SAFETY RULES
•Modicationofthetester,ortampering
with it’s parts is not permissible.
•Observetheinformationprintedinthe
operating instructions applicable to
operation care and maintenance.
• The tester and its accessories may
present hazards when used incorrectly
by untrained personnel or not as
directed.
• Use only the genuine Hydrajaws
accessories or ancillary equipment
listed in the operating instructions.
The model 2050 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 dial type gauge
or optional 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thestandardtesterkit.
Acomprehensiverangeofaccessories
isalsoavailable,furtherincreasingthe
scopeofpossibletestingapplications.
USE OF THE TESTER AS DIRECTED
Thetesterisintendedforusebyskilled
personnel with the appropriate training
andknowledgeoftheapplicablesafety
precautions.
GENERAL DESCRIPTION
It is essential that the
operating instructions
are read before the tester is
operated for the rst time.
Always keep these operating
instructions together with
the tester.
Ensure that the operating
instructions are with the
tester when it is given to
other persons.

TESTING PROCEDURE
6. Set the red pointer on the gauge to zero
- hold the tester by the grip handle and
proceedtoloadthefastenerbyturning
the operating handle clockwise (g 5).
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.

1. GENERAL TESTING PROCEDURE
SETTING UP THE TESTER
1 Fit the appropriate adaptor to the tester.
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legs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eachface.
Fine adjustment is available by
unscrewingthefeetbynomore
thanapproximately15mm(g 4).

It is essential when testing on ceilings
(upside down) and/or vertically, that a
safety line is attached from the eyehook
on tester body 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 using the tester.
CAUTION!
Holdthefastenersecurelybythegrip
handle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.

2.1 THE BOLT TEST ADAPTOR
Using the bolt test adaptor directly
Adjusting the handle position
Using the integrated nut
Using the bolt test adaptor with the slotted button adaptor
ForM16nuts,thebolttesteradaptor(a)
directly engages the nut (b) in the pulling
jaw (g 9).
Mount the Locking adaptor into the tester
(see Section 1 General testing procedure).
Then thread the bolt tester adaptor into the
tester body (g 10).

Mount the locking adaptor into the tester
(see Section 1 General testing procedure).
Then thread the bolt tester adaptor into the
tester body (g 10).
The threaded button adaptor (a) threads
ontothexing(c) and then slots into the
bolt tester adaptor (b) (g 12).Ensurethe
button adaptor has at least 2 complete
threadturnsonthexingandissecure.

beusedwitha24mmratchetspannerfor
betteraccessinconnedspacesandfor
easier operation (g 6).
Removethehandlesbyunscrewingfrom
the base using the 10mm wrench (g 7).
Ensurewhenre-attachinghandlesthat
they are tight on and secure.
Thetoppartoftheunitcanberotatedif
the handle or gauge 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 (g 8).

3.2 TESTING DOWELS
3.3 TESTING ANCHOR BOLTS
(MECHANICAL OR CHEMICAL)
Mount the locking adaptor into the tester (see Section 1 General testing procedure).
Thread the bolt test adaptor into the tester (see section 2.1).
(see g 11) UsinganappropriateslottedbuttonadaptorifthescrewissmallerthanM16
(a). Screw a bolt onto the dowel (c) and mount the bolt adaptor (b) to the bolt head.
Oncettedsecurelycommencetesting(seeSection1Generaltestingprocedure).
Mount the threaded stud adaptor to the anchor bolt (see section 2.2).
Removethelockingadaptorifttedintester(seeSection1Generaltestingprocedure).
Mountthethreadedstudadaptorintothetesterensuringitisfullyengaged(g 14).
Start testing procedure (see Section 1 General testing procedure).
For testing ringbolts the Clevis adaptor is
used.
Mount the locking adaptor into the tester
(see Section 1 General testing procedure).
Then thread the clevis adaptor into the
testerbodyuntilitisfullyengaged,usinga
quarterturnforpositioning(g 16).
Removecrosspinfromtheclevisadaptor
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

Aftertheanchorhasbeensetin
accordancewiththemanufacturers
recommendations,asuitablethreaded
rod (a) is screwed into the anchor and
the adaptor (b)thentted.Thelength
ofthethreadedrodtobescrewedinto
the anchor must be at least equal to the
diameteroftheanchor(g 13).
Removethelockingadaptoriftted(see

4. CARE OF TESTER
4.1 LUBRICATION
Lubrication of rod
This is required periodically depending
on usage.
Unscrew and remove operating handle.
Take care to avoid moving the washer
andbearingbelow.Greasesurfacesand
threadsbeforere-assembly(g 18).
Oil relling
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it’sfullstrokeor
give an accurate reading on the Gauge.
Eventuallytheplungerwillstopatapprox.
3mmfromtheedgeandindicatethatoilis
too low (g 19).
(Torelloilsee4.2 oil relling
instructions).
Fig 20
Fig 21
Fig 22
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. Remove bottle cap (g 20).
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 (g 21).
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(g 22).
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.
Recommendedoil:
Light Mineral DTE Type
4.3 CALIBRATION
Fromthedateofpurchase,yourtesteriscalibratedforoneyear.Afterthistime,thetester
shouldbereturnedforcalibration.TesterswithBluetoothDigitalwillreceiveareminder
