Safety
Oliver Machinery has made every attempt to provide a safe, reliable, easy-to-use piece of machinery.
Safety, however, is ultimately depending on the individual machine operator. Before operating this
machine, please become familiar with the following safety labels and guidelines.
DANGER
This indicate an imminent hazardous situation which, if not avoided, WILL cause
death or serious injury.
WARNING This means if the warning is not taken seriously, it CAN cause death or serious injury.
CAUTION This means if the precaution is not taken, it MAY cause minor or moderate injury.
IMPORTANT This is a tip about proper operation of the machine to avoid machine damage.
General Safety Guidelines
1. FAMILIARIZE yourself with all safety instructions found in this manual. Know the limitations and
hazards associated with this machine. Do not operate / service this machine until you are properly
trained.
2. ELECTRICAL GROUNDING, when done properly, reduce the risk of electrocution, shocks and fire.
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 a plug are used, make certain that the grounding
plug connects to a suitable ground. Follow the grounding procedure indicated in the electrical code
of your area.
3. DISCONNECT the machine from power before performing any service, maintenance, adjustments or
when changing cutters. A machine under repair should be RED TAGGED to show it should not be used
until the maintenance is complete.
4. EYE PROTECTION: Always wear an approved safety face shield, goggles, or glasses that complies with
ANSI Z87.1 and CSA Z94.3 standards. Common eyeglasses are not safety glasses, and may not provide
adequate protection.
5. EAR PROTECTION: Use hearing protective devices where the noise exceeds the level of exposure
allowed in Section 1910.95 of the OSHA Regulations. When in doubt, use it.
6. OTHER PERSONAL PROTECTION: Before operation, remove tie, rings, watch and other jewelry. Roll
up sleeves above elbows. Remove all loose outer clothing and confine long hair. Protective type
footwear should be used. Do not wear gloves unless it is instructed to perform particular step(s) in
the manual.
7. GUARDS: Keep machine guards in place for all applicable operations. If any guards are removed for
maintenance, DO NOT OPERATE machine until all guards are reinstalled. Check clearance between
the guards and the cutter before starting the machine.
8. WORKPLACE SAFETY: Keep the floor around the machine clean. Scrap material, saw dust, oil and other
liquids increase the risk of tripping or slipping. Be sure to clean up the table before starting the

10047VS Shaper OLIVERMACHINERY.NET 11 |Page
machine. Make certain 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.
9. ACCESS CONTROL should be enforced so only trained personnel can access the work area and operate
the machine. Use childproof power switch when applicable.
10. STAY ALERT at all times. Do not operate this machine while under the influence of drugs/alcohol, or
when not feeling well.
11. NEVER STAND ON MACHINE. This prevents injuries from tipping related accidents and accidental
contacts to cutters.
12. REPLACEMENT PARTS: Use only genuine Oliver Machinery replacement parts and accessories
recommended for this machine. Generic parts made by other manufacturers may create a safety
hazard, and WILL void the factory warranty and other guarantees.
13. PROPER USE: Do not use this machine for other than its intended use. If used for other purposes,
Oliver Machinery disclaims any real or implied warranty and holds itself harmless for any injury or
damage which may result from that use.

