5.2.1 EnSet© Plus Pulse Mode
No. Description
In this mode you will always have the same number of impacts/minute no
matter how much pressure is applied to the foot pedal. The machine will
always run at the same speed. As you depress the foot pedal the power in
each impact will increase and conversely, as you ease up on the foot pedal
the power will decrease.
(A)
Press « Mode » button (12) to select the EnSet© Plus mode.
By pressing on the « Mode » button (12) you can toggle back and forth
between Original and Plus modes.
In the pulse mode both windows will display « 0 » (zero) when you are not
actively setting them. During operation the bottom window (13) will display the
number of impacts that you set and the top window (8) will display air
pressure. The top window air pressure will fluctuate according to how hard
you are stepping on the foot pedal. The more pressure on the foot pedal, the
more air pressure and power with each impact. The less pressure the less
power with each impact.
(B)
Use the « + » and « - » buttons (9) to the right of the top pressure window to
set the maximum air pressure desired.
The minimum air pressure is already programmed into the system. This
feature is useful because it can act as a limiter. Once set, it will only let the
machine increase the impact power up to the set air pressure. If you would
like it to have the full range of impact set this air pressure to 100 psi (7 bar).
The air pressure may be adjusted at any time using the pressure (+) and (-)
buttons.
(C)
Use the « + » and « - » buttons (14) to the right of the Pulse window to set the
desired number of impacts/minute.
Page 21
EnSet© Plus / Original / Compact
Version 03 - 15.10.2018
21/40
The window displays a number between 1- 40 corresponding to the speed.
Multiply the number by 60 to calculate the actual number of impacts/minute.
For example :
1 * 60 = 60 impacts/minute
4 * 60 = 240 impacts/minute
10 * 60 = 600 impacts/minute
Maximum number of impacts/minute is 2 400 (40 * 60)
The number displayed in the bottom window may go above 40 on some units.
However, the speed increases only to a maximum of 40 (2 400 impacts/
minute). The machine does not go faster even if a number over 40 is selected.

5.2.2 EnSet© Plus Pressure Mode
No. Description
In this mode you set the air pressure for the input and the foot pedal controls
the number of impacts per minute (speed) of the tool.
(A)
Press « Mode » button (12) to select the EnSet© Plus mode.
By pressing on the « Mode » button (12) you can toggle back and forth
between Original and Plus modes.
In the pressure mode the air pressure is displayed in the top « Pressure »
window. The bottom window displays « 0 » (zero) until you engage the foot
pedal. Once you step on the foot pedal you will see a variable number of
pulses in the bottom window.
(B)
Use the « + » and « - » buttons (9) to the right of the top pressure window to
adjust the working air pressure up or down between 35 - 100 psi (2.41 7 bar).
In this mode the number of impacts per minute will be displayed in the bottom
window as you step on the foot pedal. The harder you step on the foot pedal
the more impacts will occur (faster speed). The display (13) in the bottom
window will continually adjust based on how much pressure is being applied
to the foot pedal.
The number of impacts displayed in the bottom « Pulse » window (13) must be
multiplied by 60 to get the actual number of impacts/minute. For example :
1 * 60 = 60 impacts/minute
4 * 60 = 240 impacts/minute
10 * 60 = 600 impacts/minute
Maximum number of impacts/minute is 2 400 (40 * 60)

5.3 Tuning the EnSet© Units for Optimum Air Pressure
Through Full Range of Speeds
No. Description
(A)
Turn air pressure on machine to 32 psi (2.20 bar).
(B)
On EnSet© Original or Compact unit:
Turn knurled knob (9) to increase or decrease pressure.
(C)
On EnSet© Plus unit:
Make sure the « Pressure Mode » is selected when tuning the EnSet© Plus.
Press « + » or « - » button (9) to right of Pressure window to increase or
decrease air pressure.
(D)
Hold the handpiece in the hand.
(E)
Step on foot pedal and press until pedal is completely engaged (all the way to
floor).
(F)
Continue to hold foot pedal down.
(G)
While holding foot pedal slowly increase pressure up to 65 psi (4.48 bar).
Watch the air pressure on the gauge (8) for EnSet© Compact and Original or
in the Pressure window (8) for EnSet© Plus.
Notice where the handpiece has crisp powerful taps and where the power
starts to fall off. There is a pressure around 40-50 psi where there is good
power and crisp tapping at the fastest speed (foot pedal to floor). Once the air
pressure gets too high the power of the impacts starts to decrease at the
highest speed.
Dial the air pressure back down to the range where you have the best power
through the high speed range.
(H)
This will give you an optimum air pressure to have excellent power through
the entire speed range of the tool.
If you need increased power especially on the slower speed then you may dial
the air pressure up to 100 psi (7 bar). This will give you very powerful impacts
on the slow speed needed for setting gold, punch dot backgrounds or for
sculpting/heavy work especially when paired with the heaviest striker head
(12 grams).

