LUBRICATION
WARNING
DO NOT attempt to lubricate the machine
with the engine running. Disengage the
PTO clutch, shut off the machine, and re-
move the ignition key.
Proper lubrication is an important maintenance
procedure. It reduces wear and makes the
machine quieter and easier to operate.
Engine Oil
Engine Break-In Oil
No special break-in oil is required. The engine is
serviced with 10W-30, Service Class SJ oil from
the factory. Change the oil after the initial engine
break-in period
of
5 hours.
Thereafter, change oil
after every 100 hours
of operation.
Checking Engine Crankcase Oil Level
Check the engine crankcase oil level before use
and
after each 8 hours
of continuous operation.
IMPORTANT:
The importance of checking and
maintaining the proper crankcase oil level cannot
be overemphasized. Check the oil level
BEFORE
EACH USE.
1. Park the mower on a
level surface with the
en gine stopped.
Also, make sure the engine
is cool and oil has had time to drain into the
sump [allow
at least five (5) minutes
after
stopping the engine].
IMPORTANT: NEVER
check or add oil with
the engine running.
2. Before removing the dipstick, clean the area
around the dipstick to keep any dirt or debris
out of the engine.
3. Remove the dipstick, wipe off with a clean rag,
then reinsert the dipstick into the tube and
press all the way down.
4. Remove the dipstick again and check the oil
lev el on the dipstick. The oil level should be
within the “Operating Range” on the dipstick
(between the
LOW
mark and the
FULL
mark).
IMPORTANT: DO NOT
operate engine with-
out a sufficient oil supply in the crankcase.
DO NOT
operate with the oil level below the
LOW
mark or above the
FULL
mark on the
dipstick.
5. If additional oil is needed, refer to
Specifica
-
tions on page 3
for proper crankcase lubri-
cant.
Fill up to, but not above, the FULL
mark on the dipstick.
IMPORTANT: DO NOT
overfill the crankcase
(oil above
FULL
mark) as this
CAN
result in
engine overheating, loss of power, and pos-
sible engine damage.
