Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
Personal safety
1. Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the influence of drugs, alcohol or
medication. A moment of inattention while operating
power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear
eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate
conditions will reduce personal injuries.
3. Prevent unintentional starting.
Ensure the Power Switch is in the off-position
before connecting to power source, picking up or
carrying the tool.
Carrying power tools with your finger on the
Power Switch or energizing power tools that
have the Power Switch on invites accidents.
4. Remove any adjusting key or wrench
before turning the power tool on.
A wrench or a key left attached to a rotating part
of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
6. Dress properly. Do not wear loose 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.
7. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
8. Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be
ANSI-approved and breathing protection
must be NIOSH-approved for the
specific hazards in the work area.

Power tool use and care
1. Do not force the power tool. Use the
correct power tool for your application.
The correct power tool will do the job better and
safer at the rate for which it was designed.
2. Do not use the power tool if the Power Switch
does not turn it on and off.
Any power tool that cannot be controlled with the
Power Switch is dangerous and must be repaired.
3. Disconnect the battery pack from the
power tool before making any adjustments,
changing accessories, or storing power
tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Use clamps or another practical way to secure
and support the work piece to a stable platform.
Holding the work by hand or against your body
leaves it unstable and may lead to loss of control.
5. Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions
to operate the power tool. Power tools are
dangerous in the hands of untrained users.
6. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
7. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
8. Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
1. Recharge only with the charger specified by
the manufacturer. A charger that is suitable
for one type of battery pack may create a risk
SAFETYOPERATIONMAINTENANCESETUP
of fire when used with another battery pack.
2. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
3. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
4. Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the
battery may cause irritation or burns.
Service
Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
Multi-function Tool Safety Warnings
1. Hold power tools by insulated gripping
surfaces when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a ″live″ wire will make exposed metal
parts of the tool ″live″ and shock the operator.
2. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
3. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
4. Do not lay the tool down until it has come to
a complete stop. Moving parts can grab the
surface and pull the tool out of your control.
5. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.
7. 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.
8. This product is not a toy.
Keep it out of reach of children.
6. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
