Knowing this information could help you, your family, pets or bystanders avoid injury. Use extreme caution when loading units on trailers or trucks.
Operation POTENTIAL HAZARD • Loading a unit on a trailer or truck increases the possibility of backward tip–over. WHAT CAN HAPPEN • Backward tip–over of the unit could cause serious injury or death. HOW TO AVOID THE HAZARD • Use extreme caution when operating a unit on a ramp. • Use only a single, full width ramp; DO • • • • NOT use individual ramps for each side of the unit. If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the unit.
Operation Tips for Mowing Grass Cutting Speed Fast Throttle Setting To improve cut quality, use a slower ground speed in certain conditions. For best mowing and maximum air circulation, operate the engine at “FAST.” Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
