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.

Operation  
APPLICATIONS:  
Drilling in various metal, lumber, and plastics.  
PRE-OPERATION:  
CAUTION:  
CONFIRM THE FOLLOWING POINTS  
PRIOR TO CONNECTING THE PLUG  
TO THE POWER RECEPTACLE.  
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. Confirm the direction of bit rotation (Fig. 2):  
The drill bit rotates clockwise (when viewed from the rear)  
when the lever of the reversing switch is set to the “R”  
position, and rotates in the reverse direction when the  
lever of the reversing switch is set to the “L” position.  
(Fig. 2)  
4. Mounting drill bits:  
Tighten drill bits with the chuck wrench. There are three  
holes in which the chuck wrench should be inserted.  
Tighten them equally in turn at three holes, without  
tightening them only at one hole. The drill bits can be  
removed in the opposite method as mentioned above.  
5. How to select drill bits:  
a. When drilling holes in metals or plastics:  
Use ordinary metalworking drill bits, applicable drill  
sizes range from min 3/64” (1.2mm) to drill chuck  
capacity.  
b. When drilling holes in lumber:  
Use woodworking drill bits. For small holes of 1/4”  
(6.5mm) diam. or below, use metalworking drill bits.  
6. Installing spade handle:  
The spade handle can be installed on the back of the  
drill. Insert the bolt through the hole in the spade handle,  
locate the spade handle in the desired position and  
tighten the bolt firmly.

Operation  
PRE-OPERATION (CONTINUED):  
7. Installing the side handle:  
The side handle screws into the housing  
and two sides of the gear cover. For safe  
operation, use of the side handle is  
necessary. Especially in heavy duty drilling,  
use handle joint and side handle (Fig. 3).  
8. 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.  
(Fig. 3)  
OPERATION:  
1. Pressing force of drill:  
You can not get holes quickly even if pressing it by strong force more than  
necessary. It not only damages the tip of the drill bits and decreases the efficiency  
of operation, but also shortens the life of the drill.  
2. In case of penetrating holes:  
Drill bits are subject to break when penetrating. It is important to decrease  
pressing force when penetrating.  
3. Operation of switch:  
a. Trigger switch:  
By pulling the trigger switch, the switch is turned "ON". By pulling the trigger  
again and the trigger is released, the switch is turned "OFF".  
b. Reversing switch:  
This drill can rotate both clockwise (for drilling) and counterclockwise (for  
releasing the drill bit) by operating the reversing switch.  
CAUTION:  
NEVER CHANGE THE DIRECTION OF ROTATION WHILE THE  
MOTOR IS ROTATING. TURN THE POWER SWITCH OFF  
BEFORE CHANGING THE DIRECTION OF ROTATION.

Maintenance and Inspection  
MAINTENANCE AND INSPECTION:  
CAUTION:  
BE SURE TO SWITCH POWER OFF AND DISCONNECT THE  
PLUG DURING MAINTENANCE AND INSPECTION.  
1. Inspecting the drill bit:  
Since use of an abraded drill bit will cause motor malfunctioning and degraded  
efficiency, replace the drill bit with a new one or resharpen without delay when  
abrasion is noted.  
2. Inspecting tightness of various screws:  
Periodically inspect screw tightness of individual components. If any screws are  
loosened, securely retighten them. Loosened screws, if unheeded, may cause a  
hazardous situation.  
3. Keeping after use:  
When not in use, the Electric Drill should be kept in a dry place out of the reach of  
children.  
4. Inspecting the carbon brushes:  
The motor employs carbon brushes which are consumable parts. When the  
brushes are worn down, motor trouble may result. When the brushes are worn  
down to the limit line, replace the brushes with new ones. Keep the brushes clean,  
so that they smoothly slide into the brush holders.  
When replacing the brushes with new ones, be sure to use a pair of brushes for  
JOHN DEERE ELECTRIC DRILL ET-3504-J corresponding to the illustrated  
number.  
Auto-stop carbon brushes automatically cut off the electric circuit, when worn down  
to the wear limit. This indicates the replacement time of the brush and prevents  
damage of the commutator.
