Risk of injury and physical damage !
Do not clean Aerator under running water (particularly under high pressure ).
Do not use hard or pointed objects for cleaning the Aerator.
E
Remove grass and deposits from wheels, aerator cylinder and hosing.
Adjusting for wear:
①
F
The Aerator is subject to wear in use due to the
way in which it works . The more intensively the
Aerator is used , the greater the wear on the
knives.
Hard or very dry ground accelerates wear as
does excessive use of the Aerator
If the results of your
work with the Aerator
become increasingly worse due to knife wear,the
aerator cylinder can be adjusted twice.
Note: Wear adjustment is not used for height adjustment. Adjustment of the aerator
cylinder without visible wear can cause damage to the aerator cylinder or overload the
motor.
The aerator cylinder
has variable height
adjustment positions. When you want to move
the aerator when not in use, you should rotate
the adjustment button ①to the “high” position.
Transport position:
Rotate the adjustment button ①to the
“high”position gently away from the housing and
move to the position required.

7. Scarifier Operation
It is recommended to start scarification/aeration at a point close to the power supply and
to work your way away from the supply. Proceed at a right angle from the power supply
and place the power cable to the side which has already been scarified (E).
Warning ：When scarifying do
not allow the motor to labour
particularly in heavy conditions.
When the motor labours the speed of the
motor drops and you will hear a change in
the motor sound, when this occurs stop
scarifying, release the switch lever and raise
the height of cut. Failure to do so could
damage the machine.
NOTE: the motor is protected by a safety cut
out which is activated when the blade
becomes jammed or if the motor is
overloaded.
Safety Overload:
When this occurs, stop the machine and
remove the plug from the power supply. The safety cut out will only reset when the switch
lever (10) is released. Clear any obstruction and wait for a few minutes for the safety cut
out to reset before continuing to operate. At this time do not operate the switch lever (10)
as this will prolong the reset time of the safety cut out. If the tool cuts out again, increase
the height of cut to reduce the load on the motor.
