The hydraulic fluid filter is located in front of the
hydraulic reservoir near the rear of the engine
compartment. Replace the filter element after
every 1200 hours of operation or if the clogged
hydraulic filter light remains on. Check the
hydraulic fluid level and refill as needed.

If using a locally
−
available hydraulic fluid, be sure
the specifications match the Tennant hydraulic
fluid specifications. Substitute fluids can cause
premature failure of hydraulic components.
ATTENTION! Hydraulic components
depend on system hydraulic fluid for
internal lubrication. Malfunctions,
accelerated wear, and damage will result
if dirt or other contaminants enter the
hydraulic system.
