Operation

This lawn mower is intended for private residential use to cut 

grass in small lawns and gardens. This lawn mower is not 

intended to cut grass in public parks, playing fields, farms, or 

forests. Do not use this lawn mower for any application other 

than that for which it is intended.

Adjusting the Cutting Height

This electric lawn mower is equipped with a 3-position height 

adjustment system to tailor grass cutting heights of 0.98 inch, 

1.77 inch, and 2.56 inch. To change the cutting height of the 

grass, follow the instructions below. 

m

WARNING!

 Before making these adjustments, 

disconnect the power supply to the lawn mower and wait until 

the rotating blade has come to a complete standstill. Wearing 

gloves is recommended due to the close proximity of the 

cutting blade.
ALWAYS FOLLOW ALL SAFETY PRECAUTIONS AND 

RECOMMENDATIONS LISTED PREVIOUSLY IN THIS 

MANUAL.

1.  Power 

off and unplug the lawn mower.

2.  The height adjustment slots are behind each wheel. To 

adjust the height, place the lawn mower on its side. Pull 

the wheel lever out of the original slot, and insert it in 

desired slot by moving the wheel on each side (Fig. 8).

  3-Position Height Adjustment:

(1) 0.98 in. (25 mm)
(2) 1.77 in. (45 mm)
(3) 2.56 in. (65 mm)

3.  Reconnect the power supply to the lawn mower and 

resume normal use.

 NOTE: 

Make sure to adjust the two wheel levers in the 

same slot on each side to avoid an uneven cut. 

St Stopping

Do not switch on the lawn mower until it has been completely 

assembled. Before switching on the unit, always check the 

appliance cord and the extension cord for signs of damage. 

Use only intact cords.  

m

WARNING!

 Damaged cords pose a severe risk of injury. 

Replace damaged cords immediately.

m

WARNING!

 Before switching on the lawn mower, make 

sure that it is not in contact with any foreign objects. Keep 

your hands and feet a safe distance away from the rotating 

mower blade and the ejector opening. Failure to comply with 

these warnings can result in severe personal injury.
IMPORTANT: Do not start the lawn mower in tall grass.

1.  Place the unit on a level lawn surface. 
2.  Push a loop of the extension cord through the slot on the 

extension cord restraint holder from the opposite side and 

around the cord restraint hook. Insert the appliance cord 

into the extension cord (Figs. 9 – 10).

NOTE: Do not plug the extension cord into the outlet until it 

had been secured with the extension cord restraint holder and 

connected to the lawn mower's appliance cord. Only use a 

UL-rated extension cord for outdoor, all-weather use. Do not 

use an extension cord over 100 ft (30 m). See Extension Cord 

Chart on page 3.
