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 drawer 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 re-lubricate the basket (tumbler) bearings if you choose to do so even
though this practice is not necessary. Use Shell Alvania #2 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.
The impellor (fan) shaft bearings should be lubricated every 3 months.
