MAINTENANCE

To ensure your Pantograph continues to work

correctly and safely, you must make the

following regular checks:

Every 6 months:

Check that the steel wire and counterweight

springs (if installed) are in good condition – that

they are not kinked or twisted and that they

show no sign of cuts/breaks or other

irregularities. Check that all screws on

counterweight springs are tight.

Check that all the fixing screws on top and

bottom attachments are tight and that the

pantograph is firmly fixed to the supporting

structure.

If required, lubricate connecting points of the

double scissor as indicated in figure 7, use a dry

lubricant such as PFTE(Teflon). Never lubricate

the friction drum or cable

All the operations above described and

al operations necessary for the use of

the pantograph must be carried out by

trained staff.
