Hydraulic Tank - Husqvarna ZTH5223 Workshop Manual

Hydraulic Tank

Draining
1. The drain cap (29) is located on the
underside of the tank in the front left
corner (see the "ZTH hydraulic system"
diagram). Drained hydraulic oil must be
handled in accordance with the
regulations governing the disposal of
waste oil. Do not put drained oil back into
the system.
2. It is not necessary to drain the entire
hydraulic system when performing
scheduled hydraulic system oil changes.
Change only the oil in the tank.
3. Anytime the hydraulic oil is changed, the
oil filter should also be changed.
Filling
Fill the tank with clean oil direct from the
manufacturer's container. For oil type, refer to
the hydraulic tank decal or the lubrication
chart. The use of non-approved oils can
invalidate the warranty.
The level must be around 19 - 25 mm (3/4" -
1") below the top of the tank. Vent the system
using the air screws on the hydraulic pumps
and top-up as necessary.
Removing
1. Drain the hydraulic tank as above.
2. Disconnect the 7" tube (25) and "O" ring (33) from the tank.
3. Disconnect the hose (27) and "O" ring (33) from the tank.
4. Remove the bolts (10) - nuts located beneath the bracket - and their washers (13). Lift the tank
away.
Fitting
The fitting procedure is the reverse of the removal procedure.
Use new "O" ring flares.
