The M2000 pull-out tester is
a purpose made system for testing
xings, fasteners and anchors. It
consists of a mechanical screw
arrangement acting through a
hydraulic load cell, which measures
the load applied to the xing directly.
The resulting load value is then
indicated on the digital gauge.
The tester has a built in movement
indicator scale 50mm to show “rst
movement” on the xing prior to the
test load being applied. The tester and
bridge are supplied as an integral part
of all the M2000 tester kit ranges.
A comprehensive range of accessories
is also available, further increasing the
scope of possible testing applications.

Example shown is a bolt tester adaptor.
(For tting of other adaptors please see
individual instructions in this manual).
2. The tester is supplied with a locking
adaptor tted into the tester body.
This locking adaptor can be removed
for tting of different adaptors by using
the 3mm Ball Driver. When replacing
back in ensure it is fully engaged into
the tester body before tightening
(g 1). Thread the bolt tester adaptor
into this, until it is fully engaged, using
a quarter turn for position (g 2).
3. Make nal adjustments so that the bolt
tester adaptor, tester and xing are
aligned (g 3).
4. Position the tester so that the gauge
can be easily read.
5. Adjust the length of the telescopic legs
(see section 8) so that all three are in
contact with the base material and the
load spreading bridge is aligned and
level by referring to the bubble levels on
the bridge.

In conned spaces the integrated nut can
be used with a 22mm ratchet spanner for
better access in conned spaces and for
easier operation (g 5).
Remove the handles by unscrewing from
the base using the 10mm wrench (g 6).
Ensure when re-attaching handles that
they are tight on and secure.
TESTING PROCEDURE
6. Ensure the gauge is set to zero - hold
the tester and proceed to load the
fastener by turning the operating handle
clockwise (g 4).
7. Increase the load until the required
test load is attained. Hold this load and
observe any falling back of the readings
which would indicate movement and
possible failure of the fastener. Record
the satisfactory result.
8. Release the load on the fastener
by turning the operating handle
anti-clockwise and allowing the test
jaw to return to the original position.
9. Remove the tester and bolt tester
adaptor.
Fig 5
CAUTION!
Hold the fastener securely as long as
the fastener is under load. When the
load increases, note the reading on
the displacement scale on the tester.
Indication of failure of the fastener may
be obtained by comparing the current
reading with the original reading.
Fig 4
Fig 6
It is recommended when testing
on ceilings (inverted) and/or
vertically, that a safety line is
attached around the tester body
(either through the loop hole or through the
middle) and attached to a suitable solid xing
point. This will stop the tester falling and
prevent injury to personnel and/or damage
to test unit.
If no suitable xing point is available then
attach to safety harness on personnel.
Always ensure the leg brace is tted to
give the tester vital balance and rigidity
when under load.
Adjusting the handle position (g 7)
Using the integrated nut
in conned spaces
Fig 7
The top part of the unit can be rotated if the gauge is becoming obstructed by the unit legs
or other objects.
This is achieved by loosening the three grub screws (a) on the body using the allen key
provided. Rotate the top until the handle and gauge are clear of obstacles and re-tighten
the screws.

3. SCAFFOLD TESTER KIT
The Hydrajaws Test meter is part of a
purpose made system for testing xings
and measures the load supplied. The
Scaffold Tester Kit has accessories
designed to test Scaffold Anchors and
Ringbolts to the requirements of the
guidance note TG4:17 issued by National
Access and Scaffolding Confederation
(NASC) and the Construction Fixings
Association (CFA).
The Tester is factory assembled with the
bolt tester adaptor screwed into the M12
locking adaptor located in the Tester jaw.
Height can be adjusted using the swivel
feet (20mm).

