PROBLEM CAUSE SOLUTION
No Water Flow in
Handpiece
1. Compressor not ON.
2. Water Flow Control not ON (P4-
E).
3. Water/CLS Bottle Empty.
4. Check for a ‘kink’ in the water line.
5. Check if 3 way syringe has Water.
6. Use of tap water, blocking water
valves.
7. Low regulator pressure.
1. Turn compressor ON and check
that ON/ OFF tap is in the ON
position.
2. Turn water control to ON.
3. Fill water/CLS Bottle(s).
4. Check lines and pressure.
5. If yes, lack of water must be in the
valves or the handpiece. The 3 way
syringe is the quickest way to check
for water.
6. Valves will need replacing.
7. Check regulator is set at 70 PSI.
Mineral
Accumulation
1. Use of tap water - mineral or
chemical action blockage will
usually take 3-4 years to occur.
2. Verdigrease (Green Slime) build
up in brass water valves due to
chemical reaction with tap water.
1. Pass a fine wire through the water
intake hole. Pass another fine
wire through the hole in the
handpiece head. Pass the wire as
far as possible each way. ‘Blow out’
the loosened mineral deposits.
2. Replace valves.
Use of Chlorhexidine 1. Most brands of Chlorhex will de-
posit out of solution and block
valves, etc. CLS is designed to
be used in its diluted strength
without depositing.
NOTE: Do not dilute CLS beyond
its label recommendations or it
could result in deposits.
2. Chlorine in tap water will cause a
flocculation and block filters and
valves
1. Contact your local Official Service
Center.
2. Contact your local Official Service
Center. Use only distilled water
Handpiece Trouble Shooting
High Speed Handpiece
Cartridge Toggle
Toggle switches become floppy
All iM3 dental units use a unique cartridge system for the toggle switches. The toggles are used to
pressurize the water/CLS bottles and select the low or high speed handpiece. When the o-rings be-
come worn you simply push the cartridge in and turn a 1/4 turn anti clockwise. The cartridge can then
be removed from the valve casing. To install a new toggle, locate the desired position, push and rotate
a 1/4 turn clockwise. New toggles can be ordered from iM3 and installed by the user. Toggles can be
installed in the 12, 3, 6 and 9 o'clock positions. If the toggle is in the wrong position simply remove and
reposition. View this procedure on the iM3 website http://www.compad.com.au/cms/im3vet/pages/
