Important!
When using the equipment, safety precautions
must be observed to avoid injuries and damage.
Please read the complete operating instructions
and safety regulations with due care. Keep this
manual in a safe place, so that the information is
available at all times. If you give the equipment
to any other person, hand over these operating
instructions and safety regulations as well. We
cannot accept any liability for damage or
accidents which arise due to a failure to follow
these instructions and the safety instructions.
1. Safety instructions for
hand-operated lawn mowers
Note
1. Read the directions with due care. Familiarize
yourself with the settings and proper operation
of the machine.
2. Never allow children or other persons who are
not familiar with the operating instructions to
use the mower.
3. Never mow in the direct vicinity of persons
- especially children - or animals. Always keep
in mind that the operator is responsible for
accidents involving other persons and/or their
property.
Preliminary measures
1. Always wear sturdy, non-slip footwear and long
trousers when mowing. Never mow barefoot or
in sandals.
2. Check the grounds on which the machine will
be used and remove all objects that could be
caught up and violently flung out of the chute.
3. Warning: Petrol is highly flammable! Therefore:
- Only store petrol in containers designed to
hold petroleum-based liquids.
- Only refuel out in the open and do not smoke
during the refueling process.
- Always refuel the lawn mower before starting
the engine. Always ensure that the fuel tank
cap is closed when the engine is running and
when the mower is hot; also do not refuel.
- If petrol has overflowed, do not under any
circumstances attempt to start the engine.
Instead, remove the machine from the
affected area. Avoid starting the engine until
the petrol fumes have completely evaporated.
- For safety reasons, the petrol tank and other
tank closures must be replaced if they are
damaged.
4. Replace defective exhausts.
5. Before using the mower, visually-inspect it to
ensure that the blade, mounting bolts and the
entire cutting apparatus are in good working
order (i.e. not worn out or damaged). To
prevent any imbalance, replace worn out or
damaged blades and mounting bolts as a set
only (if applicable).

3. Proper operation
The petrol lawn mower is intended for private use
i.e. for use in home and gardening environments.
Private use of the lawn mower refers an annual
operating time generally not exceeding that of
50 hours, during which time the machine is
primarily used to maintain small-scale, residential
lawns and home/hobby gardens. Public facilities,
sporting halls, and agricultural/forestry applications
are excluded.
Please note that our equipment has not
been designed for use in commercial, trade
or industrial applications. Our warranty will
be voided if the machine is used in
commercial, trade or industrial businesses
or for equivalent purposes.
The operating instructions as supplied by the
manufacturer must be kept and referred to in
order to ensure that the lawn mower is properly
used and maintained. The instructions contain
valuable information on operating, maintenance
and servicing conditions.
Important! Due to the high risk of bodily injury to
the user, the lawn mower may not be used to trim
bushes, hedges or shrubs, to cut scaling
vegetation, planted roofs, or balcony-grown
grass, to clean (suck up) dirt and debris off
walkways, or to chop up tree or hedge clippings.
Moreover, the lawn mower may not be used as a
power cultivator to level out high areas such as
molehills.
For safety reasons, the lawn mower may not be
used as a drive unit for other work tools or toolkits
of any kind.

Assembly
1. Take the mower and attachment parts out
of the packaging and check that all parts are
present (Fig. 2).
2. Affix the lower push bar (Fig. 3a/Item 5) to
the mower housing and set the desired
working height. 3 different working heights are
available. Each peg on the lower push bar
can be inserted into a hole situated directly
opposite to it, on the mower housing, for
example A-A (Fig. 3). The lower push bar must
be equally adjusted on both sides. Now affix
the cover (Fig. 3a/Item 22) and attach the
push bar (5) using the square head screws (14)
and the star knobs (17) as shown in Figure 3a.
3. Fasten the top push bar to the bottom push
bar using a lever cam screw (Fig. 3b/Item 15)
and a star knob (Fig. 3b/Item 17) on each
side. Make sure that the lobes of the lever
cam screws are folded towards the inside so
that the high speed clamping function
remains operational.
