Disposal
Most of the materials from which Hilti products are manufactured can be recycled. The materials must be
correctly separated before they can be recycled. In many countries, your old tools, machines or appliances
can be returned to Hilti for recycling. Ask Hilti Service or your Hilti representative for further information.
Drilling slurry
Disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable pretreatment
presents environmental problems.
▶ Ask the local public authorities for information about current regulations.
We recommend the following pretreatment:
▶ Collect the drilling slurry (for example, using a wet-type vacuum cleaner).
▶ Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site
(addition of a flocculent may accelerate the settling process).
▶ The remaining water (alkaline, pH value greater than 7) must be neutralized by the addition of an acidic
neutralizing agent or diluted with a large volume of water before it is allowed to flow into the sewerage
system.

Federal emission control warranty statement
Your warranty rights and obligations
The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Hilti are
pleased to explain the Emission Control System Warranty applicable to your small non-road engine. In U.S.
and Canada, small non-road engines must be designed, built and equipped to meet the stringent federal
antismog standards. The equipment engine must be free from defects in materials and workmanship which
cause it to fail to conform with U.S. EPA standards for the first two years from the date of sale to the ultimate
purchaser. Hilti must warrant the emission control system on your small non-road engine for the periods of
time listed above, provided there has been no abuse, neglect or improper maintenance of your unit. Your
emission control system includes parts such as the carburetor and the ignition system. Where a warrantable
condition exists, Hilti will repair at no cost to you. Expenses covered under warranty include diagnosis, parts
and labor.
Manufacturer's warranty coverage
All 2001 and later small non-road engines are warranted to meet the applicable EPA and CARB requirements
for two years. If any emission related part on your engine (as listed above) is defective, the part will be
repaired or replaced by Hilti.
Owner's warranty responsibilities
As a small non-road engine owner, you are responsible for performance of the required maintenance as
defined by Hilti in the owner's manual. Hilti recommends that you retain all receipts covering maintenance
on your small non-road engine, but Hilti cannot deny warranty solely for the lack of receipts or for your failure
to ensure the performance of all scheduled maintenance. Any replacement part or service that is equivalent
in performance and durability may be used in non-warranty maintenance or repairs, and shall not reduce the
warranty obligations of the engine manufacturer. As the small non-road equipment owner, you should be
aware, however, that Hilti may deny you warranty coverage if your small non-road engine or a part of it has
failed due to abuse, neglect, improper maintenance, unapproved modifications or the use of parts not made
or approved by the original equipment manufacturer. You are responsible for presenting your small non-road
engine to Hilti as soon as the problem exists. The warranty repairs should be completed in a reasonable
amount of time, not to exceed 30 days.
Coverage
Hilti warrants to the ultimate purchaser and each subsequent purchaser that your small non-road equipment
engine will be designed, built equipped, at the time of sale, to meet all applicable regulations. Hilti also
