SAFETY INSTRUCTIONS
For Your Safety Read Instruction Manual Before Operating Jointer
As with all machines, there is a certain amount of hazard involved with the use of this jointer. 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.
Wear eye protection.
Never make jointing , planning, or rabbeting cut deeper than 1/8 in.
Always use hold-down/push blocks for jointing material narrower than 3 inches, or planning material
thinner than 3inches.
Never perform jointing. Planning, or rabbeting cuts on pieces shorter than 8 inches (203 mm) in
length.
Keep guards in place and in working order.
Remove adjusting keys and wrenches. Form habit of checking to see that keys and adjusting
wrenches are removed from tool before turning it on .
Keep work area clean. Cluttered areas and benches invite accidents.
Don’t use in dangerous environment. Don’t use power tools in damp or wet locations, or expose them
to rain. Keep work area well lighted.
Keep children away. All visitors should be kept safe distance from work area.
Make workshop kid proof with padlocks, master switches, or by removing starter keys.
Don’t force tool. It will do the job better and safer at the rate for which it was designed.
Use right tool. Don’t force tool or attachment to do a job for which it was not designed.
Use proper extension cord. Make sure your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage resulting in loss of power and overheating Table
(see Figure 9) shows the correct size to use depending on cord length and nameplate ampere rating.
If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair
covering to contain long hair.
Always use safety glasses. Also use face or dust mask if cutting operation is dusty. Everyday
eyeglasses only have impact resistant lenses, they are NOT safety glasses.
Secure work. Use clamps or a vise to hold work when practical. It’s safer than using your hand and it
frees both hands to operate tool.
Don’t overreach. Keep proper footing and balance at all times.

3
Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.
Disconnect tools before servicing; when changing accessories, such as blades, bits, cutters, and the
like.
Reduce the risk of unintentional starting. Make sure switch is in off position before plugging in.
Use recommended accessories. Consult the owner’s manual for recommended accessories. The use
of improper accessories may cause risk of injury to persons.
Never stand on tool. Serious injury could occur if the tool is tipped or if the cutting tool is
unintentionally contacted.
Check damaged parts. Before further use of the tools, a guard or other part that is damaged should
be carefully checked to determine that it will operate properly and perform its intended function –
check for alignment of moving parts, binding of moving parts, breakage of parts, mounting , and any
other conditions that may affect its operation. A guard or other part that is damaged should be
properly repaired or replaced.
Direction of feed. Feed work into a blade or cutter against the direction of rotation of the blade or
cutter only.
Never leave tool running unattended. Turn power off. Don’t leave tool until it comes to a complete stop.
Do not perform jointing operation on material shorter than 10 in , narrower than 3/4 in, or less than 1/4
in thick.
Maintain the proper relationships of infeed and outfeed table surfaces and cutter head knife path.
Support the work piece adequately at all times during operation; maintain control of the work at all
times.
Do not back the work toword the infeed table.
Do not attempt to perform an abnormal or a little-used operation without study and the use of adequate
hold-down/push blocks, jigs, fixtures, stops and the like.

4
Hand safety. It is good practice to move the hands
in an alternate motion from back to front as the
work continues through the cut. Never pass the
hands directly over the cutter knife. As one hand
approaches the knives remove it from the stock in
an arc motion and place it back on the stock in a
position beyond the cutterknife.
Three inch rule. When working a piece of wood on
the jointer, follow the 3 inch radius rule. The hands
must never be closer than 3 inches to the cutter
head.
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:
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).

Uncrating the Machine
Uncrate the machine and inspect the unit for
signs of shipping damage. If damage is found,
contact your dealer immediately. Unbolt the
machine from the pallet. Retain all
packaging materials in case it becomes
necessary to ship the machine to another site.
Moving the Machine into Place
Do not lift the jointer by the tables from the
pallet to the shop position. This may change
coplanar alignment and will need to be
corrected before use. See page 13 for
coplanar adjustments.
To move the machine, use the supplied 3/4”
lifting bars by placing them through the stand
and securing with properly rated straps on
each side.
WARNING: The equipment used to lift this
machine must have a rated capacity at or
above the weight of the jointer. Failure to
comply may cause serious damage and injury.
Machine Preparation and Setup
The jointer must be positioned on a smooth,
level surface. The area must be well lit and
have plenty of room to maneuver with large
pieces of wood.
Level the jointer front to back and side to side
using a level placed on the table. Use shims
under the corners, if necessary, but make sure
the jointer is stable before being placed into
service.
Clean all rust protected surfaces with a
commercial solvent. Do not use acetone,
gasoline, lacquer thinner or any type of
flammable solvent, or a cleaner that may
damage paint. Cover cleaned surfaces with
WD-40 or a 20W machine oil.
Dust Collection
The 6” dust collection port (A, Fig. 1) is located
below the outfeed table. Typically flex hose is
used to run from this point to a central trunk
line.
Note: Do not operate the jointer without
dust collection.

Electrical Connections
Depending on how this jointer was ordered it could be
made to operate at 220V single phase or 220V/440V
three phase. Be sure to confirm the correct operating
rating before connecting to power.
The jointer is supplied with a power cord, but no plug.
It may be hardwired to the service in accordance with
local electrical code. If a plug is used it must be
properly rated for the motor and match the outlet used.
Never use an adapter between plug and outlet and
always ground the machine.
To convert from 220V three phase to 440V three
phase new parts are required. Contact Oliver
Machinery for details.
With three phase power make sure the cutter head
rotation is in the proper direction.
All wiring and electrical connection must be done by a
qualified electrician and meet local electrical codes.

Control Switch
The control switch comes mounted to the infeed table
as shown Fig. 1
The control switch features an on and an off switch.
The off switch features a lock that must be twisted
clockwise to reset before the machine can be started.
This machine features magnetic motor controls. In
the event of power loss, the machine will not start
when power is restored until the on switch is pressed.
WARNING: Ensure that your workplace is
inaccessible to children by closing and locking all
entrances when you are away. NEVER allow
untrained visitors in workplace when assembling ,
adjusting or operating equipment.
Cutterhead Guard Installing & Removal
1. Disconnect jointer from power source.
2. Turn knob (A) counterclockwise to create tension
on spring, and hold it there Fig 3.
3. Insert guard post (B) down through hole in front of
ledge.
4. Slightly turn set (A), if necessary, until the guard
seats itself, and the spring engages the slot at the
end of the guard post.
5. Check the guard for proper tension. If guard does
not spring back into place when pulled back from
cutterhead, remove guard and adjust spring
tension by repeating steps 1-3 until correct tension
is achieved. NEVER run the jointer without the
guard.

Helical Cutterhead
Knife inserts are dangerously
sharp. Use extreme caution when inspecting,
removing, or replacing knife inserts.
The knife inserts on the Jointer 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. A. 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.
