WARNING

Read this manual completely and observe all warning labels on the machine. Oliver Machinery has made
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.

• 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.

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.

4

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 Oliver Machinery factory authorized replacement parts and accessories; otherwise
the warranty and guarantee is null and void.

15. Do not use this Oliver planer for other than its intended use. If used for other purposes, Oliver
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, Figure 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, Figure 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, Figure 7) and move the
table rollers up, or down by raising, or lowering
the handle (D, Figure 7). When you reach the
desired position tighten the handle.

The rollers are usually set higher when planing
rough stock. When planing 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, Figure 8) until it
clicks into place. Change feed speed only

while the feed system is RUNNING!

Table Stop

The socket head cap screws (F, Figure 8) act as
a stop and prevent you from running the table
into the cutting and feeding assembly.

Opening Hood

Turn the locks (G, Figure 8) to open the hood.
The hood will open automatically. Use the
handle (H, Figure, 8) to shut the hood.

Setting / Changing Knives

WARNING!

Knives are extremely sharp. Be very careful

when handling knives. Failure to comply

may cause serious injury!

The Oliver 25” planer was designed to accept
25-1/8” x 1” x 1/8”) knives. Installing straight
knives accurately is an important step to achieve
a smooth finish. End to end, and knife to knife
adjustment must be accurate within .001". Use
a dial indicator if available to check results and
fine tune. Remove and replace the knife in one
slot before changing the next knife. Any knife
sharpening, or replacement should be done to
all four knives at the same time.

1. Disconnect machine from power source.

2. Open the hood, loosen ten locking bolts (A,
Figure 9) on the clamping block and remove
the knife. Remove and clean the clamping
block, and springs (B, Figure 10). Also
clean cutterhead knife slot before re­installing the sharpened, or new knife.

3. Re-install the springs, knife and clamping

block, and just snug the ten locking bolts (A,
Figure 9). Note: You should still be able to
raise and lower the knife.

4. Notice that the knife does not rest at the
bottom of the knife slot. Instead, the knife
rests on three jack screws (C, Figure 9), and
two springs. These jack screws are used to
support and raise the knife.

5. Place the knife setting gauge (D, Figure 11)
on to the cutterhead as shown in Figure 11.
Use the jackscrew to raise the knife so that
the point just touches the raised portion of
the gauge.

6. Once knife is set to the proper height,
tighten two center locking bolts and, work
your way towards the ends until all bolts are
tight.

7. Re-check knife with the knife setting gauge
after tightening all of the locking bolts.

8. Repeat for the remaining three knives.

Setup of Feed Rollers, Chipbreaker 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 in-feed roller,
chipbreaker, pressure bar and outfeed rollers.

Make a hardwood block to the specifications in
drawing Figure 13. You can use this wood
gauge along with 0.02” feeler gauge to set the
planer up as shown in Figure 12.

Figure 12 shows setup for general planing
applications. Depending on the stock and
cutterhead you may find that a different setup
may work better for your particular planing
operation.
