GENERAL SAFETY RULES
WARNING! Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or
serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create
sparks which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Grounded tools must be plugged into an outlet properly installed and grounded by all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use ungrounded plugs? . Check with a qualified electrician if you are in doubt
as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user.
Avoid body contact with grounded surface and pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock
if your body is grounded.
Don't expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock
Take care when using and handling the power/data cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep
the cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
When operating a power tool outside, use an outdoor extension cord marked W-A or W. These cords are rated for outdoor use and
reduce the risk of electric shock.
Personal Safety
Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tool while tired or under the
influence of drugs, alcohol, or medication. A moment of inflation while operating power tools may result in serious personal injury.
Dress according to local safety guidelines . Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
Avoid accidental starting of tool(s). Be sure the switch is off before plugging in. Carrying tools with your finger on the switch or plugging
in tools may result in personal injury.
Remove adjusting keys or switches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may
result in personal injury.
. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used
for appropriate conditions.
Tool use and Care
Use clamps or another practical way to secure and support the workplace to a stable platform. Holding the work by hand or against
your body is unstable and may lead to loss of control.
Do notoperate a tool beyond its defined limits. Use the correct tool for your application. The correct tool will do the job better and
safer at the rate for which it is designed.
Do not use the tool if the switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool.
Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges, are less likely to
bind and are easier to control.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the operation of the

3
tool. If damaged, have the tool serviced before using it. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool, may become hazardous when used on another tool.
SERVICE
Tool service must be performed only by qualified personnel. Service or maintenance performed by unqualified personnel could result
in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of
unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its cord.
Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.
Never lubricate aerosol oil on to the electrical part.

There are four scenarios needed to be taken into consideration to adjust torque Output on
EC-Series DC Controllers:
1. Tool Calibration from Factory
Tools gearbox and servo motor are tuned to reach maximum efficiency during the manufacturing process. DC
Controller is calibrated using ISO17025 certified torque tester. Results are saved to both driver and control unit
memory. Customers will notice under “torque calibration %” that brand new units will show 100%.
NOTE: ANY OTHER MODEL OR BRAND OF TORQUE TESTING EQUIPMENT USED TO VERIFY CONTROLLER
READINGS FROM FACTORY MIGHT SHOW DIFFERENT RESULTS
2. Tool Preset @ Specific Torque Setting @ the time of purchase
This option can be selected by the customer when acquiring a new system. Mountz Service Department would
generate an ISO17025 traceable calibration certificate
The customer would have to indicate the torque setting needed to be certified
NOTE: THIS CERTIFICATE loses VALUE AS SOON AS CUSTOMER CHANGES TORQUE CALIBRATION % VALUES ON
CONTROLLER SETTINGS
3. DC Controller torque verification @ customer’s site
Customers can choose to use their existent torque testing equipment to validate and calibrate DC Controller at any
time.
Under this scenario, the customer takes readings from the controller and if these do not match to their torque testing
device, simply adjust Torque Calibration % up and down until matching reading with torque tester device.
Customer can perform this verification using two ways:
a) Statically, using a torque testing device
b) Dynamically, using a Rotary Sensor and taking readings directly at the application
NOTE: MAKE SURE DURING THIS PROCESS, TO DOCUMENT TYPE OF JOINT, SPEED, TOLERANCE, AND TESTER
FEATURES TO ASSURE SAME RESULTS NEXT TIME THIS PROCESS IS REPEATED
Note: Tool Calibration affects all programs (presets). Tool Calibration is stored on the Driver Memory
4. Torque Transference to joint or customer’s application.
DC Controller is either calibrated and verified torque from the factory, or customer's location using their torque
testing equipment. Assuming that torque will be 100% transferred to joint or application would be inaccurate.
Depending on the application or joint conditions; installed torque on the product could be minimum, or it also could
be a big difference. Joint characteristics are completely different from one application to another. Users must make
sure they understand these differences and act accordingly.
Best way to acknowledge this will be with the use of a Rotary Sensor connected to a torque tester device and attached
to the DC Controller Driver. Take some readings on the product been assembled, compare them to Controller
readings on display. These readings must be very close to the same. If not, adjustments to the controller must be
made.
a) The best-recommended scenario would be torque compensation @ controller PRESET level. This adjustment
affects the specific PRESET settings been used on that application.
b) If the tool is been used permanently on the same application, it would be recommended to simply adjust
Torque Calibration % that would store value to the entire system. All default presets.

How to:
Tool Compensation (PRESET LEVEL)
This option is done at the preset
(program) level. On a specific preset, a
customer might need to lower or exceed
the minimum or maximum torque
capacity of the tool been used on the
preset.
MD-Series offers the possibility of
lowering or increasing motor power to
achieve this unique feature. Setting A015
offers this possibility and customers can
be adjusted up to +/-20%. This is adjusted
when an application target torque slightly
exceeds max or min torque capacity.
Mountz strongly recommends selecting a
higher or lower torque capacity tool if this
feature will be adjusted permanently.
NOTE: Tool Compensation adjustment affects only the selected preset (program), this means that all other presets will
remain as normal. Tool Compensation is stored on the Controller Memory
NOTE: It is Mountz's recommendation to a customer to periodically verify torque accuracy of EC-Series DC
Control System with an ISO17025 Certified torque verification meter and ensure the quality of their process.
It is up to the customer's standards to determine how often the tools need to be validated or verified.

Torque calibration using Controller’s Software
When the reading on the torque meter master is lower than the setting on the tool, increase the calibration value more
than 100(%) which is basic on production. To increase the output torque 5% more, key in 105(%). The calibration value
works through a whole range of torque. It will be refreshed and stored in the memory of the tool so it can be still effective
when using the tool on another controller.
NOTE: Different Torque Analyzer Master will provide different results. Make sure you always use the same ISO17025
Torque Analyzer Master with the same accessories and testing conditions: RDA, Tool Speed, Tester Filter Setting, Torque
Arm to obtain valid results.
