Overview

The cut off saw is used for cutting steel such as pipe, 

box section, rectangular, angle iron and steel bars. 

The saw can cut at angles from 0° to 45° left and 

right, it features a two position fence that permits an 

extended cutting range. The quick release vice allows fast 

adjustment whilst the lock-off button prevents accidental 

operation.

Attaching the rubber feet

1. Tilt the saw onto its side.
2. Take the rubber feet and 

insert 1 rubber foot into the 

matching slots on the base 

of the saw.

3. Ensure the rubber feet are 

fully inserted into the slots.

4. Repeat for the other side 

and place the chop saw back on its base.

Attaching the rear spark shield

1. Loosen and remove the hex bolt, flat washer and star 

washer at the back of the saw using the 5mm hex key 

supplied.

2. Place the flat washer over the hex bolt and then fit 

the hex bolt through the spark deflector, place the star 

washer over the hex bolt so it is in between the spark 

deflector and the cut off saw. Place the spark shield in 

the correct position and tighten the hex bolt.

3. Tighten the hex bolt to secure the spark shield in position.

Adjusting the vice

The vice can be adjusted quickly by loosening the vice lock 

release lever and pushing forward.
1. Place your workpiece in 

between the fence and vice.

2. Lift the vice lock release lever 

and push the vice forward.

3. Once the vice hits the 

workpiece move the vice lock 

release lever back down.

4. Rotate the vice handle in a 

clockwise direction to secure 

the workpiece in position.

5. To remove an object from 

the vice, rotate the vice 

handle in an anti-clockwise 

direction until the vice jaws 

are loose. The work piece 

can now be removed, the 

vice lock release lever can 

also be lifted to slide the vice back quickly.

Note.

 The vice lock release lever cannot be lifted until the 

vice jaws are loose.

Adjusting the cutting angle

1. To change the cutting angle loosen the 2 hex screws 

securing the fence using the 8mm hex key supplied.

2. Move the rear fence to the desired angle using the scale
