CAUTION - DRIVE CHAIN SAFETY

You may be seriously injured if you attempt to install the drive chain while the pump is running. Turn OFF the engine and lock out gears and sprockets before attempting installation.

Once installed, the drive chain must be guarded to prevent personal injury or properly damage in the event the chain separates during operation. NEVER run pump with drive chain guard removed.
