Model SB1102 SAFETY
Additional Drum Sander Safety
Serious injury or death can occur from getting hands trapped between workpiece and conveyor table
and being pulled into machine, or becoming entangled in rotating parts inside machine. Workpieces
thrown by sander can strike nearby operator or bystanders with significant force. Long-term
respiratory damage can occur from using sander without proper use of a respirator. To reduce the risk
of these hazards, operator and bystanders MUST completely heed the hazards and warnings below.
Avoiding Entanglement: Tie back long hair,
remove jewelry, and do not wear loose
clothing or gloves. These can easily get
caught in moving parts. Never reach
inside machine or try to clear jammed
workpiece while machine is operating.
Keep all guards in place and secure.
Workpiece Material: This sander is designed to
sand only natural wood products or man-
made products made from natural wood
fiber. DO NOT sand any metal products.
Workpiece Inspection: Nails, staples, knots,
or other imperfections in workpiece can
be dislodged and thrown from sander
at high rate of speed into operator or
bystanders, or cause damage to sandpaper
or sander. Never try to sand stock that has
embedded foreign objects or questionable
imperfections.
Kickback: Occurs when a workpiece is ejected
out the front of sander at a high rate of
speed toward operator or bystanders. To
reduce risk of kickback-related injuries,
always stay out of workpiece path, only
feed one board at a time, and always
make sure pressure rollers are properly
adjusted below sanding roller. Never sand
workpieces below minimum specifications
listed in Machine Data Sheet.
Feeding Workpiece:
Placing fingers between
workpiece and conveyor can result in
pinching injuries, or possibly getting
trapped and pulled into sanding area of
machine. DO NOT place fingers under
bottom of workpiece while feeding it into
sander.
Sanding Dust:
Sanding creates large amounts of
fine airborne dust that can lead to eye injury
or serious respiratory illness. Reduce your
risk by always wearing approved eye and
respiratory protection when sanding. Never
operate without adequate dust collection
system in place and running. However, dust
collection is not a substitute for using a
respirator.
Power Disconnect:
An accidental startup while
changing sanding belts or performing
adjustments or maintenance can result
in serious entanglement or abrasion
injuries. Make sure machine is turned
OFF, disconnected from power and air, and
all moving parts are completely stopped
before changing belts, doing adjustments, or
performing maintenance.
Sandpaper Contact:
Rotating sandpaper can
remove a large amount of flesh quickly.
Keep hands away from rotating sanding
drum(s) during operation. Never touch
moving sandpaper.
No list of safety guidelines can be complete. Every shop environment is different. Always consider
safety first, as it applies to your individual working conditions. Use this and other machinery with
caution and respect. Failure to do so may result in serious personal injury or property damage.

Power Supply
Power Supply
Requirements
Electrocution or fire may
occur if machine is not
correctly grounded and
attached to the power
supply. Use a qualified
electrician to ensure a safe
power connection.
Before installing the machine, consider the
availability and proximity of the required power
supply circuit. If an existing circuit does not meet
the requirements for this machine, a new circuit
must be installed.
To minimize the risk of electrocution, fire,
or equipment damage, installation work and
electrical wiring must be done by a
n electrician
or qualified service personnel
in accordance with
applicable electrical codes and safety standards.
Availability
The full-load current rating is the amperage
a machine draws at 100% of the rated output
power. On machines with multiple motors, this is
the amperage drawn by the largest motor or sum
of all motors and electrical devices that might
operate at one time during normal operations.
The full-load current is not the maximum
amount of amps that the machine will draw. If
the machine is overloaded, it will draw additional
amps beyond the full-load rating.
If the machine is overloaded for a sufficient
length of time, damage, overheating, or fire may
result—especially if connected to an undersized
circuit. To reduce the risk of these hazards,
avoid overloading the machine during operation
and make sure it is connected to a power supply
circuit that meets the requirements in the
following section.
Full-Load Current Rating
Full-Load Rating at 220V................... 27 Amps

PREPARATION
Grounding Requirements
This machine must be grounded! In the event
of
certain types of malfunctions or breakdowns,
grounding provides a path of least resistance
for electric current
in order to reduce the risk of
electric shock.
This machine is equipped with a power cord
that has
an equipment-grounding wire and a
grounding plug
(similar to the figure below).
The plug
must only be inserted into a matching
receptacle (outlet)
that is properly installed and
grounded in accordance with all local codes and
ordinances.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without
yellow stripes) is the equipment-grounding wire.
If repair or replacement of the power cord or
plug is necessary, do not connect the equipment-
grounding wire to a live (current carrying)
terminal.
Check with an electrician or qualified service
personnel if you do not understand these
grounding requirements, or if you are in doubt
about whether the tool is properly grounded.
If you ever notice that a cord or plug is
damaged or worn, disconnect it from power, and
immediately replace it with a new one.
Extension Cords
Minimum Gauge Size............................10 AWG
Maximum Length (Shorter is Better) ....50 ft.
We do not recommend using an extension cord
with this machine. If you must use one, only
use it if absolutely necessary and only on a
temporary basis.
Extension cords cause voltage drop, which may
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine
must contain a ground wire, match the required
plug and receptacle listed in the
Circuit
Requirements
for the applicable voltage, and
meet the following requirements:

