Edge Mowing; Maintenance - Makita ELM4121 Instruction Manual

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.35
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.

Edge mowing

When mowing at the edge, be sure to face the left side
of the machine toward the edge, and then move the
machine along the edge.
