Adjusting Blade Tension

1. Disconnect machine from power source.

2. Make sure the blade is tensioned with the release

lever in the down position as seen in Fig. 7.

3. Turn blade tension knob (Fig. 6) clockwise to

tension blade. The blade width gauge (D, Fig. 8)

indicates the approximate tension according to the

width of the blade. Initially, set the blade tension to

correspond to blade width*.

4. As you become familiar with the saw, you may find

it necessary to change the blade tension from the

initial setting. Changes in blade width and the type

of material being cut will have an effect on blade

tension.

5. Keep in mind that too little or too much blade

tension can cause blade breakage.

6. If the blade will not tension correctly once the blade

tensioner and tension knob are properly set then

you may need to adjust the blade tensioning

device.

7. Using a 2.5mm hex wrench loosen the set screw

(B, Fig. 8) in the lower bushing (C, Fig. 8).

8. Using a pair of pliers rotate the bushing (C, Fig. 8)

down only about 1 to 2 turns.

9. Replace the set screw (B, Fig 8) and check for

proper tension. Repeat the process if necessary.

*Note: When changing blades from a wider blade to a

narrower blade that you should adjust the blade tension

down to the appropriate width of the new blade. (use

blade width gauge) BEFORE disengaging (up position)

the blade release lever. Now you may proceed with the

standard method of blade changing (See “Changing

Blades” Pg 14).

Failure to do so will result in over-tensioning the blade

and possible blade breakage or even personal injury.
