1. Note that there are two versions of the ErgoGrip with different lenses and light pattern and
intensity: “ErgoGrip LED” and “ErgoGrip FocusLED”.
2. Check that lens in the ErgoGrip is clear and clean. Clean or replace if necessary.
3. If you have an additional scaler handpiece (or polisher tubing), try replacing the scaler
handpiece (or polisher tubing).
4. If the problem still remains –contact your dealer for support and indicate Error Code “E-S03
No light in scaler handpiece“ or “E-P03 No light in polisher handpiece”
E. No tip vibration
1. Check that the tip is firmly tightened. Preferably use a torque wrench and tighten clockwise
until the torque wrench slides. (The torque wrench prevents the tip from being overtightened.)
2. Check that the green light below the keys on the control panel is lit. If it is not lit, please see
Section A on page 4.
3. Check that the device has been turned on by pressing the S-key and that the blue light next to
the S-key is lit.
4. Check that the Working Mode has been selected by pressing one of the Working Mode keys
and that one of the yellow lights on the control panel is lit.
5. If you have an additional handpiece, try replacing the handpiece.
6. If you have an additional foot control cable, try replacing the foot control cable.
7. If you have an additional foot control, try replacing the foot control.
8. If the problem still remains –contact your dealer for support and indicate Error Code “E-S01
No vibration” or “E-S02 Low power / vibration”
F. Weak tip vibration
1. Check that the tip is firmly tightened. Preferably use a torque wrench and tighten clockwise
until the torque wrench slides. (The torque wrench prevents the tip from being overtightened.)
2. Check that the tip is not worn out. Use a tip check card to evaluate wearing or try an unused
tip. Use original LM-Instruments tips for reliable performance.
3. If you have an additional handpiece, try replacing the handpiece.
4. If the problem still remains –contact your dealer for support and indicate Error Code E-S02

G. Insufficient or no water flow (Scaler)
1. Check that dry mode is not activated i.e. that the blue light next to the crossed-out water drop
is not lit. If it is lit, press the S-key.
2. Adjust the water control ring on the handpiece to fully open (dots aligned).
3. Check that the medicament/water bottle is properly connected i.e. the cap is tightened and
pushed in all the way onto the connector. Check that the o-rings on cap and connector are in
good condition. Replace o-rings if worn. O-rings can be lubricated with a glycerine based
lubricant.
4. Try with another tip.
5. Use the LM-ProPower Fixer to check that the water hose inside the handpiece has not stuck
in the autoclave. Insert the Fixer carefully into the handpiece from the hose connector side.
(To avoid the hose getting stuck, the water adjustment on the handpiece should be set to fully
open before sterilization in autoclave.)
6. If the problem still remains –contact your dealer for support and indicate Error Code E-S04
H. Tip does not fit smoothly onto the handpiece
1. Clean handpiece threads with compressed air and try with a new tip
2. If the problem still remains, the threads of the handpiece may be damaged and the handpiece
needs to be replaced. Contact your dealer and indicate Error Code E-S06.
I. Handpiece is overheated during use
1. Check that the fluid flow is sufficient (at least 20 ml/min)
2. If the problem still remains, replace the handpiece and contact your dealer
J. Insufficient or no water flow (Polisher)
1. Check that Air Blow mode is not activated i.e. that the blue light next to the crossed-out water
drop is not lit. If it is lit, press the P-key.
2. Adjust water control on powder container cap to fully open.
3. Check that the medicament/water bottle is properly connected i.e. the cap is tightened and
pushed in all the way onto the connector. Check that the o-rings on cap and connector are in
good condition. Replace o-rings if worn. O-rings can be lubricated with a glycerine based
lubricant.
4. Gently check that the nozzle is fully tightened
5. If you have an additional nozzle, replace the nozzle.
6. If the problem still remains –contact your dealer for support and indicate Error Code E-P04
K. Insufficient or no powder flow
1. Check that there is powder in the powder container and that the o-ring in the cap is in correct
position.
2. If you have an additional nozzle, replace the nozzle. A clogged nozzle may be cleaned in an
ultrasonic bath or in citric acid (or vinegar).
3. Unscrew and remove the powder container, nozzle and ErgoGrip and blow with compressed
air into the handpiece.
4. If the problem still remains –contact your dealer for support and indicate Error Code E-P01.
L. Water drips from the bottom of the device onto the table
1. The ProPower device has a built-in water trap that removes humidity from the pressurized air
coming from the compressor in the compressor room of your clinic. The water trap condenses
the humidity in the pressurized air into water which is then released underneath the device.
Normally there is no water at all or a very small amount (a few drops). If the amount of water
is significant, the compressor of your clinic may need service. Please contact the
manufacturer or dealer of your compressor.