TESTING OF M16 DROP IN SCAFFOLD TIE ANCHORS
Fit the M16 hexagon setscrew to the anchor, ensuring at least two complete turns for
ample thread engagement. Offer Tester with bridge to the hexagon head of the setscrew
and engage head in bolt tester adaptor jaw. Make adjustment on each swivel foot by
unscrewing from the telescopic legs so that each foot is resting on the material around the
anchor and the bridge is square and level. Check that the gauge is registering zero.
Commence the test by turning the operating handle on the Tester clockwise and observe
the gauge as the load on the anchor is increasing. Continue applying the load until the
proof test load is reached. Stop applying the load and observe if the reading falls back. If
the fall back is minimal, apply the load again until reading is at the test load required and
leave the test load in place for approximately 10 seconds.
Should the reading not reach the maximum test load requirement, or the
operating handle has to be turned to maintain the load, it is certain that the anchor will
have failed the test.

1312
TESTING OF EYE TYPE ANCHORS
Unscrew the bolt tester adaptor from the M12 locking adaptor in the Tester jaw and
replace it with the ringbolt adaptor clevis. Ensure that at least 2 complete clockwise turns
are made to safely engage the threads. Remove crosspin from the clevis and offer the
Tester and bridge to engage eye of the anchor in the clevis. Some adjustment will be
required on the swivel feet, so that this t is achieved, push clevis pin through the clevis
and eyebolt, ensuring that the ball on the pin clicks into place, having passed through the
second fork. Commence the test as described for drop in anchors.
Note: Longer Scaffold Eyebolts used in timber frame construction can be tested. But
extra long extension legs are required – not supplied in standard kit.
The new NASC/CFA Guidance Note TG4:17* “Anchorage Systems for Scaffolding” sets
out requirements for PRELIMINARY TESTS of scaffold anchors (to check the suitability
and allowable loads of an anchor type in a particular base material) and PROOF TESTS
(sample tests to check that anchors have been installed correctly – to be carried out on
all jobs).
The new Proof Load testing requirement is for a tensile test of 1.5 x the design load.
The Hydrajaws Scaffold Tester Kit will test all of these types to a maximum tensile load
of 20kN. TG4:17 also describes six types of anchor most commonly used for anchoring
scaffold ties. The Hydrajaws Scaffold Tester Kit will test all of these types to a maximum
tensile load of 25kN.

Place the bridge over the eyebolt to be tested. Locate the clevis on the eyebolt and t the
cross pin through the clevis and eyebolt, ensuring that the ball on the pin clicks into place,
having passed through the second fork (see section 2.5 The Clevis Adaptor).
Adjust the swivel feet by unscrewing from the telescopic leg, so that each foot is resting
on the material around the eyebolt and the bridge is square and level. Fit a protection plate
(not supplied by Hydrajaws) between wall and bridge feet if necessary, to protect
soft decorative nishes. Check that the gauge is reading zero.
Commence the test by turning the operating handle on the tester clockwise and observe
the gauge as the load on the eyebolt is increasing. Continue applying the load until the
proof test load of 6kN* is reached. Stop applying the load and observe if the reading falls
back.
If the fall back is minimal, apply the load again until reading is at the proof test load and the
structural anchorage should then sustain the force for a minimum of 60 seconds.
Follow the same setting up procedure as for Safety Harness Eyebolt test, and apply the
load gradually until the required proof load of 2.5kN* is reached or failure occurs. Observe
if the hook withdraws from the structure or the test load cannot be achieved. This would be
considered a failure and must be taken out of service.

SITE TESTING OF
WALL TIES
The purpose of carrying out site tests on
wall ties is either as part of a site survey to
investigate the suitability of the base
material for the use of a particular tie or
during the installation of the ties to verify
the quality of the installation.
OPTIONAL ADAPTORS
Optional adaptors are available for non-threaded ties.
For example, the Helix wall tie (pictured on right) has a
special adaptor to enable testing.
Please contact us for information on our range of
special adaptors.
Fig 25
Fig 24
In accordance with the BBA recommendation on Remedial wall ties it is required that
the rst 3 ties in a building should be tested followed by 1 tie in every 20 installed. BRE
Digest 401 ‘Replacing wall ties’ species that the inner end of the rst 20 ties installed on
a contract should be all proof tested and that a reducing rate of testing is required for the
remaining ties, for 21 to 250 ties 10% should be tested, for 251 to 1000 ties 5% should be
tested and for more than 1000 ties 2.5% should be tested.
LOAD PROCEDURE
Generally the loading procedure for
testing wall ties is the same for both ends
of wall ties regardless of whether they are
mechanical and chemical xings, so the
loading procedures which follow. Connect
the wall tie adaptor complete with the M12
threaded button adaptor to the end of the
wall tie, taking care not to tighten the outer
leaf expansion nut (g 24).
With the test meter securely attached to
the Bridge, adjusting the length of the legs
on the loading bridge and the position of
the button adaptor if necessary, pass the
adaptors through the keyhole slot in
the loading bridge and ensure that the
button adaptor is centred in the test
meter (g 25).
Use the adjustable swivel feet to take up
the slack in the system and to ensure that
the test meter is axially aligned with the
wall tie under test.
DO NOT LOAD THE
TIE WITH THE
SWIVEL FEET.

