ASSEMBLY
BOLT TORQUE
Mounting bolts and hardware
Before operating the FERTILIZER TOOLBAR 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 FERTILIZER TOOLBAR 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 FERTILIZER TOOLBAR and its 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.
