The tester is intended for use by skilled personnel with the appropriate training
and knowledge of the applicable safety precautions.
The Hydrajaws M35+ Dual Load Capacity Modular Pull Tester is designed for
establishing linear loading of mechanical and resin anchors, eye type anchors,
threaded bar and structural bolts and fixings to a load of 35kN (7,868lbf) with
the standard bridge or maximum 65kN (14,613lbf) with medium or large bridge.
SAFETY RULES
Modication of the tester, or tampering with
its 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.
It is essential that the
operating instructions
are read before the tester is operated
for the first 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.

The M35+ is a compact, lightweight, dual
load capacity modular digital pull tester
designed to test eye bolts and anchors.
1. OVERVIEW: M35+ DUAL LOAD MODULAR PULL TESTER
Featuring Easi-Eort® technology, the M35+ can increase
testing frequency whilst reducing operator eort.

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

For testing ring bolts the Clevis adaptor is
used.
4. ADAPTORS
CLEVIS
MINI-CLEVIS
For smaller diameter fall arrest eye bolts, the
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).

The clevis can be rotated in 90° increments to
better engage an anchor (g 4.2).
