①
Cautions for operation of mower
(1) If you operate the mower for the first time, or
not accustomed to the machine, learn how to
operate on a flat surface before operating it.
(2) Determine a mowing method properly
according to the size or shape of the field,
layout of trees or other objects. Generally,
cut the grass of several lines from the
periphery clockwise and then toward the
center counterclockwise.
②
Cutting the grass
(1) Start the engine.
(Refer to page 32, How to start)
(2) Move the machine to the point to start
cutting.
(See page 34, How to start)
(3) Shift the speed change lever to Low speed.
(4) Increase the engine speed to the highest
value.
(5) Push the cutting button to light up the lamp.
(6) By pulling down the lifting/lowering lever to
the auto side, the mower lowers. When the
mower approaches the ground, the rotary
blades turn.
(7) Step the front side of the running pedal to cut
the grass.
(8) Upon completion of cutting, pull up the
lifting/lowering lever to lifting side to lift up the
mower.
Caution
● After completion of cutting operation, be sure
to turn off the cutting button lamp.
Danger
● While the rotary blades are rotating, never
bring your hands or feet close to the mower
unit.
④
Cutting speed
Always keep the highest rotating speed of the
cutting blades for smooth cutting operation. By
setting the accelerator lever of the machine to
the highest engine speed position, highest speed
of the cutting blades and the highest output of
the engine can be obtained. Select the operating
speed of the machine depending on the grass
condition, finish, experience of the operator and
other conditions. Avoid cutting operation under
overload.
⑤
Cutting operation on a slope
Danger
● Do not operate the machine where the
machine may turn over or slip.
Just after the rain, the machine is apt to slip.
Do not operate the machine under such a
condition.
● When operating the machine on a slope,
understand the entire terrain of the ground in
advance.
● Turn the machine at a place of gentler slope
angle
● Do not operate the machine on a steep slope
more than 20 degrees.
