Cam screws:
These get screwed into the provided 5mm holes first.
Cam Housing:
Tighten the pre-installed cam housing with a Philips Head screwdriver, half a turn each. Please note overtightening cam housing may affect the tight fit of the plastic cover caps (these go on last).
Do not use a drill to tighten cam housing.
Top:
Install the top last unless you have a hutch which will be placed on after the top.
