Monthly (UniLinc Control)
NOTE: Disconnect power to the washer-extractor
at its source before performing the monthly
maintenance procedures.
1. Each month OR after every 200 hours of
operation, lubricate bearings. Control will
display Lubricate Bearings Menu when service
procedure needs to be performed. (Locate the
bearing lubrication decal at the rear of the right
side of the machine, as viewed from the front of
the washer-extractor.)
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 (135 – 165 cSt at 40°C or
709 – 871 SUS at 100°F)
•
ISO VG 220 (198 – 242 cSt at 40°C or
1047 – 1283 SUS at 100°F)
•
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.
2. V-belts
a. Check V-belts for uneven wear and frayed
edges.
•
Tension Gauge.
Loosen motor mounting
bolts and slide motor along motor plate to
change belt span length. The belt tension on
35 – 125 models should be between 70 and 90
pounds (± 5 pounds). The belt tension on the
150 model should be between 130 and 150
pounds (± 5 pounds). (Set initial tension
toward the high end of this range.) The 150
model uses a swing mount motor with an
adjustable spring used for tensioning.
