
10. 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.

2
11. Before performing any service, maintenance, adjustments or when changing knives disconnect the
machine from power source. A machine under repair should be RED TAGGED to show it should
not be used until the maintenance is complete.
12. Do not plane boards with loose knots, nails or any foreign material in the workpiece. Irregular,
or warped stock should be jointed first on one side before planing a parallel surface.
13. 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 their departure. In addition, if the operation is
complete, they should clean the planer and the work area. NEVER clean the planer with power
"on" and never use hands to clear sawdust and debris; use a brush or air hose.
14. Use only genuine Machinery factory authorized replacement parts and accessories; otherwise the
warranty and guarantee is null and void.
15. Do not use this planer for other than its intended use. If used for other purposes, disclaims any
real or implied warranty and holds itself harmless for any injury or damage which may result from
that use.
16. Do not operate this machine while under the influence of drugs, alcohol, or any medication.
17. This machine is deigned for planing wood products only. Do not use to plane any kind of
substance other then wood.
18. Never start the planer while a workpiece is in contact with the cutterhead or knives.
19. Always feed workpiece against the rotation of the cutterhead.
20. 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:
CAUTION: (This means that if precautions are not heeded, it may result in minor or moderate
injury and/or possible machine damage)
WARNING: (This means that if precautions are not heeded, it could result in serious injury or
possibly even death).

Raising and Lowering Table
Turn the handwheel A (Fig. 7) clockwise to
raise the table. One revolution equals 1/32”
or 0.03”.
Note: The handwheel is spring loaded.
Push in on the handwheel and rotate
until the pins engage the detents.
Adjusting Thickness Scale
1. Run a board through the planer and
measure the thickness of the planed
board with a pair of calipers.
2. Adjust the pointer B (Fig. 7) by loosening
the screw that holds it in place.
Note: This measurement should be the
same as digital readout.
Table Roller Adjustment
Loosen the handle C and move the table
rollers up, or down by raising, or lowering
the handle D. When you reach the desired
position tighten the handle (Fin. 7).
The rollers are usually set higher when
planning rough stock. When planning smooth
stock the table rollers should be set slightly
above, or flush with the table.
Changing Feed Rate
The planer has three selectable feed speeds
that feed stock at 20, 25 and 30 feet per
minute. To adjust speed, turn lever E (Fig. 8)
until it clicks into place. Change feed speed
only while the feed system is RUNNING!
Table Stop
The socket head cap screws F (Fig. 8) act as a stop
and prevent you from running the table into the
cutting and feeding assembly.
Opening Hood
Turn the locks G to open the hood. The hood will
open automatically. Use the handle H to shut
the hood (Fig. 8).

ShearTec II CUTTERHEAD
Knife inserts are dangerously
sharp. Use extreme caution when inspecting,
removing, or replacing knife inserts.
The knife inserts on the 25”Planer are four-sided.
When dull, simply remove each insert, rotate it 90°
for a fresh edge, and re-install it. No further
adjustment is necessary. Use the two provided
torx wrench to remove the knife insert screw.
Use one of the torx wrenches to help hold the
cutterhead in Position, and the other to remove the
screw. See Fig. 9. 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.
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 jointer!
Make sure all knife insert screws are tightened securely.
Loose inserts can be propelled at high speed from a
rotating cutterhead, causing injury.
Warning: Disconnect machine from power source.

Setup of Feed Rollers, Chip Breaker and
Pressure Bar
WARNING!
Disconnect machine from the power source
before performing any adjustments or
maintenance. Failure to comply may cause
serious injury!
The planer comes set up from the factory and
shouldn’t need any adjustment.
If you find adjustment is necessary, follow
the below listed sections for setting the
infeed roller, chip breaker, pressure bar
and outfeed rollers.
Make a hardwood block to the
specifications in drawing Fig.13. You can
use this wood gauge along with 0.02” feeler
gauge to set the planer up as shown in
Fig. 12.
Setup for planning applications. Depending
on the stock and cutterhead you may find
that a different setup may work better for
your particular planning operation.

