Place your hand
near the connection to sense for heat
before
touching the connection. If hot, allow the hydraulic
system to cool down before touching the heated
connections.
Hydraulic pumps and control valves operate
with minute
clearances (tolerances). Grit,
grime and dirt pushed through these openings
can eventually wear the surfaces and damage
the system. Clean hydraulic oil must be used.
The fill area and connections must be kept
clean as well.
Dirt is the greatest source of hydraulic system
damage.
Filter element replacement
: remove the top cover on the
filter body and using the handle on top of the filter remove
from the filter body. Replacement is a reversal of removal.
Looking after the hydraulic oil is very important, keeping
the oil free from contamination will reduce the need to
change the oil. If you need to change the oil you can drain
the oil through the feed pipe to the pump. Remove the pipe
from the pump and drain into a suitable container, if you
are replacing the oil
then replacement of the filter element
is also required. Replace the pipe and filter before refilling
the tank. Check the oil level once it has been run and top
up as required.
