MAINTENANCE
Operation Sequence
1. Check drive belt for proper tension.
2. Make sure tender belt is properly tensioned.
3. Allow unit to run empty for a few minutes to flex tender belt.
4. Check tender belt for proper alignment.
5. Before shutting power off, be certain drive belt and tender belt are empty of seed.
STORAGE…………
Temporary Storage
1. Relieve tension from all belts; both v-belt and tender belt.
2. Store all belt equipment in a dry place. If equipment cannot be stored out of the weather, cover
engine and mechanical parts with waterproof material.
IMPORTANT
Prolonged Storage
1. Remove all belts and store in a cool, dark, dry place.
2. Wash tender belt thoroughly.
3. Wash tender tube both inside and out.
4. Lubricate all bearings.
5. Store in a dry shelter.
Preventative maintenance is the key to the long life of any mechanical device.
Careful and systematic inspection of the machine will result in maximum, trouble-free service.
BELT REPLACEMENT……….
To replace the belt, Remove the splice pin and hand rotate the head roller until belt has been removed.
Install appropriate belt as outlined in assembly instructions.
HEAD ASSEMBLY TAKE-UP………….
After extended use, the tender belt may stretch to the point that there is not sufficient take-up in the
head assembly to tighten it. Obtain additional take-up by cutting a 6” to 8” section from the belt. A
new splice lacing may be ordered from your dealer or from Yetter Mfg. Inc.
PERIODIC CLEAN-OUT…………….
Due to the characteristics of certain materials, residue sometimes collects between the tender belt and
the tube. Check the unit periodically for any material build up in this area. If residue appears
excessive, remove the tender belt and thoroughly wash the belt and tube. Allow belt and tube to dry
before reinstalling the belt.
LUBRICATION………
All bearings which are fitted with grease zerks should be lubricated at the conclusion of each operating
day. Before greasing the bearings, make certain the zerks are free of dirt, otherwise this will be
passed into the bearing race. If the unit will be out of service for period of time, purge the bearings.
TENDER BELT TRAINING PROCEDURE………..
A tender belt correctly installed and trained will run straight and true. The belt must run centered on all
head rollers and tail roller throughout the entire belt length.
Incorrect installation and training can result in severe edge damage, material spillage, material leakage
through the skirt rubber at the loading point, and excessive power demands. Material spillage is the
usual reason for belt carcass ruptures and pulley covers gouging and stripping, while leakage at the
skirt rubber results in excessive conveyor cover wear under the skirts.
ALIGNMENT………..
All rotating parts-head roller and tail roller must be at a 90 degree angle to the direction of belt travel,
must be level, and the midpoint of each centered on a line when properly aligned.
Alignment is checked by running a tight wire from the center of the head roller to the center of the tail
roller.
Level all rotating parts. If a part is not level, the belt will run to the lower side.
