GENERAL SAFETY RULES
1. Always ensure when jump-starting that there is air circulating around the
machine.
2. Never allow the negative and positive leads on this unit, to touch each
other or to touch the same metal object.
3. Although the jump-start is water resistant and may be used outdoors, DO
NOT leave it exposed to the elements. Avoid direct sunlight, direct heat,
rain/moisture etc.
4. The JS910 jump-start is designed for use with 12V systems.
5. Do not operate the jump-start if any of the cables are damaged. Consult

ELECTRICAL CONNECTIONS
This product is provided with a 13 amp, 230 volt (50Hz), charging adaptor for
connection to a standard, domestic electrical supply. Should the plug need
changing at any time, ensure that a plug of identical specification is used.
This product is of double insulated design. No earth conductor is
provided.
No earth conductor is provided. The two wires in the mains lead should be
wired up in accordance with the following colour code:
Blue — Neutral
Brown — Live
Connect the BROWN coloured cable to the plug terminal marked a letter “L”.
Connect the BLUE coloured cable to the plug terminal marked a letter “N”.
If the battery charger for this appliance is fitted with a plug which is moulded
on to the electric cable (i.e. non-rewireable) please note:
1. The plug must be thrown away if it is cut from the electric cable. There is a
danger of electric shock if it is subsequently inserted into a socket outlet.
2. Never use the plug without the fuse cover fitted.
3. Should you wish to replace the fuse cover, ensure that the correct
replacement is used (as indicated by marking or colour code).
4. Replacement fuse covers can be obtained from your local Clarke dealer
or most electrical stockists.
FUSE RATING
The fuse in the plug must be replaced with one of the same rating and this
replacement must be ASTA approved to BS1362.
If in any doubt, consult a qualified electrician. DO NOT attempt any electrical
repairs yourself.

COMPONENT IDENTIFICATION
The JS900 & 910 is a rechargable power supply which can be used to start a
car in the event of a flat battery. The unit can also be used to power electrical
appliances via a cigarette lighter type socket using the adaptor supplied. The
unit also incorporates a built-in lamp and may be used as a stand alone light
source. An audible warning will sound in the event of low battery voltage, or if
the clamps are incorrectly fitted for jump starting (wrong polarity). The integral
The integral air compressor (JS910) is ideal for pumping up tyres on the vehicle.

INITIAL BATTERY CHARGING
1. Charge your jump-start battery before using it for the first time.
2. Recharge the jump-start battery after every occasion of use if possible,
and thereafter, at least every 30 days.
3. Always avoid leaving your jump-start in a discharged state.
FOLLOW THE ABOVE POINTS TO ENSURE MAXIMUM LIFE FROM THE BATTERY.
Two means of charging the battery are provided:
1. Via a 230V mains electricity
supply, using the mains adaptor,
as shown.
2. Via a 12V supply using the vehicle
cigar lighter adapter with cable
and plug provided.
NOTE: Using a 12V vehicle supply,
the battery will not charge to
maximum, but only to
approx. 50% of its capacity.
NOTE: A 5 amp fuse is fitted into the cigarette lighter plug adaptor,
accessed by unscrewing the end cap of the adaptor. Take care
not to loose the spring when unscrewing this cap.
CHARGING USING THE 230V MAINS ADAPTOR
1. Plug the cable into the socket in
the charger, then plug the
adaptor into the mains supply
and switch on.
• The red CHARGING light on the
jump-start will come on to
indicate charging is in progress.
2. Continue to charge until the RED
charging light goes out. It is
important to note that this could
take several days, dependant
upon the state of charge of the
battery.
• Pressing the ‘TEST’ button, with
the charger disconnected, will
REVERSE

