together snugly with the bolt, washer, and nut you
previously removed (Fig. 15).
Operating Tips
•
For the best performance, operate the engine at the
maximum speed. The mower requires air to thoroughly
cut grass clippings, so do not set the height-of-cut too
low or completely surround the mower in uncut grass.
Always leave one side of the mower free from uncut
grass to allow the air to be drawn into the mower.
•
Cut the grass slightly longer than normal to ensure that
the cutting height of the mower does not scalp any
uneven ground. When cutting grass longer than 15 cm
tall, cut the lawn twice to ensure an acceptable
appearance.
•
It is best to cut only about 1/3 of the grass blade. Do not
cut more than that unless the grass is sparse or it is late
fall when grass grows more slowly.
•
Alternate the mowing direction to keep the grass
standing straight. This also helps disperse clippings and
enhances decomposition and fertilization.
•
Grass grows at different rates at different times of the
season. To maintain the same cutting height, which is a
good practice, mow more often in early spring. As the
grass growth rate slows in mid summer, mow less
frequently.
•
If the grass is longer than normal, or if it contains a high
degree of moisture, raise the cutting height higher than
usual, cut the grass at that setting, and then cut the grass
again at the lower, normal setting.
•
If you must stop the machine while mowing, you may
leave a clump of grass clippings on your lawn. To avoid
this, do the following:
–
Engage the blade and move to a previously cut area.
–
Disperse the clippings evenly by raising the mower
1 or 2 height-of-cut settings while driving forward
with the blade engaged.
•
Use the washout port to clean clippings and dirt from
the underside of the mower after each use. If grass and
dirt build up inside the mower, the cutting quality will
eventually become unsatisfactory.
•
Maintain a sharp blade throughout the season. A sharp
blade cuts grass cleanly without tearing or shredding the
grass blades. Tearing and shredding the grass turns it
brown at the edges, which slows its growth and
increases the chance of disease. Every 30 days, check
the blade for sharpness and file down any nicks.
