SAFETYOPERATIONMAINTENANCE SETUP
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
use in areas where they may be present.
5. Do not pick up anything that is burning
or smoking, such as cigarettes,
matches, or hot ashes.
6. Remove all hard objects from work
area. Do 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
Harbor Freight Tools 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.

Lithium Battery Safety Warnings
LITHIUM BATTERIES STORE
A LARGE AMOUNT OF ENERGY AND
WILL VENT FIRE OR EXPLODE IF MISTREATED:
1. Keep Battery Pack dry.
2. DO NOT DO ANY OF THE FOLLOWING
TO THE BATTERY PACK:
a. Open,
b. Drop,
c. Short-circuit,
d. Puncture,
e. Incinerate, or
f. Expose to temperatures greater than 104°F.
3. Charge Battery Pack only according
to its Charger’s instructions.
4. Inspect Battery Pack before every use;
do not use or charge if damaged.
Battery Charger Safety
1. SAVE THESE INSTRUCTIONS - This manual
contains important safety and operating
instruction for battery charger Model 56416.
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. Use tools with the lowest vibration
when there is a choice.
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.