4. Insert the grip of the starter cord (Fig. 3c/
Item 4) into the hook provided for that purpose
as shown in Figure 3c.
5. Fasten the cords to the push bar with the
supplied cable ties (Fig. 3d/Item. 12).
6. Lift the ejector flap (Fig. 4 / Item 7) with one
hand and hook in the grass bag as shown in
Figure 4.
5.2 Setting the cutting height
Important! Adjust the cutting height only when
the engine is switched off and the plug boot
has been pulled.
- Before you begin to mow, check to ensure
that the blade is not blunt and that none of
the fasteners are damaged. To prevent any
imbalance, replace blunt and/or damaged
blades as a set only (if applicable). To carry
out this check, first switch off the engine and
pull the spark plug boot.
- The cutting height is centrally adjusted with
the cutting height adjustor lever (Fig. 7/Item 8).
Up to 5 different cutting heights can be
selected.
- Pull the adjustor lever out and select the
desired cutting height. The lever snaps into the
desired position.
6. Operation
Note: For detailed information on the engine
& oil, refer to the enclosed manual from
Briggs & Stratton.
Important. The engine does not come with oil in
it. Therefore, be sure to add oil before starting the
engine. The oil level in the engine must be
checked each time before mowing (see the
Briggs & Stratton manual). You will also need to fill
the fuel tank with petrol, as this is also not supplied
upon delivery.
In order to avoid any unintentional start-ups of the
lawn mower, it comes equipped with an engine
brake (Fig. 5a/Item 1) which must be pulled back
before the engine can be started. When the
engine control lever is released it must return to its
initial position, at which point the engine
automatically switches off.
You can control the rotation speed of the blade
using the speed lever (Fig. 6).
Before you start mowing, you should run through
this operation several times in order to ensure that
the machine is working properly.
Whenever you need to perform any kind of
adjustment and/or repair work on your lawn
mower, wait until the blade has come to a
complete stop.
Always switch off the engine before carrying out
any adjustments, maintenance or repairs.
Note:
1. Engine brake (Fig. 5a/Item 1): Use the lever to
stop the engine. When you release the lever the
engine and the blade stop automatically. To
mow, hold the lever in the working position (Fig.
5b). Before you start to mow, check the start/stop
lever several times to be sure that it is working
properly. Ensure that the tension cable can be
smoothly operated (i.e. is not catching or kinked in
any way).

2. Speed lever (Fig. 6): Move this lever in order to
increase or decrease the engine speed.
(Tortoise = Slow / Hare = = Fast).
3. Drive lever (clutch lever) (Fig. 5a/Item 18): If you
press this (Fig. 5c) the clutch for the drive will be
closed and the lawnmower will start to move with
the motor running. Release the drive lever in good
time to stop the moving lawnmower. Practice
starting and stopping before you use the mower
for the first time until you are familiar with
controlling the mower.
4. Caution: The blade begins to rotate as soon
as the engine is started.
Important: Before you start the engine, move the
motor brake several times to be sure that the stop
cable is properly working. Note: The engine is
factory set to a speed that is optimal for cutting
and blowing grass into the collection bag and is
designed to provide many years of use.
5. Check the oil level.
6. Fill the tank with petrol when it is empty, using a
funnel and measuring vessel. Make sure that the
petrol is clean.
Note: Use only unleaded petrol as fuel.
Warning: Never use more than one safety petrol
can. Do not smoke when refueling. Switch off the
engine before refueling and allow the engine to
cool down for a few minutes.
To Start the Engine
7. Ensure that the ignition cable is connected to
the spark plug.
8. Press the red primer button 5 times (Fig. 10).
9. Move the speed lever to the Hare
setting (Fig. 6).
