How to avoid kickback

SAFETY INSTRUCTIONS

•Move the blade slowly forwards and backwards to achieve a small contact area between the blade and the material to be cut. This reduces the temperature of the blade and ensures effective cutting.

•Feed down the machine in line with the blade. Pressure from the side can damage the blade and is very dangerous.

•The guard for the cutting equipment should be adjusted so that the rear section is ﬂush with the work piece. Spatter and sparks from the material being cut are then collected up by the guard and led away from the user.

WARNING! Under all circumstances avoid

!grinding using the side of the blade; it will almost certainly be damaged, break and can cause immense damage. Only use the cutting section.

Do not pull the power cutter to one side, this can cause the blade to jam or break resulting in injury to people.

Sharpening diamond blades

Diamond blades can become dull when the wrong feeding pressure is used or when cutting certain materials such as heavily reinforced concrete. Working with a blunt diamond blade causes overheating, which can result in the diamond segments coming loose.

Sharpen the blade by cutting in a soft material such as sandstone or brick.

Blade vibration

The blade can become out-of-round and vibrate if an excessive feed pressure is used.

A lower feed pressure can stop the vibration. Otherwise replace the blade. The blade must be of the recommended type for the material to be cut.

WARNING! Kickback can happen very

!suddenly and violently; kicking the power cutter and cutting blade back at the user. If this happens when the cutting blade is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique.

What is kickback?

The word kickback is used to describe the sudden reaction that causes the power cutter and cutting blade to be thrown from an object when the upper quadrant of the blade, known as the kickback zone, touches an object.

General rules

•Never start to cut with the upper quadrant of the blade as shown in the ﬁgure, also known as the kickback zone.

•Always hold the machine in a ﬁrm grip with both hands. Hold it so that the thumbs and ﬁngers grip round the handles.

•Keep a good balance and a ﬁrm foothold.

•Always cut at maximum speed.

•Stand at a comfortable distance from the work piece.

•Take care when inserting the blade in an existing cut.

•Never cut above shoulder height.

•Be alert to movement of the work piece or anything else that can occur, which could cause the cut to close and pinch the blade.

Pull in

Pull in occurs when the disc’s lower section suddenly stops or when the cut closes. (To avoid, see the heading ”Basic rules” and ”Jamming/rotation”, here below.)
