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.

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.

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.

The fitting procedure is the reverse of the removal procedure.

Use new “O” ring flares.
