resulting from blade unbalance condition is not
the responsibility of the manufacturer.
When sharpening the blades, follow the original
angle of grind as a guide. It is extremely im-
portant that each cutting edge receives an
equal amount of grinding to prevent an unbal-
anced blade.
The blade can be tested for balance by balanc-
ing it on a round shaft screwdriver. Remove
metal from the heavy side until it balances
evenly.
Before reassembling the blade and the blade
adapter to the unit, lubricate the engine crank-
shaft 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
13. Place the blade with the side marked bot-
tom (or with part number) facing away from the
adapter. Align the blade bell support over the
blade with the tabs in the holes of the blade
and insert the hex bolt. Tighten the hex bolt to
the torque listed below:
Blade Mounting Torque
Center Bolt 450 in. lb. min., 600 in.lb. max.
To insure safe operation of your unit, ALL
nuts and bolts must be checked periodically
for correct tightness.
CAUTION: Cutting grass in sandy soil
condition causes abrasive wear to the
blades.
ENGINE
Refer to the separate engine manual for en-
gine maintenance instructions.
Maintain engine oil as instructed in the sep-
arate engine manual packed with your unit.
Read and follow instructions carefully.
Service air cleaner as instructed in the sep-
arate engine manual Clean every few hours
under extremely dusty conditions. Poor en-
gine
performance
indicates that the air cleaner should be ser-
viced. To service the air cleaner, refer to the
separate engine manual packed with your
unit.
The spark plug should be cleaned and the
gap reset once a season. Spark plug replace-
ment is recommended at the start of each
mowing season; check engine manual for cor-
rect plug type and gap specifications.
Clean the engine regularly with a cloth or
brush. Keep the cooling system (blower hous-
