Unless you’ve got a big un (ooer missus) like a V8, you’ll always need 1st pulling away with a fully loaded Scanny, this rev limiting thing has been in place for many years, first came across in a Renault G Manager with slapover 4/4, lovely lorry
First is always low enough to get going with the reduced revs, but if you’re on a really steep hill in the damp with a full load, and you have a 3 axle tractor you might find it advantageous to dump the mid lift air before trying to move off, its the button with the umbrella over the two axles image, in most modern Scanny’s soon as you press that the dash will put up a display showing the weight being tranferred onto the drive axle.
Note, these air dump vales usually work below 20kph, above that on most lorries they don’t work, and as you increase speed soon as you hit 20k’s the air dump should self cancel…note not on square Axors where you could drive round all day with the axle up if you wanted to.
If this is a regular lorry and you do a lot of loaded hill work, its worth learning to flick that switch at 20ks as you decelerate fast on a steepening uphill climb, get used to using it before you need it desperately, because just as in pulling away if the vehicle senses any wheelspin from the drive axle at all it will cut engine power just when you need it, and one thing Scanny 6 pots don’t have is an excess of spare power.
Also for really slippery conditions, it can be handy to switch off traction control (TC) when severe hill climbing (or pulling away in slippery conditions or maneuvering), that will prevent the engine cutting power when it senses wheel slip, but take care cos that TC will stay off once you turn it off, an icon will display on the dash to warn you, so remember to turn TC back on soon as you’ve completed the climb in hand.
Oh ■■■■■■■■, ignore most of that and pick out what’s suitable or amend to 3 axle rigid if you have one, just assumed you was in artic
