Hold the motor and the handpiece, then pull apart. (Fig. 5)
CAUTION
• Do not connect or disconnect the handpiece until the motor
has completely stopped.
• Make sure that the motor and handpiece are securely
connected. The motor and coolant air pressure may cause
the handpiece to jump out of the motor, which could result
in injury.
• Connect ONLY to E type handpieces (ISO 3964 (EN ISO
3964)).
5 Forward / Reverse Rotation
1) Forward Rotation: Turn the
FWD/REV Change Ring to “F”.
(Fig. 6)
2) Reverse Rotation: Turn the
FWD/REV Change Ring to “R”.
(Fig. 7)
3) When the FWD/REV Change

water using a soft bristled
brush for one minute (Fig.
13).
Fig. 13
2) Rinse the motors under running tap water for 20 seconds.

10
3) Remove any moisture from the motor with compressed air
and wipe off any external moisture using a dry lint free
cloth.
Under appropriate lighting (natural office lighting, 500 lx or
higher), inspect the motor for blood or other debris. If any
visible debris remains, repeat the process until the motor is
visually clean.
4) Wipe the exterior of the
motor clean using a cloth
moistened with disinfectant
or ethanol with a
concentration of 60-90%
(Fig. 14).
Fig. 14
When using disinfectant, follow the instructions given by the
manufacturer of the disinfectant.
Use a state-sanctioned disinfectant with proven bactericidal,
fungicidal, and virucidal properties.
The following disinfectants can be used in the United States
and Canada.
CaviCide®, CaviWipes®(manufactured by Metrex)
After cleaning, if residual moisture is present, wipe it off with
a dry cloth or blow it off with compressed air (≤50psi
(0.35MPa)) until there is no moisture in the interior and
exterior.
When blowing off with compressed air, cover the motor with a
cloth to prevent scattering of water. Proceed to “7-3
Lubrication”.

7-3 Lubrication
■PANA SPRAY Plus (Lubricating the Interior)
1) Attach a tip nozzle* to the
nozzle of the PANA SPRAY
Plus.
* Tip nozzle is the accessory of
the PANA SPRAY Plus.
2) Shake the can 3 or 4 times,
and insert the tip nozzle
into the drive air port of the
motor while holding the
motor with a cloth.

7-4 Packaging, Sterilizing, and Drying
1) Insert the motor into an FDA-approved sterilization pouch
that conforms to ISO 11607-1 (EN ISO 11607-1), and seal
the pouch.
2) Perform steam sterilization with the following conditions.
Type Gravity Displacement Dynamic Air Removal
Temperature 270°F (132°C) 270°F (132°C)
Full Cycle Time 15 min 4 min
Drying Time 30 min 30 min
CAUTION
• Use an FDA-approved steam sterilizer to perform
sterilization.
• Follow local rules, regulations, and guidelines regarding the
reprocessing of devices.
• Do not touch the product immediately after steam
sterilization as it will be very hot and must remain in a
sterile condition.
• Do not perform steam sterilization on the product with
other instruments even when it is in a pouch. This is to
prevent possible discoloration and damage to the product
from chemical residue on other instruments.
• Clean and lubricate the motor prior to sterilization. If blood
remains on the internal surface it can become clotted and
cause product failure.
• Do not heat or cool the product too quickly. Rapid change
in temperature could cause damage to the product.

13
CAUTION
• Be sure to use sterilizers that can perform sterilization no
higher than 275°F (135°C). In some sterilizers, the
chamber temperature may exceed 275°F (135°C). Do not
use these sterilizers as failure of the motor could occur.
Contact the sterilizer manufacturer for detailed information
about cycle temperatures.
• Steam sterilization is recommended for the product. The
validity of other sterilization methods (such as plasma
sterilization or EOG sterilization) is not confirmed.
7-5 Storage
Store the product in a dry, clean location.
CAUTION
• After the sterilization and drying cycles are complete,
remove the motor immediately from the sterilizer to store it.
• Store the product in a well ventilated place out of direct
sunlight and within the range of temperature, humidity and
pressure specified in “10. Specifications”.
• Sterilization is not guaranteed after the sterilization
retention period specified by the manufacturer and seller of
the sterilization pouch has elapse.
If the sterilization retention period has elapsed, perform
sterilization again with a new sterilization pouch.

8 Maintenance
If a deteriorated O-ring makes
it difficult to attach the
handpiece, replace the O-ring.
Using a needle or other pointed
tool, remove defective O-ring
from the motor insert section,
and fit new O-ring into the
O-ring groove. (Fig. 16)
