MONTHLY MAINTENANCE
Check the chain tension, without any goods on the turntable, by
pushing the chain with your hand (1). If there is more than ± 8 mm
space then you must tighten the chain. Release the motor housing
on the base unit. Loosen the four screws on the gear box, one turn
is normally enough. Tighten the chain by adjusting the large bolt
located in front of the gearbox (2). Check that the space of the
chain is about ± 3 mm (do not tighten too hard). Fasten all the bolts
thoroughly.
Check the brake disc located under the lower cone (1) of the file
spool by first releasing the locking ring (2) and then lifting off the
cone. If the thickness of the brake disc is less than 7 mm replace it.
Check the two cogbelts on the prestretch unit. Start by moving the
lever
down, left and screw the lever free. Let the film spool remain in
place. Release the housing (three screws). Check whether or not
the cogbelts need to be replaced or tightened. Adjust the cogbelt
tension by easing the four screws holding the motor and then
slightly moving the motor. Apply the screws firmly again and check
that the cogbelts are lightly tightened on both sides of the
cogwheel.
