Replacement Part List
Patented oil-injection system 
provides reliable performance. 
The no-mix system is an 
added convenience for 
operators. An amazing fuel 
to oil ratio of 120:1 allows 
for longer and cleaner 
running times... up 
to 100 hours on a 
single tank of oil. 
A low oil shutdown 
switch prevents running 
the rammer without 
oil. Exclusive air filter 
compensation system 
allows for longer run time 
between filter changes.
