LOAD SPREADING BRIDGE ASSEMBLY
The bridge has been designed specifically for the model 2008 tester and directs reaction loads away
from the fixing [Figure 3].
The lightweight aluminium load spreading bridge fits in the carry case disassembled [Figure 4]. The
bridge is simple to assemble and adjust. Three fully adjustable telescopic legs offer 11 height
positions 25mm apart [Figure 1]. The legs are held in place with steel ball pins.
The swivel feet offer 30mm of fine adjustment.
The triangular shape bridge plate is deliberately
offset to offer two different close to edge testing
distances in relationship to the fixing under test.
The tester can be secured to the bridge plate in
two positions with the supplied cap screws
[Figure 6]. Securing the tester to the plate is not
crucial when the tester is being operated in a
horizontal position however is essential when
the tester is in a vertical position or inverted.

SETTING UP FOR TEST
Assemble the load spreading bridge.
Secure the tester to the bridge if appropriate.
Position the tester and bridge over the fixing
and using the M20 connecting rod pass this
through the tester and bridge.
Connect the M20 connecting rod to fixing using
the appropriate threaded adaptor [Figure 7];
The standard tester kit features five metric
threaded adaptors:
M20>M12, M20>M16, M20>M20, M20>M24 or
M20>M30.
Note: Other metric thread sizes are available via
special order.
Imperial UNC adaptors are available from stock.
Sizes; 3/8”, ½”, 5/8", 3/4"& 1"
Install M20 adjusting nut [Figure 8] on top of
the threaded pull rod.
Adjust the 3 telescopic legs to an appropriate
height, take up any initial slack using the
threaded pull rod so that the fixing under test
remains connected with no movement between
the connecting rod nut and the top of the
tester.
Ensure the tester is level by adjusting the
swivel feet against the level bubble on the top
of the tester body [Figure 9].
Each threaded swivel foot features 30mm of
fine adjustment.
Tighten with ratchet spanner [Figure 10]

OPERATING THE TESTER
Switch the digital gauge on (see separate gauge operating instructions on page 9).
Commence applying the load to the
fixing by turning the hexagon nut on
the end of the operating piston in a
clockwise direction by hand until tight
or reading appears on gauge.
Apply load using the ratchet spanner
[Figure 11 & 12] and observe the
reading on the gauge until the
required test load is reached. This
reading could decay due to first
movement or creep on the anchor.
Continue to apply the load to the
required reading and observe that the
loading remains steady*. Should a
serious drop in the indicated load
occur again, the fixing is likely to be
insecure and should be investigated.
*DIGITAL GAUGES ARE VERY ACCURATE AND THE SECOND DECIMAL FIGURE MAY NOT
ALWAYS REMAIN STEADY
As the digital gauge is very accurate a
drop off will be noticeable but this
should stabilise after a period of time. If
the reading continues to drop off,
further investigation of the fixing would
be required.
To release the load, reverse the ratchet
ring spanner and turn the hexagon nut
anticlockwise and observe the load
reading on the gauge until it
approaches zero. Unwind the operating
nut by hand until it is resting on the
stop and unwind the adjustable nut and
remove.
DO NOT CONTINUE TO UNWIND
AGAINST THE STOP, OTHERWISE
SERIOUS DAMAGE WILL OCCUR.

CHANGING THE GAUGE BATTERY
The battery (PP3) is changed by removing the battery cover (2 x
M3 flat head screws) in base of tester. Undo battery strap and
remove battery by disconnecting. Replace battery and
reassemble connections, do not over-tighten battery strap and
replace cover [Figure 13].
CALIBRATION / REPAIR / REPLACEMENT OF GAUGE
The gauge on this unit can be removed for calibration, repair or replacement, please follow the
Instructions below:
1. Remove the front cover piece from the main case by removing the x5 M4 dome head screws with
the allen key provided. Once undone the case will simply lift off. [Figures 14, 15 & 16].
2. To remove the gauge, reach inside the case and disengage the gauge from the hydraulic coupling
by pulling the coupler connector back [Figure 17 & 18].
3. Unplug the battery by removing the battery connector [Figure 19].
4. To install the gauge, push the coupler connector back before pushing the gauge home into

