Oil Change Interval:
Detailed in manual, typically based on operating hours or mileage, and specific to two-stroke pre-mix or oil injection system.
Clutch Inspection:
Regular inspection of drive and driven clutches for belt wear, sheave condition, and roller wear is critical.
Track Tension Adjustment:
Periodic adjustment of track tension to prevent excessive wear or slippage.
Engine Oil Type:
Two-stroke engine oil, specifically for air-cooled or liquid-cooled engines as applicable. Type and grade (e.g., API TC, JASO FD) specified in the manual.
