WARNING! Before cutting ensure that you wear approved safety goggles, ear defenders, appropriate dust mask if cutting
generates dust, and safety gloves. All safety instructions in Section 1 must be followed.
4.1.
Securing workpiece
4.1.1. Ensure that the saw is unplugged from the power supply and then secure the workpiece in the base vice (fig. 1.4).
We recommend that you place a block of wood (slightly narrower than the workpiece) in the vice below the item to
be cut to act as a support (fig. 3).
4.1.2. When cutting long workpieces use additional supports along the length.
4.2.

Plug the saw into the power supply and start the saw by depressing the power switch located on the handgrip (fig. 1.1). Release the
switch to stop the saw.
4.3.
Overload switch
If the saw becomes overloaded the overload switch (fig. 1.7) will cut the power to the machine. To reset, press the switch down, first
ensuring that the On/Off switch is in the Off position.