recommendation). Some indication of the displacement of the tie can be obtained by
comparing the reading form the displacement scaled while the xing is under load with the
rst reading noted. To release the load rotate the handle anti-clockwise and push down
until the original position is resumed. Lift the test meter off the stud adaptor and unscrew
the adaptor and studding.
PROCEDURE, INNER LEAF
Install the tie into the inner leaf in accordance with the method statement appropriate
to the wall tie being used. If appropriate leave the resin mortar to cure for at least the
recommended curing time. Load the tie in accordance with the procedure given above.
If the displacement of the tie is judged to be excessive then the quality of the x into the
base material is suspect. Remove the testing assembly and complete the installation
of the tie in accordance with the appropriate method statement.
PROCEDURE, OUTER LEAF, MECHANICAL CONNECTIONS
It is not possible to test the outer leaf in isolation on a normally installed tie.
For inset wall ties - ensure width of hole (a)
is wide enough to accommodate the wall
tie adaptor and is set deep enough (b).
NOW AVAILABLE: WALL TIE TESTER KIT MK 2
The Hydrajaws Wall Tie Tester Kit Mk2 is used for testing all types
of remedial wall tie to meet the requirements of DD140. It is used
with appropriate adaptor and mounts direct to tester.
The Mk2 Kit comes with M5 and M6 threaded rod adaptors and a
selection of adaptors are available to suit a wide range of wall ties.

6. MATERIAL BOND TESTER KIT
Procedure for preparing samples for pull-off testing:
1. Clean the steel dollies (degrease and grit blast unless
otherwise stated). This will help to prevent interfacial
failures at the dolly interface.
2. For concrete substrates drill through the repair system
with diamond core drill at (90±)º to the surface into the
test surface by ~5mm or more.
This ensures a consistent bond area and will therefore
help reduce variations in the test results.
3. Clean the substrate test surface as recommended by
the manufacturer.
4. Mix the adhesive as recommended by the adhesive
supplier and add 1% by weight of ballotini (usually
0.5mm unless stated otherwise).
Adding ballotini will reduce alignment errors and
therefore help reduce variations in the test results.
5. Apply adhesive to steel dolly.

ON SITE PULL-OFF METHOD
Equipment that may be required in
addition to the standard kit contents:
• Adhesive • Spatula
• Bondline spacers -
i.e.ballotini (glass spheres)
• Diamond-coated core drill
The bonding strengths of a wide and
varied range of materials including
concrete, screeds, repair mortars, epoxy
resin coatings, laminates, plastics,
paints and enamels may be accurately
determined using the Hydrajaws Material
Bond Tester.
Adequate direct tensile strength or
bonding strength between two layers is
important if repairs to concrete structures
or additional overlays and screeding on
existing concrete is to be structurally
sound.
The pull-off test as a means of projecting
the compressive strength of concrete
and other materials involves bonding
a circular steel disc to the surface by
means of an epoxy resin adhesive.
KIT CONTENTS:
A controlled tensile force is then applied to the disc, and as the strength of the bond is
greater than that of the material under stress it will eventually fail in tension. From the
area of the disc and the force applied at failure it is possible to calculate a nominal tensile
strength for the material.

