 SLIDING COMPOUND MITRE SAW

Adjusting Bevel Angle

This mitre saw is capable of dual bevel angles which means the saw head can be inclined 
or tilted towards the right or the left. To adjust the saw head to any bevel angle;

Loosen the bevel lock knob (A) 

Fig.9

 and pull the positive stop adjustment knob (B)  

outwards as shown. At this point, the saw head can be inclined to any angle you desire. If you 
require a predetermined bevel angle of 0˚, push the adjustment knob inwards and pivot the 
saw head until it stops at 0˚. Once the desired bevel angle is obtained, it is very important that 
you retighten the bevel lock knob (A).

Depth Of Cut Stop Adjustment

In its normal position, the depth of cut stop 

Fig.7

 permits the saw blade to cut right through a 

workpiece. When the saw arm is lifted, the depth of cut stop (A) 

Fig.7

 can be slid over towards 

the front of the saw so that the depth adjustment screw (B) contacts the stop as the saw head 
is lowered. This resricts the cut to a “adjusted depth” in the workpiece. The depth of cut can 
be adjusted with the adjustment screw and locked in position with the lock nut (C)

Setting The Blade Square With The Table

1.

 Make sure that the electrical plug is removed from the main power supply.

2. 

Push the saw head down to its lowest position, then pull and turn the head release knob to 

hold the saw head in the transport position. 

3.

 Loosen the mitre lock handle.

4.

 Rotate the table until the pointer is positioned at 0˚.

5. 

Retighten the mitre lock handle.

6. 

Loosen the bevel lock knob at the rear of the machine and set the saw arm at 0˚ bevel (the 

blade at 90˚ to the mitre table). Tighten the bevel lock knob.

7. 

Place a square (A) 

Fig.10 

against the table and the flat part of the blade body.

NOTE: 

Make sure that the square contacts the flat part of the saw blade body, not the teeth.

8.

Rotate the blade by hand and check the blade-to-table alignment at several points.

9. 

The edge of the square and the saw blade should be parrallel.

10.

 If the saw blade angles away from the square, adjust as follows;

11.

 Make sure the positive stop adjustment knob (A) 

Fig.11

 is pushed in all the way and the 

bevel lock knob (B) is fully tightened. Loosen the two hex. screws (C & D) inside the pivot 
bracket using a hex. key. 

12.

 Loosen bevel lock knob (B) and adjust the head of the saw in or out to bring the saw blade 

into alignment with the square. 

13.

 Once perfectly aligned, retighten the bevel lock knob (B) and the two hex. screws (C & D) 

inside the pivot bracket. Recheck the alignment.

14. 

Readjust bevel pointer (B) 

Fig.11

 to line up with the 0º on the bevel scale.

Adjusting The 45˚ Stop Bolts

After setting the blade square with the table, the left and right side 45˚ stop bolts will need to 
be adjusted. 

1.

 Loosen the hex. nut and cap screw (F) 

Fig.11

.

2.

 Tilt the head completely to the left side.

3. 

Place a 45˚ combination square against the table and the flat part of the blade body.

4.

Once the head is at a perfect 45˚ angle,tighten bevel lock knob(B),then tighten the cap 

screw(F)against the bevel lock knob(B)shaft and tighten hex. nut(F).

5.

 Repeat the above steps for the right side 45˚ stop bolt using the hex. nut and cap screw (E).
