Protecting the Environment
 Separate collection. This product must not be disposed of with 
normal household waste.
Should you find one day that your DEWALT product needs replacement, or 
if it is of no further use to you, do not dispose of it with household waste. 
Make this product available for separate collection.
  Separate collection of used products and packaging allows 
materials to be recycled and used again. Re-use of recycled 
materials helps prevent environmental pollution and reduces the 
demand for raw materials. 
Local regulations may provide for separate collection of electrical products 
from the household, at municipal waste sites or by the retailer when you 
purchase a new product. 
DEWALT provides a facility for the collection and recycling of DEWALT 
products once they have reached the end of their working life. To take 
advantage of this service please return your product to any authorised 
repair agent who will collect them on our behalf.
