Reversing Operation
Tumblers with the reversing option prevent the
tangling of large pieces of laundry and minimize
wrinkling. These tumblers are equipped with a second
motor and additional controls which reverse the
rotation direction of the cylinder.
Reverse Control Switch
An “on-off”switch for manual timer models, or a
touch pad for OPL Micro models is placed in the
control panel area so the operator can select the
reversing or nonreversing operation. In nonreversing
mode, the cylinder will always turn clockwise (as
viewed from the front of the tumbler). If the cylinder is
turning counterclockwise when switched to
nonreversing, it will continue for a few seconds and
then start up in the proper direction.
IMPORTANT: After any electrical maintenance is
done, make sure that the blower motor is turning
counterclockwise. Then set the reverse control
switch to “nonreversing”and note that the cylinder
turns constantly clockwise as viewed from the front
of the tumbler. If not, interchange L1 and L2
service leads to the reverse drive motor.

70283601 © Published by permission of the copyright owner –DO NOT COPY or TRANSMIT
Maintenance
Daily
Keep tumbler area clear and free from combustible
materials, gasoline, and other flammable vapors and
liquids.
Lint Removal
1. Open the lint panel or pull out lint drawer.
2. Remove all accumulated lint in the lint
compartment area. Lightly brush any lint that
may be left on the lint screen. Lint left in the lint
compartment is drawn back onto the lint screen
and will restrict proper air circulation.
3. Be sure the lint screen is not torn. If it is, replace
immediately. A torn lint screen allows lint to pass
from the tumbler to the ductwork system, thus
creating a restriction to air circulation.
4. The lint screen is designed to completely cover
the entire opening in the lint screen panel. Be
sure that it does so. Excessive gaps between the
lint screen and the lint screen panel allow lint to
pass into the ductwork system.
5. Carefully wipe any accumulated lint off of the
cabinet high limit thermostat and thermistor.
Failure to do so will allow a buildup of lint in this
area to act as an insulator, causing the tumbler to
overheat. Refer to Figure 6.
6. Replace the lint compartment panel on the
tumbler ensuring a tight fit, and lock if
applicable.
Figure 6
To reduce the risk of electric shock, fire, explosion, serious injury or death:
•Disconnect electric power to the tumbler before servicing.
•Close gas shut-off valve to gas tumbler before servicing.
•Close steam valve to steam tumbler before servicing.
•Never start the tumbler with any guards/panels removed.
•Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the tumbler is properly grounded.
W002
WARNING
To reduce the risk of serious injury, do not
open the lint panel while the tumbler is in
operation. Before cleaning the lint screen,
open tumbler door and allow cylinder to
completely stop.

Monthly
Lubrication
DO NOT lubricate bearings. All bearings are pre-
lubricated and sealed.
Lint Removal
Remove the exhaust duct from the exhaust thimble and
remove lint. If excessive lint is evident at the thimble,
further disassemble the ductwork and remove lint.
Every Three Months
Lint Removal
1. Clean the lint and any other foreign materials
from the air vents located on the motors. The
motors are air cooled and if the air vents become
clogged, the motor will overheat and the internal
thermal overload protector will cycle off.
2. Steam Models: Check the steam coils and
remove any lint buildup and/or replace air filter
in the coil fin area. This can be accomplished by
using compressed air or by fabricating a comb
that can be pulled across the fins of the coil.
3. Exhaust ducts should be periodically inspected to
ensure there has been no buildup of lint which
could obstruct the airflow.
4. Inspect the area to make sure nothing is
obstructing the flow of combustion and
ventilation air.
5. Remove front panel and clean any lint buildup.
Belt Tension
Check belt tension and adjust if needed.
Every Six Months
Overall Check
Check the tumbler over thoroughly for loose nuts,
bolts and screws, and for loose gas, electrical and/or
steam connections.
GAS CONNECTIONS: (Unions, flared tube fittings)
Check for leakage that might be caused by vibration.
Use a non-corrosive leak detection fluid. DO NOT
USE A FLAME AT ANY TIME TO CHECK FOR
GAS LEAKS.
ELECTRICAL CONNECTIONS: Electrical service
and grounding connections should be examined for
proper tightness.
To reduce the risk of electric shock, fire, explosion, serious injury or death:
•Disconnect electric power to the tumbler before servicing.
•Close gas shut-off valve to gas tumbler before servicing.
•Close steam valve to steam tumbler before servicing.
•Never start the tumbler with any guards/panels removed.
•Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the tumbler is properly grounded.
