How long it lasts
Replace it when the blades or bolts are worn or damaged, in sets so the cutter stays balanced, Masport says; check them before each use and whenever the mower hits something or starts to vibrate.
After replacing: No reset needed.
How to change the 783310 blade
Watch the guide or follow the steps.
- 1Stop the engine and wait for the blade to stop, then remove the spark plug lead and keep it away from the plug. Wear protective gloves.
- 2Drain the fuel, then tilt the mower with the spark plug uppermost, as the engine book says.
- 3Undo the blade centre bolt and take the blade carrier (disc) off the mower, noting where each part goes.
- 4Undo the tip mounting bolts and fit the new blades with the new bolts, washers and nuts from the set. Replace all the blades on the carrier together.
- 5Refit the carrier so its slots sit over the lugs and the drive plate; replace the mounting bolts if they are worn. Tighten the tip bolts to 20-25 Nm and the centre bolt to 45-50 Nm.
