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
MONTHLY
The two (2) 2-inch (5.08 cm) bearings that support the impellor/fan shaft
should be
lubricated. Use Shell
Alvania #2 grease or its equivalent. Impellor/fan shaft bearings
must be
lubricated.
EVERY 3 MONTHS
The four (4) 2-3/16” (5.56 cm) bearings that support the drive and idler shaft
should be
lubricated. Use Shell
Alvania #2 grease or its equivalent. Drive and idler shaft bearings
must be
lubricated. The motor bearings,
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
I.S.O. viscosity grade 460 gear oil.
