INTEGRAL HYDRAULIC NUT SPLITTERS
6
USING THE NS12TI/NS15TI/NS20TI
Position the tool as per Section 3.6.
When the pump is operated the piston and the Cutting
Tip will advance. Ensure the tool is flat against the flange
and the Cutting Tip perpendicular to the nut throughout
the operation. Slowly actuate the Nut Splitter to advance
the Cutting Tip against a flat of the nut and increase the
pressure until the nut splits.
Releasing the pump will depressurise the cylinder and
cause it to retract under the force of its internal spring.
It is likely that the nut will require a second split to fully
remove the nut from the stud. Ideally a second split
should be carried out at 180° to the first cut, splitting the
nut in half to enable removal.
After the nut has been split, always check the Cutting Tip
for damage and replace if required before positioning the
tool on another nut.
CAUTION: Split nuts often have sharp edges
and should be handled with great care.
3.4
HANDLE
The handle can be swivelled around the central axis of the
tool, to improve access to the nut and allow the tool to be
easily held in the vertical or horizontal orientation.
3.5
SAFETY LANYARD
The NS tools are supplied with a secure anchor point and
a safety lanyard. The safety lanyard should be used to
minimise the risks associated with the tool dropping.
Attach one end of the safety lanyard to the tool using
the supplied shackle. The other end of the safety lanyard
should be fixed to a secure point close to the work-site
using an appropriate shackle.
Avoid using the safety lanyard as a means for picking up
or carrying the tool. Do not fix the safety lanyard to the
handle.
3.3
HYDRAULIC TOOL OPERATION
Prior to operation, ensure the air-vent in the integral hand
pump is not obstructed. Any obstruction in the air-vent
can cause a vacuum in the system which can limit the
cylinder’s travel.
The NS12TI, NS15TI and NS20TI Nut Splitter use an
integral hydraulic pump to drive the cylinder and advance
the Cutting Tip to split the nut. The hydraulic pressure
is applied using the integrated hand pump, enabling
accurate control of the force applied.
The integral hand pump has a control lever which allows
the user to select advance (+) or retract (-)
ACTUATING THE NS12TI/NS15TI/NS20TI
When advance (+) is selected, pumping the handle will
advance the piston with the Cutting Tip and split the nut.
RETRACTING THE NS12TI/NS15TI/NS20TI
Selecting Retract (-) will depressurise the cylinder and
cause it to retract under the force of its internal spring.
The handle doesn’t need to be pumped to retract the
cylinder.
