T27i Maintenance Instructions
Lubrication
57
● Use only Kohler oil lters. Aftermarket lters
may not seal properly and/or have the incor-
rect pressure relief valve for proper lubrication.
LUBRICATION
WARNING
DO NOT attempt to lubricate the machine
with the engine running. Disengage the
PTO clutch, shut o 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
The engine is serviced with Kohler PRO
®
10W-50
synthetic oil and a Kohler PRO
®
lter from the
factory. Both are rated for 300 hour oil change
intervals. A break-in engine oil change is not
required. The engine crankcase oil and the lter
must be changed after every 300 hours of opera-
tion.
NOTE: Kohler PRO
®
oil and lter are not required,
but recommended. If conventional oil and lters
are used in the tractor, the oil must be changed
after every 100 hours of operation, and the lter
must be changed after every 200 hours. See the
Specications on page 3 for details on which
oil and lters are recommended.
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 ve (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 o 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 with-
out a sucient 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 Specica-
tions on page 3 for proper crankcase lubri-
cant. Fill up to, but not above, the “F” mark
on the dipstick.
IMPORTANT: DO NOT overll the crankcase
(oil above “F” mark) as this CAN result in
engine overheating, loss of power, and pos-
sible en gine damage.
