1. Introduction
We are pleased with your decision to purchase
the Waxlectric I or Waxlectric II. This device
sets a new standard with regard to functionality,
performance, and safety.
Please read the following operating
instructions carefully and observe the
information they contain in order to
ensure a long and trouble-free service
life.
An external transformer supplies the wax kni-•
fe with 12 V power. As a user, this increases
your safety during your daily work with the
Waxlectric.
Using a programme key you can save up to•
3 temperatures for each channel and quickly
call them up again
The defining feature of the• Waxlectric is its
heater which is located directly in the model-
ling tips. This allows the tips to react more
rapidly to temperature changes. The knife’s
thermal dynamics are markedly improved by
the highly heat conductive special alloy.
The electric wax knife is extremely service•
friendly. The modelling tip surfaces are not
finished and can therefore be easily reground
as required. Should the heater develop a
fault, only the tip need be replaced.
The wax knife (no. 2155-0112, Large
Wax Knife (refer to “Accessories”)
may not be reground or re-sharpened.
2. Application Area
The Waxlectric is an electronically controlled
wax knife, suitable for practically all modelling
and waxing-up applications.
It is available in either a one- or a two-channel
version. The operating temperature can be ad-
justed in 1°C-increments from 50°C to 200°C [in
2°F-increments from 122°F to 392°F]. However,
do not set the temperature too high, as some
waxes are very sensitive to overheating.
2.1 Ambient Conditions in Accor-
dance with DIN EN 61010
The unit may only be operated:
Indoors;•
Up to an altitude of 2,000 m above sea level;•
At an ambient temperature range between 5 -•
40ºC [41 - 104ºF]
At a maximum relative humidity of 80% at•
31ºC [87.8ºF], dropping in a linear manner to
50% relative humidity at 40ºC [104ºF] *);
With mains power where the voltage fluc-•
tuations do not exceed 10% of the nominal
value;
Under over-voltage category II conditions;•
Under contamination level 2 conditions.•
*) Between 5 – 30°C [41 – 86°F], the unit can be operated at a
relative humidity of up to 80%. At temperatures between 31
– 40°C [87.8 – 104°F], the humidity must decrease proporti-
onally in order to ensure operational readiness (e.g., at 35°C
[95°F] = 65% humidity; at 40°C [104°F] = 50% humidity).
The unit may not be operated at temperatures above 40°C
[104°F].

Please note:
Units equipped with a power cord
terminating in a Euro-plug (in accor-
dance with DIN VDE 0620) are factory
pre-set to °C.
Units equipped with a power cord ter-
minating in a 2-contact, US flat plug
(NEMA 1-15P) are factory preset to °F.
5.4 Temperature Adjustment
The modelling tip temperature is set by means
of the two keys on the temperature adjustment.
+key: Increases the temperature
-key: Decreases the temperature.
The most recently set temperature is saved and
will be redisplayed when the unit is again swit-
ched on.
New temperatures are saved approx. 5 se-
conds after they are set.
After a temperature adjustment, the modelling
tip requires several seconds to reach the new
temperature setting.
NEVER attempt to heat the tips more
rapidly by holding them in an open fla-
me. This will destroy the tips.
The employed heating elements have been
specially tailored to the individual modelling tips.
However, manufacturing tolerances
may result in minor differences bet-
ween the set temperature and the ac-
tual temperature at the modelling tip.
5.5 Calling Up Saved Temperatures
The unit can have up to 3 temperatures saved
for each channel.
The selected saved temperature is indicated by
a lighted dot on the temperature display.
Select the desired saved temperature:•

