REMOVING THE CHUCK SCREW: Set the Speed Selector Slide to the #1 setting.

With the aid of a small pencil tip torch (or use an air reduction nozzle on a heat gun) apply heat
into the chuck opening, directly to the head of reversing screw just prior to removing the screw.
Place a T40 1/4” torx bit into the head of the reversing screw and place a 1/4” boxed end wrench
over the hex on the T40 bit. It is recommended to use a 12”-18” metal tube or pipe as leverage
over the boxed wrench. In a clockwise direction apply a slow, steady force on the ‘cheater bar’
to break the screw loose.

REMOVING THE KEYLESS CHUCK:

Tighten a 3/8” or 10mm Allen Key into the jaws of the chuck. Place
the tool into a vise with soft jaws (this will require that you remove
the belt clip from the tool). It is recommended to use a 12”-18” metal
tube or pipe as leverage over the allen key. In a counter-clockwise
direction apply a slow, steady force on the ‘cheater bar’ to break the
chuck loose.

INSTALLING NEW CHUCK AND SCREW:

Torque Chuck to 1095 kg/cm (950.418 in/lbs or 79.20 ft/lbs)
Torque Screw to 400 kg/cm (347 in/lbs or 28.93 ft/lbs)

62 A clean, dry surface is essential for proper performance
for any adhesive system. The area intended for
application of any adhesive label or nameplate must be
prepared by cleaning with isopropyl alcohol. The
solvent is to be applied with a clean, lint free applicator
and the surface allowed to dry before applying the
label or nameplate.
