Basic Safety Instructions
These safety instructions apply universally to the use, care and
maintenance of the mower. They should always be observed and
are only generally listed here.
Prior to Start-up Please observe each time before starting up:
Read the operation manual (also for the engine) and keep in an
accessible place.
Check your mower for damages or leaks around the tank and
the engine.
Check the fuel and oil levels and add appropriate amounts and
grades as needed. Add fuel only in open spaces. Never smoke
while refuelling. Keep fuel and oil only in approved containers.
Ensure that filler caps for fuel and oil are tightly closed before
starting the engine.
Never exceed the MAX capacity for oil. Check the oil level
regularly. It should always be above MIN.
Change the oil after every 25 operating hours.
Do not refuel:
While the engine is running.
While the engine is warm.
Adjust the cutting height before starting the engine.
Check the following items before the first mowing:
The cutter is tightly fastened.
The handlebar and connections are tight.
The cables and controls are functioning properly.
GB

Icons
During Start-up Always wear appropriate shoes/boots with sufficient tread. The
cutting tool runs at a high speed and can throw foreign objects such
as stones or branches out from the mower. Protect yourself with
appropriate work attire.
Always begin mowing on an open surface, not in high grass. Start
the engine only when the mower is securely stationary and the blade
can rotate freely.
Do NOT start:
In enclosed areas, because a running engine produces carbon
monoxide, a poisonous, odourless, colourless gas.
If you are not standing behind the grip handle facing the direction
of travel.
If the starter coil is not in the cable holder hanging on the grip
handle.
If the mower is not stationary.
If there is discernible damage to the mower or safety equipment
is defective.
If persons or animals are in the hazard area (approx. a 5-metre
radius).

If fuel was spilled next to or on the mower during fuelling;
thoroughly clean up the spill prior to starting to avoid possible
ignition.
If brightness/daylight is insufficient to allow safe working
conditions.
Please observe all community ordinances regarding permissible
operating times for private use.
Further operating times apply to commercial use.
Operation Never modify the engine’s factory settings. The RPM is preset by the
manufacturer and may not be altered.
Prior to mowing, clear the area to be mowed of any stones, wood,
glass, wire and other foreign objects that could harm you or the
cutting tool.
Operation is permitted only if the grip handle is locked tightly in
position. This is the only way you can safely move the mower and
remain a safe distance from the rotating blade.
Always mow across inclined surfaces, as this is much safer. Inclined
surfaces such as hillsides at greater than 20° grade should not be
mowed. Mowing over loose surfaces or paths increased the risk of
impact from stones. Always turn off the engine when travelling
across such surfaces. Restart the engine only after reaching the
work area.
The exhaust pipe presents a burning hazard. T
emperatures can reach
up to 80°C. Keep fuel, oil, grass, leaves and other flammable or easily
ignitable materials a safe distance from the exhaust pipe and engine.

7Operation Manual HM / PM - 01/08

Description
Adding Oil ATTENTION!
Checking the oil level accurately is possible only
when the mower is parked on as level a surface as
possible. Deviations up to 3% incline are within an
acceptable range. Change the oil after very 25
hours of operation in order to avoid engine
damage.
Use only oil recommended by the engine
manufacturer.
Environmental Protection
Be careful when handling fuel and oil to make sure
nothing ends up in the environment.
Recycle residual fuel and used oil responsibly.
Proceed as follows to add oil:
1. Pour 500 ml (for HM models) or 600 ml (for PM
models) of oil into the infill spout using a funnel.
2. Replace the oil fill cap on the infill spout.
3. Remove the oil fill cap from the infill spout (6) again
and check the level on the dipstick (6). The oil level
should be close to MAX (7). A correct oil level
should always fall between MAX (7) and MIN (8).
4. Replace the infill spout cap (6) and hand-tighten it.
Note the notches in the infill spout.
Adding Fuel WARNING!
Danger of explosion! Petrol is highly flammable and
petrol vapours can easily explode! Turn off the
engine. Refuel only in open spaces. Keep a 5-metre
radius from fire or open flame. No smoking. Never
refuel when the engine is warm.
1. Park the mower on a somewhat level surface. Let
the engine cool before refuelling.
2. Remove heavy soil around the filler cap (9) before
opening. Open the filler cap (9).
3. Add unleaded regular fuel (91 octane) using a
safety spout or a funnel. Maintain the maximum
fuel capacity recommended by the engine
manufacturer.
4. Make sure that there is sufficient air to allow
dissipation of fuel fumes.
Always keep away from shaken/foaming fuel. Do not
mix oil with fuel. Close the filler cap by hand-tightening
it.

