6.4 Switch/Safeguard against overloading/Motor brake

The switch does not click in as long as the machine is not connected to the electric mains. In case of a power cut the switch will automatically be opened through a built- in relay. This means that the saw has to be switched on again after regaining power supply. In case of the motor being overloaded, a built-in automatic circuit-breaker will switch it off. Overloaded and thus overheated motors should not be re-started until 10 minutes have passed. Saws with alternating current have a built-in force driven brake (braking motor) which is designed to prolong the life of the saw. Brakes have to be changed when the slowingdown effect is reduced and the stopping time exceeds 10 seconds.

Please ask a specialized dealer. An ineffective break will increase the danger of accidents!

6.5 U.K. Industrial Use

Within the U.K., this machine falls under the Woodworking Machinery Regulations 1974, under which certain operations, e.g. grooving, rebatting, tenoning and moulding are prohibited without special guards. For your own safety it is recommended to follow the instructions given in the Health and Safety at Work booklet No. 41, entitled "Safety in the Use of Woodworking Machines" and "A Guide to Woodworking Machinery Regulations" HS(R)9. Both publications are available from Her Majesty's Stationary Office and other bookshops.

7 Operating/Setting

7.1Setting the riving knife

-Before starting work, always pull the plug from the socket !

-The riving knife must be fitted all the time, apart from insertion (charging) cuts (point 9.3 of the operation instructions).

The riving knife has to be fixed so that the distance from the saw blade edge is not more than 10 mm radially, and 2 - 3 mm in height.

- The riving knife prevents the locking of the kerf behind the saw blade and the jamming of the workpiece.

7.2 Setting/Application of the protective hood

Set blade guard only with blade at complete standstill.

Danger of injury!

In case of through-cuts, longitudinal or across, the protective hood must be fitted in a way that its distance to the workpiece does not exceed 8 mm.

The protective hood must be fitted all the time, apart from insertion- or concealed-cuts Para. 9.2 and 9.5 of this manual. U.K. users see para. 6.5).
