Technical Specifications
WARNING Avoid the risk of electric shock or severe injury. When the power cable gets damaged it should only be replaced by the manufacturer or at a Authorized Service Center. The build quality of the electric insulation is altered if spills or liquid gets into the tool while in use. Do not expose to rain, liquids and/or dampness. Before gaining access to the terminals all power sources should be disconnected.
Power Requirements
WARNING
Tools with double insulation and reinforced insulation are equipped with a
polarized plug (one prong is wider than the other). This plug will only fit in
the right way into a polarized outlet. If the plug cannot be introduced into
the outlet, reverse the plug. If it still doesn’t fit, call a qualified
electrician to install for you a polarized outlet. Do not alter the plug in
any way. Both insulation types eliminates the need of both a grounded third
power cord with three prongs or a grounded power connection.
WARNING
When using an extension cable, verify the gauge is enough for the power that
your product needs. A lower gauge cable will cause voltage drop in the line,
resulting in power loss and overheating. The following table shows the right
size to use depending on cable’s length and the ampere capability shown in the
tool’s nameplate. When in doubt use the next higher gauge
WARNING When operating power tools outdoors, use a grounded extension cable labeled “For Outdoors Use”. These extensions are specially designed for operating outdoors and reduce the risk of electric shock

Operation
-
ecurely hold the tool and place the nut onto the screw or bolt. Start the tool and tighten for the appropriate amount of time.
NOTE: -
When attaching an M10 (3/8”) or smaller screw, carefully adjust the pressure on the switch so that the screw is not damaged.
-
Hold the tool pointed directly at the bolt or nut without applying excessive pressure to the tool.
-
If a screw is tightened for a very long period of time, the screw or nut can become fatigued, damaged, etc.
-
Before beginning your work, always run a test operation to determine the appropriate time for your screw. Especially for screws larger than M10 (3/8”), the above test operation should be done to prevent problems in the nut or screw, etc.
-
The tightening torque is affected by a wide variety of factors including the following. After tightening, always check the tightening torque with a torque wrench
-
Voltage.
Voltage drop will cause a decrease in the clamping force. -
Nut.
-
If the correct size nut is not used, the tightening torque will be reduced.
-
If a worn nut is used (wear on the hex end or on the square end), the tightening torque will be reduced.
-
Screw
Even if the torsion coefficient and screw class are the same, the appropriate tightening torque will vary depending on the diameter of the screw. Even if the diameter of the screw or bolt is the same, the correct tightening torque will vary according to the torsion coefficient, class and length of the bolt or screw. -
Material.
The type of material and the surface finish of the material will affect the tightening torque. -
Tightening Time.
Longer tightening periods will result in a higher tightening torque. Using a longer tightening period than recommended could cause the fastener parts to roll or damage the threads or screw parts. -
The way you hold the tool or material in the tightening position will affect the torque.
Maintenance
Cleaning and Care
- To guarantee the proper cooling of the motor, always keep the air vents clean and free of obstructions.
- Regularly inspect all the mounting nuts and double check the screws are tight. If a screw is loose, tighten immediately.
