The scale handpiece, ult asonic t ansduce (stack), and tip a e wate cooled devices and must always have adequate
wate flow to function p ope ly. The amount of wate delive ed to the handpiece must be egulated acco ding to the
powe level. If the powe level is inc eased, the amount of wate must also be inc eased. Not having enough wate flow
th ough the scaling handpiece may pe manently damage the handpiece, will cause the handpiece to get hot, deg ade
t ansduce life and void the wa anty. Fo mo e info mation, please tu n to the Scaler Operating Instructions page.
When active, ult asonic tips vib ate at ove a million cycles pe minute, if it touches soft tissue o skin it will cause bu ns
due the f iction of the vib ation. The tip is not no mally hot but the ult asonic vib ation will bu n you if you touch it, this is
due to the f iction between the skin and the vib ating tip. This is no mal fo all ult asonic scale s. Neve let the scaling
tip touch soft tissue o skin, Engle Enginee ing Co po ation is not esponsible fo any damage caused by imp ope use
of this device and / o its accesso ies.
When using a wate bottle, it must be kept pumped to at least 30 PSI. The p essu e elease valve will slightly move out
showing the yellow inte io when p essu e builds up. As wate is used the p essu e will dec ease and the bottle must
be pumped to keep adequate p essu e.
Neve twist o bend you ult asonic stack. Be ca eful not to twist o bend the stack when inse ting o emoving it f om
the handpiece. Pull the stack st aight out to emove it. Always make su e the stack is p ope ly aligned when inse ted
into the handpiece. The e is a white dot in the handpiece and a hole in the stack, they must be aligned du ing inse tion.
Bending the stack o inse ting it inco ectly into the handpiece may i epa ably damage the stack and deg ade it’s
ability to vib ate. Imp ope inse tion of the stack may also damage the handpiece as well as cause it to get hot.
Damage caused by bending o fo cing the stack into the handpiece is not cove ed by the wa anty. A stack emoval
tool is available f om Engle Enginee ing Co po ation, it is pa t numbe 47903.
Do not alte the scaling tip. The tip is shaped to delive the optimum vib ating powe level and keep its optimum
f equency. Defo ming the tip in any way will cause the handpiece to get hot, deg ade vib ation powe and void the
wa anty.
D opping the handpiece with the stack and tip may alte o damage you tip and stack causing the handpiece to get
hot, deg ade powe / vib ation and void you wa anty.
Remove the tip and nosecone f om the stack and clean / disinfect afte eve y use. Stacks, tips, p ophy angles, ubbe
cups, st aight handpieces, bu s, and wate filte s, a e no mal wea and tea items. In o de to achieve optimum
pe fo mance they should be eplaced egula ly.
The ult asonic stack no mally last six months to a yea . To maintain optimum pe fo mance, eplace eve y six months to
a yea o as needed. Do not leave the ult asonic stack inside the ult asonic handpiece fo long pe iods of time. The
O- ings may d y out and make it difficult to emove the stack.

I TRODUCTIO
Thank you fo pu chasing the Engle Vet II Ult asonic Scale .
The design of the Vet II scale ci cuit y uses integ ated compute technology along with ou Time Remote
Feedback Ci cuit y. This combination p oduces a powe ful and potent tool against pe iodontal disease. A
einfo ced solid aluminum chassis su ounds the ci cuit boa d, p oviding a ve y du able and eliable unit.
The dental scale utilizes an ult asonic p inciple of ope ation. The ci cuit y conve ts o dina y line voltage to an
ope ating f equency of app oximately 25,000 Hz. This f equency is then amplified and delive ed to the scaling
tip. As a esult, the tip vib ates at this ult asonic f equency with an amplitude of 0.001 to 0.004 in. (25.4 um to
102 um).
In designing ou unique Engle tips, wate flows inte nally th ough the tip as it vib ates. As the bubbles in the
lavage a e bacte icidal, the ene gy eleased collapses and dest oys the bacte ial cell walls. The wate flowing
inte nally th ough the tip, effectively cools the a ea and assists in emoving any deb is f om the ope ative site.
This device is equipped with a digital eadout that p ovides an indication of the powe that the unit is set at.

