5. HEALTH AND SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
Warning! Read all safety warnings, instructions, illustrations 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.
The term “power tools” in the warnings refers to your mains-operated (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 earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) 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.
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 a dust mask, non-skid safety shoes, hard hat or hearing protection use 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.
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 and clothing
away from moving parts. Loose clothes, jewellery or long hair can be caught in moving
– 6 –

5. HEALTH AND SAFETY INFORMATION
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.
h) 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
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 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.
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 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.
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.
h) 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
a) Have your power tool serviced by a qualified repair person using only identical
replacements parts. This will ensure that the safety of the power tool is maintained.

– 8 –

5. HEALTH AND SAFETY INFORMATION
If the cover is missing, a replacement must be obtained or the plug replaced with a suitable type.
If a replacement plug is to be fitted this must be carried out by a qualified electrician.
Never use a damaged or incomplete plug.
This appliance is Class II†and is designed for connection to a power supply matching that
detailed on the rating label and compatible with the plug fitted.
Carefully select an extension lead. Some machines are not suitable for use with extension
leads. If the tool is designed for use outdoors, only use an extension lead suitable for that
environment in conjunction with an RCD adaptor. When using an extension lead, select one
capable of handling the current (amps) drawn by the machine in use. Ensure the cable is fully
unwound regardless of the distance between the power supply and the tool. Excess current
(amps) and a coiled extension lead will cause the cable to heat up and can result in fire.
Keep extension leads away from moving hazardous parts to avoid damages to the cable
which can lead to contact with live parts. Position cable safely to avoid tripping over.
†Double insulated : This product requires no earth connection as supplementary insulation is
applied to the basic insulation to protect against electric shock in the event of failure of the
basic insulation.
Important! If using an extension lead, follow the instructions that came with your lead
regarding maximum load while cable is wound. If in doubt, ensure that the entire cable is
unwound. Using a coiled extension lead will generate heat which could melt the lead and
cause a fire.
5.4 RESIDUAL RISK
Important: Although the safety instructions and operating manuals for our tools contain
extensive instructions of safe working with power tools, every power tool involves a certain
residual risk which can not be completely excluded by safety mechanisms. Power tools must
therefore always be operated with caution!

or Stock No. 22231 EOBD 16pin diagnostic
socket type (Fig.2) before disconnecting the
battery. Check that the voltage of the battery
matches that of the charger. 1FIG.
2FIG.

9.1 APPLICATION
The charger is designed for charging non maintenance-free or maintenance-free 12V lead acid
batteries (wet / Ca/Ca / EFB batteries) and for lead gel and AGM batteries which are used in
motor vehicles.
9.2 CONNECTION
Before you connect the equipment to the power supply make sure that the data on the
specifications label are identical to the supply voltage.
Warning! Do not charge any frozen batteries.
Please also refer to the instructions in the owner’s manuals for the car, radio, navigation
system, etc.
Notes on automatic charging (programs 12V STD, 12V AGM/C, 12V GEL, 12V LFP)
The charger is a microprocessor controlled automatic charger, i.e. it is suitable in particular for
charging maintenance-free batteries and for the long-term charging and maintenance-charging
of batteries which are not in constant use, e.g. for classic cars, recreational vehicles, lawn
tractors and the like. The integrated microprocessor enables charging in several steps. The
final charging step, maintenance charging, maintains the battery capacity at 95–100% and
therefore keeps the battery fully charged at all times. The charging operation does not need to
be monitored. However, do not leave the battery unattended if you charge it over an extended
period of time, so that you can disconnect it from the mains power supply in the event of a
fault in the charger.
9.3 PERMANENT INSTALLATION
OF “O”RINGS TO BATTERY – FIG. 3
The permanently installed “O” rings M8 allow
the battery to be connected to charger via
connector without obtaining access to battery.
(chiefly for motorbikes, classic cars, jetski’s etc
where access to battery is difficult).
9.4 SETTING THE CHARGING PROGRAMS
• If the voltage of the battery is less than 3.5V or more than 15V, the battery is either not
suitable for charging or it is faulty. The message “BAt” will appear in the LCD display. The
symbol will flash. It is also possible that other battery errors or faults can mean that the
battery cannot be charged.
• If there is a short-circuit between the charging terminals while the SUPPLY function is on,
the message “Lo V” will appear in the LCD display. The symbol will flash.
• When the charger is disconnected from the socket outlet, the last charging program to
have been set will be saved (apart from 6V STD and SUPPLY) and will be the default
program the next time the charger is used.

With a battery connected to vehicle:
Note: All loads in the vehicle must be switched off during charging.
a. Connect the RED positive charger lead to the positive (+) terminal on your battery.
b. Connect the BLACK negative charger lead to your vehicles ground connection on
either the engine or chassis, away from any fuel lines or the battery vents.
If the clamps are INCORRECTLY connected with regard to polarity, the LCD screen will
display the following (the + and - inside the battery icon, the fault icon and “Err”), and a
warning will sound until the clamps are disconnected. Unplug the charger, then remove the
clamps, reconnect the clamps properly.
Warning! Under normal circumstances the negative battery pole is connected to the bodywork
and you proceed as described above. In exceptional cases (refer to the manufacturers manual)
it is be possible that the positive battery pole is connected to the bodywork (positive earthing).
In this case connect the black charger cable to the negative pole on the battery. Then connect
the red charger cable to the bodywork at a point away from the battery and the petrol pipe.
• After the battery has been connected to the charger, you can connect the charger to a
socket. You can now change the charging settings.
• Important! Charging may create dangerous explosive gas and therefore you should
avoid spark formation and naked flames whilst the battery is charging. There is a risk of
explosion! It is essential that you ventilate the rooms well.
• When “FUL” appears in the LCD display, charging has been completed. The charger holds
the battery at 95% – 100% available battery capacity using pulsed charging. If the charger
shows this after just a few minutes, this indicates that the battery capacity is low. The
battery needs replacing.
9.9 FAULT INDICATOR
The fault indicator will flash (light up) in the following cases:
• If the voltage of the battery is less than 3.5 V or more than 15 V. The battery is either
unsuitable for charging or is defective. It is also possible that other battery errors or faults
can mean that the battery cannot be charged.
• If the terminal clamps are connected to the battery terminals with the wrong polarity. The
protection against swapped poles ensures that the battery and charger do not get damaged.
Remove the charger from the battery and start the charging process from the beginning again.
Caution! Protection against swapped poles is not available when the SUPPLY program is used.
• If there is a short-circuit between the two terminal clamps (the metal parts of the clamps
come into contact with each other). The protection against short-circuits ensures that the
battery and charger do not get damaged.
9.10 FINISHING CHARGING THE BATTERY
• Pull the plug out of the socket.
• Disconnect the black charging cable from the bodywork.
• Then release the red charging cable from the positive pole on the battery.
• Important! In case of positive earthing, first disconnect the red charging cable from the
bodywork and then the black charging cable from the battery.
• Screw or push the battery stoppers back into position (if there are any).
Important! If the mains plug is pulled out but the charger cables are still connected to the
battery, the charger will draw off a small amount of electricity from the battery. We therefore
recommend that you always completely remove the charger from the battery when not in use.
