BOLT TORQUE
Mounting bolts and hardware
Before operating the Disc Sealer 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 season.
All hardware used on the Disc Sealer 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 Disc Sealer 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.