6 HANDPIECE SETTINGS
6.1 Description
In order to obtain the highest performance of your impact handpiece,
make sure to align the striker head on the shaft with the setscrew
tightened in the indented area. This will ensure that the tool will move
freely so that the striker shaft impacts the graver collet. The machine
operates most efficiently with the striker head in this position on the
shaft.

To change the striker head (15), unscrew the handpiece in the middle to gain
access to the striker head shaft (17).
(B)
Select desired striker head according to desired power.
There are 3 striker heads that come with the handpiece unit :
- Small Steel For light shading and fine work
- Medium Brass For overall cutting work
- Large Tungsten For heavy work
(C)
Remove striker head currently on shaft by loosening the setscrew (16) and
sliding the striker head (15) off the end.
(D)
Slide desired striker head on the shaft.
Note that shaft has indented area that will position striker head correctly. Look
through the opposite hole to the setscrew to view indentation on shaft.
Position striker head so setscrew will tighten in indentation on shaft. Tighten
setscrew to affix striker head. Striker head should not be all the way to the
bottom of shaft so it is sitting on handpiece handle, nor should it be all the way
to the top of shaft or it will impact the inside of cylinder area and not efficiently
impact the back of the collet/graver.
(E)
Reassemble handpiece by screwing front and back of handpiece together.
Sometimes during heavy hitting the striker head may become loose. You will
hear a difference in the sound of impact when this happens. Unscrew the
handpiece and re-tighten setscrew to secure striker head.

6.3 Stroke Length Adjustment
The EnSet© tool allows the user to choose the stroke length of each impact by
adjusting where the striker head impacts the collet. It can barely tap the back of
the collet for light, fine work or it can impact the collet fully for much more power
in each stroke.
6.4 Basic Stroke Length Adjustment
No. Description
(A)
Install graver (18) into collet (20), tighten collet setscrew (19).
(B)
Insert collet with graver into handpiece barrel (22). Rotate collet until detent
ball « clicks » into position. You will feel that there is resistance to rotating the
collet once it is set in position.
To remove collet: twist collet/graver until detent ball releases from lock
position and remove from handpiece sleeve.
(C)
While holding collet/graver - step on foot pedal to actuate machine.
(D)
While handpiece is striking, turn knurled ring (21) to the left until you can hear
that the striker head is not directly impacting the back of the collet. You will
hear and feel that the striker head does not have a crisp hit on the collet as
you turn the knurled ring to the left.
(E)
Keep machine on so that the striker head is active.
(F)
While the machine is working, slowly turn knurled ring (21) to the right. Listen
to the sound and pay attention to the feel of the tool in your hand. Keep
turning the ring until you hear crisp taps on the back of the collet. This is
where the striker head starts to come into direct contact with the back of the
collet.
For a longer stroke with more power: turn ring more to right.
For a shorter stroke with less power: turn ring to left.
If you turn the ring too much to the left so the collet is not impacted, then the
tool will not function efficiently.
You can re-adjust stroke length at any time depending on the power or
character of the cut you wish to make:
- Shorter strokes = less pronounced progress marks, less power/impact;
- Longer strokes = more pronounced progress marks, more power/impact.