Safety Guidelines Specific to Shaper
Before Work Begin:
1. INSPECT CUTTER: Make sure cutters are sharp, clean, balanced and free from damages. Forcing dull
cutters to work invites accidents and impacts finish quality.
2. CUTTER POSITIONING: Whenever possible, position the cutter below the workpiece and make blind
cuts with hold-downs. Doing so reduce operator’s exposure to the cutter.
3. SECURE SPINDLE AND CUTTER: Make sure the spindle and the draw bar are tightened on the arbor.
4. KEYED COLLAR:Never operate the shaper without the keyed collar located
immediately under the spindle washer. Key collar prevents the cutter from coming
loose when the spindle rotates. Do not substitute any other type of washer/spacer in
place of the keyed collar.
5. CUTTER CLEARANCE: Adjust fence plates and guard, and use correctly sized table inserts to create
practically minimal cutter clearance. Never start shaper with workpiece touching the cutter.
6. CHECK SPINDLE SPEED AND SPINDLE-FEED DIRECTION:Always start this shaper at the lowest speed,
and never set rotation speed above the rated RPM of the cutter. Always feed stock against cutter
rotation direction to maintain better control of stock.
7. CHECK STOCK LENGTH: Never shape stock less than 12 inches in length without special fixtures. When
practical, shape longer stock and cut to size.
8. SHAPE ONLY QUALITY WOOD: This machine is designed for wood products only. Do not shape any
material other than wood. Do not attempt to shape workpiece with loose knots or with any other
foreign material. Do not attempt to shape twisted, warped, bowed stock. Use a jointer to flatten stock
prior to shaping.
9. COLLARS: When shaping with collars, the collar must have sufficient bearing surface. The work must
also be fairly heavy in proportion to the cut being made. Do not use short, lightweight stock when
shaping against collars.

10047VS Shaper OLIVERMACHINERY.NET 13 |Page
When Shaping:
1. 6-INCH RULE: To avoid accidental cutter
contact, never allow your hands to come
closer than 6 inches to the cutters. Use push
block, jigs, and hold-downs to safely feed the
workpiece while cutting.
2. NO CLIMB CUT: To prevent kickback, feed
stock opposite to the direction of the cutter
rotation. Never back stock out of the cutter
once the cut has been started. Instead, pull
the stock straight back away from cutter and
begin the cut again.
3. SHAPING SHORT EDGE:When shaping
workpiece with an edge shorter than 6”, use
miter gauge and hold down fixtures for
feeding.
WARNING
When using miter gauge, do not feed
workpiece against the fence. If the fence
is not perfectly parallel to the miter slot,
workpiece can bind and kickback may
occur.
4. FREEHAND SHAPING is for advanced users
only. Always use a starting pin or pivot board
when starting a cut. Never start shaping at a
corner.
5. MAKE LIGHT PASSES: Never force the cutter
to remove too much material in one pass.
Doing so increase the risk of kickback and
impact finish quality. Make several light
passes when applicable.
6. KEEP HANDS SAFE: Do not clear dust and
debris with hands; use a brush or
compressed air instead.
After Operation
1. STOP THE MACHINE when operator leaves the machine for any reason.
2. WAIT until the cutter comes to a complete stop.
3. CLEAN UP before departure.

When all items are ready for setting up the machine, gently remove the machine from the pallet. Lift the
shaper with its table. If using a forklift or any metal lifting devices, ensure the table is protected by
paddings. Gently lower shaper on the floor to prevent damages to the casters.

18 | Page Oliver Machinery 10047VS Shaper
Cleaning
To prevent rusting, the cast iron tabletop of this shaper
is covered with rust protectant and plastic film.
Remove both fence assembly lock knob to remove the
fence assembly. Then pull out the plastic film and wipe
off rust protectant with paper towels.
Once all rust protectant is removed, routinely coat the
table top with rust preventive such as Boeshield® T-9
or paste wax. Do not use rust preventives that contains
silicon, which is known to interfere with certain
finishes and glues.
Dust Collection
Shaper can generate a lot of wood shavings and dust.
Connect this machine to a dust collection system.
Minimum CFM requirement for this shaper is 800 CFM
at the dust port, which means your dust collection
system should have a rating greater than 800 CFM, as
air friction and leakage reduce effective CFM at the
dust port.
IMPORTANT
Running this shaper without dust collection system, or using a dust collection
system with inadequate suction, will cause dust and shavings to accumulate
inside the cabinet. This can damage the machine and cause other hazardous
situations. Check your dust collection system regularly to make sure it is not
jammed or filled up.
Moving / Leveling Machine
This shaper is equipped with casters so it can be moved easily. To keep the shaper in place, tighten the
