The Instruction of Electric Plaster Saw
I. The composing and usage of the product:
Electric Plaster Saw consists of electric main engine,
transmission shaft, shaft installing sleeve, eccentric shaft,
axletree, transmission pliers, circular saw, linearity saw and
housing, front cover, setscrew, power line, wire plug, and so on.
This product applies to take down the plaster cast after the
fixation and diaplasis of the orthopedics operation in the
hospital.
II. Structural feature and operational principle:
Electric Plaster Saw can attain the aim of taking down the
plaster cast by using power supply to make electric engine
revolving, the twirl of eccentric shaft will drive transmission
pliers to form a to-and-fro swing and saw the plaster cast; there
is no harm to the skin of the wounded in use.
This electric machine adopts double insulation to protect
the device, so that it can guarantee the safety of the operator and
the wounded. This machine possesses distinguishing features of
strong power, light design, stable operation, small vibration, low
noise, safety and credibility.
III. Normal working conditions and basic parameters:
A). Normal working conditions:
Environmental temperature: 5~40℃;
Relative humidity80%;
The voltage of power supply: 220V22V;
The frequency of power supply: 50HZ1HZ.
B). Basic parameters:( when swinging in no-load.)
The oscillation angle of the plaster saw: 6°±1°;
The frequency of the oscillation ( revolving in no load):
15000 times/min2250 times/min.
Noise in no-load90Db(A);
The temperature rise in no-load: the temperature rise of the
housing is not more than 25℃ after 3 minutes’ operation.
IV. Method of application:
A). Before using, check to see if the saw blade is flat, the
saw teeth are full, and the installation is firm. When installing
the saw blade, you only need to tighten up the multi-color crown
clockwise by using a 5mm inner hexagon spanner, and then can
operate it.
B). Before the operation, using formalin to disinfect the
Plaster Saw, then connect the electric main engine to the power
supply, flip the switch of the main engine and start up the
machine.
C). During operating it, you should clutch the saw and lay it
slowly on the plaster that needs cutting, then cut down apeak along
plaster surface. If you’re not very sure, don’t cut the pluster to
its bottom at one time (though this saw has the protective function
to the soft tissue).
D). Cut down apeak along plaster surface, lift and move
forward the saw, then put it on the lower part of the plaster that
need cutting, do it again as the aforementioned process until the
task is finished.
E). When the saw teeth become blunt after long term usage,
you only need to loosen the multi-color crown counterclockwise by
using a 5mm inner hexagon spanner and revolve the saw blade, then
tighten up the multi-color crown clockwise and can use the saw.
V. Caution:
A). The plug of the wire should install to the safe triporate
socket with the same specification. The safe socket should be
earthed to guarantee the safety in using the electricity.
B). Before using, check to see if the saw blade is flat, the
saw teeth are full, and the installation is firm.
C). Don’t press the saw too hard in use, you should increase
the pressure properly when the saw blade is swinging.
D). When the saw blade is stuck suddenly in the cutting part
of the plaster, you should cut off the power supply and get out
slowly, rather than turn on and turn off the switch of the power
now and then, for this can cause the motor load of the electric
engine increase and decrease abruptly, so as to damage the engine.
E). In use, the temperature of the engine housing will
increase over time. If the housing is too hot, you should stop
using it, and wait to use it again after it cools, or else the
engine will easily be burnt by the high temperature.
F). If there is abnormal sound, too much vibration or
decrease of the motor load, and so on,you should send it back to
the producer or the electrician to check and repair.
VI. Maintenance
A). Periodically check the insulating property of the main
engine to ensure the safety utilization of electric power.
B). Periodically check the movements of every part of the
saw. If the engine works well but there are malfunctions with the
mechanical parts, you can check the structure of the mechanical
parts, then replace or repair the parts as the factual situation.
After repair, you should add new #1 MOS2 lubricating grease to
prevent the abrasion of the transmission parts and the affect to
the service life due to the lack of grease.
VII. After-sales services commitment:
This saw will be repaired free within half a year, if it
lies in the quality of t
