Storage
In filled condition the extinguisher must be stored in an upright
position. The environment should be dry, cool and dust-free.
Avoid direct sunlight; in the long run, ultraviolet light harms
plastic, rubber and textiles. If filled with regular extinguishing
agent, do not expose the device to temperatures near freezing
point or below. Frozen extinguishing media causes irreparable
damage! Use frost proof additives for cold conditions.
Extinguishing agent
As a specialized extinguisher
against burning magnesium and
other metals, the "HiPRESS Cold
Metal" must be filled solely with
"HNE-Cold Metal" in undiluted
concentration. For proper effect,
this special extinguishing media
necessarily requires HNE-high
pressure technology and is
supplied by HNE to registered
customers only.
Regular range of temperature: -20 to +60° C
Do not store the filled extinguisher in horizontal position.
DANGER:
Use "HNE Cold Metal" in undiluted concentration only!
Any addition of other fluids, especially water will result
in explosive reactions upon contact with burning metal.

Before you start:
Avoid spilling of extinguishing agent. Flush affected
surfaces and components with water.
Empty the container completely before filling.
Dispose of chemicals with ecological responsibility.
Do not use any leftover extinguishing again.
Never overfill the container.
The threads of container and lid have to be free of dirt
and debris. Clean if necessary and lubricate with silicon
grease.
Always wear goggles, gloves and apron when dealing
with extinguishing agent. The chemicals can cause skin
irritation or allergies.
After contact with eyes or mouth, immediately flush out
with plenty of clean water.
Also observe the safety instructions in the data sheet of
the extinguishing agent manufacturer.
Extinguishing agents are polluting and hazardous to
health. They must not seep into soil or sewer system.
Use a suitable container to dispose of it in an
environmentally friendly way.
The extinguisher achieves optimal performance only when
accurately filled. Prepare things thoroughly and perform all steps
with necessary care. We recommend a clean and steady work
area with water supply.
Filling
We recommend to mark the extinguisher after filling as
ready for use. For example, a paper seal can state the
date and type of extinguishing agent.
HiPRESS 50 - COLD METAL

OPEN
Relieve the system always completely from residual
pressure before opening the container lid. Even after
complete discharge of the extinguisher, new pressure
can occur due rising temperature.
Venting the system:
2. Turn the upper knob into open
position ( ) for venting.
1. Make sure that the valve of the
compressed air cylinder is closed.
3. Press and hold the trigger of the jet
gun until no more hissing is heard.
4. Place the device on a level surface
and remove the pressure bottle (see
next page). Then unscrew the lid.
Closing the lid:
A thin layer of silicon grease on thread and
sealing surface increases lifetime and
facilitates opening. Screw the lid tightly and
turn the vent valve into closed position ( ).
Tightening by hand is sufficient. Do not use tools.

The container requires a total filling of exactly 50.0 liters of
"HNE-Cold Metal". The specialized extinguishing media comes
ready for use. Never dilute or mix it with any other fluids.

Replacing the pressure bottle
Do not use tools to tighten the hand screw at the air
cylinder connection.
Partially emptied air cylinders must be recharged or
replaced before the next use of the extinguisher.
The threads of air cylinder and regulator must be free of
dirt and debris. Clean if necessary, but do not lubricate.
Check the condition of the O-ring at the pressure
regulator. Replace it in case of cracks or loss.
Do not open the cylinder valve before the next use.
Never overfill an air cylinder. Maximum pressure: 300 bar.
Use approved pressure bottles of same size only.
If the air cylinder is opened by mistake, close it again and
discharge the pressure by opening the vent valve of the
lid. The remaining capacity of the air cylinder is still
sufficient. Refill or replace the bottle in case of recurrence.
If necessary, clean the threads of pressure tank and air cylinder
connection with compressed air or a small brush. Do not
lubricate. Check the condition of the O-ring before screwing the
regulator to the compressed air cylinder.
Pressurized vessels represent significant hazard for user and
vicinity in case of negligence or mishandling. Always treat filled
air cylinders and charged extinguishers with due diligence.

