Suspension
Check the condition and operation of the springs. Check for signs of deformation or
cracking. If the springs show excessive corrosion (pitting or flaking of wire), or if springs
have taken a pre-compression set then they should be changed out. Springs can be
susceptible to yield over time. This can be verified by measuring the deflection of the
seat base in-situ. The following check is recommended to identify whether the springs
are fit for purpose:
In-situ spring check
The top of the sliding sleeve should rest against the compression
stop. If a space exists between the top of the sliding sleeve and the compression stops
greater than 10mm, then the spring should be replaced.
Check the spring cap plate for any signs of deformation.
8.
Frame and Buoyancy
Visually inspect for any damage and ensure that all bolts and fasteners are tight and
fully secure.
9.
Landing Feet
Examine the feet to ensure that they are in good condition and that they are properly
secured to the capsule. Do not go underneath an active lift.
Notes:
i.
Measure height of foot and replace if under 100 mm in height
ii.
Small (20 mm in length) cuts are acceptable but feet should be
replaced when damage larger than 20mm is present.
