OPERATING PROCEDURES
1. Water system setUp
Use of City Water
Carefully check all water supply connections prior to start-up. Open the dental unit’s water valve. Set water
pressure between 0.1-0.5MPa (15-73 psi).
Use of Irrigation Bottle
Confirm that the irrigation bottle is filled to the appropriate level.
If water or other liquids are spilled on the irrigation pump, please wipe it off thoroughly and allow to dry
completely prior to use. If water gets inside the irrigation pump the roller may slip and fail to pump irrigation.
Do not put highly acidic liquids in the irrigation bottle. A list of approved liquids is available upon request or
you can visit www.hu-friedy.com.
2. tip connection
Your Hu-Friedy Symmetry S-Series piezo tip comes with its own tip
carrier/torque limiting wrench (the Guardian
™
wrench, Fig. 10).
Attach tip to handpiece using the Guardian wrench by aligning the
threaded end of the tip to the handpiece. (Fig. 11)
Rotate the Guardian wrench clockwise.
Complete installation of the tip by rotating the Guardian wrench
until you hear clicking.
When using the Guardian wrench without a tip previously inserted
into the tip carrier, take the following step: place the Guardian wrench
over the tip by slipping tip through the small hole in the bottom, closed
end of the tool. This will position the tip within the Guardian wrench for
safety and convenience.
3. tip removal
Hold the handpiece vertically. Insert the tip through the hole in the bottom of the Guardian wrench.
Depress wrench slightly while rotating to fully secure tip to wrench.
Turn the Guardian wrench counter-clockwise to loosen and remove tip from handpiece.
Once removed from handpiece, do not remove the tip from the Guardian carrier.
CAUTION:
Proper vibration of a tip depends on correct attachment to the handpiece. Always use the
torque-limiting Guardian wrench to ensure proper tip attachment and to eliminate over tightening of the
tip. Over tightening of the tip may result in damage to the handpiece or tip.
4. poWer on
Connect the power cord to the wall outlet. Turn on the power switch
on the control unit. (Fig. 12) Front panel will light up.
CAUTION:
Use of any wall outlets other than those of /-
10% or /- 10% may result in damage to the power cord.
