Quick-Change Blade Mechanism
Higher-end models, such as the Linefinder Orbital Jigsaw, feature a clamping lever to hold the saw blade. To change a blade, switch off the jigsaw, unplug it, and let the used blade cool down. Pull up the saw-blade locking lever and let the used blade fall out with a slight shake. Turn the jigsaw upside down. Hold the fresh blade with its teeth forward; insert the blade shank into the blade holder as deeply as it will go. Release the lever and wiggle the blade to confirm that it's snugly in place. For models with rollers, such as the Accu-Trak, nestle the blade against the rollers.
Clamp or Hex Screws
Loosen the pair of screws -- on the front of the mechanism of models such as the single-speed jigsaw -- a full turn counterclockwise with a flathead screwdriver, but do not remove them. The used blade will fall out. Insert the new blade fully into the clamp. Lightly tighten each screw alternately and then fully. On older models, you may find a single hex screw on the side of the blade. Loosen this enough to remove the blade, and then insert a new blade carefully so the teeth face forward. Retighten the screw.
Hi Rebecca, I hope this helps;
BLADE INSTALLATION
Set the blade orbit selector lever to position III.
Push blade change button downward as far as
it will go and turn the top handle three turns
counterclockwise (viewed from the top of the
tool).
Insert the blade into blade plunger at a 90°
angle to the cutting direction. With a slight
upward pressure, turn the blade teeth forward
(direction of cut) and guide the back of the
blade into the groove in the center of blade
roller guide. Pull gently down on the blade to
seat the blade tabs in the plunger.
With the blade in the proper position, turn top
handle clockwise until a noticeable "Click" sound
is heard, indicating that the blade is locked in
place.
Push blade change button upward to its
original position (flush with the top of the top
handle), and the saw is ready for use.
Removing the blade is essentially the reverse
of the installation procedure, however, take
note that once the blade change button is
loosened, gently push the blade upward to
release the blade tabs from the plunger.
How do I change the blade on the quick change/instant change knife?
Warning: Blades are sharp and can cause serious injury. Be extremely careful when handling blades. Wear eye protection and dispose of used blades properly, such as wrapping in duct tape.
FULLY EXTEND THE BLADE.
Press down and forward again on the slide button until the button is in the full front of the top slot (0 through 3 in the below picture).
Note- the blade must be extended beyond the 3rd detent position. This will cause the slide button to remain in a down position, allowing the blade release button to operate.
PRESS AND HOLD THE BLADE RELEASE BUTTON ON THE FRONT SIDE OF THE KNIFE. (Step 4 in the below picture)
Note- if the blade is not fully extended beyond position 3) , the blade release button will not work.
Remove the old blade carefully.
Insert new blade.
NOW, RELEASE THE BLADE RELEASE BUTTON. ENSURE THE BLADE IS LOCKED IN PLACE. If the blade does not retract, try carefully giving a slight tug on the blade to reseat.
you need to lift up on the knob to loosen the spindle and remove/install the blade. To install the blade you might need to turn it some and push up and when it is straight then you need to turn the knob while holding up on it till it is snug and then push the knob down.
This saw uses a tool-free blade change.
1. Unplug the jigsaw
2. Place your finger on the lower edge of the see through blade guard, and pull it forward until it locks up in place
3. Lift the tool-free blade change holder (bright yellow piece above the blade), and insert the blade into the slot of the tool-free blade change holder.
4. Release the tool-free blade change holder to lock the blade in place.
5. Pull down on the blade to verify that the blade is securely locked in place. The teeth of the blade should be pointing forward and down.
5. Put the blade guard back down.
You can use with both 'T' & 'U' shanked blades.
Feel free to ask me any other questions about this saw.
If the saw doesn't have a locking mechanism for changing the blade then you will have to jam a piece of wood in the teeth of the blade so that it cannot turn. Remember safety first. Ensure the saw is unplugged and wear leather gloves when changing the blade. Use a socket or wrench to loosen the nut that holds the blade on and remove the blade. Use the reverse procedure to tighten the blade.
the cover comes with certain blades. it's there to help ice & snow from freezing to it. You can't take it off and change it. If you have trouble removing the blades, most parts stores change them free (if you buy them there)
the blade shape can not be changed they are heat treated and if bent they will break, the only way to change the blade height is by changing the blade adapter.
remove the blade guard, should be a big nut holding on blade remove that nut install new blade, make sure the rotation arrow on your new blade is going same direction as old blade reinstall the big nut and washer , put guard back on you should be set! good luck
