Working Advice

Raking/Verticutting
UniversalRake 900:
In case of overload, the speed of the motor drops and the
motor sound changes. In this case, stop, release the start/
stop lever and adjust to a higher working height. Failure to
do so could damage the machine.
UniversalVerticut 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, switch the product off.
The safety cut out is only reset when the start/stop lever is
released.
Pull the mains plug, remove any blockages and wait one
minute before restarting the product so that the safety cut
out can reset itself.
Always wear gardening gloves when handling or work-
u
ing near the sharp tines/blades.

Bosch Power Tools
Place the product on the
edge of the lawn, as close to
the mains socket as pos-
sible. Work away from the
mains socket.
Position the cable to oppos-
ite side (already raked/ver-
ticut lawn) at the end of
each turn.
When raking/verticutting do
not overload the motor.
Note: When waiting for a reset of the safety cut out and actu-
ating the start/stop lever too early with the product plugged
into the socket outlet, the reset time of the safety cut out will
increase.
If the product cuts out again, increase the working height or
postpone use until conditions improve. Please refer to the
Trouble Shooting Chart" and "Raking/Verticutting Tips".
Raking/Verticutting Tips
Optimum conditions for raking/verticutting are when the
grass is short and slightly moist. Raking or verticutting the
lawn when the soil is very soft or hard can damage it and
cause the product to collect poorly.
– Kill moss with a commercially-available moss killer before
raking/verticutting.
– Start the product at the highest working height and lower
it as required.
– Rake/Verticut the lawn in the one direction, then proceed
at right angles a week later until the whole lawn has been
completed.
– Depending on the condition of the lawn, raking/verticut-
ting moss and dead plant parts can lead to ragged and
bare patches.
Note: In conditions with excessive tree debris (e. g. leaves,
twigs, etc.), first clear the surface by using the product with
the working height set to 3 or 4.
For best results mow the lawn before reseeding. Promote
the spread of grass into bare and weak areas with good qual-
ity lawn seed after raking/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 au-
tumn.
Lawns can also be maintained by raking/verticutting on a
higher setting after every six cuts.
Corrective Measure
Turn power on
Use other socket
Inspect cable, replace if damaged
If fuse blows continuously, please check your
electricity supply system or contact Bosch cus-
tomer service agent
Check underneath the garden product and clear
out as necessary (always wear protective gloves)
