2013 Yamaha YFMS50DE/YFMS50DHE/YFMSSOPE/YFMSSOPHE / Grizzly 550 - Essential ATV Owner's Manual for Safety, Maintenance & Operation

Yamaha Grizzly 550 Owner's Manual - 2013 Edition

This professional technical guide provides the necessary operational and maintenance framework for the Yamaha 550 series utility vehicles. It features a critical unique maintenance insight regarding the high-pressure nitrogen gas rear shock absorber assemblies; these units require exclusive dealer servicing as unauthorized tampering or exposure to high heat can lead to cylinder explosion, a factor vital for maintaining fleet safety and long-term vehicle uptime.

Technical Depth & Factory Benchmarks

System architecture is defined by integrated electronic monitoring and mechanical protection limits. The vehicle utilizes a self-diagnosis device that generates specific numerical error codes on the multi-function display to identify electrical circuit malfunctions. The "On-Command" drive system includes a safety speed limiter that restricts travel to 35 km/h (22 mi/h) when the differential is locked, though an "Override" switch allows for temporary full engine power access during forward maneuvers.

Visual Navigation Aids

• Chassis & Controls: Detailed left and right views with 20+ identified component locations (3-1).
• Cockpit Layout: Multi-function display mapping including fuel meters, clock, and hour meter (4-5).
• Bodywork Access: Panel removal sequences for maintenance points A through H (8-10).
• Safety Labeling: 12-point specification label location map for rapid field reference (1-1).
