But Slade issued a cautionary warning as goals from Scott Cuthbert, Jamie Ness, Kevin Lisbie and Shaq Coulthirst kept the O's in secfond place in the table.
"These are great times for us at the moment, things are going well, but we've got to make sure that we stay on track, stay grounded in everything we do and tackle every game with the same attitude," Slade said.
"We want to be strong at home and it was important to us to get the win.
"Our attitude and energy we showed were fantastic and we created so many chances.
"We had to show patience before we went ahead, but there were a host of chances that went begging before we capitalised and got ourselves four goals.
"We set out to win the game, we would have been happy to win it 1-0, but the fact that we got four goals without conceding is fantastic.
"That was very important to me that although we were creating chances, we kept the back door locked.
"What also pleased me is that we haven't been scoring too many goals from set-plays, but we've now scored four in the last three or four games so I've got to be happy with that.
"All three of our substitutes made an impact and that's important."
Carlisle goalkeeper Greg Fleming had pulled off three excellent saves on his league debut to frustrate Orient before he was beaten just before half-time whenCuthbert thundered home a header from a Lloyd James corner.
Two minutes after the break Jamie Ness, on-loan from Stoke, scored with a left-footed volley after another James set-piece.
Goals from Kevin Lisbie after 66 minutes and Tottenham loanee Shaq Coulthirst in added time completed the rout, leaving the visitors boss Graham Kavanagh with much to think about in the week ahead.
