Maintenance—General
MAINTENANCE
1. CLEAN LINT SCREEN DAILY. Remove lint before
starting day’s operation. A clean lint screen will increase the
efficiency of the dryer, as the moisture-laden air will be
exhausted more quickly.
2. CLEAN BASKET AND SWEEPSHEETS. Clean
periodically and/or as often as required. The basket and
sweep sheets are easily accessible by removing the front
panel of the dryer.
3. PULLEYS AND BELTS. Keep belts clean. Oil and dirt
will shorten the useful life of the belt. Never allow a belt to
run against the belt guard. Check periodically for alignment.
Pulley shafts must be parallel and the grooves must be
aligned. Check and re-tighten pulley set screws periodically.
Check belt tension periodically. Lower motor to increase
tension by adjusting the nuts fastening the motor plate to the
rod connected to the motor mounting bracket on the back at
the dryer. The fan belt is adjusted by removing links in the
belt.
4. ELECTRIC MOTORS. Keep motors clean and dry.
Motors having ball bearings are packed with sufficient
grease for approximately five years of normal operation.
After five years, the bearings and housing should be cleaned
thoroughly. Repack each bearing and the cavity in back of
the bearing on-third full with Chevron grease no. SR1-2.
Motors having wool packed sleeve bearings are oiled at the
factory for one year of normal operation. After one year, add
annually one-half teaspoon of electric motor oil or
S.A.E.#10 to each bearing. For 24 hour per day operation,
add one teaspoon of oil annually.
If motors overheat, check voltage and wiring. Low voltage,
inadequate wiring, and loose connections are the main cause
of motor failure.
5. STEAM HEATED UNITS. Keep steam coils clean.
Check periodically and clean often, as required. Remove lint
and dirt build-up from fins. Dirty fins decrease the efficiency
of steam heated units.
