Apply the lubricant jet (1) inside the chain between
the inner and outer links, in point (2) immediately
before the engagement point on the sprocket.
Due to the centrifugal force, the lubricant, made
fluid by the solvents contained in the spray, will
expand in the working area between the pin and the
bush, ensuring perfect lubrication.
Repeat the operation by aiming the lubricant jet to
2
the central part (5) of the chain so as to lubricate the
rollers (4), and to the outer plates (6) as shown in the
1
figure.
