Firstly, use a firm brush to sweep the cover free of debris, including leaves, mud, twigs etc.
Step 2 – Clear edge
Use the bevelled edge of your manhole key to scrape any mud and rust away from around the edge of the manhole cover.
Step 3 – Ask someone to help
Ask a co-worker to lift with you. The job will usually need two people as cast iron manhole covers are very heavy and need to be lifted vertically and laid down safely. However, plastic and lightweight manhole covers can be lifted by a single person.
Step 4 – Insert keys
Insert the keys into the keyway.
Twist the key half way to lock it in place. In the locked position, the key will not come free from the slot. It doesn’t matter whether the key is turned clockwise or anti-clockwise, either direction will allow you to reach a locked position. You can now lift the manhole cover.
Step 5 – Communicate
Make sure your co-worker is doing the same thing at the same time as you. Double check that both keys are locked firmly in place.
Step 6 – Place cover
Plan with your co-worker where you will put the cover. Ensure that neither of you will have to step over the hole to place the cover on the ground. You will both have to walk sideways to avoid one of you falling in.
Step 7 – Lift cover
Make sure both you and your co-worker are bending your knees. Agree to lift at exactly the same time and then lay the cover on the ground in the agreed place.
If the cover is stuck…
Strike the cover firmly around the edge with a piece of timber. The vibration should loosen it.
Some covers are screwed into place with bolts, if they become stuck, try soaking them in oil before trying to undo them.
Spray around the edge of the manhole cover with WD40 and leave it for a while; this can help to loosen it.
If there are prise holes around the edge of the manhole cover, insert a crowbar into the holes to loosen the cover before lifting.
