Battery & Charger
Safety Instructions
We pay a great deal of attention to the design of every battery
pack to ensure that we supply you with batteries that are safe,
durable and have a high energy density. The battery cells have
range of safety devices. Each individual cell is initially
formatted and its electrical characteristic curves are recorded.
This data is then used exclusively to be able to assemble the
best possible battery packs.
Despite all the safety precautions, caution must always be
exercised when handling batteries. The following points must
be obeyed at all times to ensure safe use. Safe use can only be
guaranteed if undamaged cells are used. Incorrect handling of
the battery pack can cause cell damage.
IMPORTANT! Analyses confirm that incorrect use and poor
care of high performance batteries are the main factors
responsible for personal and/or product damage.
WARNING! Use only approved battery for
replacement; other batteries may damage the pressure
washer and cause it to malfunction, which can lead to
serious personal injury.
CAUTION! To reduce the risk of injury,
charge the lithium-ion battery pack only in its
designated lithium-ion charger.Other type of charges
present risk of fire,personal injury and damage. Do not
wire a battery pack to a power supply plug or car
cigarette lighter. Such misuse will permanently disable
or damage the battery pack.
·Avoid dangerous environments-Do not charge the
battery pack in rain, snow and in damp or wet location.
Do not use the battery pack or charge in the presence
of explosive atmosphere(gaseous fumes, dust or
flammable materials) because sparks may be
generated when inserting or removing the battery pack,
which could lead to a fire.
·Charge in a well-ventilated area- Do not block the
charge vents. Keep them clear to allow for proper
ventilation. Do not allow smoking or open flames near
a charging battery pack. Vented gases may exploded.
Note: The safe temperature range for the battery is -4
℉（-20℃to 113℉(45℃). Do not charge the battery
outside in freezing weather, charge at room
temperature.
·Maintain charge cord- When unplugging the charge,
pull the plug, not the cord, from the receptacle to
reduce the risk of damage to the electrical plug and
cord. Never carry the charge by its cord or yank it by
the cord to disconnect it from receptacle. Keep the cord
away from the heat, oil and sharp edges. Make sure the
cord will not be stepped on, tripped over or subject to
damage or street when the charge is in use. Do not use
the charge with a damaged cord or plug. Replace a
damaged charge immediately.
·Do not use an extension cord unless it is absolutely
necessary-Using the wrong, damaged or improperly
wired extension cord poses a risk of fire and electric
shock. If an extension cord must be used, plug the
charger into a properly wired 16 gauge or larger
extension cord with the female plug matching the male
plug with the female plug matching the male plug on
the charger. Make sure that the extension cord is in
good electrical condition.
·Charger- The charger must be plugged into an
appropriated receptacle.

battery packs from unplugged chargers.
WARNING! To reduce the risk of electric shock,
always unplug the charger before performing any cleaning or
maintenance. Do not allow water to flow into the charger.
·Do not burn or incinerate battery packs-Battery packs may
exploded, causing personal injury or damage. Toxic fumes and
materials are created when battery packs are burned.
·Do not crush, drop or damage battery packs- Do not use the
battery pack or charger if they have sustained a sharp blow,
been dropped, run over or have been damaged in any way(i.e.
Pierced with a nail, hit with a hammer, stepped on, etc.
·Do not disassemble – Incorrect reassembly may pose a
serious risk of electric shock, fire or exposure to toxic
battery chemicals. If the battery or charger are damaged,
contact an authorized customer service center for
assistance.
·Battery chemicals cause serious burns – Never let a
damaged battery pack contact the skin, eyes or mouth. If a
damaged battery pack leaks battery chemicals, use rubber
or neoprene gloves to safely dispose of it. If skin is
exposed to battery fluids, wash the affected area with soap
and water and rinse with vinegar. If eyes are exposed to
battery chemicals, immediately flush with water for 20
minutes and seek medical attention. Remove and dispose
of contaminated clothing.
·Do not short circuit – A battery pack will short circuit if a
metal object makes a connection between the positive and
negative contacts on the battery pack. Do not place a
battery pack near anything that may cause a short circuit,
such as paper clips, coins, keys, screws, nails and other
metallic objects. A short-circuited battery pack poses a
risk of fire and severe personal injury.
·Store your battery pack and charger in a cool, dry
place- Do not store the battery pack or charger where
temperatures may exceed 104℉(40℃), such as in direct
sunlight or inside a vehicle or metal building during the
summer.
Information about the batter
1. The battery pack supplied with your cordless
pressure washer is only partially charged. The
battery pack has to be charged completely before
you use the tool for the first time.
2. For optimum battery performance, avoid low
discharge cycles by charging the battery pack
frequently.
3. Store the battery pack in a cool place, ideally at
59℉(15℃) and charged to at least 40%.
4. Lithium-ion batteries are subject to a natural
aging process. The battery pack must be replaced
at the latest when its capacity falls to just 80% of
its capacity when new. Weakened cells in an aged
battery pack are no longer capable of meeting the
high power requirements needed for the proper
operation of your pressure washer, and therefore
pose a safety risk.
5. Do not throw battery packs into an open fire as
this poses a risk of explosion.
6. Do not ignite the battery pack or expose it to fire.
7. Do not exhaustively discharge batteries.
Exhaustive discharge will damage the battery
cells. The most common cause of exhaustive
discharge is lengthy storage or non-use of
partially discharged batteries. Stop working as
soon as the performance of the battery falls
noticeably or the electronic protection system
triggers. Place the battery pack in storage only
after it has been fully charged.
8. Protect batteries and the tool from overloads.
Overloads will quickly result in overheating and
cell damage inside the battery housing even if
this overheating is not apparent externally.
9. Avoid damage and shocks. Immediately replace
batteries that have been dropped from a height of
more than 3 feet (1m) or those that have been
exposed to violent shocks, even if the housing of
the battery pack appears to be undamaged. The
battery cells inside the battery may have suffered
serious damage. In such instances, please read
the waste disposal information for proper battery
disposal.
10. If the battery pack suffers overloading and
overheating, the integrated protective cutoff will
switch off the equipment for safety reasons.

