DANGER
Use caution when storing or handling diesel fuel.
Do not smoke while filling the fuel tank. Do not fill
fuel tank while engine is running or hot or when
machine is in an enclosed area. Always fill fuel
tank outside and clean up any spilled diesel fuel
before starting the engine. Store fuel in a clean,
safety–approved container and keep cap in
place. Use diesel fuel for the engine only; not for
any other purpose.
Check Fuel Lines and Connections
Check fuel lines and connections periodically as recom-
mended in the Operator’s Manual. Check lines for dete-
rioration, damage, leakage or loose connections.
Replace fuel lines, clamps and connections as needed.
Drain and Clean Fuel Tank
Drain and clean the fuel tank periodically as recom-
mended in the Operator’s Manual. Also, drain and clean
the fuel tank if the fuel system becomes contaminated
or if the machine is to be stored for an extended period.
To clean fuel tank, flush tank out with clean diesel fuel.
Make sure tank is free of all contaminates and debris.
Fuel Tank Removal (Fig. 7)
1. Park machine on a level surface, lower cutting unit
(or implement), stop engine, engage parking brake and
remove key from the ignition switch. Unlatch and raise
hood and operator seat.
NOTE: The fuel tanks on Groundsmaster 7200 and
7210 machines are connected to a common tee–fitting
(item 7) under the seat. If either of the fuel tanks are to
be removed from the machine, make sure that fuel is re-
moved from both tanks before disconnecting any fuel
hoses.
2. Use a fuel transfer pump to remove fuel from both
fuel tanks.
3. To remove left side fuel tank:
A. Loosen hose clamps and disconnect fuel return
and vent hoses from fittings on left side fuel tank.
B. Loosen and remove two (2) clamps (item 22) that
secure fuel tank to frame.
C. Loosen and remove cap screw (item 27), three
(3) washers (items 36, 26 and 37) and flange nut
(item 28) that secure fuel tank to frame. Locate and
retrieve spacer (item 25).
D. Loosen hose clamp and disconnect fuel supply
hose from strainer (outlet) fitting on fuel tank.
E. Lift left side fuel tank from machine.
4. To remove right side (RH) fuel tank:
A. Loosen hose clamp and disconnect vent hose
from fitting on RH fuel tank.
IMPORTANT: When removing right side fuel
tank, take care to not damage wire harness, elec-
trical components or throttle cable.
B. Loosen two (2) latches and remove control panel
access cover. Position cover away from RH fuel tank.
C. Remove five (5) flange head screws that secure
control panel to RH fuel tank. Carefully position con-
trol panel away from RH fuel tank.
D. Loosen and remove two (2) clamps (item 22) that
secure RH fuel tank to frame.
E. Loosen and remove cap screw (item 13), three
(3) washers (items 36, 26 and 37), and flange nut
(item 28) that secure RH fuel tank to frame. Locate
and retrieve spacer (item 19).
F. Loosen hose clamp and disconnect fuel supply
hose from strainer (outlet) fitting on fuel tank.
G. Lift RH fuel tank from machine.
5. If necessary, loosen hose clamp and remove strainer
(outlet) fitting from fuel tank. Clean strainer with low
pressure compressed air (50 PSI maximum pressure).
Fuel Tank Installation (Fig. 7)
1. If strainer (outlet) fitting was removed from fuel tank,
clean threads and apply Loctite 30558 thread sealant
(or equivalent) to threads of fitting. Install fitting into fuel
tank. Install and torque hose clamp from 12 to 15 in–lb
(1.4 to 1.6 N–m) to secure fitting in tank.
2. Position fuel tank to the machine.
3. Secure tank to frame with two (2) clamps (item 22),
spacer, cap screw, three (3) washers (items 36, 26 and
37) and flange nut.
4. Connect removed hoses to fuel tank fittings. Secure
hoses with hose clamps.
5. If right side fuel tank was removed, carefully position
control panel to fuel tank and secure with five (5) flange
head screws. Install control panel access cover and se-
cure with two (2) latches.
6. Lower and secure hood and operator seat. Fill fuel
tanks.
