Built-in ‘Easi-Eort®’ technology enables
the load to be applied in a eortless and
consistent action at high loads.
The standard unit has a load capacity of
35kN (7,868lbf), and by coupling to one
of the larger bridges the load capacity is
increased to a maximum of 65kN (14,613lbf)
with the benet of an increased span.
The drop rod incorporates a primary
clevis adaptor (11) which accepts a bolt
test adaptor (13) for use with slotted
and threaded button adaptors which are
included with the kit. It also accepts the
mini-clevis adaptor (12).
The three height adjustable legs (7) oer
four height positions 30mm apart. They are
held in place with steel ball pins, and the
back two legs kept parallel by a brace (10).
The brace will extend to allow the legs to t
optional larger bridges.
The swivel feet oer 12mm of usable ne
adjustment.
The drop rod handwheel (5) is used to
secure and apply a pre-load to the xing.
The ‘Anti-rotation device’ (8) prevents the
adaptor turning during pre-load.
Load is applied with either the operating
handwheel (6) or ratchet driver (16).
The load is displayed by the rechargeable
digital gauge (3), and can be recorded by the
Hydrajaws Verify App.
Tester lanyard and ratchet tether are included
for work at height.

2.1 The M35+ is supplied with the standard bridge. If
appropriate, secure the M35+ tester to the medium
or large bridge (See Section 5 – Modular Bridges)
2.2 Ensure that the position of the Operating Nut is at the
start position. The window shows (g 2.2).
2.3 Attach the drop rod with an appropriate adaptor if
required (See Section 4 – Adaptors).
2.4 Position the tester and bridge over the xing.
2.5 Adjust the length of the adjustable legs so that all
three are in contact with the base material and the
tester is aligned and level referring to the bubble
levels on the bridge.
2.6 If required adjust the swivel feet to aid levelling.
Start by bringing both adjustment screw wheels
(2.6a) down together to the required position (2.6b).
Then screw the top wheel back up to lock into
place (2.6c).
To undo, screw the top wheel down to meet the
bottom wheel (2.6d) then move them both back up
together (2.6e).
2.7 Always ensure the leg brace is tted to give the
tester stability when under load.
2.8 Connect the adaptor to the xing.
2.9 The Anti-rotational device will prevent the adaptor
turning around the xing during pre-loading.
2.10 Switch the digital gauge on (see Rechargeable
Digital Gauge instructions – Section 6). If using the
Hydrajaws VERIFY app, connect it to the gauge.
2. GENERAL TESTING PROCEDURE — SET UP
PREPARE FOR TESTING
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.

3. GENERAL TESTING PROCEDURE — OPERATING THE TESTER
3.1 Apply a pre-load using the drop rod handwheel until a load
of up to 0.4kN (90lbf) is displayed on the gauge.
3.2 Commence applying the load to the xing by using either
the operating handwheel (up to 10kN (2,248lbf)) or the
ratchet driver in a clockwise direction and observe the
reading on the gauge until the required test load is reached.
3.3 Due to the accuracy of the digital gauge, relaxation will
occur from the required test load. An allowance of +5%
over the required load (ie. 6kN +5%= 6.3kN (1,348lbf +5%=
1,416lbf)) is accepted.
3.4 If the reading continues to relax, further investigation of the
xing would be required.
3.5 When testing is complete turn the handwheel or ratchet
driver anti-clockwise to the stop position .
3.6 If using Verify app it is important to release the pre-load
from the drop rod handwheel to enable a zero reading.
3.7 Extra Pre-load (Fixings with more displacement)
Firstly, apply higher load by using the 24mm single spanner
on the drop-rod handwheel to the main piston (up to
approximately 15kN (3,372lbf)). Then continue testing using
the ratchet driver.
By using this method, more working stroke is available by
operating the ratchet driver on the slave piston.
TESTING
When applying load, stop
when the window is fully red.
When releasing load, stop
when the window is red with a
green stripe. Do not wind further
past the white line as stated on
the inner sleeve.
DO NOT
CONTINUE TO
WIND AGAINST
THE STOPS,
OTHERWISE
DAMAGE MAY
OCCUR

mini clevis is required.
Ax to the main clevis by attaching it through
the large crosspin.
Turn and release the crosspin from the clevis
adaptor.
Press to engage the crosspin through the eye
of the anchor and turn it 90° to secure.
THE HEXAGON ADAPTOR
Suitable for testing sleeve and stud anchors.
To use the optional M24 and M30 hexagon
adaptors, rst attach the adaptor onto the rod
to be tested (g 4.8a).
Then screw on a M20 threaded adaptor on
to the thread of the hexagon (4.8b), and then
oer this in the jaws of the bolt adaptor (4.9).

BO LT ADAPTOR
Using the bolt test adaptor with the
slotted button adaptor
Using the bolt test adaptor with the
threaded button adaptor
For testing xings where a connection is made
underneath the head of the xing or anchor
the slotted button adaptor is used.
The slotted button adaptor (4.5a) slots into
the bolt tester adaptor with the aid of magnets
(4.5b) and engages the xing (4.5c).
For testing threaded xings the threaded
button adaptor is used.
The threaded button adaptor (g 4.6a) threads
on to the xing (4.5b) and then slots into the
bolt tester adaptor (4.5c).
Ensure the button adaptor has been threaded
enough that the top of the rod is ush with the
top of the xing thread.
The bolt test adaptor is utilised by attaching it
to the clevis through the crosspin.
The bolt test adaptor is used in conjunction
with the supplied slotted button and threaded
button adaptors, which are easily located into
the magnetised adaptor. Larger headed bolts
can also be directly located into the adaptor.

The Standard bridge allows for testing up 35kN
( 7,8 6 8l bf ). Its footprint allows for a span of
110mm.
SELECTING THE CORRECT BRIDGE
The modular nature of the M35+ tester allows the standard unit to be easily
extended by utilising the same legs and pins in all three bridge congurations.
5. MODULAR BRIDGES
The optional Medium bridge can test up to 65kN
(14,613lbf), with a span of 210mm.
The optional Large bridge can span 310mm and
can test loads of up to 65kN (14,613lbf).

of the Medium bridge and secure it in
place using the bridge retaining pin.
8. Unlock the two tabs to release the grip on
the legs, rotate the legs until their holes are
aligned and locked by their retaining pins,
and then lock the leg brace tabs.

15
When using the leg brace on the standard
bridge ensure that the thumbscrew on the leg
brace faces out and down from the centre of
the tester, so that it is not in the way of the
anti-rotation device.
9. Loosen the thumbscrew of the Anti-
Rotation Device.
10. Insert the drop rod up through the load cell.
11. Insert the front leg into the larger bridge
and x it to your desired height with its
retaining pin.
12. Replace the leg caps on all legs.
