How to Indentify a FGA v1 model fr
o
There are two ways to identify whether you have a v2 or a v1 model.
1.
The v2 models has separate battery access cover (see page 2) on the lower side of the
handle. The v1 models does not.
2.
Second option is to move the locking bar
knob (CCW direction) below the torque range capacity. Once you pass the letter "L," if it
displays a firmware version, the model is a v2 model.

Torque Setting
Slide the locking bar slide mechanism to the unlock position. Use the black adjustment knob to change torque settings. Turn
knob clockwise to increase torque and counterclockwise to decrease torque. After selecting your toque value, slide the locking
bar slide mechanism to the lock position. The display stays on for 20 seconds then goes into Sleep mode. Per ISO:6789-1,
the torque setting is only certified when adjusted from the bottom-up. Top-down adjustment is not certified by
Mountz.
Applying Torque
1. Tighten fastener or bolt by applying steady twists. Keep the screwdriver in line with the axis of the bolt during tightening.
The screwdriver will ‘slip’, after achieving the pre-set torque setting.
2. The screwdriver will automatically reset itself for the next application.
3. With its unique cam-over design, it’s impossible to overtighten beyond the pre-set load.
Calibrating Torque Screwdrivers
FGA calibration instructions are available upon request.
Maintenance Schedule
Like an automobile, torque screwdrivers contain moving parts that require periodic servicing and lubrication.
Expected Tool Life
With normal use – 1,000,000 operations
Period Between Recalibration
20,000 fastening operations. It is acknowledged that some tools may achieve 20,000 operations in a relatively short period of
time. Under these circumstances, the user may decide to increase the period between calibration intervals with the benefit of
their experience.
Battery
The battery is recommended to be replaced when the screwdriver is sent in for recalibration.
Routine Maintenance
After 100,000 operations, strip, clean and re-grease the spring, bearings and internal components. 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 a solvent, as this will destroy the internal lubrication and cause the failure of the tool.
Warranty
Mountz FGA tools are the only cam-over drivers on the market to offer a two-year unlimited warranty. If it breaks in any way,
we’ll fix it or replace it for free.
Lifetime guarantee against manufacturing defects. We only make the highest quality products. This driver will not have a
defect, we stake our quality reputation on it.
Warranty does not include battery replacement.
Testing and 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 performance, 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 equipment performance, application, degree of usage and management objectives.
