OPERATION & USE

CIRCUIT BREAKER (FIG.11):

Fig.11.

The no-volt switch is fitted with a circuit breaker. Should the

saw blade become snagged during a cut, the circuit breaker

will trip out and cut power to the motor. This will help avoid

the motor from burning out, once the blockage has been

removed and the blade is free again, push button ❀✌ to

reset the circuit breaker. Then the saw can be restarted on

the no-volt switch.

DUST EXTRACTION (FIG.12):

Dust extraction is required when using this machine to

reduce the amount of airborne dust particles. Connect the

port to a suitable vacuum cleaner (Draper Stock No.64674).

NOTE:

When making any cuts, wear safety goggles, ear defenders

and a dust mask.
