battery when the product is not in operation.

• Push the lock button (A) and pull the battery straight

out. (Fig. 35)

To get a good result

• Always use a sharp blade. A blunt blade gives an

irregular result and the cut surface of the grass

becomes yellow. A sharp blade also uses less

energy than a blunt blade.

• Do not cut more than ⅓ of the length of the grass.

Cut first with the cutting height set high. Examine the

result and lower the cutting height to an applicable

level. If the grass is very long, drive slowly and cut 2

times if necessary.

• Cut in different directions each time to prevent

stripes in the lawn.

• Keep the cutting cover clean. Buildup from grass

and dirt on the inner side of the cutting cover can

decrease the cutting result. Refer to

To clean the

inner surface of the cutting cover on page 12

.
