Instruction & User Manual
Read all safety warnings, instructions and
specifications provided with this power
tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious
injury. Save all warnings and instructions for
future reference.
WARNING!
The term “power tool” in the warnings refers to
your mains operated (corded) power tool or battery
operated (cordless) power tool.
1. Work area safety
m Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
m 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.
m Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2. Electrical safety
m 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.
m 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.
m Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
m Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the power tool. Keep the cord away from
heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of
electric shock.
m 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.
m 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
m 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.
m Use personal protective equipment.
Always wear eye protection. Protective
equipment such as a dust mask, non-skid safety
shoes, hard hat or hearing protection used for
appropriate conditions will reduce personal
injuries.
m 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.
GENERAL POWER TOOL SAFETY WARNINGS
Page 5

JCB-RH850
Instruction & User Manual
m 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.
m Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in unexpected
situations.
m Dress properly. Do not wear loose
clothing or jewellery. Keep your hair and
clothing away from moving parts. Loose
clothes, jewellery or long hair can be caught in
moving parts.
m 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.
m Do not let familiarity gained from
frequent use of tools allow you to become
complacent and ignore tool safety
principles. A careless action can cause severe
injury within a fraction of a second.
4. Power tool use and care
m 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.
m 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.
m Disconnect the plug from the power
source and/or remove the battery pack,
if detachable, 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.
m 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.
m Maintain power tools and accessories.
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.
m Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier
to control.
m 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.
m Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not
allow for safe handling and control of the tool in
unexpected situations.
5. Service
m 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.

TOOL SPECIFIC SAFETY WARNINGS
1. Safety instructions for all operations
m Wear ear protectors when impact
drilling. Exposure to noise can cause
hearing loss.
m Use the auxiliary handle(s). Loss of
control can cause personal injury.
m Hold the power tool by insulated
gripping surfaces, when performing
an operation where the cutting
accessory or fasteners may contact
hidden wiring. Cutting accessory
contacting a “live” wire may make exposed
metal parts of the power tool “live” and
could give the operator an electric shock.
2. Safety instructions when using drill
bits
m Never operate at higher speed than
the maximum speed rating of the
drill bit. At higher speeds, the bit is likely
to bend if allowed to rotate freely without
contacting the workpiece, resulting in
personal injury.
m Use a detector to locate lines in walls
with concealed electric, water or gas
lines. Avoid touching live components
or conductors. Inadvertant contact with
hidden items may cause serious injury or
damage to the tool.
m Always start drilling at low speed
and with the bit tip in contact with
the workpiece. At higher speeds, the bit
is likely to bend if allowed to rotate freely
without contacting the workpiece, resulting
in personal injury.
m Apply pressure only in direct line with
the bit and do not apply excessive
pressure. Bits can bend causing breakage
or loss of control, resulting in personal
injury.
3. Safety instructions when using
hammer mode
m Keep exposure to vibrations as short
as possible. When carrying out work,
always hold the hammer with both
hands and ensure that you have a
stable standing position.Vibrations can
injure the nerves in hands & arms.
