SAFETY INSTRUCTIONS

Large work

Cuts exceeding 1 m - secure a batten along the line to be cut. The batten acts as a guide. Use this guide to make a marking cut along the entire length of the cut, 50-70 mm (2-3 inches) in depth. Remove the guides once the marking cut has been made.

Small work

First make a shallow marking cut, max 50-70 mm (2-3 inches) in depth. Now make the final cut.

Cutting sequence

First make the lower horizontal cut. Now make the two vertical cuts. Finish with the upper horizontal cut.

Remember to divide the blocks up into manageable pieces so that they can be transported and lifted safely.

CAUTION! If the upper horizontal cut is made before the lower horizontal cut, the work piece will fall on the blade and jam it.

How to avoid kickback

!

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.
