8”Z1 CORE DRILL
7
MACHINE COMPONENTS
Ø The main components of the 8”Z1 are the spindle, gearbox, motor, carriage, drill
stand and base. The spindle is driven by the transfer case and the motor.
o These components must be not be removed except by a qualified technician.
Power must be disconnected prior to any service.
Ø This machine has one primary adjusting point for the travel between the drill carriage
and the drill stand. The main way to increase or decrease the users ability to move
the drill by hand is with this system. These are the black hex bolts on the side and
back of the machine that have a locking nut around them. These are generally used
to tighten up the travel as the slides wear over time. Be mindful to evenly adjust
these so that the travel is even and smooth. The ideal travel generally keeps the drill
in place when the user is not using the drill (this is usually on the tighter side)
although individual users needs may vary. The side black carriage bolt can also be
used for temporarily locking the carriage in place.
