4. For electric heat models only, inspect heating elements for ex-
cess debris by rotating basket to view them through its perfo-
rations. Remove drain valve hose to access and clear debris
with pliers. Replace element(s) if necessary.
NOTE: Lint buildup may take several months to oc-
cur. Inspect heating elements a minimum of every 6
months.
5.
For 80 and 100 pound [36.3 and 45.4 kg] capacity models
only
: Lubricate the barings each month or after every 200
hours of operation. Visually inspect grease line for air pock-
ets, purging air pockets as necessary.
The grease must have the following characteristics:
• NLGI Grade 2
• Lithium-based
• Water-insoluble
• Anti-rusting
• Anti-oxidizing
• Mechanically stable
The grease must have adequate base oil viscosity with one of the
following ratings:
• ISO VG 150 (709–871 SUS at 100°F [135–165 cSt at
40°C])
• ISO VG 220 (1047–1283 SUS at 100°F [198–242 cSt at
40°C])
• An SAE 40 rating is also acceptable as long as the cSt or
SUS values are within the specified ranges.
Pump the grease gun slowly, permitting only 2 strokes.
NOTE: Do not pump the grease gun until grease
comes out of the bearing housing. This can result in
over lubrication, causing damage to bearings and
seals.
Yearly
NOTE: Disconnect power to the machine at its source
before performing maintenance procedures.
1. Remove the front panel(s) and rear access panels and inspect
all hose, drain, and overflow connections/clamps for leaks. In-
spect all hoses for visible signs of deterioration. Replace as
necessary.
2. Inspect the belt for unusual wear, frayed edges, and improper
belt tension, replacing belts and/or adjusting tensioning ele-
ments as necessary.
NOTE: Belts must not be twisted and must be prop-
erly seated on pulleys. Belt must be centered on
basket pulley within .04 inches [1 mm].
a. Use the following procedures to determine if belt(s) re-
quire replacement or adjustment. Call a qualified service
technician in either case.
NOTE: Basket pulley must be rotated three (3)
full turns before assessing belt tension after ev-
ery adjustment.
