The mini power supply is designed for operating only the Mini EF-Series
brushless electric screwdrivers (EF030, EF040 & EF055 models).
Power
Securely place the power cord into the back of the ET-30D. The LED
light on top of the unit will display “Red” indicating the unit is receiving
power.
Connecting Electric Screwdriver
1. Attach power tool cable to the electric torque screwdriver and
ET-30D Controller. Make sure the notch in the plug lines up with the
notch on the socket. Tighten knurled ground ring.
2. Turn driver on and check for proper rotation. FOR-clockwise,
REV-counterclockwise.
3. To apply torque with the electric torque screwdriver, squeeze the
lever. The electric torque screwdriver will automatically stop when the
preset torque has been reached.

Mountz Torque Testers and Calibration Equipment
Torque tools go out of calibration with use. Calibrating a torque tool is
a fine-tuning process of bringing the tool back within its tolerance.
Torque testers can also be used for quick tools tests on the line or in
the lab to determine whether torque tools are holding a given setting.
A regular torque tool calibration and re-calibration guarantees the
operator repeatable accuracy and adherence to international stan-
dards. Torque testing also ensures torque equipment is operating to
peak performance and can highlight potential tooling problems before
they arise perhaps due to tool wear or broken components.
Controlling torque is essential for companies to ensure their product's
quality, safety and reliability isn't compromised. The failure of a three-
cent fastener that isn’t properly tightened can lead to catastrophic or
latent failures. Fasteners that are insufficiently torqued can vibrate
loose and excessive torque can strip threaded fasteners. Using a qual-
ity torque tool has become increasingly important for many companies
to ensure that proper torque is being applied and maintains gauge
requirements associated with the ISO 9001 Quality Standard. Look for
the Mountz hexagon logo - it's a stamp for quality tools, service and
knowledge in the field of torque control.
