ELECTRICAL SAFETY cont.
3. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
4. Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
5. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of electric shock.
6. When operating a power tool outdoors, use an extension cord suitable for outdoor
use marked "W-A" or "W". Use of a cord suitable for outdoor use reduces the risk of
electric shock.
7. If operating a power tool in a damp location is unavoidable, use a Ground Fault
Circuit Interupter (GFCI) protected supply. Use of a GFCI reduces the risk of
electric shock.
EXTENSION CORDS
USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage
number, the heavier the cord.

CAUTION:
Keep the extension cord clear of the working area. Position
!
the cord so that it will not get caught on lumber, tools or other obstructions while
you are working with a power tool.
WARNING:
Check extension cords before each use. If damaged replace
!
immediately. Never use tool with a damaged cord since touching the damaged
area could cause electrical shock, resulting in serious injury.

SERVICE SAFETY
1. If any part of this tool is missing or should break, bend, or fail in any way;
or should any electrical component fail to perform properly: SHUT OFF the power
switch and remove the saw's plug from the power source and have the missing,
damaged or failed parts replaced BEFORE resuming operation.
2. Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
3. If the replacement of the supply cord is necessary, this has to be done by the
manufacturer or his agent in order to avoid a safety hazard.

SAFETY RULES FOR HAMMER DRILLS
1. Know your Professional Hammer Drill. Read operator's manual carefully. Learn
its applications and limitations, as well as the specific potential hazards related
to this tool. Following this rule will reduce the risk of electric shock, fire, or
16
14
serious injury.

2. BE SURE that twist drill bits, drive bits, hammer drill bits and other accessory
14

attachments are properly and securely mounted in the chuck jaws BEFORE
operating the hammer drill.
Not recommended
3. ALWAYS carefully inspect the material you are going to drill into. Drilling into nails,
pipes and electrical wires can cause serious personal injury.
4. HOLD HAMMER DRILL by insulated gripping surfaces (handles) when performing
an operation where the tool may drill into hidden wiring. Contact with a "live" wire
will make the exposed metal parts of the tool "live" and shock the operator.
5. NEVER hold the piece being drilled in your hands or across your legs. It is
important to support and clamp the workpiece properly in order to minimize body
exposure, bit binding, or loss of control.
It means attention! Your safety is involved.
