parts, mounting, and any other conditions that may affect its operation. A guard or  
other part that is damaged should be properly repaired or replaced by a John Deere  
Dealer unless otherwise indicated elsewhere in this instruction manual. Have  
defective switched replaced by a John Deere Dealer. Do not use tool if switch does  
not turn it on and off.  
AVOID USING A POWER TOOL FOR APPLICATIONS OTHER THAN THOSE  
SPECIFIED  
Never use a power tool for applications other than those specified in the instruction  
manual.  
ENSURE SAFE OPERATION THROUGH CORRECT HANDLING  
Secure safe operation through correct handling by observing the instructions de-  
scribed herein. Do not employ accessories other than those specified herein;  
otherwise, a hazardous condition may be created. Never allow a power tool to be  
used by persons not familiar with correct handling (such as children) or by those who  
cannot handle the tool correctly.  
CONFIRM THAT NO ITEMS SUCH AS AN ELECTRIC CABLE OR CONDUIT ARE  
BURIED INSIDE  
In places where live wiring may be hidden behind a wall, floor, ceiling, etc. do not hold  
or contact any metal parts of the tool. In such cases, metal parts could become  
electrically live and present a serious shock hazard.  
KEEP THE RIGHT PARTS IN THE RIGHT POSITION  
Do not remove covers and screws which have been factory-mounted. They perform  
important respective roles. Keep them in the right positions.  
SHOULD THE PLASTIC HOUSING OR HANDLE OF A POWER TOOL BE  
CRACKED OR DEFORMED, DO NOT USE IT

CAUTION  
ALWAYS KEEP THE MOTOR AIR VENT FULLY OPENED  
A constantly open motor air vent is necessary to allow air to come in and out for cooling  
the motor. Do not allow it to become clogged up, even if dust is blown through it.  
OPERATE POWER TOOLS AT THE RATED VOLTAGE  
Operate power tools at voltages specified on the nameplates.  
STOP OPERATION IMMEDIATELY IF ANY ABNORMALITY IS DETECTED  
Should a power tool be detected as out of order or should other abnormalities be  
observed during operation, stop using the tool immediately.  
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF.  
Don't leave tool until it comes to a complete stop.  
CAREFULLY HANDLE POWER TOOLS  
Should a power tool be dropped or struck against hard materials inadvertently, it may be  
deformed, cracked, or damaged.  
DO NOT WIPE PLASTIC PARTS WITH SOLVENT  
Solvents such as gasoline, thinner, benzine, carbon tetrachloride, and alcohol may  
damage and crack plastic parts. Do not wipe them with such solvents. Wipe plastic  
parts with a soft cloth lightly dampened with soapy water.  
WHEN REPLACING A COMPONENT PART, ADOPT THE SAME TYPE  
When replacing a component part with a new one, adopt the same type of new part.  
Also, never attempt to repair a power tool yourself.  
POLARIZED PLUGS  
To reduce the risk of electric shock, this equipment has a polarized plug (one blade is  
wider than the other).  
This plug will fit in a polarized outlet only one way.

CAUTION  
EXTENSION CORD  
Make sure your extension cord is in good condition. When using an extension cord, be  
sure to use one heavy enough to carry the current your product will draw. An undersized  
cord will cause a drop in line voltage resulting in loss of power and overheating. Table  
shows the correct size to use depending on cord length and nameplate ampere rating. If  
in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

ENVIRONMENT WHERE ELECTRIC SHOCK IS POSSIBLE.  
DOUBLE INSULATION SYSTEM ENHANCES SAFE OPERATION  
DOUBLE INSULATION  
To enhance safe operation of this electric power tool, JOHN DEERE has adopted a  
double insulation system. The term "double insulation" used here denotes an insulation  
systems with two insulations physically separated and arranged between the electrically  
conductive material connected to the power supply and outer frame subject to contact by  
the operator.  
Thus, the power tool is termed double insulated and both the mark and "  
insulation", or either one is indicated on the name plate.  
" double  
While no external grounding is required with this system, normal safety precautions as  
outlined in this manual must still be followed.  
To maintain the effectiveness of the double insulation system, follow the precautions  
described below:  
1. Always contact your John Deere Dealer when assembling, disassembling or  
replacing parts other than accessories or carbon brushes. Improper assembly  
and/or replacement with wrong parts may result in eliminating the double  
insulation-feature.  
2. Clean the exterior of the tool with a soft cloth moistened with soapy water, and  
dry thoroughly. Choleric solvent, gasoline, and thinner will cause plastic compo  
nents to dissolve.

