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. 

(Fig. 25)

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 with the “star” away from the 
engine. Refer to 

Fig. 25

. 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 must be tightened to 35 - 45 Nm torque. 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, must use the original type 
marked on the blade (MAKITA 263001451) (for order the 
blade, pls. contact your local dealer or call our company).

WARNING: 

Do not touch rotating blade.

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. 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.
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.

NOTE:

- When storing any type of power equipment in an 

unventilated or material storage shed;

- Care should be taken to rust-proof the equipment. 

Using a light oil or silicone, coat the equipment, 
especially cables and all moving parts.

- Be careful not to bend or kink cables.
- If the starter rope becomes disconnected from rope 

guide on handle, disconnect and ground the spark plug 
wire, Depress the blade control handle and pull the 
starter rope out from engine slowly. Slip the starter rope 
into the rope guide bolt on handle.

Transport

Turn the engine off and allow the engine to cool down. 
Then disconnect the spark plug wire and empty the fuel 
tank according to the instructions in the engine manual. 
Ensure not to bend or damage the cutter when pushing 
the lawn mower over obstacles.
