Safety Instructions DANGER This safety symbol means danger. When you see this symbol, carefully read the instructions that follow. Failure to obey the instructions could kill or cause serious permanent injury or disability. WARNING This safety symbol means warning. When you see this symbol, carefully read the instructions that follow.
Think Safety First Toro Products are tested and certified for compliance with existing safety standards and specifications. Although hazard control and accident prevention are partially dependent upon the design and configuration of the machine, hazard control and accident prevention are also dependent upon the awareness, concern and proper training of the personnel involved in the operation, transport, maintenance, and storage of the machine.
Page 12
Think Safety First (continued) • Avoid injury to bystanders… Always clear the area of bystanders before starting or testing powered equipment. • Avoid injury due to projectiles… Always clear the area of sticks, rocks or any other debris that could be picked up and thrown by the powered equipment.
Page 13
Think Safety First (continued) – Class B fire extinguishers are for fires that involve flammable or combustible liquids such as gasoline, kerosene, grease and oil. The numerical rating for class B extinguishers indicates the approximate number of square feet of fire it can extinguish. Geometric symbol (red square).
Jacking Instructions DANGER Mechanical or hydraulic jacks may fail to support the machine and cause a serious injury. • Use jack stands to support the raised machine. • Use only mechanical or hydraulic jacks to lift the machine. 1. Park the machine on a level surface, lower the cutting units, shut off the engine, remove the key from the key switch and unplug the 48V battery disconnect.

Operator Advisories Operator advisories are automatically displayed by the InfoCenter when a machine function is prevented and additional action is required. Typically, an advisory can be eliminated with a change in machine controls by the operator. For example; if the operator attempts to drive the machine when the manual parking brake is engaged, an advisory is identified on the InfoCenter Display that the manual parking brake needs to be in disengaged.

48V Battery Disconnect CAUTION Before installing, removing or servicing components in the 48 VDC system (e.g. cutting unit motors, starter/generator), separate the 48V battery disconnect. This will prevent unexpected operation of 48V system components. The 48V battery disconnect is attached to a bracket behind the left side cover. Unplug the disconnect to make sure that 48 VDC components do not operate unexpectedly.

Electrical System Operation The eTriFlex machines use two separate electrical systems. Many of the machine functions operate on a typical 12 VDC system with a chassis ground. The electric traction motors, electric steering motor, electric cutting unit lift/lower actuators, and the electric cutting unit motors operate on an 48 VDC electrical system. The 48 VDC system is isolated (each component has its own wired ground).
Page 111
48 VDC System Operation The eTriFlex 48 VDC system includes a 48 VDC battery pack, an engine driven starter/generator (model 04580), two front traction motors, a steering input device and a steering motor, three cutting unit lift/lower actuators, three cutting unit motors, a main contactor and a traction motor contactor.
Page 112
48 VDC System Operation (continued) – model 04580), the at each front traction motor (SC5: Traction 1 and SC6: Traction 2), in the optional rear traction motor (T5: Traction 3), in the steering motor (SC7: Steering), in each lift/lower actuator (SC1: Lift/Lower 1, SC2: Lift/Lower 2, SC3: Lift/Lower 3), in each cutting unit motor (T2: Cutting Unit 1, T2: Cutting Unit 2, T3: Cutting Unit 3), along with direction from the T1: Primary controller via the CAN bus system.
Electrical System Quick Checks Testing the 12V Charging System (Model 04580) Battery Voltage Table At least 0.50 VDC over the initial battery voltage. Initial battery voltage = 12.30 VDC Battery voltage after 3 minutes charge = 12.85 VDC Difference = +0.55 VDC This is a simple test that determines if the 12V charging system is functioning.
Testing the 12V Charging System (Model 04580) (continued) Refer to the Battery Voltage Table (page 5–15) for an example of a charging system that is functioning. Checking the Interlock System Operation CAUTION The interlock system is for the operator’s protection; do not bypass any of the interlock system components.
Adjustments Adjusting the Starter/Generator Drive Belt Tension (Model 04580) For additional starter/generator service information; refer to Generator Assembly (Model 04580) (page 5–91). 1. Remove the fuel tank; refer to Removing the Fuel Tank (page 4–4). 2. Tilt the operator seat forward and remove the starter/generator pulley cover. 3.

Relays Greensmaster eTriFlex machines use a number of electrical relays. Some of the relays have four (4) terminals and some have five (5) terminals. The number of terminals the relay has determines how the relay should be tested. A tag near the wire harness relay connector can be used to identify each relay.

Contactors Two contactors are used on eTriFlex machines. Both contactors are located under the left side cover. The main contactor connects the 48V batteries to the 48V power bus for the lift/lower actuators, cutting unit motors, the optional 3WD traction motor, and the starter/generator (model 04580). The steering motor is connected to the 48V power bus at all times and is not controlled by the main contactor.
Page 184
Testing the Contactors (continued) Note: Prior to taking small resistance readings with a digital multimeter, short the meter test leads together. The meter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal resistance of the meter and test leads.
