Resumen del manual
If the snow is deep, reduce the ground speed. Always operate the snowblower with the throttle set to FAST. Using other throttle settings can reduce performance and clog the discharge chute. Traction The standard turf tires on the mid-size commercial mower power head extend beyond the width of the snowblower. This can reduce the performance of the snowblower. Narrower, AG (bar-tread) tires are recommended for best performance. Never use tire chains.
