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 a wide 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.
WARNING!
Use only approved replacement
batteries; other batteries may damage the cordless paint
sprayer and cause it to malfunction, which can lead to
personal injury.
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!
Do not use a battery pack or
appliance that is damaged or modified. Damaged or
modified batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
Do not modify or attempt to repair the appliance or the
battery pack except as indicated in the instructions for
use and care.
Have your battery pack serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the battery pack is maintained.
To reduce the risk of injury, charge the
40V lithium-ion battery pack only in its designated
40V lithium-ion charger. Other types of chargers 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 or in damp or wet locations.
Do not use the battery pack or charger in the presence
of explosive atmospheres (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
charger vents. Keep them clear to allow for proper
ventilation. Do not allow smoking or open flames near
a charging battery pack. Vented gases may explode.
NOTE: The safe temperature range for the battery is
41°F – 105°F (5°C – 40.5°C). Do not charge the battery
outside in freezing weather; charge it at room temperature.
• Maintain charger cord – When unplugging the charger,
pull the plug, not the cord, from the receptacle to
reduce the risk of damage to the electrical plug and cord.
Never carry the charger by its cord or yank it by the cord
to disconnect it from the receptacle. Keep the cord away
from heat, oil and sharp edges. Make sure the cord will
not be stepped on, tripped over or subjected to damage
or stress when the charger is in use. Do not use the
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. Use a Ground Fault Circuit Interrupter (GFCI)
to reduce shock hazards.
•Do not burn or incinerate battery packs – Battery
packs may explode, 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 the Litheli customer service E-mail
(servic[email protected]om).

Information about the battery
1. The battery pack supplied with your cordless paint
sprayer 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 77°F
(25°C) 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
paint sprayer, 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 one meter 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.
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
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 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 connecting it to 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
connected to 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 41°F (5°C)
will cause chemical damage to the cells and may cause
a fire.
10. Do not use batteries that have been exposed to heat
during the 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
41°F – 105°F (5°C – 40.5°C).
5. Do not keep the battery charger in places where the
temperature is liable to reach over 105°F (40.5°C). In
particular, do not leave the battery charger in a car
that is parked in the sunshine.
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 Litheli
dealer contact the Litheli customer service E-mail
