Cord Restraint
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.
Height Adjustment Lever
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.

Cord Connection
Extension Cord Selection
Shown below is the length of extension cords and its
corresponding acceptable cord ratings.
50’ Cord — use 16 AWG
100’ Cord — use 14 AWG
150’ Cord — use 12 AWG
The extension cord should be a CUL 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 fuse box.
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.
Connecting to the Motor/Blade Control Assembly
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 is wider than the
other), which will fit into the plug on the extension cord
only one way. If unable to make a connection, try
reversing the extension cord plug. 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 Electric Power Source
WARNING: This mower should be operated on a
15 AMP circuit. If you experience difficulty in
starting with a standard 15 A 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 V
60 cycle AC outlet or receptacle for your source of
power. This outlet may be located either outdoors 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 Motor and Blade
NOTE: The wheels on your unit are set in a low cutting
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.
