4. OPERATING INSTRUCTIONS
WARNING!
Before cutting ensure that you wear approved safety goggles, ear defenders, appropriate dust mask if cutting
generates dust, and safety gloves. All safety instructions in Section 1 must be followed.
4.1.
USING THE LOCK UP/DOWN KNOB.
(Refer to Fig.1)
4.1.1. When not in use or when being transported the cutting arm should always be locked down. To lock the arm down, pull it to its lowest
position against the return spring pressure until it is solidly against the stop. Firmly push the knob in. To release the arm, push it down
slightly, pull out the knob and gently guide it back to its top position.
4.2.
SECURING THE WORKPIECE.
4.2.1
Ensure that the saw is unplugged from the power supply.
4.2.2 Check that the back stop is at 90
°
to the cutting blade using a set square.
Ensure the back stop fixings are tight using the hex key provided.
4.2.3 To move the other jaw up to the workpiece quickly, flip the thread lock open as shown in fig.3 and slide the jaw face up to the workpiece.
Flip the thread lock back down and tighten the workpiece in the vice.
4.2.4. When cutting long workpieces use additional supports along the length.
4.3
CUTTING DEPTH
4.3.1 (See depth stop in fig.2). To adjust loosen the lock nut, adjust the stop using the hex key and retighten the lock nut. Only a small
movement of the depth stop is required to increase/decrease the depth. There is a close relationship between the locking knob and the
depth stop. After adjusting the depth stop check that the locking knob still functions correctly.
4.4
MITRE CUTTING
4.4.1 To cut at an angle loosen the vice backstop locking handle,
by turning it anticlockwise. Lift the handle vertically and turn
it clockwise to loosen the nut underneath if required. Align to
the desired angle using the graduated scale on the base
plate shown in fig.4, and retighten the vice backstop locking
handle. Place the workpiece against the backstop and move
the other jaw up to it, and securely tighten.
4.5.
ON/OFF SWITCH
4.5.1 The On/Off switch is locked in the Off position. To turn on the
saw you must press in the safety button with your thumb before
pulling the switch upwards. The switch is spring loaded and
must be held in the up position in order for the saw to continue
running. As soon as the pressure on the switch is released the
saw will turn off.

4.6. OPERATION
WARNING! DO NOT switch on the cut-off machine whilst the cutting blade is in contact with the workpiece. Bring the rotating
blade to the workpiece.
4.6.1 The cutting blade must be running at maximum speed before attempting to lower the cutting edge onto the workpiece.
4.6.2 Lower the cutting blade slowly and smoothly down towards the workpiece (avoid jerky movements).
4.6.3
Avoid subjecting the blade to excessive strain. Always ease the blade down against the workpiece (a harsh downward impact may
cause blade failure) and do not apply undue force on the handle when cutting the workpiece. Maintain a controlled cutting speed.
4.6.4 When cutting is complete, fully raise the cutting blade and release the On/Off switch.
4.6.5 Wait until the blade has stopped rotating before attempting to remove the workpiece.
