The scrapers must be lifted from the drum during 
transport. 

 

Brakes 

Run the roller very slowly forward. Hold the 
steering wheel firmly and brace yourself for a 
sudden stop. Press in the emergency stop. The 
roller will stop abruptly and the engine will switch 
off. After testing the brakes, set the forward/ 
reverse lever in neutral. Pull out the emergency 
stop. Start the engine. The roller is now ready for 
operation. 

Sprinkler  System 

Start the sprinkler system and make sure that 
nozzles are clogged. If necessary, clean 
clogged nozzles and the coarse filter located by 
the water pump. 

 

 

The  sprinkler  system  should  be  drained  if 

there  is  a  risk  of  freezing. 

Wear  protective  eye  glases  when  working 

with  compressed  air. 

 

Dismantle the blocked nozzle by hand. Blow the 
nozzle and fine filter clean with compressed air, or 
install replacement parts and clean the clogged 
parts later.
