14. Maintain tools with care
Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating
and changing accessories. Inspect tool cords
periodically and, if damaged, have repaired by
authorized service facility. Inspect extension
cords periodically and replace if damaged. Keep
handles dry, clean and free from oil and grease.
15. Disconnect tools
When not in use, before servicing, and when
changing accessories such as blades, bits and
cutters.
16. Remove adjusting keys and wrenches
Form the habit of checking to see that keys and
adjusting wrenches are removed from tool before
turning it on.
17. Avoid unintentional starting
Don't carry plugged-in tool with finger on switch.
Be sure switch is off when plugging in.
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 per-
form 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 authorized service center unless
otherwise indicated elsewhere 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
relevant safety rules. Repairing of electric appli-
ances may be carried out only by experts other-
wise it may cause considerable danger for the
user.

ADDITIONAL SAFETY RULES

1. Wear a hard hat (safety helmet), safety
glasses and/or face shield. It is also highly
recommended that you wear a dust mask, ear
protectors and thickly padded gloves.
2. Be sure the bit is secured in place before
operation.
3. Under normal operation, the tool is designed
to produce vibration. The screws can come
loose easily, causing a breakdown or acci-
dent. Check tightness of screws carefully
before operation.
4. In cold weather or when the tool has not been
used for a long time, let the tool warm up for
several minutes by operating it under no
load. This will loosen up the lubrication.
Without proper warm-up, hammering opera-
tion is difficult.
5. Always be sure you have a firm footing. Be
sure no one is bellow when using the tool in
high locations.
6. Hold the tool firmly with both hands.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the
tool only when hand-held.
9. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
10. When drilling or chipping into walls, floors or
wherever "live" electrical wires may be
encountered, DO NOT TOUCH ANY METAL
PARTS OF THE TOOL! Hold the tool by the
insulated grasping surfaces to prevent elec-
tric shock if you drill or chip into a "live" wire.
11. 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.

After installing, always make sure that the bit is
securely held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the
way and pull the bit out. (Fig. 4)
