Makita Lawn Mower PTM0900 PTM0901 PTM0903 Instructions Manual

							6.4.4 Replacing a fuse
The machine is fitted with fuses (1) with
different capacities and functions. Specifi-
cally:
– 10 A fuse = protects the main and
power circuits of the electronic circuit
board. When it blows, the machine
stops and the dashboard light switches
off.
– 25 A fuse = protects the battery charger
circuit. When it blows, the battery grad-
ually runs out and the machine will have
problems starting.
The fuse capacity is indicated on the fuse.
A blown fuse must
always be replaced by one of the same
type and ampere rating, and never with
one of another rating.
If problems persist, contact Your Dealer.

6.5.2 Dismantling, replacing and remounting the blades
Always wear work
gloves when handling the blades.
Damaged or bent
blades must always be replaced;
never try to repair them! ALWAYS USE
ORIGINAL BLADES BEARING THE
SYMBOL   ! Make sure the blades
are correctly balanced. The blades are
different and rotate in different direc-
tions, so make sure you put them
back in the right place by referring to
the code stamped on the outside of
each blade. 
1. Dismantling
1a= screw with right thread (loosen anti-
clockwise)
1b= screw with left thread (tighten clock-
wise)
2. Original spare parts
Only the following pairs of blades can be
used on this machine:
2b 82004345/1 82004344/1 2a
2b 82004354/0 82004353/0 2a
3. Remounting
Check that the concave part of the cushion
disc (3) presses against the blade.
Remount the shaft hubs (4), making sure
that the keys (5) are securely lodged in
place.
4. Tightening the screws
1a= screw with right thread (tighten clock-
wise)
1b= screw with left thread (tighten anti-
clockwise)
Tighten with a torque wrenchcalibrated
to 40-45 Nm.

1.When the key isturned to “RUN”, theindicator light or thecontrol panel remainswitched off
2.With the key on«START» the lightflashes and thestarter motor doesnot run
3.With the key isturned to “START”the light or the con-trol panel come on,but the starter motoris not activated
4.With the key on«START»,  the startermotor runs but theengine does not start
5.Starting is difficultor the engine runserratically
6.Poor engine per-formance during cut-ting
The safety device of the electronic cir-cuit board has cut in due to:
– badly connected battery  – battery terminals crossed– completely flat battery or eroded bat-tery plates– fuse blown– electronic circuit board wet
– conditions are not met to allow start-ing
– insufficiently charged battery– malfunction on the starter relay
– insufficiently charged battery– faulty fuel supply
– faulty ignition
– fault in carburation
– forward speed too high compared tocutting height   (☛5.4.5)
Turn the key to «STOP»  and look forthe cause of the problem:
– check connections (☛3.4)– check connections  (☛3.4)– recharge the battery  (☛6.2.4)
– replace the fuse (10 A) (☛6.4.4)– dry using tepid air
– check that the conditions allowingstarting are met (☛5.2.a)
– recharge the battery (☛6.2.4)– contact Your Dealer
– recharge the battery (☛6.2.4)– check the level in the tank(☛5.3.3)– open the fuel stopcock  ( if pre-sent)(☛5.4.1)– check the fuel filter
– check that spark plug cap is secure-ly fitted– check that the electrodes are cleanand have the correct gap
– clean or replace the air filter– empty the fuel tank and refill withfresh fuel– check and replace the fuel filter ifnecessary
– reduce the forward speed and/orraise the cutting deck

							39ENTROUBLESHOOTING
PROBLEM LIKELY CAUSE SOLUTION
7.The motor shutsdown whilst working
8.The blades do notengage  
9.Uneven cut andpoor grass collection
10.Unusual vibra-tions while working
11.With the enginerunning, the machinedoes not move whenthe drive pedal ispressed  ( forhydrostatic drivemodels)
➤
The safety device of the electronic cir-cuit board has cut in due to:
– battery contains electrolyte but is notcharged
– the safety devices have cut in
– problems with engagement mecha-nism
– cutting deck not parallel to theground
– blade cuts badly  
– forward speed too high compared tothe height of the grass  (☛5.4.5)
– collector channel is blocked
– cutting deck is full of grass
– blades are unbalanced or loose
– bolts and screws are loose
– move the disengagement lever toposition «B»
Turn the key to «STOP»  and look forthe cause of the problem:
– recharge the battery  (☛6.2.4)
– check that the conditions allowingstarting are met  (☛5.2.b)
– contact Your Dealer
– check the tyre pressure (☛5.3.2)
– realign the cutting deck  (☛6.3.2)
– contact Your Dealer
– reduce forward speed and/or raisethe cutting deck– wait for the grass to dry
– remove the grass-catcher andempty the collector channel(☛5.4.7)
– clean the cutting deck  (☛5.4.10)
– contact Your Dealer
– check and tighten all the engine andframe bolts
– move it to position «A» (☛4.33)
If problems continue after having carried out these operations, contact your dealer.

are not collected.
3. TOWING HITCH
For towing a small trailer.
4. CLOTH COVER
Protects the machine from dust when not in use.
5. CB01 MAINTENANCE BATTERY-CHARGER
This keeps the battery in good working order when
the machine is in storage, guaranteeing an optimum
level of charge and longer battery life.
6. “MULCHING” KIT (only on some models)
It chops the grass cuttings finely and leaves them on
the lawn, instead of collecting them in the grass-
catcher.
