brake, disengage the PTO, lower the rotary
broom to the ground, place all levers
including auxiliary control levers in neutral,
shut off the engine and remove the ignition
key.
2. Before starting the tractor/ rotary broom,
inspect and clean every rotating part.
3. Prior to operation, clear work area of all
objects that can be picked up and thrown.
Mark all curbs, pipes, etc. that cannot be
moved.
4. Be sure the PTO switch/lever is in OFF
position before starting engine.
5. Exercise extreme caution when operating on
or crossing a gravel drive, walks, or roads.
Stay alert for hidden hazards or traffic.
6. Do not carry passengers.
7. Keep clear of all rotating parts. Do not put
hands or feet under, or into rotary broom and
