5. OPERATING INSTRUCTIONS AND USE

Warning: you must follow all the mentioned safety recommendations and comply with the directives about labour
accidents and risks.
F. WATER TANK
The floor saw COBRA 40/45 is supplied with a water tank of 40 litres (D, Fig.8).
HEIGHT REGULATION
The floor saws COBRA are equipped with a height regulation system which is situated on the depth crank located
on the front part of the machine (M, Fig.8). To lower the blade into the cut, turn the control lever in the sense of the
hands of a clock. To raise the blade, do it in the opposite direction as shown on the symbols of the machine (See Figure
8).
The position of the blade is shown on the cutting depth indicator. (A, Fig 8)
To avoid vibrations due to unforeseen rotations of the control lever, the machine is equipped with a simple mechanism
which blockades the control lever onto the desired position (B, Fig.8). Each time that the height regulation is being
modified, you must release the lever.
G. HOW TO USE THE SAW. TURN ON/OFF
To start the engine, proceed as follows:
WARNING: Do not expose the machine to rainfall. Always work at well illuminated work zones.
x Raise the blade until it stays some centimetres above the ground, as indicated in section
x Check the engine oil level. If too low, the engine will not start.
x Open the fuel cock.
x Close the choke. (There is no need to close it if the engine is warm or temperature is high.)
x Place the choke lever halfway.
x Turn the engine stop switch to ON position.
x Turn the machine switch to I position (C, Fig.9).
x Start the engine and pull the handle of the recoil starter.
x Let the engine idle halfway for a couple of minutes and then open the fuel cock. Then open gradually the choke
until fully open.
x To stop the engine, set the speed control lever to the low speed position and place the machine switch to O position (C,
Fig.9) There is no need to turn the engine switch to OFF position because the machine includes an ON/OFF switch
which is more comfortable for the operator.
x Close the fuel cock.
For further details, consult the engine manual.
H. CUTTING OF MATERIALS
Before starting to cut, the following recommendations are to be taken into account:
Start the engine with the blade out of the cutting zone as indicated in section
Place the machine with the blade onto the cutting line and lower the pointer guide (G, Fig.10). This will ease
advancement.
Before starting to cut, open the water tank tap (A, Fig.10). The blade must be cooled properly. An insufficient
cooling could cause an early failure and other damages.
Set the throttle to maximum and plunge the blade slowly as indicated in section until you reach the desired depth. While
the blade lowers, the saw will then have a gentle forward movement to achieve the cut.
Once achieved the desired depth, push gently the saw forward over the pre-determined cutting line. The speed of
travel will be determined by the conditions of the depth, the hardness of material and power motor. If the blade intends
to force or curve it is due to an excessive advancement. Then reduce it.
Do not try to correct the cutting line and force the saw as this will cause damage to the blade or other
components.
