SAFETY INSTRUCTIONS The Groundsmaster 3500-D was tested and certified by TORO for compliance with the B71.4 1999 specifications of the American National Standards Institute. Although hazard control and accident prevention partially are dependent upon the design and configuration of the machine, these factors are also dependent upon the awareness, concern, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the machine.
SAFETY INSTRUCTIONS 20. The slope angle at which the machine will tip is dependent on many factors. Among these are mowing conditions such as wet or undulating turf, speed (especially in turns), position of the cutting units (with sidewinder), tire pressure and operator experience. At side hill slope angles of 20 degrees or less the risk of a rollover is low. As the slope angle increases to a Toro recommended maximum limit of 25 degrees the risk of a rollover increases to a moderate level.

BEFORE OPERATING CAUTION If engine has been running, pressurized hot coolant can escape when radiator cap is removed and cause burns. Only open radiator cap when engine is cold. IMPORTANT: Use only types of hydraulic fluids specified. Other fluids could cause system damage. Group 1 Hydraulic Fluid (Moderate climateaverage duty) Note: The fluids within this group are interchangeable.
BEFORE OPERATING IMPORTANT: Group 1 fluids are recommended for use at typical ambient temperatures of 32 F (0 C) to 105 F (41 C). The ISO Type 46/48 fluid has been found to offer optimal performance in a wide range of temperature conditions for the average user. The Universal Tractor Fluids offer similar performance for those who prefer them, with perhaps some slight loss of efficiency at high ambient temperatures compared to the Type 46/48 fluids.
