DESCRIPTION
The Cherry G83 pneumatic-hydraulic lockbolt installation tool is a heavy duty production tool designed for high speed, reliable
installation of the most popular sizes of aircraft lockbolts.
This extremely powerful tool has been designed with many
ergonomic features: light weight (4.95 pounds) (2.25 kg.), less
recoil, low noise, and a comfortable fit in the operator’s hand. It can
be operated in any position with one hand.
By bending the rubber pin deflector (63) sideways, 1-1/2" additional
clearance can be obtained.
This tool can also be used to install blind bolts and blind rivets. See
the section on “Pulling Heads” for correct pulling head part number.
