OPERATION

WARNING:

Do not allow familiarity with this product to make you

careless. Remember that a careless fraction of a second is

sufficient to inflict serious injury.

WARNING:

Always wear eye protection with side shields marked to

comply with ANSI Z87.1. Failure to do so could result in

objects being thrown into your eyes and other possible

serious injuries.

WARNING:

Do not use any attachments or accessories not recom-

mended by the manufacturer of this tool. The use of at-

tachments or accessories not recommended can result

in serious personal injury.

WARNING:

To avoid possible serious injury, keep hands and fingers

away from the area between the gear housing and saw

blade clamp.

APPLICATIONS

You may use the jig saw for the purposes listed below:

 Sawing non-ferrous metal, sheet steel, wood, plastic,

and similar materials.

SWITCH

See Figure 4, page 14.

To turn the saw ON, depress the trigger switch. Release

trigger switch to turn the saw OFF.

LOCK-ON BUTTON

See Figure 4, page 14.

The saw is equipped with a lock-on feature, which is conve-

nient when continuous cutting for extended periods of time

is required. To lock-on, depress the trigger switch, push

in and hold the lock-on button located on the side of the

handle, then release trigger switch. Release lock-on button

and your saw will continue running.

To release the lock, depress the trigger switch and release.

If you have the lock-on feature engaged during use and your

saw becomes disconnected from power supply, disengage

the lock-on feature immediately.

WARNING:

Before connecting the saw to power supply, always

check to be sure it is not in lock-on position (depress and

release trigger switch). Failure to comply could result in

accidental starting and possible serious injury. Also, do

not lock the trigger on jobs where the saw may need to

be stopped suddenly.

VARIABLE SPEED

See Figure 5, page 14.

The saw has a variable speed control selector designed to

allow operator control and adjustment of speed and power

limits. The speed and power of your saw can be increased

or decreased by rotating the variable speed control selector

in the direction of the arrows shown in figure 5.

NOTE: Hold the saw in normal operating position and turn

the variable speed control selector to the positive symbol

to increase speed and power. Turn to the negative symbol

to decrease speed and power.

If you desire to lock the switch on at a given speed, depress

the trigger switch, push in and hold the lock-on button, and

release the trigger switch. Next, adjust the variable speed

control selector until the desired speed is reached.

Avoid running your saw at low speeds for extended periods

of time. Running at low speeds under constant usage may

cause your saw to become overheated. If this occurs, cool

your saw by running it without a load and at full speed.

The following guidelines may be used in determining correct

speed for various applications:

LOW speed is ideal when minimum speed and power is

required, for example, starting cuts.

MEDIUM speed is suitable for cutting hard metals, plastics,

and laminates.

HIGH speed produces best results when maximum power

is required, for example, cutting wood. Soft metals such as

aluminum, brass, and copper may also require high speeds.

WARNING:

Do not insert saw blade into air vents. They could come

in contact with electrically live internal parts, and cause

electrical shock resulting in serious injury.
