Found these 'instructions' while browsing the webEasy 7-step guide to changing your own blades
The first challenge is gaining access to the blades of the mower that normally remain hidden from oneοΏ½s view. One has to lift the body of the machine-upto see the blades to be able to unscrew the nuts and bolts and remove the blades.
Action the following step-by-step guide prior to
unscrewing your blades:
1.Remove spark plug from the body of the lawn mower.
This disables the machine from starting-up during the process
2 .Empty the fuel tank.
This avoids spillage during the changing of lawn mower blades
3.;
Try lifting the body of the lawn mower using the limb of a tree and a rope.
This enables the machine to be at
a height suitable for you to work beneath, enabling easier access to your blades
4.;Wedge a piece of wood in between the blade and the body so as to safeguard and fasten your work area.
This avoids the risk of blades moving in the opposite direction when applying force. This will fix the blade you are working on to stay in a particular position.
5.Use a wrench.
Turn the nuts anticlockwise to remove the blades
6.;Once you have
opened the blades, replace them with new blades
7. Tighten the
screws through clockwise movement of the wrench. Do not forget to use the wood-tip once again to allow you to tighten the blades.
Tighten the
screws A SECOND TIME
