Safety information 

 

The engine should only be installed and placed into operation by persons familiar with the use of 
the engine and informed with regard to possible hazards. 

 

Only ULPower authorized service centres are qualified to work on these engines. 

 

This engine is designed for possible application on aircraft used in VFR conditions which have the 
capabilities of controlled gliding without engine power. 

 

You  should  be  aware  that  any  engine  may  seize  or  stall  at  any  time.  This  could  lead  to  a  crash 
landing  and  possible  severe  injury  or  death.  For  this  reason,  we  recommend  strict  compliance 
with the maintenance and operation and any additional information which may be given to you by 
your dealer. 

 

Never  fly  the  aircraft  equipped  with  this  engine  at  locations,  airspeeds,  altitudes,  or  other 
circumstances  from  which  a  successful  no-power  landing  cannot  be  made,  after  sudden  engine 
stoppage. 

 

This engine is not suited for acrobatics (inverted flight, etc.). 

 

It should be clear that the choice, selection and use of this particular engine on any aircraft is at 
the  sole  discretion  and  responsibility  of  the  aircraft  manufacturer,  assembler  and  owner/user. 
ULPower  makes  no  warranty  or  representation  on  the  suitability  of  its  engine's  use  on  any 
particular  aircraft.  Furthermore,  ULPower  makes  no  warranty  or  representation  of  this  engine's 
suitability  with  any  other  part,  component  or  system  which  may  be  selected  by  the  aircraft 
manufacturer, assembler or user for aircraft application. 

 

Never run the engine without a propeller or flywheel as this will inevitably cause engine damage 
and present a hazard of explosion. 

 

Propeller/flywheel and its attachment with a moment of inertia in excess of the specified value 
must not be used and releases engine manufacturer from any liability. 

 

Improper engine installation and use of unsuitable piping for fuel-, cooling- and lubrication system 
releases engine manufacturer from any liability. 

 

Unauthorized  modifications  of  engine  or  aircraft  will  automatically  exclude  any  liability  of  the 
manufacturer for direct, indirect and/or sequential damage. 

 

Spare  parts  must  meet  with  the  requirements  defined  by  the  engine  manufacturer.  This  is  only 
warranted by use of genuine ULPower spare parts and/or accessories. They are available at the 
authorized ULPower distribution- and service partners. 

 

The use of anything other than genuine ULPower spare parts and/or accessories will render any 
warranty relating to this engine null and void. 

 

Respect  all  government  or  local  rules  pertaining  to  flight  operation  in  your  flying  area.  Fly  only 
when and where conditions, topography, and airspeeds are safest. 

 

Select  and  use  proper  and  calibrated  aircraft  instrumentation.  This  instrumentation  is  not 
included with the basic ULPower engine. 

 

Before flight, ensure that all engine controls are operative. Make sure all controls can be reached 
in case of an emergency. 

 

Unless in a run up area, never run the engine with the propeller turning while on the ground. Do 
not operate engine if bystanders are close. 

 

In the interest of safety, the aircraft must not be left unattended while the engine is running. 

 

Keep  an  engine  log  and  respect  engine  and  aircraft  maintenance  schedules.  Keep  the  engine  in 
top operating condition at all times. Do not operate any aircraft which is not properly maintained 
or has engine operating irregularities which have not been corrected.
