Read and understand all of the instruc-

tions and safety information in this

manual before operating or servicing

this tool.

Strut channel and threaded rod

ends can be sharp. Gloves are

recommended when handling

these materials.

Wear eye protection when operating or

servicing this tool. Failure to wear eye

protection could result in serious eye

injury from ying debris or hydraulic oil.

SAFETY

ALERT

SYMBOL

This symbol is used to call your attention to hazards or

unsafe practices which could result in an injury or

property damage. The signal word, dened below,

indicates the severity of the hazard. The message after

the signal word provides information for preventing

or avoiding the hazard.

Immediate hazards which, if not avoided, WILL result

in severe injury or death.

Hazards which, if not avoided, COULD result in severe

injury or death.

Hazards or unsafe practices which, if not avoided, MAY

result in injury or property damage.

Skin injection hazard. Do not use

hands to check for oil leaks. Oil under

pressure easily punctures skin. If

injured, seek medical attention imme-

diately to remove oil. Failure to observe

this warning could result in serious

injury or death.

If operating the tool continuously for

more than 2 hours hearing protection

is recommended. Longterm exposure

to high noise levels could result in

hearing damage.

IMPORTANT SAFETY INFORMATION

Do not overload cart

Pinch points: Keep hands away from

the cutting unit during the shearing

process. Failure to observe this warning

could result in severe injury or death.

Rotate the Service Cart on its side.

Attach the Rigid and Swivel Casters to the bottom

shelf of the Service Cart with the included caster

mounting hardware. Torque the nuts to 25 ft lbs.

Reposition the Service Cart with casters in its

upright position.

Transporting and Storage

Remove all dies from the Cutting Unit. Lower the Rear

Rod Rest and Measurement Stop. Center both Extension

Arms; lock the arms by tightening the Rear Arm Knob

and Measurement Stop Knob.

Connecting to Power Source

Attach your 10,000 psi rated pump to the Hydraulic

Ram’s universal coupler with a similarly rated hydraulic

hose. The Service Cart has an opening in its upper

shelf for the hose to feed through if the pump is seated

on the lower shelf. Tighten the hydraulic tting and

test cycle the Cutting Unit unloaded to conrm a

proper connection.

Caster Mounting

Cart is heavy, advise having two persons when

turning cart.

Die Loading/Changeover

If a die set is already loaded in the cutting unit, pull the

Swing Arm out of the Mobile Die and rotate it onto the

Die Spacer. Pull back the End Stop and slide out the

Mobile Die within the Cassette Frame, then push the

Stationary Die forward and slide it out also. Load the

new die set in a reverse matter. Be sure to reengage the

Swing Arm before beginning cutting.

Note: if having difculty removing or inserting dies, clear

debris from the Cassette Frame die pockets.

Note: it is recommended to apply a moly-base

spray lubricant to the die and frame working surfaces

whenever changing dies.

Setting the Measurement Stop

The Measurement Stop can be set to repeatedly cut

lengths from 12 to 48 inches. Turn the Measurement

Stop Knob holding down the Extension Arm counter-

clockwise to unlock. Set stop to required cut length by

moving the arm left or right as needed, then retighten the

knob. Raise or Lower the stop such that the workpiece

being cut just makes contact.

Operation

Cutting Strut Channel

When cutting strut channel, the work piece must always

be supported by the Front Material Rest. Do not cut

total channel lengths of less than 7.5” as they cannot be

properly supported and can cause a die to fracture.

Place the workpiece on the Front Material Rest and Rear

Channel Rest (if long enough) and push through the

Stationary and Mobile dies up to the Measurement Stop

(if being used) or to desired nished length. The Rear

Rod Rest should be lowered out of the way. Activate the

hydraulic pump to begin the cut cycle. Wait for the strut

to shear then release the hydraulic pressure. The Mobile

Die will return to its original position to begin another cut.

Lower the Measurement Stop and unload the nished

workpiece, then return the stop for the next cut.

Note: cutting nished lengths of less than 2 inches may

warp the channel prole.

Note: the Rear Channel Rest was designed to support

up to 10ft workpiece lengths. Additional support may be

required when cutting lengths longer than this.

Engage caster brakes before operating unit.

When cutting short pieces of strut channel the

nished workpiece can pop out due to the shock

of the cutting cycle, always wear safety glasses.

Shearing across holes and slots can leave sharp

points on nished workpieces.

Do not cut single box strut workpieces with the

double strut dies, the dies will fail quickly.

Operation (cont’d)

Cutting Threaded Rod

Push the workpiece through the Stationary and Mobile

Dies up to the Measurement Stop (if being used) or

to desired nished length. The Rear Rod Rest can be

raised to support longer workpieces. Firmly seat the

rod against the threads of the Stationary Die and keep

the workpiece perpendicular to the dies. Activate the

hydraulic pump to begin the cut cycle. Wait for the rod

to shear then release the hydraulic pressure. The Mobile

Die will return to its original position to begin another

cut. Lower the Measurement Stop and unload the

nished workpiece, then return the stop for the next cut.

Note: The threaded rod dies have been designed so that

the nut threads onto the cut rod by hand. Thread quality,

surface nish (i.e., galvanized or plated), dirt and scale

could affect the ability of the nut to thread freely onto the

cut rod.

Filing of the rod end or use of a pliers may be necessary

if nut does not easily thread on due to these factors.

Note: The Rear Rod Rest was designed to support

single workpieces up to 10ft lengths. Additional support

may be required when cutting lengths longer than this or

multiple pieces at once.

Tip: If a nut begins to thread and locks up, tapping

it on a surface will often loosen it and allow

continued threading.

Finished workpiece length should not be less than .25”.

Operation (cont’d)

Engage caster brakes before operating unit.

Cutting Angle Iron (Steel Angles) and Rebar

Note: When cutting angle iron and rebar, the reaction

force on the ends of the workpiece can be severe.

Always use the Rear Support to secure the workpiece

when cutting angle iron and rebar. The current Rear

Channel Rest will not provide sufcient support and

damage to the Rear Channel rest will occur if not

properly supported.

Lower the Rear Channel Rest and push the angle iron

or rebar through the Rear Support and then through

the Stationary and Mobile Dies up to the measurement

stop (if being used) or to the desired nished length.

Provide support to the free end of the angle iron or rebar,

keeping it perpendicular to the dies, to prevent the piece

from falling. Activate the hydraulic pump to begin the

cut cycle. Wait for the angle iron or rebar to shear then

release the hydraulic pressure. The Mobile Die will auto-

matically return to its original position to begin another

cut. Lower the Measurement Stop and unload the n-

ished workpiece, then return the stop for the next cut.

Note: The Rear Channel Rest was designed to support

up to 10 foot workpiece lengths. Additional support may

be required when cutting lengths longer than this.

Note: Cutting angle iron and rebar will require more

frequent cleaning in the track portions of the Cassette

Frame and Die Retaining Rails. Scale on the surface

of the angle iron and rebar will fall during cutting and

accumulate in the unit. See maintenance instructions

for cleaning.

Note: To remove the Rear Support when it is not

in use, disengage the plunger by pulling up the key

ring and slide the Support Frame out. To use the Rear

Support again, lift the key ring and slide the Support

Frame into the Support Base. Release the key ring and

make sure that the Support Frame is secure in place.

When cutting short pieces of angle iron or rebar the

nished workpiece can pop out due to the shock

of the cutting cycle, always wear safety glasses.
