CHAIN DRIVE
Nonreversing Models
Refer to Figure 20.
Proper tension is when the belt can be depressed
approximately 1/2 inch (1.27 cm) by applying light
thumb pressure at a point midway between the cylinder
sprocket and the idler sprocket.
IMPORTANT: After a tumbler has been in operation
over an extended period of time, a “HIGH POINT”
will develop on the cylinder drive sprocket through
use and wear. Turn the sprocket manually with drive
chain in place until this “high point” is at the top
center. The “high point” can be found by noticing
increased chain tension while slowly rotating the
cylinder sprocket manually.
1. Remove guard from rear of tumbler.
2. To adjust chain tension, loosen acorn nut holding
idler sprocket to housing.
3. Move idler sprocket left or right until proper chain
tension is reached, then retighten the acorn nut.
4. Replace the guard on rear of tumbler.
BELT DRIVE
Nonreversing Models
Refer to Figure 21.
Proper tension is when the drive V-belt can be depressed
approximately 1/2 inch (1.27 cm) by applying light
thumb pressure at a point midway between the sheave
and motor pulley.
1. Remove guard from rear of tumbler.
2. To adjust belt tension, loosen idler housing bolts
holding idler housing assembly to the housing
support.
3. Position housing assembly by turning adjusting bolt
until proper belt tension is reached, then retighten
idler housing bolts.
4. Replace the guard on rear of tumbler.
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the tumbler before servicing.
