2. Remove front casing, see instructions on page 15.
3. Remove the hydraulic can table, see “3.2 Removing the can table during service”.

If the rail is too low the plastic hooks do not reach the piston rods when the solenoid is
activated.

NOTE!: The solenoids must be in straight line in order to hit the plastic hooks!
10. Fasten the rail with screw in place.
