(2) Changing Contra Angle Head
The contra angle head can be connected with
the motor handpiece at 6 adjustable head
positions. Align the positioning pins of the contra
angle head with the positioning slots of the
motor handpiece and insert the head until they
click. When removing the contra angle head, pull
it out axially.
(3) Mounting and Removing File
Insert file to contra angle head, lightly turn the file until it engages with the latch mechanism.
Push it inward to click.
File Removal, depress the push-key and pull out the file.
• Turn OFF the power to remove or attach the contra angle head.
• Do not connect other than NSK F-type contra angle handpiece.
(In the EU, use the CE-marked handpiece.)
• Check that the contra angle head is securely connected to the motor handpiece.
CAUTION
• When attaching and detaching the file, turn off the power beforehand.
• After the file is locked in place, lightly pull out the file to make sure the file is locked.
• Always clean the shank of the file to be installed before use. Allowing dirt to enter the
chuck could cause loss of concentricity and deterioration of chucking force.
• Do not exceed the rotation speed recommended by the file manufacturers.
CAUTION
• When the power lamp for the charger does not light up, the internal fuse may be
faulty. In this case please contact your dealer.
• Be careful of handling when placing the motor handpiece in to the charger. Do not
force the handpiece into the charger. Otherwise, failure may be occur.
• If the power cord is inserted into the jack or the power switch is pressed with
unnecessary force, the cord or switch may be broken or a short-circuit may occur.
• Never use the battery charger for anything other than the motor handpiece of this
product.
• The charging normally takes approx. 90 minutes, but it depends on battery use
conditions, battery freshness, ambient temperature, etc. Older batteries are especially
prone to significantly shorter charging and operating times.
• Batteries may slightly warm up during charging, but this is not a failure. If the
handpiece is inserted or removed into/from the charger at short intervals, (approx. 5
minutes) charging cannot be properly completed and the battery compartment may
feel hot. We recommend that you charge batteries for as longer periods as possible.
• The power of the motor handpiece should not be turned on immediately after it has
been removed from the charger, wait at least approx. 2 seconds before you switch on
the power.
• Completely discharged batteries cannot be charged. Replace them with new ones.
• Do not put anything (metal or other devices such as wire, safety pin, or coin) other
than the handpiece on the charger. Otherwise, burn or failure may result due to heat
generation.
• The temperature of the batteries is measured during charging. Proper charging cannot
be performed if the charger is placed in an environment which is subject to sharp
temperature change (next to window, subject to direct sunlight, near air outlet of fan
heater). Place it in a place where temperature change is minimal.
• Charging may not be started in the following case.
· The temperature of the batteries is excessively high or low.
(Lower than approx. 0°C or higher than approx. 40°C)
· Battery voltage is sufficient
· Battery voltage is abnormal
