.
2. The oil is at the correct level when it reads
between the full mark and the lower end of the
dipstick. If capacity is low, add ISO VG 46
hydraulic oil through the combined
dipstick/filler plug. Do not overfill the reservoir.
3. Reinstall the dipstick/filler plug.
Changing the Power Steering Oil
NOTE: Change the power steering oil/filter after
every 600 hours of operation.
1.
Place a suitable container beneath the power
steering reservoir to catch the used oil. With
the oil at normal operating temperature, drain
the power steering reservoir by removing the
drain plug that located at bottom of filter
flange. Reinstall the plug once the oil has
drained and discard the used oil.
2.
Rotate counter-clockwise to remove the filter/
reservoir assembly.

Coat the gasket on the new filter with a film of
clean oil. Screw the filter into place until the
gasket contacts the sealing surface, then
tighten the filter by hand approximately
three-quarters of a turn. Do not over-tighten.
4.
Remove the filler plug/dipstick and fill with ISO
VG 46 hydraulic oil. The oil reservoir is filled
to the correct level when the level reads
between the full mark and the lower end of the
dipstick. Do not fill above the full mark.