OPERATING INSTRUCTIONS FOR DIGITAL GAUGE
1. Press button P to switch gauge on [Figure 21].
The preset program will be in ‘Normal rise and
fall mode’ This will give a load reading in kN
rising as the operating handle on the tester is
turned clockwise. By turning the handle anti
clockwise the load will decrease and show the
reading in kN.
2. To change mode to PEAK HOLD press ▼then P.
Display off will appear. Press ▲twice to display
MAx. Press P to display PASS. Press ▲and ▼
together until display until small vertical ↑
appears in left hand side of screen. To zero
reading press ▲and wait 2 seconds. Gauge is
now in peak hold mode and will display the
maximum load achieved and retain this even when the load has decreased.
3. To return to normal mode press ▼then P and display shows MAx. Then press ▲and display
reads OFF. Press P twice and display reads 0. Press ▲and ▼together until display reads –000
(The last digit may not read 0 due to ambient temperature.)
4. Press P to switch gauge off
The maximum load capacity of the MAN-SD1S-C transducer at the base of the gauge is 0–145kN and
the gauge should not be loaded above this figure as permanent damage will occur. Eventually the
battery will require replacement (when warning indicator comes on) and the battery fitted under the
removable cover on the back of the gauge. Replace with type PP3 9 volt unit.
INSTRUCTIONS TO ZERO GAUGE
If the gauge is reading 0.32 for example when no load is applied use the following instructions to
reset the display to zero. With gauge on press down arrow, display = PDU, Press P display = OFF,
press P display = PASS, press P display = O, press the up arrow till reading reaches number 5, press P
display = ZERO, press P, display = SET, press P =

OPERATING INSTRUCTIONS FOR OPTIONAL DIGITAL BLUETOOTH GAUGE
Hydrajaws revolutionary digital technology captures test
results using an Android OS mobile device and dedicated
software application, allowing for instant visual graphs onsite
for anchors & eyebolts. The digital system using Bluetooth
produces real time visual graphs for each test.
A button and active LED on the top of the Model 2008 tester housing indicates that the tester is
equipped with this feature [Figure 22].
To switch on the Bluetooth element simply press the button and the LED light will eliminate and
begin to flesh. Open the software application on the mobile device and select the tester gauge to
establish a connection. When a Bluetooth connection has been established the LED will become
constant.
Turn on the digital gauge as normal via the P button [Figure 24] and operate as normal. Loadings will
be visible on the tester gauge and results will be recorded on the mobile device*.
*Separate instructions for use will be
provided for Software.
The Bluetooth digital gauge can be retro fitted to a Model 2008 tester.

RE-BAR OPERATING INSTRUCTIONS MODEL 2008
1. The Model 2008 Portable Heavy Duty Tester will
accept Rebar adaptors 6mm, 8mm, 10mm,
12mm, 14mm, 16mm, 18mm, 20mm & 22mm re-
bar directly through the cylinder.
2. Place the tester and triangular load spreading
bridge directly over the re-bar by passing
through the cylinder hole.
3. Place the tapered barrel over the re-bar with the
smaller diameter to the bottom until it rests on
top of the cylinder. Insert the collet (3pcs) into
the barrel and this will sit flush or just inside [See
Figure 25 & 26].
5. Adjust the fine thread at the base of each foot
and on the triangular load spreading bridge legs
by turning each foot clockwise until all the slack
is taken up and the collet has gripped onto the
re-bar. Failure to do this procedure may result in
the tester running out of stroke. (10mm) [Figure
28].
6. Ensure the tester is level by observing the spirit
level on top of the tester case [Figure 27].
7. Operate the tester by using the M24 ratchet
spanner to the desired load. [Figure 29].
8. Once the test is complete, release the load fully and lower the threaded feet on each leg by
turning the legs anti clockwise. Full adjustment needs to be made so that the barrel can be
removed from the collet.
9. Hit the top edges of the barrel with a hammer
downwards until the collet can be removed,
further adjustment to lower the bridge legs may
be required. [Figures 30, 31 and 32].
