Electrical Safety
Your machine is double insulated for safety and
requires no earth connection. The operating
voltage is 230 V AC, 50 Hz (for non-EU countries
220 V, 240 V as applicable). Only use approved
extension cables. Contact your Bosch Service
Centre for details.
Extension cords/leads should only be used if
they comply with H05VV-F, H05RN-F types or
IEC type design (60227 IEC 53, 60245 IEC 57).
If you want to use an extension cable when op-
erating your product, only the following cable di-
mensions should be used:
–1.0mm
2: max. length 40 m
– 1.5 mm2: max. length 60 m
– 2.5 mm2: max. length 100 m
Note: If an extension cable is used it must be
earthed and connected through the plug to the
earth cable of your supply network in accord-
ance with prescribed safety regulations.
If in doubt contact a qualified electrician or the
nearest Bosch Service Centre.
WARNING! Inadequate extension cables can
be dangerous. Extension cable, plug and sock-
et must be of watertight construction and in-
tended for outdoor use.
Cable connections should be kept dry and off
ground.
It is recommended for increased electrical safe-
ty to use a Residual Current Device (RCD) with
a tripping current of not more than 30 mA. Al-
ways check your RCD every time you use it.
If the supply cord is damaged, it must be re-
placed by a Bosch Service Centre.
Products sold in GB only: Your product is fitted
with an approved 13 A (BS 1363/A) electric plug
and is protected by a 13 A fuse (ASTA Approved
to BS 1362).
If the fitted plug is not suitable for your socket
outlets, it should be cut off and an appropriate
plug fitted in its place.
The severed plug must be disposed of to avoid a
possible shock hazard and should never be in-
serted into a 13 A socket elsewhere.
Assembly
fEnsure the cables are not trapped when
folding/unfolding top/bottom handles. Do
not drop the handles.
Assembly of Product
Fix the handle bottom 6to the body of the ma-
chine with two bolts and wing nuts.
Attach the handle top 1with the bolts and the
wing nuts to the handle bottom 6.
Note: Ensure that the cable clips supplied are

of the grassbox bottom and close the two halves
together.
Fasten the two red clips (one per side).
Attach/remove the grassbox 7as shown.
Adjusting the Cutting Height
Pull the lever top 9towards the wheel and then
rotate it to the front or rear of the machine to
achieve the desired cutting height.
Repeat this for both sides of the product.
Make sure that both levers 9are set to the same
position.

Working Advice
Raking/Verticutting
Place the ALR 900/
AVR 1100 on the edge
of the lawn, as close to
the power point as
possible. Work away
from the power point.
Position the cable to
opposite side (already
raked/verticut lawn) at
the end of each turn.
When raking/verticutting do not allow the mo-
tor 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 2and raise the height of cut. Fail-
ure 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 2is 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.
fAlways wear gardening gloves when han-
dling or working near the sharp tines/blade.
Note: When waiting for a reset, operating switch
lever 2too early with the machine plugged into
the supply will prolong the reset time of the
safety cut out.
If the machine cuts out again, increase the
height of cut or postpone use until conditions
improve. Please refer to “trouble shooting ta-
ble” and “raking/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 be-
fore raking/verticutting.
– Start the ALR 900/AVR 1100 at the highest
raking/verticutting position and lower as
necessary.
– Rake/Verticut the lawn in the one direction,
then proceed at right angles a week later un-
til 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 neces-
sary 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.
