additional information when servicing the machine.
2. Before servicing or making adjustments, lower cut-
ting units, place functional control lever in the neutral

5. Make sure all hydraulic line connectors are tight and
all hydraulic hoses and lines are in good condition be-
fore applying pressure to the hydraulic system.
6. Keepbody and handsaway from pinhole leaks in hy-
draulic linesthat eject high pressure hydraulic fluid. Use
cardboard or paper to find hydraulic leaks. Hydraulic
fluid escaping under pressure can penetrate skin and
cause injury. Fluid accidentally injected into the skin
must be surgically removed within a few hours by a doc-
tor familiar with this form of injury or gangrene may re-
sult.
7. Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be re-
lieved by stopping engine and lowering cutting units to
the ground.

11.Do not overspeed the engine by changing governor
setting. To assure safetyand accuracy, check maximum
engine speed.
12.Shut engine off before checking or adding oil to the
engine crankcase.
13.Disconnect battery before servicing the machine.

cable last. If battery voltage is required for troubleshoot-
ing or test procedures, temporarily connect the battery.
Reconnect positive battery cable first and negative
cable last.
14.Before installing, removing or working on the cutting
units, disconnect the cutting units from the electrical
power supply by separating the cutting unit power dis-
connect couplers. The couplers are located at the base
of the rollover bar on the left side of the traction unit.
Connect the couplers together before operating the ma-

face, eyes and clothing when working with a battery.
16.Battery gases can explode. Keep cigarettes, sparks
and flames away from t he battery.
17.When welding on machine, disconnect both battery
cables to prevent damage to machine electronic equip-
ment. Disconnect negative battery cable first and posi-
tive cable last. Also, disconnect the wire harness
connector from the TEC controller and the alternator
connector(s). This will prevent damage to the electrical
system of your Greensmaster.
18.At the time of manufacture, the machine conformed
to the safety standards for riding mowers. To assure op-
timum performance and continued safety certification of
