MAINTENANCE
Your DeWALT power tool has been designed to 
operate over a long period of time with a minimum 
of maintenance. Continuous satisfactory operation 
depends upon proper tool care and regular cleaning.
   WARNING: To reduce the risk of 
injury, turn unit off and disconnect 
machine from power source before 
installing and removing accessories, 
before adjusting or changing set-
ups or when making repairs. Be sure 
the trigger switch is in the OFF position. 
An accidental start-up can cause injury.
  •  This machine is not user-serviceable. Take the 
tool to an authorised DeWALT repair agent after 
approximately 40 hours of use. If problems 
occur before this time contact an authorised 
DeWALT repair agent.
  •  The tool will automatically switch off when the 
carbon brushes are worn.
Motor Brushes
DeWALT uses an advanced brush system which 
automatically stops the drill when the brushes wear 
out. This prevents serious damage to the motor. 
New brush assemblies are available at authorised 
DeWALT service centers. Always use identical 
replacement parts.
Lubrication
Your power tool requires no additional lubrication.
Accessories and attachments used must be 
regularly lubricated around the SDS Plus fitment.
