The little guy - Boiler cap O-ring

Please note: Do not overtighten the boiler cap, as this will potentially damage the O-ring.

• Remove the boiler cap using the group handle as per the instructions.
• When tightening the boiler cap, tighten it by hand rather than using the group handle.
• If you feel significant resistance it could indicate that the seal is sticking to the boiler mouth and might tear so try lubricating the seal by rubbing a little cooking oil onto it or use Lubrifilm Plus.
• The boiler cap should always be tightened until it hits the stop to get the optimal seal.
