Note: The lift cylinders used on the Groundsmaster 4300-D machines are very
similar. The service procedures for all lift cylinders are the same.
1. Slowly pump the cylinder shaft to remove the hydraulic fluid from the lift
cylinder into a drain pan. Plug both the ports and clean the outer surface of
the cylinder.
When you clamp the lift cylinder in a vise, clamp the clevis end of
the barrel only to prevent damage.
2. Mount the lift cylinder in a vise. Use a vise equipped with soft jaws.