6.5 Advanced Stroke Length Adjustment
Another way to adjust the stoke length is to adjust it while actively engraving. Use
a practice piece for this method until you fully understand the adjustments so as
to not ruin your work.
No. Description
(A)
Install graver (18) into collet (20), tighten collet setscrew (19).
(B)
Insert collet with graver into handpiece barrel (22). Rotate collet until detent
ball « clicks » into position. You will feel that there is resistance to rotating the
collet once it is set in position.
To remove collet: twist collet/graver until detent ball releases from lock
position and remove from handpiece sleeve.
(C)
While holding collet against front of tool place graver down onto practice plate
just like you would engrave.
(D)
Step on foot pedal and begin to engrave.
(E)
While continuing to engrave, slowly turn the knurled ring (21) to right or left to
adjust stroke length longer or shorter. Use your thumb and index finger to
adjust the ring.
For a longer stroke with more power: turn ring to right.
For a shorter stroke with less power: turn ring to left.
If you turn the ring too much to the left so the collet is not impacted, then the
tool will not function efficiently.
The longer the stroke, the more percussive the collet/graver. It will travel much
farther and will need more pressure to hold it into the handpiece.
(F)
Choose a moderate speed to engrave while adjusting. If the speed is too slow
it is difficult to feel the stroke length.
(G)
Identify the stroke length that suits your project/engraving.
You can re-adjust stroke length at any time depending on the power or
character of the cut you wish to make:
- Shorter strokes = less pronounced progress marks, less power/impact;
- Longer strokes = more pronounced progress marks, more power/impact.

7 MAINTENANCE
EnSet© is a strong and reliable electro-pneumatic system. However, some
elements have a limited life and need to be replaced from time to time. Below
please find a detailed list of actions in order to preserve your machine’s life.
7.1 Drain Bowl – Particle Filter
EnSet© incorporates an auto-purging drain bowl on its rear panel (2). Auto
purging is intended to occur each time air line is loaded with air. In any case it is
important to take constant care of the drain bowl and purge it manually if
necessary in order to avoid moisture getting into internal components of the
machine (manual air line filter for EnSet© Compact).
The particle filter needs to be kept clean. It is recommended to replace the particle
filter once per year in order to make sure no dirt reaches the internal components.
If the filter becomes visually tarnished or dirty, replace your filter as soon as
possible to prevent possible damage.
Air Supply : Some silent air compressors work on basis of an oil cooled motor. If
this is the case with your compressor, please remember your compressor can
send oil particles into EnSet© internal components through the air line. An oil
coalescing filter is suggested in order to avoid oil contamination. Oil needs to be
fully replaced periodically in oil lubricated compressors.
External contamination caused by oil, water, moisture and/or dirt cause
damage to the machine.
Damage from failing to properly clean the machine or ensuring a clean
air supply is excluded from manufacturer’s warranty or responsibility.

7.2 Lubrication
EnSet© system, including control unit, foot pedal and handpiece do not need
lubrication for its operation. Do not use oil or other lubrication in them.
Lubricate the EnSet© collet O-rings (23) periodically for easier insertion into the
front of the handpiece.

7.3 Handpiece
EnSet© handpiece incorporates a cylinder/ piston system (24). In order to keep
maximum power, replacing this mechanism each 18-24 months is recommended,
depending on amount of activity.
Lubricate the handpiece once a year with vaseline.
No. Action
(A)
Unscrew the handpiece (24) in the middle to access the striker head shaft.
(B)
Remove striker head (15) on shaft by loosening the setscrew (16).
(C)
Remove the handpiece cap (26) to the cylinder / piston system (25).
(D)

8 WARRANTY
EnSet© Plus, EnSet© Original and EnSet© Compact including the control unit,
power supply, foot pedal and handpiece are covered for a one (1) year period
under warranty. Warranty covers components, parts and labor.
This warranty excludes misuse, external contamination from the air supply (oil,
water, dirt particles), an eventual electrical surge, impacts or accidental situations
occasioned by thirds.
If you experience technical problems or questions, please contact Usines
Métallurgiques de Vallorbe SA or one of our authorized representatives in your
area.
These products are designed for reliable operation using most sources
of compressed air. However, some air-supplies contain excessive
water, oil, dirt, rust, or other contaminants. The built-in filter of the
engraving system is a final filter to protect against normal dirt and
water. If the compressed air has excessive contaminants, install the
necessary filter(s) and water trap(s) ahead of the engraving system.
Oil contamination can be gradual and subtle. If an oil residue (usually
yellow or brown, sticky or liquid) becomes present in the filter bowl of
the engraving system, or in the handpiece / throttle hose, the
compressed air most likely contains oil or contaminants. Older oil
lubricated and "silent" compressors that use internal oil are more likely
to cause oil contamination. If this occurs, install a coalescing oil filter.
Damage caused by contaminated compressed air is not covered by
the warranty.
