Lubricate the filler cap gasket with a film of
hydraulic fluid before putting the cap back on the
reservoir.
Do not overfill the hydraulic fluid reservoir. The
hydraulic fluid expands as it heats to its normal
operating temperature. Always allow for
expansion when filling the reservoir.
ATTENTION! Do not overfill the
hydraulic fluid reservoir or operate the
machine with a low level of hydraulic
fluid in the reservoir. Damage to the
machine hydraulic system may result.
Drain and refill the hydraulic fluid reservoir with
new Tennant True premium hydraulic fluid after
every 2400 hours of operation. Machines have a
blue colored drop (left photo) on the hydraulic fluid
label if originally equipped with Tennant True
premium hydraulic fluid.
