Depth stop

Note.

Ensure that the depth stop

is adjusted to the correct height

before commencing operation.

The adjustable depth stop is

threaded into the rear pivot

mount at the rear. By raising

and lowering the depth stop bolt

with the a hex key (Fig. T) the

travel of the cut off wheel can be controlled. This feature is

particularly useful to prevent contact with the work bench

under guard. when a new disc is fitted or increase disc

travel as the abrasive disc wears. The depth stop should be

checked and adjusted every time a new disc is fitted.

The depth stop will require adjustment as the wheel wears.

To adjust, loosen the lock nut (anti Clockwise) and then

rotate the depth stop clockwise to allow the disc to cut

deeper, or anti clockwise to prevent full depth of cut travel.

When the correct depth of travel is obtained, ensure to hold

the depth stop screw and tighten the lock nut in a clock wise

direction to ensure the screw is locked.

DO NOT OPERATE THE SAW WITHOUT THE LOCK NUT

Operation

1. Make all adjustments including setting the vice, fence

position and fence angle.

2. Ensure that the workpiece is fully secured before starting

any cutting.

Note.

Ensure you are wearing the appropriate safety gear

including eye protection and hearing protection.

3. Check that the disc, guard and tool are in good condition.

4. Plug the cordset into the mains socket.

5. Push the lock-off button and pull the trigger to start

the tool.

6. Bring the disc down onto

the arm to clear the disc from

the workpiece, release the

trigger and the cut off saw

will stop. Please note that the disc will continue to turn

for a few revolutions even though the saw is switched

off. Keep your hands well away from the moving disc.

Disc selection. The cutting disc must match the material

to be cut. There are a wide variety of cutting discs

and careful selection will assist in the correct and safe

operation of the saw. For example, select a bar cutting

disc for cutting solid metal section and a metal stud

cutting disc for cutting steel sections. General purpose

metal cutting discs are also available but where possible

it is better to use the correct cutting disc for the task

being performed.

Abrasive cutting discs wear. The cutting discs wear so as

to constantly expose to the material being cut clean and

sharp cutting edges. This is normal for this type of cutter.

During the cutting operation apply a constant and even

pressure to the cutting arm. The disc should be constantly

cutting, and sufficient pressure needs to be applied to

keep the cutting action going. If insufficient pressure is

applied, the wheel has a tendency to clog, and the cutting

edges of the disc become blunt and the cutting process

reduces considerably. This is called glazing of the wheel

and is due to the incorrect cutting disc for the material

being cut, or the cutting rate being too slow.

Do not overload the saw. The saw should run during

the cutting operation at close to full speed. Too much

pressure being applied to the tool will slow the motor

and can cause motor failure.
