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.
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.

Charge Indicators
FCharging I
GFully Charged J
HHot/Cold Pack Delay* K
*The red light will continue to blink, but a yellow indicator light
will be illuminated during this operation. Once the battery pack
has reached an appropriate temperature, the yellow light will
turn off and the charger will resume the chargingprocedure.
The compatible charger(s) will not charge a faulty battery pack.
The charger will indicate faulty battery by refusing tolight.
NOTE: This could also mean a problem with acharger.
If the charger indicates a problem, take the charger and battery
pack to be tested at an authorised servicecentre.
Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot or too
cold, it automatically starts a Hot/Cold Pack Delay, suspending
charging until the battery pack has reached an appropriate
temperature. The charger then automatically switches to the pack
charging mode. This feature ensures maximum battery packlife.
A cold battery pack will charge at a slower rate than a warm
battery pack. The battery pack will charge at that slower rate
throughout the entire charging cycle and will not return to
maximum charge rate even if the battery packwarms.
The DCB118 charger is equipped with an internal fan designed to
cool the battery pack. The fan will turn on automatically when the
battery pack needs to be cooled. Never operate the charger if the
fan does not operate properly or if ventilation slots are blocked.
Do not permit foreign objects to enter the interior of thecharger.
Electronic Protection System
XR Li-Ion tools are designed with an Electronic Protection
System that will protect the battery pack against overloading,
overheating or deepdischarge.
CAUTION: Burn hazard. To reduce the risk of injury,
charge only DeWALT rechargeable batteries. Other types of

checkedbaggage.
DeWALT batteries comply with all applicable shipping
regulations as prescribed by industry and legal standards, which
include UN Recommendations on the Transport of Dangerous
Goods; International Air Transport Association (IATA) Dangerous
Goods Regulations; International Maritime Dangerous Goods
(IMDG) Regulations; and the European Agreement Concerning
The International Carriage of Dangerous Goods by Road
(ADR). Lithium-ion cells and batteries have been tested to
section 38.3of the UN Recommendations on the Transport of
Dangerous Goods Manual of Tests andCriteria.
In most instances, shipping a DeWALT battery pack will
be excepted from being classified as a fully regulated
Class9Hazardous Material. In general, only shipments containing
a lithium-ion battery with an energy rating greater than 100Watt
Hours (Wh) will require being shipped as fully regulated Class9.
All lithium-ion batteries have the Wh rating marked on the pack.
Furthermore, due to regulation complexities,
DeWALT does
not recommend air shipping lithium-ion battery packs alone
regardless of Wh rating. Shipments of tools with batteries (combo

DCB185, DCB187, DCB189, DCBP034, DCBP034G, DCBP518,
DCBP518G. Refer to Technical Data for moreinformation.
p Refer to Technical Data for chargingtime.
q Do not probe with conductiveobjects.
r Do not charge damaged batterypacks.
s Do not expose towater.
t Have defective cords replacedimmediately.
u Charge only between 4˚C and 40˚C.
v Only for indooruse.
x Discard the battery pack with due care for
theenvironment.
y Charge DeWALT battery packs only with designated
DeWALT chargers. Charging battery packs other than
the designated DeWALT batteries with a DeWALT
charger may make them burst or lead to other
dangeroussituations.
z Do not incinerate the batterypack.
B USE (without transport cap). Example: Wh rating
indicates 108Wh (1battery with 108Wh).
A TRANSPORT (with built-in transport cap). Example: Wh
rating indicates 3x 36Wh (3batteries of 36Wh).
Regardless of whether a shipment is considered excepted
or fully regulated, it is the shipper's responsibility to consult
the latest regulations for packaging, labeling/marking and
documentationrequirements.
The information provided in this section of the manual is
provided in good faith and believed to be accurate at the time
the document was created. However, no warranty, expressed or
implied, is given. It is the buyer’s responsibility to ensure that its
activities comply with the applicableregulations.
Transporting the FLEXVOLTTM Battery
The DeWALT FLEXVOLT® battery has two modes: Use
andTransport.
Use Mode: When the FLEXVOLTTM battery stands alone or is in
a DeWALT 18V product, it will operate as an 18V battery. When
the FLEXVOLTTM battery is in a 54V or a 108V (two 54V batteries)
product, it will operate as a 54Vbattery.
Transport Mode: When the cap is attached to the FLEXVOLTTM
battery, the battery is in Transport mode. Keep the cap
forshipping.
When in Transport mode, strings
of cells are electrically
disconnected within the pack,
resulting in 3batteries with a
lower Watt hour (Wh) rating as compared to 1battery with a
higher Watt hour rating. This increased quantity of 3batteries
with the lower Watt hour rating can exempt the pack from
certain shipping regulations that are imposed upon the higher
Watt hour batteries.
For example, the Transport
Wh rating might indicate
3x36Wh, meaning
3batteries of 36Wh each.
The Use Wh rating might
indicate 108Wh (1batteryimplied).
Storage Recommendations
1. The best storage place is one that is cool and dry away from
direct sunlight and excessive heat or cold. For optimum
battery performance and life, store battery packs at room
temperature when not inuse.
2. For long storage, it is recommended to store a fully charged
battery pack in a cool, dry place out of the charger for
optimalresults.
NOTE: Battery packs should not be stored completely
depleted of charge. The battery pack will need to be recharged
beforeuse.
Labels on Charger and Battery Pack
In addition to the pictographs used in this manual, the

Lubrication
Your power tool requires no additionallubrication.
Blade Maintenance (Fig. H)
The cutting blades are made from high quality, hardened steel
and with normal usage, they will not require resharpening.
However, if you accidentally hit a wire fence (Fig.H), stones,
glass, or other hard objects, you may put a nick in the blade.
There is no need to remove this nick as long as it does not
interfere with the movement of the blade. If it does interfere,
remove the battery and use a fine toothed file or sharpening
stone to remove the nick. If you drop the trimmer, carefully
inspect it for damage. If the blade is bent, housing cracked,
handles broken or if you see any other condition that may affect
the tool's operation contact your local authorized service center
for repairs before putting it back intouse.
Blade Lubrication (Fig. A)
1. After use, remove thebattery8.
2. Carefully apply a resin solvent to the exposedblades.
3. Insert the battery and turn the tool vertical with the blades
toward the ground and run the tool for a few seconds to
fully disperse thelubrication.
Storage (Fig. A)
1. After use, remove thebattery.
2. Keeping your hands away from the blade, slide the blade
cover10 over the blade until it snaps into place as shown
in Fig.A.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regularcleaning.
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can causeinjury.
The charger and battery pack are notserviceable.
Trimming Instructions (Fig. C–G)
DANGER: Keep hands away fromblade .
WARNING: To guard against injury, observe the following:
• Read instruction manual before using. Save
instructionmanual.
• Check the hedge for foreign objects such as wires or
fences before eachuse.
• Keep hands on handles. Don’toverreach.
• Do not use under wetconditions.
CAUTION: Blade may coast after turnoff.
CAUTION: Do not use blade to cut stems greater than
32mm. Use the trimmer only for cutting normal shrubbery
around houses andbuildings.
Working Position (Fig.D)
Maintain proper footing and balance and do not overreach.
Wear safety goggles, non-skid footwear and gloves when
trimming. Hold the tool firmly in both hands and turn the
tool ON. Always hold the trimmer, as shown in Fig. D. Refer to
Proper Hand Position for more information. Never hold the
tool by the bladeguard.
Trimming New Growth (Fig.E)
Using a wide, sweeping motion and feeding the blade teeth
through the twigs, is most effective. A slight downward tilt of
the blade in the direction of motion gives the bestcutting.
Level Hedges (Fig.F)
To obtain exceptionally level hedges a piece of string can be
stretched along the length of the hedge as aguide.
Switching On (Fig. A, C, D)
WARNING: Never attempt to lock a switch in the
ONposition.
1. Squeeze the bail handle switch4 and the bail handle5
with one hand so that the bail handle switch4 is pushed
into the body of the bail handle5.
2. Push the lock off switch2 forward and squeeze the trigger
switch 1. Once the unit is running, you may release the
lock offswitch.
3. In order to keep the unit running you must continue to
squeeze the bail handle switch4 and trigger switch 1.
4. To turn the unit off, release the trigger switch1.
