Hydrajaws M2000 - Using Integrated Nut in Confined Spaces

76
In conned spaces the integrated nut can
be used with a 22mm ratchet spanner for
better access in conned spaces and for
easier operation (g 5).
Remove the handles by unscrewing from
the base using the 10mm wrench (g 6).
Ensure when re-attaching handles that
they are tight on and secure.
TESTING PROCEDURE
6. Ensure the gauge is set to zero - hold
the tester and proceed to load the
fastener by turning the operating handle
clockwise (g 4).
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.

CAUTION!
Hold the fastener securely 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.

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.
If no suitable xing point is available then
attach to safety harness on personnel.
Always ensure the leg brace is tted to
give the tester vital balance and rigidity
when under load.
Adjusting the handle position (g 7)
Using the integrated nut
in conned spaces

The top part of the unit can be rotated if the gauge is 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.
