7 METHOD OF EXECUTION

7.1 General

o This chapter explains the importance of knowing pertinent data of the tool to be used for the installation of floorings, walkways and other related safety amenities at C2 FD.

o The application will also covers the other sites i.e. FC, FB, FA, etc. of the ACC o Refer to document T-4.121.350 for related description of works to be undertaken. o The tool refers to Hilti DX 76 o It is essential that operating instructions are read and comprehended before the tool is

operated for the first time and during the duration of installation period.

o It is also essential to know where the fasteners and its combination will be applied in the ACC. o Emphasis will be given on the safety features of the tool. o Procedures on the installation of plates using the special tool are also described herein. o This is also established in order to assure that all works are carried out without flaws before

execution of works and start up.

7.2 Description and Safety Features

7.2.1 Piston Principle

o Piston principle: the energy from the propellant is transferred to the piston, accelerated mass of which drives the fastener into the base material. Due to use of this principle, the tool is classified as "low velocity tool". Approximately 95% of kinetic energy is taken up by the piston when the tool is fired. As the piston is always stopped as it reaches the end of its travel, excess energy is absorbed by the tool. Accordingly, when the tool is used correctly, dangerous through-shots with a fasteners exit velocity in excess of 100 m/sec therefore become virtually impossible.

o Drop-firing safety device: the drop-firing safety device is the result of coupling the firing mechanism with the cocking movement. This prevents the tool from firing when dropped onto a hard surface, no matter at which angle the impact occurs.

o Trigger safety device: the trigger safety device ensures that the fastener cannot be driven simply by pulling the trigger only. The tool must be pressed against a firm surface before a fastener can be released.

o Contact pressure safety device: the tool can be fired when pressed fully against a firm surface with a force of 50 N

o Unintentional firing safety device: the tool is equipped with an unintentional firing safety device. This prevents the tool from firing if the trigger is first pulled and the tool is pressed against the work surface. The tool can be fired only when it is pressed correctly against the work surface and the trigger subsequently pulled.

7.2.2 Operation and safety precautions

o The tool is powder actuated fastening with magazine and for hand held only o It is completely independent from external power sources o It is a "low velocity tool" due to Hilti proven piston principle as explained in 7.2.1



T-4.250.954 Rev. A Page 11 of 48

QQQ AAA TTT AAA RRR

o The tool is intended for the use in the construction industry and associated trades for driving fasteners of various types (nail, threaded studs and composite fasteners) mainly into steel. In our case; flooring sheets and checkered plates will be fastened to the steel structures to form walkways and safe access for people to work at the ACC.

o The tool and its ancillary equipment may present hazards when incorrectly used by untrained personnel or not as directed; hence the consequences will be analyzed thoroughly.

o To operate: press the tool against the work surface at right angle and squeeze the trigger. Driving the next fastener, push the cycling grip back toward the rear of the tool and then forward position, and so onTool is equipped with power regulation from 1 to 4 (minimum to maximum), adjustment control of the penetration will be done as required.

o Maintenance will be carried out only by people with sufficient knowledge of the tool or its manufacturer/vendor

o When not in use, store in a dry place and locked up

2. Description

2.1 Piston principleThe energy from the propellant charge is transferred toa piston, the accelerated mass of which drives the fas-tener into the base material. Due to use of this pistonprinciple, the tool is classified as a low velocity tool.Approximately 95 % of kinetic energy is taken up by thepiston when the tool is fired. As the piston is alwaysstopped as it reaches the end of its travel, excess energyis absorbed by the tool. Accordingly, when the tool isused correctly, dangerous through-shots with a fastenerexit velocity in excess of 100 m/sec therefore becomevirtually impossible.

2.2 Drop-firing safety deviceThe drop-firing safety device is the result of couplingthe firing mechanism with the cocking movement. Thisprevents the tool from firing when dropped onto a hardsurface, no matter at which angle the impact occurs.

2.3 Trigger safety deviceThe trigger safety device ensures that a fastener cannotbe driven simply by pulling the trigger only. The toolmust be pressed against a firm surface before a fastenercan be released.

2.3.1 Contact pressure safety deviceThe tool can be fired only when pressed fully against afirm surface with a force of at least 50 N.

2.3.2 Unintentional firing safety deviceThe tool is also equipped with an unintentional firingsafety device. This prevents the tool from firing if thetrigger is first pulled and the tool then pressed againstthe work surface. The tool can be fired only when it isfirst pressed correctly against the work surface and thetrigger subsequently pulled.

Location of identification data on the toolThe type designation and serial number are printed onthe type plate on the tool. Make a note of this informa-tion in your operating instructions and always refer toit when making an enquiry to your Hilti representativeor service department.
