3. TRANSPORT
For short distances, the floor saw COBRA 50 can be transported onto its own wheels. Raise the blade fully and
move the saw manually.
When the machine must be lifted, use the hook located on the front part. It will be then easy to fix steel
cables or chains C, Fig. 2. The transport to be used should ensure the machine safety.
WARNING: use highly- resistant cables or chains (bear in mind the weight of the machine and see the
metal label of the machine).When you put down the machine, do it gently and avoid any strong bumps on
the wheels that could damage other components.

4.2 ASSEMBLING THE ELEVATION WHEEL
The height adjusting wheel, C, Fig.3 is mounted in factory without its handle A, Fig.3 for packing reasons
and to avoid possible shocks during transport. To assemble this handle, you need to place it on the wheel, fastening it
with a 6 mm Allen key D, Fig.3. The handle screwed spot is the housing for the Allen key.
4.3 PLACING THE BLADE
A good choice ensures a good performance and agood final result.
Blades must be cooled. Accordingly the floor saw COBRA 60 has a water spray system that ensures a steady
stream of water.
The blade safeguard of COBRA 60 can be lifted from one of its ends: assembly and blade replacement are
then quick and easy.
To place or replace the blade, you must proceed as follows:
•In machines with a steel safeguard, loosen the protection locks P, Fig.4 and open the foldable part of protection.
For installation or replacement of the disc, proceed as follows:
•Loosen the screws C, Fig.4 holding the safeguard to the chassis.
•Block the rotation of the blade shaft with a flat spanner L, Fig.7 supplied with the machine. The blade shaft has two
flat faces to allow placing the spanner without any trouble.
•Loosen the screw of the blade shaft T, Fig.4 with a flat spanner M, Fig.4 and remove the outer flange E, Fig.4.
WARNING: the nut is left-threaded.
•Place the blade on the shaft and coincide the small hole with the dowel pin of the inner flange plate. (I, Fig.4).
•Place the outer flange plate making sure the dowel pin passes through the blade into the rear flange plate.
•Tighten firmly the safeguard using the two flat spanners provided.
•Make sure that the rotation of the blade is always correct. It must coincide with the arrow marked on the
blade as well as with the one marked on the blade safeguard.

7.5 STARTING AND STOPPING USING MOTOR 13HP (COBRA-60/G13H)
Proceed as follows:
•Raise the blade some centimetres from the ground.
•Check the engine oil level. If too low, the engine will not start.
•Open the fuel valve in the engine.
• Close the throttle. (Not necessary to keep it open if the engine is hot or the temperature is high).
• Place the throttle control G, Fig.5 acceleration position.
• Turn on the engine switch.
• unlock the stop button E, Fig.5 turning and moving it up. This switch is in addition to the switch engine and
allows more convenient functions STOP / START.
• Start the engine pulling the recoil starter handle.
• Let the engine warm up at low revolutions and then open the throttle and the throttle control to put in the
position of acceleration for the job intended.
• To stop the engine, raise the disc above the ground, decelerating completely and lock the push button E,
Fig.5 pushing it down. This switch is an emergency stop type. It is not necessary turn the switch in position
OFF to make stop the machine.
• Close the fuel valve in the engine.
For details on operations in the engine, see your instruction book.
7.6 STARTING AND STOPPING USING MOTOR 20HP (COBRA-60/G20H)
The 20HP engine models come with electric start and proceed as follows:
