OPERATING INSTRUCTIONS

BEVEL ADJUSTMENT

TURN OFF AND UNPLUG TOOL. To adjust the bevel angle, loosen the screw (approximately 3 full turns) on the bottom of the shoe, as shown in Figure

2.Lift the shoe slightly and pull backward, then set the shoe at 45° and retighten screw. To reset the shoe for a square cut, loosen the screw and move the shoe until it is approximately 90° to the blade. Adjust the blade support roller to the blade and retighten the screw.

GENERAL CUTTING

Be sure board is firmly secured. Hold jig saw by the handle and operate switch to turn the unit on. Don’t attempt to turn on the unit when blade is against material to be cut. This could stall the motor. Place front of shoe on material to be cut and hold jig saw shoe down firmly against the work surface while cutting. Don’t force the tool; let the blade cut at its own speed. Whenever possible, clamp or support work close to the line of cut; when the cut is completed, shut off power and lay the saw aside before loosening the work.

CUT LINE BLOWER

To aid visibility when cutting, your jig saw is equipped with a cut line blower (Fig. 3) which will keep the work area clear of dust as you saw.

BLADE STORAGE

A convenient blade storage compartment (Fig. 3) is provided at the rear of the saw.

METAL & PLASTIC CUTTING

In cutting thin gauge sheet metals, it is best to clamp wood or plywood to the bottom of the metal sheet; this will insure a clean cut without the danger of vibration or tearing of metal. Use a fine- tooth blade for ferrous metals (for those that have an iron content); and use a coarser blade for nonferrous metals (those that do not have an iron content). Cutting thin metal will take longer than

cutting relatively thick wood so do not be tempted to speed up the process by forcing the saw. Spread a thin film of cutting lubricant along the cutting line (any light weight oil).

Use low speeds for cutting metals, plastics and composition tile. When cutting laminated plastic, place the finished side down and use a fine tooth hollow ground blade.

POCKET CUTTING

Measure the surface to be cut and mark clearly with a pencil. Next tip the saw forward until the front edge of the shoe sits firmly on the work surface, but with the blade well clear of it Figure 4.

Turn the tool on and allow it to attain maximum speed by fully depressing the trigger switch.

Grip the handle firmly and slowly lower the back edge of tool until the blade cuts smoothly into material. Do not move the jig saw forward along the cut line until the saw blade has completely entered the material and shoe comes to rest flat on its sur- face.

RIP & CIRCLE CUTTING Ripping and circle cutting without a pencil line are easily done with the rip fence and circle guide (available at extra cost).
