B.2 Safe Operaon of Equipment
Double E Company designs and manufactures core cuutters with maximum safety in
mind. Please take careful note of the following rules for safe operation:
· Double E recommends always using the core cuer carefully without abusing it. Avoid strong
collisions and/or accidental impacts with foreign bodies. These collisions can damage the
machines internal and external parts.
· There is risk of injury or pinching from the rotaon of the cuer during cung. Keep
sucient distance during cung and do not touch any part of the moving machine during
rotaon.
· Do not wear loose hair or clothing near rotang parts for risk of entanglement.
· Do not use the core cuer in working condions dierent than stated in the specicaons
table or on any notes on the assembly drawing.
· Do not exceed the operang loads of the machine as specied on the customer quotaon
and/or assembly drawing. This voids the warranty and can be unsafe.
· Make sure all fasteners and guards are in place before operaon.
All replacement parts on this core cuer should be original equipment supplied by the
DoubleE Company.

D. OPERATING INSTRUCTIONS
D.1 Installing Core Adapters
Do not perform any installation while the main switch is on
Install the sliding core adapter (13), the staonary core adapter (14), the spacer (15), and anvil
(16) on the core support bar. Use the washer (17) and athead socket screw (18) to clamp the
pieces on the bar securely. Insure the sliding and staonary core adapters rotate freely.
HINT: For quicker diameter change, leave the 6” and 3” sliding adapters on the bar at all
mes.
Slide a core onto the support bar. Be sure the bar is level with the core resng on the drive
rolls. If not, raise or lower the le end of the bar as necessary. Lock it in place with the
clamping lever.
Be careful working in the area around the guarded cung blade.

D.2 Seng Cung Assembly Height
Do not perform any installation while the main switch is on.
With the core sll on the bar, loosen bolt 7 and adjust the height so the cung arm 6 is
horizontal when the blade contacts the core. When completed, reghten olt 7 to lock the
assembly at the correct height.

www.ee-co.com M70-100 Manual V2 Page 10 of 22
D.3 Adjusng Core Stops
Do not perform any installation while the main switch is on.
The core stop help keep the core from bouncing when cut. Loosen lever 8 to allow the stopsto
slide. Slide arm 17 so the bearing is lightly touching the core above it’s center point. Tighten
lever 8.

www.ee-co.com M70-100 Manual V2 Page 11 of 22
D.4 Adjusng Core Length Bar
Do not perform any installation while the main switch is on.
The core length bar (11) slides to allow seng the core length. It is provided with a rule and is
locked with lever 10. The stop (12) is located on the right and should be ipped out of the way
before the cut is made to prevent jamming the cut core.

www.ee-co.com M70-100 Manual V2 Page 12 of 22
D.5 Making the Cut
Do not perform any installation while the main switch is on.
Once the core is loaded on the support bar and the adjustments have been made, the cung
process is easy. Be sure the main switch is set to on and the Emergency stop switch is not
depressed. Pressing the Green buon while pulling evenly down on the cung handle will
start the core rotang. Pulling down to force the knife through the core will complete the cut.

F. MAINTENANCE
F.1 Roune Inspecon
Perform roune inspecon weekly. Roune inspecon can usually be accomplished without disassembly or removal of
parts from the machine. The purpose of roune inspecon is to ensure that the machine is funconing properly prior
to being used. Check the electrical system to ensure that the machine can not start without intenon and check the
funconing of the emergency stop buon. Ensure that all fasteners are ghtened properly and are not missing. Check for
worn or broken parts; if necessary, replace. Check the rubber drive rollers for dirt and dust and clean if necessary.
F.2 Annual Maintenance
Perform annual inspecon/maintenance yearly. Ensure that all fasteners are ghtened properly and that the safety
systems work properly. The machine condion should be evaluated and any worn or dirty parts replaced or cleaned. The
area around the machine should be kept free of dust and dirt so the operator can freely move without risk of tripping
over cut cores or components.
F.3 Non-Roune Maintenance
If the product is used under normal condions and inspected regularly, it is rare that any non-roune or extraordinary
maintenance will be needed. In the event that it is necessary, it is recommended that you contact Double E Company
Technical Support at 508-588-8099 extension 571.
F.4 Decomissioning
If the product is withdrawn or removed from service, it is necessary to make all at-risk components harmless through
proper demolion. These operaons must be carried out in accordance with the provisions exisng in the naon in which
the product will be disposed.