10. Stand behind the mower. Place one hand on
the engine start/stop lever and pull the bars
together (Fig. 5a Fig. 5b). Place the other hand
on the starter handle.
11. Start the engine using the reversing starter
(Fig.3c/Item 4). To do this pull the handle
approx.10 – 15 cm (until you feel a resistance)
and then start the engine with a sharp pull. If the
engine does not start, pull the handle again. This
could take up to 10 pulls.
Important! Never allow the starter cord to
snap back.
Note: In cold weather, it may be necessary to
repeat the starting process several times.
12. When the engine is at working temperature it
can be started in the Tortoise setting (Fig. 6).
To start the mower moving forward
Once the engine is running, operate the engine
drive; by pulling the Drive lever towards the top
push bar (Fig. 5c). Always walk behind the
lawnmower whist the drive is working.
To stop the mower moving forward
Release the Drive lever away from the top push
bar (Fig. 5b). The engine will still be running & the
blade will still be rotating.
To stop the engine
(Always try to release the Drive lever, before
stopping the engine). Release the engine start/
stop lever (Fig. 5a). The Engine will stop running &
the blade will stop rotating.
Mulching
In the mulching mode the cuttings are shredded
in the enclosed mower housing and then spread
back onto the lawn. It is not necessary to gather
and dispose of the grass.
Important: Mulching is only possible if the lawn is
relatively short. Optimum results can be achieved
only with a mulching blade (available as an
accessory).
To use the mulching function, remove the grass
collection bag, slide the mulching adaptor into
the ejector opening (Fig. 5d/Item 20) and close
the ejector opening.
Side ejector
You should fit the mulching adaptor (Fig. 5d / Item
21) in order to use the side ejector. Connect the
side ejector adaptor (Fig. 5e/Item 18) as shown in
Figure 5e.
6.1 Before mowing
Important information
1. Make sure that you are properly dressed when
mowing. Wear sturdy, non-slip footwear; do not
wear sandals or tennis shoes.
2. Inspect the blade. A blade that is bent or
damaged in any other way must be immediately
exchanged for a genuine Einhell replacement
blade.

the open. Use a filling funnel and a measuring
jug. Wipe off any spilled petrol.
4. Read and follow the instructions in the
operating manual as well as the information
regarding the engine and accessory equipment.
Store the manual in a place where it can be
readily accessed by other users of the machine.
5. Exhaust gas is dangerous. Only start the engine
out in the open.
6. Make sure that all the guards are fitted and
that they are in good working order.
7. The machine should only be operated by
persons who are well informed with the way it
works, and who are in reasonably good physical
condition.
8. It can be dangerous to mow the grass when it
is wet. Try to ensure that you only mow the grass
when it is dry.
9. Advise children and others to keep well away
from the lawn mower.
10. Never mow the grass in poor visibility.
11. Remove all loose objects from the lawn
before you start mowing the grass.
6.2 Tips for proper mowing
Important! Never open the chute flap when the
grass collection bag has been detached (to be
emptied) and the engine is still running. The
rotating blade can cause serious injuries!
Always carefully fasten the chute flap and
collection bag. Switch off the engine before
emptying the collection bag.
Always ensure that a safe distance (provided by
the length of the long handles) is maintained
between the user and the mower housing. Be
especially careful when mowing and changing
direction on slopes and inclines. Maintain a solid
footing and wear sturdy, non-slip footwear and
long trousers. Always mow along the incline (not
up and down).
For safety reasons, the lawn mower may not be
used to mow inclines whose gradient exceeds 15
degrees. Use special caution when backing up
and pulling the lawn mower. Tripping hazard!
6.3 Mowing
Only use a sharp blade that is in good condition.
This will prevent the grass blades from fraying and
the lawn from turning yellow.
Try to mow in straight lines for a nice, clean look in
in so doing, the mowing swaths should always
overlap each other by a few centimeters in order
to avoid bare strips.
