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).
Maintenance
Service
Service of a tool requires extreme care and knowledge.
Service should be performed only by a qualified service
technician.
• Always check tool for damaged parts before use.
• Replace or repair damaged parts before use. Check
alignment of moving parts. Binding of moving parts or
broken parts may alter operation.
• Have damaged parts properly repaired or replaced by an
Authorized Service Center.
• Do not use tool if switch does not turn it on and off.
• Maintain tools. Keep tools dry, clean and free of oil and
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.
• Use safety equipment. Always wear eye protection.
