MAINTENANCE
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.
1. Place a drip pan or suitable container for catching the
oil. WINCO has supplied a valve on the skid frame to
hook a customer supplied 5/8” hose to conveniently
run the oil to the drip pan.
Note: There are two drain valves, one for coolant and
one for oil.
2. Drain the oil.
3. Once the oil has fully drained, close the valve.
4. Open the oil filler plug and top-off the filler pipe using
lubricant oil with the recommended oil in the
LUBRICATION section of this manual.
5. Use the dip stick to ensure the level of oil does not
exceed the “MAX” limit.

EQUIPMENT DAMAGE

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.
6. Insert the dipstick and close the oil filler cap.
7. 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.
1. Disconnect the connector for the engine cable from
the low oil pressure sensor.
2. Remove the low oil pressure sensor from the filter
mount.
3. Use an oil filter wrench to unscrew and remove the oil
filter.
4. Lightly coat the gasket on the new oil filter with engine
oil.
5. 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.
6. Warm up the engine by running it for 5 minutes and
check for any oil leaks.
7. Recheck the oil level using the dipstick.
8. Add engine oil to engine oil filler port as needed until
the level is between the maximum and minimum lines
shown on the dipstick.
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.
