USE OF 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.

WARNING: AVOID ELECTRICAL SHOCK HAZARD. NEVER USE THIS
TOOL WITH A DAMAGED OR FRAYED ELECTRICAL CORD
OR EXTENSION CORD.
INSPECT ALL ELECTRICAL CORDS REGULARLY. NEVER
USE IN OR NEAR WATER OR IN ANY ENVIRONMENT WHERE
ELECTRIC SHOCK IS POSSIBLE.
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 “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 a AUTHORIZED JOHN DEERE 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 thinners
on plastic components; otherwise the plastic may dissolve.
