Original Language Version
Under these circumstances only AND ONLY having verified the battery on the vehicle has a voltage of 24V
, briefly press the
manual override button on the front panel to bypass the safety function. this will manually close and hold closed the circuit until the
clamps are removed from the vehicles battery. If the override switch is accidentally pressed, then breaking the connection to the
vehicle’s battery by removing the battery clamp will reset the safety circuit.
WARNING! DO NOT ACTIVATE THE OVERRIDE IF THE ROADSTART IS SWITCHED TO 24V AND THE VEHICLE’S BATTERY
CIRCUIT IS 12V
If the vehicle’s battery is below 0.7V then the circuit cannot be closed – even using the override. In this case, recharge the vehicle’s
battery using conventional means.

Boosting/Re-Charge vehicle battery
WARNING!
do not allow the red and black battery clamps to touch each other. ensure that the correct clamps are placed on the cor
rect battery terminals.
4.2.1.
site roadstart on level surface.
4.2.2.
ensure power switch is in the off position.
4.2.3.
connect red positive clamp (+) to the positive (+) battery terminal on the vehicle and BlAcK negative (-) clamp to a good earth on
the vehicle bodywork. only connect BlAcK negative (-) clamp directly to battery negative (-) terminal if no other alternative is
available.
4.2.4.
Allow the vehicle battery to charge for thirty minutes.
4.2.5.
turn off the roadstart, remove the battery clips (negative(-) first) and start the vehicle.
4.3.
12V System only
4.3.1.
It is possible to recharge the vehicle battery using the roadstart’s own in-car charger cable.
4.3.2.
site roadstart on level surface.
4.3.3.
ensure power switch is in the off position.
4.3.4.
Plug one end of the charging lead into the roadstart unit. Plug the other end into the vehicle’s 12V accessory socket. note: some
vehicle ignition systems must be turned to
“Accessory”
to activate the accessory socket.
4.3.5.
Allow the vehicle battery to charge for thirty minutes.
4.3.6.
turn off the roadstart, remove the charging lead and start the vehicle.
IMPORTANT! It is not possible to charge 24V battery systems using the in-car adaptor lead. The accessory socket on the
front of the unit is rated at 12V only.
IMPORTANT!
If the voltage in the vehicles battery is between 0.7V and 16V when boosting a 24V system, press the relay switch
(fig.1.17) or the roadstart will not charge the battery.
If the voltage is below 0.7V it is not possible to deliver any charge to the battery. charge the battery using conventional means.
4.4.
Emergency Jump Starter
IMPORTANT:
do not use the roadstart to jump start an vehicle if only the amber Battery Power level light is illuminated. this
denotes the internal voltage is less than 7V. Permanent damage to the roadstart’s internal batteries will be made if you attempt to
jump start a vehicle with only the amber Battery Power level light Illuminated.
WARNING!
do not allow the red and black clamps to touch each other. ensure that the correct clamps are placed on the correct bat
tery terminals.
NOTE:
If the clamps are connected incorrectly to vehicle’s battery, the roadstart will not operate, the charging led's will flash and
the roadstart will buzz. see section 4.1
NOTE:
for optimum performance, the unit should not be stored below 10°c when using the unit as a jump starter.
4.4.1.
turn off the vehicle ignition.
4.4.2.
site roadstart on level surface.
4.4.3.
ensure power switch is in the off position.
4.4.4.
Attach the red (po) clamp to the positive terminal of the battery.
NOTE:
on vehicles with multiple batteries, ensure the battery to which you are connecting the roadstart is the battery which pro
vides power to the starting system and is not an auxiliary power battery.
4.4.5.
Attach the BlAcK (negative -) clamp to the vehicle chassis. only connect BlAcK negative (-) clamp directly to battery negative (-)
terminal if no other alternative is available.
4.4.6.
turn the roadstart power control to 12V or 24V depending on the battery circuit voltage of the vehicle you are jump starting.
NOTE: IN the case of incorrect connection, the unit will emit a buzzing sound and the LED’s on the Battery Power Level
will flash – Check connection to vehicle, Roadstart power switch position and vehicle’s battery voltage.
Refer to the table in
4.1 for safety circuit characteristics and reconnect/configure as appropriate.
IMPORTANT!
If the voltage in the vehicles battery is between 0.7V and 16V when jump starting a 24V system, press the relay
switch (fig.1.17) or the roadstart will not operate.
If the voltage is below 0.7V it is not possible to deliver any power to the battery. charge the battery using conventional means.
ensure that all cables are clear of moving belts and rotating fans.Maintain a safe distance from the battery whilst jump starting.
4.4.7.
turn the ignition to start the vehicle.
NOTE:
If the vehicle does not start after 6 seconds, allow the roadstart unit to cool for 3 minutes, before attempting to jump start
the vehicle again. If this is not done, the unit could sustain damage.
4.4.8.
When the vehicle has started, disconnect the BlAcK (negative -) clamp first from the vehicle chassis.
4.4.9.
remove the red (po) clamp from the battery terminal.
4.4.10. return the clamps to the designated holsters.
4.5.
Alternative Vehicle Power Supply
When a vehicle battery is disconnected, the memory systems in radios, electronic ignition systems and alarms are frequently lost.
When replacing a battery the roadstart unit can be used as an alternative power supply by connecting the unit’s in-car power
adaptor dc adaptor lead from the 12V socket on the front of the unit into the vehicle’s accessory socket.
this will prevent loss of memory.
