MAINTENANCE
The suggestions and recommendations contained in this manual for maintenance should be
followed as closely as possible to obtain long life and best performance from your ROSCO
Broom.
PROPERLY MAINTAINED EQUIPMENT IS SAFE EQUIPMENT! The user of this product is
responsible for inspecting the broom daily, and for having parts replaced or repaired when
continued use of the machine would cause damage or excessive wear to other parts. General
daily inspection of the broom should include observation for missing guards, loose bolts, fluid
leaks, worn or damaged hoses and debris or dirt accumulations which could cause a potential
service or safety problem.
A PREVENTIVE MAINTENANCE CHART is included at the end of this section as a guide for
establishing a Preventive Maintenance Schedule.
ENGINE MAINTENANCE
In addition to the following maintenance recommendations, also consult the diesel engine
manufacturer's Operation & Maintenance Manual for detailed instructions. A copy of this manual was
provided with your ROSCO Broom at the time of its shipment from the factory. If additional copies are
needed, they can be obtained from your local authorized Rosco Dealer/Distributor or through a local
equipment dealer who sells or services the particular engine with which your broom is equipped.
Fuel Requirements
Use only clean, good quality ASTM No. 2-O or No.
2-D climatized diesel fuel. If the broom will be
used often in cold weather conditions (below 20°
F), blended fuels or No. 1 diesel fuel is
recommended to prevent gelling of the fuel filters.
The use of No. 1 diesel fuel may reduce the engine
performance by approximately 10%.
Avoid using contaminated fuel.
Fuel contaminated by water or
dirt can cause severe damage to
engine components. Fuel tanks
contaminated with water will
promote the growth of microbes
which form a "slime" that can
clog fuel filters and lines.
Cold Weather Starting
If it is necessary to use ether as a starting aid, do
it promptly. Read and follow the steps below and
the ether manufacturer's recommendations for
safe and effective use.
A. Place unit in neutral and set parking brake.
B. Set throttle to idle.
C. Have another person crank the engine
while you spray starting fluid into the air cleaner
for no more than two (2) seconds at a time.
Never remove the air filter element and spray
ether directly into the air inlet piping or the
intake manifold.
D. Be sure that engine oil pressure is
indicated on the gauge within 30 seconds after
starting.
DANGER: Never use ether near
open flames or with pre-heater or glo
plugs. The combination can cause
an explosion.
