Safety Recommendation For The Motor; Starting And Use Instructions; Water Tank - Sima COBRA-40 Manual De Instrucciones

Blades must be cooled. Accordingly the floor saw COBRA 40/45 has a water spray system that ensures a
steady stream of water.
The blade safeguard of COBRA-50 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:

Fig.4.
x For other safeguards, loosen the screws A, Fig.4.1 holding the safeguard to the chassis. It is not necessary to
completely remove it. Raise the safeguard to the maximum onto its rotation axis. B, Fig. 4.1

has two flat faces to allow placing the spanner without any trouble.
x Loosen the screw of the blade shaft (T, Fig.4) with the 36 mm flat spanner (M, Fig.4) and remove the outer flange
(E, Fig.4). WARNING: the nut is left-threaded.
