CHANGING THE OIL
WINCO pipes the oil to drain to the outside for convenient
maintenance.
Winco recommends our 5W-40 fully synthetic heavy duty
engine oil to give you maximum cold weather protection
while maintaining excellent performance in warmer
weather. We have partnered with a national lubrication oil
manufacturer to give you access to Winco private branded
premium oil available at comparable prices to conventional
oils. See your dealer for additional information.
CAUTION: PERSONAL INJURY
Only change oil when the engine is not running and
is at a low temperature in order to avoid the risk of
burns.
1. Remove the oil cap to vent the engine crankcase and
allow the oil to drain more easily.
2. WINCO has supplied a 1/2” NPT threaded fitting onto
the skid frame to conveniently drain the oil.
3. Drain the oil into a drip pan or suitable container.
4. Once the oil has fully drained, close the valve.
5. Top-off through the filler port using lubricant oil
with the suitable oil table in the LUBRICATION section
of this manual.
6. Use the dip stick to ensure the level of oil does not
exceed the “MAX” limit.
7. Insert the dipstick and close the lubricant oil cap.

8. Dispose of oil in accordance to local codes. DO NOT
dispose or allow oil to seep into the ground or sewer
systems, doing so will cause environmental damage.
CHANGING OIL FILTER
The filter must be replaced when the lubricant oil is
changed.
Only use filters with a filtering degree equal to the original
filter.
CAUTION: PERSONAL INJURY
Only change oil when the engine is not running and
is at a low temperature in order to avoid the risk of
burns.
1. Use an oil filter wrench to unscrew and remove the oil
filter.
2. Lightly coat the gasket on the new oil filter with engine
oil.
3. Install the new engine oil filter manually by screwing
on new oil filter canister until sealing ring abuts the
filter head and tighten a further 3/4 turn. Do NOT use
a strap wrench or similar tool to tighten the filter
canister.
4. Warm up the engine by running it for 5 minutes and
check for any oil leaks.
5. Recheck the oil level using the dipstick.
6. Add engine oil to engine oil filler port as needed until
the level is between the maximum and minimum lines
shown on the dipstick.

WARNING
Do not fill up the new filter before it is fitted to the
support, to avoid inserting harmful impurities into the
injection system and circuit.
