18. Outdoor use extension cords

When tool is used outdoors, use only extension

cords intended for use outdoors and so marked.

19. Stay alert

Watch what you are doing. Use common sense. Do

not operate tool when you are tired.

20. Check damaged parts

Before further use of the tool, a guard or other part

that is damaged should be carefully checked to

determine that it will operate properly and perform

its intended function. Check for alignment of moving

parts, binding of moving parts, breakage of parts,

mounting, and any other conditions that may affect

its operation. A guard or other part that is damaged

should be properly repaired or replaced by an autho-

rized service center unless otherwise indicated else-

where in this instruction manual. Have defective

switches replaced by and authorized service center.

Do not use tool if switch does not turn it on and off.

21. Warning

The use of any other accessory or attachment other

than recommended in this operating instruction or

the catalog may present a risk of personal injury.

22. Have your tool repaired by an expert

This electric appliance is in accordance with the rel-

evant safety rules. Repairing of electric appliances

may be carried out only by experts otherwise it may

cause considerable danger for the user.

ADDITIONAL SAFETY RULES

ENB009-1

1. Hold tools by insulated gripping surfaces when

performing an operation where the cutting tool

may contact hidden wiring or its own cord. Con-

tact with a “live” wire will make exposed metal

parts of the tool “live” and shock the operator.

2. Wear ear protectors when using the tool for

extended periods. Prolonged exposure to high

intensity noise can cause hearing loss.

3. Wear a hard hat (safety helmet), safety glasses

and/or face shield. It is also highly recom-

mended that you wear a dust mask and thickly

padded gloves.

4. Be sure the bit is secured in place before opera-

tion.

5. Under normal operation, the tool is designed to

produce vibration. The screws can come loose

easily, causing a breakdown or accident. Check

tightness of screws carefully before operation.

6. In cold weather or when the tool has not been

used for a long time, let the tool warm up for a

while by operating it under no load. This will

loosen up the lubrication. Without proper warm-

up, hammering operation is difficult.

7. Always be sure you have a firm footing.

8. Be sure no one is below when using the tool in

high locations.

9. Hold the tool firmly with both hands.

10. Keep hands away from moving parts.

11. Do not leave the tool running. Operate the tool

only when hand-held.

12. Do not point the tool at any one in the area when

operating. The bit could fly out and injure some-

one seriously.

13. Do not touch the bit or parts close to the bit

immediately after operation; they may be

extremely hot and could burn your skin.

SAVE THESE INSTRUCTIONS.

OPERATING INSTRUCTIONS

Installing or removing the bit (Fig. 1)

CAUTION:

Always be sure that the tool is switched off and

unplugged before installing or removing the bit.

With the notched portion on the shank of the bit facing

toward the tool retainer, insert the bit into the tool holder

as far as it will go. Then pull out and turn the tool retainer

180° to secure the bit. After installing, always make sure

that the bit is securely held in place by trying to pull it out.

Side handle (auxiliary handle) (Fig. 2)

The side handle can be either freely swiveled or secured

at one position for use during tool operation. Just loosen

the nut to swivel the handle freely.

To secure the handle at a fixed position, first loosen the

nut and swing the handle to the desired position for use.

Then tighten the nut firmly. If the set bolt turns together

with the nut when you secure the nut, see that the pro-

jecting portion of the side handle fits into the notch on the

head of the set bolt.

Switch action (Fig. 3)

CAUTION:

• Before plugging in the tool, always check to see that

the switch trigger actuates properly and returns to the

“OFF” position when released.

• Switch can be locked in “ON” position for ease of oper-

ator comfort during extended use. Apply caution when

locking tool in “ON” position and maintain firm grasp on

tool.

To start the tool, simply pull the switch trigger. Release

the switch trigger to stop. For continuous operation, pull

the switch trigger and then slide down the lock button. To

stop the tool from the locked position, pull the switch trig-

ger fully, then release it.

Chipping / Scaling / Demolition (Fig. 4)

Hold the tool firmly with both hands. Turn the tool on and

apply slight pressure on the tool so that the tool will not

bounce around, uncontrolled. Pressing very hard on the

tool will not increase the efficiency.
