4”Z1DRILLING RIG

MACHINE COMPONENTS

Ø The main components of the 4”Z1W/S are the spindle, gearbox, motor and drilling rig

(carriage, 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.
