Machine Maintenance: 5-6
Oil Filter
Briggs and Stratton engines use Briggs and Stratton oil filters. An equivalent or better oil
filter must be used when servicing the engine.
To replace the filter, use a proper filter wrench to remove the filter.
Clean the filter mounting base and lightly coat the gasket surface of the new filter with
engine oil. Hand tighten the filter until the gasket contacts the base, then tighten another
½ turn. Fill the engine with the correct amount of oil, run the engine and check for oil leaks
at the drain plug and oil filter gasket.
Spark Plugs
Always use the recommended spark plugs for your engine. Hotter or colder plugs, or similar
plugs that are not exact equivalents to the recommended plugs, can cause permanent
engine damage, reduce the engines useful life, and cause many other problems such as
hard starting, spark knock and run-on. Installing new spark plugs regularly is one of the
best ways to keep your engine at peak performance.
Fuel Filter
The fuel filter is located between the fuel pump and the fuel tank underneath the vehicle.
HIGH PRESSURE PUMP MAINTENANCE
Daily
Check the oil level and the condition of the oil. The oil level should be up to the center of
the sight glass on the side or rear of the pump or between the “MIN” and “MAX” lines on
the dipstick. The dipstick may be found by removing the oil cap.
Periodically
Change the oil after the initial 50 hours of operation and every 500 hours after that. It may
be necessary to replace the pump seals and check valves at 500 hours if the truckmount
has been running in high ambient temperatures.
Refer to the Pump Servicing Section starting on the following page for more information.
If the oil becomes discolored or contaminated one of the oil seals may be damaged.
Do not operate the pump if the crankcase oil has become contaminated. Do not
rotate the drive shaft without oil in the crankcase reservoir.
The pump should never be run dry. Running the pump dry will cause premature
wear on the seals, packing and plungers. Running the pump dry for a prolonged
period of time may cause damage that cannot be repaired and voids warranty.
Do not run the pump with frozen water in the manifold. If there is a risk of freezing,
freeze guard the truckmount. See the Freeze Guarding section on page 5-18 of
this manual.