mower.
Preparing for
Starting Engine
WARNING!
Injury hazard! Start the mower only when you are
standing behind the grip handle.
The starter coil handle (14) is easily reachable from this
position. If the starter coil handle is still coiled in the
engine, requiring you to stand beside the mower to start
it, your feet are in danger of injury because they are in
the cutting rotation zone. Starting the engine only while
standing behind the grip handle protects you from foot
injury from a running engine.
Park the mower on a level surface.
Avoid areas:
With high grass (hindering blade rotation).
With gravel, dust, and broken surfaces.
The cutting tool produces strong air movement.
Starting Engine
Easy-Start Engine 0050(see p. II) (for Type PM53A)
For a cold start, depress the rubber fuel injection primer
(12) once. After about 2 seconds, depress the primer
once more. The primer should be depressed only 2 or 3
times for a cold start. If the engine is warm, starting is
usually possible without depressing the primer. Do not
depress the primer (12) unnecessarily; each depression
injects fuel into the carburettor intake. Flooding the
engine may prevent ignition. In temperatures below
10°C, however, it may be necessary to pump the primer
up to 5 times.
Ready-Start Engines (for Types HM46 and HM46A)
No additional preparations are necessary.
Stand behind the mower and pull the engine brake bar
(13) to the handle bar (1) with one hand; with the other
hand grasp the starter coil handle (14) hanging in the
cable holder (11).
GB
9Operation Manual HM / PM - 01/08

Description
Starting Engine
0060(see p. II)
NOTE:
Starting with the starter coil is possible only when
the engine brake bar is retracted; otherwise the
engine brake prevents ignition.
With the engine brake bar (13), pull the starter coil
handle (14) swiftly with equally strong arm movements,
and hold onto it even after the engine has started.
Once the engine starts, slowly return the starter coil
handle (14) to the cable holder (11). If the engine does
not immediately start, repeat the attempt.
Do not begin mowing immediately after starting the
engine; rather, allow it to warm up for about 2 minutes.
ATTENTION!
Too many attempts to start the engine will flood it.
This allows too much fuel into the cylinder
chamber, and the spark plug will not ignite
anymore. If you are unable to start the engine after
multiple attempts, the cause should be determined.
Please also check your engine documentation.
NOTE:
If the engine becomes flooded after multiple
attempts to start it, proceed as follows:
1. Remove the spark plug cap.
2. Unscrew the spark plug.
3. Pull the starter coil several times to dry out the
cylinder chamber.
4. Dry off the spark plug and screw it back in
tightly.
5. Replace the spark plug cap.
6. Start the engine.
Model HM46A/PM53A (with wheel drive) 0060
If you would like to use the mower’s self-propelled
feature, pull the clutch lever for the wheel drive (21)
toward the handle bar; otherwise, you can push the
mower by hand without engaging the clutch.
Model PM53A 0080(see p. II)
To select the drive speed, move the speed lever (5) to
the desired position (slow/1st gear: I; fast/2nd gear: II).
Move the speed lever only when the wheel drive is
disengaged (clutch lever (21) is not pulled). Otherwise,
operate as described for Model HM46A.

