GENERAL
In normal use little attention to maintenance is required.
8.4.1
DRUKO413/25/35
Periodically, simply observe that reel behaves correctly when extending and, retracting cable
without hesitation. Check wound cable for damage at anchor pulley and generally.
At major machine service intervals, remove reel cover and check that interior is clean and dry.
Check slip rings are clean with no signs of arcing. Check collector brushes are correctly
located on rings and, that brush spring pressure is being maintained. Replace cover making
sure that seal is located correctly all round.
8.4.1.1 Rewind Spring Mechanism
In the unlikely event of rewind spring failure, the reel will require to be removed from the
machine on which it is fixed.
With the reel on the bench, remove cover and disconnect potentiometer from engagement, tie
back spring loaded arm, disconnect wiring which passes through the reel shaft.
Turn unit over to stand on its 4 cover studs and withdraw cable from shaft.
Release socket screws, 2 at 90
°
, holding cable compartment onto shaft and withdraw
compartment, complete with cable.
The spring compartment is now exposed and, the 4 nyloc nuts and the cover may be removed.
The rewind spring will now be visible and seen to be held in a captive band. A broken spring
normally occurs close to the arbor, as this is at the point of maximum flexing. If this is seen
to be the case, the spring may be lifted out,
“BEING VERY CAREFUL TO ENSURE THAT
THE COILS REMAIN WITHIN THE CAPTIVE BAND.”
Tie the spring with soft iron wire or stout cord, as seen on the replacement spring.
Alternatively box up securely and label danger, for disposal.
Remove broken portion of spring from arbor, check for any foreign bodies, apply grease to
the arbor and fit replacement spring.
Replace spring cover making sure that seal is correctly located.
