INTRODUCTION:
 Always inspect the components before and after use for identifying any
damage. Do not use the damaged part until it is repaired or replaced if
damage is observed.
 Verify sterility prior to use. Do not use if not sterilized.
 The hub and blade should be securely fixed to the main unit.
 Test and check the saw movement and sharpness of the blade prior to use.
 The battery should not be sterilized at high temperature and/or high pressure.
Do not leave the battery in the saw for an extended period of time. Remove
the battery immediately if there is something wrong with the power during
surgery.
 Explosion hazard if batteries are exposed to flames. Properly dispose of used
batteries.
 Stop using this device immediately if the main unit gets hot or makes an
abnormal sound. Contact your distributor and return the saw for repair.
 Optimum speed is 16000r/min. Damage to the bone can occur if the speed is
too high, and cutting time will increase if speed is too low.

CHARGING THE BATTERY:
The ‘power’ and ‘charging’ LED lights will both be illuminated if the charger is
connected to the power supply.
The ‘charging’ LED will change from green to red if a battery is inserted into
the charger. This means that the battery is charging.
The LED will change from red to green after 3 hours, indicating that the
charging process is completed.
The battery should not be used immediately after charging. It should be
allowed to cool down first. The charged battery can be used at full load for no
less than 8 minutes.
The battery should be charged approximately every 15 days if the saw is not
going to be used on a regular basis.
Normally the battery can be charged and discharged approximately 150 times. After
the charger is connected to the power supply, the LED turns green. It means that the
capacity is full. Otherwise the capacity is not full. These batteries should be charged
again or replaced.
Note: Explosion hazard if batteries are exposed to flames. Properly dispose of used
batteries.

SAFE AND WORKING MODE:
The switch has a self-locking function. It has two modes: working mode and safe
mode.
Safe mode (Locked):
To put the saw in safe mode, turn the switch clockwise 90 °. The saw is now locked.
The switch cannot be pressed and the saw will not operate.
Working mode：
Turn the switch 90 degrees counter-clockwise (as in Figure 8 below). The saw will
now run when the switch is pressed. The actual speed is controlled by how far the
switch is depressed. Gentle pressure means low speed, and firmer pressure will
result in higher speed.

CLEANING AND STERILIZATION:
Cleaning：
Wipe all surfaces of the saw with a cloth dampened with a neutral enzymatic cleaner
(pH 6.0 - 8.0). Dry thoroughly.
Sterilization：
These sterilization guidelines are only recommended guidelines and may vary
among hospitals depending upon the type of sterilization equipment and possible
pathogens. These guidelines represent exposure time and not total cycle time. The
recommended sterilization parameters may be modified based on standard hospital
sterilization protocol.
