Before connecting the machine to the power source, verify that the voltage of your power supply corresponds with
the voltage specified on the I.D. nameplate located on the back of the machine. A power source with greater voltage than needed can result in serious injury to the user as well as damage to the machine. If in doubt, contact a
qualified electrician before connecting to the power source.
This tool is for indoor use only. Do not expose to rain or use in wet or damp locations.
GROUNDING INSTRUCTIONS
In the event of an electrical malfunction or short circuit, grounding
reduces the risk of electric shock to the operator. The motor of this
machine is wired for 220V single phase operation and is equipped with
a 3-conductor cord and a 3-prong grounded plug to fit a matching
grounded type receptacle, .
DO NOT MODIFY THE PLUG PROVIDED
If it will not fit your receptacle, have the proper receptacle installed
by a qualified electrician.
Check with a qualified electrician or service person if you do not completely understand these grounding instructions, or if you are not sure
the tool is properly grounded.
CIRCUIT CAPACITY
Make sure that the wires in your circuit are capable of handling the amperage draw from your machine, as well as
any other machines that could be operating on the same circuit. If you are unsure, consult a qualified electrician.
If the circuit breaker trips or the fuse blows regularly, your machine may be operating on a circuit that is close to its
amperage draw capacity. However, if an unusual amperage draw does not exist and a power failure still occurs,
contact a qualified technician or our service department.
EXTENSION CORDS
The use of an extension cord is not generally recommended for 220V. If you find it necessary, use only 3-wire
extension cords that have 3-prong grounding plug and a matching 3-pole receptacle that accepts the tool’s
plug. Repair or replace a damaged extension cord or plug immediately.
If you find it necessary to use an extension cord with your machine make sure the cord rating is suitable for the
amperage listed on the motor I.D. plate. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. The accompanying chart shows the correct size extension cord to be used based on cord
length and motor I.D. plate amp rating. If in doubt, use the next heavier gauge. The smaller the number, the heavier
the gauge.

plan for placement within your shop that will allow the
operator to work unencumbered and unobstructed by
foot traffic (either passing shop visitors or other shop
workers) or other tools or machinery.
Figure 1
ESTABLISHING A SAFETY ZONE
For shops with frequent visitors or multiple operators, it is
advisable to establish a Safety Zone around shop machinery. A clearly defined “no-go” zone on the floor around
each machine can help avoid accidents that could cause injury to either the operator or the shop visitor. It is advisable to take a few moments to either paint (using non-slip paint) or using tape, define on the floor the limits or
perimeter of each machines safety zone. Take steps to ensure that all operators and shop visitors are aware that
these areas are off limits whenever a machine is running for everyone but the individual operating the unit.

TO LOCK
OFF
The magnetic safety switch on this sander is equipped with an overload protection feature. To prevent an electrical
overload from damaging the motor, in the event of a spike in line voltage or amperage draw, the internal overload
protector will automatically be tripped, thereby cutting off power to the motor.
Note: The most common causes of such overloads are:
1. Overworking the motor by attempting to remove too much material in a single pass, thereby causing an increase in power consumption and a spike in amperage draw.
2. An electrical extension cord that is too long or not the correct gauge of wire, which can also cause an increase
in amperage draw. If an electric extension cord must be used, follow the instructions and refer to the chart in
the electrical requirements section at the beginning of this manual.
3. Overworked circuit caused by operating on a circuit that is close to its amperage draw capacity. Make sure the
circuit being used 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 qualified electrician.
To reset the overload protection switch after it has been tripped proceed as follows:
To avoid unexpected or unintentional start-up be certain that both of the power switches have been set to the off
position before re-setting the overload protection switch.
SWITCHES OFF
1. Set both of the power switches on the sander to the

