7.2 Assembly
Your lawnmower will be ready for use in only a few
steps.
Securing the handle:
• Open locking screws (8)
• Pivot the upper handle into the required position
– if required, release locking screws (8) a little.
• Turn the open locking screw far enough
inwards to ensure that both handle parts sit
closely together when the locking levers are
closed. If required, either tighten or relax the
locking screws by one full turn.
Tip: Lock the locking screw levers upwards to
ensure that, whilst mowing, the screws do not
catch on shrubs.
Secure the Bowden and other cables in the cable
guides.
Folding the handle again for transport or storage:
When folding the handle, open both locking
screws upwards and tilt the upper handle forward.
Note: On lawnmowers with self-drive, push the
control bar (2) against the handle, before folding
the handle over, to prevent damaging the spark
plug

Caution! Assure that Bowden cables are not
caught up anywhere and that they have not
become damaged during transport!
ENGLISH 10
The mower is equipped with a continuously
adjustable cutting height of approx. 30 - 75 mm
(approx. 1 - 3 inches). The height adjustment for all
wheels is accomplished by the central adjustment
(position 11). Turning to the right reduces the
cutting height, and turning to the left increases the
height. The height can be read from the markings.
Attention: The cutting height is to be set so that
the blade does not touch the ground when the
ground is not level. Only mow with the lowest
cutting adjustment when lawns are flat.
Starting / Stopping the engine
8. Starting / Stopping the engine
During start up with self-propelled drive roller
mower, the drive has to be disengaged.
When starting the mower, position yourself on the
side or behind the mower. The safety distance
which is given by the handle is always to be
adhered to.
Caution! The cutter operates as soon as the
engine starts! Never reach with your hands under
the deck and never slide a foot under the deck!
8.1 Starting

temperature (Ready-Start®). These models
require no manual adjustment for a cold start.
Starting:
Attention: To release the engine brake when
starting the engine, the brake bar (1), needs to be
pushed towards the handle.
If the brake bar (1) is not pushed to the handle
during start, the electrical ignition is shorted and
the engine brake is activated. In this situation, the
engine cannot be started with manual start up and
electric start.
Model 546, 546R, 546HR:
Pull out starter rope until resistance is felt - then
pull rapidly and with force.
Electrical Starter (546RS):
Put the ignition key in the ignition (4) on the throttle
lever and turn 1/4 clock-wise.
ENGLISH 11
Mowing hints
9. Mowing hints
When mowing, please observe the safety
recommendations which are part of this owners
manual!
Important Note: The time and duration
when lawn mowers can be operated may be
subject to local ordinances. These ordinances
usually vary from location to location.
Noise is damaging. During extended
mowing, we recommend wearing protective head
gear to avoid possible hearing loss.
Before mowing, search the lawn and carefully
remove any debris (stones, shards, metal objects,
twigs, etc.). Leaves, cuttings, etc. do not need to
be removed prior to mowing, but can be picked up
with the grass catcher.
Note: If, on account of the growth pattern, the full
engine power is not required, you can select the
Eco position (“Öko”) between max. and min. on
the throttle control (Fig. 5) to protect the
environment.
9.1 Mowing with Grass catching device
Short and dry grass can be easily blown in the
grass catching device (6). This is made possible
by blower-supported grass ejection (turbo effect).
Fig. 6
The shorter the cuttings, the better the grass
catcher handles them;
- excessively long or wet grass could possibly
clog-up the catcher or slow down the pick-up.
In case of long grass, therefore, first cut with a
higher setting in one direction (with generous
overlap) and then across the first pattern with a
lower or the standard cutting height (Fig. 6).
ENGLISH 12
Grass height, density and grass dampness
determine cutting results. Grass that is dry and not
too long assures best cutting results. Wet grass
may be cut and collected; however, the cutting
results and the collection outcome are affected. A
sharp blade is essential for best cutting results. A
dull blade (grass stems become ragged during
cutting and the lawn turns yellow) has to be
resharpened (see chapter „Blade“).
9.2 Lawn Care
If possible, mow only when the lawn is dry and
when the ground is dry. The lawn mower‘s wheels
press into the wet ground and leave compression
marks.
A lawn looks better and appears more uniform if
cut often. Frequent cutting allows the lawn to
become healthy since the growth goes into the
stem.
Short cuttings up to 1 cm (approx. 1/2 inch) may be
left on the ground, longer cuttings need to be
collected with the grass catching device. At Spring
time, the first mowing should take place approx. 2
to 3 weeks before the grass grows at its usual
level. In order to achieve early greening of the
lawn, cut only approx. 1.5 cm (3/4 inch) of the
grass. Check lawn for foreign objects (rocks, glass,
metal pieces etc.) prior to mowing lawn. The grass
catching device can be used for any additional
clean-up (leaves etc.).
