1. Remove lint from around basket (tumbler), drive motors, and surrounding areas.

2. Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment.

3. Clean any lint accumulation in and around both the blower and drive motor casing openings.

NOTE: To prevent damage, avoid cleaning or touching the hot surface ignitor assembly.

EVERY 6 MONTHS

Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal
exhaust ducting.

NOTE: THE ACCUMULATION OF LINT IN THE EXHAUST DUCTWORK CAN

CREATE A POTENTIAL FIRE HAZARD.

NOTE: DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR.

CHECK CUSTOMER FURNISHED BACK DRAFT DAMPERS IN THE EXHAUST
DUCTWORK. INSPECT AND REMOVE ANY LINT ACCUMULATION, WHICH
CAN CAUSE THE DAMPER TO BIND OR STICK.

NOTE: A back draft damper that is sticking partially closed can result in slow drying and shutdown of

heat circuit safety switches or thermostats.

NOTE: When cleaning the dryer cabinet(s), avoid using harsh abrasives. A product intended for the

cleaning of appliances is recommended.

B. ADJUSTMENTS

7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER

Inspect bolts, nuts, screws, (bearing setscrews), grounding connections, and nonpermanent gas connections
(unions, shutoff valves, and orifices). Motor and drive belts should be examined. Cracked or seriously frayed
belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of controls and
valves. Complete operational check of ALL safety devices (door switches, lint door switch, sail switch, burner
and hi-limit thermostats).

C. LUBRICATION

The motor bearings, idler bearings, and, under normal/most conditions, the basket (tumbler) bearings are permanently
lubricated. It is physically possible to relubricate the basket (tumbler) bearings if you choose to do so even
though this practice is not necessary. Use Shell Alvania #2 grease or its equivalent. The basket (tumbler)
bearings used in the dryer DO NOT have a grease fitting. Provisions are made in the bearing housing for the
addition of a grease fitting, which can be obtained elsewhere, or from ADC by ordering kit P/N 882159 (includes
two [2] fittings).
