Products classification:Medical electric saw drill’s classification accords with the protection, the motor belongs to inner power B type device, charger belongs to II – B type common device; the device can not be used in flammable anaesthesia air & air mix or oxygen mix air.
Explanation:The product is the professional medical instrument, the user must be the person who has the relative technical experience or has been trained.
The product should be used after disinfecting, the product should be test before normal usage, the method: insert the battery to the main unit, press the switch lightly then the motor should be rotating, exchange the CW/CCW switch, the motor should be running, otherwise the main unit has malfunction, so stop using immediately and contact to the seller, mail the instrument to the factory to repair.
The saw blade’s installing and disassemblingPress the saw blade supporter button, insert the saw blade to the supporter, then loosen the button, the saw blade will be locked tightly. When the saw blade is blunt, you should change the saw blade in time.
The drill head’s installing and disassemblingLoosen the clamp, insert the drill head to the clamp, then tighten the clamp with the key, press the switch to run it, if need to disassemble the drill head, then loose the clamp with the clamp key to take out the drill head.
The battery assembly’s installing and disassemblingTake off the handle battery cover and put the battery glove, hold the battery with the cloth which has been disinfected, make the battery small side down, aim the concave channel to the protruding channel, take off the cloth and cover the battery cover, after the operation finished, then hold the handle and shake it, then the battery will drop automatically.
Note: Don’t drop the battery to the ground, avoid damaging it.
Operating explanation for charging and battery:The charger is not the medical instrument, during the charging period, the battery and the main unit is separate, the main unit can not be used. Connect the charger to the power supply, the power LED and charging LED will be on simultaneously. Make the battery small side down, insert the battery to the charger, the charging LED will change from green to red, that mean the charging start, after 3 hours, the red LED will turn to green, that mean the charging finished. The battery can not be used immediately after charging, wait for the battery cool then put it to the disinfecting glove and can use it in the operating room. The charged battery can be used on full load till 8 minutes.
If the battery will not be used for long time, you should charge the battery timely (15 days) to confirm the life time of the battery.
Testing the power capacity, connect the charger to the power supply, insert the socket on the battery to the charger, the LED turn to green mean the capacity is full, otherwise mean the capacity is not full, should charge it again or replace the battery. Normally, the battery can be charged and discharged for 150 times.
Note: Don’t put the battery to fire, otherwise it will explode, it should be put into the special recycle box.
On/off operation:Press the switch, the saw and drill will run; release it then stop.
The speed of the action can be controlled by the amplitude of the pressing; small means low, big means high.
Change the rotating direction ( for drill):Turn the switch to the L means CW (clockwise), R means CCW(counter clockwise )
Note: The rotating direction should be turned when the drill stopped.
Attention:1.Do check the drill heat jumping before the operating, if it is higher than the drill, so it can not be used. Check the drill sharp or not, if not should be modified. When the tool used to cut the object, then it should be fixed and without vibrating. If the drill head is broken, so replace it immediately.2.Tightly fixing drill head and saw, fix the head should use the special key. The saw should fix too with pull it to test and avoid the accident and the instrument error.
3.The battery should not be disinfected on high temperature and high pressure and let it in the unit for long time. If power break occurred during the operation (main unit stop), pull out the battery immediately.
4.If the unit is too heat or with the abnormal sound, stop using it immediately, do not disassemble, and contact to the seller or the manufacturer, and feed back the instrument to the special factory to repair in time.
5.Motor rotating rate:According to the normal occasion, if the speed is too high, then will cause burning the bone, if the rate is too low means the time is too long, so the suitable speed is very important. The 300 r/min is the better choice.
6.Disinfecting: include suffocating, high pressure and high temperature and marinating. The main unit can be disinfected by high temperature and pressure, the battery is forbidden to use this method.
Malfunction eliminates:1.The cutting saw blade is not on the right position: operating according to the manual strictly.
2.Battery failure: check the battery in time.
3.Battery uncharged: Charge it before the operation.
4.Battery lack: Check the battery before the operation
Clean:The shell of the main unit can be cleaned by water or alcohol, then keep it.
Disinfecting:Use the product after disinfection and sterilization according to the hospital’s provision.
Disinfecting method:
Method | Temperature | Time | Dry |
Quick without cloth | 129℃~134℃ | 10min | 8min |
Vacuum with cloth | 129℃~134℃ | 4min | 8min |
ethylene oxide with cloth | 49℃~57℃ | 150min | Ventilate 8 hours |
270F steam with cloth | 129℃~134℃ | 35min | 8min |
270Fsteam with cloth | 121℃~123℃ | 50 min | 8 min |
Note: Only for reference
Note:1.The battery can not be disinfected by the high temperature and high pressure.
2.All the method above is reliable, but the time and the temperature should be controlled in the correct range strictly, otherwise that will damage the main unit! The charger and battery can not be disinfected.
3.We suggest that use the formalin suffocating method that widely used in mostly hospital. With the cankerous, but it will not damage the main unit immediately, so the steam is less or disinfected by ethylene oxide, then there will be no steam and no causticity, then that is the best disinfecting method.
