1. About this document These instructions supplement the basic Quick-Lock user manual.
They specifically describe how to use the Quick-Lock liner end sleeve > 700.
Please observe the aforementioned user manual with its general instructions on using the Quick-Lock system.
1.1 Regulations
The basis and general specification for pipe repairs using the Quick-Lock system is
DWA data sheet M143 Part 3 “Repairing wastewater pipes and sewers with internal sleeves”
See the main user manual.

2. Description of the Quick Lock LEM >700
2.1 Intended use
Cross-section
The Quick-Lock liner end sleeve > 700 is a product for permanently and tightly sealing liner systems
to the host pipes or manhole pipe connections in the range of diameters from DN 700-DN 1200.
2.2 Suitability and materials used
The system is made from V4A stainless steel of grade 1.4404 (AISI 316L) a nd an EPDM compression
seal. The materials used are permanently resistant in municipal wastewater systems. The suitability of
the materials must be ascertained for use in industrial or polluted wastewater.
The Quick-Lock liner end sleeve may only be installed in cured, stress-free liner systems.
Hydrophilic waterstop tape does not need to be used around the liner.
The basis for selecting a suitable liner end sleeve is the technical data sheet (appendix 1).
Observe the instructions in section 1.6 of the main user manual.

3. How to use the system
3.1 Preparation
3.1.1 Inspecting the pipe
Before using the Quick-Lock liner end sleeve, check the area where the liner is connected to the host
pipe or the manhole pipe connection to see whether the liner end sleeve is suitable.
3.1.2 Preparing the pipe
Repairing the contact surfaces
A reliable compression seal is only possible if the quality of the surface is suitable for sealing.
Repair any irregularities or holes in the host pipe or the manhole pipe connection.
Only used mineral or epoxy-based materials.
Let the material cure.

10 Version:03/2015
3.3 Preparation: Trimming the liner
Fitting the depthstop
Measure the thickness of the liner.
Fit the appropriate depth stop onthe
pneumatic cutter.
Trimming the liner
Using the pneumatic cutter, make a radial cut around the entire sleeve circumference.
Liner trimlength:
DN 700 – DN 1200: 265 mm
Measure from the position where the front edge of
the sleeve will be.
Make a longitudinal cut with a pneumatic angle grinder. Do not damage the host pipe.
Remove the liner offcut.
Deburr the new end of the liner with the angle
grinder.
Clean the area where the liner will be connected with a high-pressure jet.
Longitudinal cut
Make a longitudinal cut with a pneumatic angle grinder. Do not damage the host pipe.
Remove the liner offcut.
Deburr the new end of the liner with the angle
grinder.
Clean the area where the liner will be connected
with a high-pressure jet

