10.2 Cutting blade
CAUTION: Be sure to disconnect and ground the spark plug wire before
working on the cutting blade to prevent accidental engine starting. Protect
hands by using heavy gloves or a rag to grasp the cutting blades.
Tip mower : When the mower is tipped over onto its side, please take care that the air cleaner
is on the top side . Remove the hex bolt and washer which hold the blade and blade adapter
to the engine crankshaft. Remove the blade and adapter from the crankshaft.
WARNING: Periodically inspect the blade adapter for cracks, especially if
you strike a foreign object. Replace when necessary.
For best results your blade should be sharp. The blade may be resharpened by removing it
and either grinding or filing the cutting edge keeping as close to the original bevel as possible.
It is extremely important that each cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. Improper blade balance will result in excessive vibration
causing eventual damage to the engine and mower. Be sure to carefully balance blade after
sharpening. The blade can be tested for balance by balancing it on a round shaft screwdriver.
Remove metal from the heavy side until it balances evenly.
Fig. 11
Before reassembling the blade and the blade adapter to the unit, lubricate the engine
crankshaft and the inner surface of the blade adapter with light oil. Install the blade adapter on
the crankshaft with the "star" away from the engine. Refer to figure 11. Place the blade with
the part number facing away from the adapter. Align the washer over the blade and insert the
hex bolt. Tighten the hex bolt to the torque listed below:
10.3 Blade mounting torque
Centre Bolt 40Nm.min, 54Nm.max. To insure safe operation of your unit. ALL nuts and bolts
must be checked periodically for correct tightness.
After prolonged use, especially in sandy soil conditions, the blade will become worn and lose
some of the original shape. Cutting efficiently will be reduced and the blade should be
replaced. Replace with an approved factory replacement blade only. Possible damage
resulting from blade unbalance condition is not the responsibility of the manufacturer.
