General Power Tool
Safety Warnings
WARNING Read all safety
warnings and instructions.
Failure to follow the warnings and
instructions may result in electric
shock, re and/or serious injury.
Save all warnings and
instructions for future reference.
The term ″power tool″ in the
warnings refers to your mains-
operated (corded) power tool or
battery-operated (cordless) power
tool.
Work area safety1.
Keep work area clean and well lit. a.
Cluttered or dark areas invite acci-
dents.
Do not operate power tools in b.
explosive atmospheres, such as in
the presence of ammable liquids,
gases or dust. Power tools create
sparks which may ignite the dust or
fumes.
Keep children and bystanders c.
away while operating a power tool.
Distractions can cause you to lose
control.
Electrical safety2.
Do not expose power tools to rain a.
or wet conditions. Water entering
SKU 99760 For technical questions, please call 1-800-444-3353. Page 3
a power tool will increase the risk of
electric shock.
Do not abuse the Power Cables. b.
Never use the cables for carrying
or pulling the power tool. Keep
cables away from heat, oil, sharp
edges or moving parts. Damaged
or entangled cables increase the risk
of electric shock.
Personal safety3.
Stay alert, watch what you are do-a.
ing and use common sense when
operating a power tool. Do not use
a power tool while you are tired
or under the inuence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
Use personal protective equip-b.
ment. Always wear eye protection.
Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or
hearing protection used for appropri-
ate conditions will reduce personal
injuries.
Prevent unintentional starting. c.
Ensure the switch is in the off-po-
sition before connecting to power
source and/or battery,
Do not overreach. Keep proper d.
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
Dress properly. Do not wear loose e.
clothing or jewelry. Keep your
hair, clothing and gloves away
from moving parts. Loose clothes,
jewelry or long hair can be caught in
moving parts.
Only use safety equipment that f.
has been approved by an appropri-
ate standards agency. Unapproved
safety equipment may not provide
adequate protection. Eye protection
must be ANSI-approved and breath-
ing protection must be NIOSH-ap-
proved for the specic hazards in the
work area.
Power tool use and care4.
Do not force the power tool. Use a.
the correct power tool for your ap-
plication. The correct power tool will
do the job better and safer at the rate
for which it was designed.
Do not use the power tool if the b.
switch does not turn it on and off.
Any power tool that cannot be con-
trolled with the switch is dangerous
and must be repaired.
Disconnect the Power Cables c.
from the power source and/or the
battery before making any adjust-
ments, changing accessories, or
storing power tools. Such preven-
tive safety measures reduce the risk
of starting the power tool accidentally.
Store idle power tools out of the d.
reach of children and do not allow
persons unfamiliar with the power
tool or these instructions to oper-
ate the power tool. Power tools are
dangerous in the hands of untrained
users.
Maintain power tools. Check for e.
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation. If dam-
aged, have the power tool repaired
before use. Many accidents are
caused by poorly maintained power
tools.
SKU 99760 For technical questions, please call 1-800-444-3353. Page 4
Use the power tool in accordance f.
with these instructions, taking into
account the working conditions
and the work to be performed. Use
of the power tool for operations differ-
ent from those intended could result
in a hazardous situation.
Battery tool use and care5.
Under abusive conditions, liquid a.
may be ejected from the battery;
avoid contact. If contact acciden-
tally occurs, ush with water. If
liquid contacts eyes, additionally
seek medical help. Liquid ejected
from the battery may cause irritation
or burns.
Service6.
Have your power tool serviced by a.
a qualied repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.

mable liquids with this tool. This tool
is designed to pump diesel fuel or
light oil only.
Maintain labels and nameplates on 2.
the tool. These carry important safety
information. If unreadable or miss-
ing, contact Harbor Freight Tools for a

When using a handheld power tool, 4.
maintain a rm grip on the tool with
both hands to resist starting torque.

consult their physician(s) before use.
Electromagnetic elds in close prox-
imity to heart pacemaker could cause
pacemaker interference or pacemak-
er failure. In addition, people with
pacemakers should:
• Avoid operating alone.
• Do not use with power switch locked
on.
• Properly maintain and inspect to
avoid electrical shock.
• Any power cord must be properly
grounded. Ground Fault Circuit Inter-
rupter (GFCI) should also be imple-
mented – it prevents sustained elec-
trical shock.
