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 pro-
cedure. It reduces wear and makes the machine
quieter and easier to operate.
Engine Oil - Model MBV
Engine Break-In Oil
No special break-in oil is required. The engine is
serviced with 10W-30, Service Class SG oil from the
factory. The oil should be changed after the initial
engine
break-in period
of
5-8 hours.
Thereafter,
change oil
after every 50 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 without
sufficient oil supply in the crankcase.
DO NOT
operate with oil level below the
LOW
mark or
above the
FULL
mark on the dipstick.

5. If additional oil is needed, refer to
Specifications
for proper crankcase lubricant.
Fill to the FULL
mark.
IMPORTANT:
DO NOT
overfill crankcase (oil
above
FULL
level) as this
CAN
result in engine
overheating, loss of power, and possible en-
gine damage.
Changing Engine Crankcase Oil/Oil Filter
Change the engine crankcase oil
after every 50
hours
of operation and the oil filter
after every
100
hours
of operation as follows:
1. Park the mower on a
level surface with the
en gine stopped.
The engine oil should be
warm before draining. If not warm from opera-
tion, start the engine and run a few minutes to
warm the oil.
