American Dryer Corp. MLG-130DR (HSI) - Manual (Page 39)

35
Remove lint accumulation from inside the control box and at rear area behind the control box.
Impellor (fan/blower) shaft bearings should be lubricated using Shell Alvania grease NLGI 2 or its equivalent.
Generically, this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium
thickener and mineral base oil.
6 MONTHS
Inspect and remove lint accumulation in customer furnished exhaust duct work system and from dryer’s internal
exhaust ducting.
NOTE: THE ACCUMULATION OF LINT IN THE EXHAUST DUCT WORK 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
DUCT WORK. 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 shut down of
the 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 set screws), nonpermanent gas connections (i.e., unions, shut-off valves,
orifices), and grounding connections. 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).
C. LUBRICATION
The fan shaft bearings should be lubricated every three (3) months. Use Shell Alvania grease NLGI grade 2 or
its equivalent. Generically, this grease would be described as an NLGI grade 2 multipurpose industrial grease
with a lithium thickener and mineral base oil. Lubrication is necessary. The motor bearings...and under normal/
most conditions the tumbler bearings are permanently lubricated. It is physically possible to re-lubricate the
tumbler bearings if you choose to do so even though this practice may not be necessary. Use Shell Alvania
grease NLGI grade 2 or its equivalent. Generically, this grease would be described as an NLGI grade 2 multipurpose
industrial grease with a lithium thickener and mineral base oil. The tumbler bearings used in the dryer DO NOT
have a grease fitting. Provisions are made in the bearings housing for the addition of a grease fitting which can
be obtained elsewhere, or from ADC by ordering kit P/N 882159 (includes 2 fittings).
