• Do not operate the planer when tired, distracted or under
the eects of drugs, alcohol or any medication that impairs
reexes or alertness.
• Ensure your working area is well lit and free of debris.
• Keep children and visitors at a safe distance when the
planer is in operation. Do not permit them to operate
the planer.
• Prevent unauthorized or unsupervised use by child
proofing and tamper proofing your shop and all
machinery with locks, master electrical switches and
switch keys.
• Stay alert! Give your work your undivided attention. Even a
momentary distraction can lead to serious injury.
• Fine particulate dust is a carcinogen that can be hazardous
to health. Work in a well-ventilated area and whenever
possible use a dust collector. Protect your face, eyes,
ears, lungs and body with suitable personal protective
equipment.
• Do not wear loose clothing, gloves, bracelets, necklaces or
other jewelry while the planer is in operation.
• Remove adjusting wrenches, tools and other clutter from
the machine and the table surface before operating the
machine.
• Keep hands well away from the cutterhead and all moving
parts. Feed stock with a push stick, and use a brush, not
your hands, to clear away chips and dust.
• Make sure carbide inserts are correctly and securely
installed in the cutterhead.
• Inspect stock and remove all foreign objects before
planing. Make sure that stock is clean and free of dirt,
nails, staples, rocks or any other foreign objects that could
damage the carbide inserts. Only process natural solid
wood boards. Never plane MDF, particle board, plywood,
laminates or any synthetic materials.
• Do not force material. e planer performs best when
working at the manufacturer's intended rate.
• To minimize the risk of injury from kickback, which
occurs when the workpiece is ejected by the force of the
cutterhead, use proper feeding technique and stand to one
side, out of the path of a potential kickback.
• Avoid working from awkward or o balance positions. Do
not overreach and keep both feet on oor.
• Select appropriate feed speed for the stock being planed:
Use high speed for so wood and slow for hardwood.
• Place stock rmly against the table and use in-feed and
out-feed support if stock is too long.
• Keep guards in place and in working order. If a guard must
be removed for maintenance or cleaning, properly re-
attach it before using the planer again.
• Never leave the planer unattended while it is running or
with the power on.
• Never stand on machinery. Serious injury could result
if the planer is tipped over or if the belt or disc is
unintentionally contacted.
• Always disconnect the machine from the power source
before changing inserts; performing maintenance, cleaning
or servicing; or leaving the machine unattended.
• Ensure the switch is in the OFF position before plugging in
the power cord.
• Make sure the machine is properly grounded. If equipped

CONNECTIN TO A POWER SOURCE
Once you have assembled the planer, plug the power cord into an appropriate
outlet. Refer to the Electrical Requirements section and follow all requirements and
grounding instructions.
MANETIC SAFETY SWITCH
is machine is equipped with a magnetic safety switch designed to protect the user
from unintentional startup. e switch assembly features a green START BUTTON
(A)and a red spring-loaded STOP BUTTON (B). Once the STOP BUTTON has been
pressed, restart the planer by turning the inner part of the button to the right. is
releases the stop button. See Figure 7.
OVERLOAD PROTECTION
e magnetic safety switch is equipped with an overload protection feature. In the
event of a spike in line voltage or amperage draw, the internal overload protector will
automatically trip and cut o power to the motor.
Electrical overloads can be caused by the following:
• Overworking the motor by forcing thick, dense material through the planer. is
causes an increase in power consumption and a spike in amperage draw.
• Using an electrical extension cord that is too long or not the correct gauge,
which can also cause an increase in amperage draw. If you are unsure about
choosing an appropriate power cord, contact a qualied electrician.
• Operating the machine on a circuit that is close to its amperage draw capacity.
Make sure the circuit is capable of handling the amperage draw from this
machine as well as any other electrical devices operating on the same circuit. If
you are unsure, consult a qualied electrician.
To reset the overload protection switch aer it has been tripped, follow these steps:
1. Unplug the machine.
2. Open the motor door in the back of the machine and remove electrical box cover.
See Figure 8.
3. Press the BUTTON (C)to reset the overload protection. See Figure 9.
4. Before starting the machine, secure the cover box and close the motor door.

