Changing the Engine Oil
WHEN CHANGING THE OIL, ALWAYS CHANGE THE OIL FILTER. CHANGE OIL
WHEN THE ENGINE IS WARM FROM OPERATION AS THE OILS WILL FLOW
FREELY AND CARRY AWAY MORE IMPURITIES.
To change the oil use the following steps:
1. Start the engine and run until it reaches normal operat-
ing temperature.
2. Stop the engine.
3. Remove the drain plug and allow the oil to drain.
4. Remove and discard the oil filter and its sealing ring.
5. Coat the sealing ring on the filter with clean engine oil
and wipe the sealing surface on the filter mounting sur-
face to remove any dust, dirt and debris. Tighten the fil-
ter securely (follow the filter manufacturers
instructions). Do not over tighten.
6. Check the sealing ring on drain plug for any damage,
replace if necessary, wipe the plug with a clean rag, and
wipe the sealing surface on the pan and reinstall the pan
plug. Do not over tighten.
7. Fill the crankcase with oil.
8. Start the engine and check for oil leaks.
9. Stop the engine and check the oil level to insure the oil
level is at "FULL".
10. Dispose of the oil and filter in a safe manner.
Coolant Fill Procedure - Dual Fuel Engine
DAMAGE TO THE ENGINE COULD OCCUR IF NOT PROPERLY FILLED WITH COOL-
ANT. LPG FUELED ENGINES ARE MOST PRONE TO CREATING AN AIR LOCK DUR-
ING A COOLANT FILL OPERATION DUE TO THE ELECTRONIC PRESSURE
REGULATOR (EPR) BEING THE HIGHEST POINT IN THE COOLING SYSTEM. AN
EPR THAT APPEARS TO HAVE FROST FORMING ON IT IS A SIGN THAT THE
ENGINE COOLING SYSTEM CONTAINS AIR. THE APPEARANCE AND TEMPERA-
TURE OF THE EPR SHOULD BE MONITORED DURING THE COOLANT FILL OPER-
ATION. A WARM EPR IS AN INDICATION THAT THE COOLING SYSTEM IS
PROPERLY FILLED AND FUNCTIONING.
MAKE SURE ENGINE IS COOL BEFORE PERFORMING ANY MAINTENANCE
WORK.
1. Loosen the worm gear clamp on the coolant line run-
ning into the EPR as shown below and remove the hose
from the EPR. Place a rag under the hose to prevent
coolant from running onto the engine/machine.
2. Remove the radiator cap. Fill the radiator with coolant
until coolant starts to appear from the previously
removed hose at the EPR. Reinstall the hose back onto
the EPR and continue to fill radiator with coolant.
3. With the radiator cap still removed, start the engine and
run until the thermostat opens. The thermostat opens at
170° F (77° C), which can be checked using the JLG
handheld analyzer.
WHILE ENGINE IS RUNNING, AIR AND/OR STEAM MAY BE PRESENT COMING
FROM THE RADIATOR. THIS IS NORMAL.
