BOLT TORQUE
Before operating the 10000 Series Magnum
™
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 10000 Series Magnum
™
is Grade 5 unless otherwise
specified. 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 table below 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.