8
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
cause the needle on the voltmeter to indicate the state of charge
of the battery.
• Once the charger is disconnected, it will be noted that the voltage
will slowly settle back. This is quite normal and should not cause
alarm. When the LED extinguishes, charging will automatically stop,
indicating that the battery is at maximum capacity.
IMPORTANT: DO NOT allow the needle to enter the RED zone as this could
damage the battery.
CHARGING USING THE 12V ADAPTOR
1. Plug the jack plug into the charging socket at the rear of the unit, then into
the cigar lighter socket on the vehicle and start the engine. The red LED on
the jump-start will indicate that charging is in progress.
2. Continue to charge until the “Internal Battery Status” gauge registers ‘OK’
when the ‘TEST’ button is pressed, WITH THE CHARGING CURRENT
DISCONNECTED. i.e. disconnect the cigar lighter adapter from the socket
on the vehicle before pressing the TEST switch.
NOTE: We recommend that you use this system only when necessary, as
prolonged use will reduce the life expectancy of the battery, due
to the fact that this method can only charge the battery to
approx. 50% of its capacity.
NOTE: For maximum battery life, we strongly recommend that you
maintain the battery in a fully charged state at all times.
NOTE: If charging does not take place, check the green LED on the
adapter. Ensure all connections are clean and free of grease etc.
OPERATION
Always carry out the following preliminary checks before connecting the
jump-start to the car battery:
• Ensure the vehicle ignition and ALL ancillary equipment - lighting,
radio etc, is switched off.
• Ensure the vehicle battery is rated at 12V and is not damaged in any
way.
WARNING: FAILURE TO FOLLOW THE INSTRUCTIONS BELOW AND THE
SAFETY INSTRUCTIONS ON PAGES 3/4, MAY RESULT IN PERSONAL INJURY,
DAMAGE TO THE VEHICLE, OR THE POSSIBILITY OF AN EXPLOSION

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
• Ensure the battery terminals are clean and the clamps are firm and
secure.
• Remove any vehicle battery filler plugs and check the electrolyte
level. If necessary, top up with distilled water.
• Ensure the area is well ventilated.
• Take great care not to touch the red positive (+) clamp against the
black negative (-) clamp.
1. Ensure the ON/OFF switch is in the OFF position.
2. Connect the red positive (+) clamp to the positive (+) battery terminal first.
Take care the clamp does not contact any moving parts or fuel lines.
3. Connect the black negative (-) clamp to the negative (-) battery terminal
or to a suitable earthing point on the vehicle chassis ensuring the
connections are firm and secure.
4. Switch the Jump-start, then the vehicle ignition ‘ON’ and leave in this
condition FOR APPROX TWO MINUTES. (This will provide the vehicle battery
with a short ‘boost’ charge to allow for easier starting).
5. Switch the ignition to ‘start’, for NO MORE than 6 seconds.
• If the engine does not start, within this time, SWITCH OFF the ignition
and wait for at least 3 minutes before trying again to prevent
damage to the jumpstarter due to overheating before trying again.
After this cooling off period, it is safe to resume trying to start the
vehicle.
6. Once the vehicle has started, turn the jump-start ON/OFF switch OFF.
7. Once the engine is running, disconnect the earthed clamp FIRST i.e. that
connected to the chassis or Negative terminal etc, and return it to its
storage position, then disconnect the Positive clamp from the battery
terminal, and restore to its storage position.
8. After use, always recharge the jump-start. If the battery is allowed to
remain in a discharged state, its life may be shortened.
9. Regularly check the charge level of the battery by pressing the TEST push-
button on the front panel.
WARNING: IT IS POSSIBLE THAT SOME ELECTRONIC EQUIPMENT COULD BE
DAMAGED BY JUMP STARTING. ALWAYS CHECK WITH THE CAR
MANUFACTURER’S HANDBOOK TO DETERMINE WHAT PRECAUTIONS IF
ANY SHOULD BE TAKEN.

USING AS A 12VOLT POWER SUPPLY
The unit has a cigar lighter type socket located on the side of the casing (see
page 6), that allows connection via a standard DC connector to other DC
electrical equipment.
WARNING: Be aware that a fully charged 12V battery can have an output of
approx.13.5V. Consult the appliance handbook to ensure it is safe to operate
from a 12V battery.
The table below indicates the approx. operating time from a fully charged
battery.
ESTIMATED OPERATING PERIOD PROVIDED
