Spring Preload
1. Loosen the locknut.
2. Turn the spring preload adjusting nut in
direction ⓐ to increase the spring preload
and thereby harden the suspension, and in
direction ⓑ to decrease the spring preload
and thereby soften the suspension.
• Locknut ①
• Spring preload adjusting nut ②
• Special wrench ③
· A special wrench can be obtained at a
Greenworks dealer to make this adjustment.
·The spring preload setting is determined by
measuring distance A, shown in the illustration.
The shorter distance A is, the lower the spring
preload; the longer distance A is, the higher the
spring preload. With each complete turn of the
adjusting nut.