Keep the underside of the mower housing clean
and remove grass build-up. Deposits not only
make it more difficult to start the mower; they
decrease the quality of the cut and make it
harder for the machine to bag the grass. Always
mow along inclines (not up and down). Slightly
turning the front wheels up the hill while mowing
will assist the mower in producing a straight line.
Select the cutting height according to the length
of the grass. If the lawn has grown quite a bit,
mow over it several times so that no more than 4
cm of grass are cut at one time.
Switch off the engine before inspecting the
blade. Keep in mind that the blade continues
to rotate for a few seconds after the engine
has been switched off. Never attempt to
manually stop the blade.
Regularly check to see if the blade is securely
attached, is in good condition and is sharp. If the
contrary is the case, sharpen the blade or
replace it. In the event that the blade strikes an
object, immediately switch off the lawn mower
and wait for the blade to come to a complete
stop. Then inspect the condition of the blade and
the blade mount. Replace any parts that are
damaged.
Tips for proper mowing:
1. Pay attention to ensure that you do not run into
or over anything that could damage the mower.
The lawn mower could be damaged and/or the
machine could inflict bodily injury.
2. A hot engine, exhaust or drive unit can burn the
skin if touched. Thus, do not touch these parts
unless the mower has been switched off for some
time and you know that they have cooled down!
3. Use extra caution when mowing on inclines
and steep grades.
4. Do not use the mower if the daylight or artificial
light levels are insufficient .
5. Check the mower, the blade and other parts if

Helpline No. UK 0151 649 1500 / IRE 189 094 6244
Helpline No. UK 0151 649 1500 / IRE 189 094 6244
14
they have struck a foreign object or if the
machine vibrates more than usual.
6. Do not make any adjustments or repairs until
the engine has been switched off. Pull the plug
boot off the spark plug.
7. Pay special attention if you are mowing directly
next to a street or are close by one (traffic). Always
keep the grass chute pointed away from the
street.
8. Avoid mowing in places where the wheels
have trouble gripping or mowing is unsafe in any
other way. Before you back up, ensure that
nobody is standing behind you (especially little
children and pets who are more difficult to see).
9. When mowing over thick, high grass, select the
highest cutting level and mow at a slower speed.
Before you remove any grass or blockages of any
kind, switch off the engine and pull the plug boot.
10. Never remove any safety-related parts.
11. Never fill the engine with petrol when it is hot or
is running.
6.4 Emptying the collection bag
As soon as grass clippings start to trail the lawn
mower, it is time to empty the collection bag.
Important! Before taking off the grass collection
bag, switch off the engine and wait until the
blade has come to a stop.
To take off the grass collection bag, use one
hand to lift up the chute flap and the other to
grab onto the grass collection bag handle (Fig.
4). Remove the grass collection bag. For safety
reasons, the chute flap automatically falls
down after removing the grass collection bag
and closes off the rear chute opening. If any
grass remains in the opening, it will be easier to
restart the engine if you pull the mower back
approx. 1 metre.
Do not use your hands or feet to remove
clippings in or on the mower housing, but instead
use suitable tools such as a brush or a hand
broom. Ensure that both the engine and the
blade are stopped before attempting to remove
clippings and debris.
In order to ensure that the majority of grass
clippings are picked up, the inside of both the
catch bag and especially the air grill must be
cleaned after each use.
Re-attach the catch bag only when the engine is
switched off and the blade is stopped.
Using one hand, lift up the chute flap, while
grabbing onto the grass collection bag handle
with the other. Hook on the grass collection bag
from the top. (see Fig. 4).
6.5 After mowing
1. Allow the engine to cool before you put the
lawn mower in an enclosed area.
2. Remove grass, foliage, grease and oil before
storing the mower. Do not place any objects on
top of the mower.
3. Check all the screws and nuts once more
before you start to use the lawn mower again.
Tighten any loose screws.
4. Also be sure to empty the grass collection bag.
5. Pull the spark plug boot to prevent
unauthorized use.
