BLADE
To inspect the blade:
1. Tilt the mower to the right (Fig. 12), so that
the air cleaner side is up. This will help to pre-
vent fuel leakage and difficulty in starting the
engine, once procedure is finished.
2. Inspect the blade (Fig. 12.27) for damage,
cracks and excessive rust or corrosion.
3. A dull blade can be sharpened, but a blade that
is excessively worn, bent, cracked, or otherwise
damaged must be replaced. If you need to re-
move the blade for sharpening or change:
i. Remove the bolt (Fig. 12.26) with a socket
wrench. Use a wooden block to prevent
the blade from turning while attempting
to remove the bolt.
ii. Remove the washer (Fig. 12.25).
iii. Remove the blade.
To reposition the sharpened or new blade:
i. Install the blade in position.
ii. Install the washer in position.
iii. Install the bolt in position and tightethe
bolt with a torch wrench.
NOTE: A blade adaptor (Fig. 12.28) may be present, de-
pending on the lawn mower model. Make sure that you
remember to fit it in position.
After the above procedure, remove the wooden
block that was keeping the blade from turning.

mower and wash it with water. Allow it to fully dry
before putting it back in position.
NOTE: A wet bag will clog quickly.
ENGINE OIL
WARNING: Checking the level and changing the oil
should be done in solid and level ground. The engine

1. Remove the oil filler cap.
2. Wipe the oil dipstick clean.
3. Insert the oil dipstick into the oil filler neck,
without screwing it.

shown on it. If required, fill with oil to the up-
per level.
5. Place the oil dipstick in position and tighten
appropriately.
To change the oil:
NOTE: Drain the used oil while the engine is warm.
Warm oil drains quickly and completely.
WARNING: Take necessary protective measures
against hot oil to avoid any danger of burn.
1. Remove the oil filler cap.
2. Place a suitable container next to the mower
to catch the used oil.
3. Tilt the mower on its right side. The used oil
will drain through the filler neck. Allow the oil
to drain completely.
