GROUNDING INSTRUCTIONS
1. In the event of an electrical malfunction or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric
cord having an equipment grounding conductor and a grounding plug. The plug must be plugged into
a grounding outlet. The plug must be plugged into a matching outlet that is properly installed and
grouded in accordance with all local coodes and ordinances.
2. Do not modify the plug provided.If it will not fit the outlet, have the proper outet installed by a
qualified electrician.
3. Improper connection of the equipment-grounding conductor can result in a risk of electric shock.
The conductor with insulation having an outer surface that is green with or without yellow stripes is
the equipment-grounding conductr. If repair or replacement of the electric cord or plug is
necessary,do not connect the equipment-grounding conductor to a live terminal.
4. Check with a qualified electrician or service personnel if the grounding instructions are not

MM3156A DRUM SANDER
５
completely understood or if in doubt as to whether the tool or outlet is properly grounded.
5. Use only 3-wire extension cords that have grouding plugs, and the receptacles must accept the
tool’s plug.
6. Have a damaged or worn cord repaired or replaced immediately by a qulified technician.
EXTENSION CORDS
When using a power tool at a considerable distace distance from a power source,use an extension
cord heavy enough to carry the curremt that the tool will draw. An undersized extension cord will
cause a drop in line coltage,resulting in a loss of power and ocerheating.
When working with the tool outdoors, use an extension cord that is designed for outdoors.
Before using an extension cord,inspect it for loose or exposed wires and cut or worn insulation
Also, do not use an extension cord on a take up reel. The electric current passing through the
extension cord will generate heat, and if the cord is wrapped around a reel, a heat buildup will result
that could melt the insulation, causing a fire and/or electric shock.
CAUTION: Keep the cord away from the sanding area and position the cord so that it
will not be caught on lumber, tools, or other objects during sanding.
INTRODUCTION TO DRUM SANDING
FUNCTION
Drum sanding, sometimes referred to as ”abrasive planting” is a repetitive process of
sanding both sides of wooden stock to a desired thickness and/or smoothness. When
this performed correctly, both face surfaces will be parallel to one another.
Do not confuse drum sanding with thickness planning! Drum sanding gradually
removes material in increments of 1/32” or less depending on sanding grit, stock
hardness, stock hardness, stock width, etc. Thickness planning,on the other hand, is for
quick, bulk material removal at rates up to 1/8” per pass with portable machines. If you
have used a thickness planer to smooth and dimension stock you will quickly learn to
work with your new drum sander and not against the machine.Be patient, let the drum
sander do the work,1/32”or less per pass for best results.
The most common mistake made with a drum sander is forcing it to remove too much
material too fast. Variables such as sandpaper grit, stock width, wood type, feed rate,
and moisture content all influence how much material can be removed in a single pass.

MM3156A DRUM SANDER

DRUM SANDING ADVANTAGES
One advantage of the wide drum sander is that you can work with material up to 32”
wide with this unit because of its open side design. Although you still abrasive sand with
the grain, you do not have to read the grain to prevent tear-out. This is especially
important with thin stock and material with convoluted or mixed grain directions, like bulr,
crotch, and tiger patterns.
Drum sanders exert much less pressure on stock than a thickness planer, giving you the
capability of working with very thin material. You have the ability to sand to veneer
thickness if desired, expanding your woodworking horizons. You can also sand smaller
lengh wood, odd-shaped pieces, and end-grain.
REMOVING LUMBER CUP
The ideal machine for removing cup from luber is a jointer. However, because of the
minimal pressure exerted by the drum sander, it is possible to remove cup, since the
lumber is not compressed flat on feed belt and table. Be patient, this process can take
quite a while deoending on cup depth. Feed the stock into the machine cup crown up
(edges resting on feed belt) and use a coarse grit abrasive. Repeat until the crown is flat.
With one face now flat, flip the board over and sand it flat. Do not be shocked by how
thin the board may become after all cup has been removed.
Board warp and twist will not be remedied by a drum sander, or a planer, for that matter.
Always inspect your lumber for warp and twist before drum sanding since it is prone tp
hanging-up in the machine, shorter length lumber in this condition is especially
troublesome.
PLAN YOUR WORK IN ADVANCE
Planning your drum sanding operations in advance will minimize setups, work time, and
frustration level. Group material to be sanded by thickness and grit requirements and
work through each required sanding grit starting with the thickest material through the
thinnest, then change over to next finer grit and begin the process again.
We suggest that you experiment with the varions sanding grits and wood species to
determine the results you can expect before ruining project material. With new set-ups,
always test with scrap lumber before sanding your project material.
WOOD SPECIES TO BE CAUTIOUS WITH
Highly resinous species will tend to quickly clog (load-up) abrasives and in many cases
abrasive loading cannot be removed with belt cleaning sticks.The most notorious
abrasive loaders are some common pine species. It is nearly impossible to clear the
abrasive of the pitch, sap sawdust combination.
Be aware of species that have toxic properties, such as members of the rosewoodfamily

