4.1 General Installation Notes
4.1.1 Before installing new parts, remove any rust preventative, protection grease etc.
4.1.2 Check before immediate installation for possible transit damage.
4.1.3 Components which have been stored for a long time (over 1 year) should be re-lubricated in
working conditions before they are put into operation.
4.1.4 Before putting the C-Series screw jack(s) into service, the User must ensure that the plant in
which it is installed complies with all applicable directives, especially those regarding health
and safety at work.
4.1.5 Handle the screw jack with care. The C-Series screw jacks should be handled with care to avoid
damaging the machined drive shafts and the threads of the lead screw.
4.1.6 Before putting the units into service, check the lubricant level. If necessary top up the lubricant
to the required level.
4.1.7 Do not mix greases of different nature or specifications.
4.1.8 If the same type of grease already in use is not available, remove all of the existing lubricant
completely and flush its interior thoroughly with a light solvent before refilling with a new
lubricant.
4.1.9 The structure on which the C-Series screw jack(s) are mounted have ample strength to carry
the maximum load, and should be rigid enough to prevent undue deflection or distortion of the
screw jack supporting members.
4.1.10 It is essential that the C-Series screw jack(s) be carefully aligned during installation so that
the lead screw is running true and the connecting shafts are exactly in line with the input drive
shafts.
4.1.11 When installing several screw jacks to move a common load/item/structure, the jacks should
first be connected to the structure (refer 4.4). The load should be equally distributed between
the screw jacks. The screw jack input drive shafts should then be connected taking care not to
turn the input shaft and lose the screw jack position relative to the structure.
4.1.12 After the C-Series screw jack(s) is installed, shafting, gearboxes, motors, etc., are coupled
together it should be possible to turn the main drive by hand (no load on screw jacks). If there
are no signs of binding or misalignment, the screw jack system is then ready for normal
operation.
4.1.13 After the C-Series screw jack(s) are installed, they should be operated through their full travel
four or five times under minimum load conditions. If the arrangement operates satisfactorily
and there are no signs of binding or misalignment the C-Series screw jack(s) are ready for
normal operation. Refer to section 5 for typical operating performance checks.
