MAINTENANCE

To avoid serious 

personal injury, always remove the battery 
pack from the Power Source when 
cleaning or performing any maintenance. 
Never disassemble the power source, 
battery pack or charger. 

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.

To reduce the risk of 

personal injury and damage, never immerse 
your tool, battery pack or charger in liquid  
or allow a liquid to flow inside them.

When servicing, use 

only identical replacement parts. Use of any 
other parts may create a hazard or cause 
product damage. To ensure safety and 
reliability, all repairs should be performed 
by a qualified service technician.
