Safety Information :

This manual is furnished with your rotary blasthole drill to aid you in performing the necessary service work to maintain your drill in good operating condition. This manual contains repair and adjustment information for all major operating systems on the machine. In some cases such as hydraulic pumps and motors it is better to replace the unit with a new or rebuilt unit than to perform major repairs. Should further information be desired or should particular problems arise which are not covered sufficiently in this manual, the matter should be referred to manufacturer.

• The descriptions and specifications contained in this manual were in effect at the time of printing. The right is reserved to make changes at any time without notice and without obligation.