Experiment with feed speeds based on the workpiece material, depth of sanding as well as sanding belt grit to find
which setting work best for your needs. As a general guideline however, for best results, more aggressive sanding
using lower grits or sanding wider boards should be done at slower speeds and sanding using higher grits or sanding narrow boards can be done at higher speeds.
BASIC FUNCTIONS OF THE UNIT
This drum sander is designed for surface sanding of wooden cabinet doors, flat wooden panels, wide glue-ups and
other natural wood products only. This sander is not intended (and should not be used) to sand any material other
than wood.
BASIC PRINCIPLES OF SANDING
It is always preferable to remove less material per pass and take multiple passes. This can extend sanding belt life,
place less strain on the motor and provide better workpiece finish quality.
11
Do not use this sander as a thickness planer. Never attempt to remove more than the depth of the grain of the sanding belt in any single pass. Too much friction will cause belt to overheat and wear prematurely, and, in extreme
cases, may cause burns in the workpiece.
Note: To avoid overworking the motor, creating a potential circuit overload, or damaging the sanding drum, do
not force the workpiece against or into the drum. For better finish results and to avoid potential damage to the
sander or the workpiece, let the workpiece feed into the sander at the rate of feed to which the conveyer is set.
OPERATING INSTRUCTIONS
CHECKLIST BEFORE STARTING
Make sure to have on safety glasses as well as hearing and respiratory protection at all times when using the
sander.
Make sure you and any assistants are wearing safe appropriate workshop attire. Roll up long sleeves, secure long
hair and remove any jewelry: watches, rings, bracelets or anything that could become caught in the conveyor feed
rollers or the drum, potentially causing serious injury.
• Make sure a dust collector is properly attached.
• If multiple boards are to be sanded, collect all workpieces together and set them nearby on a table or bench
within easy reach.
• Make sure that the sanding belt is properly installed, that is, wound around the drum, taut and without spaces
between the belt edges. Otherwise, the sanding belt may rip when in contact with the workpiece.
DO
DO NOT
• If working with longer workpieces, make sure to have adequate out feed support safely set-up and ready
before sanding.
Tip: To avoid sanding snipe – which is a small depression in the surface of a workpiece across its width caused by a
variation in the sanding depth during a given pass - it is important to keep the workpiece level on the feed table until
it has completely cleared contact with the sanding drum. It is advisable to use an outfeed table or some form of outfeed support when sanding workpieces of 4’ or more in length. Allowing the leading edge of a longer workpiece to hang
or sag off of the outfeed end the conveyor table should be avoided as it will lift the trailing end of the workpiece up
into the sanding drum and cause uneven sanding depth and snipe.

OPERATIONS STEP-BY-STEP
To reduce the risk of damage to the sander or the workpiece, as well as a potential for personal injury, after initial
set-up as well as before each use, make sure that everything is securely installed and that all fasteners and moving parts on this sander are locked in place before starting the machine.
1. Place the workpiece on the conveyor belt.
2. Set the height of the conveyor table. (see previous section: “Raising/Lowering the Conveyor Table”)
3. Remove the workpiece from the conveyor belt.
4. Turn on your dust collector.
Always turn on the dust collector BEFORE starting the sander.
5. Press the green "ON" button on the control box to start sanding drum motor.
6. Insert the safety key into the conveyor belt switch.
7. Set the feed speed to minimum before starting the conveyor belt, then lift the switch up to start the conveyor
motor. Gradually increase the speed , until you reach the desired feeding speed.
8. Place the workpiece on the center of the conveyor belt and pass the board twice.
Keep hands away from the rotating drum and conveyor belt. Do not force the workpiece towards the sanding
drum, let the conveyor belt feed the workpieces.
Tip: For better workpiece finish quality, make shallower passes with the conveyor table height adjusted so you just start
hearing the contact noise.
9. Step to the rear of the machine and pick up the workpiece on the out feed.
Note: Consider using a proper support on the out feed for workpieces longer than 4'.
TO STOP THE MACHINE
1. Press the red "OFF" button, on the control box to stop the rotation of the drum.

