Store fuel in containers specifically designed for this
purpose.
Refuel outdoors only, before starting the engine and do
not smoke while refueling or handling fuel.
Never remove the cap of the fuel tank or add petrol while
the engine is running or when the engine is hot.
If petrol is spilled, do not attempt to start the engine but
move the machine away from the area of spillage and
avoid creating any source of ignition until petrol vapors
have dissipated.
Replace all fuel tanks and container caps securely.
Before tipping the lawn mower to maintain the blade or
drain oil, remove fuel from tank.

WARNING: Never fill fuel tank indoors, with
engine running or until the engine has been allowed to
cool for at least 15 minutes after running.

7-2 TO START ENGINE AND ENGAGE

BLADE

Release the brake control handle to stop the engine and
blade. (Fig. 8D)

Start the engine carefully according to

instructions and with feet well away from the blade.

Do not tilt the lawn mower when starting the
engine. Start the mower on a level surface, free of high
grass or obstacles.

14

Keep hands and feet away from the rotating
parts. Do not start the engine when standing in front of the
discharge opening.

7-3 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).

7-4 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.

7-5 CONNECTION FOR AUTO MOVE

For PLM4628N

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 fire hazard.

7-6 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
first 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
beneficial 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.

7-7 GRASS CATCHER

There is a window on the rear cover. You can see the
condition of grass catcher through the window. If the
catcher is full of grass; you will empty and clean the bag,
make sure it is clean and ensure its meshwork is
ventilated. (Fig. 10)

7-8 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).

7-9 HEIGHT ADJUSTMENT

INSTRUCTIONS

CAUTION: Do not at any time make any

adjustment to lawn mower without first stopping the
engine and disconnecting the spark plug wire.

CAUTION: Before changing mowing height, stop
mower and disconnect spark plug cable.

15

Your mower is equipped with a central height
adjustment lever offering 7 height positions.

1. Stop mower and disconnect spark plug cable before
changing mower cutting height.

2. The central height adjustment lever offers you 7
different height positions.

3. To change the height of cut, squeeze adjuster lever
toward the wheel, moving up or down to selected
height. (Fig. 11)

8. 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.

9. 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.

10. 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.

10-1 ENGINE AIR CLEANER

CAUTION: Do not allow dirt or dust to clog the air

filter 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.

To CLEAN AIR FILTER

1. Lift the tabs on top of the filter cover.

2. Remove the filter cover.

3. Wash filter element in soap water. DO NOT USE

GASOLINE!

4. Air dry filter element.

5. Place a few drops of SAE30 oil on the foam filter and
squeeze tightly to remove any excess oil.

6. Reinstall filter.

7. Close the filter cover.

NOTE: Replace filter if frayed, torn, damaged or
unable to be cleaned. (Fig. 12)

10-2 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 specified 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 resharpened by removing it and either grinding or
filing 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 crankshaft. Refer to Fig. 13. 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:

10-3 BLADE MOUNTING TORQUE

Center bolt 35 Nm - 45 Nm, 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 efficiently 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, you must use the original
type marked on the blade (Makita 263001451) (to order
the blade, please contact your local dealer or call our
company, see cover page).

10-4 ENGINE

Refer to the separate engine manual for 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.

16

Clean every few hours under extremely dusty conditions.
Poor engine performance and flooding 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 specifications.
Clean the engine regularly with a cloth or brush. Keep the
cooling system (blower housing area) clean to permit
proper air circulation which is essential to engine
performance and life. Be certain to remove all grass, dirt
and combustible debris from muffler area.

11. 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 fire, etc. Do not smoke!
Petrol fumes can cause explosion or fire.

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 fill 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
INSTRUCTIONS”.

3. Slightly grease the cutter to avoid corrosion.
