Engine Oil - Model MBK
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. 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 “L” mark and the “F” mark).
IMPORTANT:
DO NOT
operate
engine without
a sufficient oil supply in the crankcase.
DO NOT
operate with the oil level below the
“L” mark or
above the
“F” mark on the dipstick.
5. If additional oil is needed, refer to
Specifications
for proper crankcase lubricant.
Fill up to, but
not above, the “F” mark on the dipstick.
IMPORTANT:
DO NOT
overfill the crankcase
(oil above “F” mark) as this
CAN
result in en-
gine overheating, loss of power, and possible
en gine damage.

Changing Engine Crankcase Oil/Oil Filter

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.
2. Before removing the dipstick, clean the area
around it to keep any dirt or debris out of the
en gine.
3. Remove the dipstick and oil drain plug and drain
the oil into a suitable container. Be sure to allow
ample time for complete drainage.
