◎Exchange
If the HST is operated for a long time, the HST oil will deteriorate and
foreign substances will settle inside the unit. To keep your work
safe and comfortable, change the HST oil regularly. Also, change
the HST oil filter (installed under the HST oil tank) at the same time
as changing the oil.
The total oil volume is 5.0L, and the hexagonal size of the HST oil plug
is 3/8 (inch). Change the HST oil within the first 30 hours, especially
when working in harsh environments. The metal powder inside the
HST unit may become clogged inside the oil filter, which may interfere
with running (especially during reverse travel).
1) At the time of product shipment, wear resistant hydraulic fluid equivalent to VG46 has
been added.
2) Please consult your dealer when replacing the HST oil. Replacement requires special tools
and maintenance skills.
HST designated oil: ISO viscosity grade VG46.
