GENERAL POWER TOOL SAFETY 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. The term "power tool" in
the warnings refers to your electric (corded)
power tool or battery-operated (cordless) power
tool.
1. Work area safety
a) Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or
fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
2. Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way. Do not use
any adapter plugs with grounded power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) 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.
e) 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.
f) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk
of electric shock.
3. Personal safety
a) 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.
b) Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
c) Prevent unintentional starting. Ensure the
switch is in the off position before connecting to
power source and/or battery pack, picking up or
carrying the tool. Carrying power tools with your
finger on the switch or energising power tools that
have the switch on invites accidents.
d) 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.

GENERAL POWER TOOL SAFETY WARNINGS
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
f) 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.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
4. Power tool use and care
a) 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.
b) 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.
c) 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 measures reduce the risk of
starting the power tool accidentally.
d) 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.
e) Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts and
any other condition that may affect the power
tool’s operation. If damaged, have the power tool
repaired before use. Many accidents are caused
by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits
etc. in accordance with these instructions, 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.
5. Service
a) 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.
b) If the replacement of the supply cord is
necessary, this has to be done by the
manufacturer or its agent in order to avoid a
safety hazard.

GENERAL POWER TOOL SAFETY WARNINGS
6. Safety Warnings for Rotary Hammer
a) Wear ear protectors with rotary hammers.
Exposureto noise can cause hearing loss.
b) Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
c) 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 ofthe tool “ live”
and shockthe operator.
d) Let bit cool before touching, changing or
adjusting it. Bits heat up dramatically while in
use, and can burn you.
e) If the drill bit jams, release the trigger
immediately; drill torque can cause injury or
break bit.
f) Maintainlabels and nameplates on the tool.
These carry important safety information. If
unreadable ormissing, Contact Lumberjack
Tools for a replacement.
g) Avoid unintentional starting. Prepare to
begin work before turning on the tool.
h) Do not lay the tool down until it has cometo
a complete stop. Moving parts can grab the
surface and pull the tool out ofyour control.
I) When using a handheld power tool, maintain
a firm grip on the tool with both hands to resist
starting torque.
J) Do not leave the tool unattended when it is
plugged into an electrical outlet. Turn off the
tool, and unplug it from its electrical outlet
before leaving.
k) This product isnot a toy. Keep it out of reach
of children.
l) People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity toheart pacemaker could cause
pacemaker interference or pacemaker failure. In
addition, people with pacemakers should:
●Avoid operating alone. ●Do not use with
power switch locked on.●Properly maintain
and inspect to avoid electrical shock. ●Any
power cord must be properly grounded. Ground
Fault Circuit Interrupter(GFCI) should also be
implemented – itprevents sustained electrical
shock.
7. Safety Warnings for Drill
a)When using the electric hammer chisel only use
bits that are configured with the correct slots for
this chuck.
b)BEFORE STARTING the operation, jog the chisel
switch to make sure the chisel bit does not wobble
or vibrate.
c)DO NOT USE fly cutters ormultiple-part hole
cutters, asthey can come apart or become
unbalanced inuse.
d)MAKE SURE the spindle hascome to a complete
stop before touching the chuck orattempting to
change the chisel bit also beware that the bit will
be hot, let it cool down before changing asitcould
burn and cause injury.
e)ALWAYS MAKE SURE THE CHISEL IS FIRMLY
SEATED INTHE HEX CHUCK before starting the job
inhand.

GENERAL POWER TOOL SAFETY WARNINGS
8. Safety Warnings for Vibration safety
This tool vibrates during use. Repeated or long-
term exposure to vibration may cause
temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration-related injury:
a) Wear suitable gloves toreduce the vibration
effects onthe user.
b) Use tools with the lowest vibration when
there is a choice.
c) Include vibration-free periods each day of
work.
d)To reduce vibration, maintain the tool as
explained in this manual. Ifany abnormal
vibration occurs, stop useimmediately.
9. Using an Extension Cable
.
a) If an extension cable is required, use an
approved triple core extension cable suitable for
the power input of the tool.
b) Grounded tools always require a three wire
extension cable.
c) As the distance from the supply outlet
increases you must use a heavier gauge extension
cable. Using extension cables with inadequately
sized wire causes a serious drop in voltage,
resulting in loss of power and possible tool
damage.
d) The smaller the gauge number of the wire the
greater the capacity of the cord.
e) When using a cable reel, always unwind the
cable completely.
