Neutral Adjustment The neutral system for this unit is a function of the transaxles. 1. Drive the unit to a flat, level surface. Engage the parking brake and disengage the PTO. 2. Without touching the ground speed control levers disengage the parking brake. If the unit moves, the neutral systems on the transaxles are not correctly adjusted. See your authorized STIHL servicing dealer. Suspension Adjustment (if equipped) The shock assemblies (A, Figure 39 - front shown, rear similar) can be adjusted to vary the amount of pre-load applied to the springs. This allows the operator to customize the ride according to operator's weight and operating conditions. Less Pre-Load: • Light operator weight • Softer, more cushioned ride • Best for relatively flat terrain More Pre-Load: • Heavy operator weight • Stiffer, more rigid ride • Better handling and greater stability on hilly terrain To Adjust the Spring Pre-Load: 1. Park the unit on a flat, level surface. Disengage the PTO, pivot the ground speed control levers out to the START/ PARK position, and stop the engine. 2. Turn the pre-load adjustment collar (B, Figure 39) to a higher notch (-) to decrease the pre-load, or to a lower notch (+) to increase the pre-load. Make sure all shocks are set to the same amount of pre-load. 32 stihlusa.com
