DANGER
Diesel fuel is highly flammable and explosive. A fire or an explosion
from the fuel can burn you, burn other people, and damage property.
• Use caution whenever you store or handle diesel fuel.
• Do not smoke while filling the fuel tank.
• Do not fill the fuel tank while the engine is running, while the
engine is hot, or when the machine is in an enclosed area.
• Always fill the fuel tank outside and wipe up any spilled diesel
fuel before starting the engine.
• Store fuel in a clean, safety-approved container and keep the cap
in place.
• Use diesel fuel as an engine fuel only, not for any other purpose.
Checking the Fuel Lines and Connections
Note: The fuel tanks of the Groundsmaster 7210 machine are connected to a
hydraulic tee fitting (item 34 in Figure 14 ) under the operator seat. If you remove
either of the fuel tanks from the machine, ensure that the fuel is removed from
both the tanks before you disconnect any of the fuel hoses.
Check the fuel lines and connections at the scheduled maintenance intervals
recommended in the
Traction Unit Operator's Manual . Check the lines for
deterioration, damage, leaks, or loose connections. Replace the hoses, clamps,
and fittings as necessary.
Priming the Fuel System
The fuel system needs to be primed before starting the engine for the first time,
after running out of fuel or after fuel system maintenance (e.g., draining the
fuel/water separator, replacing a fuel hose). To prime the fuel system, ensure that
the fuel tank has fuel in it. Then, turn and hold the key switch in the R
UN
position
for 10 to 15 seconds which allows the fuel pump to prime the fuel system. Do not
use the engine starter motor to crank the engine in order to prime the fuel system.
Removing the Fuel Tanks
1. Park the machine on a level surface, lower the cutting deck (or implement),
shut off the engine, set the parking brake, and remove the key from the
key switch.
2. Unlatch the hood and raise it.
3. Remove the negative battery cable from the negative post of the battery.
4. Allow the engine to completely cool.
5. Raise the operator seat.
6. Use a fuel transfer pump to remove the fuel from both of the fuel tanks.
Note: Label the fuel hoses if necessary to assure correct installation.
7. Disconnect the vent hoses from the top of each fuel tank.
8. Disconnect the return hoses from the back of each fuel tank.
9. Disconnect the supply hoses from the bottom of each fuel line.
10. At the right fuel tank, loosen the 2 swell latches (item 5 in Figure 15 ) and
remove the access cover of the control panel. Position the cover away from
the fuel tank.
