The bridge has been designed specically
for the model 2008 tester and directs
reaction loads away from the xing (g 1).
The lightweight aluminium load spreading
bridge ts in the carry case disassembled
(g 2). The bridge is simple to assemble
and adjust. Three fully adjustable telescopic
legs offer 11 height positions 25mm apart
(g 3). The legs are held in place with
steel ball pins.
The swivel feet offer 30mm of ne
adjustment.
The triangular shape bridge plate is
deliberately offset to offer two different
close to edge testing distances in
relationship to the xing under test.
The tester can be secured to the bridge
plate in two positions with the supplied
cap screws (g 4). 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.

76
Assemble the load spreading bridge.
Secure the tester to the bridge if
appropriate.
Position the tester and bridge over
the xing and using the M20 connecting
rod pass this through the tester and
bridge (g 5).
Switch the digital gauge on (see separate
gauge operating instructions in this
manual).
Commence applying the load to the xing
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 (g
10) and observe the reading on the gauge
until the required test load is reached. This
reading could decay due to rst 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 xing is likely to be
insecure and should be investigated.
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 xing 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.

WARNING
DO NOT unwind the
piston past the stop!
If after a test, the operating nut has
been unwound fully however the top
piston remains tight, untighten the
adjustable nut with the ratchet spanner.
Connect the M20 connecting rod to xing
using the appropriate threaded adaptor
(g 6).
The standard tester kit features ve 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 (g 7) 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 xing 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 (g 8).
Each threaded swivel foot features 30mm
of ne adjustment.
Tighten with ratchet spanner (g 9).

5. Re-bar operating instructions
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 ush or just inside (g 11) .
5. Adjust the ne 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) (g 12).
6. Ensure the tester is level by observing
the spirit level on top of the tester case
(g 13).
4. Eyebolt testing
1. Screw the M20 connecting rod into
the heavy duty clevis and ensure the
thread engages fully so is ush with the
block.
2. Adjust the 3 telescopic legs on the
bridge so that the pin lines up with the
eye under test. Place the pin through
the eye and secure the clevis and pin.
3. Take up any further slack by either
adjusting the thread on the feet and/or
tightening the M20 adjustable nut.
4. Apply the load by operating the ratchet
spanner clockwise observing the
reading on the gauge.
5. After the test release the load by
operating the ratchet spanner anti-
clockwise and remove the clevis
and pin.
