BOLT TORQUE
Mounting bolts and hardware
Before operating the Residue Manager for the first time, check to be sure that all hardware is
tight. Check all hardware again after approximately 50 hours of operation and at the beginning
of each planting season.
All hardware used on the Residue Manager 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.
Lubricate all bearings and moving parts as assembled and make certain that they work freely.
WARNING: Never work around the toolbar/implement while in a raised position without using safety
lockups.
CAUTION: The Residue Manager attachments are very heavy. Pay extra attention to lifting techniques
while handling and or maneuvering the opener during assembly. Failure to do so may lead to personal
injury.
