Battery and Electrical System —————
To achieve maximum life and service from the battery, maintain the proper water level in cells and keep
terminals clean and free of corrosion. During the off season, remove battery from the sweeper and keep charged.
Fumes given off by the battery are explosive! Keep sparks and flames away from battery.
TO AVOID WELDER DAMAGE TO SENSITIVE ELECTRONIC COMPONENTS YOU
MUST ALWAYS:
1. Disconnect both Positive and Negative battery cables from the battery.
2. Disconnect the ground wire that attaches the ECM to the frame.
3. Attach welding ground clamp in close proximity to area being welded.
The electronic components on this engine and machine are very sensitive to stray electrical currents and can
incur serious damage if proper pre-cautions are not observed.
Air Cleaner —————
The air cleaner must be serviced periodically, depending on the dust conditions in which the engine is
being operated. The exhaust ejector removes a considerable amount of dirt from the air cleaner, and reduces the
frequency of service intervals. Always refer to the restriction indicator on the inlet side of the air cleaner as a
guide to determine service intervals. This “Informer” restriction indicator records the amount of restriction in the
element due to dirt inclusion. It is not recommended to service or replace the air cleaner element until the
restriction indicator shows an inlet restriction of 20 inches H

When cleaning this (conventional style) element, use caution so as not to damage the paper media or
sealing area, which could result in a “dusted” engine. Flory Industries recommends replacing the element
rather than servicing it. According to Donaldson, the filter dirt holding capacity is reduced 20-40% with each
cleaning, and Donaldson, like other heavy duty filter manufacturers, does not warrant the air filter once it has been
cleaned!
Flory Industries recommends Donaldson only for replacement elements! Warranty cannot be considered for
engine damage due to dust ingestion if a non-recommended element has been used in the air cleaner assembly!
Hydraulic System —————
It is recommended to change the hydraulic oil once every 500 hours or once per season. Change the suction
filter, located on the inside front of the oil tank, and the return filter located on the rear of the tank every 500 hours
also. See the Specifications and Fluids page at the back of this manual for hydraulic oil recommendation to
provide the best performance and life. Maintain the oil level within the sight gauge at all times.
Escaping hydraulic oil under pressure may penetrate the skin causing personal injury.
Before disconnecting any hydraulic lines, be sure to relieve the pressure. Periodically check
all lines and hoses to be sure they are not damaged.
