B. ADJUSTMENTS
7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER
Inspect bolts, nuts, screws (bearing setscrews), grounding connections, and nonpermanent gas connections
(i.e., unions, shutoff valves, and orifices). Fan (impellor) V-belts, along with the motor and drive chains should
be examined and replaced if necessary. Tighten loose V-belts when necessary. Complete operational check of
controls and valves. Complete operational check of ALL safety devices (i.e., door switches, lint drawer switch,
sail switch, burner, and hi-limit thermostats).
30 DAYS AFTER INSTALLATION
SHUT OFF ALL POWER TO THE DRYER. Verify that the electrical connections to the motor contactors
and overloads are tight. This is done to accommodate the compression of the wires over time.
C. LUBRICATION

Alvania #2 grease or its equivalent. Impellor/fan shaft bearings must be lubricated.

The four (4) 2-3/16” (5.56 cm) bearings that support the drive and idler shaft should be lubricated. Use Shell

idler bearings, and under normal/most conditions the basket (tumbler) bearings are required to be lubricated.
EVERY 6 MONTHS
The oil in the gear reducers must be changed every 6 months. Each reducer takes 1-1/2 quarts (1.4 liters) of
