. IT POINTS OUT IMPORTANT SAFETY PRECAUTIONS. IT MEANS
BE ALERT!
YOUR SAFETY IS INVOLVED.
WATCH FOR THIS SYMBOL
“ATTENTION---BECOME ALERT!”
It is your responsibility as an owner, operator, or supervisor to know and instruct everyone using this machine at the
time of initial assignment and at least annually thereafter, of the proper operation, precautions, and work hazards which
exist in the operation of the machine in accordance with OSHA regulations.
Safety Is No Accident
The following safety instructions, combined with common sense, will save your equipment from needless
damage and the operator from unnecessary exposure to personal hazard. Pay special attention to the caution
notes in the text. Review this manual at least once each year with new and/or experienced operators.
1. Read and understand the operator’s manual before operating this machine. Failure to do so is considered a
misuse of the equipment.
2. Make sure equipment is secure before operating.
3. Always keep children away from equipment when operating.
4. Make sure everyone that is not directly involved with the operation is out of the work area before beginning the
operation.
5. Make sure all safety devices, shields, and guards are in place and are functional before beginning the
operation.
6. Shut off power to adjust, service, or clean.
7. Keep hands, feet, and clothing away from moving parts. It is a good idea to remove all jewelry before starting
the operation.
8. Visually inspect the machine periodically during operation for signs of excessive vibration, loose fasteners, and

CAUTION
1. Read and understand instruction manual before operating.
2. Keep all safety shields and devices in place.
3. Make certain everyone is clear before operating machine.
4. Keep hands, feet, and clothing away from moving parts.
5. Shut off power to adjust, service, or clean.
6. Make sure machine is secured before operating.
7. When transporting, shut fuel lever off.
8. DO NOT operate machine when guards are removed.
Pre-Operating Check List:
1. Service the gas engine and gear reduction box.
2. Connect the wire harness.
3. Check all bearings for proper lubrication.
4. Check the tube for foreign material.
5. Check all belts for proper tension.
6. Tighten all setscrews.
7. Start unit and check tender belt alignment while unit is empty.
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.
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.
4
MAINTENANCE
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.
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.
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.

BOLT TORQUE
Mounting bolts and hardware
All hardware used on the Maximizer is Grade 5 unless otherwise noted. Grade 5 cap
screws are marked with three radial lines on the head. If hardware must be replaced, be
sure to replace it with hardware of equal size, strength and thread type. Refer to the
torque values chart when tightening hardware.
Important: Over tightening hardware can cause as much damage as when under
tightening. Tightening hardware beyond the recommended range can reduce its shock
load capacity.
The chart below is a guide for proper torque. Use it unless a specified torque is called
out elsewhere in the manual.
Torque is the force you apply to the wrench handle or the cheater bar, times the length of the
handle or bar.
Use a torque wrench whenever possible.
The following table shows torque in ft. lbs. for coarse thread hardware.

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. Load seed box onto frame and engage the lock down brackets. Ensure that the seed boxes are secure
before transporting.
2. Start the engine
3. Open seed box gate.
4. Open hopper seed flow gate
5. Move the toggle switch to control the start and stop of the seed flow.
7
OPERATION
HOPPER SEED FLOW GATE
CLEANOUT…
1. Close the seed box gate or hopper seed flow 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.
TRANSPORTING…
1. Lower the tube.
2. Shut off fuel supply.
3. Run engine empty of fuel.
4. 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.
5. Make sure the seed box gates are closed.
6. Make sure the seed boxes are securely seated and locked to the frame.
7. Lock conveyor in place.
8
SERVICE…
1. Check engine oil level daily.
2. Change engine oil every 25 hours.
3. Check for oil leaks daily.
4. Grease bearings every 50 hours.
5. Check bearings annually.
6. 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.
7. Belt and splice should be in good condition, check daily.
BELT REPLACEMENT INSTRUCTIONS
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.
