5.1 GENERAL SAFETY INSTRUCTIONS

WARNING: Please read the following instructions carefully, failure to do so could lead to serious
personal injury.
IMPORTANT: Draper Tools Limited recommends that this machine should not be modified or used for
any application other than that for which it was designed. If you are unsure of its relative applications do
not hesitate to contact us in writing and we will advise you.

WARNING - RISK OF EXPLOSIVE GASES

WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS, BATTERIES GENERATE
EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF
UTMOST IMPORTANCE, IF YOU HAVE ANY DOUBT, THAT EACH TIME BEFORE USING THE
POWER PACK, YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS.

- To reduce risk of battery explosion, follow these instructions and those published by the battery
manufacturer and manufacturer of any equipment you intend to use in the vicinity of the battery.
Review warning marks on all these products and on the engine.

- When working near a lead-acid battery, someone should be within range of your voice, close enough
to come to your aid.

- Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.

- Wear complete eye, hand and clothing protection. Avoid touching eyes when working with batteries.

- If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eyes,
immediately flood eye with cool, clean running water for at least 15 minutes and get medical attention
immediately.

- NEVER smoke or allow a spark or flame in vicinity of battery or engine.

- Be extra cautious to reduce risk of dropping a metal tool onto a battery. It could spark or short circuit
the battery or, any other electrical part possibly causing an explosion.

- When working with a lead-acid battery, remove personal metallic items such as rings, bracelets,
necklaces and watches. A lead-acid battery can produce a short-circuit current high enough to weld a
ring, or the like to metal, which may cause severe burns.

- Use the battery charger for charging “lead-acid batteries only”. Do not use for charging dry-cell or
Ni-Cad batteries that are commonly used with home appliances. For example, radios, torches etc.
These batteries may explode and cause injury to persons and damage to property.

- NEVER charge or boost a frozen battery.

- NEVER allow clamps to touch one another or to contact the same piece of metal to prevent arcing.

- Ensure the power pack is switched off prior to connecting/disconnecting of the vehicle battery.

- Do not use the charger in damp or wet conditions.

- Keep out of reach of children.

- Do not submerge in water.

- Do not operate near flammables such as petrol, paraffin, or thinners etc.

If the charger receives a sharp blow or is otherwise damaged in any way, do not disassemble. Have it

checked by a qualified service person. Return to source.

- The battery must be removed from the appliance before it is scrapped.

- The appliance must be disconnected from the supply mains when removing the battery.

- The battery must be disposed of safely.

- This appliance is for use on 12V circuits only.

- Do not use in high temperatures.

- Before connecting the power pack, ensure the main switch is in the ‘off’ position.

- If incorrect polarity is indicated, disconnect immediately and rectify.

- Prior to initial use charge for 24 hours.

- Do not use the power pack while charging.

5. HEALTH & SAFETY INFORMATION

5.2 RECHARGEABLE BATTERIES:

- The battery must be removed from the appliance before it is scrapped.

- The appliance must be disconnected from the supply mains when removing the battery.

- The battery must be disposed of safely

- Charge the battery using the specified charger under the charging conditions specified.
Charging the battery under any other conditions may cause the battery to overheat, emit hydrogen

gas, leak, ignite or burst.

- Do not place the battery near a device that may cause sparks (such as a switch or a fuse). The
battery may generate flammable gas when charged, so remember to keep the battery away from fire
to prevent sparks from igniting or causing explosion.

- Do not place or store the battery in a vehicle in hot weather, under direct sunlight, or near a source
of heat. Use and storage of the battery in these conditions may cause battery leakage, fire or
bursting.

- Damage and deterioration of battery characteristics may occur if the battery is dropped.

- Do not charge the battery in the inverted position.

- Do not carry the battery by hanging it from the terminal or the cable, as it may cause damage to the
battery.

- Turn off the switch of the circuit when connecting the battery to a charger or load.

- Batteries tend to lose a part of their capacity due to self-discharge during shipment and storage,
recharge the batteries before you use them and after purchase or long-term storage in order to
restore their full capacity.

- Do not continue discharging to the point where the voltage drops below the recommended discharge
cut-off voltage.

If a storage battery that was discharged below the recommended discharge cut-off voltage is

recharged, the storage battery may generate heat which could deform it or cause condensation to
form moisture from inside the battery.

Discharging below the recommended voltage may also accelerate the deterioration of the battery's

performance characteristics.

- Avoid overdischarge, and charge the battery immediately after discharge.

- Unsatisfactory storage conditions may cause deterioration in battery performance, shorten service
life and could cause rust to form on the terminals.

- Do not allow metallic objects to touch or bridge the terminals especially jewellery. Failure to observe
the precautions may cause the battery to overheat, emit hydrogen gas, leak, ignite or burst.

- Do not throw the battery into fire or heat the battery. The battery may burst or generate a toxic gas if
placed in contact with fire.

- Do not attempt to disassemble, remodel or destroy the battery, as it may cause the battery leakage,
fire or bursting, and could also create sulphuric acid spills from the battery resulting in possible burns
to personnel and damage to the immediate environment.

- Do not continue to charge the battery beyond the time specified in the instructions. If the battery is
not fully charged even after being charged for a longer time than specified, discontinue charging and
remove the battery from the charger. Charging for a longer time than specified may cause the
battery to leak, ignite, or burst.

- Do not discharge the batteries beyond the maximum values indicated on the battery. If the battery is
discharged beyond the maximum values, it may leak, ignite or burst.

- Keep the batteries beyond the reach of children.

- Wear gloves when handling batteries.

5. HEALTH & SAFETY INFORMATION

- Do not apply organic solvents such as paint thinner, petrol or liquid detergents to the battery.
If these are brought into contact with the battery case, it may crack, causing leakage.

- The car’s battery contains electrolyte (diluted sulphuric acid) a very toxic substance. If the battery
leaks and the liquid inside spills on the skin or clothing, immediately wash it off with plenty of clean
water. If the liquid splashes into eyes, immediately flush the eyes with plenty of clean water and
consult a doctor. Sulphuric acid will burn skin and in the eyes may cause loss of eyesight.

- Store the battery in a stable position so as to keep the terminals of the battery away from any
metallic or other conductive material (including items that may fall or drop onto the battery).

Protect the battery from rain. If the terminals of the battery come into contact with water, they may

corrode.

As a general rule, keep the battery in an upright position.
When storing the battery, disconnect it from the charger and keep it in a place where the

temperature is low. Do not store in direct sunlight or temperatures exceeding 60°C.

If the battery is stored for a year or longer without being charged, its service life may be shortened.

Store the battery after fully charging it, otherwise its service life may be shortened.

- Use/recharge the battery regularly. The battery gradually deteriorates during storage and
consequently its decreased capacity may be irreversible even after recharging.

Used batteries are recyclable. When returning used batteries, insulate their terminals with
adhesive tape if not the residual electricity in used batteries may cause fire or explosion.
This battery is fully recyclable and should be accepted at any location that excepts common
automotive batteries. Contact your national/local authority or municipal waste centre for details.

BATTERY CHARGERS:

- Before charging, read the instructions.

- For indoor use. Do not expose to rain.

- Disconnect the supply before making or breaking the connections to the battery.
