Warnings

WARNING Read all safety warnings and all

instructions. Failure to follow the warnings and

instructions may result in electric shock, fire and/or

serious injury.

Save all warnings and instructions for

future reference.

GEB004-6

HAMMER SAFETY WARNINGS

1. Wear ear protectors. Exposure to noise can

cause hearing loss.

2. Use auxiliary handle(s), if supplied with the

tool. Loss of control can cause personal injury.

3. Hold power tool by insulated gripping

surfaces, when performing an operation

where the cutting accessory may contact

hidden wiring or its own cord. Cutting

accessory contacting a "live" wire may make

exposed metal parts of the power tool "live" and

could give the operator an electric shock.

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

and/or face shield. Ordinary eye or sun

glasses are NOT safety glasses. It is also

highly recommended that you wear a dust

mask and thickly padded gloves.

5. Be sure the bit is secured in place before

operation.

6. 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.

7. 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.

8. Always be sure you have a firm footing.

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 someone 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.

14. Do not operate the tool at no-load

unnecessarily.

15. Some material contains chemicals which may

be toxic. Take caution to prevent dust

inhalation and skin contact. Follow material

supplier safety data.

SAVE THESE INSTRUCTIONS.

WARNING:

DO NOT let comfort or familiarity with product

(gained from repeated use) replace strict adherence

to safety rules for the subject product.

MISUSE or failure to follow the safety rules stated in

this instruction manual may cause serious personal

injury.
