Safety Messages
Snap-on Tools Company provides safety messages to
cover reasonable situations that may be encountered
when operating, servicing or repairing cordless tools. It
is the responsibility of operators and servicing
technicians to be knowledgeable about the procedures,
tools and materials used, and to satisfy themselves that
the procedures, tools and materials will not compromise
their safety, that of others in the work place or the tool.
General Power Tool
Safety Warnings
Read all safety warnings and all instructions. Failure to
follow the warnings and instructions may result in
electric shock, fire 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 safety
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• 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.
• Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
• 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.
• 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.
• Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
• 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.
• 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.
• If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of a RCD reduces the risk of
electric shock.
Personal safety
• 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.
• Use personal protective equipment. Always wear eye
protection. Personal protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
Power tool use and care
• Do not use the power tool if the switch does not turn it
on and off. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or 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.
• 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.
• 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.
Battery tool use and care
• Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with
another battery pack.

3
ZCTBTSR9050 (02/21)
• Use power tools only with specifically designated
battery packs. Use of any other battery packs may create
a risk of injury or fire.
• 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.
• 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.
Specific Safety Rules
• Hold power tool by insulated gripping surfaces, when
performing an operation where the fastener may
contact hidden wiring. Fasteners contacting a “live” wire
may make exposed metal parts of the power tool “live”
and could give the operator an electric shock.
Improper use of power tools and accessories can
cause broken tools.
• Read instructions before operating power tools.
• Be sure these instructions accompany the tool when
passed from one user to a new or inexperienced user.
• Do not remove any labels. Replace all damaged
labels.
Broken tools can cause injury.
Risk of contamination from hazardous dust.
• Wear an approved dust mask or respirator when using
power tools that create dust.
• Some dust created by power sanding, sawing,
grinding, drilling and other construction activities
contains chemicals known to cause cancer, birth
defects or other reproductive harm.
Inhaling hazardous dust can cause injury.
Power tools can cause flying particles during use.
Wear safety goggles, user and bystanders.
Flying particles can cause injury.
Power tools generate noise.
Wear hearing protection, user and bystanders.
Prolonged exposure to noise can cause hearing loss.
Power tools vibrate.
• Avoid prolonged exposure to vibration, repetitive
motions and uncomfortable positions.
• Stop using the tool if discomfort, tingling feeling or pain
occurs. Seek medical advice before resuming use.
Prolonged exposure to vibration, repetitive motions and
uncomfortable positions can cause injury.
Sudden changes in motion or position can occur
while using the tool.

Battery Pack Protection
To maximize performance and battery life, the Lithium-
Ion battery’s protection circuit monitors battery voltage,
discharge amperage and temperature. When the battery
voltage falls below the usable range, the battery will shut
off, and the 1st LED will flash for ten (10) seconds. The
battery needs charging. If the battery’s discharge
amperage limit is reached, due to excessive load, the
protection circuit will shut down the tool and the
illumination LED will remain on until the trigger is
released. Tool operation can be resumed immediately.
Cold Weather Operation
The Lithium-Ion battery can be used in temperatures
down to -4°F(-20°C). When the battery pack is very cold,
run the tool at no load to warm battery and then use the
tool normally.
Hot Weather Operation
If the Lithium-Ion battery temperature reaches
158°F(70° C), the protection circuit will turn off the
battery and all four LED’s will flash for four (4) minutes.
Once the battery has cooled down below 149°F(65°C),
the battery will resume normal operation.
Storage
Do not expose your battery pack to water or rain; this
could damage the battery pack.
Fully charge the battery before placing it in storage. For
optimum life, store the all Lithium-Ion batteries at room
temperature away from moisture. Permanent capacity
loss can result if batteries are stored for a long period at
high temperature, over 120°F(49°C).

grease for better and safer performance.
• For the location of the nearest Snap-on repair center,
call Snap-on customer service at 1-877-762-7664.
• When charging or discharging a lithium-ion battery over
a short period of time, the internal temperature of the
battery pack increases substantially. This is normal.
• Under ideal working conditions the useful life of a lithium-
ion battery pack is around 1000 charge/discharge cycles.
Improper care and maintenance shortens battery life and
the amount of time the battery holds a charge.
• Use only with Snap-on charging equipment that
specifies a CTB series battery pack.
• Avoid short circuiting the battery pack. Permanent
damage to the pack can occur from high current
discharge.
• Unplug charger from outlet before starting the
disassembly procedure.
• Remove the battery pack from the tool before starting
the disassembly procedure. Short-circuiting the
battery pack can cause fire or personal injury.
