Rear Roller Air System
Maintenance
IMPORTANT
Do not at any time operate the Rear Roller Air System
Air Pressure below 15psi. The Air Springs must
maintain a minimum Air Pressure for proper inflation.
Too low of pressure will cause the Air Springs to rub
internally and lead to failure.
WARNING
Relieve Air System Pressure before attempting to
adjust or service Air Springs and Air Lines. Wear
protective gloves and safety glasses or goggles
when working with Air System. High pressure air
can propel debris at high speed, causing eye
injury or blindness. If you are injured, obtain
medical aid immediately.
Air System should remain pressurized at 90psi.
•
If Air System loses air pressure, pressurize Air
System to 90psi and check for leaks by spraying
soapy water on Push-to-Connect Fitting connections
and Air Springs. Repair as required.
•
Check Nylon Tubing for rubbing and kinks. Repair as
required. Nylon Tubing ends should be smooth, burr
free. Burrs can cause slow leaks.
•
Check Air Spring Guide Rod and Guide Rod Bushing
for excess wear. Relieve all System Air Pressure by
pulling Relief Valve Pull-Ring before attempting to
adjust or service Air Springs and Air Line Nylon
Tubing.
Front and Rear Roller
Adjustment
IMPORTANT
To maximize seed germination, peaks on Rear Roller
Wheels should line up with valleys on the Front Roller
Wheels. This will require adjusting the Clamp Bands
on each end of the Rear Roller Drum and moving the
Wheels until valleys and peaks line up.
NOTE
Failure to position the Clamp Band Socket Head Bolt
(Clamp Band open section) over the Roller Drum weld
seam will cause Clamp Band to loosen and slide.
After an initial run of 5-10 hours, check the Front and
Rear Roller Assemblies to ensure that the Wheels are
tight to one another and that the Clamp Bands are tight. If

not slide the Roller Wheels tight together per Roller
Adjustment Procedure below and adjust the Roller
Clamp Bands. Tighten the Clamp Band Socket Head Bolt
(Clamp Band open section) over Roller Drum weld seam
to 75 Ft-Lbs. Thereafter check Front and Rear Roller
Assemblies every 50-100 hours
Roller Adjustment Procedure
1. Adjust the Front Roller Wheels first. Loosen Clamp
Band and slide the Roller Wheels snug against
welded Roller End Plate. See Figure 5-5.
2. Position the Clamp Band Socket Head Bolt (Clamp
Band open section) over the weld seam on the Roller
Drum. See Figure 5-6. Change figure name to Roller
Adjustment
3. Slide the Clamp Band against the End Wheel of the
Roller and tighten the Clamp Band Bolt to 75 Ft-Lbs.
4. Adjust the Rear Roller Wheels by loosening the
Clamp Bands. Start at the center of the Rear Roller
and align the peaks of the Rear Roller Wheels with
the valleys of the Front Roller Wheels. This will
provide the best alignment of worn Roller Wheels and
maximize seed germination.
5. Position the Clamp Band Socket Head Bolt (Clamp
Band open section) over the weld seam on the Roller
Drum.
6. Slide the Clamp Band against the End Wheel on each
side of the Rear Roller and tighten the Clamp Band
Bolt to 75 Ft-Lbs
