For your convenience, write the product model and serial numbers in the space below. Warning Model No: Engine exhaust contains carbon monoxide, an odorless, deadly poison that can kill you. Serial No. Do not run the engine indoors or in an enclosed area. Read this manual carefully to learn how to operate and maintain your product correctly. Reading this manual will help you and others avoid personal injury and damage to the product.
• Do not over-load the attachment and always keep the load level when raising the loader arms. Logs, boards, and other items could roll down the loader arms, injuring you. Operation • Never run an engine in an enclosed area. • Only operate in good light, keeping away from holes and hidden hazards. • Never jerk the controls; use a steady motion. • Be sure all drives are in neutral and parking brake is engaged before starting the engine. Only start the engine from the operator’s position.
• If any maintenance or repair requires the loader arms to be in the raised position, secure the arms in the raised position with the hydraulic cylinder lock. • Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction. • Avoid starting or stopping on a slope. If the traction unit loses traction, proceed slowly, straight down the slope. • Secure the loader arm valve with the loader valve lock anytime you need to stop the machine with the loader arms raised.

Add the correct amount of gas stabilizer/conditioner to the gas. Danger Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold.
Use 10W-30 detergent, diesel engine oil (API service CH-4 or higher). 1 1. Remove the attachment, if one is installed; refer to Removing an Attachment, page 21. 2 m–4745 2.

Moving a Non-functioning Traction Unit Note: A warm or hot engine may not require choking. 4. Turn the ignition key to the start position. When the engines starts, release the key. Important Do not tow or pull the traction unit without first opening the tow valves, or the hydraulic system will be damaged Important Do not engage the starter for more than 10 seconds at a time. If the engine fails to start, allow a 30 second cool-down period between attempts.
Connecting an Attachment 5. Lower the cylinder lock over the cylinder rod and secure it with the clevis pin and hairpin cotter (Fig. 15). Important Use only Toro-approved attachments. Attachments can change the stability and the operating characteristics of the traction unit. The warranty of the traction unit may be voided if used with unapproved attachments. 1 3 Important Before installing the attachment, ensure that the mount plates are free of any dirt or debris and that the pins rotate freely.
4. Remove the protective covers from the hydraulic couplers on the traction unit. Warning 5. Ensure that all foreign matter is cleaned from the hydraulic connectors. If you do not fully seat the quick attach pins through the attachment mount plate, the attachment could fall off of the traction unit, crushing you or bystanders. 6. Push the attachment male connector into the female connector on the traction unit.
