ASSEMBLY & OPERATION

Warning! Before attempting any of the following operations, make sure that the tool is switched off and unplugged and that the saw blade has stopped. Used saw blades may be hot.

Warning! Always disconnect your jigsaw from the power source when replacing blades, tilting the sole plate, cleaning or when the tool is not in use. Disconnecting the jigsaw will prevent accidental starting that could cause serious personal injury.

Blade options

Your jigsaw is designed to permit the use of many different saw tooth conﬁgurations.

Installing blades (not included) (Fig. B)

installing_blades_(not_included)_black_&_decker_jigsaw_sewing_wood_machine_js20.png

Unplug your jigsaw from the power source.
Warning! Failure to unplug your jigsaw from the power source could result in accidental starting causing serious injury.
Insert the slotted screwdriver through the access hole in the chip shield (10).
Note: Use the slotted screwdriver (not supplied) to loosen screws.
Loosen both blade clamp screws (9) and insert the saw blade (11) as far as possible into the slot in the blade clamp.
Notes:
1. Ensure the blade is nested in the groove in the support roller (8).
2. The holes in universal ﬁtting saw blades are not designed for alignment with the screw holes in the blade clamp.
Tighten both blade clamp screws (9) securely against the blade.

To remove the jigsaw blade:

Unplug your jigsaw.
Loosen blade clamp screws (9) using the slotted screwdriver.
Remove the blade.

On/Off trigger switch (Fig. C)
To turn your jigsaw ON, depress the trigger switch (1). To turn the saw OFF, release the trigger switch.

Lock-on button (Fig. D)
Your jigsaw is equipped with a lock-on feature, which is convenient when continuous cutting for extended periods is required. To lock the switch ON, depress the trigger switch (1), push in and hold the lock-on button (2), then release the trigger. Release the lock-on button and your jigsaw will continue running. Depress and release the trigger switch to release lock.

Note: The lock-on button can be accessed from left side of the handle.
Variable speed control (Fig. E)
(only JS20)
Set the jigsaw speed by rotating the variable speed control wheel (12) to the appropriate speed. Rotating the variable speed control wheel toward the rear of the jigsaw will result in slower speeds. Position the speed control dial at “1” for the slowest speed, “3” for medium speed and at “6” for the highest speed.

Vacuum port switch (Fig. F)
During normal use without the vacuum connected, the vacuum port switch (13) must be slid toward the rear of the tool . This will allow the internal motor fan to continuously blow the sawdust away from the cutting mark. When the vacuum is connected, the vacuum port switch must be slid toward the front of the tool. This positions the internal baffle to divert the sawdust through the vacuum port so it can be evacuated by the workshop vacuum.

Jigsaw Sewing Wood Machine OPERATION

Warning! Never use the tool when the saw shoe plate is loose or removed.

General cutting

Warning! Keep hands and ﬁngers away from the space between the motor housing and the blade clamp. Do not reach underneath workpiece while the saw is running.

Rest the front of the sole plate on the workpiece and align the cutting edge of the blade with the cutting line on your workpiece (Fig. G).
Make sure the power cord is out of your way and not in the path the blade will follow.
Start your saw and move it toward the workpiece. Apply enough downward pressure to keep the saw steady and only enough forward pressure to keep the blade cutting freely.

Warning! Do not force the saw. Forcing the saw may overheat the motor and break saw blades.

Bevel cutting

Bevel cutting angles may be adjusted from zero to 45° either left or right.

To adjust the bevel angle:

Loosen both sole plate pivot screws (14) until the sole plate (15) can be rotated (Fig. H).
Note: Use the 3 mm hex key supplied.
Bevel angles (17) are marked on a scale located on the side of the sole plate (Fig. I).
Slide the sole plate back. Align the edge of the motor housing (18) with the desired angle mark (17) on the side of the base, then slide the sole plate forward to engage the notches (16) into the motor housing pin.
Note: Angle marks on the sides of the jigsaw base are for reference only. Operator should use a protractor to verify angles.
Once the desired bevel angle is obtained, lock the sole plate by tightening the sole plate pivot screws.
Make a test cut in a scrap piece of material and measure the bevel angle. Adjust bevel angle if necessary.

HINTS FOR OPTIMUM USE

Sawing laminates

When cutting laminates, splintering may occur which can damage the presentation surface. The most common saw blades cut on the upward stroke, therefore if the shoe plate is sitting on the presentation surface either use a saw blade that cuts on the downward stroke or:

Use a ﬁne-tooth saw blade.
Saw from the back surface of the workpiece.
To minimise splintering, clamp a piece of scrap wood or hardboard to both sides of the workpiece and saw through this sandwich.

Sawing metal

Warning! Do not use a vacuum when cutting metal. Metal ﬁlings will be hot and may cause ﬁre. Be aware that sawing metal takes much more time than sawing wood.

Use a saw blade suitable for sawing metal.
When cutting thin sheet metal, clamp a piece of scrap wood to the back surface of the workpiece and cut through this sandwich.
Spread a ﬁlm of oil along the intended line of cut.

Plunge cutting

Warning! To avoid loss of control, broken blades or damage to the workpiece, always use extreme caution when making plunge cuts. It is not recommended to plunge cut any material other than wood. Wherever possible, drill a 3/8” (10 mm) or bigger pilot hole in the area to be cut out and start cutting with the blade in the pilot hole. This will avoid the need to plunge cut.
Note: Use only blades with 7 teeth per inch for plunge cutting.

To plunge cut an inside hole, clearly mark the cutting line on the workpiece.
Set the bevel angle at 0° then lock the sole plate.
Tilt the saw forward so it rests on the front edge of the sole plate and in a position so the blade will NOT touch the workpiece when the switch is turned ON (Fig. J).
- Note: Make sure the saw blade is inside the area to be cut.
Start the saw and slowly lower the blade onto the workpiece while making sure the front of the sole plate remains in contact with the workpiece. Allow the blade to cut through the wood.
Continue lowering the blade into the workpiece until the sole plate rests ﬂat on the workpiece. Continue sawing toward the cutting line and complete the cut as required.

Metal cutting

Many types of metal can be cut with your jigsaw. When cutting any kind of material, be careful not to twist or bend the blades. Do not force the blade. If the blade chatters or vibrates excessively, use a ﬁner tooth blade. If the blade heats excessively, reduce speed of cutting. If the blade teeth become clogged when cutting soft metals such as aluminum, use a coarser blade with fewer teeth per inch. Clamp all work ﬁrmly and saw as close as possible to the clamping point to eliminate any vibration of the work being cut.

When cutting conduit, pipe or angle iron, clamp work in a vise if possible and saw close to the vise. To cut thin sheet materials, “sandwich” the material between hardboard or plywood and clamp the layers to eliminate material vibration and tearing. By doing this, the material will be cut smoothly. Lay out your pattern or cutting lines on top of the “sandwich”.

Setup Guide

To operate the Black & Decker JS20, start by assembling the machine according to the provided instructions. Ensure all parts are securely attached before plugging it in.
For jigsaw operation, attach the desired blade and adjust the shoe as needed. Use the variable speed control to set the optimal speed for your material.
For sewing operation, thread the machine according to the sewing guide and select the appropriate needle. Use the built-in stitch selector to choose your desired stitch pattern.
Always refer to the user manual for detailed instructions on assembly, configuration, and pairing any additional accessories.
