8.7 DECK
The underside of the mower deck should be cleaned after each use to prevent a buildup of grass clippings,
leaves, dirt or other matter. If this debris is allowed to accumulate, it will invite rust and corrosion, and may
inhibit the collection performance. The deck may be cleaned by tilting the mower and scraping clean with a
suitable tool (make certain the batteries are removed first).
9. BLADE
The blade is made of pressed steel. It will be necessary to sharpen or replace to ensure the optimum
performance of the mower. Ensure that it is always balanced (an unbalanced blade will cause dangerous
vibrations). It is recommended to have your lawnmower serviced annually and have the blade replaced.
If the blade is removed and replaced, refit making sure that the cutting edges face in the direction of the
motor rotation. The blade bolt (2) must be torqued to 25N.m.
WARNING: For service, replace the blade as below
