SAVE THESE INSTRUCTIONS AND MAKE THEM AVAILABLE TO
OTHER USERS AND OWNERS OF THIS TOOL!
OPERATE POWER TOOLS AT THE RATED VOLTAGE
Operate the power tool at voltages specified on its nameplate.
If using the power tool at a higher voltage than the rated voltage, it will result in
abnormally fast motor revolution and may damage the unit and the motor may burn
out.
NEVER USE A TOOL WHICH IS DEFECTIVE OR OPERATING ABNORMALLY
If the tool appears to be operating unusually, making strange noises, or otherwise
appears defective, stop using it immediately and arrange for repairs by a JOHN
DEERE AUTHORIZED DEALER.
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 and dry
thoroughly.
DOUBLE INSULATION FOR SAFER OPERATION
To ensure safer operation of this power tool, JOHN DEERE has adopted a double
insulation design. “Double insulation “ means that two physically separated insulation
systems have been used to insulate the electrically conductive materials connected to
the power supply from the outer frame handled by the operator. Therefore, either the
symbol “ ” or the words and “Double insulation” appear on the power tool or on the
nameplate.
Although this system has no external grounding, you must still follow the normal
electrical safety precautions given in this Instruction Manual, including not using the
power tool in wet environments.
To keep the double insulation system effective, follow these precautions:
a. Only JOHN DEERE AUTHORIZED DEALER should disassemble
or assemble this power tool, and only genuine JOHN DEERE replacement
parts should be installed.
b. Clean the exterior of the power tool only with a soft cloth moistened with
soapy water, and dry thoroughly.
Never use solvents, gasoline or thinner on plastic components; otherwise the plastic
may dissolve.
