GENERAL SAFETY RULES GEA002-1
WARNING:
Read all instructions. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious injury. The term
“power tool” in all of the warnings listed below refers to your mainsoperated (corded) power tool or battery-operated (cordless) power
tool.
SAVE THESE INSTRUCTIONS
Work area safety
1. Keep work area clean and well lit. Cluttered
and dark areas invite accidents.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
2
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust
or fumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
Electrical safety
4. Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
5. Avoid body contact with earthed or
grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an
increased risk of electric shock if your body is
earthed or grounded.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. 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.
8. When operating a power tool outdoors,
use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor
use reduces the risk of electric shock.
Personal safety
9. Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use a power tool while
you are tired or under the influence of
drugs, alcohol or medication. A moment of
inattention while operating power tools may
result in serious personal injury.
10. Use safety equipment. Always wear eye
protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions will reduce personal injuries.
11. Avoid accidental starting. Ensure the
switch is in the off-position before plugging in. Carrying power tools with your finger
on the switch or plugging in power tools that
have the switch on invites accidents.
12. Remove any adjusting key or wrench
before turning the power tool on. A wrench
or a key left attached to a rotating part of the
power tool may result in personal injury.
13. Do not overreach. Keep proper footing
and balance at all times. This enables bet-
ter control of the power tool in unexpected situations.
14. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing,
and gloves away from moving parts.
Loose clothes, jewellery or long hair can be
caught in moving parts.
15. If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of these devices can reduce dust-
related hazards.
Power tool use and care
16. Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the job better and
safer at the rate for which it was designed.
17. Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch is
dangerous and must be repaired.
18. Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety mea-
sures reduce the risk of starting the power
tool accidentally.
19. Store idle power tools out of the reach of
children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained
users.
20. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that
may affect the power tools operation. If
damaged, have the power tool repaired
3
before use. Many accidents are caused by
poorly maintained power tools.
21. Keep cutting tools sharp and clean. Prop-
erly maintained cutting tools with sharp cutting edges are less likely to bind and are
easier to control.
22. Use the power tool, accessories and tool
bits etc. in accordance with these instructions and in the manner intended for the
particular type of power tool, taking into
account the working conditions and the
work to be performed. Use of the power tool
for operations different from those intended
could result in a hazardous situation.
Battery tool use and care
23. Ensure the switch is in the off position
before inserting battery pack. Inserting the
battery pack into power tools that have the
switch on invites accidents.
24. Recharge only with the charger specified
by the manufacturer. A charger that is suit-
able for one type of battery pack may create a
risk of fire when used with another battery
pack.
25. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
fire.
26. When battery pack is not in use, keep it
away from other metal objects like paper
clips, coins, keys, nails, screws, or other
small metal objects that can make a connection from one terminal to another.
Shorting the battery terminals together may
cause burns or a fire.
27. Under abusive conditions, liquid may be
ejected from the battery, avoid contact. If
contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
Service
28. 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.
- WARNING- To reduce the risk of injury, user must read instruction manual.
ADDITIONAL SAFETY RULES FOR POWER
TOOL
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to drill safety rules. If
you use this power tool unsafely or incorrectly, you can suffer
serious personal injury.
1. Hold power tools by insulated gripping
surfaces when performing an operation
where the cutting tool may contact hidden
wiring or its own cord. Contact with a “live”
wire will make exposed metal parts of the tool
“live” and shock the operator.
