How to Indentify a FGA v2 model
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.

Note: Do not adjust torque above or below the designated torque ranges for the torque screwdriver. If you exceed the upper
torque range capacity of the screwdriver, the tool's screen will display the letter "H." If you exceed the lower torque range
capacity of the screwdriver, the tool's screen will display the letter "L."
Torque Setting Increments
The screwdriver's torque settings are selectable in increments.

Applying Torque
1. Tighten the fastener or bolt by applying a steady twist. 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 over-tighten beyond the pre-set load.

Battery
When a low battery status is detected, the FGA will indicate it by displaying "bAt" on the
screen. The battery needs to be replaced.
Note: The FGA doesn't have a battery status icon that displays the battery level status
permanently. The low battery indicator will only display once the estimated battery life is <10%
Battery Replacement
1. Use a 1.5mm hexagonal key to loosen the two screws and remove
the battery cover.
2. Remove the battery from the battery holder.
3. Insert a new battery.

4. Install a battery cover.
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
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.
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.

Calibrating Torque Screwdrivers
Please view the FGA calibration instructions document.
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.
