Carvex PS420 Series

 

The Carvex jigsaw features tool-free blade changing. Used 

blades can be ejected from the saw without touching the 

potentially hot blade. New blades are inserted into the 

holder with just a simple twist. 
Choosing the correct sawblade for the task is important 

for optimal results. Refer to “

 WARNING! Always disconnect the saw from the 

power supply (power cord or battery) before making 

any adjustments to the saw or installing or remov-

ing the blade.

 CAUTION! After prolonged use, the used sawblade 

may be hot. Take care not to touch the sawblade 

until it has cooled.

1.  Unplug the saw or remove the battery. This procedure 

may require you to touch the blade with your fingers, so 

make sure the saw cannot start unexpectedly.

2.  If the splinter guard is installed, remove it as described 

.

3.  Slide the blade release lever forward until the blade is 

ejected from the spring loaded holder.

4.  Place the new blade into the diagonal slot on the blade 

holder, press it fully in, and rotate the blade until it locks 

into place. If the blade does not rotate easily, it is not 

pressed in far enough. The small tabs on the side of the 

blade must be inside the blade holder.

5.  Adjust the blade guide as described below.

The Carvex jigsaw features a lower blade guide to ensure 

that the blade stays straight and true in the cut. If the 

blade was guided only by the blade holder, like many other 

jigsaws, the upper half of the blade could flex, which would 

make it more likely that the blade wouldn’t be perpendicular 

to the workpiece. For longer life, the blade guide is carbide 

tipped to reduce wear.

 WARNING! Always disconnect the saw from the 

power supply (power cord or battery) before making 

any adjustments to the saw or installing or remov-

ing the blade.

1.  Unplug the saw or remove the battery. This procedure 

may require you to touch the blade with your fingers, so 

make sure the saw cannot start unexpectedly.

2.  Install a blade in the saw.
3.  Remove the Main Base as described on 

.

4.  Using the provided 2.5 mm hex key, loosen the adjust-

ment screw enough to ensure the blade fits loosely 

between the jaws of the blade guide.

5.  Carefully push back on the blade to ensure it is fitting 

between the parallel faces of the blade guide jaws.

6.  While wiggling the blade back and forth, tighten the 

adjustment screw until the jaws are almost touching the 

blade.

 

►

Take care not to over-tighten the adjustment screw. If 

the jaws are too tight to the blade, you will have exces-

sive wear on the jaws, and it may even prevent proper 

pendulum action.

 

►

If the jaws are too loose, the blade won’t be well guided 

in the cut. 

 

►

For optimal adjustment, you should be able to wiggle 

the blade side-to-side just a little bit.
