OPERATING PROCEDURES

SPEED ADJUST

This tool has a variable speed switch that delivers higher speed with

increased trigger pressure.

Speed is controlled by the amount of trigger switch depression.

SHOE ADJUSTMENT

The shoe of your reciprocating saw pivots. The shoe is also adjustable,

allowing the use of the blade teeth at different positions on the blade.

1. Unplug your saw.

WARNING: Failure to unplug your saw could result in accidental

starting causing serious injury.

2. Loosen both the cap screws in the gear frame with hex key.

3. Reposition shoe assembly in or out.

4. Retighten both cap screws securely. Do not over tighten cap

screws.

5. Remove hex key.

WARNING: Cutting into electrical wiring in walls can cause blade,

clamp, and saw bar assembly to become electrically charged. Do

not touch metal parts when cutting into a wall; grasp only the

insulated gripping surfaces provided by the tool. Make sure hidden

electrical wiring, water pipes, and mechanical hazards are not in the

blade path when cutting into a wall.

TYPES OF CUTTING

NOTE: Make sure that you do not hit any electrical wires, gas or water pipes.

Check the wall with a pipe/cable detector before you begin cutting.

GENERAL CUTTING

Clamp your workpiece if it is portable, rest the front shoe of the saw

on your workpiece (be sure the blade is not contacting the workpiece)

and start the saw, exerting enough pressure in the direction of the cut

to keep the shoe pressed firmly against the work piece at all times,

Do not force the cut or stall the saw. Don't bend or twist the blade, let

the tool and the blade do the work.

In general, coarser blades are for wood, plastics , and composites ,

and finer blades are for cutting metal, chattering or vibration may

indicate you need fine blade or higher speed, if the blade overheats or

clogs, it may indicate you need a coarser blade when they become

dull, dull blades will produce poor results and may overheat the saw.

PLUNGE CUTTING

Clearly mark the line of cut, from a convenient starting point within the

cut out area, place the tip of the blade over that point with saw parallel

to the line of cut, slowly lower the saw until the bottom edge of the

shoe rests on the workpiece and the blade is not touching the work-

piece, start the saw and allow it to attain full speed. With the saw

resting on the shoe, slowly tilt the saw forward to lower the blade onto

the cut line. Continue this motion until the saw blade is perpendicular

to the workpiece.

METAL CUTTING

Blades specifically designated for cutting metals must be used for this

purpose. You may use light oil as a coolant when cutting metal, this

will prevent overheating of the blade, help the blade cut faster, and

promote longer blade life.
