Daily:
1. Wipe door gasket and front of machine with damp
cloth to remove soap buildup and sand particles.
2. Leave door open overnight.
3. Wipe off outside of machine with damp cloth and
then with furniture polish.
4. Check door interlock system.
Weekly:
1. Check belt tension and tighten if necessary.
2. Check hold-down bolts and tighten if necessary.
Monthly:
Recheck belt tension.
IMPORTANT: Regular inspection and prompt
repair of all safety devices, such as door locks,
brakes, interlocks, and guards, is essential to safety
of operating personnel. Removal or bypassing of
any safety device should not be permitted.
WARNING
NEVER insert hands or objects into basket
until it has completely stopped. Doing so
could result in serious injury.
Components
Bearings: Bearing bolt torque on the UW50 should be
197 ft-lbs on the front bearing and 140 ft-lbs on the
rear. Bolts should have hardened flat washers under
the head as well as under the locknuts. Bearings have a
special interference fit to bearing housings and are not
just "off the shelf" bearings.
Lubrication: The UW50 has automatic lubrication
devices installed on the bearings. These devices have
the approximate date of replacement marked on them
(approximately 18 months from date of activation). If
lubrication is done manually, take care not to
overlubricate the bearings. Two or three shots or
strokes with a grease gun should be ample. A blown
bearing seal is more destructive than no added
lubricant. The grease installed at the factory is Shell
Alvania EP2. Any similar grease may be used.

Drain Valve: Pinch type drain valves are simple and
effective as well as dependable. Proper adjustment of
these valves is important for quiet, cool operation.
When adjusting these valves, be sure that the rubber
pinch hose passes through the center of the pinch
clamp guides. Do not stretch the rubber tight between
mounting clamps, and do not allow too much slack
between clamps. The bottom bar should be adjusted to
parallel the bottom plate of the valve. Tension should
not be sufficient to cause the solenoid to hum. Some
water may be allowed to pass through (about 2 or 3 cups
per minute) since the water level will not be affected.
NOTE: Remember, some of the water coming out
of the drain line will be due to splash out the
overflow, not leaking of the drain valve.
Spray Rinse System: The spray rinse system is
provided with a vacuum breaker (anti-syphon valve) to
prevent contamination of the water supply in case of
main failure, etc. This device requires a pressure
differential of at least 5 pounds between incoming
water and water leaving the spray system.
In cases where local water pressure is low or becomes
low periodically due to undersized supply lines, the
anti-syphon device may spit water out the top. This is
not desirable. Water service needs to be improved. The
problem is most likely to occur when only one spray
water valve is open, such as during a hot fill or a cold
fill operation.
Water Level: The water level in the washer is
controlled by one or two water level diaphragm
switches. In the case of two levels, the switch mounted
lower in the control box controls the low level. Each
switch has two adjusting screws
the unit and one offset toward the side. DO NOT adjust
the offset screw.
The center screw adjusts the water level and is
electrically "hot" when the power is on the controls, so
use an insulated screwdriver to adjust it. To raise the
water level, turn the screw clockwise (tighten); to
lower the water level, turn the screw counterclockwise
(loosen). Do not tighten or loosen this screw too far or
it will stay in the empty or full position and not
function properly.
The water level should be set when there is no load in
the washer. The level can be seen during the pause
between forward and reverse basket movement. If the
level is set too high, the water will run out the overflow
and never shut off. If the level is set too low, the switch
will not return to the empty position after the drain is
opened.
