Calibrating Torque Screwdrivers
To calibrate torque screwdrivers either use a torque tester or torque sensor within the range of
the torque screwdriver. For torque screwdrivers calibrate torque in "Peak" mode with a torque
tester or torque sensor. Make sure to apply the torque slowly and smoothly.
1. Select a torque tester or torque sensor that covers the torque range of the EMT screwdriver.
Connect screwdriver to the torque tester or torque sensor using the appropriate adapters as
needed.
2. Apply torque clockwise slowly until screwdriver 'slips' and note reading.
3. Adjust screwdriver to required torque setting as described below.
4. Test and repeat adjustment as necessary to obtain desired value.
5. Recalibrate torque screwdriver at prescribed intervals.
Adjusting Torque Setting (During Calibration)
1. Insert hex key into hole located at end of rubber grip.
(Note do-not attempt to remove rubber grip from the tool).
2. Turn hex key clockwise to increase torque and counter
clockwise to decrease torque. Do not adjust torque above or
below the recommended torque ranges.
3. Seal End Hole with Black RTV Sealant.
EMT 6, 9, 50 & 80 models are supplied with a T-Bar
1. Snap T-Bar into the slot located in the grip.
Setting and Applying Torque
1. Set desired torque on the scale. Pull down on the "Adjustment Ring"
and turn handle clockwise to increase torque and counter clockwise to decrease torque on the scale. Align the desired
torque value on the micrometer scale. Release "Adjustment Ring."
2. Tighten nut or bolt by applying steady twists. Screwdriver should be kept at 90 degrees to axis of bolt during tightening.
When pre-set torque is reached, the screwdriver will 'slip.'
3. The screwdriver will automatically reset itself for the next application.
4. With its unique cam-over design, it's impossible to over tighten beyond the preset
load.

Maintenance Schedule
Like an automobile, torque screwdrivers contain moving parts that require periodic servicing and lubrication.
Expected Tool Life
With normal use – 100,000 operations
Period between Resetting of Torque
5000 operations (as recommended in BS EN 26789:1994). It is acknowledged that some tools achieve 5000 operations in a
relatively short period of time. Under these circumstances the user may decide, with the benefit of their experience, to
increase the period between calibration checks.
Routine Maintenance
After 100,000 operations, strip, clean & re-grease the Spindle, Cam & Roller. Any worn components should be replaced.
Note: Any tool that is dismantled during its life must be re-lubricated in accordance with the Mountz recommendations. Do
not clean tools by immersing them in solvent, as this will destroy the internal lubrication and cause failure of the tool.

Testing & Servicing
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. Regular torque
calibration of a hand screwdriver ensures accuracy, repeatable tool perfor-
mance, and adherence to international standards.
We recommend a general once a year calibration interval. However, it is the
user’s organization that must determine suitable intervals based upon equip-
ment performance, application, degree of usage and management objec-
tives.