Newly seeded or thin lawns must not be cut too
short (leave 3 - 4 cm) (1 - 1 1/2 inches). Let the
grass remain at that length for 4 to 5 weeks, so that
the lawn increases in width and density.
Attention: SOLO Lawn mowers with rear eject are
especially suited for the collection of leaves.
However, this use is only permitted on lawns
where all foreign objects, such as stones,
shards, metal objects, twigs, etc. have first
been carefully removed. Leaf collection on solid
ground (for example, roads or walk-ways) is
prohibited due to inherent safety risks.
For leaf collection, the cutting height is to be set to
the middle or to the highest setting.
Maintenance and Care
10. Maintenance and Care
For your own safety, remove the spark
plug cap from the spark plug prior to any
maintenance work or cleaning (12).
Any maintenance and care that go
beyond the described explanations need
to be left to an authorized Service Center.
10.2 Wheel axles and wheel hubs
Fig. 8
10.1 Cleaning the Mower
After each use, the mower needs to be thoroughly
cleaned. Special attention needs to be given to the
lower side, the blade and the cutting area circle.
Tip: To enable the lawnmower to be maintained
and cleaned with an empty fuel tank, fill only
enough fuel for the mowing job in hand. That way,
the tank can be quickly emptied after mowing has
been completed.
Fig. 7
Wheel axles and wheel hubs are to be lubricated
occasionally (at least once a year). Remove wheel
cap, release screw and remove wheel. During
disassembly observe the sequence for the
reassembly of the parts. We recommend SOLO
bearing grease,
part no. 00 83 175.
Maintenance of the rear wheel-self-propelled drive
roller:
Fig. 9
After releasing locking screws (8), the mower can
be raised onto its rear wheels and be supported on
the lower handle. First pull the spark plug cap. The
fuel tank should be empty, if possible, to prevent
fuel spilling from the fuel tank cap. Catch any fuel
running out of the carburettor with a suitable rag.
Dirt and grass debris is removed easily
immediately after mowing. Imbedded grass debris
and dirt on the mower deck‘s lower section
interrupt the grass collection and affect cutting
results. Imbedded dirt on the blade and on the
blower wheel lead to imbalance and consequently
to vibration. Check also for cleanliness of the duct.
The ejection air duct can be cleaned with a small
stick or with a screw driver.
Do not spray the mower with a hose or high
pressure cleaning hose. The engine has to
remain dry. The outer deck parts can simply be
kept clean by wiping the unit off with a rag. Strong
cleaning agents of any kind are not to be used.
• After removing wheel caps and loosening
fastening screws, remove drive wheels.
• Remove grass debris and dirt from all drive
wheel areas.
Attention: Do not remove neutral gear pinions
from the gear shaft; however, check if they turn
slightly counter-clockwise to the drive direction.
• Lightly lubricate the two pinions (free wheel and
plastic pinion) with water-repellent grease which
is compatible with plastic, e.g. SOLO bearing
lubricant, part no. 00 83 175.
• Fill the space inside the drive wheel between
both taper bearings with the same or a
compatible grease.
• Also lubricate the wheel axles with grease.
• When refitting the drive wheel, ensure that both
pinions engage with each other; slightly turn the
wheel on its axle, if required.
ENGLISH 13
Maintenance and Care
10.3 Height adjustment
10.5 Oil level check
Before storing your lawnmower out of season
clean and lubricate the wheel adjuster spindle with
grease (this procedure is necessary at least
annually).
For this, set the wheel adjuster to its highest
position (max)
- clean and lubricate the exposed part of the
spindle with grease
- then set the wheel adjuster to its lowest position
(min)
- clean and lubricate the remaining spindle with
grease. For this, we recommend SOLO bearing
grease, part no. 00 83 175.
Attention: The engine oil affects the lawn mower‘s
efficiency and life span. Never operate the engine
without oil or with little oil. Major engine damage
can occur. The optimum viscosity depends on
where the lawn mower is used (air temperature
and altitude) and can be found in the engine
owners manual.
Checking Oil level:
10.4 Drive belt
Tensioning the drive belt
Fig. 10
Observe the notes and instructions in the typespeci.c engine operating instructions.
Fig. 11
• Place lawn mower
horizontally with all
wheels on the ground.
• Turn oil tank cap
counter-clock-wise
(14), and remove. Wipe
off dipstick.
• Place dipstick back into
filler pipe.
