7-16 Rosco Maximizer 3B Asphalt Distributor
Maintenance
7. Store the unit where it will be protected from
adverse weather conditions. All replacement parts,
whether complete assemblies, component repair
parts or service kits should be stored in a dry
sheltered area.
8. Fill the pump and spraybar with solvent (see Clean-
out Mode in Section 6).
9. If a unit will not be used for more than two months,
(see Maintenance Intervals Chart in Section 7).
Follow the procedure for the monthly interval, as
well as these preventative maintenance procedures:
Check for Water in Hydraulic Fluid - Any machine that
is stored for an extended period in a climate that has a
wide range of temperatures and/or humidity, will develop
condensation on the inside of the tank walls. Check the
hydraulic uid on a regular basis for possible moisture
contamination.
Hydraulic oil that is contaminated,
must be drained, the î›™lter elements replaced and the
tank relled with Rosco approved uid. Failure to do
this could result in premature failure of the pumps
and/or motors.
Warm-up and Cycling - Start and run the engine until it
is warm. Cycle all hydraulic and/or hydrostatic functions
until all components are warm and the hydraulic uid is
up to operating temperature.
Lubrication - After the machine is warmed up, grease all
pivot points.
Protection of Exposed Cylinder Rods - During periods
of extended storage, (two months or longer), retract all
cylinder rods as far as possible. Coat with grease any
exposed part of the cylinder rod, to prevent rusting. Any
stored cylinders, all exposed seals, o-rings, etc. should
be coated with grease to prevent cracking.
Daily Exterior
Maintenance
Clean the top platform, steps, railings, ladder and
catwalk to prevent accidents during operation. Clean
the instruction plates, decals and gauges so they can
be seen and read by the operator at all times. Replace
any decals or information plates that are damaged or
illegible. Clean all lights and reectors so they can be
seen by other vehicles.
Storage
Do not store equipment where it is
subjected to damage from dirt and weather.
A stored machine requires as much periodic
maintenance as a machine at work. Stored units
must receive periodic scheduled maintenance. Many
instances of customer downtime and dissatisfaction
can be traced to parts that became defective due to
inattention during storage.
The following procedures will help maintain equipment
and lessen downtime:
1. Thoroughly clean the unit as you would at the end
of the day. Be sure there is no asphalt in the tank,
pump or piping. Use (see Maintenance Intervals
Chart in Section 7) to check and/or clean every
component listed.
2. Replace any worn or damaged parts. Touch up any
scratched or chipped painted surfaces.
3. Lubricate all grease points. Make sure all grease
cavities have been î›™lled with grease.
4. Top up all uid levels to minimize condensation
during storage.
5. Inspect all air and hydraulic hoses, couplers, î›™ttings
and cylinders. Tighten any loose î›™ttings and replace
any hoses that are worn.
6. Check all safety decals. Replace any decals that are
damaged or illegible.
