touch-and-go can mean
"risky; precarious" or "hasty, sketchy"
Etymology Online suggests:
Touch and go (adj.) is recorded from 1812, apparently from the name of a tag-like game, first recorded 1650s
Another version from Loose Cannons and Red Herrings, by Robert Claiborne states:
TOUCH AND GO
Meaning: A risky, precarious situation
Origin: “Dates back to the days of stagecoaches, whose drivers were often intensely competitive, seeking to charge past one another, on narrow roads, at grave danger to life and limb. If the vehicle’s wheels became entangled, both would be wrecked; if they were lucky, the wheels would only touch and the coaches could still go.”
A far more authoritative answer from user Ken Greenwald on the wordwizard forum explains more with examples, quoted verbatim:
TOUCH AND GO is used as both a noun and adjective (‘touch-and-go) and means a precarious situation in which the outcome is doubtful or extremely uncertain for a time – a close flirtation with danger or disaster. “It was touch and go after his surgery, but he pulled through.” “He was familiar with the touch and go of guerilla warfare.” It also has a second meaning of ‘quick action or movement,’ “One must learn to deal with the touch and go of city traffic.’
The first appearance of ‘touch and go’ in a literal sense was in the 16th century (see quote below) as a verbal phrase (used as noun or adjective) meaning to touch for an instant and immediately go away or pass on; to deal with momentarily or slightly. In the early 19th century the phrase took on its two other figurative meaning – 1) adjective: [1812] Involving or characterized by rapid, slight, or superficial execution; sketchy; casual, careless; instantaneous; expeditious. 2) noun: [1815] precarious situation.
The familiar sense of ‘precarious situation’ originated in the early 19th century with reference to coach driving or ship pilotage and appears to have been a literal allusion to a vehicle barely escaping collision. Coach drivers used the term ‘touch and go’ for a narrow escape after the wheels of two coaches touched in a near accident – the wheels would TOUCH, there would be a moment of extreme anxiety, but neither vehicle was stopped, and each could GO on. For sailors a ship was said to ‘touch and go’ when its keel scraped the bottom without stopping the boat or loosing a significant amount of speed. A second nautical use referred to the practice of approaching the shore to let off cargo or men, but in an attempt to save time and avoid the involved procedure of stopping – not stopping. It has been speculated by some that the great risk and uncertainty involved in this maneuver spawned the expression.

According to this site on restaurant phrases, all-day means:
that you are counting particular items on the ticket rail, as in "Yes, chef, there are six chicken saltimbocca all-day, three beef tenderloin all-day," and so on. This counting method is a safeguard against forgetting to fire the requisitioned amount of food, especially when the dining room is full and the rail is lined with greasy slips of white paper. Things do get hectic during the dinner rush, and a basic "all-day" count can save your ass when you are plating food.
There is no etymology I could find on where this phrase comes from, but in non-restaurant English all day has been around since c.1000.

The machine is up/down is an instantiation of a Metaphor Theme.
English speakers (like all humans) are oriented vertically with respect to a gravitational field, so the
UP/DOWN
dimension is significant, and English uses it in a variety of metaphor themes.These themes include:
UP
isMORE
(DOWN
isLESS
):The prices are rising/falling.
The stock market’s moving up/crashing.
Turn the volume up/down.
UP
isHAPPY
(DOWN
isSAD
):He’s depressed.
feeling up/down
What a downer!
UP
isPOWERFUL
(DOWN
isWEAK
):upper/lower classes
superior/subordinate
the highest levels
UP
isACTIVE
(DOWN
isPASSIVE
):The computer is up/down.
Are you up for some handball?
Rise to the occasion.
UP
isBETTER
(DOWN
isWORSE
):higher/lower animals
He fell down on the midterm.

UP

):He’s got his head in the clouds.

higher mathematics
high-level cognitive functions
low-level details
new heights of abstraction
down-to-earth solution
All of these themes are coherent; that is, we tend to think of them in the same ways (e.g,
LESS, SAD, WEAK, PASSIVE
, andWORSE
are all negative evaluations, and vice versa.)
