HYDRAULICS
HYDRAULIC FLUID RESERVOIR
The reservoir is located in the engine
compartment next to the radiator.
Mounted on top of the reservoir is a filler cap with
a fluid level dipstick. The reservoir also has a
hydraulic breather. On machines below serial
number 003219, the breather is built into the filler
cap. On machines serial number 003219 and
above, the breather is located next to the filler
cap. Replace the hydraulic breather after every
800 hours of operation.
Check the hydraulic fluid level at operating
temperature every 100 hours of operation. Make
sure the hopper is down when checking hydraulic
fluid level. The end of the dipstick is marked with
FULL and ADD levels to indicate the level of
hydraulic fluid in the reservoir.
Lubricate the filler cap gasket with a film of
hydraulic fluid before putting the cap back on 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 hydraulic fluid every 800 hours of operation.
The hydraulic fluid filter is located at the bottom of
the engine compartment. Replace the filter
element every 800 hours of operation.
The reservoir has a built-in strainer outlet that
filters hydraulic fluid before it enters the system.
Replace the strainer every 800 hours of operation.
HYDRAULIC FLUID
The quality and condition of the hydraulic fluid
play a very important role in how well the machine
operates. TENNANT’s hydraulic fluid is specially
selected to meet the needs of TENNANT
machines.
