Engine oil and filter
WARNING:
If the engine has been running and is up
to operating temperature, allow the engine to cool
before changing the oil. Engine and engine oil will be
very hot, so be very careful when changing oil and
wear the appropriate protective gear to avoid being
burned or exposed to engine oil.
Check engine oil daily and after every 4 hours of operation.
Machine must be setting level when checking oil. Refer to
engine manual and maintenance schedule for oil
recommendation and capacities.
Change the engine oil and filter after the first 5 hours of
operation and per the engine manufacturer’s recommendations
after that. If mower is being operated in extremely dirty
conditions, then it is recommended oil be changed more
frequently.
IMPORTANT:
When removing the oil filter take
precautions to minimize oil spillage on the exhaust system.
A. Draining the engine oil (units equipped with oil drain
valve as shown in Fig. 4-3).
1.
Locate the oil drain valve on the lower left side of the
engine. Fig. 4-3
2.
Remove the dust cap.
3.
Locate the oil drain hose that was supplied with the
machine. Be sure to clean and clear it of debris that
might block the flow of the engine oil.
4.
Attach one end of the hose onto the oil drain valve
nipple. Make sure the hose is pushed all the way onto
the valve. Fig. 4-4
5.
Position the loose end of the hose out to the left side
of the mower so that it can drain into a suitable oil
drain container.
6.
With the hose in position, twist the valve counter-
clockwise and pull out to open the valve. Allow 10
minutes for engine oil to adequately drain.
7.
After oil is drained, close the valve by pushing in on
the valve body and twisting it clockwise.
8.
Once the valve is closed, carefully remove the oil
drain hose and clean up any spilled oil.
IMPORTANT:
All oil drips or spills
must
be cleaned
off of the exhaust system before operating the
machine.