To avoid accidental opening and to indicate readiness,
we recommend marking the hand wheels of filled
cylinders with paper seal.
Replacing the pressure bottle
A compressed air cylinder with 6.8 Liters volume serves as
propellant. It needs to be filled with a suitable compressor;
the maximum pressure of 300 bar must not be exceeded.
Remove the empty cylinder.

Wheel brakes
Lock the brakes always on both wheels to prevent the
device from turning around its own axis.
The push handle is adjustable by 180°
in five steps and can be folded down
completely to save space. For
adjustment pull both latch pins (1)
outward simultaneously (2) and move
the handle into desired position until
both pins snap into place again.

For safe use on slopes, both
front wheels are lockable. To
apply the brake, press the
protruding metal flap with the
foot firmly against the roller. To
unlock, lift the flap with the shoe
tip from underneath.

jet gun. Range and flow rate are variable by stepless actuation.
This increases efficiency and duration significantly when fighting
small fires. A foldable safety catch prevents accidental actuation

The double-tube jet gun is ideal
for smoke suppression and treatment
of smoldering embers. When set to
spray mode, the total duration of the
extinguisher is increased significantly due
reduced flow rate. Atomized by a special
nozzle, extinguishing media is blasted with
area effect into a far reaching cloud of foam.
All basic functions of this jet gun are identical
to the standard version (see previous page).
Setting the jet mode:
Turn the two jet tubes by 180 degrees until the pivot sensibly
locks into place in the new position. The tube in the upper
position is active.

Service and maintenance
HNE-extinguishers have to be inspected regularly for function
and readiness by qualified personnel, but at least every 12
months according to the following inspection scope:
•General condition and cleanliness
•Legibility, completeness and correctness of the labelling
•Fittings, hoses and attachment parts
•Damage to protective coating and possible corrosion
•Plastic parts of jet gun and backpack for cracks or deformation
•Smooth operation of all moving parts and switches
•Age of Filling: change at the latest after 12 months
•Condition of internal coating: check with inspection lamp
•Filling state of the compressed air cylinder: 300 bar
•Condition of seal rings in filler neck and at pressure reducer
•Tightness of tension belts (air cylinder and backpack)
Check and clean the extinguisher thoroughly after every
use, even if it has not been applied.
Check the fully operational condition. If necessary,
restore it by repair within the limits of your legitimation.
All spare parts must be approved for use with the device.
To gain full performance, extinguishing media in the
container must not be older than 12 months. Do not use
any leftover extinguishing agent again.
After maintenance or repair, the extinguisher should be
labeled with filling date and content.
NOTE: As a highly safety-relevant element, the pressure
reducer is absolutely maintenance-free. Any work or repair
at it is solely reserved for HNE. Unauthorized action leads
to the complete loss of warranty.

Safety

Legal inspections
Extinguishers are subject of periodic
checks for function and safety. Legally
prescribed inspections are country
specific and vary. The owner is
responsible for compliance with
prescribed intervals. Therefore, the
container is labeled with badges for the
date of manufacturing and the maturity
of the next inspection. The punched-out
areas mark the exact period.
Compressed air cylinders too must be approved and
tested regularly. Please keep yourself informed about the
regulations in your country.
The badge for the next inspection date must be updated
after every inspection.
Pressure safety
The entire pressure system is extremely
robust and designed to withstand high
overload. In addition, there is an
automatic pressure relief valve for safe
discharge of potential overloads. It is
located at the protected position
between container and backpack and
requires no maintenance.
The safety valve is precisely adjusted and sealed.
Do not adjust or work at it with tools.
If the safety valve is responding, only the effect, not
the cause of excess pressure is eliminated. The
device must be checked thoroughly before next use.
