Note: Please observe the order number of your machine. The trade names of individual machines can vary.
Inrush currents cause short-time voltage drops. Under unfavourable power supply conditions, other equipment may be affected. If the system impedance of the power supply is lower than 0.36 Ohm, disturbances are unlikely to occur.
Intended Use
This product is intended for domestic lawn mowing.
Introduction
This manual gives instructions on the correct assembly and safe use of your machine. It is important
that you read these instructions carefully.
When fully assembled the machine weighs approximately between 11 and 13.5 kg. If necessary, obtain

For Your Safety
Warning! Switch off, remove plug from mains
before adjusting, cleaning or if cable is cut,
damaged or entangled.
The blades continue to rotate for a few seconds after the machine is switched off.
Caution - do not touch rotating blades.
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 service agent 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 operating your product, only the following cable dimensions should be used:
- 1.0 mm2: max length 40 m
- 1.5 mm2: max length 60 m
- 2.5 mm2: max length 100 m
It is recommended for increased electrical safety to
use a Residual Current Device (RCD) with a tripping
current of not more than 30 mA. Always check your
RCD every time you use it.
If the supply cord is damaged, it must be replaced by
a Bosch Service Centre.
B For products not sold in GB:
WARNING: For safety, it is essential that the mains
plug 5 attached to the machine is fitted to the power
supply cable 15.
The couplings of connection leads must be protected against splashes and the coupling sockets on
the leads must be made of rubber or coated with rubber.
Fixing means for the connection leads must be used.
The connection lead must be inspected for signs of
damage at regular intervals and may only be used if
in perfect condition.
Products sold in GB only: Your mower 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 by an authorized customer sercive agent.
The severed plug must be disposed of to avoid a
possible shock hazard and should never be inserted
into a 13 A socket elsewhere.
Assembly
A Handle assembly
➊ Insert the handle bottom 8 into the holes provided
and
➋ secure with the screws.
Note: The handle top 3 is height adjustable. Fix handles in desired position I or II.
Snap together the grassbox
C ROTAK 34/36
Snap the grassbox top on the grassbox bottom by
pushing all the “snap fits” together around the edges
starting at rear and working towards the front.
D ROTAK 40/43
➊ Snap the grassbox bottom halves together by
pushing all the “snap fits” together around the edges
starting at rear and working towards the front.
➋ Snap together both top and bottom half of the
grassbox.
Ensure the cables are not trapped when folding/unfolding top handles. Do not drop the handles.
E
Fitting
Lift the deflector guard 7 and hold up, fit the grassbox 6.
Removing/Emptying
Lift the deflector guard 7 and hold up. Remove
grassbox 6.
For non grass collection the mower can be used
without the grassbox 6 in position, with the deflector
guard 7 in the down position.
Adjusting the Cutting Height
Stop, release switch lever and wait until
the motor stops before adjusting height.
The blades continue to rotate after the machine is switched off, a rotating blade can
cause injury.
Caution: Do not touch rotating blades.
For the first cutting of the season, a high cutting adjustment should be selected.
F The lawnmower can be set to 10 cutting heights
between 20 mm and 70 mm. For this purpose, press
the height of cut lever 12 inwards then lift or push
down the mower until required height is selected.
G
➌ Attach
the handle top 3 with the bolts and wing
nuts 14 to the handle bottom 8.
Note: Ensure that the cable clips supplied are used
to fix the cable to the handle.
B Attach cable to cable restraint 4 ensuring that
sufficient cable slack is available.

Starting and Stopping
The blade continues to rotate for a few
seconds after the machine is switched off.
Allow the motor/blade to stop rotating before switching “on” again.
Do not rapidly switch off and on.
To aid starting tilt mower to side.

Maintenance
the
handle.
Release the safety button 2.
Stopping:
Release the switch lever 1.
The mower is fitted with a blade brake. This safety
feature stops the blade from rotating in a few seconds. You may notice a slight smell during the first
few operations of the brake (on releasing the On/Off
switch).This is entirely normal and will cause no
damage to your machine.
The blade maybe stiff to turn by hand while the machine is not in operation, this is due the brake.
Always wear gardening gloves when handling or working near the sharp blade.
Mowing
I Place the lawnmower on the edge of the lawn, as
close to the power point as possible. Work away
from the power point. Then at right angles.
Position the cable to opposite side (already cut) at
the end of each turn.
When mowing 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 mowing, 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. When this occurs
stop, remove the plug from the power supply.
The safety cut out will only reset when the switch
lever 1 is released. Clear any obstruction and
wait for a few minutes for the safety cut out to reset before continuing to use the mower. At this
time do not operate the switch lever 1 as this will
prolong the reset time of the safety cut out. If the
mower cuts out again increase the height of cut
to reduce the load on the motor.
H The grass combs 11 allow a very close cut to the
wall or edge. Beware of running combs into objects
while cutting close to walls/edges.
F 016 L70 635 • 09.11
Stop, remove plug from the power supply
and remove the grassbox.
Always wear gardening gloves when handling or working near the sharp blade.
Note: To ensure long and reliable service, carry out
the following maintenance regularly.
Regularly check for obvious defects such as loose,
dislodged or damaged blade, loose fixings, and
worn or damaged components.
Check that covers and guards are undamaged and
correctly fitted. Carry out necessary maintenance or
repairs before using.
If the mower should happen to fail despite the care
taken in manufacture and testing, repair should be
carried out by an authorised customer service agent
for Bosch garden products.
For all correspondence and spare parts orders, always include the 10-digit part number (typ) from the
nameplate of the machine!
Blade Maintenance
Stop, remove plug from the power supply
and remove the grassbox.
Turn the machine on its right side and inspect the
blade; if blunt or damaged, replace.
Use the following procedure to remove and replace
the blade.
Hold the blade 17 using gardening gloves (not provided) use a spanner (not provided) to remove the
blade bolt 16, blade washer 18 (Rotak 34/36 only),
bevel washer 20 and blade. Fit the bevel washer,
blade, blade washer and the blade bolt. Ensure that
the blade is the correct way up (so that this
symbol can be seen located as in figure J) and tighten
the bolt firmly.
In the event of a blade becoming difficult to remove
or fit, insert a screwdriver into hole 21 to lock the
drive. Ensure the screwdriver is removed before attempting to turn the machine on.
Do not lubricate blade or blade bolt during
refitting!
After Mowing/Storage
Clean the exterior of the machine thoroughly using a
soft brush and cloth. Do not use water, solvents or
polishes. Remove all grass and debris, especially
from the ventilation slots 9.
Using a soft brush clean the grass comb 11 removing any grass and debris.
Turn the machine on its side and clean the blade
area. If grass cuttings are compacted in the blade
area, remove with a wooden or plastic implement.
Always wear gardening gloves when handling or working near the sharp blade.
Store the machine in a dry place. Do not place other
objects on top of the machine.
To aid storage loosen the wing nuts 14 and fold the
handles.
Ensure cables are not trapped when folding/
unfolding top handles, do not drop the handles.
