Operation
OPERATION:
CAUTION: TO PREVENT ACCIDENTS, MAKE SURE TO TURN THE SWITCH
OFF AND DISCONNECT THE PLUG FROM THE RECEPTACLE
WHEN THE DRILL BITS AND OTHER VARIOUS PARTS ARE
INSTALLED OR REMOVED. THE POWER SWITCH SHOULD
ALSO BE TURNED OFF DURING A WORK BREAK AND AFTER
WORK.
1. Switch operation:
a.
When the trigger switch is depressed, the tool rotates. When the trigger is
released, the tool stops.
b. The rotational speed of the drill can be controlled by varying the amount that
the Trigger switch is pulled. Speed is low when the trigger switch is pulled
slightly and increases as the trigger switch is pulled more.
c. Pulling the trigger and pushing the stopper, it keeps the switched-on condition
which is convenient for continuous running. When switching off, the stopper
can be disconnected by pulling the trigger again.
2. Electric brake (ET-3505-J):
When releasing the trigger of the switch, the brake will be applied for immediate
stopping.
CAUTION: AS THERE IS SOME REACTION WHEN THE BRAKE
FUNCTIONS, BE SURE TO HOLD THE DRILL SECURELY.
WHEN THE BRAKE BECOMES INEFFECTIVE, SEND THE TOOL
TO AN AUTHORIZED JOHN DEERE DEALER.
3. Drilling:
a.
When drilling, start the drill slowly, and gradually increasing speed as you drill.
b. Always apply pressure in a straight line with the bit. Use enough pressure to
keep drilling, but do not push hard enough to stall the motor or deflect the bit.
c. To minimize stalling or breaking through the material, reduce pressure on drill
and ease the bit through the last part of the hole.
d. If the drill stalls, release the trigger immediately, remove the bit from the work
and start again. Do not click the trigger on and off in an attempt to start a
stalled drill. This can damage the drill.
e. The larger the drill bit diameter, the larger the reactive force on your arm.
Be careful not to lose control of the drill because of this reactive force.
To maintain firm control, establish a good foothold, use side handle, hold the
drill tightly with both hands, and ensure that the drill is vertical to the material
being drilled.
