OPERATION

Mowing

WARNING: Before mowing, clear away sticks and stones from mowing area. Furthermore, clear away any weeds from mowing area in advance.
WARNING: Always wear the safety goggles or safety glasses with side shields when operating the mower.
CAUTION: If the cut grass or foreign object blocks up inside of the mower body, be sure to remove the lock key and battery cartridge and wear gloves before removing the grass or foreign object.
NOTICE: Use this machine for mowing lawn only. Do not mow weeds with this machine.

• Fig.35

Firmly hold the handle with both hands when mowing. The mowing speed guideline is approximately 7 to 14 meters per 10 seconds.

• Fig.36

The center lines of the front wheels are guidelines to mowing width. Using the center lines as guidelines, mow in strips. Overlap by one half to one third the previous strip to mow the lawn evenly.

• Fig.37: 1. Mowing width
• 2. Overlapping area
• 3. Center line

Change the mowing direction each time to prevent the grass grain pattern from forming in just one direction.

• Fig.38

Periodically check the grass basket for mowed grass. Empty the grass before it becomes full. Before every periodical check, be sure to stop the mower then remove the lock key and the battery cartridge.
NOTICE: Using the mower with the grass basket full prevents smooth blade rotation and places an extra load on the motor, which may cause breakdown.

Mowing a long-grass lawn

Do not try to cut long grass all at once. Instead, mow the lawn in steps. Leave a day or two between mowings until the lawn becomes evenly short.

• Fig.39

NOTE: Mowing long grass to a short length all at once may cause the grass to die. The cut grass may also block up inside of the mower body. Emptying the grass basket For models with a grass basket
