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.  

MAKITA LIMITED ONE YEAR WARRANTY

Warranty Policy

Every Makita tool is thoroughly inspected and tested before leaving the factory.  It is warranted to be free of 
defects from workmanship and materials for the period of ONE YEAR from the date of original purchase.  
Should any trouble develop during this one year period, return the COMPLETE tool, freight prepaid, to one of 
Makita’s Factory or Authorized Service Centers. If inspection shows the trouble is caused by defective 
workmanship or material, Makita will repair (or at our option, replace) without charge.

This Warranty does not apply where:

• repairs have been made or attempted by others:

• repairs are required because of normal wear and tear:

• the tool has been abused, misused or improperly maintained:

• alterations have been made to the tool.

IN NO EVENT SHALL MAKITA BE LIABLE FOR ANY INDIRECT, INCIDENTAL OR CONSEQUENTIAL 
DAMAGES FROM THE SALE OR USE OF THE PRODUCT.  THIS DISCLAIMER APPLIES BOTH DURING 
AND AFTER THE TERM OF THIS WARRANTY.

MAKITA DISCLAIMS LIABILITY FOR ANY IMPLIED WARRANTIES, INCLUDING IMPLIED WARRANTIES OF 
“MERCHANTABILITY” AND “FITNESS FOR A SPECIFIC PURPOSE,” AFTER THE ONE YEAR TERM OF THIS 
WARRANTY.

This Warranty gives you specific legal rights, and you may also have other rights which vary from state to state.  
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above 
limitation or exclusion may not apply to you.  Some states do not allow limitation on how long an implied 
warranty lasts, so the above limitation may not apply to you.
