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
EC Top Dresser When It Is Operating.
Always Follow All Safety Hazard Warnings.
Work Safely, Wear The Appropriate Safety Gear.
Properly Secure The 1540 EC Top Dresser
Before Starting Any Service Procedures.
LUBRICATION
All the bearings on the 1540 EC 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.
WHEEL BEARINGS
The wheel bearings should be serviced and greased
once a year. Increase the service if the 1540 EC is being
operated in a very dusty environment. Always inspect
the wheel seals at each service interval.
ENGINE RPM SETTINGS
To ensure a stable hydraulic pressure flow to the
conveyor belt and the spinner assembly, the full throttle
engine RPM should be set at 3600 RPM. Set the speed
without the conveyor belt or the spinner assembly
operating. Allow the engine to warm up before setting
the engine RPM.
For engine RPM adjustment to the automatic
throttle control, refer to “Adjusting Automatic
Throttle Control” in the Electrical System section of
this manual.
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
EC with the hopper empty, belt cleaned, and out of
direct sunlight.
CONVEYOR BELT SCRAPER
The scraper should 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 20)
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 19 mm (3/4” 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 19 mm (3/4” inches) and check for
problems elsewhere.
