Power Tool Safety Rules

WARNING

Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

Work Area

Keep your work area clean and well lit.

Cluttered benches and dark areas invite accidents.

Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.

tools create sparks which may ignite the dust or fumes.

Keep by-standers, children, and visitors away while operating a power tool.

Electrical Safety

Double Insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way.

WARNING

grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and other masonry products, and

• Arsenic and chromium from chemicallytreated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Operating Instructions

TRIGGER "ON-OFF" SWITCH

TO TURN THE TOOL "ON" squeeze the trigger switch. TO TURN THE TOOL "OFF", release the trigger switch, which is spring loaded and will return to the "OFF" position automatically.

Your tool is equipped with a variable speed trigger switch. The tool can be turned "ON" or "OFF" by squeezing or releasing the trigger. The speed can be adjusted from the minimum to maximum nameplate SPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1).

The "Lock-ON" button, located in the handle of your tool allows for continuous operation at maximum SPM without holding the trigger (Fig. 1).

TO LOCK TRIGGER "ON": squeeze trigger, depress button and release trigger.

TO UNLOCK THE TRIGGER: squeeze trigger and release it without depressing the "LockON" button.

ELECTRONIC FEEDBACK CIRCUITRY (EFC)

The internal electronic feedback system helps to keep the no load speed virtually constant between no-load and load conditions.

The stroke rate may be adjusted as described earlier under “Variable Speed Dial”. The best results for a particular application are determined by experience, though as a general rule, slower speeds are for denser materials and faster speeds are for soft materials.

BLADE STORAGE COMPARTMENT

Your Jigsaw is equipped with a blade storage compartment in the dust port of your saw (Fig. 5) . To remove, pull compartment out of dust port in direction of arrow.

Always make sure the blade storage compartment is securely in the dust port to prevent blades from falling out.

DUST EXTRACTION

Your jigsaw is equipped with a dust port for dust and chip extraction.

To use this feature, remove blade storage compartment and move dust blower switch to the “OFF” position “O” (Fig. 6).

Attach vacuum hose (optional accessory) to the dust port, and connect opposite end of the hose to a shop vacuum cleaner.

BUILT-IN WORK LIGHT

(Models 4485 & 4580 only)

Your tool is also equipped with a light that turns on automatically when the switch is activated, for better visibility when cutting (Fig. 7).

ORBITAL ACTION MODELS

Orbital Action models, have a lever (Fig. 8) that will regulate the orbital action from "Smooth" position for normal up and down motion to maximum orbital action for faster cutting in softer materials.

Scrolling saws permit 360˚ rotation of the saw blade without turning the saw, so intricate designs may be cut with minimum effort. To permit rotation of plunger turn lever, (Fig. 10)

Cutting Tips

Face the good side of the material down and secure it in a bench vise or clamp it down. Draw cutting lines or designs on the side of the material facing up towards you. Then place the front edge of the saw foot on the work and line up the blade with the line to be cut. Hold the jigsaw firmly, turn it on, and press down (to keep the saw foot flat against the work) as you slowly push the saw in the direction of the cut.

Build up cutting rate gradually, cutting close to the line (unless you want to leave stock for finish sanding). As you cut you may have to adjust or relocate the vise or clamps to keep the work stable. Do not force the saw or the blade teeth may rub and wear without cutting and the blade may break. Let the saw do most of the work. When following curves, cut slowly so the blade can cut through cross grain. This will give you an accurate cut and will prevent the blade from wandering.

CUTTING WITH A STRAIGHTEDGE

Always use a rough cut blade when possible. Clamp a straightedge on the work parallel to the line of cut and flush with the side of the saw foot. (Either first mark the line of cut and

then position the straightedge parallel and at the same distance as between the blade and the side edge of the foot or first mark the side edge of the foot and then clamp the straightedge on the mark and parallel to the cut line Fig. 12).

On models with the scroll feature, it is advised to lock scroller knob.

As you cut, keep the saw foot edge flush against the straightedge and flat on the workpiece (Fig. 12).

making rough openings in softer materials. It is not necessary to drill a hole for an inside or pocket cut. Draw lines for the opening, hold the saw firmly, tilt it forward so that the toe of the saw foot rests on the work, but with the blade well clear of the work. Start the motor, and then very gradually lower the blade. When it touches, continue pressing down on the toe of the saw foot slowly pivoting the saw like a hinge until the blade cuts through and the foot rests flat on the work. Then saw ahead on the line of cut line. We do not recommend plunge cutting with a scroll blade (Fig. 13).

To make sharp corners, cut up to the corner, then back up slightly before rounding the

WARNING

To prevent damage to the

extra certain that you move the saw along slowly. Use lower speeds. Do not twist, bend, or force the blade. If the saw jumps or bounces, use a blade with finer teeth. If the blade seems clogged when cutting soft metal, use a blade with coarser teeth.

For easier cutting, lubricate the blade with a stick of cutting wax, if available, or cutting oil when cutting steel. Thin metal should be

sandwiched between two pieces of wood or tightly clamped on a single piece of wood (wood on top of the metal). Draw the cut lines or design on the top piece of wood.

When cutting aluminum extrusion or angle iron, clamp the work in a bench vise and saw close to the vise jaws.

When sawing tubing and the diameter is larger than the blade is deep, cut through the wall of the tubing and then insert the blade into the cut rotating the tube as you saw.

This accessory is available at an extra cost. It is used for fast and accurate straight and circle cutting (Fig. 15).

ATTACHING RIP FENCE

1. Insert bar of rip fence through the slots provided in foot, from either side of foot with the edge guide facing down (Fig. 15).

2. Thread the clamp screw from under the foot through the threaded hole in the clamp on left side of foot, and securely tighten clamp screw with a screwdriver, to clamp the rip fence bar in place.
