The roller chains on the drive units should be periodically lubricated with a roller chain lubricant.
For motor lubrication, refer to motor manufacturer’s recommendations. See the tag attached to the motors.
The oil in all gearboxes should be changed once a year, and in severe operating conditions, more frequently. Use Para-Port Door Part No. 14090090 oil or Mobil #SHC 634. While the oil is drained from the larger gearbox, remove the inspection plate opposite the final output shaft and inspect the gears for cracks, missing teeth and excessive wear.
The cam roller bearings that ride on the guide rails and the main shaft support bearings that are at the ends of tube, should be greased at least every six (6) months.
The pulleys on the counterweight system, the hinges and toggles on the inside door seals, and the pins and rollers in the portable hold-downs and outside bump rolls, should be lubricated periodically.
On the doors using counterweights; the counterweight cables should be greased with a light coating at least every six (6) months.
It
is recommended that after the
door has been in use for a short
time, that all nuts and bolts,
retainer clips, set screws,
etc., be checked and tightened
if necessary.

drive chains on the carriage

all times.
Adjustments on hold-downs should
be checked frequently to assure
that the tube is held to the
rubber sill as tight as
possible.

detergent along with a soft
brush or sponge.
All
