Operation Think Safety First Please carefully read all the safety instructions on pages 2–8 and view the training video. Following these instructions could help you or bystanders avoid injury. Choke To start engine, close carburetor choke by moving the control lever forward to the ON position. After engine starts, regulate choke to keep engine running smoothly. As soon as possible, open the choke by moving the control lever rearward to the OFF position. A warm engine requires little or no choking.
Operation Attachment tilt lever Flow divider control To tilt attachment forward, slowly push the attachment tilt lever forward. Move flow divider control to twelve–o’clock position (normal operating position) for no flow division. When moving control to nine–o’clock position, flow is diverted to the attachments and less is available to the wheels and loader arms. This allows for greater concentration of power where it’s needed most.
Operation Starting and Stopping Engine Starting 1. Stand on platform. 2. Move the auxiliary hydraulics valve lever to neutral. POTENTIAL HAZARD • Attachment may move during starting WHAT CAN HAPPEN • Operator or bystander may be injured by attachment HOW TO AVOID THE HAZARD • Make sure auxiliary hydraulic lever is in neutral position during engine starting. 3. Move the throttle control midway between “SLOW” and “FAST” positions before starting a cold engine. 4.
Operation Driving Forward or Backward Stopping the Machine The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the “FAST” position for best performance. To stop the machine, move the traction control levers to neutral, lower loader arms to the ground, and turn the ignition key to “OFF” to stop the engine. Remember to remove the key from the key switch. Note: Throttle position can be utilized to operate at slower speeds. Forward 1.
Operation Moving A Non Functioning Machine IMPORTANT: Never tow the machine because hydraulic damage may occur. To Move the Machine 1. Turn the ignition key to “OFF” to stop the engine. 2. Lift entire machine off the ground and move machine. Using Cylinder Locks IMPORTANT: Normal maintenance should be completed with loader arms lowered. If maintenance or repair requires the loader arms raised, use the cylinder locks. POTENTIAL HAZARD • Loader arms may lower when in the raised position.
Operation Attachments 7. Move the auxiliary hydraulics lever to the forward, backward and back to neutral position to relieve hydraulic pressure at the hydraulic couplers. 8. Remove protective covers from hydraulic couplers on machine. Connect covers together to prevent contamination during operation. 9. Slide collar back on hydraulic coupler and connect attachment couplers to machine couplers. Connecting IMPORTANT: Use only Toro approved attachments.
