maintained, and lubricated regularly and systematically.
WARNING
2. Maintenance Schedule
a. General
Figure 1 provides a suggested schedule for periodic checks and services. Refer to Section 2-2 for
lubrication requirements.
b. Maintenance Schedule Check Sheet
It is strongly recommended that the customer use a maintenance schedule check sheet. The check
sheet will provide a record of maintenance specific operation.
c. Time Intervals
The schedule is based on both hours of operation and calendar intervals. These two intervals are not
necessarily the same. The calendar period is included to make certain services are performed
regularly when equipment is being operated infrequently, or at manufacturer's recommendations.
Perform all services on a "whichever comes first" basis.
NOTE: Refer to the Perkins Diesel User's Manual for detailed engine maintenance information.
3. Engine and Related Components
See the Perkins Diesel User's Manual for Series 4.236 engines.
4. Inspection and Cleaning
Every day, check for oil, coolant, or fuel leaks. Also check for loose electrical connection. Check oil
pressure with engine running at rated RPM (2000) . Do not operate engine if oil pressure is less than 15
psi. Wipe accumulated water off from all electrical connections and instruments. Make sure that the
alternator ammeter is not discharging, which indicates that the battery is being charged.
Every week, wipe off accumulated dust, dirt and oil from the engine and generator. Check all parts for
loose connections and wear. If arcing has occurred at any electrical connections, recondition them and
securely refasten. Check engine oil and coolant levels.
Dec 31/92
Stop operations at once if a serious or possibly dangerous fault is
discovered.
