GENERAL INFORMATION

Date of first use: The date the unit is removed from the packaging.

Date of first use*                 dd / mm / yy

Instructions shall be retained and provided to all Users of the Latchways GTFAs and Latchways VLLs in the language of the destination country, even when resold.
All Users of Latchways GTFA and Latchways VLL shall read and follow these instructions. Retain these instructions for future reference. Failure to follow these instructions may seriously compromise the safety of the User.

INTENDED USE AND PRODUCT LIMITATION

The Latchways GTFA is designed to arrest the fall of a User in conjunction with a Latchways VLL. The system or device energy absorber reduces the load applied to the body to 6 kN (1,350 lbf) or less in the event of a fall. Lifeline systems may be designed
either with or without integral energy absorption. It is therefore essential that the User ensures that the individual device is compatible with the system (Table 1). If there is no system energy absorption then only devices that include an energy absorber
shall be used.

The device has an anti-inversion mechanism which prevents it being used on the Latchways VLL if there is an attempt to use it upside down.

The required minimum distance below the User’s feet and the working platform is 2 m (6’6”). Below 2 m (6’6”) the User may not be protected against hitting the working platform or obstacles below. Therefore, extra care must be taken when ascending /
descending the first 2 m (6’6”).

Temporarily disabling or manually handling the lock/release mechanism of the device during ascent or descent may hinder the safe operation and diminish the effect of the braking mechanism.

The Latchways devices have been subjected to an additional series of tests devised by TUV/NEL. These tests were conducted using 71 kg (156 lbs) and 100 kg (220 lbs) anthropomorphic test dummies with different body postures (reference NEL certificate no. MTHH).

Maximum Rated Load: Maximum single User mass is 150 kg (including tools and equipment carried). Total system User mass is determined by the device type and system configuration as illustrated in Table 1.

REQUIRED EQUIPMENT

Always use a correctly adjusted Full body harness complying with national standards. (For countries conforming to EN standards a Full body harness conforming to EN 361 and equipped with a front fall arrest attachment point (A), including a clear statement on the required position of the harness attachment point is required).
Waist belts are not suitable for use with this device. If the Full body harness becomes loose a safe location shall be found before it is correctly adjusted. Harnesses that include elastic webbing at the front connection point are not suitable for use with this device.

Attach the Latchways GTFA to the Full body harness front attachment point using the karabiner. Before use ensure the karabiner is in the closed and locked position.

REQUIREMENTS FOR  USE

The Latchways GTFA shall be directly attached to the front chest position of a Full body harness when used on a Latchways VLL. When the device is attached to the cable the horizontal distance from the cable to the harness front attachment point is 0.3 m, (12”) which allows the User to ascend / descend unhindered, this must not
be extended, shortened or have any components added or removed

All Users shall ensure that a minimum distance of 3 m (10 ft) is maintained between the head of each User and the feet of each system User.

          WARNING

• The Latchways GTFA shall only be engaged or disengaged from the Latchways VLL system when the User is in a position where there is no risk of a fall occurring.

Failure to follow this warning can result in serious personal injury or death.

LATCHWAYS VLL TYPES

Latchways VLLs may be designed either with or without integral energy absorption. It is therefore essential that the User ensures that the individual device is compatible with the system ( Table 1 ). If there is no system energy absorption then only devices that
include an energy absorber shall be used.

PRE-USE CHECKS

Always fully inspect the following before each use:

System tension Ensure the system indicator provided is correct:

Tenser disk (Figure 2) – Only use the system if the Tenser disk freely rotates.

Visual tension indicator (Figure 3) – This component allows the User to check the system tension in situations where it is impractical to reach a tension indicator disc from a position of safety.

VLL system label – Check the product label, all regulatory information (installation date, ID, max. users, system type and inspection date) shall be clearly legible.

Complete the Latch ways GTFA Pre use checks in accordance with Table 2. Inspect the system for any excessive wear, damage or corrosion and evidence that it is within its service life. Ensure that the device is compatible with the system and sufficient energy absorption is provided ( p104 – Latch ways VLL system label).

If the Latchways GTFA does not pass any of the pre-use checks, it shall be immediately withdrawn from service. This shall be recorded on the record card and the device passed to a Technician1 for disposal or repair.

USER INSTRUCTIONS

1. Hold the Latch ways GTFA in the right hand by the release catch cover below the level of the attachment point so that the linkage is in the vertical plane. This will force the cam into the unlocked position. Figure 4.
2. Press the release catch with your right thumb. The release catch will not operate if the device is incorrectly oriented. Using your left hand pull the Star wheel away from the body of the device and offer the device up to the cable. Figure 5.
3. Move the device around the cable until the cable is held within the cavity in the body of the device. Remove your thumb and allow the release catch to return. Finally allow the star wheel to move back into its original position, check that the release
catch has disengaged and the star wheel cannot be pulled out. Figure 6.

4. To check the device is fully engaged move the device up the cable then quickly pull down on the karabiner the device should lock onto the cable. If this does not happen, remove the device from service and do not use until the device has been
recertified by a Technician1
