13. Check Damaged Parts - Before further use of the
appliance, a guard or other part that is damaged
should be carefully checked to determine that it will
operate properly and perform its intended function.
Check for alignment of moving parts, binding of
moving parts, breakage of parts, mounting, and any
other condition that may affect its operation. A guard
or other part that is damaged should be properly
repaired or replaced by a qualified technician unless
indicated elsewhere in this manual.
14. Wear full eye protection and protective clothing.
15. If electrolyte contacts the skin, wash it off
immediately with water.
16. If electrolyte contacts the eyes, flush thoroughly
and immediately with water. Seek medical attention.
Blower Safety
1. Do not put any object into openings. Do not use
with any opening blocked; keep free of dust, lint,
hair, and anything that may reduce air flow.
2. Keep hair, loose clothing, fingers, and all parts of
body away from openings and moving parts.
3. Use extra care when cleaning on stairs.
4. Do not use to pick up flammable or
combustible liquids, such as gasoline, or

not blow debris in the direction of people,
animals or property.
7. Use only accessories provided. Keep guards in
place and in working order.
8. Maintain labels and nameplates on the
appliance. These carry important safety
information. If unreadable or missing, contact
Litheli for a replacement.
9. The battery Charger gets hot during
use. The Charger’s heat can build up to
unsafe levels and create a fire hazard if
it does not receive adequate ventilation,
due to an electrical fault, or if it is used in a hot
environment.
Do not place the Charger on a flammable surface.
Do not obstruct any vents on the Charger.
Especially avoid placing the Charger on carpets
and rugs; they are not only flammable, but they
also obstruct vents under the Charger.
Place the Charger on a stable, solid, nonflammable
surface (such as a stable metal workbench or
concrete floor) at least 1 foot away from all
flammable objects, such as drapes or walls. Keep a
fire extinguisher and a smoke detector in the area.
Frequently monitor the Charger and
Battery Pack while charging.
10. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
11. The warnings, precautions, and instructions
discussed in this instruction manual cannot cover
all possible conditions and situations that may
occur.
It must be understood by the operator that
common sense and caution are factors which
cannot be built into this product, but must be
supplied by the operator.

Battery Charger Safety
1. SAVE THESE INSTRUCTIONS - This manual
contains important safety and operating instruction
for battery charger Model U1BR21103.
2. Before using battery charger, read all instructions
and cautionary markings on battery charger,
battery, and product using battery.
3. CAUTION - To reduce risk of injury, charge only
li-ion type rechargeable batteries. Other types of
batteries may burst causing personal injury and
damage.
4. Do not charge or use appliance in rain, or in wet
locations.
5. Do not use battery-operated appliance in rain.
6. Remove or disconnect battery after use, before
servicing, cleaning or removing material from
the gardening appliance.
7. Do not dispose of battery in a fire. The cell may
explode. Check with local codes for possible
disposal instructions.
8. Do not open or mutilate the battery. Released
electrolyte is corrosive and may cause damage to
the eyes or skin. It may be toxic if swallowed.
9. Exercise care in handling batteries in order not
to short the battery with conducting materials
such as rings, bracelets, and keys. The battery
or conductor may overheat and cause burns.
Vibration Safety
This tool vibrates during use.
Repeated or long-term exposure to vibration may cause
temporary or permanent physical injury, particularly to
the hands, arms and shoulders. To reduce the risk of
vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-ups to
ensure medical problems are not being caused or
worsened from use. Pregnant women or people
who have impaired blood circulation to the hand,
past hand injuries, nervous system disorders,
diabetes, or Raynaud’s Disease should not use this
tool. If you feel any symptoms related to vibration
(such as tingling, numbness, and white or blue
fingers), seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces the
blood supply to the hands and fingers, increasing
the risk of vibration-related injury.
3. Wear suitable gloves to reduce the vibration
effects on the user.
4.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
