MAINTENANCE
Figure 4-A
Engine Water Separator
WARNING: Do not inhale ether
fumes. They are extremely harmful.
Do not spray excessive amounts
(two seconds per time) of ether
starting fluid when starting the
engine. Using too much ether will
cause engine damage.
If the unit is equipped with an Automatic Ether
Injection System, use the following described
steps for starting in cold weather.
A. Put unit in neutral and set parking brake.
B. Set throttle to idle.
C. While cranking the engine, inject a metered
amount of ether starting fluid by pushing the Ether
Injection button.
D. Be sure the engine oil pressure is indicated
on the gauge within 30 seconds after starting.
E. Never inject ether for more than two (2)
seconds at a time.
Fuel Filter and Water Separator
Diesel engine injection systems use fuel for
lubrication of close tolerance internal engine parts.
Proper maintenance of the fuel filters and the fuel
tank are required for continued top performance
and to prevent damage to internal engine
components.
The engine fuel filter and water separator are
located on the left side of the engine. A drain
valve is provided on the bottom of the water
separator (Figure 4-A).
A. Before operating the engine, use the valve
to drain a small quantity of fuel from the water
separator into a clean, clear container. This is an
absolutely necessary daily routine.
B. If water or contaminants are found in the
fuel you drained, DO NOT attempt to start the
engine. Continue to drain fuel into the container
until it runs clear.
C. If large amounts of contamination are
found, drain the fuel tank until the lines run clear.
Replace the filters. Fill new filters with fresh clean
fuel and install.
The manufacturer's diesel engine manual provided
with your broom contains more detailed
information on fuel system maintenance
procedures.
Crankcase Oil
A. Engine crankcase oil level should be
checked daily prior to each day's use of the
broom. The machine must be parked on a level
surface when checking the oil to assure accurate
measurements. When checking oil while the
engine is warm, wait until the engine has been
OFF for at least five minutes. This allows oil to
drain back to the crankcase.
