6 ADDITIONAL SAFETY INSTRUCTIONS FOR PLUNGE SAWS

 Make sure that the mains voltage matches the specifications on the type plate.
 Persons with restricted physical, sensory or mental capabilities are not allowed to use the

plunge saw unless they are supervised and instructed by a guardian.

 Never leave the powered-on saw unattended and keep them out of reach of children and

persons in need of supervision.

 Do not bring your hands in the cutting area and the saw blade.
 Keep in mind that even a worn saw blade is still very sharp. Always grasp the saw blade

on the sides. Do not fling the saw blade and do not drop it.

 Never use the plunge saw with grinding wheels.
 Do not grip underneath the workpiece. The protective cover cannot protect you from the

saw blade under the workpiece.

 Adjust the cutting depth to the thickness of the workpiece. It should be visible less than a

full tooth height under the workpiece.

 Do not cut very small workpieces. When cutting round wood, use a device which secures

the workpiece from twisting. Never hold the workpiece to be cut in your hand or across
your leg. It is important to secure the workpiece properly to minimise the risk of physical
contact, jamming of the saw blade or loss of control.

 Hold the saw only by the insulated gripping surfaces when performing an operation

where the cutting tool may come into contact with hidden power lines or its own device
cable. Contact with a live wire also exposes the metal parts to tension and leads to an
electric shock.

 Use always saw blades in the correct size and with suitable locating bore. Saw blades that

do not match the mounting parts of the saw will run unevenly and lead to loss of control.

 Never use a damaged or incorrect outer flange or a damaged clamping screw. The outer

flange and the clamping screw have been specially designed for your saw for optimum
performance and reliability.

 Start the plunge saw and begin cutting when it reaches the full idling speed.
 Never brake the saw blade using lateral pressure after switching it off.
 Set the saw aside only when the saw blade comes to a standstill.
 Do not expose the saw to high temperatures, humidity and strong shocks. The saw can be

damaged as a result.

 Hold the saw firmly with both hands and bring your arms into a position in which you can

resist the kickback forces

7 CAUSES AND PREVENTION OF KICKBACK

 A kickback is the sudden reaction as a result of a stuck, jammed or misaligned saw blade

which leads to an uncontrolled saw to be lifted and moved from the workpiece out in the
direction of the operator.

 A kickback can occur when the saw blade gets stuck or jammed in the saw gap. The saw

blade is blocked and the motor force repels the circular saw in the direction of the
operator.

 A kickback can occur when the saw blade becomes twisted or misaligned in the saw

groove. As a result, the teeth of the back edge of the saw blade can get stuck in the
surface of the workpiece, whereby the saw blade is moved out of the saw gap and the saw
jumps back in the direction of the operator.

 A kickback is the result of incorrect or faulty use of the saw. It can be prevented by

appropriate precautions as described below.

 Hold the saw firmly with both hands and bring your arms into a position in which you can

resist the kickback forces. Always hold the saw baldes on the sides, never bring the blade
in line with your body. In a kickback, the saw can jump backwards, but the operator can
control the kickback forces if appropriate measures were taken.
