MAINTENANCE
The Challenger has been designed as a low maintenance operator there-
fore almost no maintenance is required.
However, please bear the following points in mind:
In order to ensure maximum life of the Challenger, it is recommended that
the drawbar and chain be cleaned and lightly oiled (no grease) once every
six months. Also check that there is no dirt which could hinder the operation
of the system.
It is recommended that the door be serviced at least once a year - prefer-
ably before a wet season.
In the case of the courtesy light bulb fusing, please note that only a globe
with the maximum rating of 40W may be used. To order your new globe, ask
for a 40W 22d bayonet cap golfball-type globe.
To replace globe, remove the light cover by unscrewing the two holding
screws on either side of the cover. Re-insert globe and replace light cover
with the open side facing the roof. This will allow heat to dissipate without
damaging the cover.