DO NOT ‘seat’ the dolly by twisting it into position. If the dolly is twisted into position it
will increase the likelihood of interfacial failures.
8. Remove excess adhesive from around the edge of the dolly without disturbing its
position (g 26c). This ensures a consistent bond area and will therefore help reduce
variations in the test results. If working on a vertical or overhead surface, ensure the
dollies are held rmly in position until the adhesive has cured.
9. Connect centering plug to disc using the 8mm thread and hand tighten until bottom is
ush with top disc (g 27a).
10. Lower load stool centre hole over centering plug and adjust the 3 screws until top of
plug is ush and level with top of stool. It is essential that this levelling is carried out
carefully to ensure a square and smooth pull through the stool. The load applied to the
centre of the dolly should be at an angle of 90º±1 (g 27b).
11. Slide Tester over adaptor on top of plug and t 22mm socket and ratchet to the
operating nut (g 28). Secure equipment so that it does not move during testing.
This will cause excess misalignment which will reduce pull-off strengths.
12. Operate ratchet in a clockwise direction until required loading is obtained or bonding
breaks. Record test temperature, failure load and failure mode (g 29) (Record mixed
failure modes in percentages of bond area, i.e. 90% substrate failure, 10% cohesive
failure). Maximum loading achieved will be shown by red indicator pointer. Use this
reading to calculate the bond strength Mpa from the chart on page 20.

IMPORTANT! A low reading will be obtained if:
• The pull-off tester is misaligned and not perpendicular to the specimen
• The specimen is misaligned and not perpendicular to the pull-off tester
• The bondline is not of uniform thickness (0.5mm)
• A sudden or erratic loading is applied.
Note: This information is for guidance only. Please also refer to adhesive manufacturer’s

Pyramid Stool
Telescopic 270
Telescopic
600
Hydrajaws offer three optional load
spreading bridges, a pyramid stool with
threaded legs and a 270mm or 600mm
wider span bridge with telescopic legs.
These are designed to attach easily to
the Hydrajaws M2000 Tester.
To install, rst remove any existing load
spreading bridge by removing the two
positioning screws using the 3mm ball
driver. Use the same screws to secure
the tester to the optional bridge.
The 270mm and 600mm load
spreading bridges can be installed so
the tester is operated in two different
positions as illustrated. The legs are
fully adjustable to suit the testing
application.
A thread adaptor coupler is also
supplied to extend the accessory in
use. The Pyramid stool is supplied
with an extended bolt test adaptor.
To adjust leg height:
- pull out pin.
- adjust leg to desired
height.
- line up hole and
insert pin until it clicks
into place.
Fine adjustment can be made by
unscrewing the feet by no more than
approximately 15mm.
Caution:
If light is visible through the bottom
indicator holes then the leg has
been unscrewed too far. Dont
expose more than 15mm of thread.

NOTE: A tester with a xed gauge cannot
be lled with oil by the operator.
1. Remove the bridge and all accessories.
2. Secure the tester (e.g. in a vice or other
suitable holding device if on-site) with
the coupler in the vertical position.
3. Connect the oil bottle via the quick
release coupler.
4. Loosen bottle cap (Fig 32).
5. Turn the handle anti-clockwise a few
turns then using the piston key provided
insert this into the groove on the piston.
Ensure the piston key outer slot is
nearer the piston body (Fig 33).
6. Force any air out of the system by
pushing the piston in fully then pull on
the piston key and handle until 10mm
away from the inside of the slot. This
will draw oil from the bottle (Fig 34).
7. Push the piston back in fully, pull out
again and repeat until all the air bubbles
are expelled into the bottle, the oil is
replenished, and piston is 10mm from
face of the body.
8. Remove oil bottle.
Ensure not to pull the piston
out further than 15mm.

Connecting and disconnecting Gauges
from the Tester body will eventually use up
the spare oil capacity and will not allow the
tester plunger to travel its full stroke or give
an accurate reading on the Gauge.
Check the oil
level frequently or
eventually the plunger
will stop at approx.
3mm from the edge
and the tester will not
function correctly.
