Charlie, the 1405 is a fairly modern solid state oscilloscope. I would not consider any recapping unless there is an obvious problem. Most likely the only service it will need is a cleaning of the pots and switches.

Here is a link to the service manual:

You can use a simple shielded cable with alligator clips as test  leads.

The user manual gives some basic info on how to use it:
