Selecting the Speed Range

The speed control dial controls the maximum strokes per minute. The speed will remain variable to the chosen dial setting by use of the trigger switch. Refer to the chart for recommended dial settings.

Trigger Speed Control Switch

Super Sawzalls® are equipped with a trigger speed control switch. It may be operated at any speed from zero strokes per minute to full speed. Always start tool before blade contacts the workpiece. To vary the speed, simply increase or decrease the pressure on the trigger. The further the trigger is pulled, the greater the speed. To stop the tool, release the trigger and allow the tool to stop completely before removing from a partial cut or before laying the tool down.

General Cutting

For straight or contour cutting from an edge, line the blade up with your cutting line. Before the blade contacts the workpiece, grasp the handle firmly and pull the trigger. Then guide the tool along your cutting line. Always hold the shoe flat against the workpiece to avoid excessive vibration.

Cutting Metals

Begin cutting at a slow speed, gradually increasing speed as you cut. When cutting into metals or hard materials that can not be cut from an edge, drill a starting hole larger than the widest part of the blade. Extend blade life by using a solid blade cutting lubricant such as MILWAUKEE Band Saw Blade Lubricant Cat. No. 49-08-4206.

Plunge Cutting (Fig. 6)

Your MILWAUKEE Sawzall® is ideal for plunge cutting directly into sur- faces that can not be cut from an edge, such as walls or floors. Orbital action is recommended for plunge cutting. Plunge cutting may be done two ways depending on how the blade is inserted. Column A shows how to plunge cut with the teeth of the blade facing down. Column B shows how to plunge cut with the teeth of the blade facing up.

NOTE: Orbital action will not operate if the blade is installed with the teeth facing upward.

Do not plunge cut into metal surfaces (see “Cutting Metals”).

Fig. 6

1.Insert the blade into the tool.

If you inserted the blade with the teeth facing downward, hold the tool as shown in Column A, resting the edge of the shoe on the workpiece.

If you inserted the blade with the teeth facing upward, hold the tool as shown in Column B, resting the edge of the shoe on the workpiece as shown.

2.With the blade just above the workpiece, pull the trigger. Using the edge of the shoe as a pivot, lower the blade into the workpiece as shown.

3.As the blade starts cutting, raise the handle of the tool slowly until the shoe rests firmly on the workpiece. Then guide the tool along your cutting line to acquire the desired cut.

NOTE: To make plunge cutting easier, use a heavy gauge blade and install the blade with the teeth facing upward as shown in Column B.

WARNING!

To reduce the risk of explosion, electric shock and property damage, always check the work area for hidden gas pipes, electrical wires or water pipes when making blind or plunge cuts.