HEAVY LIFT!
This machine and its parts
are heavy! Serious personal
injury may occur if safe
moving methods are not
used. To reduce the risk of
a lifting or dropping injury,
ask others for help and use
power equipment.
Assembly
This machine must be fully assembled before it
can be operated. Before beginning the assembly
process, refer to Required for Setup and gather
all listed items. To ensure the assembly process
goes smoothly, first clean any parts that are
covered or coated in heavy-duty rust preventative
(if applicable).
1. Loosen pre-installed hex bolt, and remove
cardboard protection from base of control
panel pedestal.
2. Carefully rotate control panel to upright
position and attach pedestal to side of
machine with (3) 3⁄8"-16 x 2" hex bolts and
(3) 3⁄8" flat washers, plus the hex bolt and
flat washer that was loosened in Step 1, as
shown in Figure 8.

PREPARATION
4. Apply
1⁄16" double sided tape to bottom
perimeter of each dust port, then attach to
dust hood as shown in Figure 10.
5. Secure dust ports to dust hood with
(8) #8 x 1⁄2" tap screws and (8) #8 flat
washers.
3. Attach handwheel to spindle and tighten
pre-installed set screw, then attach
handwheel handle (see Figure 9).
Dust Collection
1. Fit (2) 4" dust hoses over dust ports as
shown in Figure 11 and secure in place with
(2) hose clamps.
Minimum CFM at each Dust Port: 400 CFM
Do not confuse this CFM recommendation
with the rating of the dust collector. To
determine the CFM at the dust port, you
must consider these variables: (1) CFM
rating of the dust collector, (2) hose type
and length between the dust collector and
the machine, (3) number of branches or
wyes, and (4) amount of other open lines
throughout the system. Explaining how
to calculate these variables is beyond the
scope of this manual. Consult an expert or
purchase a good dust collection "how-to"
book.
This machine creates a lot of wood chips/
dust during operation. Breathing airborne dust
on a regular basis can result in permanent
respiratory illness. Reduce your risk by
wearing a respirator and capturing the dust
with a dust-collection system.
2. Tug hoses to make sure they do not come
off. A tight fit is necessary for proper
performance.

Model SB1102 OPERATION
Operation Overview
Loose hair, clothing, or
jewelry could get caught
in machinery and cause
serious personal injury.
Keep these items away
from moving parts at all
times to reduce this risk.
To reduce the risk of
serious injury when using
this machine, read and
understand this entire
manual before beginning
any operations.
The purpose of this overview is to provide
the novice machine operator with a basic
understanding of how the machine is used during
operation, so they can more easily understand
the controls discussed later in this manual.
Note:
Due to the generic nature of this overview,
it is not intended to be an instructional guide
for performing actual machine operations.
To learn more about specific operations and
machining techniques, seek training from people
experienced with this type of machine, and do
additional research outside of this manual by
reading "how-to" books, trade magazines, or
websites.
1. Examines workpiece to verify it is suitable
for sanding and determines which sandpaper
grit size to use.
2. Verifies workpiece has necessary outfeed
clearance and support. If workpiece is overly
long and difficult to handle, operator uses a
roller support stand or an assistant to assist
with feeding.
3. Adjusts table height to approximate
workpiece thickness.
Note: During initial pass with a new
workpiece, operator adjusts table height
as necessary so workpiece only makes light
contact with sanding drums and does not
overload sander.
4. Puts on safety glasses, respirator, and any
other required protective equipment.
5. Starts dust collection system and then drum
sander. Waits for sanding drums to reach
full speed and then sets conveyor speed for
the specific type and finish of workpiece.
6. Feeds workpiece into sander by placing front
end on infeed side of conveyor table and
supporting back end until workpiece engages
with pressure rollers. Adjusts conveyor speed
as needed to maintain safe amperage level.
7. Receives workpiece from outfeed side of
conveyor table.
8. Raises height of conveyor table a small
amount (typically 1⁄4rotation of handwheel),
then repeats the feeding process of workpiece
through sander.
9. Changes sandpaper to a finer grit, as needed.
10. Repeats Steps 6–9as needed, turns sander
OFF, then disconnects it from power.
To reduce risk of eye injury
from flying chips or lung
damage from breathing dust,
always wear safety glasses
and a respirator when
operating this machine.
To complete a typical sanding operation, the
operator does the following:
