5. HEALTH AND SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
Warning! Read all safety warnings, instructions, illustrations and specifications provided
with this power tool. Failure to follow all instructions listed below may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tools” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or
fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tools may
result in serious personal injury.
b) Use personal protective equipment Always wear eye protection. Protective equipment
such as a dust mask, non-skid safety shoes, hard hat or hearing protection use for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising power tools that have the
switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
– 6 –

5. HEALTH AND SAFETY INFORMATION
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing
away from moving parts. Loose clothes, jewellery or long hair can be caught in moving
parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce
dust-related hazards.
h) Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe injury
within a fraction of a second.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or remove the battery pack, if
detachable, from the power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
e) Maintain power tools and accessories. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could result
in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for safe handling and control of the tool in
unexpected situations.
5) Service
a) Have your power tool serviced by a qualified repair person using only identical
replacements parts. This will ensure that the safety of the power tool is maintained.
5.2 SPECIFIC SAFETY INSTRUCTIONS FOR PUMP USE

5. HEALTH AND SAFETY INFORMATION
5.3 RESIDUAL RISK
Important: Although the safety instructions and operating manuals for our tools contain extensive
instructions of safe working with power tools, every power tool involves a certain residual risk
which can not be completely excluded by safety mechanisms. Power tools must therefore always
be operated with caution!
5.4 SAFETY INSTRUCTIONS FOR MAINS POWERED CHARGERS &
BATTERY PACKS (NOT SUPPLIED)
– The charger (not supplied) is for indoor use only.
– Prior to plugging the charger in to the supply, check that the plug and the cable are in good
repair. If either are damaged, have the defective item replaced immediately by a suitably
qualified person. If the casing of the battery charger is damaged, it is good policy to have the
charger checked over by a suitably qualified person.
– Only use a correctly rated mains outlet to provide power, do not plug into site generators, attach to
engine generators or D.C. sources. Do not use a mains socket outlet that is not switched.
– Use the correct Draper charger in conjunction with it’s corresponding battery pack (consult the
Draper website for more information or to find your local Draper stockist).
– Do not charge any other batteries with Draper chargers. Any other application is considered misuse.
– Do not attempt to charge battery packs that are too hot (over 30ºC) or too cold (under 5ºC), if
these conditions apply set the battery pack aside to “normalise” before proceeding with the
charging operation.
– Set up the charger and cable in a safe place where it won’t be knocked, tripped over, stepped
on, etc. and where it is well ventilated. Make sure the ventilation slots in the charger case are
not obstructed, plug the charger into the socket outlet.
– Inspect the battery pack for damage, if it is undamaged, plug it into the charger, ensuring the
correct orientation. (Most chargers and batteries have ‘keys’ etc, to make sure the battery pack
is not inserted incorrectly, if you are having to ‘force’ the battery pack into the charger, the
chances are you have it the wrong way round, check and try again.)
– Switch the charger on and check that the correct indicators illuminate, allow the battery pack to
charge (see the specific instructions for your charger). Once charging is complete, switch the
charger off, remove the battery pack and store, repeat the procedure if you have more than
one battery pack to charge.
Caution: When the battery charger has been continuously used, the battery charger will be hot.
Once the charging has been completed, give 15 minutes rest until the next charge.
– After charging is complete, unplug the charger from the socket outlet by pulling on the plug. Do
not pull on the cable. Store the charger in a dry secure place.
– If, when the charger was switched on, the correct indications did not occur, leave for two or
three minutes to allow the charger to stabilise, if the correct indications occur, allow the
charging cycle to proceed as normal. If no indication appears at all, switch off, remove the
battery pack, unplug the charger, check that the charger contacts and the battery contacts are
clean and repeat the process. If there is still no indication, switch off, remove the battery pack,
unplug the charger and check the fuse. If the fuse is blown, replace and repeat the process. If
the fuse blows again, or if the fuse was intact, attempt no further action. Refer the charger to a
suitably qualified person for repair.

charger is malfunctioning. Allow battery/charger to
normalise and try again. If a fault remains after
trying this then contact Draper Tools.
9.2 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.
9.3 BATTERY PACK CHARGE
STATUS – FIGS. 7 – 8
To display the amount of charge left in the battery
pack, press the charge level indicator button (17.2).
9.4 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.

10. OPERATION AND USE
– 15 –
10.1 ‘PRIMING’THE PUMP – FIG.9
− Position the pump on flat and firm surface.
− Before operating the pump, it should be ‘primed’
with water, which is added through the priming
hole (2).
− Block off the outlet hose end of the pump so that
no water can drain out.
− Remove the screw-cap of the priming inlet
− Pour the water in through the priming hole slowly
and gradually until the water is overflowing from
the inlet hole.
10.2 SWITCHING ON
− The suction hose should be airtight, or air in the
hose will block the suction action of the liquid.
− The inlet of the suction hose should always be
submerged into the water in order to avoid
dry-running of the pump when the liquid level falls
(Fig.10).
− Make sure the suction hose does not lift up above
the pump, otherwise bubbles formed in the hose
might block the flow.
− Open any shut-off valves in the outlet hose
(injection nozzle, valves, etc.).
− Insert the battery pack.
− Start the pump by pressing the ON/OFF/pump
speed selection rocker switch (7).

11.2 MAINTENANCE
Regular inspection and cleaning reduces the necessity for maintenance operations and will keep
your tool in good working condition.
The pump is basically maintenance free. To ensure a long service life, however, we recommend
regular checks and care.
Warning! Before any maintenance or adjustment, switch off the pump and remove the battery
pack.
If the pump is not going to be used for a long time or has to be removed for the winter months,
rinse it out with water, empty it completely and allow it to dry.
− If there is a risk of frost, the pump must be completely empty and dry.
− After long periods of non-use, make sure the rotor turns correctly by briefly switching the pump
on and off.
− If the pump becomes blocked, connect the pressure line to the water line and remove the
intake hose. Open the water line, Switch on the pump several times for approx. 2 seconds.
Most blockages can be removed in this way.
Warning! The pump must never be allowed to run dry!
