4. Repeat the process to remove the other 3 blades.
5. Clean the dirt and grass from around the blade mounting area.
6. Replace all 4 blades to ensure a smooth even cut and re-t them on the
mower in the reverse direction they were removed.
7. Lastly, secure the nuts rmly, (20-25Nm) repeating this for the other
3 blades.
8. Replace the blade mounting plate (40) with new blades attached, then
the outer ange (38), followed by the blade bolt (37). Retighten the blade
bolt tightly (50 – 59Nm).
NOTE: Use a wooden block to stop the blade from turning. The 4 blades
should be tightened fully but check to ensure they can still swing back
if they were to hit a solid object. Where required tighten the bolts with a
torque wrench, the centre disc blade bolt torque: 50 – 59Nm and the four
blades torque: 20-25Nm. If you do not have a torque wrench ask a mower
service dealer to tighten the blade bolts before you use the mower.
Blades should be replaced when they become worn and no longer cut
the grass cleanly. The performance of grass catching can also reduce if the
blades become worn. Replacement blade sets are available for purchase
from https://help.tools/ or by calling 1300 889 028.
Removing Oil
IMPORTANT: Drain the oil while the engine is still warm to ensure
rapid and complete draining.
1. With the engine o but still warm, disconnect the spark plug cover (13)
and make sure it is kept away from the spark plug (47).