that are not needed.
To do this, press the key -corresponding to
the channel until „O F F“ appears in the display.
To switch a channel that has been switched off
back on, press the key +until „O F F“ is re-
placed in the display by the temperature setting.
Both the temperature setting and the chan-
nel that has been switched off are saved. This
channel remains switched off when the control
unit is switched on again.
Also a switched-off channel can be sa-
ved as described in chapter 5.6.
5.8 Quick Adjustment of the Final
Temperatures
Using this option, you can set the temperature
of both channels directly to either the maximum
or minimum temperature when the unit is swit-
ched on.
Setting the minimum temperature:
Switch the unit off.•
Press• -key of the left channel and keep it
pressed.
Press the on-off switch and keep it pressed.•
Once the unit of temperature is displayed-
(°C or °F), both channels are set to 50°C
(122°F).
Setting the maximum temperature:
Switch the unit off.•
Press• +key of the left channel and keep it
pressed.
Press the on-off switch and keep it pressed.•
Once the unit of temperature is displayed-
(°C or °F), both channels are set to 200°C
(392°F).
Any channels which are switched off
(refer to Sec. 5.7) remain off and are
not set to the minimum or maximum
temperature.
5.9 Storing the Modelling Tips and
Handpieces
You can safely leave unused modelling tips in
the tip holder (Figure 8).
During breaks, you can safely leave unused
handpieces in the quiver (Figure 9).
NEVER insert the handpieces into the
tip holder (Figure 10). This can dama-
ge both the tip holder as well as the
control unit.
NEVER place the handpiece on a flam-
mable surface or cover it!
Fire hazard!
Tips and Notes
In order to reduce the risk of breaking•
the probes, dip them into the hard
wax block with the rounded back sec-
tion! The wax will melt more quickly
and this allows to pick up a greater
amount of wax (Figure 18).
More rapid and efficient modellation•
(time savings of up to 30%!) can be
achieved by pre-warming the wax in
a Renfert Vario E. Wax can be pro-
cessed more gently and cools more
rapidly. This reduces shrinkage to a
minimum.
Because the tip insert surfaces are•
not finished, they can – starting from
their basic shape – be ground, bent,
or polished to suit your particular re-
quirements.
The handpiece cables can be guided•
through an appropriate retainer (eye,
hook, etc.) to allow the handpieces to
hang down from above the work area
at the ideal height. This “cable / hand-
piece overhead suspension” permits
significantly faster handpiece access
/ changeovers.
By setting the temperature at approx.•
50°C [122°F], you can use the slightly
warmed Waxlectric blade to “shave”
the wax crown edge onto the stump
while the wax is warm.

6. Cleaning / Maintenance
Never rinse the unit off with water!
Do not use steam to clean the unit!
Hot steam penetrating the unit can da-
mage it.
Use a soft, lint-free cloth to wipe the unit down
from time-to-time.
Never use cleansers containing sol-
vents!
Wipe the tips off after use; This will prevent wax
from burning onto the tip and maintain the tip’s
optimal heat conducting properties.
6.1 Changing Tips
Burn hazard!
The modelling tips may be hot. Always
allow the tips to cool before changing
them.
Unscrew the tip (Figure 11).•
Make sure the O-ring is properly seated on•
the new insert (Figure 12).
Insert the new tip making sure it is straight•
and hand-tighten it.
Make sure the new tip IS NOT skewed or
cross-threaded (Figure 1).
Make sure the O-ring is properly sea-
ted (Figure 12), the O-ring provides a
seal against the wax.
Modelling tips which are not being used can
be safely and handily stored in the tip holder
(Figure 8).
6.2 Changing the cork sleeve
Unscrew the tip (Figure 11).•
Pull the cork sleeve off towards the front (Fi-•
gure 13).
Install a new cork sleeve, making sure it is•
straight (Figure 14).
Screw the tip back on (Figure 1).•
6.3 Cleaning the Quiver and Tip
Holder
The tip holder and quiver can be easily remo-
ved for cleaning.
Tip holder:•
Press gently from the side, then flip
upwards and pull off towards the rear (Figure
15 + 16).
Quiver:•
Rotate the quiver downwards and towards
the rear to remove it (Figure 17).
Remount tip holder and quiver in reverse order.
