Destroyer Flail HD250F Flail Mulcher 

 
This manual contains the instructions for installation, use and maintenance of the Destroyer Flail HD250F Flail 
mulcher hereafter more simply called the ''Mulcher.'' 
 
The mulcher is designed and built to mulch branches, overgrown vegetation and trunks up to 30 cm in diameter. 
Any other use is deemed improper and, therefore, potentially dangerous for the safety of the operator or of any 
exposed persons. This manual is an integral part of the mulcher, defines the scope for which it was built, and 
contains all the information required for its proper and safe use. 
 
Regular machine operation depends on its correct use and adequate maintenance: it is advisable, therefore, to 
follow these instructions carefully to prevent any situation that could compromise 

the machine’s operation and 

durability. It is also important to follow that which is described in this manual since Spearhead declines any liability 
resulting from negligence of from not observing these norms, since it would result in the warranty being annulled. 
 
It is mandatory to verify upon delivery that the mulcher is integral and complete in all its parts. Any complaints must 
presented in written within 8 (eight) days from receiving the machine. Spearhead can however be contacted at any 
time for immediate and precise technical assistance and anything required for optimum operation and maximum 
performance of the equipment. Upon receiving the product, carefully read the manual and carefully follow the 
instructions contained in it.