Description
Cutting Method
The grass is chopped into very fine pieces by a special
blade, breaking up its structure.
These clippings are then pressed back down into the
surface through the topsoil.
The clippings decay in a very short time and thereby
supply the ground with nutrients.
This allows mowing grass regardless of the weather
without impairing the results.
Benefits:
No clipping removal.
No composting.
At least 50% time savings.
At least 50% savings in watering.
Outstanding cut with no remaining missed areas on
the topsoil.
Optimising Mowing You will get the smoothest results
if you observe the following:
Set the cutting height according to the indicator on
the mower or as instructed in this operation manual.
Mow at maximum grass height of 120 mm.
Grass standing higher than 120 mm may leave uncut or
uneven areas and may also clog the mower and stop
the engine.
Mowing wet grass inevitably results in piles of clippings
left on the lawn after shutting off the mower, regardless
of the height of the mown area. These should be
removed after mowing.
Stopping Operation
0070(see p. II)
WARNING!
Injury hazard from continuing blade rotation!
The blade continues to rotate after the engine has
been shut off (for about 2 seconds). Do not place
your hands under the blade guard immediately after
shutting off the engine.
Release the engine brake bar (13) to stop the engine.
Wait for the blade to stop turning.
Conduct the following maintenance and care measures
before parking/storing the mower.
Parking Short-term storage of mower (up to 4 weeks) is
considered "parking".
Storing "Storing" is considered long-term non-use of the mower
for more than 4 weeks, e.g. over the winter.
GB
11 Operation Manual HM / PM - 01/08

Maintenance and Care
6Maintenance and
Care
ATTENTION!
Perform all maintenance and care procedures only
when the engine is shut off and the cutting tool is
stationary. Be sure also to heed the instructions
from the engine manufacturer when performing
maintenance and care procedures. Do not spray the
engine down. Pull the spark plug cap.
Tip the mower only after the cutting tool has come
to a stop.
Check the fuel tank level. The fuel tank must not be
filled to capacity, otherwise fuel will run out.
ATTENTION! The engine is warm after use. Touch
only the fuel tank cap when checking the level.
Always tip the mower toward the back 0040.
Check the fuel tank level in advance. The fuel tank must
not be filled to capacity, otherwise fuel will run out.
Park the mower securely on an even surface. Place the
height adjustment lever in the transport position; then
release the eccentric lever on the handle bar and fold
the handle bar forward completely. Grasp the handle
on the carrier and pull the mower upright.
After Mowing/Before
Parking and/or Storing
Wear gloves to protect your hands when working
around the blade.
Thoroughly clean the mower after use. Do not use a
pressure washer for cleaning. Remove clipping residue
by hand using only a brush or scraper.
Park the mower under a covered area. Petrol can
remain in the fuel tank.
The mower should not be parked in the sun and not
inside a residence, because of the emission of petrol
fumes.
Let the engine cool outdoors before parking.
For safety reasons, worn-out or damaged mower parts
must be replaced before further use.
If you sense vibrations during engine operation, consult
your dealer. Do not attempt to eliminate the vibrations
yourself.
Keep the locking torque at 20 Nm for mounting the
cutting tool. The use of torque wrench is mandatory.

Every 25 hours of operation
Before parking/storing
The maintenance/care intervals should be shortened if the mower is frequently
operated in extreme temperatures or in dusty environments.
Draining/Changing
oil
Changing the oil should ideally take place while the
engine is warm, because the used oil and all residue
more easily drains from the engine. Oil should be
changed only through the infill spout (6).
Watch out for the cutting tool!
The exhaust pipe may remain very how after
stopping the engine. Injury hazard!
Draining Oil with Hand
Pump
The oil can be pumped out using a standard hand
pump. If necessary, go to your nearest service station
or your dealer (see engine service list). Please heed
your engine manufacturer’s operation manual.
Draining Oil without
Hand Pump
Pull the spark plug cap off the spark plug.
Raise the mower off the ground. Place next to the
mower an appropriate container the height of the infill
spout for catching the used oil.
Open the oil infill spout and tip the mower to the side
until all the oil has run out of the engine.
Protect the environment.
Recycle used oil responsibly by delivering it to a
service station, who will accept it at no charge. Oil
that ends up in the environment causes damage to
the water table.
GB
13 Operation Manual HM / PM - 01/08

