MAINTENANCE
WEEKLY MAINTENANCE (EVERY 40 HOURS)
The following table tells you where to look in the manual to find procedures for specific occasional maintenance
tasks:
3. CLEANING
Daily cleaning of the sweeper is a major factor in keeping it operating at its peak performance level. Dirt and
grime are always easier to remove before they have a chance to build up and bond to the sweeper surfaces.
When the components on the sweeper are not cleaned regularly, debris collects and adheres rapidly. This
decreases the air flow, blocks the water nozzles and causes unnecessary wear. Component life will be
maximized by cleaning the sweeper as often as possible.
Spray wash the outside and underside of the sweeper and truck cab to remove rust causing road grime that is
harmful to the painted surfaces. Clean out the truck cab and remove any objects not required during sweeping
operations. Also make sure that windows and mirrors are clean for maximum visibility.
At the end of each work shift, dump the hopper and wash it out. This will prevent corrosive road salts and
organic acids contained in debris from prematurely rusting the inside of the hopper raised an inch or two so the
pressure against the fan and intake seals has been relieved and they may regain their shapes.
4. SWEEPER FLUID MAINTENANCE
Component
Maintenance
Fan Housing Liner
Check for wear and replace at first sight of holes.
Fan Housing Liner Bolts
Check heads for wear and replace as needed.
Fan
Check for wear and replace if blades are worn through
Water system
Drain water reservoir. Remove and clean water filter.
4.3 Cleaning
4.1 Hydraulic System
The hydraulic oil level should be maintained such that it is
kept at the full mark as measured with the hopper down.
Check by using the sight level gauge, which is located on
the left side of the reservoir. Change the hydraulic oil and
filter after the first 500 hours of operation, then every 2000
hours thereafter.
If the hydraulic fluid becomes cloudy, water has
contaminated the system and the hydraulic fluid needs to be
changed (after determining the source of the water
contamination and correcting it). If the sweeping unit is
operated in particularly dusty conditions, the hydraulic filters
will need to be changed more often.
4.4 Hydraulic System
Check for wear and fi ll holes or cuts with RTV silicone rubber or place as
needed.
Drain water reservoir during freezing temperatures. Remove and clean water
fi lter. Remove and clean nozzle tips and tip fi lters.
At the end of each work shift, dump the hopper and wash it out. This wil prevent corrosive road salts and organic acids contained in
debris from prematurely rusting the inside of the hopper. Raise the hopper an inch or two so the pressure against the fan and intake
seals has been relieved and they may regain their shapes.
Full Mark
The sweeper comes with an oil additive to aid in detection of leaks. This
additive can be easily seen with the use of an UV light.