5
IMPORTANT! Do not press the ON/OFF switch any more
if the protective cut-off has been activated. This may
damage the battery pack.
11. Use only original battery packs. The use of other
batteries poses a fire risk and may result in injuries or an
explosion.
Information about the charger and the
charging process
1. Please check the data marked on the rating plate of the
battery charger. Be sure to connect the battery charger
to a power supply with the voltage marked on the
rating plate. Never connect it to a different mains
voltage.
2. Protect the battery charger and its cord from damage.
Keep the charger and its cord away from heat, oil and
sharp edges. Have damaged cords repaired without
delay by a qualified technician at an authorized
customer service center.
3. Electrical plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
grounded appliances. Unmodified plugs and matching
outlets will reduce the risk of electric shock.
4. Keep the battery charger, battery pack(s) and the
cordless tool out of the reach of children.
5. Do not use the supplied battery charger to charge other
cordless tools.
6. During periods of heavy use, the battery pack will
become warm. Allow the battery pack to cool to room
temperature before inserting it into the charger to
recharge.
7. Do not overcharge batteries. Do not exceed the
maximum charging times. These charging times only
apply to discharged batteries. Frequent insertion of a
charged or partially charged battery pack will result in
overcharging and cell damage. Do not leave batteries in
the charger for days on end.
8. Never use or charge batteries if you suspect that it has
been more than 12 months since the last time they were
charged. There is a high probability that the battery
pack has already suffered dangerous damage
(exhaustive discharge).
9. Charging batteries at a temperature below 50℉(10℃)
will cause chemical damage to the cells and may cause
a fire.
10. Do not use batteries that have been exposed to
heat during charging process, as the battery cells
may have suffered dangerous damage.
11. Do not use batteries that have suffered curvature
or deformation during the charging process or
those that exhibit other atypical symptoms
(gassing, hissing, cracking, etc.).
12. Never fully discharge the battery pack (maximum
recommended depth of discharge is 80%). A
complete discharge of the battery pack will lead to
premature aging of the battery cells.
Protection from environmental influences
1. Wear suitable work clothes. Wear safety goggles.
2. Protect your cordless tool and the battery charger
from moisture and rain. Moisture and rain can
cause dangerous cell damage.
3. Do not use the cordless tool or the battery charger
near vapors and flammable liquids.
4. Use the battery charger and cordless tools only in
dry conditions and at an ambient temperature of
50-104℉(10-40℃).
5. Do not keep the battery charger in places where the
temperature is liable to reach over 104℉(40℃).In
particular, do not leave the battery charger in a car
that is parked in the sunshine.
6. Protect batteries from overheating. Overloads,
overcharging and exposure to direct sunlight will
result in overheating and cell damage. Never
charge or work with batteries that have been
overheated-replace them immediately, if possible.
7. Store the charger and your cordless tool only in dry
locations with an ambient temperature of
50-104℉(10-40℃). Store your lithium-ion
battery pack in a cool, dry place at a temperature
of 50-68℉(10-00℃). Protect the battery pack,

Charging a Hot or Cold Battery Pack
A red and green flashing indicator light on the charger
indicates that the battery pack temperature is outside the
charging range. Once the pack is within the acceptable
range,normal charging will take place and the red light will
be continuous. Hot or cold battery packs may take longer to
charge.
Operation
三IMPORTANT! This pressure washer is equipped
with a micro-switch sensitive to water flow. This Total
Stop System (TSS) senses water flow in the
pump.When the trigger is released, water stops flowing
through the pump . The TSS then automatically turns
the motor off to protect the pump from
overheating,thus saving energy and prolonging pump
life.
The TSS system will work only when there’s water in the
bucket or the base unit is connected with a water supply.
When there’s no water connected with the unit, the
On/Off button has to be pressed to stop the unit.
IMPORTANT! This system is capable of
producing 8Mpa. To avoid rupture and injury, do not
operate this pump with components rated less than 8Mpa
