Checking and changing the saw blade

• Only saw blades conforming to the specifications
contained in these operating instructions may
be used.

• Saw blades made of high alloy, high speed steel
(HSS steel) should not be used.

• Only sharp saw blades in perfect working
condition should be used; cracked or bent
saw blades should be discarded and replaced
at once.

• Ensure that the saw blade is securely fixed and
rotates in the correct direction.

Special applications

• When cutting narrow workpieces
(width less than 80 mm) longitudinally,
use a rip fence guide along the longitudinal edge.

• When sawing with the workpiece clamped tight,
devices should be used to prevent the workpiece
kicking back.

• When sawing circular sections of wood use
a device to hold the workpiece steady on both
sides of the saw blade to prevent slipping.

• Ensure that pieces of wood sawn off the
workpiece cannot be caught up by the teeth of
the saw blade and thrown in the air.

Guard against kickback

• Kickback occurs when the saw begins to stall
rapidly and is driven back towards the operator.
Release the switch immediately if the blade sticks
or the saw stalls.

• Keep the saw blades sharp.

• Supports large panels near the cutting area.

• Use a fence or straight edge guide when ripping;
do not force the tool.