(i.e.cocobola). Despite dust control, you may inhale small airborne particulate or suffer
allergic reactions through handing of stock. Wear a mask and gloves for extra protection.

However, due to stresses imposed on the unit during shipment, you may need to adjust
or align your unit or return it to perfect alignment. It is very important that the following
adjustments be performed as described.
WARNING: Never make any adjustments with the unit connected to the power source.
Failure to heed this warning can result in serious personal injury.
WARNING: Always secure tool to workbench or workstand to avoid tendency for tool
to tip over, slide, or walk on the supporting surface. Failure to secure tool can result in
serious personal injury.
SANDING DRUM DEFLECTION
Before beginning the sanding drum alignment procedures outlined in the following
section, ensure that minimal upward deflection of the sanding drum occurs when
sanding. The three primary causes of excessive sanding deflection are:
1. Excessive depth of cut. Decrease the depth of cut to minimize pressure on the
sanding drum assembly. Refer to the Introduction to Drum Sanding
section for hints regarding depth of cuts.
2. Loose Elevation Tension Screws. Refer to Step 1 in the Drum Alignment section
for hints regarding depth of cuts.
3. Loose Motor/Sanding Drum Assembly Mounting Bolts. (See Figure 6.) Check the
tightness of the four (4) bolts, 2 upper and 2 lower, and tighten as needed.
Figure 6
DRUM ALIGNMENT
WARNING: To prevent possible serious personal injury, always disconnect the wide
Drum Sander from the power source before serving the unit, aligning, or making any
adjustments.
1. Check the tightness of the Elevation Tension Adjustment Screws (Figure 7).
The tightness of these screws must be adjusted to allow smooth height

adjustments, while ensuring a tight enough fit to limit drum deflection. (If the
screws are too loose, the drum will deflect during use, causing an uneven
sanding surface. If the screws are too tight, sanding drum height adjustments
will be difficult.)
Figure 7
2. To adjust the Elevation Tension Adjustment Screws, loosen the lock nuts, securing
each screw in place. Loosen or tighten each screw, as required, in 1/4 turn increments to
attain the desired fit and smoothness. Retighten the lock nuts to secure the tension
screws in position.
3. Check the sanding drum to conveyor table alignment by first removing the abrasive
strip from the abrasive strip from the drum. The purpose of this adjustment is to achieve
equal distances at point A and point B which will ensure that the drum is parallel to the
feed table and provide uniform sanding. (See Figures 8.)

2. To tighten the tracking tension, the tracking screw is rotated clockwise while holding
its nut in place with a 7/16” open end wrench (not supplied).To loosen the tracking
tension, the tracking screw is rotated counterclockwise while the nut is held with the
wrench.
3. If the converyor feed belt is tracking towards the inboard (motor side) of the machine,
tighten (add tension) to the tracking adjustment screw on that side of the machine.
NOTE: Due to the width of the conveyor feed belt, tracking adjustments may not
become apparent immediately! Increase the speed of the conveyor feed belt to
hasten the effects of your adjustments. Make small measured corrections of

