Timing Problem

[bolo 2]

In-laws have a timer but have no idea how it works. Unlike the pic attached, the timer has 4 pegs, 2 red and 2 blue. The heating comes on early but goes off at 11.30am. Comes on again at 5pm and off again at 10pm.
Q1. Can the pegs, be moved to another time and if so how is it done? At the moment they are too scared to touch it in case they break something.
Q2. Can’t the middle pegs be removed altogether, and if so how?
Q3. If they want to stay up later, how does one override the system?

Cheers mate. Using the manual via your link and giving the instructions via the phone, the timer is now operating perfectly.