Remove the lid from the battery/gearbox chamber
(15) after releasing both screws. Undo the fixing
screw (C) of the tensioning lever. Tension the
drive belt by moving the tensioning lever (in the
direction of the arrow).
Note: Check the belt tension every 20 hours or at
least once per mowing season.
The belt is correctly tensioned of the centre can be
deflected by approx. its own thickness.
Changing the drive belt
• Position the lawn mower on its handle and
discharge deflector (Fig. 7). First pull the spark
plug cap and ensure that the fuel tank is empty.
• First remove the blade and impeller, then the
old drive belt.
• Position the new drive belt from below onto belt
pulley A and insert to the rear into the mower
chassis.
• Reposition the mower on its wheels.
• Position the drive belt onto pulley B on the
gearbox side.
• Tighten V-belt as described above.
• Screw on cap tightly.
• Assemble blower wheel and blade. Observe
sequence of assembly parts and observe the
blade‘s torque. (Fig. 12).
ENGLISH 14
• Remove dipstick, hold horizontally and read oil
level. Oil level has to be between the
"MAXIMUM" and "MINIMUM" markings.
Changing Oil (Briggs&Stratton 4-cycle engine)
The engine oil may be drained via the oil drain
screw or the oil filler opening. Blade and blower
wheel need to be removed to reach the oil drain
screw (illustration 11). Observe especially the
service instructions in the separate engine owners
manual.
For the oil change with the HONDA OHC
Engine, the used oil is removed by suction
wich should only be done by a specialist
workshop.
When draining via oil filler opening (14): Tilt the
warm mower (with fuel tank empty and closed oil
filler ) slowly over the side of the filler opening.
Remove oil filler cap and catch old oil in a
container. Wait several minutes until oil is drained.
Dispose off the old oil in accordance with local
ordinances.
After changing oil, always wash hands with a
scouring agent, soap and water.
Attention: Never simply throw away used engine
oil and gear lubricant (environmental protection).
Collect used oil in authorized containers and
submit to the proper recycling facility.
Gearbox (546R / 546HR / 546RS)
The gear is equipped with a special permanent oil
and operates completely maintenance-free.
Technical faults that cannot be resolved by
adjusting the Bowden throttle cable are only to be
corrected by an authorized Service Center.
Maintenance and Care
10.6 Mowing Blade
Special tools, such as a torque wrench for
example, are required to mount the blade to
the mower. For safety reasons we recommend
that the mowing blade is sharpened, balanced and
re-fitted by an authorized specialist workshop only.
The following notes are therefore only intended for
specialist repair shops.
To obtain best mowing results we recommend to
have the blade sharpened / balanced or at least
once every year.
Replacement of Blade
Proper gloves are to be worn when
replacing the blade. The spark plug
cap has to be removed prior to any
work.
Damaged Blade
The engine needs to be shut off and the spark plug
cap has to be removed if the blade has come in
contact with a foreign object or other obstacle.
After the blade stops, tilt the mower and check the
blade for damage. Deformed or bent blades are not
to be re-aligned.
Damaged parts are to be replaced immediately. If
the mower has been driven over a notable
obstacle, the mower needs to be checked by an
authorized Service Center. Prior to use make
certain that blade and blade fastening parts are not
damaged. If necessary, parts need to be checked
or replaced. Never operate mower with an
unbalanced blade - this would cause vibration and
additional damage.
Sharpening of Blade
Fig. 13
Fig. 12
Attention: The blade may be sharpened with a
metal file; however, we recommend that
resharpening/sanding is done by an authorized
Service Center who will pay attention that the same
amount is sanded off on each side to avoid any
imbalance.
The cutting edge of the blade is only be resanded
up to the imprinted markings.
10.7 Air filter Maintenance
When replacing any blade parts only SOLO spare
parts are to be used. The identification No. on the
blade has to agree with the Order No. for the
replacement. Never install a different type of
blade!
Use the holding pin as a blocking device for the
blade. The blade fastening screw has a regular
right-handed thread. To remove the screw we
recommend using a socket wrench 21 mm (spark
plug wrench) or hex. wrench 8 mm, 5/16“. At reassembly of the overload clutch be sure and
observe the sequence in which these parts where
previously assembled. The blade screw is to be
tightened with the specified torque of 45Nm
(4,5mkp).
Attention: Dirty air filters reduce the engine‘s
efficiency, the carburetor does not receive
sufficient air flow. Routine inspection, especially in
dusty conditions, is essential.
Attention: Never clean air filter parts with gasoline
or flammable solvents. Danger of fire or explosion!
Observe all instructions in the respective engine
owners manual.
