Important Safety Instructions for All 

Battery Packs

WARNING:

Read all safety warnings, instructions, 

and cautionary markings for the battery pack, 

charger and product. Failure to follow the 

warnings and instructions may result in electric 

shock, fire and/or serious injury.

• 

Do not charge or use the battery pack in explosive 

atmospheres, such as in the presence of flammable 

liquids, gases or dust.

 Inserting or removing the battery 

pack from the charger may ignite the dust or fumes.

• 

NEVER force the battery pack into the charger. DO 

NOT modify the battery pack in any way to fit into a 

non‑compatible charger as battery pack may rupture 

causing serious personal injury. 

Consult the chart 

at the end of this manual for compatibility of batteries 
and chargers.

• 

Charge the battery packs only in

 chargers.

• 

DO NOT

 splash or immerse in water or other liquids.

• 

DO NOT

 allow water or any liquid to enter battery pack.

• 

Do not store or use the tool and battery pack in 

locations where the temperature may reach or 

exceed 104 °F (40 °C) (such as outside sheds or metal 

buildings in summer).

 For best life store battery packs in 

a cool, dry location.

NOTE: Do not store the battery packs in a tool with 

the trigger switch locked on. Never tape the trigger 

switch in the ON position.

• 

Do not incinerate the battery pack even if it is 

severely damaged or is completely worn out.

 The 

battery pack can explode in a fire. Toxic fumes and 
materials are created when lithium‑ion battery packs 
are burned.

• 

If battery contents come into contact with the skin, 

immediately wash area with mild soap and water. 

If 

battery liquid gets into the eye, rinse water over the open 
eye for 15 minutes or until irritation ceases. If medical 
attention is needed, the battery electrolyte is composed of a 
mixture of liquid organic carbonates and lithium salts.

Additional Safety Information

WARNING: 

Never modify the power tool or any part of 

it. Damage or personal injury could result.

WARNING: ALWAYS 

use safety glasses. Everyday 

eyeglasses are NOT safety glasses. Also use face or 
dust mask if cutting operation is dusty. ALWAYS WEAR 
CERTIFIED SAFETY EQUIPMENT:
•  ANSI Z87.1 eye protection (CAN/CSA Z94.3),
•  ANSI S12.6 (S3.19) hearing protection,
•  NIOSH/OSHA/MSHA respiratory protection.

WARNING: 

Some dust created by power sanding, 

sawing, grinding, drilling, and other construction 
activities contains chemicals known to the State 
of California to cause cancer, birth defects or 
other reproductive harm. Some examples of these 
chemicals are:
•  lead from lead‑based paints,
•  crystalline silica from bricks and cement and other 

masonry products, and

•  arsenic and chromium from 

chemically‑treated lumber.

Your risk from these exposures varies, depending on 
how often you do this type of work. To reduce your 
exposure to these chemicals: work in a well ventilated 
area, and work with approved safety equipment, such 
as those dust masks that are specially designed to filter 
out microscopic particles.

• 

Wear protective clothing and wash exposed areas 

with soap and water. 

Allowing dust to get into your 

mouth, eyes, or lay on the skin may promote absorption 
of harmful chemicals. Direct particles away from face 
and body.

• 

Use the appropriate dust extractor vacuum to remove 

the vast majority of static and airborne dust

. Failure 

to remove static and airborne dust could contaminate the 
working environment or pose an increased health risk to 
the operator and those in close proximity.

• 

Use clamps or other practical ways to secure and 

support the workpiece to a stable platform.

 Holding 

the work by hand or against your body is unstable and may 
lead to loss of control and injury.

• 

Air vents often cover moving parts and should be 

avoided.

 Loose clothes, jewelry or long hair can be caught 

in moving parts.

CAUTION: When not in use, place tool on its 

side on a stable surface where it will not cause 

a tripping or falling hazard. 

Some tools with large 

battery packs will stand upright on the battery pack 
but may be easily knocked over.