Keep threaded rods, , and gears, , located at either end of the machine, , greased and free of dust or debris.
Clean and remove dust, debris, and old grease after every 10-15 hours of use. After cleaning, re-apply a generous
coating of any common automotive bearing grease.
PERIODIC MAINTENANCE
1. Inspect/test the ON/OFF switches before each use. Do not operate the sander with a damaged switch; replace
a damaged switch immediately.
2. Keep the machine, especially motor and conveyor, as well as the feed table conveyor clean and free of dust
or glue. Vacuum or brush off any loose debris and wipe down the machine and the conveyor occasionally
with a damp rag.
3. The drum must always be kept clean. Dirt on the drum will cause belt slippage.
4. The motor and drum bearings are sealed and permanently lubricated – no further lubrication is required.
5. Periodically inspect the power cord and plug for damage, as well as the sanding belt, the drum, the motor pulleys drive belt and the conveyor belt.
Never operate the sander with any damaged part. Replace a damaged part at the first visible signs of damage.
REQUIRED MAINTENANCE
MOUNTING AND REPLACING THE SANDING BELT
Sanding belt should be replaced when worn out.
Pre-cut replacement belts can be purchased in a variety of grits from your General® International dealer under the
following parts numbers:
• 36 grit - 15-251 • 120 grit - 15-255
• 60 grit - 15-252 • 150 grit - 15-256
• 80 grit - 15-253 • 180 grit - 15-257
• 100 grit - 15-254 • 220 grit - 15-258

3. Tightly wind the sanding belt around the drum, making sure that there are no spaces between the edges, ,
of the sanding belt, that the belt is taut and that there are no bumps, . Do not overlap the edges, .
16
Note: The spring-loaded clamp at the right end of the drum is a two stage spring. The first stage grabs the paper
and the second stage pulls the clamp backward inside the drum, providing proper tension to the sanding belt.
FIRST STAGE SECOND STAGE
5. Push and hold the right spring-loaded clamp forward with your thumb.
6. Insert the right tab of the sanding belt in the slot,
pushing all the way in (as far as possible), until it is
tight, .
Tip: Use a flat stick or any similar non-cutting object to force the tab further into the slot so it is as tight as possible, .
Note: On occasion, due to slight variations in the length of the sanding belt or the depth of installation in the left
belt clamp, even with the belt properly wound onto the drum, there may be slightly too much belt left at the right
end of the drum. This may cause a slight overlap on the last wrap on the drum, , and this despite installing the
right end of the belt as far into the clamp as it will go. In such cases, to avoid having to unroll and realign the
entire belt on the drum after it has already been secured at both ends and is otherwise properly installed, use a
utility knife or scissors to cut and remove the overlapped section of paper. To avoid belt tearing during sanding,
avoid cutting at
right angles, , - make a rounded or curved cut, . (See pictures below.)
7. Release only the first stage of the clamp, sliding
your thumb down towards the bottom to lock the
tab in place.
8. Release the clamp, . This will bring proper tension, , to the sanding belt.

Note: With the sanding belt tab properly inserted in the clamp, the clamp assembly should not pull back more than 3/4"
from the slot in the drum. If the clamp assembly pulls back further than 3/4" the sanding belt tab, , needs to be inserted
further into the clamp to remove some of the slack in the belt, . Otherwise the paper will not be properly tensioned on
the drum and the belt may loosen, unwind, or possibly tear when it comes in contact with the workpiece. (See images
above.)
9. Once the sanding belt has been properly installed and tensioned on the drum, close and lock the drum cover.
DRUM MOTOR BELT REPLACEMENT
The sanding drum is driven by a belt mounted on pulleys powered by the motor. If the belt becomes too loose due
to wear or if a breakage occurs, you must replace it as follows:
1. Unscrew and remove the front panel, , and both
side panels, .
Proceed with caution. Removing the belt from the pulley will cause the motor to swing freely under it’s own weight