ULTRASO IC SCALER HA DPIECE
Note: Wate lines we e pu ged p io to shipping. When activating the Vet II fo the fi st time, please
follow these inst uctions.
To begin:
WITH O STACK / I SERT I THE HA DPIECE, otate the powe cont ol knob to the ight, the
knob will click “on” and the g een LED will illuminate. This indicates that the scale has powe and is
eady to be used. Adjust the POWER CO TROL knob to the MI IMUM powe setting, (counte -
clockwise otation), set the WATER CO TROL to its MAXIMUM setting by otating it
counte clockwise, (knob will otate up to 3 and a half tu ns fo maximum wate flow).
Hold the handpiece ove a cuspido o sink and dep ess the footswitch until wate comes out of the
handpiece, this should only take a few seconds.. This step is done to insu e p ope ope ation of the
delayed cavitation featu e by emoving ai that may be t apped in the wate lines.
Place insert into handpiece:
To place an inse t into the handpiece, the e is no alignment necessa y; the ope ato need only d op
the inse t st aight into the handpiece. When the plastic f om the inse t meets the im of the
handpiece, push the two togethe to c eate a good seal. To change inse ts, the ope ato need only
pull the inse t st aight out of the handpiece and exchange it fo a diffe ent one. Pe iodically lub icate
O- ing on the inse t with pet oleum jelly o equivalent.
Set the powe cont ol and the wate cont ol to a level whe e you develop a fine mist at the tip.
OTE: Inserts sent from our facility are not sterilized.
WAR I G: The ultrasonic scaler is not designed to run without water. Running the handpiece
without water for 30 seconds or longer will damage the handpiece and void the warranty.
The 25K scale inse t is a one-piece design. This means the tip is not emovable f om the inse t.
The e is no nosecone to eplace.
Inserts sent from our facility are not sterilized.

BASIC SCALI G PROCEDURES
1. Befo e placing tip into patient’s mouth, activate the scale handpiece ove a sink by dep essing the
footswitch. A fine mist, with the tempe atu e between cool to lukewa m to the touch is
ecommended. This should be accomplished with minimal powe and p ope wate flow.
2. It is ecommended that when a tip is placed into a patient’s mouth, the lips, cheek and tongue
be et acted to p event contact.
3. Place the tip into the patient’s mouth and dep ess the footswitch to activate the scale .
4. B ing the tip to the tooth and gently move it ove the su face of the tooth with an e asing motion.
5. A saliva ejecto o HVE is ecommended.
IMPORTA T: Do not leave the vibrating tip in one place as it can cause serious damage to the tooth or
surrounding tissues. Engler Engineering Corporation will not be liable for damage due to improper
use of this device.
ote: We have designed the this device with a featu e called Delayed Cavitation. This function pu ges the tip
of wate afte eleasing the footswitch to p event bacte ia f om ente ing the tip.
IMPORTA T: Excessive p essu e on the tip is not necessa y to emove calculus o ta ta . Enamel on the teeth
may be damaged o emoved if excessive p essu e is used. The enamel may be damaged if the scaling tip is
left to est in one spot fo even a few seconds. Using the tip, as a p y to emove calculus o ta ta is st ongly
discou aged as it can damage the teeth and incidentally change the shape of the tip, alte ing it's pe fo mance.
The no mal powe setting fo most p ocedu es should be nea mid- ange. Since eve y ope ato has a diffe ent
technique, the powe may be adjusted to satisfy specific equi ements. Ult asonic scaling p ocedu es a e not
intended fo soft tissue.
CAUTIO : Contact with Soft Tissue Will Cause Burns. Engler Engineering Corporation will not be liable
for damage or injury due to improper use of this device.
DE TAL PROCEDURES SHOULD BE PERFORMED O LY BY QUALIFIED PERSO EL.
THIS EQUIPME T IS FOR PROFESSIO AL USE O LY.
