10.3 OPERATION PROCEDURES
During operation, tightly hold the brake handle with both
hands.
NOTE:
• During operation, when the brake handle is released,
the engine will stop and thus stopping the lawn mower
from operating.
WARNING:
• In order to avoid any unintentional start-ups of the lawn
mower, it comes equipped with an engine brake 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.
NOTE:
• Engine brake (brake handle): 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. 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 kinking
in any way).
10.4 TO STOP ENGINE
CAUTION:
• The blade continues to rotate for a few seconds after
the engine is shut off.
1. Release the brake control handle to stop the engine
and blade.
2. Disconnect and ground the spark plug wire as
instructed in the separate engine manual to prevent
accidental starting while equipment is unattended.
10.5 CONNECTION FOR AUTO MOVE
For PM-4820 S
Grip the self-drive control handle, the lawn mower will
move forward automatically with about 3.6 km/h (Fig. 9),
release the self-drive handle, the lawn mower will stop
move.
CAUTION:
• Your mower is designed to cut normal residential grass
of a height no more than 250 mm.
Do not attempt to mow through unusually tall dry or wet
grass (e.g., pasture) or piles of dry leaves. Debris may
build up on the mower deck or contact the engine exhaust
presenting a potential re hazard.
10.6 FOR THE BEST RESULTS WHEN
MOWING
Clear lawn of debris. Be sure that the lawn is clear of
stones, sticks, wire or other foreign objects which could
be accidentally thrown out by the mower in any direction
and cause serious personal injury to the operator and
others as well as damage to property and surrounding
objects. Do not cut wet grass. For effective mowing
do not cut wet grass because it tends to stick to the
underside of the deck preventing proper mowing of the
grass clippings. Cut no more than 1/3 the length of the
grass. The recommended cut for mowing is 1/3 the length
of the grass. Ground speed will need to be adjusted so
the clippings can be dispersed evenly into the lawn.
For especially heavy cutting in thick grass it may be
necessary to use one of the slowest speeds in order to
get a clean well mowed cut. When mowing long grass
you may have to cut the lawn in two passes, lowering the
blade another 1/3 of the length for the second cut and
perhaps cutting in a different pattern than was used the
rst time. Overlapping the cut a little on each pass will
also help to clean up any stray clippings left on the lawn.
The mower should always be operated at full throttle
to get the best cut and allow it to do the most effective
job of mowing. Clean underside of deck. Be certain to
clean the underside of the cutting deck after each use
to avoid a build-up of grass, which would prevent proper
mulching. Mowing leaves. The mowing of leaves can also
be benecial to your lawn. When mowing leaves make
sure they are dry and are not laying too thick on the lawn.
Do not wait for all the leaves to be off the trees before
you mow.
WARNING:
• If you strike a foreign object, stop the engine. Remove
wire from spark plug, thoroughly inspect the mower for
any damage and repair the damage before restarting
and operating the mower. Extensive vibration of the
mower during operation is an indication of damage.
The unit should be promptly inspected and repaired.

