SAFETY -Important Guidelines
RISK OF EXPLOSION
Explosive gases may escape during charging. This is normal, but please follow the
following guidelines:
• Do
not charge near flames or sparks - do not smoke in the area.
• Ensure adequate ventilation during charging.
• Keep the charging area completely clear of combustible materials.
Do not allow battery
to overheat by exceeding 40°C.
Store and use indoors only.
The charger is designed
to charge 6v and 12v Lead-Acid & AGM batteries with
capacities 1.2Ah
to 120Ah (Ampere hours) only. Charge only one battery at a time.
Do not use with non-rechargeable batteries.
This charger should not be used as a continuous DC power source or for any
purposes other than those listed -any other use will invalidate warranty.
• Ensure that cables are regularly inspected and kept
in good condition.
Never use the appliance if the charger, mains lead, plug, output leads or crocodile
clips are damaged.
• Replacement of the mains cable should only be carried out
by the manufacturer.
There are no user-serviceable parts
in this product other than the fuse in the
output
and inputieads.
• Always disconnect mains supply before connecting and disconnecting the
battery leads.
• Follow instructions for safe use -electrical discharge from batteries can
be dangerous.
• Battery electrolyte is acidic and likely
to cause burns. The use of safety goggles and
gloves when working with lead acid batteries is strongly advised.
• This appliance is not for use by a person (including children) with reduced physical,
sensory
or medical capabilities or lack of experience or knowledge.

Output lead fuses should be checked and replaced as necessary (SA blade) in connection with all faults.
Also check the fuse in the mains plug , which should only be replaced with a 3A BS1362 fuse . Persistant
fuse replacement may indicate a fault with the charger or leads. Check these before each use and do not
use if worn or damaged.

1. Preparation of battery
Refer to the vehicle manufaturer's handbook for battery maintenance guidelines.
2. Charging lead selection
Interchangeable ring terminal and fully-insulated battery clip charging leads are supplied.
• Select the appropriate lead for your application. Quick fit ring terminal leads are
useful for applications where the battery is not easily accessible
(e.g. some motorcycles).
• Attach to the charger output lead using the quick-fit connector (fitted to each).
This must be done before connecting the charger to either the mains supply or
to the battery.

CONNECTION
Always disconnect the mains supply before making or breaking battery connections.
Connect the battery clips or ring terminals to the battery
in the foll<;>wing order:
1. Connect the positive charging lead (RED) to the positive post of the battery
(marked + , +ve or
P).
2. For vehicles with the battery still installed: connect the negative charging lead (BLACK)
to the vehicle chassis (marked - , -ve or N), well away from the battery, fuel line, and hot
or moving parts.
For batteries removed from the vehicle: Connect the negative charging lead (BLACK) to the
negative post of the battery (marked - / -ve
or N).
After connecting the clips, rotate them slightly so as to remove any dirt or oxidization, thus
ensuring a good contact.
CHARGING
WARNING! DO NOT ATTEMPT TO START THE VEHICLE WITH THE CHARGER
CONNECTED TO THE BATTERY. THIS MAY DAMAGE YOUR BATTERY CHARGER.
Switch on the mains power supply. For 12V batteries select the charging mode appropriate
for your battery by pushing the MODE button. The display will cycle through the available
options (12V
STD, 12V AGM, WINTER). The charger will now automatically measure the
voltage of your battery and diagnose its condition. For 6V batteries the charger will
automatically commence the
6V STD charging program.
WHEN CHARGING IS COMPLETE
Switch off the mains supply, unplug the charger and disconnect the clips from the battery,
negative (BLACK lead) first. Then disconnect the (RED) positive lead from the battery.
Or, if used, disconnect the ring terminal charging lead in the same way. If desired, this lead
can be left permanently attached to a vehicle battery, but the end-cap must be fitted to
the quick-fit connector at
all times to prevent short circuit, sparks or dirt and water entry.
When not in use the charger should NOT be left connected to this lead.