WARNIN!
Before making adjustments, make sure the power cord is unplugged and the switch is in the OFF
position. Do not plug in or turn on the machine until you have fully assembled the machine.
ADJUSTIN TABLE ROLLER HEIHT
e planer features two adjustable TABLE ROLLERS (A)
that help reduce friction when feeding stock. You can set
the height of the rollers to suit personal preference as well
as the type of stock. See Figure 10.
As a general rule when planing rough stock, set the rollers
higher. When planing smooth stock, set the rollers lower.
To adjust the height of the table rollers follow these steps:
1. Loosen the LOCK LEVER (B)and turn the
ADJUSTMENT LEVER (C)up or down as needed.
2. Tighten the LOCK LEVER (B)to secure the rollers at the
desired height.
IMMOBILIZIN THE PLANER
During operation, vibration can cause the planer to move,
particularly when installed on an uneven surface.
Use the ANCHOR BOLTS (D)and pads to immobilize the
planer. Either lower the bolts against the pads on the oor
to act as points of contact with the oor, or for permanent
installation, drill into the oor and bolt the machine in
place. See Figure 11 for anchor bolt location.

OPERATIN INSTRUCTIONS
MAGNUM INDUSTRIAL 20" HEAVYDUTY PLANER
MI-31550 / MI-31552 / MI-31553
BASIC PRINCIPLES OF PLANIN
is planer is designed to remove material from the top face of a board in order to bring the board (or a series of boards)
down to a specic desired shape or prole and thickness. To obtain uniform results across the length of a board, the stock
being planed must have one face that has already been machined perfectly at (usually on a jointer) and the stock should
be fed with this at face against the table.
SELECTIN BOARDS
is planer is intended for use with solid woods or MDF only, and should not be used to plane or mould any other materials.
e workpiece should always be fed through the machine in the general direction of the grain in the wood. Before being fed
through the planer all lumber should be inspected for debris and foreign objects such as staples or nails.
Foreign objects embedded in your workpiece can be ejected from the machine at high speed, causing serious injury or
damaging cutter knives. Remove all foreign objects from the wood before planing it. Select lumber carefully and avoid
workpieces with loose or protruding knots. Also avoid workpieces that are twisted, severely deformed or warped.
Planing warped, twisted, damaged or fragile stock increases the risk of jamming or damaging the machine or cutters, as
well as increasing the risk of injury to the operator or bystanders from kickback. Kickback occurs when the workpiece is
forcefully or violently ejected from the machine.
WARNIN!
Respect the rated capacity of this machine. Ignoring these ratings and feeding non-compatible
stock into this planer can lead to serious injury to the user and/or bystanders and cause damage
to the workpiece and/or the machine. See Figure 12.

MI-31550 / MI-31552 / MI-31553
WARNIN!
Before making any adjustments, ensure the power switch is OFF and the power cord is unplugged
ADJUSTIN CUTTIN DEPTH
You can adjust the cutting depth by turning the HANDWHEEL
(A). e maximum cutting depth on full width planing is 1/8".
For both hard and so wood, the planer is more eective when
removing less material per pass and taking multiple passes.
To adjust the cutting depth, follow these steps:
1. Turn o the machine.
2. Position the board under the infeed roller and adjust the
position of the table with the handwheel so that the infeed
roller touches the board.
3. Remove the board and adjust the cutting depth using the
SCALE (B)by turning the handwheel clockwise.
ADJUSTIN FEED SPEED
e feed motor speed operates at 22 or 28 feet per minute.
You can adjust the feed speed with the FEED SPEED
ADJUSTMENT KNOB (C), which located on the right side
of the planer. Choose the appropriate feed speed for the
stock: use high speed for so wood and slow for hardwood.
Experiment with feed speeds to nd the right speed for each
workpiece.
To increase the feed speed, see Figure 14 and follow these
steps:
1. To increase the feed rate to 28 fpm, pull the knob out.
2. To decrease the feed rate to 22 fpm, push the knob C in
3. To set the gearbox to neutral, move the knob C to the
middle position.

PLANIN CHECKLIST
• Inspect the board and ensure it is suitable for planing.
• Wear appropriate workshop attire. Roll up long
sleeves, secure long hair and remove any jewellery,
watches, rings, bracelets or anything that could get
caught in moving parts.
• Wear eye, hearing and respiratory protection.
• Check that all components, including fasteners and
moving parts, are securely installed before starting
the planer.
• When planing multiple boards, collect them on a
nearby table within reach. To limit the potential for
injury in the event of a kickback, avoid stepping in
front of the planer to pick up the next workpiece.
WARNIN!
To avoid damaging to the gearbox, change
speeds only while the machine is running.
