33 If the spring is not already released, keep hold
of the pulley (3) and slowly unwind the entire
cable (4) clockwise to release the return spring
gradually.
34 Dismount the hooks [ point “B”
].
35 Remove the pulley (3), making sure that the
return spring (9) stays in place underneath the
pulley.
WARNING! Carry out this operation with
utmost care to avoid injury when the spring
suddenly unwinds, as it could slip out of
place.
36 Clean the inside of the conveyor with degreas-
ing liquid by removing any leftover dirt or
grease.
37 Cut a section of cable (4) (Ø 4.5 mm and 2.40 m
long), fit one end in the pulley hole (3) and make
a knot to stop it from slipping out.
38 Fit the other end of the cable in the conveyor
hole and secure it to the handle (5) with a knot.
39 Spray some silicone lubricant onto the spring (9)
and apply liquid grease to inside the conveyor
housing. Check that the spiral spring (10) is
securely lodged in the conveyor housing and
put the pulley (3) back in place so that the inside
end of the spring (9) is firmly lodged in the slot
on the conveyor.
40 Refit the hooks [ point “B”
].
41 Turn the pulley (3) and the cable (4) anticlock-
wise for 5 complete turns in order to load the
spring, then release the pulley carefully to wind
the entire cable onto the pulley.
42 Check that the pulley (3) rotates freely.
43 After pulling the entire length of the cable, check
that the pulley (3) is able to complete another 2-
3 turns before compressing the spring.
44 Remount the internal screen (1).
45 Remount the conveyor [ 6.1.A
].
