7.5 ENGINE FUEL SYSTEM
A. Filling the Fuel Tank
Fill the fuel tank at the beginning of each operating day to
within 1 inch below the filler neck. Do not overfill. Use
clean, fresh unleaded gasoline with a minimum octane
rating of 87.
B. Replacing In-Line Fuel Filter Element
-NOTE-
The fuel filter is located below the hydraulic
tank. Figure 7-5 is for illustration purposes
only.
The in-line fuel filter (Figure 7-5) should be replaced
after every 500 hours of operation or annually, whichever
occurs first.
1. Close the shut-off valve. Remove the two clamps
securing the fuel filter to the fuel hose. Remove the
fuel filter.

two clamps.
7.6 ENGINE AIR CLEANER
A. Cleaning and/or Replacing Air Cleaner
Element
For any air cleaner, the operating environment dictates
the air cleaner service periods. To make it convenient
for you we have installed an "Air Cleaner Indicator"
which is located just behind the air filter. The indicator
window will turn red when it is time to service the air
filter.
Do not service the filter unless this indicator is red.
-NOTE-
In extremely dusty conditions it may be
necessary to check the indicator daily to
prevent engine damage.
1. Snap open the two clips securing the air cleaner
cover to the air cleaner box. Remove the air
cleaner cover, clean the duck bill vent of any dust
and set the cover aside.
2. Remove the air cleaner element and inspect.
3. Clean or replace the element as recommended by
the engine manufacturer.
4. Replace the air filter cover and be sure to snap
closed the two clips.
5. Reset the air cleaner indicator by pushing the
button on the end of the indicator. The indicator
window should return to clear.
7.7 BATTERY
A. Checking Electrolyte Level and Cleaning
Battery
After every 40 hours of operation or weekly, whichever
occurs first, check the electrolyte level in the battery and
clean the battery and connections. Dirt and fluid on the
top of the battery can cause the battery to discharge.
Corrosion of the battery terminals or loose connections
will cause poor battery performance.