14
10.7 DECK
The underside of the mower deck should be cleaned after
each use to prevent a buildup of grass clippings, leaves,
dirt or other matter. If this debris is allowed to accumulate,
it will invite rust and corrosion, and may prevent proper
mulching. The deck may be cleaned by tilting the mower
and scraping clean with a suitable tool (make certain the
spark plug wire is disconnected).
11. MAINTENANCE INSTRUCTIONS
SPARK PLUG
Use only original replacement spark plug. For best
results, replace the spark plug every 100 hours of use.
BRAKE PADS
Check and/or replace the engine brake pads in service
agent regularly, only original parts can be used as
replacement.
12. LUBRICATION INSTRUCTIONS
CAUTION:
• DISCONNECT SPARK PLUG BEFORE SERVICING.
1. WHEELS – Lubricate the ball bearings in each wheel
at least once a season with a light oil.
2. ENGINE – Follow engine manual for lubrication
instructions.
3. BLADE CONTROL – Lubricate the pivot points on the
blade control handle and the brake cable at least once
a season with light oil. The blade control must operate
freely in both directions.
13. CLEANING
CAUTION:
• Do not hose engine. Water can damage engine or
contaminate the fuel system.
1. Wipe deck with dry cloth.
2. Hose under deck by tilting the mower so that the spark
plug is up.
13.1 ENGINE AIR CLEANER
CAUTION:
• Do not allow dirt or dust to clog the air lter foam
element. The engine air cleaner element must be
serviced (cleaned) after 25 hours normal mowing. The
foam element must be serviced regularly if the mower
is used in dry dusty conditions. (Refer to ENGINE
OWNER’S MANUAL.)
To CLEAN AIR FILTER
1. Lift the tabs (19) on top of the lter cover. (Fig. 10)
2. Remove cover.
3. Wash lter element in soap water. DO NOT USE
GASOLINE!
4. Air dry lter element.
5. Place a few drops of SAE30 oil on the foam lter and
squeeze tightly to remove any excess oil.
6. Reinstall lter.
7. Close the lter cover.
NOTE:
• Replace lter if frayed, torn, damaged or unable to be
cleaned.
13.2 CUTTING BLADE
CAUTION:
• Be sure to disconnect and ground the spark plug
wire before working on the cutting blade to prevent
accidental engine starting. Protect hands by using
heavy gloves or a rag to grasp the cutting blades.
Tip mower as specied in separate engine manual.
Remove the hex bolt and washer which hold the blade
and blade adapter to the engine crankshaft. Remove
the blade and adapter from the crankshaft.
WARNING:
• Periodically inspect the blade adapter for cracks,
especially if you strike a foreign object. Replace when
necessary.
For best results your blade should be sharp. The blade
may be retargeted by removing it and either grinding or
ling the cutting edge keeping as close to the original
bevel as possible. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. Improper blade balance will
result in excessive vibration causing eventual damage to
the engine and mower. Be sure to carefully balance blade
after sharpening. The blade can be tested for balance by
balancing it on a round shaft screwdriver. Remove metal
from the heavy side until it balances evenly.
Before reassembling the blade and the blade adapter
to the unit, lubricate the engine crankshaft and the inner
surface of the blade adapter with light oil. Install the blade
adapter on the engine crankshaft. Refer to Fig. 11. Place
the blade with the part number facing away from the
adapter. Align the washer over the blade and insert the
hex bolt. Tighten the hex bolt to the torque listed below:
13.3 BLADE MOUNTING TORQUE
Center Bolt 40 N•m – 50 N•m, to insure safe operation of
your unit. ALL nuts and bolts must be checked periodically
for correct tightness.
After prolonged use, especially in sandy soil conditions,
the blade will become worn and lose some of the original
shape. Cutting efciently will be reduced and the blade
should be replaced. Replace with an approved factory
replacement blade only. Possible damage resulting from
blade unbalance condition is not the responsibility of the
manufacturer.
When you change the blade, Must use the original type
marked on the blade (DOLMAR 263003054) (for order the
blade, pls. contact your local dealer or call our company).
WARNING:
• Do not touch rotating blade.

15
13.4 ENGINE

maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
Service air cleaner as per separate engine manual under
normal conditions.
Clean every few hours under extremely dusty conditions.
Poor engine performance and ooding usually indicates
that the air cleaner should be serviced.
To service the air cleaner, refer to the separate engine
manual packed with your unit.
The spark plug should be cleaned and the gap reset once
a season. Spark plug replacement is recommended at
the start of each mowing season; check engine manual
for correct plug type and gap specications.

14. STORAGE INSTRUCTIONS
(OFF SEASON)
The following steps should be taken to prepare lawn
mower for storage.
1. Empty the tank after the last mowing of the season.
a) Empty the petrol tank with a suction pump.
CAUTION:
• Do not drain the petrol in closed rooms, in close
proximity of open re, etc. Do not smoke! Petrol fumes
can cause explosion or re.
b) Start the engine and let it run until it has used up all
remaining petrol and stalls.
c) Remove the spark plug. Use an oilcan to ll approx.
20 ml oil into the combustion chamber. Operate the
starter to evenly distribute the oil in the combustion
chamber. Replace the spark plug.
2. Clean and grease the lawn mower carefully as
described above under “Lubrication”.
3. Slightly grease the cutter to avoid corrosion.
4. Store the lawn mower in a dry, clean and frost-
protected place, out of reach of unauthorized persons.
CAUTION:
• The engine must have completely cooled down before
storing the lawn mower.
