DUAL SPEED SELECTOR SWITCH

& TRIGGER LOCK

The stroke speed setting of the power tool can be changed with the stroke speed selector switch. However, this is not possible when the On/Off switch is pressed.

Stroke speed selector switch – central position:

The safety lock is activated.

The On/Off switch is blocked and the machine is secured against being switched on unintentionally.

Stroke speed selector switch – left:

1. Low stroke speed.

The low stroke speed is suitable for sawing hard materials such as steel, non-ferrous metal, hard

plastics or for precision cuts in wood and plunge cutting.

The low stroke speed enables sawing with less vibrations.

Stroke speed selector switch – right:

2. High stroke speed.

The high stroke speed is suitable for sawing soft materials.

The high stroke speed enables quicker operational progress, e. g., for coarse cuts in wood.

Using the Saw

1.Securely clamp the work.

2.Mark the line of cut and grasp the tool with one hand on the handle and the other placed on the insulated rubber boot over the front housing.

!WARNING Always operate the saw with the insulated boot on

the front housing. If you saw into a blind area where live wiring exists, you may be shocked or electrocuted.

3.Keep the saw footplate firmly against the work to minimize counter-force (jumping) and vibration.

4.Squeeze the trigger to start the tool. Let the saw reach full speed before starting the cut. Guide the saw so that the blade will move along the marked line.

SAWING TIPS

Following a few simple tips will reduce the wear on the workpiece, the tool and the operator.

1.Blades cut on the draw or back stroke. On fine work, such as paneling, fiberglass, etc., place the good side of workpiece facing down.

2.Use the correct saw blade for the material being cut and keep extra blades on hand to use when others become dull. Replace cracked or bent blades immediately.

3.Select the footplate projection settings, as well as the appropriate cutting speed.

4.To reduce the risk of injury, be sure the blade always extends beyond the footplate and work throughout the stroke. Blades may shatter if the front on the blade hits the work and/or the footplate.

WRONGRIGHT

5.When cutting metal:

-Apply a lubricant for easier, smoother, faster cutting and longer blade life.

-For non-ferrous metals, aluminum, bronze or brass, use a stick wax on the blade.

-For ferrous metals, iron and steel, use machine or cutting oil along the surface to be cut.

6.When cutting thin metal, "sandwich" the material between two pieces of scrap wood. Clamp or put in a bench vise. One piece of lumber on top of the metal can be used with adequate clamping. Place your cut lines or design on the wood.

7.Don’t force the cutting. Let the saw and blade do the work.
