For best results, the blade must be sharp. The blade can be resharpened by removing it and grinding or filing
the cutting edge keeping it as close to the original bevel as possible. It is extremely important that each
cutting edge receives an equal amount of grinding to avoid an unbalanced blade. Improper blade balance will
cause excessive vibration which will cause engine and mower damage. Be sure to carefully balance the blade
after sharpening. The blade can be tested for balance by balancing on a round shaft screwdriver. Remove
metal from heavy side until evenly balanced.
Before reassembling the blade and blade adapter to the unit, lubricate the engine crankshaft and the inner
surface of the blade adapter with light oil. Insert the key into the blade adapter and install the blade adapter to
the engine crankshaft, push the washer into the blade adapter and install the blade, see figure 14. Position
the blade with the part number facing out of the adapter. You need to line up the washer over the blade and
insert the hex bolt. Tighten the hex bolt as indicated below:

10.3 BLADE MOUNTING TORQUE
Use a 40Nm-50Nm center bolt, to ensure safe operation of your unit. ALL nuts and bolts should be checked
periodically for proper tightness.
After prolonged use, especially in sandy soil conditions, the sheet wears down and loses some of its original
shape. The cutting efficiency will be reduced and the blade will be replaced. Replace only with an approved
factory replacement blade. Possible damage resulting from the unbalanced condition of the blade is not the
responsibility of the manufacturer.
When changing the blade, you must use one of the original type marked on the blade (DAYE 263001330) (to
order the blade, please contact your local dealer or call our company, see front cover).
WARNING: Do not touch the moving blade.
10.4 ENGINE
Consult the engine manual for its maintenance instructions.
Maintain engine oil as directed in the manual that came with your unit. Read and follow the instructions
carefully.
Clean the air filter according to the instructions in the engine manual under normal conditions.
Clean every few hours under extremely dusty conditions. Engine malfunction and flooding usually indicate
that the air filter needs to be repaired.
To repair the air filter, refer to the engine manual that came with your unit.
The spark plug should be cleaned and the gap reset once a season. Spark plug replacement is
recommended at the beginning of each mowing season; Check the engine manual for the correct plug type
and spacing specifications.
Clean the motor regularly with a cloth or brush. Keep the cooling system (blower housing area) clean to allow
proper air circulation which is essential for engine performance and life. Be sure to remove all grass, dirt, and
combustible debris from the muffler area.
