Adjustments
Air Flow Switch
The air flow switch on the 32DG model is set at the 
factory for proper operation.
IMPORTANT: Air flow switch vane must remain 
closed during operation. If it opens and closes 
during the drying cycle, this indicates insufficient 
air flow through the tumbler. If switch remains 
open, or pops open and closed during the cycle, the 
heating system will shut off. The cylinder and fan 
will continue to operate even though the air flow 
switch is malfunctioning.
Refer to the Parts and Service manual for information 
on adjusting the air flow switch.
NOTE: Air flow switch operation may be affected 
by a clogged lint screen, lack of make-up air, or 
obstructions in the customer installed main or 
collector ducts. These conditions must be checked 
and corrected before attempting to adjust the air 
flow switch.
Cylinder Door Switch and Strike
The door switch should be adjusted so the cylinder 
stops when door is opened two inches (5.08 cm), plus 
or minus 1/4 inch (6.35 mm). This switch is a 
normally open switch and is closed when the door is 
closed.
1. Close door and start tumbler, slowly open loading 
door. Cylinder and heat system should shut off 
when door is open two inches plus or minus 1/4 
inch.
2. Slowly close loading door. When door is two 
inches (5.08 cm) from being fully closed, the tab 
on the door should contact the switch plunger and 
depress it enough to close the switch with an 
audible “click.” Refer to Figure 13.
3. If tab does not depress the switch plunger enough 
to operate the switch, bend tab on loading door 
INWARD towards machine (away from hinge) 
and repeat steps 1 and 2.
4. If the tab on the door operates the switch before 
the two inch distance, bend tab on loading door 
OUTWARD away from machine (towards the 
hinge) and repeat steps 1 and 2.
Cylinder Door Strike
Refer to Figure 14.
The door strike must be adjusted to have sufficient 
tension to hold loading door closed against force of 
load tumbling against it. Proper adjustment is when 
eight to 15 pounds (35.6N to 80N) pull is required to 
open door.
To adjust, open door, loosen jamnut and turn door 
strike screw in or out as required. Retighten jamnut.
Drive V-Belt
The drive V-belt tension is automatically set by a 
spring loaded idler system. There is no adjustment.
1. Remove belt guard front panel from rear of 
tumbler.
2. The belt should show no signs of excess wear or 
cracking. If it does, replace with a genuine 
service replacement.
3. Ensure that spring loaded idler arm is free to 
move by squeezing the belt together. Idler arm 
should move freely with moderate 
(approximately 20 pounds, 9.08 kg) of spring 
force.
4. Replace the belt guard. Failure to do so will result 
in the tumbler not starting.
To avoid serious injury, disconnect power 
to the tumbler before performing this 
operation.
