3.Remove all 4 single blades including the washer and nuts.
4.Clean the dirt and grass from around the blade mounting area.
5.Replace all 4 blades to ensure a smooth even cut. By replacing the washer, then the half washer, then the nut securing the blade firmly,
(25 – 30Nm) repeat this for the other 3 blades.
6.Replace the blade disc and retighten the central 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: 25 – 30Nm.
If you do not have a torque wrench ask a mower service dealer to tighten the blade bolts before you use the mower.
WARNING. If the blade bolts are not tightened correctly they could loosen and/or come out and it would be possible for the blades to fly off while you are operating the mower.
7.Return the mower to the upright position.
8.Start the engine and allow the mower to run for a few minutes to check that the blade is properly fitted and that there is no undue noise or vibration. Use only the blade as recommended by the manufacturer.