6. Ensure that you do not park the mower next to
any source of danger. Petrol fumes can lead to
explosions.
7. Only original parts or parts approved by the
manufacturer may be used for repairs (see c).
8. If the lawn mower is not going to be used for
an extended period, empty the petrol tank using
a petrol suction pump.
9. Tell your children not to use the mower.
It is not a toy.
10. Never place petrol near an ignition source.
Always use a can that is approved to store petrol.
Keep petrol away from children.
11. Oil and maintain the machine.
7. Cleaning, maintenance, storage,
transport and ordering of spare parts
Important: The enclosed engine manual from
Briggs & Stratton provides maintenance
information and maintenance interval
information on the engine.
Important:
Never work on or touch conducting parts on the

ignition unit with the engine running. Always pull
the spark plug boot from the spark plug before
starting any cleaning or maintenance. Never
perform any work on the machine while it is
running. Any work not described in these
Operating Instructions must be performed by an
authorized service workshop only.
7.1 Cleaning
After each use, the mower should be thoroughly
cleaned (especially the underside and blade
receptacle).
Note: Before you tilt the lawnmower onto its side,
empty the fuel tank completely with a petrol
pump. The lawnmower must not be tilted more
than 90 degrees. The simplest time to remove dirt
and grass is directly after mowing. Dried residual
grass and dirt could cause damage to the
mowing operation. Make sure the grass ejector
canal is free from residual pieces of grass and
remove these if necessary. Never clean the
mower with a direct jet of water or a high pressure
cleaner. The motor must stay dry. Aggressive
cleaning agents such as cold cleaning solvent or
petroleum ether must not be used.
7.2 Maintenance
7.2.1 Wheel axles and wheel hubs
These should be lightly greased once a season.
To do so, remove the wheel caps with a
screwdriver and slacken the fastening screws on
the wheels.
7.2.2 Blade
For safety reasons you should only ever have your
blade sharpened, balanced and mounted by a
service workshop. For optimum results it is
recommended that the blade should be
inspected once a year.
Changing the blade (Fig. 8)
Only ever use original spare parts when having
the blade replaced. The marking on the blade
must be matched with the number given in the
list of spare parts. Never have any other model of
blade fitted.
Damaged blades
Should the blade, in spite of all precautions,
come into contact with an obstruction, shut down
the engine immediately and pull the spark plug
boot. Tip the lawn mower onto its side and check
the blade for damage. Damaged or bent
blades must be replaced. Never attempt to
bend a bent blade back to straight again. Never
mow the lawn with a bent or heavily worn blade
as this will cause vibrations and can lead to further
damage to the lawn mower.
Important: There is a risk of injury if you work with a
damaged blade.
Resharpening the blade
The blades can be resharpened with a metal file.
In order to avoid imbalance, the blade should be
resharpened by a service workshop.
7.2.3 Care and adjustment of the cables
Oil the cables at regular intervals and check that
they move easily.
7.2.4 Repairs
After any repair or maintenance work, check that
all safety-related parts are in place and in proper
working order.
All parts which may cause injury must be kept
where they are inaccessible to children or others.
Important: In accordance with product liability
legislation we are not liable for any damages
caused by improper repairs or the use of spare
parts that are not original spare parts or parts
approved by us. In addition, we are also not liable
for any damages arising from improper repairs.
Such work should be performed by a customer
services workshop or authorized specialist. The
same applies to accessory parts.
7.2.5 Times of use
Please comply with statutory regulations, which
may vary from location to location.
7.3 Preparing the mower for
long-term storage
Caution: Do not empty the petrol tank in
enclosed areas, near fire or when smoking.
Petrol fumes can cause explosions and fire.
1. Empty the petrol tank with a petrol
suction pump.
2. Start the engine and let it run until any
remaining petrol has been used up.
3. Clean the cooling fins of the cylinder
and the housing.
