11. Inspection and maintenance
11.1. Daily inspection
Careful inspection is paramount to maintaining device safety; perform the inspection
procedures outlined in this section diligently and in a timely manner. Failure to follow
these procedures may lead to severe personal injury or even death!
You as an end user or operator assume complete responsibility for incidents arising
from lack of timely inspection and/or maintenance.
Self Belay device and its components shall be inspected daily before the start of each work
day in order to ensure their safety and smooth operation. The following procedures shall be
followed in order to ensure optimal safety and eciency.
1.Overall device check
Inspect visually the Self Belay device; note any missing, deformed or broken components.
Note: during use, it is normal for the device to receive occasional scratches and accumulate
surface damage from contact with rough surfaces. Coating will also start wearing out,
particularly in areas where the device is being held while opening or closing, as well as areas
around the key and quicklink opening This is normal and to be expected.
2. Self Belay key check
Inspect closely the Self Belay key; pay particular attention to the condition of the middle pin.
If it is bent, partly or completely broken, stop using the key and replace it immediately.

page 15
111v Tsarigradsko Shose blvd, 1784 Soa, Bulgaria | [e-mail] | www.safetyeng.eu
3.Self Belay key measurement
Measure the width of the middle pin of the Self Belay key as shown; measured value should be
above 2.8 mm. This dimension is between 3.6 and 3.8 mm as manufactured; if the measured
value is close (but still above) 2.8 mm, consider ordering replacement keys.
If the key fails the measurement check, replace it immediately before using the device again.
4.Self Belay covers check
The plastic covers on both sides should be inspected for cracks and damage; missing or
damaged covers should be replaced in a timely manner. Note that the covers are not part of
the warranty for the device as they are considered consumable.

page 16
111v Tsarigradsko Shose blvd, 1784 Soa, Bulgaria | [e-mail] | www.safetyeng.eu
5.Swivel check
The condition of the swivel must be checked by twisting the upper part as shown in Photo 1
below. It should rotate freely in both directions.
5. Swivel pin check
Inspect the swivel pin for damage or deformation; stop using the device immediately if the
pin is broken or deformed!
If the swivel is deformed, damaged or shows signs of cracking, stop using the device
immediately. Contact Safety Engineering for a replacement.
Make sure that the lock washer in the end of the swivel pin is present and cannot be removed
by hand. If the washer has fallen out, stop using the device until the washer is replaced.

111v Tsarigradsko Shose blvd, 1784 Soa, Bulgaria | [e-mail] | www.safetyeng.eu
7. Quicklink check
Inspect the quicklinks that are currently in use on participant harnesses; note any damage,
cracks or permanent deformation of the quicklink. Make sure the attachment rotates freely.
Check for wear the place where the quicklink is in contact with the harness; if there is visible
wear, measure the smallest thickness in the worn out place; minimum thickness should be at
least 6.5 mm.
Make sure the nut of the quicklink is tightened well when installed on the harness. If loose,
tighten carefully (maximum torque: 3 N.m)
If the quicklink is deformed, damaged or worn out beyond threshold value given above, stop
using the quicklink and replace it immediately.
8.Functional check
When all previous checks are completed, proceed to check the functionality of the device.
Insert quicklink in the device as normal; the quicklink should slide in easily and without eort.
Rotation of the discs should be smooth and without friction.
If the discs rotate with diculty, apply dry lubricant in spray form (e.g. graphite or silicone-
based) and insert the quicklink several times to spread out the lubricant.
With the quicklink inserted all the way, remove the key from the device; key should slide out
easily without excessive eort.
When the key is out of the device, verify that the Self Belay is rmly locked and the quicklink
cannot be taken out.
Replace the key in the device and remove the quicklink from the Self Belay; quicklink removal
should be easy and not require excessive eort.
Verify that the key cannot be removed from the device when the quicklink is not inserted.
Repeat the steps above at least 3 times.
