8.1 GENERAL
This Jet Unit has been designed to require the
absolute minimum of maintenance. However it is
recommended that the Jet Unit be regularly
examined for the wear of the Bearings, Seals and
Bushes, etc and checked for corrosion anually as a
minimum requirement.
HYDRAULIC EQUIPMENT:— When servicing
Hydraulic Equipment, use the following general
rules to ensure effective and trouble free servicing:
1. Minimise the loss of oil to surrounding areas by
liberal use of oil absorbent cloth.
2. If disconnecting hydraulic connections to
components which are not going to be serviced
immediately, plug the connection to prevent loss
of oil and entry of foreign particles.
8.2 PRESERVATION: (PRE-
INSTALLATION)
NEW JET PRESERVATION:— The following storage
requirements must be provided to ensure that no
damage or deterioration occurs:
1. Temperature must be between 10ºC and 40ºC
and above the "dew point" (i.e. No condensation
is allowed to form).
2. It is desirable to keep the Bearing Housing
components coated with grease. Turn the
Mainshaft 180º once every month to achieve
this.
3. All exposed steel parts (except for stainless steel
parts) should be protected from corrosion. As a
corrosion preventative treatment, coat all
exposed steel parts with a thin layer of rust
preventative oil.
4. To protect hydraulic fittings, either:
a) Coat with oil impregnated corrosion
protection tape,
OR
b) Spray with a recognised corrosion protection
treatment.
PREPARATION FOR USE:— To prepare the Jet Unit
for use:
Ensure that the Bearing Housing is greased via the
grease nipple on the top of the Bearing Housing.
Refer to Section 9.6.3 Re-Assembly of the Bearing
Housing .
