Overload protection
This machine is equipped with overload protection, and it
functions under the following situations:
• The cutting tool becomes clogged because scarified
materials are built up around it.
• The machine is trying to scarify more than the motor
can handle.
• Something hinders the rotation of the cutting tool.
When this protection works, the machine is switched off
automatically.
If it happens, unplug the machine, wait until it cools down,
and remove the cause of the overload before restarting
the machine.
OPERATION
Operation Tips:
• Cut your grass before operation and fertilize after the
operation.
• Adjust the depth of the cutting tool in accordance with
the height of the grass and weather.
• Avoid operating on wet grass. It tends to stick on the
discharge port and other parts of the machine. It may
also cause slip and fall.
• Do not move too fast. Push the machine slowly.
Otherwise discharge port may become clogged and the
motor may overloaded.
• Operate along a line as straight as possible.
• Make slightly overlapping scarified lines. It will maintain
even and smooth surface.
• When a flower bed is included in the operating area,
make a circle or two around the flower bed.
• Be especially careful when turning the machine.
• Do not stay in one position. It damages the grass.
Tips for scarifying:
• Always take the weather into account. Warm, sunny
and wet weather is good for scarifying because the
lawn can recover healthily. On the other hand, avoid
cold, heat, dry weather.
• During spring season scarify the lawn.
• If summer is wet, scarify the lawn in early autumn.
• Refrain from scarifying during period of extremely hot
weather.
• If summer is very dry, do not scarify in autumn.
Tips for raking:
• Plenty amount of air is needed for the area around the
roots of the lawn in order to maintain healthy growth in
spring season.
• It is recommended performing aeration operation on the
lawn every 4 – 6 weeks in accordance with the state of
the lawn.
Do NOT use for raking
operation.
