PREPARATION FOR INITIAL USE
On hand pump units, replace the plastic shipping plug
on top of the pump assembly with the breather vent. No
other special unpacking or assembly requirements are
required on either unit prior to usage.
Each unit should be inspected to assure it was not
damaged in shipping and doesn't contain packing debris.
CHECK HYDRAULIC POWER
SOURCE
(POWER UNIT MODEL ONLY)
1. Using a calibrated flow meter and pressure gauge,
check that the hydraulic power source develops a
flow of 4-10 GPM/15-38 LPM. Do Not exceed 140
bar/2000 psi.
2. Ensure the hydraulic power source has a relief valve
set to open at 2200-2300 psi/151-158 bar.
3. Ensure that the power source return pressure does
not exceed 250 psi/17 bar.
4. Check that the hydraulic circuit matches the tool for
open-center (OC) operation.
CHECK TOOL
1. Make sure all tool accessories are correctly installed.
Failure to install tool accessories properly can result
in damage to the tool or personal injury.
2. There should be no signs of leaks.
3. The tool should be clean, with all fittings and
fasteners tight.
CHECK CONTROL MECHANISM
Hand Pump Models
On hand pump models, check that the directional
control valve operates freely from the neutral position
to the forward position and then to the rear position. In
each position, work the lever to ensure movement of the
cylinders is free of binding and that the hydraulics are
performing as intended.
Power Unit Models
On power unit models, check that the directional
control valve operates freely from the neutral position
to the forward position and then through the neutral and
rearward positions.
CONNECT HOSES
1. Wipe all hose couplers with a clean lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power
source to the hose couplers on the weld shear. It
is a good practice to connect the return hose first

and disconnect it last to minimize or avoid trapped
pressure within the cylinders.
3. Observe flow indicators stamped on hose couplers
to be sure that oil will flow in the proper direction.
The female coupler is the inlet coupler.
Note: The pressure increase in uncoupled hoses
left in the sun may result in making them difficult to
connect. When possible, connect the free ends of
operating hoses together.
OPERATING PROCEDURES
POWER UNIT AND HAND PUMP MODELS
CHECKING OPERATION AND
PERFORMANCE
1. Observe all safety precautions.
2. Remove any debris and burrs from the rail joint that
may interfere with the weld shear cutters.
3. Place the weld shear on the rail, over the location to
be welded.
4. Adjust the height of the four roller pivots. The pivots
must, once pivoted, be placed under the rail head
with a minimum of clearance to avoid any forcing
during the forward movement of the cutters. This
adjustment is done with the 4 hex nuts.
5. On the power unit model, move the hydraulic circuit
control valve to the "ON" position.
6. On the Weld Shear, move the directional control
valve lever to the forward position so that the shear
blade advances. (On hand pump versions, the shear
blade will not advance or retract without pumping
the lever) Check that the shear blade advances
without binding. With the cylinders fully extended,
there should be a gap of 1/32-1/16 inch between
the two shear blades. If this gap is not correct, do
not use the weld shear and have it serviced by an
authorized and certified dealer. If the gap is correct,
retract the shear blade to its most rearward position
by moving the control lever to the rearward position.
The shear blades should now be as far apart as the
tool will permit.
7. Remove the weld shear from the rail.
CUTTING PROCEDURE
1. Proceed with the preparations for welding and put
the molds and accessories in their place.
2. Pour the weld.
3. As soon as permitted by the mold manufacturer's
