Always Read the Operators manual and be familiar with the tool before use. Check that the power lead and plug is in good condition e.g. Free from cuts and nicks and has a current tag. Check that adjustment spanners, chucks or Allen keys and locking pins have been removed before starting the tool. Keep your work area clean. Use the right tool for the intended job and never force a tool. Tie back long hair and never wear loose clothing. Ensure that the work is well held and that you are in a well balanced position. Never overreach. Maintain tools, blades and cutters in good working order (sharp). Check that toggle type switches are in the "off" position before plugging in the tool. Disconnect the tool before changing blades or cutters. Ensure that eye and ear protection complying with Australian Standards are worn. Ensure that power leads are kept 2.1 metres above floor height. Check that the tool casing is free from cracks and defects. Start a power tool when it is away from the work piece.
MAINTENANCE AND SERVICING
To prevent serious injury from accidental operation: Turn the power switch of the tool to its “OFF” position and unplug the tool from its electrical outlet, or remove the battery, before performing any inspection, maintenance, or cleaning procedures on any power tool. ELECTRIC DRILL
The electric drill is the most widely recognised tool that you will use. It is only capable of rotary motion and is used for drilling a variety of materials found on site, including timber, steel and plastic.
The electric drill has trouble drilling masonry (because there is no hammer action) and is limited to drilling mortar, soft stone, wood and metal. Electric drill
THE ELECTRIC DRILL MAY HAVE
Duel speed for drilling a variety of materials on site using various drill diameters. Variable speeds, which enables the operator to select the best cutting speed to suit the material being drilled and the size of the drill bit. Speed range adjustments are made by turning the adjusting dial located on the trigger mechanism. Copyright LAPtek Pty. Ltd. 22216VIC – Certificate II in Building and Construction (Carpentry) Page 18.

FOLDING SAW STOOL To get to this point, you have completed many tasks that displayed your competence to use the carpentry power tools required to build, the folding saw stool on the right.
You are now licensed to use the power tools. Rigidly adhere to all safety precautions, use the correct PPE at all times and enjoy using the power tools to make a folding saw stool. Folding saw stool COMMENCE MAKING A FOLDING SAW STOOL
Make the top first It will take a while for the glue to dry in the folding saw stool top , so we will make it first. Follow the steps in Task 11to make the top
Fixing stool top
ASSESSMENT 11: PLANING TIMBER EDGES FOR A FOLDING SAW STOOL
Use an electric plane to plane down the edges of three pieces of timber down to the correct size. The centre piece should be no smaller that 85mm in width. The two outside pieces should be no smaller than 65mm width. The joining edges should be flat, straight and square.
Material: 3/90 x 30 x 750mm pine.
Use the steps that follow to make the top for your folding saw stool.
Step 1 Select the grain direction of all three pieces of pine. Mark the grain direction with an arrow and number them 1.2 and 3. The arrow will also identify the face side and the number will identify their position. Use an electric plane to Planed down to 65mm, 85 mm and 65 mm plane one edge of the two outside pieces of pine straight, flat and square.