3.4 Installing the Quick-Lock LEM >700
Installation
Bringing in thesleeve
Do not assemble the sleeve.
Bring in the sleeve via the manhole entrance.
Remove the edge protection on the metal rim.
Putting the sleeve together
Join the sleeve sections together so that their
respective engraved tracks are on the outside.
Place the sliding blocks in the tracks.
Secure the sliding blocks with the locking screws.
Adjust the sleeve to the smallest diameter and
tighten the locking screws.
Applying talcum powder to the rubber jacket
Apply talcum powder to the inside of the rubber
jacket.
12 Version:03/2015
Fitting the rubberjacket
Pull the jacket over the sleeve and center it on the 300 mm wide (without rims) steel sleeve.
The preassembled sleeve is rolled so tightly that it can be taken into the pipe and turned around
there.
Fitting compensating rubbers (if necessary)
For greater liner thicknesses, one or two
compensating rubbers must be mounted (see data
sheet).
Peel back the rubber jacket.
Pull on one or two compensating rubbers over the sleeve (on the side with the larger border).
Fold the rubber jacket back over the
compensating rubbers.
Check for correct seating.
Aligning the rubber jacket
Check and correct the fit of the rubber jacket:
Position the compensating rubbers so thatthe
edges lie under each other (see figure).
13 Version:03/2015
Positioning the liner end sleeve in the host pipe
Depending on the type ofconnection:
Alternative A (standard method):
Connecting to liner in host pipe
Rubber jacket is seated in the center around the
steel sleeve.
Alternative B:
Connecting to liner in manhole pipe connection
Rubber jacket is seated in the center around the
steel sleeve.
This requires that the surface of the manhole pipe
connection be suitable for sealing and that there
are no significant bends in the connection from
the host pipe to the manhole. Maximum bend ≤
1.0°.
For a tight seal, the sealed area of the manhole wall (pipe connection) must be at least 110 mm.
Alternative C:
Edge of the sleeve as repair bead
Rubber jacket is seated in the center around the
steel sleeve.
The flared end of the sleeve protrudes 10-15 mm
inside the manhole and acts as a bead for repairs around the pipe connection.
14 Version:03/2015
Positioning and aligning thesleeve
Align the sleeve inside the pipe.
Turn the sleeve so that the locking screws are
roughly level on the left and right sides of the pipe.
The sleeve must always be installed perpendicular
to the axis of the pipe.
When using a spirit level, the pipe slope must be
adjustable.
Attaching and securing the clampingtools
The clamping tools on the left and right sides are identical.
However, the clamping tools are aligned differently on the left and right: oneclamping
screw points up and the other points down.
Attach the two parts of each clamping tool as
close together as possible.
Tighten the spindles to hold the clamping tools in place.
Expanding the sleeve
Start on one side.
Loosen the locking screws.
Tighten the spindle to about half way until the
sleeve is pressed against the pipe.
When expanding the sleeve, make sure it opens up evenly.
The easiest way to do this is to look at the holes on the left and right.
Continue on the other side:
Loosen the locking screws here too.
Tighten the spindle to about half way.
15 Version:03/2015
Checking the alignment in the pipe
Before the sleeve is on the pipe, check the alignment once more and correct it, if necessary.
Repositioning the clamping tools
Tighten the locking screws.
Loosen the spindles.
Reposition the two parts of each clamping tool as
close together as possible.
Fasten them with the clamping screws.
Clamping
Keep working on both sides of the sleeve
alternately:
Loosen the locking screw.
Tighten the two clamping screws
evenly. Use the holes as a guide.
Tapping in
While you are doing this, occasionally tap all the
way round the sleeve with the mallet so that the
tension is evenly distributed.
Note
The spindle is only designed for expanding the
sleeve. The sleeve is clamped using the two clamping
screws on the left and right of the tool.
16 Version:03/2015
Reaching the maximum compressionof
the seal nubs
Keep clamping until the added material (non-compressible rubber jacket + metal thickness) is less than:
Measured in liner:
8-9 mm
Measured in host pipe: 18-19 mm with no compensating
rubber
22-23 mm with 1 compensating
rubber
26-27 mm with 2 compensating rubbers
You can use the gauge from the
accessories as an aid. Set this to the
value with or without compensating
rubbers and lay it over the sleeve. If the
measuring instrument lies against it, the
maximum compression has been
reached.
Eccentric expansion of the sleeve
To compens ate for differing liner thic knesses, the
sleeve can be expanded eccentrically up to 8 mm
by tightening the inner and outer clamping screws
by different amounts.
Note: If the sleeve is expanded too eccentric ally,
the tools can become jammed.
Use the holes as a guide.
17 Version:03/2015
Removing the clampingtools
Loosen the clamping screws of the tools.
Remove the tools.
The Quick-Lock LEM >700 now forms a tight and
reliable seal.
Tightening the locking screws
Make sure that the sleeve has reached its final state.
Tighten the locking screws using the ratchet.
18 Version:03/2015
3.5 Tool maintenance
Maintenance
The spindles and clamping screws must be
treated with high-pressure lubricant (Metaflux
lubricating metal) after each use.
Conversion of the clampingtools
The clamping tool set can be used for both the Quick-Lock BIG an Quick-Lock LEM >700.
For this reason, there are side pieces in two widths.
Mount the plates on the corresponding side pieces.
Screw the clamping screws into the corresponding side piece.
Side piece for Quic k-Lock BIG (approx. 20 cm wide)
Side piece for Quic k-Lock LEM >700 (approx. 30 cm wide)
