standstill within three seconds.
After release, the bar must always return to the position shown in the "component
description" diagram.
If this is not the case, it must be checked immediately by an authorised workshop.
Risk of injury!
If the blade run-on time is longer, stop using the equipment and take it to an authorised
workshop.
Measuring run-on time
After the electric motor has been started, the blade rotates and a wind-like noise can be
heard.
The run-on time corresponds to the duration of the wind-like noise after the electric
motor has been switched off, it can be measured using a stopwatch.
Machine safety and protective devices must not be manipulated or disabled.
The perfect function of the motor drive control bar must also be checked before every
mowing job. When the motor drive control bar is released, the machine must come to a
standstill immediately. If this is not the case, it must be checked immediately by an
authorised workshop.
Make sure that all protective devices have been attached properly and are not
damaged.
Check the upper part of the bar (insulation) for damage. If the casing should be
damaged, contact the nearest authorised workshop without delay, since otherwise
injuries (electric shock) can occur through touching the live parts.
To avoid risk, check the condition and firm attachment of the blade before every
mowing job. The blade attachment screw must always be tightened by an authorised
workshop since an insulation protection test always has to be carried out after repairs
and maintenance work on insulation parts (e.g. blade screw) in accordance with the
applicable standard DIN EN 60335. A worn or damaged blade must always be
replaced. (refer here to the chapter "Cutter blade care")
In addition, check the fan, blade coupling and fan housing every 10 operating hours for
wear and a tight fit. Also check equipment screws and nuts for a firm fit and tighten if
necessary.
If the mower mechanism becomes blocked e.g. by colliding with an obstacle, have an
authorised workshop check whether any parts of the mower are damaged or deformed.
Always have any necessary repairs done by an authorised workshop too.
If the machine starts to vibrate unusually heavily or to make unusual noises, please
have it checked immediately by an authorised workshop.
Time restrictions
In Germany, the set hours for operating lawnmowers are regulated in the "32nd
Ordinance implementing the Federal Emissions Protection Act (32nd BImSch-V)".
In addition, there may be regional restrictions (e.g. to protect midday peace), which can
be issued by the respective local authority.
Tips on caring for your lawn
Mowing (Illustration M )
WARNING
Remove any objects (stones, wood, branches, etc.) from the lawn before each
cut; but still watch out for objects lying around during the mowing process.
Ask your dealer about lawn care instructions. Information and instructions about
mowing can also be found on the manufacturer website.
Mulching
Your lawn mower can also be equipped with a mulching kit. The respective conversion
kit to a mulching system is available as an accessory from professional dealerships
(see genuine spare parts and accessories for the conversion kit order no.).
The mulching kit also includes tips and information about mulching. You will also find
information about mulching on the manufacturer website.
WARNING
Always have an authorised workshop convert the mower into a mulching system,
since an insulation protection test always has to be carried out after repairs or
maintenance work on insulation parts (e.g. blade screw) in accordance with the
applicable standard DIN EN 60335.
In addition, a wrongly assembled cutting blade coupling can allow the cutter bar
to become loose, which can lead to serious injuries.
If the grass should happen to be too high for mulching, the mulching mower can be
converted for mowing with a grass collecting bag in no time.
Converting the machine to rear ejection (Illustration U2 + S1 )
– Stop the engine.
– Lift the ejection flap.
– Remove the mulching plug from the channel U2 .
– Hook the grass collecting bag in the bracket provided on the mower housing S1 .
The mulching blade system does not have to be converted! The capacity of the
collecting bag can be reduced under difficult mowing conditions (e.g. wet grass).
For the equipment to be used as a mulching machine again, the mulching plug must be
installed again. To do this, remove the grass collecting bag, insert the mulching plug
into the ejector channel and close the ejector flap.
Clean the ejector channel first.
16 SERVICE INTERVALS
IMPORTANT
Avoid damage! Under extreme or unusual conditions, shorter servicing intervals
than the ones specified below may be necessary. If you establish any problems,
please contact an authorised workshop.
Carry out routine servicing on the machine in line with the following servicing intervals.
Work must be carried out at the following servicing intervals in addition to the
maintenance work listed in these operating instructions.
Before initial use
• Check all screw connections for a tight fit.
• Check the cutting blade screw and have an authorised workshop tighten it if
necessary.
• Check whether the safety control bar for the engine brake is working perfectly.
• Check that all protective devices have been attached properly and are not
damaged.
Before every operation
• Check the lawn area and remove any objects.
• Check the area of the boundary wires (if an automatic mower is being used for
lawn care).
• Check the condition and firm fit of the blade, if necessary have an authorised
workshop tighten the blade screw.
• Check whether the safety control bar for the engine brake is working perfectly.
• Check that all protective devices have been attached properly and are not
damaged.
• Check grass collecting equipment for wear or loss of functionality.
• Check the upper part of the bar (insulation) for damage.
• Check the connection cable for damage and ageing.
Every 10 operating hours
• Check all screw connections for a tight fit.
• Check the fan, blade coupling and fan housing regularly for wear and a tight fit.
After every operation
• Clean the mower.
• Check the blade for damage and wear.
Every 15-20 operating hours or annually
• Lubricate the wheel bearings.
During annual servicing
• Clean the gearbox and the area under the belt cover.
• Check the drive throttle cable and adjust it if necessary.
17 CARE AND SERVICING OF YOUR LAWNMOWER
Regular care is the best way to guarantee a long service life and problem-free
operation. Insufficient equipment maintenance will lead to safety-related faults!
Only use original spare parts because only those guarantee safety and quality!
Safety instruction!

Cleaning (Illustration O )
Remove dirt and grass residue immediately after finishing mowing. Place the mower on
its side and use a brush or cloth to clean.
ATTENTION
Do not put your fingers into the openings of the fan housing and hold onto the
fan. If the blade bar is rotated during cleaning, there is a risk that your fingers
may become caught between the fan and the fan housing!
IMPORTANT
Never spray the mower with water. This may damage the electrical systems.
