5. HEALTH AND SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
When using any type of power tool there are steps that should be taken to make sure that you, as
the user, remain safe.
Common sense and a respect for the tool will help reduce the risk of injury.
Read the instruction manual fully. Do not attempt any operation until you have read and
understood this manual.
Most important you must know how to safely start and stop this machine, especially in an
emergency.
Keep the work area tidy and clean. Attempting to clear clutter from around the machine during
use will reduce your concentration. Mess on the floor creates a trip hazard. Any liquid spilt on the
floor could result in you slipping.
Find a suitable location. If the machine is bench mounted, the location should provide good
natural light or artificial lighting as a replacement. Avoid damp and dust locations as it will have a
negative effect on the machine’s performance. If the machine is portable do not expose the tool to
rain. In all cases do not operate power tools near any flammable materials.
Keep bystanders away. Children, onlookers and passers by must be restricted from entering the
work area for their own protection. The barrier must extend a suitable distance from the tool user.
Unplug and house all power tools that are not in use. A power tool should never be left unattended
while connected to the power supply. They must be housed in a suitable location, away locked up
and from children. This includes battery chargers.
Do not overload or misuse the tool. All tools are designed for a purpose and are limited to what
they are capable of doing. Do not attempt to use a power tool (or adapt it in any way) for an
application it is not designed for. Select a tool appropriate for the size of the job. Overloading a tool
will result in tool failure and user injury. This covers the use of accessories.
Dress properly. Loose clothing, long hair and jewellery are all dangerous because they can
become entangled in moving machinery. This can also result in parts of body being pulled into the
machine. Clothing should be close fitted, with any long hair tired back and jewellery and neck ties
removed. Footwear must be fully enclosed and have a non-slip sole.
Wear personal protective equipment (PPE). Dust, noise, vibration and swarf can all be
dangerous if not suitably protected against. If the work involving the power tool creates dust or
fumes wear a dust mask. Vibration to the hand, caused by operating some tools for longer periods
must be protected against. Wear vibration reducing gloves and allow long breaks between uses.
Protect against dust and swarf by wearing approved safety goggles or a face shield. These are
some of the more common hazards and preventions, however, always find out what hazards are
associated with the machine/work process and wear the most suitable protective equipment
available.
Do not breathe contaminated air. If the work creates dust or fumes connect the machine (if
possible) to an extraction system either locally or remotely. Working outdoors can also help if
possible.
Move the machine as instructed. If the machine is hand held, do not carry it by the power supply
cable. If the product is heavy, employ a second or third person to help move it safely or use a
mechanical device. Always refer to the instructions for the correct method.
Do not overreach. Extending your body too far can result in a loss of balance and you falling. This
could be from a height or onto a machine and will result in injury.
Maintain your tools correctly. A well maintained tool will do the job safely. Replace any damaged
or missing parts immediately with original parts from the manufacturer. As applicable, keep blades
sharp, moving parts clean, oiled or greased, handles clean, and emergency devices working.
Wait for the machine to stop. Unless the machine is fitted with a safety brake, some parts may
continue to move due to momentum. Wait for all parts to stop, then unplug it from the power supply
– 6 –

5. HEALTH AND SAFETY INFORMATION
before making any adjustments, carrying out maintenance operations or just finishing using the
tool.
Remove and check setting tools. Some machinery requires the use of additional tools or keys to
set, load or adjust the power tool. Before starting the power tool always check to make certain they
have been removed and are safely away from the machine.
Prevent unintentional starting. Before plugging any machine in to the power supply, make sure
the switch is in the OFF position. If the machine is portable, do not hold the machine near the
switch and take care when putting the machine down, that nothing can operate the switch.
Carefully select an extension lead. Some machines are not suitable for use with extension
leads. If the tool is designed for use outdoors, use an extension lead also suitable for that
environment. When using an extended lead, select one capable of handling the current (amps)
drawn by the machine in use. Fully extend the lead regardless of the distance between the power
supply and the tool. Excess current (amps) and a coiled extension lead will both cause the cable to
heat up and can result in fire.
Concentrate and stay alert. Distractions are likely to cause an accident. Never operate a power
tool if you are under the influence of drugs (prescription or otherwise), including alcohol or if you
are feeling tired. Being disorientated will result in an accident.
Have this tool repaired by a qualified person. This tool is designed to conform to the relevant
international and local standards and as such should be maintained and repaired by someone
qualified, using only original parts supplied by the manufacturer. This will ensure the tool remains
safe to use.

1. PREPARING THE GRASS & HEDGE TRIMMER
Caution: If the battery charger has been in
continuous use it will be hot. Once the charging
has been completed, leave the charger 15 minutes
to cool until next use. If the battery is charged
when it is warm due to battery use or exposure to
sunlight, the battery will not be recharged. In such
a case, let the battery cool before charging.
If the red indicator flickers rapidly at 0.2 second
intervals, check or and remove any foreign objects
in the charger’s battery slot. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Allow battery/charger to normalise
and try again. If a fault remains after trying this
then contact Draper Tools.
8.2 BATTERY PACK PROTECTION
FEATURES
Overcharging protection: This feature that
ensures that the battery pack can never be
overcharged. When the battery pack reaches full
charge capacity, the transformer/charger will
automatically shut off, protecting the internal
components from being damaged.
Over-discharging protection: This feature will stop the battery pack from discharging beyond the
recommended lowest safety voltage.
Overheating protection: The battery pack contains an internal thermistor cut-off sensor which
shuts off the battery pack should it become too hot during operation. This can happen if the tool is
overloaded or being used for extended periods. Up to 30 minutes cooling time may be required,
depending on ambient temperature.
Current protection: Should the battery be overloaded and the maximum current draw be
exceeded, the battery will shut off to protect the internal components. The battery pack will
resume working once excessive current draw has returned to normal, safe level.
Short circuit protection: If, for any reason, the battery pack was to short circuit, the short circuit
protection would immediately stop the battery pack from operating.
8.3 BATTERY PACK CHARGE STATUS – FIG. 3
To display the amount of charge left in the battery pack, press the charge level indicator button (7.2).
8.4 BATTERY LIFE EFFICIENCY AND CHARGING ADVICE
– Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after use. If
such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and
the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.
– The battery should only be used and/or charged when battery temperature is between 5°C and 30°C.
– The battery needs to be warmed-up or cooled down in order to prevent damage to the batteries
internal components,
Note: If battery is too hot or too cold, allow it to ‘normalise’ before use or charging.
Note: Failure to warm up or cool down a battery could result in serious damage to the battery,
charger and user.
