Safety
Principle Safety Advise
Only qualified personnel as stated by the machines instruction manual and user guidelines should operate the
machine. All machine safety guidelines and requirements are to be followed.
All company and machine safety regulations are to be followed.
The following pages describe the basic safety instructions and the safety regulations. With these safety
instructions no claim is made to the completeness.
Danger when Operating the System or Subassemblies
reCool®is constructed according to the latest state-of-the-art and the recognized safety regulations. Danger to the
operator or to others, or damage to the system or other material damage through improper handling or use can
occur. The system must only be operated:
•for the intended purpose.
•in a safe condition.
Faults which can affect safety must be eliminated immediately.
Appropriate Use
reCool®is exclusively for the clamping of tools (cutters and drills) to be used in static tools. The machine must be
equipped with external flood cooling ports (used as peripheral cooling).
All other use is considered inappropriate. Consequently, REGO-FIX does not take any responsibility for damage
caused by inappropriate use.
Appropriate use means, among other things:
•To follow all recommendations mentioned in the Operating Instructions.
•To adhere to the inspection and maintenance requirements.
Inappropriate Use
We do not take any responsibility for damages caused by inappropriate use.
Inappropriate use includes, but is not limited to:
•The use of a defective reCool®.
•Operation of reCool®static on driven tools.
•Use of coolant pipes and fittings of other manufacturers.
•Use of coolant pipes and fittings for ≤100 bar with more coolant pressure.

2
Maintenance, Repair, Fault elimination
•The mandatory adjustment, maintenance and inspection work should be performed at the specified
maintenance intervals.
•Check all fittings and screw connections for tightness.
•It is recommended to remove reCool®and clean the reCool® system for the prevention of corrosion should
the unit go long periods between uses.
Warranty and Liability
REGO-FIX®will not honor the warranty or accept any liability for damages caused to either persons or machinery
which can be attributed to one or several of the following causes:
•Inappropriate use of the reCool®.
•Inappropriate repairs on the system, done by non-instructed personnel.
•Inappropriate transport, storage, assembly, commissioning, operation and maintenance of the system.
•Operating of the system in spite of broken safety equipment or insufficiently mounted or not functional
safety and protective equipment.
•No attention to recommendations stated in the operating instructions concerning safety, transport, storage,
assembly, commissioning, maintenance and setup of the system.
•Constructive change of the system without permission.
•Lack of control of the system parts, which may be subject to wear.
•Inappropriate repairs and use of spare parts from other suppliers.
•Catastrophic impacts, e.g. by external matters or force major risks.

Overview
Use
reCool®is used exclusively for clamping tools with ER Collets (DIN 6499 / ISO 15488).
Only original collets, sealing and cooling disks REGO-FIX®are to be used.
Technical Data
Coolant pressure: The reCool®static RCS/ERMX is designed for up to 150 bar / 2175 PSI and is available
with the following options:
- as a complete set with hose and fittings for up to 100 bar / 1450 PSI
- RCS/ERMX separately
- high-pressure hose (including screw coupling) up to 150 bar / 2175 PSI (see chapter 9)
Coolant: Oil and emulsion coolant (filtered with a 20 µm filter)

For best cooling do not exploit the clamping range of the collet. I.E
. clamp a Ø 6mm tool
shank in Ø 6.0 – 5.0 mm collet.
Do not use reCool®with metallic sealed ER-
DM Collets, because the coolant cannot enter
the tool.

Assembly
Preparing the manifold for static tools
1. Remove the old coolant pipe or fitting.
2. Screw in the supplied fitting (1/8": BSP straight or 90° angle).
If the coolant pressure is higher than 100 bar, screw in the high-pressure
braided steel hose RHS-HP (≤150 bar) with the fixed thread side.
For all other fittings and hoses, see optional accessories in chapter 9.
3. It is necessary to seal the toolholder, so that the coolant cannot
emerge through the hole in the rear.
Through holes in the toolholder must be closed!

5
Preparation of reCool®
1. Insert the small diameter of the disk into the center of the coolant nut and
apply even pressure until the disk is properly seated into the nut.
Sealing Disk DS Coolant Flush Disk KS
Marking Marking
If reCool®is used without a sealing or flush disc
the unit will not provide the desired
cooling.
2. Screw in the supplied fitting (1/8” straight or 90° elbow).
If the coolant pressure is higher than 100 bar, do not fit the high-pressure hose
fitting RHS-HP (≤150 bar) yet (see 3.3).
3. Insert groove of the collet into eccentric ring of reCool®at the mark on the
bottom of the nut. Push collet in the direction of the arrow until it clicks in.

Improper assembly can
permanently damage the concentricity of the collet and may
result in the damage to the clamping nut.
Only mount reCool®with correctly inserted collets! Never place the collet into the holder
without first assembling into the reCool®nut.
reCool®is not to be used with a sealed collet!
Inserting the tool and mounting on the toolholder
1. Insert cutting tool into reCool®then assemble on to the driven head.
Insert tool from the front, otherwise the O-ring can be damaged in the sealing disc.
2. Tighten with wrench Type E MX or torque wrench with wrench head.
We recommend reCool®to use with a torque wrench to tighten properly
(Recommended tightening torques see chapter 5).
Insert tool to the full length of the collet for best results if possible. However never insert
the tool less than 2/3 of the collet bore length.

7
The maximum torque shall not be more than 25% above the recommended tightening
torque.
3. Push the supplied hose into the fitting of the reCool®to the stop and cut to
the shortest possible length.
With a coolant pressure higher than 100 bar, screw in the high-pressure hose
fitting RHS-HP (≤150 bar) with the loose fitting side.
4. Attach supplied coolant pipe with protector (Spring) onto the tube and cut
about 15mm shorter than the tube.
5. Push in pipe with protector in the tool holder until it stops.
Make sure the hose is firmly pressed in to each fitting.
Failure to do so could allow the
hose to come out and no coolant can flow to the tool.
Disassembly and tool change
1. Remove the pipe on one side of the reCool®assembly (press the plate on
the fitting and pull out the hose).

8
2. With wrench Type E MX or torque wrench with wrench head Type A-E MX
and unscrew by hand.
3. Remove and replace tool with the same diameter, or replace the collet and
sealing disc with new diameter and insert the new tool
4. Reassemble reCool®as described in chapter 3.3.

DANGER
Follow all machine and company safety guidelines when operating the machine.
Long term interruption of use
It is recommended to remove the reCool®System during longer interruptions, to clean
with a degreasing detergent and to coat with a rust protection spray.
Maintenance
The reCool®static coolant supply system does not have any rotating parts, thus limiting the maintenance to
cleaning.
