When servicing, use only identical 

Craftsman replacement parts. Use of any other part 
can create a hazard or cause product damage.

WARnInG: 

Always wear eye protection with side 

shields marked to comply with ANSI Z87.1. Failure to 
do so could result in objects being thrown into your 
eyes, resulting in possible serious injury.

WARnInG: 

To avoid serious personal injury, always 

remove the battery pack from the tool when cleaning 
or performing any maintenance. 

Avoid using solvents when cleaning plastic parts. Most 
plastics are susceptible to damage from various types of 
commercial solvents and may be damaged by their use. 
Use clean cloths to remove dirt, dust, oil, grease, etc.

WARnInG: 

Do not at any time let brake fluids, 

gasoline, petroleum-based products, penetrating 
oils, etc. come in contact with plastic parts. Chemi-
cals can damage, weaken or destroy plastic which 
can result in serious personal injury.

Only the parts shown on the parts list are intended to be  
repaired or replaced by the customer. All other parts 
should be replaced at a Sears Service Center.

Upon removal, cover the battery pack’s 

terminals with heavy-duty adhesive tape. Do not 
attempt to destroy or disassemble battery pack 
or remove any of its components. Lithium-ion and 
nickel-cadmium batteries must be recycled or dis-
posed of properly. Also, never touch both terminals 
with metal objects and/or body parts as short circuit 
may result. Keep away from children. Failure to 
comply with these warnings could result in fire and/
or serious injury.