Maintenance and Care / Resuming Operation
Sharpening Blade WARNING!
Acutting tool (blade) that produces vibrations
must be replaced without fail. Do not attempt to
true the blade yourself, as you may get it out of
balance. This can cause an accident and create the
hazard of further damage to the mower.
Blade grinding is rarely necessary, since the blade is
manufactured from a specially hardened steel.
If it becomes necessary to resharpen your blade,
please bring it to us or to a dealer in your area.
Obtaining Replacement
Parts
ATTENTION!
Accident hazard from using damaged parts!
For safety reasons, worn or damaged parts must
be replaced. Only original replacement parts may

Warranty Terms
10 Warranty Terms
MWS Cutting Tools Ltd. & Co, located at Asbacher Str. 5, 98574 Schmalkalden, Germany (hereafter "MWS") hereby guarantees the end-
user that its walking mower is manufactured according to the latest engineering standards and is free of defects and
workmanship for its intended use. In accordance with this guarantee MWS will relieve the end-user of any costs related to the elimination of
defects in materials and workmanship through an MWS-contracted dealer or MWS itself (claim) under the following conditions:
1
The warranty period begins on the date of purchase - a completed warranty card, dealer stamp and dealer invoice.
2
The warranty period ends after 24 months from the date of delivery to the end-user (purchase) has passed. Exceptions to the are MWS
power equipment that is used for public or commercial purposes, even if only temporarily. In such cases the warranty expires after 12
months. Engines installed on the equipment are excluded from this warranty. For these, the manufacturer's conditions apply as shown
below.
Engine Warranty Periods (according to information supplied by each manufacturer)
Problems that MWS itself or its contract dealers are notified of after expiration of the warranty period have no basis for a warranty claim.
Each warranty claim is subject to a limitation of 6 months after discovery of the problem.
3
The manufacturer is not responsible for damages to the equipment or subsequent damages to persons or property that arise due to
inappropriate use; no warranty claims can be validated. Deficiencies and subsequent repairs are handled by our customer service
department. Further claims beyond the warranty are excluded. There is no guarantee of replacement.
4
The following are excluded from the warranty:
Maintenance and cleaning labour.
Installation of non-OEM parts.
User-serviced repairs and self-performed modifications.
Alterations in construction.
Normal wear and tear, as well as wear due to inappropriate use (overuse) such as filters, spark plugs, wheels, friction surfaces,
blades and turbodiscs, cutter housings, bent support frames, welded and attached parts broken off due to improper operation and
transport and other consumable parts, as well as accessories not belonging to the model.
Paint damage from use.
5
The service provider is responsible for any damage caused in transport, i.e. the carrier or shipper, not the manufacturer.
6
MWS reserves the right to repair defective parts or replace them. Replaced parts become the property of MWS without compensation. The
MWS contract dealer used to eliminate the problem does not have the authority to make binding declarations in the name of MWS.
7
MWS reserve the right to refuse fulfilment of warranty claims if and insofar as:
a) the MWS contract dealer engaged by the end-user for eliminating the problem has not correctly filed a completed warranty work order
b) Improper handling not in keeping with the operation manual, particularly overuse of the purchased item by the end-user, has led to the
occurrence of damage to the item due to defects in materials and workmanship
c) The end-user has not observed important instructions in the operation manual, particularly safety instructions
d) The purchased item has been in some way overhauled, modified, or outfitted with parts or accessories that do not belong to the
equipment expressed approved or recommended by MWS, or parts other than original replacement parts have been used in maintenance
or repair of the purchased item.
8
In addition to claims arising from this warranty, the end-user has other legal guarantees and rights arising from the sales contract with the
dealer that are not limited by this warranty.
