USING THE LAMP

Prior to starting the lamp

• Damaged mantles must be replaced immedi­ately.

• Make sure that needle, spray nozzle, mixing
chamber, and burner are properly tightened
and connected.

Starting the lamp

• See “Starting: Step by Step.”

After starting the lamp

• When the pressure falls below 1 bar, carefully
add pressure to the tank using the hand
pump (approx. 2.5 bar).

Extinguishing the lamp

• To extinguish the lamp, release the pressure
via the bleeder screw.

• In the case of unpredicted flames develop­ment, open the bleeder screw immediately.

• Finish by turning the handwheel upward.

TROUBLESHOOTING

The pump does not work properly.

Pull out the pump plunger, grease the leather
seal and gently widen the leather seal (replace
it if necessary!). Push the pump plunger back
into the cylinder of the pump by turning the
pump plunger.

The upper part of the lamp catches fire.

Preheat the lamp for at least 90 seconds using
the rapid preheater. When pre-heating with the
use of fuel (preheat cup), use at least two full
cups of fuel.

The incandescent mantle does not burn properly.

When using the rapid preheater, position the
incandescent mantle in a way that it can easily
catch fire via the rapid preheater.

The rapid preheater does not ignite/burn properly.

Ensure that there is neither too much nor too
little pressure in the tank. The manometer
needle should be just below the red line! If ne­cessary, clean the nozzle of the rapid preheater
with the cleaning needle included in the spare
parts set.

The light flickers or gets darker.

Make sure that there is enough pressure and
fuel in the tank. If necessary, rapidly turn the
handwheel 360 degrees to free the spray nozzle

of any particles via the needle.

PREHEATING THE LAMP WITH
DENATURATED ALCOHOL

The Petromax HK500 comes with a preheat cup
in addition to a rapid preheater. Preheating
with denaturated alcohol is more gentle on the
mantle.

Preheating the lamp through the preheat cup

• Sprinkle the new mantle with denaturated
alcohol.

• Fill the preheat cup with denaturated alcohol
using the fuel can.

• Burn the denaturated alcohol in the preheat
cup and wait until the cup has burned to the
point of being empty.

• Again, put denaturated alcohol in the preheat
cup and ignite it.

• Wait until the denaturated alcohol has almost
completely burned out, and then turn the
handwheel (with the nose pointing down).

the date of purchase. This does not apply to nor­mal wear and tear. If you cannot use your HK500

STARTING THE LAMP:
STEP BY STEP

Before using your Petromax lamp,
read the Cautions very carefully.

You must not inhale the smoke emit­ted by the lamp, its parts, and the
mantle!

The lamp must not be used indoors!

STEP 1

• Loosen the knurled nuts.

• Remove the hood and the inner casing.

STEP 2

• Tie the mantle to the burner bead with
a double knot. Do not tie the mantle to
the mixing chamber!

• Trim loose threads as short as possible.

STEP 3

• Install the inner casing and the hood
(for older models of HK500 make sure
that the regulating screw at the mixing
tube is visible).

• Tighten the knurled nuts by hand.

• Make sure that the bleeder screw on the
manometer is properly tightened.

STEP 6

• Unlock the pump by turning the pump
knob.

• Repeatedly push the hand pump’s
plunger until 1.5 bar (red line on the
manometer).

STEP 7A

• Push the lever of the rapid preheater
downward, and immediately ignite the
flowing fuel with a lighter.

STEP 7B

(with new mantle only)

• With a newly installed mantle, close
the lever after approx. 10 seconds. Let
the mantle burn down completely until
dyed grey appears, and make sure that
the mantle has no black bits.

• Finish by pushing the lever downward
and immediately ignite the flowing
fuel.

STEP 8

• Repeatedly push the hand pump’s plun­ger to keep the pressure at 1.5 bar.

• The rapid preheater will now preheat
the carburetor. It must be preheated for
at least 90 seconds. The time needed
depends on the outside temperature.

STEP 9

• After 90 seconds, turn the handwheel
nose down.

• As soon as the lamp lights, close the le­ver of the rapid preheater.

• Bring the lamp to operating pressure
(2.5 bar).