G. TROUBLESHOOTING
G.1 Mechanical Troubleshoong
I. Core is not completely cut or burrs on the ID of the cut
Possible Causes:
1. Anvil is worn out meaning the notch is greater then the 1mm depth set at the factory.
How to Proceed:
Rotate or replace the anvil
2. The inside core diameter is larger than the allowable core tolerance (core tolerance
is + / - 0.3 mm).
Consequently, the core is not properly gripped during the cung
operaon.
How to Proceed:
If the customer’s cores are out of tolerance by more than + / - 0.3 mm, the cores ID should be
measured precisely
and a new anvil should be ordered according to the actual size. Alternavely,
adjust the ball catches on the adapters to beer grip the core.
3. Knife does not go down completely and consequently it doesn’t cut a core completely.
How to Proceed:
Loosen the height locking handle and posion the cuer head properly so it can completely
penetrate the core. Reghten the locking handle

www.ee-co.com M70-100 Manual V2 Page 16 of 22
4. Knife blade is worn out, blunt or it is
jagged.
How to Proceed:
Rotate or replace the worn out knife blade with a new
one.
II. Screw Cung
Possible Causes:
1. The Core Support Bar is not level or straight
How to Proceed:
Conrm that the core bar assembly is not bent. Adjust the horizontal locaon by loosening
and
adjusng the core bar assembly support to the center of the gear drive. If the core bar assembly is
bent, aempt to straighten it. If
this procedure fails, replace the core bar assembly .
During the cung operaon, the core moves parallel to its axis. As a result, the knofe does not cut through the core,
rather it makes a cut similar in appearance to a screw thread
III. Diculty pung core onto Core Support Bar
Possible Causes:
1. The inside diameter of a core is too small (core ID is out of the required tolerance + / - 0.3mm).
How to Proceed:
Measure the core ID the customer uses and order a new set of core adapters according to
customer’s
needs.

www.ee-co.com M70-100 Manual V2 Page 17 of 22
IV. Core is not in proper contact with the drive rollers
Possible Causes:
1. The core bar assembly of the core cuer is not parallel to the machine frame .
How to Proceed:
Loosen the core bar assembly fastener and adjust to a level posion, placing it in parallel to the
machine frame, ghten fastener.
This operaon should be carried out with a core placed on the
machine.
As a result the core slides on the drive rollers. Aer cung a core, a secon of the original core stays on the
machine
and moves to the right or to the le.

G.1 Electrical Troubleshoong
I. Motor does not work aer turning on the machine and pressing the START buon while
pulling the cung arm assembly down
Possible Causes:
1. Micro-switch placed inside the knife cover K2 is damaged.
How to Proceed:
Check if the micro-switch is jammed. If it is jammed remove the two screws and micro- switch cover
and adjust
its posion so it does not jam.
If this procedure does not yield sasfactory results, replace the micro - switch.
2. Current protecon breaker inside the electrical box has been acvated.
How to Proceed:
Press the black reset switch on the Q1 circuit breaker.
3. The S1 contactor is damaged.
How to Proceed:
Check with a multi-meter if the contacts operate properly. Check with a multi-meter if contactor coil
is
damaged..
5. EMERGENCY STOP switch, contact K1 - (red contact) - is damaged.
How to Proceed:
Check with a multi-meter if the contacts operate properly. If needed replace them.
6. Power Supply is damaged or there is short-circuit in the 24VDC circuit.
How to Proceed:
Check if there is 24VDC at power supply output and if the green diode is illuminated.
If the diode is not illuminated, check if 120 VAC is at the power supply input. If it is present, the
power supply is damaged.
If the green LED is blinking, the 24VDC circuit has an electrical short
present. Trace the short and repair
