ROLL OVER PROTECTIVE STRUCTURE (ROPS)
Your power unit may be equipped with a Roll-Over Protective
Structure (ROPS). This ROPS was tested in accordance with
ISO 21299 (ROPS) and ISO 3776-2 and ISO 3776-3 (Seat

Alterations to the ROPS structure are not permitted.
Always wear the seat belt.
If any part of this ROPS experiences structural damage, the entire ROPS must be replaced.
Inspect seat belt for wear or damage before use. Failure to inspect or maintain the seat belt can cause
injury or loss of life.
Operator Interlock Systems
The operator interlock systems:
prevent the engine from starting unless the selector lever is in the park position.
prevent the PTO clutch from engaging unless the operator is present on the seat and activates the PTO.
shuts off the power unit (and PTO) if the operator leaves the seat while the PTO is engaged.
prevents the power unit from moving unless the parking brake is released and the operator is pres-
ent on the seat.
Park the power unit on a level surface. Lower attachment to the ground (if attached) and turn off power unit
engine. Chock tires to prevent rolling. Ensure the operating area is free of obstacles and bystanders.
