Preservation (Pre Installation) - Hamilton Jet HJ212 Installation And Service Manual

Installation and Service Manual
Application of Grey Gloss over existing Grey Gloss
The grey gloss top coat is based on polysiloxane technology. When applying grey gloss over existing grey
gloss (in sound condition), the existing paint requires abrading to provide a key for the new coating. A tie
coat is not used, as an epoxy tie coat is not recommended on a polysiloxane coating.
For touch up repairs to the grey gloss, Interfine 1080 or Interfine 878 may be used. Interfine 1080 is a single
pack product, which makes application more convenient. Interfine 878 is a two pack product that results in a
more durable finish than Interfine 1080. Interfine 878 is recommended where optimum paint durability is
required, and particularly for the waterjet internal water passages. Interfine 878 will provide faster drying
times than 1080.
Interfine 878 can be overcoated with Interfine 878 or Interfine 1080, however Interfine 1080 should only be
used for touch ups and Interfine 1080 can only be over-coated with Interfine 1080.

Preservation (Pre Installation)

New jet preservation:
Provide the following storage requirements to prevent damage or deterioration of the jet unit:
Temperature must be between 10ºC and 40ºC and above the "dew point" (i.e. no condensation is

allowed to form).
The bearing housing components should be kept coated with grease.

Rotate the mainshaft through several revolutions once a week.

Fill the bearing housing with the recommended lubricating grease via the grease nipple on the top of

the bearing housing to keep the bearings covered in grease. (This is more important in cold climates
where rusting due to condensation could occur).
Exposed steel parts (except for stainless steel)
Protect from corrosion by coating with a thin layer of rust preventative oil or

wrap with oil impregnated corrosion protection tape.
To protect hydraulic fittings, either:
Protect from corrosion by coating with a thin layer of rust preventative oil or

wrap with oil impregnated corrosion protection tape.
To prevent hydraulic seals bonding to shafts, operate the steering and reverse cylinders every 3 months.

Loosen the by-pass valves (where fitted) to allow manual movement of the cylinders.
Preparation for use
To prepare the jet unit for use:
Grease the bearing housing with a recommended grease.
