THE FOLLOWING SERVICE AND
ADJUSTMENT PROCEDURES ARE
FOR QUALIFIED SERVICE LEVEL
PERSONNEL ONLY.
TO AVOID SERIOUS INJURY,
Do Not Attempt To Service any Part of the 1540
TEC Top Dresser When It Is Operating.
Always Follow All Safety Hazard Warnings.
Work Safely, Wear The Appropriate Safety
Gear.
Properly Secure The 1540 TEC Top Dresser
Before Starting Any Service Procedures.
LUBRICATION
All the bearings on the 1540 TEC Top Dresser are
sealed and require no further lubrication. Periodically
inspect the bearings on the front and rear conveyor
belt rollers and the spinner wheels for wear, damage,
or a build up of dirt or debris. Clean as required. The
tilting swivel points on the spinner assembly should be
periodically cleaned, inspected for wear or damage,
and lightly coated with machine oil for rust and moisture
protection.
INSPECTION PANEL
Access to view the inside surface of the conveyor belt
can be gained by removing the inspection panel. The
inspection panel is located on the left side of the frame.
The inspection panel can also be used to aid in the
cleaning of the top of the dirt shield.
CONVEYOR BELT CARE
The conveyor belt is a PVC composition belt with a
splice. Check the condition of the belt surface, look
for wear, cuts, and deep scrapes. Check the splice,
the splice wire should be in good condition. The splice
should not be catching on the hopper seals or the
metering gate. Replacement of the conveyor belts may
be necessary if it has been damaged, is worn, or will
no longer stay in proper alignment or adjustment.
Top dressing material can pass through the splice
causing a build-up of top dressing material on the inside
of the conveyor belt, on the conveyor pan and on the
rollers. Inspect and clean any buildup of top dressing
material from the inside surfaces of the conveyor belt.
To prolong the life of the conveyor belt, store the 1540
TEC with the hopper empty, belt cleaned, and out of
direct sunlight.
CONVEYOR BELT SCRAPER
The scraper should be adjusted to very lightly rub on
the belt. Check for a buildup of top dressing material in
and around the springs. If the plastic scraper blade is
worn and no longer touches the belt, replace the blade
to restore contact with the belt.
CONVEYOR BELT TENSION ADJUSTMENTS
(See Figure 23)
The tension on the conveyor belt must be adequate to
assure that the conveyor belt moves at the same rate
as the rear drive roller. After extended use, material
may build up on the front and rear rollers causing
undue tension on the conveyor belt or off-center
tracking problems. Clean the rollers before adjusting
tension.
Conveyor belt tension is adjustable by tightening
or loosening the belt adjusters. The adjusters are
located on both sides of the frame, near the front of
the hopper.
Before adjusting the conveyor belt for tension or
tracking problems, check the following:
● Check for a buildup of material on the inside of the
conveyor belt, idler and drive conveyor belt rollers.
● Check for broken or damaged belt tension
adjusters.
Initial adjustment is measured at the ends of the
adjuster screws. The initial setting should be 25 mm (1”
inch). If the belt still slips under load, tighten conveyor
belt adjusting screws equally at 1/4 turn intervals until
slippage stops. If belt still does not operate properly,
reset the screws to 25 mm (1” inches) and check for
problems elsewhere.
If the belt still slips under load, tighten conveyor belt
adjusting screws equally at 1/2 turn intervals until
slippage stops. If belt still does not operate properly,
reset the screws to 25 mm (1” inch) and check for
problems elsewhere.
