STARTING UP AND STOPPING THE ENGINE

 

 
The minitransporter is powered by an endothermic engine. By way of example, a synthesis 
of the engine user's manual is reported below.  
 

For further details, see the user's manual for the engine installed in the machine.  

 
The engine is started up with a self-winding starter. 
 
Before  starting  up  the  engine,  check  that  the  machine  is  in  perfect  condition  and,  in 
particular, check the following: 
 
Check that all fluids are up to level (engine oil, hydraulic oil and fuel). 
 
Check that there is no carryover of liquid from the fuel feed circuit and hydraulic oil circuit 
or from other elements in an oil bath. 
 
Check that none of the hydraulic hoses are damaged, worn or burnt. 
 
Check that there are no foreign bodies in the tracks and other machine parts.  
 
Check that the degree of wear on the tracks permits use of the machine.  
 
Check  that  none  of  the  sheaths  on  the  electrical  cables  are  damaged  or  worn  and  that 
none of the cables are burnt.  
 
Moving the machine control levers, check that there is no gripping or seizing of the various 
tools.  
If one of the above controls gives a negative result, eliminate the problem and repair the 
element,  working  independently  if  the  operations  involved  are  covered  in  this  manual.  If 
not, contact an authorized service center to perform any other operations.  
 
Before starting up the engine, set the accelerator lever at its midpoint.  
 
Once the engine has been started up, let it idle for approximately 1 minute so that the oil 
can reach all lubrication points and that the hydraulic oil powers the various users. For the 
following 5 or 10 minutes, operate accelerating slowly. Only after this time has elapsed is 
the machine ready for full operation.  
 
N. B. The engines are built to operate even if they are exposed to the weather (machines 
without  hood).  Nevertheless,  in  order  to  prevent  rapid  oxidation  of  ferrous  parts 
(conveyors,  flywheels,  self-winding  spring,  etc.),  if  the  machine  is  to  remain  unused  for 
long periods of time (a few hours) in the rain or snow, it is advisable to protect the engine 
with a tarpaulin and remove it

 before starting to wor

k

.

 

 

 
For  details  on  the  operations  required  to  start-up  and  shutdown  the  engine,  follow  the 
instructions given below. 

 

 
WARNING! 

ENGINE REQUIRES LEAD-FREE GASOLINE
