Working Advice
Raking/Verticutting
Place the
ALR 900/AVR1100 on
the edge of the lawn, as
close to the power point
as possible. Work away
from the power point.
Position the cable to op-
posite side (already
raked/verticut lawn) at
the end of each turn.
When raking/verticut-
ting do not allow the
motor to labour.
ALR 900:
When the motor labours the speed of the motor
drops and you will hear a change in the motor
sound. When this occurs, stop raking, release
switch lever 2 and raise the height of cut. Failure
to do so could damage the machine.
AVR 1100:
The motor is protected by a safety cut out which
is activated when the blades become jammed,
clogged or if the motor is overloaded. When this
occurs, stop using the machine.
The safety cut out will only reset if the switch le-
ver 2 is released.
Remove the plug from the power supply, clear
any obstruction and wait a minute for the safety
cut out to reset before continuing to use the ma-
chine.
f Always wear gardening gloves when han-
dling or working near the sharp tines/blade.
Note: When waiting for a reset, operating switch
lever 2 too early with the machine plugged into
the supply will prolong the reset time of the safe-
ty cut out.
If the machine cuts out again, increase the height
of cut or postpone use until conditions improve.
Please refer to “trouble shooting table” and “rak-
ing/verticutting tips”.
Raking/Verticutting Tips
Optimum conditions for raking/verticutting are
when the grass is short and slightly damp. Rak-
ing/Verticutting when the ground is very soft or
hard it will may damage the lawn and will result
in poor collection.
– Kill moss with a proprietary moss killer before
raking/verticutting.
– Start the ALR 900/AVR 1100 at the highest
raking/verticutting position and lower as nec-
essary.
– Rake/Verticut the lawn in the one direction,
then proceed at right angles a week later until
the whole lawn has been completed.
– The action of removing moss and debris dur-
ing raking/verticutting may reveal ragged and
bare patches depending on lawn conditions.
Note: In conditions with excessive tree debris
(e. g. leaves, twigs, etc.) first clear the surface by
using the machine with a height of cut setting of
either 3 or 4.
For best results mow the lawn before reseeding.
Promote the spread of grass into bare and weak
areas with good quality lawn seed after rak-
ing/verticutting. Allow fresh grass seed to root
and establish before fertilising, where necessary
water to prevent fresh seeds drying out.
Ideal times for raking/verticutting are spring and
late autumn.
Also lawn can be maintained by raking/verticut-
ting on a higher setting after every six cuts.
