SLOPE OPERATION
Slopes are a major factor related to slip
and fall accidents, which can result in
severe injury. Operation on all slopes
requires extra caution. If you feel uneasy
on a slope, do not mow it.
1, Mow across the face of slopes; never
up and down. Exercise extreme
caution when changing direction on
slopes.

or other hidden objects. Uneven
terrain could cause a slip and fall
accident. Tall grass can hide
obstacles.

DOUBLE INSULATION
Your Mower is DOUBLE INSULATED to
give you added safety. This means that it
is constructed throughout with TWO
separate “layers” of electrical insulation, or
one DOUBLE thickness of insulation
between you and the tool's electrical system.
Tools built with this insulation system are
not intended to be grounded. As a result,
your mower Is equipped with a two-prong
plug which permits you to use extension
cords without concern for maintaining a
ground connection.
NOTE: DOUBLE INSULATION does not
take the place of normal safety precautions
when operating this mower. The insulation
system is for added protection against
injury resulting from a possible electrical
insulation failure within the tool.
¿CAUTION: Repair or replace damaged
cords immediately. Use only identical
Craftsman replacement parts.
POLARIZED PLUG
To reduce the risk of electric shock, this
mower has a polarized plug (one blade is
wider than the other). This mower must be
used with a suitable polarized 2 wire or 3
wire extension cord. Polarized connections
will tit together only one way. Make sure
that the receptacle end of the extension
cord has large and small blade slot
widths. If the plug does not fit fully Into the
extension cord receptacle, reverse the
plug. If it still does not fit, obtain a suitable
extension cord. If the extension cord does
not fit fully into the outlet, contact a
qualified electrician to Install the proper
outlet. Do not change the tool plug or
extension cord in any way.
EXTENSION CORDS
Double-insulated tools have 2 wire cords,
and can be used with 2 wire or 3 wire
extension cords. Only round jacketed
extension cords should be used, and we
recommend that they be listed by
Underwriters Laboratories (U.L.)

ik WARNING: To prevent eiectric shock
use only with an extension cord suitable
for outdoor use, such as SW-A, SJOW-A,
SOW-A, STW-A, STOW-A, SJW-A,
SJTW-Aor SJTOW-A.
An extension cord must have adequate
wire size (AWG or American Wire Gauge)
for safety, and to prevent loss of power
and overheating. The smaller the gauge
number of the wire, the greater the
capacity of the cable; that is, 16 gauge
has more capacity than 18 gauge. When
using more than one extension to make
up the total length, be sure each individual
extension contains at least the minimum
wire size.
To determine the minimum wire size
required, refer to the chart beiow; (Refer
to your mower’s nameplate to find the
Ampere Rating)
NOTE: Using any other length or rating or
cord will diminish the performance and
possibly the life of the eiectric motor.
