BOLT TORQUE
Regularly inspect each residue manager for loose or worn bolts & hardware. Repair or replace as needed.
All hardware used on the 2940 Air Adjust 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.

DANGER: Denotes the most serious specific potential hazard.
SAFETY PRECAUTIONS
You can make your farm a safer place to live and work if you observe the safety precautions given. Study these

performing service.
If the machine must be serviced in the raised position, jack or block it up to prevent it from accidentally falling
and injuring someone.
Do not allow riders on the tractor or implement.
Use speeds and caution dictated by the terrain being traversed. Do not operate on any slope steep enough to
cause tipping or loss of control.
Be sure all personnel are clear of the immediate area before operating.
Read and understand the operator’s manual and require all other persons who will operate the equipment to do
the same.
Be familiar with all tractor and implement controls and be prepared to stop engine and implements quickly in an
emergency.
CAUTION
Consult your implement and tractor operator’s manual for correct and safe operating practices.
Beware of towed implement width and allow safe clearance.
FAILURE TO HEED MAY RESULT IN PERSONAL INJURY OR DEATH.
