Adjusting the 3-way valve
The 3-way valve can be adjusted if it is too tight or too loose (liquid
loss). It is correctly adjusted when the valve handle can be turned
using one hand only.
To ease operation clean the mating faces between ball (B) and the seat
(A) of the valve.
Grease the valve every time you dismantle it for cleaning. This will
extend the service life of ball and seat.

1. Remove the screw (A), cap (B) and grease nipple (C): Twist the
cover a quarter of a turn and pull it back.
2. Remove the synthetic bearings and the protection guard.

driveshaft.
Replacing the driveshaft crossheads
