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 mains-operated (corded)
power tool or battery-operated (cordless)
power tool.
Work area safety
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gasses 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.
9. 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.
10.Use of power supply via a RCD with a
rated residual current of 30Ma or less
is always recommended.
Personal safety
11.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.
12.Use personal protective equipment.
Always wear eye protection. Protective
equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing

-1- -2-
protection used for appropriate
conditions will reduce personal injuries.
13.Prevent unintentional starting. Ensure
the switch is in the off- position before
connecting to power source and/or
battery pack, picking up pr carrying the
tool. Carrying power tools with your
finger on the switch or energizing power
tools that have the switch on invites
accidents.
14.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.
15.Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in
unexpected situations.
16.Dress properly. Do not wear loose
clothing or jewelry. Keep your hair,
clothing, and gloves away from moving
parts. Loose clothes, jewelry or long hair
can be caught in moving parts.
17.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-related
hazards.
Power tool use and care
18.Do not force the power tool. Use the
correct power tool for your application.
The correct power tool will do the job
better and more safely at the rate for
which it was designed.
19.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.
20.Disconnect the plug from the power
source and/or the battery pack from
the power tool before making and
adjustments, changing accessories, or
storing power tools. Such preventive
safety measures reduce the risk of
starting the power tool accidentally.
21.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.
22.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.
23.Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
24.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.
Service
25.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.
26.Follow instruction for lubricating and

changing accessories.
27.Keep handles dry, clean and free from
oil and grease.
HAMMER SAFETY
WARNINGS
1. Wear ear protectors. Exposure to
noise can cause hearing loss.
2. Use auxiliary handle(s), if supplied
with the tool. Loss of control can
cause personal injury.
3. Hold power tool by insulated gripping
surfaces, when performing an
operation where the cutting accessory
may contact hidden wiring or its own
cord. Cutting accessory contacting a
“live” wire may make exposed metal
parts of the power tool “live” and
could give the operator an electric
shock.
4. Wear a hard hat (safety helmet), safety
glasses and/or face shield. Ordinary
eye or sun glasses are NOT safety
glasses. It is also highly recommended
that you wear a dust mask and thickly
padded gloves.
5. Be sure the bit is secured in place
before operation.
6. Under normal operation, the tool is
designed to produce vibration. The
screws can come loose easily, causing
a breakdown or accident. Check
tightness of screws carefully before
operation.
7. In cold weather or when the tool has
not been used for a long time, let the
tool warm up for a while by operating
it under no load. This will loosen
up the lubrication. Without proper
warm-up, hammering operation is
difficult.
8. Always be sure you have a firm
footing. Be sure no one is below when
using the tool in high locations.
9. Hold the tool firmly with both hands.
10.Keep hands away from moving parts.
11.Do not leave the tool running. Operate
the tool only when hand-held.
12.Do not use the tool to point at any
one in the area when operating. The
bit could fly out and injure someone
seriously.
13.Do not touch the bit or parts close to
the bit immediately after operation;
they may be extremely hot and could
burn your skin.
14.Do not operate the tool at no-load
unnecessarily.
15.Some material contains chemicals
which may be toxic. Take caution
to prevent dust inhalation and skin
contact. Follow material supplier
safety data.

Replacing carbon brushes
When the resin insulating tip inside
the carbon brush is exposed to contact the
commutator, it will automatically shut off
the motor. When this occurs, both carbon
brushes should be replaced. Keep the
carbon brushes clean and free to slip in
the holders. Both carbon brushes should
be replaced at the same time. Use only
identical carbon brushes.
Use a hex wrench to remove the rear
cover.
Use a screwdriver to remove the brush
holder caps. Take out the worn carbon
brushes, insert the new ones and secure the
brush holder caps.
This tool requires no hourly or dairy
lubrication because it has a grease-packed
lubrication system. It should be relubricated
after every 6 months of operation. Send
the complete tool to DOXS Authorized of
Factory Service Center for this lubrication
service. However, if circumstances require
that you should lubricate it by yourself,
proceed as follows.
Run the tool for several minutes to
warm it up. Switch off and unplug the tool.
Remove the crank cap using a DOXS
lock nut wrench 35(optional accessory).
Rest the tool on the table with the bit end
pointing upwards. This will allow the old
grease to collect inside the crank housing.
