Check Fuel Level
1. At end of each work day, fill fuel tank. Add fuel through fuel
fill tube (1, Figure 21). When working at a temperature of
0°C (32°F) or higher, use ASTM No. 2-D or its equivalent.
At temper
atures below 0°C (32°F) use ASTM No. 1-D or its
equivalent.
2. Make sure that fuel fill hose is grounded to the ex
cavator
before fueling begins.
3. Check the amount of fuel in the tank by observing the fuel
ta
nk sight gauge (2, Figure 21).
NOTE: See "Fluid Ca
pacities" on page 4-9 for capacity.
4. The excavator may be equipped with the optional battery
operated fuel fill pump. The pump ass
embly is in the
hydraulic pump compartment. Put the suction hose of the
pump into the fuel resupply tank. Turn the switch in the
pump compartment "ON", and the fuel will be pumped into
the excavator fuel tank.
NOTE: See "Fue
l T
ransfer Pump (Optional)" on
page 4-75, for further information.
5. Do not overfill the tank.
6. Securely tighten cap after fueling.
NOTE: If br
eathe
r holes (3, Figure 22) in cap are
clogged, a vacuum may form in the tank
preventing proper fuel flow to engine. Keep
holes in fuel cap clean.
Check for Leaks in Fuel System
1. Perform an inspection of the engine compartment to verify
that fuel system is not leaking. If any is noted, determine
the source of the leak and repair.