approximately 1/4 turn increments and evaluate the results. RE-adjust as
necessary until the proper tracking solution is found.
HELPFUL HINT
Tighten the side opposite the desired tracking direction. For example, tighten the
right side tracking adjustment to make the conveyor feed belt track left.
OPERATING INSTRUCTIONS
WARNING: Never put your fingers into port or under drum cover.
CAUTION: To avoid damage to your Durm Sander, adequate dust collection must be
must be used during sanding operations. A 2-1/2” port is included in the sanding drum
dust cover for connecting dust collection unit/hose to your Wide Drum Sander.
DRUM HEIGHT CONTROL
The height of the drum is raised by turning the height control knob (refer to Figure 2) in a
clockwise direction. To lower the drum, turn the height control knob in the
counter-clockise direction. The depth of the movement is approximately 1/64” per 1/4
turn in either direction. One complete turn is 1/16”. Depth settings can be measured
using the depth indicator scale located on the right side of the drum support frame.
NOTE: Depth settings used during surface sanding of stock are adjusted by
considering several variables.The hardness of the material, the width of the
material being surfaced, and the feed rate selected are all considered when
determing the amount of material to be removed on each pass. Never remove
more than 1/32”of material in one pass. The variable feed rate is set to prevent
burning and provide a smooth sanded surface on different types and widths of
materials. As a general rule,1/4 turn or 1/64” or less is recommended stock
removal for coarser grits and softer woods, while 1/8 of a turn or 1/128” may be
more desirable with harder woods and/or finer grits if abrasives. When selecting
the rate of feed for the material being surfaced, the wider the material, the slower
the feed rate to be set. Similary, the harder the wood, the slower the feed rate.
Some experimenting and practice will be required to become familiar with the sanding
performance of your Wide Drum Sander. While performing a surfacing operation with
your Wide Drum Sander closely parallels the wide surface preparation of a planer, a
planer is much more capable of making deeper passes due to its characteristic knives,

MM3156A DRUM SANDER
１８
while a Wide Drum Sander is limited to its abrasive material for stock removal.
SANDING
1. With power off, rest stock on the feed table and advance the stock to a point so that
you can adjust height of sanding drum to equal thickness of stock at its greatest
point.
2. Connect and turn on dust collection equipment.
3. Adjust feed rate to match sanding requirements and width of stock.
4. Turn on unit and rest stock on the feed conceyor table allowing the fee bekt to carry
the stock into and engage the sanding action of the drum. Support long stock as
necessary during the feed operation. Once the sanding operation feed allows,
reposition yourself to the outfeed side of the machine to accept, support, and control
the board as it exits the Wide Drum Sander.
NOTE: Do not apply upward or downward pressure when supporting and guiding stock
through the sander. To do so may induce snipe (sander drum dig-in) into the sanded
stock.
5. Reverse the feed direction of the stock on successive passes, while adjusting the
depth of cut using the height adjustment handle assembly (refer to Figure2). Several
variables affect the proper depth of cut selected. They are: abrasive grit choice, width
of stock, hardness of stock, feed rate and moisture content of stock.
INSTALLING NEW REPLACEMENT ABRASIVE STRIPS
WARNING: To prevent possible serious personal injury, always disconnect the Wide
Drum Sander from the power source before serving the unit or changing the abrasive
strips.
Abrasive strips are available from local dealer in precut strips which require no special
measuing or trimming before installation. The abrasive strips are tapered at the ends to
be wrapped radially around the drum to provide a continuous sanding surface. You may
cut your own strips from bulk stock using the included abrasive strip as a pattern for
cutting your new replacenent strip.
1. Make sure the power swotch is off and disconnect the power cord from the outlet.
2. Using either a precut strip or one which you have cut for use, you begin the abrasive
installation by inserting the tip of the tapered strip into the slot in the left side of the
drum while depressing the clip (Figure13). Approximately one inch of material should
be inserted into the slot to make the connection in the abrasive clip. Release clip
pressure once the inserted tapered end is securely loaded in the clip jaws.

MM3156A DRUM SANDER
１９
Abrasive Cutting Specification
Figure 13
3. Once the abrasive strip is secured in the left clip, stand in front of the unit and radially
wrap the abrasive material. Roll the drum away from you with your left hand while
holding tension on the abrasive strip with your right hand and guiding the material
onto the drum. Use this technique to warp the abrasive strip edge to edge radilly
around the drum. Make sure you do not overlap the material as you wrap the
abrasive (Figure 14).The material should be flush to slightly gapped, but not
overlapped, during the wrap.
Figure 14
4. When you have completely wrapped the drum, keep tension on the strip and insert
the remaining tapered end of the strip into the slot in the drum. Using your right hand,
raise the tensioner clip completely to open the jaws. Insert the tapered end of the
abrasive strip (Figure 15). The tensioner clip will secure and will secure and tension
the abrasive strip during use and will shold tension in the event the strip stretches
during use. If the abrasive strip is not tightly captured, the tensioner clip was not
raised sufficiently to open the jaws properly before inserting the abrasive strip.