Helical Cutterhead
WARNING!
Knives are extremely sharp. Be very careful
when handling knives. Failure to comply
may cause serious injury!
The helical cutterhead is set-up with the same
relationship to the in-feed roller, chipbreaker,
pressure bar and outfeed rollers as the straight knife
cutterhead. The planer comes set up from the factory
and shouldn’t need any adjustment.
If you find adjustment is necessary, follow
the steps on pages 10-11 for setting the in-
feed roller, chipbreaker, pressure bar and
outfeed rollers in relation to the helical
cutterhead.
When it is time to rotate the carbide knives
ALL knives must be rotated at the same time.
This is the same when replacing carbide
knives ALL knives must be replaced at the
same time. Mark the knives with a marker
so you know which knives have been
rotated. You can rotate the knives three
times before replacing.Use the provided
tork wrench to rotate, or remove knives.
V-Belt Adjustment
Three V-belts A,Figure 21) drive the
cutterhead.The single V-belt (B, Figure 21)
drives the in-feed and out-feed rollers.
Belt tension has been set at the factory. If
the belts have stretched and need
adjustment.
1. Disconnect machine from power source.
2. Open lower rear, and lower left-hand side
panels. Loosen and tighten four
adjustment nuts (C, Figure 21) to move
motor plate up, or down to increase, or
decrease belt tension.Tighten nuts
against motor plate after adjustment is
made.
3. Belts are tensioned properly when
moderate finger pressure can deflect the
v-belts about a 1/4"-1/2” midway
between the pulleys.

13
Adjusting Table Gibs
Adjust gibs (D, Figure 22) by loosening the
hex nuts (E, Figure 22), and turning gib
screws (F, Figure 22) so that the ways
(G, Figure 22) are lightly contacted.
You should be able to get a 0.005” feeler
gauge in between the gib and way.
Adjusting Table Rollers
The table rollers come pre-set from the
factory and shouldn’t need any adjustment.
If you find adjustment is necessary, follow
the below listed steps.
1. Lay a straight edge (A, Figure 23) on
the table across the roller (B, Figure 23).
2. Raise the rollers until it contacts the
straight edge and lock the handle. The
pointer should be set at “0”. If not
adjust the pointer to read zero. Note:
Spin the roller by hand to know when
roller makes contact with the straight
edge.
3. Move straight edge to the opposite side
of bed roller and check to see that the
roller just contacts straight edge. If not
loosen the hex nut (C, Figure 24) and
turn the hex cap bolt (D, Figure 24) to
raise or lower the bed roller until it just
contacts the straight edge.

14
Maintenance
WARNING!
Disconnect the machine from power source
before proceeding with any maintenance,
lubrication or assembly! Failure to comply
may cause serious injury!
Periodic, or regular inspections are
required to ensure that the machine is in
proper adjustment, and that all hardware is
tight.
Clean out-feed rollers and table with a non-
flammable solvent to remove pitch, gum
and other unwanted build-up.
Periodically clean the inside of the machine
for dust control.
Keep pulleys and belts free from dirt, dust,
oil and grease. Replace worn V-belts as
needed.
There are three limit switches on the planer,
one that triggers if the hood is open, and a
raising and a lowering limit switch to
prevent the table from automatically
traveling too far. Keep these clean and
blown out with an air hose.
Lubrication
Add a few drops of medium weight oil to
the six oil cups (A, Figure 25) weekly.
Lubricate the two table elevation screws (B,
Figure 26) as needed. Raise the table and
remove the two screws holding the top of
the accordion cover (C, Figure 26) in place.
Pull the cover down and lightly grease the
elevating screws, see Figure 26.
Use an oiled cloth to wipe the ways (D, Figure 26)
weekly.
Lubricate the chain system with an oiled cloth as
needed.
The gear box oil should be changed once a year.
Remove the drain plug (E, Figure 27) to drain the oil.
Refill the gear box with 60-90 weight gear oil through
the fill hole (F, Figure 27) until the sight glass reads
full. The sight glass (G, Figure 27) should be
checked periodically and oil added as necessary.

15
Halted Feeding
If the in-feed roll takes stock away from you while feeding, then feeding stops before
contacting the knives, the chipbreaker is probably too low. Or the in-feed roller is not set low
enough, or does not have enough pressure. In a similar situation, the in-feed roll takes the
stock, the chipbreakers lift, and stops as you hear the knives contact the material. In this
case the pressure bar is too low. Follow the steps on pages 12-14 for setting the in-feed
roller, chipbreaker, pressure bar and outfeed rollers in relation to the cutterhead.
