Additional safety instructions for electric staple guns

This electric staple gun is used for stapling or nailing wooden strips, films, sheets of material, paper, cardboard,
wire mesh and so onto wood or other suitable base materials.

 Unplug the tool from the mains before carrying out any work on it, especially filing the magazine with staples

or nails.

 Never point the tool at animals or people.
 Always check the plug and cable before use, and have any damaged parts replaced by a qualified speciali st.
 Always makes sure that the mains cable(2) is trailing away from the back of the tool.
 Never use different types of fastening material at the same time. Always make sure that fastening materials in

the magazine are of the same type.

 Never push the trigger lever down on an empty magazine.
 Leave the main switch (4) in the "Off" position ( 0 ) during work breaks.
 Wear eye protection when working with the electric staple gun.
 Remove all nails or staples from the magazine during longer work breaks or after finishin g work.
 Do not use this staple gun for fastening electrical cables. It is not designed for electric cable installation and

may damage the insulation of electric cables thereby causing electric shock or fire hazards.

 Immediately stop using the staple gun if it is either faulty or not working properly, and bring it to an expert to

be checked over.

 Use the staple gun away from children, and keep it out of children’s reach.

Always wear eye protection during use!

• The vibration emission level given in this information sheet has been measured in accordance with a

standardized test given in EN 60745 and may be used to compare one tool with another.

• The vibration emission level will vary because of the ways in which a power tool can be used and may
increase above the level given in this information sheet. This could lead to a significant underestimate of
exposure when the tool is used regularly in such a way.

• Note: To be accurate, an estimation of the level of exposure to vibration experienced during a given period of
work should also take into account the times when the tool is switched off and when it is running but not
actually doing the job. This may significantly reduce the exposure level over the total working period.

Suitable nails and staples:

You can use staples with a length up to 25 mm or nails with a length up to 32 mm with this electric staple gun.

Loading of staples (Fig. 3) or nails (Fig. 4)

 Unplug the tool from the mains.
 Push the staple feeder catch (7) at the back of the tool towards the magazine, and pull out the staple feeder

(5).

 Warning: Once the staple or nail strip has been placed in the feeder, it will be spring-loaded. Hold the catch

firmly to prevent the feeder from suddenly being ejecting from the tool.

 Place the staple strip (Fig. 3) or nail strip (Fig. 4) into the magazine.
 Push the staple feeder (5) back to the front and secure by hitching the catch (7) behind the opening in the

housing.

Usage

The tool has double protection against inadvertent operation:

1. Switch the main switch (4) to the "Off" position (0) to lock the trigger (1).

2. The contact switch (6) ensures that the staple gun is only triggered on contact with a material surface.

 Place the opening of the electric staple gun firmly onto the material and squeeze the trigger (1).
 Additional pressure applied to the front of the tool will prevent recoil and increase the force applied to the

nails or staples. This is especially important for ensuring that the nail or staple is driven the whole way into a
hard surface.

Hammer-force Preselection

With the thumbwheel for hammer-force preselection (3), it is possible to preselect the required hammer force.
The required hammer force depends on the length of the staples or nails, and on the strength of the material.
Always test the selected hammer force on scrap material first.
The optimum hammer-force setting can be determined only by trial and error.
