Restarting After Running Out of Fuel
The 2011 series Deutz engines do not require bleeding of
the fuel system if the engine is run out of fuel.
To restart the engine:
1. Refill the fuel tank with fresh, clean diesel fuel.
2. Re-prime the fuel system by squeezing the fuel prime
bulb (located inside the console, directly under the fuel
tank), until the fuel primer bulb becomes firm.
3. Crank the engine normally until it starts.
OPERATING SYNOPSIS
BEFORE STARTING — Check all fluid levels. Secure blade

are in place and properly mounted. Wear eye, ear
protection and protective clothing.
WATER SUPPLY — Connect water supply to water inlet.
Move water ON/OFF CONTROL to ON position. Adjust
WATER FLOW CONTROL lever to desired position.
Drain watering system in cold weather to prevent
damage due to freezing.
BLADES — Always follow blade manufacturer’s
recommendations for blade selection, speed and
application. NEVER exceed blade manufacturer’s
