DRAINING AND REFILLING THE OIL SYSTEM - Always drain the complete system. Draining when the
oil is hot will help to prevent varnish deposits and carry away impurities see Figure 1-3, for hardware
details.
1. Be sure the unit is completely off and that no air pressure is in the oil reservoir.
2. Disconnect, lockout and tagout the power supply to the starter.
3. Thoroughly drain oil system while system is hot:
Open the drain valve at the bottom of the oil sump and remove the single drain plug at the
bottom of the oil core tank. Once the oil has been drained, reinstall the drain plug and close the
drain valve.
Make sure to provide a suitable pan to catch the 0.65 gallon oil charge. Reinstall the drain plug
after drainage.
If the drained oil and/or oil filter element is contaminated, discontinue this procedure and follow
instead the "Lubricant Change Procedure" in this Section.
4. Replace both used oil filter and air/oil separator element with new ones.
Remove each spin-on element.
Clean each gasket face of the filter body.
Coat each new element gasket with clean lubricant used in the unit
Screw each new element on the filter body and tighten by hand. Tighten 1/2 turn more after
gasket makes contact. DO NOT OVERTIGHTEN ELEMENT.
5. Wipe away all dirt around the oil filler plug.
6. Remove the oil filler plug and add oil as required to return the oil level to the full marker on the gauge.
7. Install the oil filler plug and operate the unit for about a minute allowing oil to fill all areas of the
system. Check for leaks.
8. Shut down unit, allowing the oil to settle, and be certain all pressure is relieved.
9. Add oil, if necessary, to bring level to "FULL."
Use only CLEAN containers and funnels so no dirt enters the reservoir. Provide for clean storage of oils.
Changing the oil will be of little benefit if done in a careless manner.
Use only the replacement element shown on the filter tag or refer to the parts list
for the part number.
Excessive oil carry-over can damage equipment. Never fill oil reservoir above
the "FULL" marker.
Improper oil filter maintenance will cause damage to equipment. Replace filter
element every 1000 hours of operation. More frequent replacement could be
required depending on operating conditions. A filter element left in service too
long may damage equipment.
