WARNING

CALIFORNIA

Proposition 65 Warning

This product contains a chemical or chemicals

known to the State of California to cause cancer,

birth defects, or reproductive harm.

General Safety Rules

Model 51889T does not include a battery or a charger.

WARNING: When using electric power tools, basic safety
precautions should always be followed to reduce the risk of fire,
electric shock, and personal injury, including the following:

Read all instructions.

The term “power tool” in all of the warnings refers to your
mains-operated (corded) power tool or battery-operated (cordless)
power tool.

1.

Work area safety

A.

Keep work area clean and well lit.

Cluttered or dark

areas invite accidents

B.

Do not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust.

Power tools create sparks

which may ignite the dust or fumes.

C.

Keep children and bystanders away while operating
a power tool.

Distractions can cause you to lose

control.

2.

Electrical safety

A.

Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools

.

Unmodified plugs and matching outlets will reduce risk
of electric shock.

B.

Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.

There is an increased risk of electric

shock if your body is earthed or grounded.

C.

Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of
electric shock.

D.

Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts

.

Damaged or entangled cords increase

the risk of electric shock.

E.

When operating a power tool outdoors, use an
extension cord suitable for outdoor use.

Use of a

cord suitable for outdoor use reduces the risk of electric
shock

.

F.

If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply.

Use of an RCD reduces the risk of

electric shock.

3.

Personal safety

A.

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.

B.

Use personal protective equipment. Always wear
eye protection.

Protective equipment such as dust

mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.

C.

Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool.

Carrying power tools with your finger on the

switch or energizing power tools that have the switch
on invites accidents.

D.

Remove any adjusting key or wrench before turning
the power tool on.

A wrench or a key left attached to

the power tool may result in personal injury

.

E.

Do not overreach. Keep proper footing and balance
at all times.

This enables better control of the power

tool in unexpected situations.

F.

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.

G.

If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
