Special Battery Warnings:

Risk of burns; battery may explode or catch fire if mishandled.
Do not disassemble or dispose of in fire.
Use only the manufacturer-supplied 7.5 volt DC power supply and charge the

battery only in the crimping tool.
Do not heat above 60⁰C or short circuit.
Do not crush or modify.

Disposal of Battery

Description

The Electronic Crimping Tools can be used to crimp and decap standard crimp caps on

laboratory sample vials. A variety of jaw sets are offered to accommodate the most popular sizes.

Crimping Tool Setup

Please read through this entire manual to familiarize yourself with the operation of the instrument
before proceeding. Use the same degree of care as you would with any precision instrument.

Remove the instrument, power supply and cable from the shipping container.
Inspect the crimper or decapper. If there is any visible damage, contact your supplier
immediately.

Operation

Charging the Battery

The battery must be charged before the crimper or decapper can be used.
The 7.5 volt DC power supply comes with a set of clips to fit power outlets for most countries.

Slide the correct clip into the back of the power supply, and plug the supply into the power main.
Plug the power jack from the DC supply into the crimping tool. After a pause the Battery LED on

the front of the tool will begin blinking green, showing that the charging has started. After 1 to 2
hours the LED will display a steady green light, indicating that the charge is complete.

Disconnect the crimper from the charging supply.

Selecting Compatible Vials, Caps and Seals

MACHEREY-NAGEL electronic crimping and decapping tools may not be used with all-steel caps
(magnetic caps) nor with 20 mm 2-part crimp caps with steel tops (bimetal crimp caps). For these
extremely stiff crimp caps we recommend our Electronic High Power Crimping Tool 735700,
which has a fixed power supply. Aluminium caps and seals of standard size and thickness are
appropriate for the battery-powered tool.

Adjusting Electronic Crimpers for Use

The electronic crimpers must be adjusted for the vials, caps and seals that will be used. The
and adjustment buttons on the top of the crimping tool set a stop position for the motor that
drives the tool.

The adjustment of the crimping tool is effectively a height adjustment. The setting determines the
amount of compression of the cap and is very accurate. There may be some drifting over time due
to stretching or wearing-in of components of the new crimper, but generally the reproducibility of
the crimp is as good as the consistency of the vials and seals.

Select 5 or so vials, caps, and seals for the purpose of setting the crimp. Place the seal and cap
on the vial and rest the crimper on top of the cap.

Squeeze the trigger switch lightly to engage the motor. This switch must be held down until the
crimp is complete. If the switch is released early, the crimper will retract.

If the Status LED blinks amber after the cycle is complete, a fault was detected. Two yellow blinks
mean that the trigger button was released early. Three yellow blinks mean that the crimper stalled
– it was not able to deliver enough power to reach the position requested in the setting.

Check the crimped vial for satisfactory form and tightness. If the cap spins easily, press the
button two or three times. Try the new setting with a new vial and cap.

Crimping the same vial two times will not generally give the same results and sometimes will result
in vial breakage. See the section on “Troubleshooting” for more information.

Adjusting Electronic Decappers for Use

The adjustment is not very important when decapping. As shipped from the factory the decapper
should remove a cap satisfactorily.

The 11 mm and 13 mm decappers work by closing the jaws around the neck of the vial and
stripping the cap off. For the 11 mm decapper to work the glass vial must be strong enough to
resist the force applied by the decapper. In the case of inferior or soft glass or if a vial is reused
the lip of the vial may break during decapping.

To adjust the 11 mm decapper make sure that the stroke is long enough to remove the cap.
The 20 mm decapper works by pinching the sides of the cap with the decapper jaws and pushing

out the glass. The pinching action starts to pull the cap off, and the force of the decapper does
the rest of the work.

To adjust the 20 mm decapper, just make sure that the stroke is long enough to remove the cap.

When to Recharge the Battery

The 6.4 volt battery pack for the electronic crimper uses lithium ion cells. After receiving a full
battery charge the electronic crimper or decapper will normally crimp several hundred vials,
depending on the age of the battery and the requirements of the seal and cap chosen.

Unless the crimper is used for a large number of vials each day it is not necessary to recharge
the battery every night. The lithium ion pack will retain its charge for many weeks without losing
its charge.

The Battery LED will blink amber during the crimp stroke, if the battery needs charging.
The lithium ion battery pack is expected to last at least 1500 charges. The pack should not be

removed from the crimping tool unless it is due for replacement.
See the instructions on page 5, “Charging the Battery” for further instructions.

Reset

Reset

To press the reset button use the end of a small tool to access the recessed button.
Single Reset: Pressing the reset button one time causes the position sensor to be set to zero

and resets the processor.
Factory Reset: This requires pressing the reset button while both the and buttons are also

down. The green LED will blink one time and the crimping tool is returned to the factory setting.
This is useful to find a consistent starting point for adjusting the crimping tool, if it is far out of
adjustment.

Troubleshooting, Maintenance, and Repair

General Maintenance

The electronic crimping tools do not contain user serviceable parts except for the battery pack.

When cleaning or replacing the battery make sure to keep fingers away from the jaws!

Cleaning

The crimping tool may not be immersed in water or solvent. The outside of the case may be
cleaned with an ordinary detergent and wiped off with a damp rag. Care should be taken not to
get the electronics, the battery, or the battery connections wet.

Avoid permitting metal parts of the crimping tool come into contact with corrosive material
during use. If they do, try to wipe them clean with a suitable mild neutralizing solution.

Battery Replacement

Use only the specified 6.4 volt replacement battery pack, part number 735500. Use of
other batteries may cause fire during charging or use.
