CordRestraint
The cord restraint is located on the back of the upper
handle and when used properly, helps to protect the
motor/blade control assembly and also the extension
cord powering the unit.
HeightAdjustment L ever
A height adjustment lever at each wheel provides
cutting height adjustment. Each adjuster has nine
height positions. Height of cut will be changed when the
lever is moved from one position to another. Simply
depress the lever towards wheel and move wheel and
lever assembly to desired position. All wheels must be
placed in the same relative position.

ExtensionCordSelection
Shown below is the length of extension cord and its
corresponding acceptable cord ratings.
• 50' Cord -- use 12 AWG
The extension cord should be a UL listed cord set
suitable for outdoor use.
IMPORTANT: Using any other length or rating of cord will
diminish the performance and possibly the life of the
electric motor, and may also cause breakers to trip or
fuses to blow in your home's fusebox.
Cord Restraint
Attach the extension cord (not provided with unit) to
the cord restraint as follows.
Form a small loop in the extension cord. Allow
enough excess cord to make the connection to the
motor/blade control (approximately 20 inches).
Slip the loop through the slot on the bottom of the
cord restraint, and up over the tab, to prevent
disconnection from the motor/blade control during
operation.
Keep the cord restraint as close to the motor/blade
control as possible. See Figure 9.
Connectingto the Motor/Blade ControlAssembly
Connect the plug on the extension cord fully onto the
plug on the mower. The mower is equipped with a
polarized AC power plug (one blade of the plug is wider
than the other), which will fit into the plug on the
extension cord only one way. If unable to make a full
connection, try reversing the plug on the extension
cord. Should the plugs still fail to fit, contact your
service dealer for assistance. Do not defeat the safety
purpose of the polarized plug.
Connecting to the ElectricPower Source
WARNING: This mower should be operated on a
15 AMP circuit. If you experience difficulty in
stading with a standard 15 AMP fuse or circuit
breaker, contact you nearest authorized service
facility. Do not use a higher rated fuse or breaker
without consulting your power company.
Plug the extension cord into any convenient 110-120
volt 60 cycle A.C. outlet or receptacle for your source of
power. This outlet may be located either out-of-doors or
indoors. To avoid blowing fuses, pick an outlet that is
not overloaded. Your mower will operate satisfactorily
on a circuit that is fused for 15 amperes. Do not use
oversize fuses without consulting an electrician. If an
inside receptacle is used, the extension cord can be
taken out either through the doorway or a window.
Starting the MotorandBlade
NOTE: The wheels on your unit are set in a low cutting
height position for shipping purposes. For best results,
raise the cutting position until it is determined which
height is best for your lawn. See cutting height
adjustment in the Making Adjustments section.
