4.0 Tool Maintenance
4.1 Inspection
A thorough inspection should be
carried out prior to usage, storage or
transportation to ensure the completeness
and condition of the tool.
Inspection should include:
• Visual inspection of the outer parts of
the tool, checking for obvious damage,
degradation or missing parts.
• Visual inspection of the wedge-tip
(requiring tool actuation or jaw removal).
Damage to the wedge-tip is indicative
of tool over-load.
Cleaning and servicing should be
undertaken as required prior to the tool
being used, stored or transported.
4.2 Cleaning
To lightly clean the tool, wipe gently with
a damp cloth.
If more thorough cleaning is required (for
example following immersion in water)
carry out the following cleaning procedure:
• Strip the tool down.
• Clean the components using detergent,
following the manufacturer’s guidelines.
• Rinse the components to remove traces
of detergent.
• Dry the components thoroughly.
Inspect, service and lubricate the tool
immediately after the cleaning process.
4.3 Servicing
Replace missing worn or damaged parts.
Use only genuine Equalizer parts from
approved distributors or service centres.
Equalizer parts have been engineered and
manufactured to be fit-for-purpose.
Grease all moving parts by following the
Lubrication Procedure prior to usage,
storage or transportation.
If topping up or replacing hydraulic oil as
part of a service, use only premium quality
hydraulic oil of the grade 15 cSt.
4.4 Lubrication Procedure
Apply grease following cleaning and
servicing, prior to usage, storage or
transportation. Never assemble and leave
a tool without following the greasing
procedure as degradation or damage may
occur.
Use only high pressure molybdenum
disulphide grease.
Remove the jaws as per the disassembly
instructions.
Apply grease liberally to the following
areas:
• The large flat surface on the underside
of the jaws.
• The internal flat surfaces in the square
cut-out in the jaws.
4.5 Storage & Transportation
Equalizer tools should be stored in a
cool dry place. Tools should always be
cleaned, serviced and lubricated prior to
storage. Ensure that tools are stored in
their designated packing cases.
