or a hand. Wrap blades, wear gloves, and use
extreme caution when servicing.
IMPORTANT:
outdoors to help prevent sealed bearing rust or
corrosion. Water can seep into sealed bearings and
reduce component life. Bearings are sealed against dirt
and debris only.
A unit that is excessively dirty should be cleaned before
work starts. Cleaning will occasionally uncover trouble
sources. Dirt and abrasive dust reduce the efficient
work life of parts and can lead to costly replacement.

and discard. Fill fuel tank with fresh new fuel.
4.6 FILLING THE FUEL TANK
EXPLOSIVE VAPORS and FLAMMABLE
FUEL can result in serious injury or death.
Handle fuel with care. ALWAYS use an
approved fuel container.
No Smoking!
No Lighted Materials!
No Open Flame!
Allow engine to cool.
Use caution with fuel. Fuel is very flammable.

fasteners that are missing or damaged. Tighten all nuts
and bolts to their correct torque value.
4.8 GENERAL LUBRICATION
IMPORTANT:
lubrication.
Lube fitting locations are:
-each deck push arm (2)
-Hydro Idler (1)
-front ax le pivot (1)
Apply Sten Mix Hi-Temp Grease or equivalent to the
lube fittings. Order P/N: 00036700- ten pack of 14 oz.
cartridges.
When using Sten Mix Hi-Temp Grease for the first time,
all components should be thoroughly cleaned prior to
lubricating.
Apply oil at all pivot points and pin connections.
Wipe each fitting clean before and after
Add fuel to the tank as needed. See your Engine
Manual for correct type and grade of fuel.
To add fuel to the fuel tank:
