Pre-Operating Check List
1. Hook up hydraulic hoses. Use thread
tape only on pipe thread connections.
2. Fill hydraulic oil to level with the upper
hole of the resevoir.
3. Adjust the hydraulic pressure regulator.
4. Purge air from hydraulic cylinder.
5. Service the gas engine and gear
reduction box.
6. Connect the wire harness to the solenoid
switch of the hydraulic system.
7. Check all bearings for proper lubrication.
8. Check the tube for foreign material.
9. Check all belts for proper tension.
10. Re-tighten all setscrews.
11. Start unit and check tender belt
alignment while unit is empty.
12. Do not leave electric toggle switch in the
“ON” position when not in use – will drain
battery.
BELT CARE……..
It is suggested that the unit be run every two to three days or more often if possible. This tends to keep the
tender belt alive and stops any forming of the belt to the curvature of the tube while the unit is not in use.
NOTE: Belt may deteriorate if not in use and exposed to weather conditions for any prolonged period of
time.

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.

5
MAINTENANCE
BELT SPLICING……..
A tender belt must not run out at the splice area. Run out will occur if the belt is not cut square or
splice is not installed square.
HYDRAULIC FLUID……..
Use high quality hydraulic oil. Fill oil to level with the upper hole/vent of the reservoir.
OPERATION
1. Prior to the start-up, check to see that belt is free from any objects that would bind or tear.
2. On starting for the first time, with no load on belt, apply power for a few seconds only to see that the
tender belt is well centered in the tube and on the return.
3. It should be noted at this time that too much tension on the on the tender belt will make adjustment
or training much more difficult, shorten the life of the belt, and waste power. The belt should be
tensioned tight enough so the drive roller does not slip.
IMPORTANT Fuel valve: When engine is not in use leave the fuel valve
in the OFF position to prevent fuel in the oil crankcase and or
carburetor flooding. Shut off the fuel and run the motor completely out
of fuel before transporting.
BELT TRAINING…….
It is essential that the tender belt be properly trained at all times. For this reason, all rotating parts should always be at right
angles to the tender belt.
Slight adjustment of roller shafts may be required to keep belts centered on them i.e., if the belt runs to one side of the roller –
apply more tension to this side of the belt by advancing the roller shaft on this side.
1. One or more rotating parts not in alignment.
2. Belt tensions in some part of system (usually at tail section) are below minimum recommendation.
3. Belt not loaded centrally.
When a belt is initially started, it should be jogged around the system to determine if a major run out occurs which could damage
belt and belt edges. If run out occurs at some point of the system, the reason is usually a roller out of alignment before the run
out. Alignment should be rechecked before restarting.
After the belt can be safely run without damage, final training should begin with the head roller. The belt must enter the head
roller in the center without movement from side to side. If the belt is not centered on the tail pulley, the return strand of the belt
should be observed for any section that is not centered.
After the belt is trained empty, the belt should be trained with a load. The take-up adjustments are made to prevent belt slip and
keep tensions at all points above minimums recommended when belt is operating with a load.
If slip occurs under, additional belt tension should be adjusting the take-up only enough to prevent slip from occurring under
load, and when started with a load.

PRODUCT HANDLING…..
1. Close the feed gates.
FEED GATE LEVERS
SEED FLOW CONTROL
2. Load seed box onto frame and engage the lock down brackets. Ensure that the seed boxes are secure
before transporting.
3. Open seed box gate.
4. Start the engine.
5. Position the tube over the hopper, To raise the tube, open the ball valve on the hydraulic cylinder until the
tube reaches the desired height then close the ball valve.
6. Set the flow rate with the feed gates.
7. Move the toggle switch to control the start and stop of the seed flow.
CLEANOUT…
1. Close the seed box gate before the seeding implement is full, so that the Maximizer
belts are empty of seed before transporting.
2. Run the conveyor until all the seed that is on the belts has been transferred.
3. Close the feed gate.
TRANSPORTING…
1. Lower the tube.
2. Shut off fuel supply.
3. Run engine empty of fuel.
4. DO NOT operate machine on steep slopes.
5. Make sure all the lights and reflectors that are required by local highway authorities are in place, are clean and
can be seen clearly by all traffic.
6. Make sure the seed box gates and the feed gates are closed.
7. Make sure the seed boxes are securely seated and locked to the frame.
SERVICE…
1. Check engine oil level daily.
2. Change engine oil every 25 hours.
3. Check hydraulic oil levels regularly, level should be to the vent elbow fitting.
4. Check for oil leaks daily.
5. Grease bearings every 50 hours.
6. Clean hydraulic filter annually, replace if necessary.
7. Check bearings annually.
8. Inspect the hydraulic motor shaft couplers annually.
9. Check belt tension and adjust as required. Belt tension should be just enough to drive the belt. Belt will
require 10 hours of operation to break in. Some adjustment may be required at this time.
10. Belt and splice should be in good condition, check daily.

BELT ASSEMBLY INSTRUCTIONS
At the start point, see view of head and tail assembly. Feed a cable or rope through the head
assembly down to the tail assembly. Now attach the belt to the rope/cable and use the
rope/cable to pull the belt through the tube. Make sure the rough side is up and the smooth
side is down against the inside wall of the tube.
Route both ends around head and tail roller, slide belt forward and back through tube so ends
of the belt meet at a convenient location.
Align and interlace belt and clipper lacings. Slip splice pin through clipper lacings to secure.
NOTE: The clipper lacings are connected on a metal strip that needs to be broken to allow
the belt to flex.
Tighten belt by turning adjustment nuts on head roller assembly in. Tighten evenly on each
side until belt is tight.
To train belt, see belt training instructions in this manual, page 6.
Break metal strip
between clipper
lacings to allow belt
to flex.