PRE-OPERATION:  
Before using the Electric Power Tool, complete the following preparations.  
CAUTION:  
CONFIRM THE FOLLOWING POINTS PRIOR TO CONNECTING  
THE PLUG TO THE POWER SOURCE.  
1. Confirm the applied power source:  
Be sure to operate the Electric Power Tool in the voltage specified on the name  
plate.  
2. Confirm that the power switch is turned "OFF":  
If the plug is connected to the power receptacle while the power switch is turned  
"ON", the machine starts operating unexpectedly, inviting serious accidents. Prior  
to using the Electric Power Tool, be sure to confirm that the power switch is turned  
"OFF".  
3. Extension cord:  
When the work area is far away from the power source, use an extension cord of  
sufficient thickness and rated capacity. The extension cord should be kept as  
short as possible.  
CAUTION:  
DAMAGED CORD MUST BE REPLACED OR REPAIRED.  
4. Confirming condition of the environment:  
Confirm that the work site is placed under appropriate conditions conforming to  
prescribed precautions.  
5. Confirm the power receptacle:  
If the power receptacle only loosely accepts the plug, the receptacle must be  
repaired. Contact the nearest electric store for repair service. If such a faulty  
receptacle is used, it may cause overheating, resulting in a serious hazard.  
6. Attach sanding belt:  
For details, refer to the item “HOW TO HANDLE SANDING BELT”  
PRECAUTIONS ON USING BELT SANDER  
1. Align the inside arrow mark of the sanding belt with the revolving direction of the

2. To turn on switch:  
Turn on switch while holding machine away from surface to be worked on. If  
machine is placed on surface when switch is pushed, surface may be badly  
scratched. The same applies when stopping the machine.  
3. How to hold the machine:  
Grasp handle and handle knob and hold machine against surface to be worked on  
so that it contacts surface lightly.  
Weight of machine itself is sufficient for sanding and polishing at highest efficiency.  
Do not apply any additional pressure, for this would place unnecessary  
load on motor, shortening life of sanding belt and lower work efficiency.  
4. How to move machine:  
Move machine forward first and then backward, repeating this motion.  
5. How to select the proper sanding belt:  
Choose sanding belt of proper grain size and grain type for your specific purpose,  
by referring to the tables below (Table 1 and Table 2):

Operation  
OPERATION (CONTINUED):  
DUST REMOVAL:  
When an excessive amount of dust is deposited in the  
dust bag, dust-collecting efficiency will sharply drop.  
Remove dust from the bag when it is deposited up to  
about 2/3 the bag capacity, where by dust collecting  
efficiency (as well as working efficiency) will be ensured.  
Remove dust from the bag as follows:  
a. Loosen the support bar and remove the dust  
bag.  
b. The bag inlet can be opened by unzipping the  
slide fastener.  
Maintenance and Inspection  
MAINTENANCE AND INSPECTION:  
CAUTION: BE SURE TO SWITCH POWER OFF  
AND DISCONNECT THE PLUG  
DURING MAINTENANCE AND  
INSPECTION.  
1. Inspecting the Sanding Belts:  
If the sanding belt becomes loaded with debris or  
dull, the efficiency will drop significantly. It may be  
necessary to clean or replace the sanding belt  
frequently, depending on the type of use.  
2. Inspecting the mounting screws:  
Regularly inspect all mounting screws and ensure  
that they are properly tightened. Should any of the  
screws be loose, retighten them immediately. Failure  
to do so could result in serious hazard.  
(Fig. 6)  
3. Inspecting the carbon brushes (Fig. 6):  
The motor employes carbon brushes which are consumable parts. Since an  
excessively worn carbon brush could result in motor trouble, replace the carbon brush  
with a new one which has the same carbon brush No. shown in figure when it  
becomes worn to or near the “wear limit”. In addition, always keep carbon brushes  
clean and ensure that they slide freely within the brush holders.  
4. Replacing a carbon brush:  
Disassemble the brush cap with a minus-head screwdriver. The carbon brush can  
then be easily removed.
