Page 10: Safety Instructions
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.
Page 11: Think Safety First
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).
Page 14: Jacking Instructions
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.

Page 23: Identifying The Fastener
Toro recommends replacing fasteners with a locking feature once they have been removed because the effectiveness of the locking feature diminishes with each reuse. If it is necessary to reuse a fastener with a locking feature; apply a thread locking compound (Loctite for example) to the fastener during installation.

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.

Page 178: Relays
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.

Page 183: Contactors
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.

Page 284 Removing the Reel Assembly (continued) B. Insert a long-handled pry bar (3/8 x 12 inch with screwdriver handle recommended) through the bottom of the cutting unit. The pry bar should pass between the top of the reel shaft and the backs of the reel blades so that the reel will not move.
Page 285 Note: Reels+™ is a line of replacement reels (with the seals and bearings pre-assembled) that arrive ready for installation into the cutting unit. Contact your local Toro Distributor for additional information. 2. Press the bearings and slide the seals from the reel shaft. Discard the seals and inspect the reel bearings to insure that they spin freely and have a minimal amount of axial play.
Page 286 Inspecting the Reel Assembly (continued) IMPORTANT The seal must be installed with the flocked side of the seal toward the bearing. 4. Slide the new flocked seals and press the bearings onto the reel shaft until they contact the shoulder of the reel shaft. Note: The reel nut on the left end of the cutting reel has a black finish and has left-hand threads.
Page 287 Installing the Reel Assembly (continued) IMPORTANT To avoid grinding the reel, do not contact the cutting edge of any blade with the pry bar as this may damage the cutting edge and/or cause a high blade. g285246 Figure 140 Reel nut (right end shown) Weld side of reel support plate Reel shaft Pry bar...
