Bolt-on shoe fixtures

Older models have a straight slot for a flat screwdriver. newer jigsaws have hexagonal slots for a special hexagonal key that is supplied with the tool.

Before inserting the blade into the jigsaw, the screws are loosened and once the shank is inserted into the slot, they are tightened again. To avoid misalignment, tighten them little by little and one at a time, checking the position of the saw with a straight edge. Saw blades with any shape of shank fit to this type of holder, even the obsolete models.
Replacing Saw Holders
Some sawblade mounts are much easier to replace than the parts that are found. No need to even unscrew the tool body to perform the same operation on block and screw clamps. Saw-tooth holders of this type are fixed to the end of the rod with one or two screws, which makes it rather convenient to change them. In the case of some screw holders, replacement will require the removal of the rod for a more convenient and secure holder. In the video below about the repair of jigsaws with their own hands, the process of replacing the block type of holder is visually demonstrated.
If things are relatively easy with simple saw holders, then replacing the quick-change clamp can cause some difficulties, especially for inexperienced craftsman. To begin with, such types of mounts, according to the location of the levers, are divided into radial, lateral and frontal. The first type is the most common and repair parts can be found, but the last 2 are unique and can be ordered directly from the manufacturer. In the case of radial type of mount, you can buy a repair kit and try to rebuild it by yourself, but it’s better to buy it assembled, along with the rod.
