For all shacman gear box changes, press the clutch twice. For example, first step down clutch, then shift gear from 1st to Neutral, loose clutch; second step down clutch again, then shift gear from Neutral to 2nd gear.
When shacman spare parts changing from a low gear to a high gear, e.g. from 5th to 6th, first move the valve lever from "L" to "H", then depress the clutch, move the gear to neutral, release the clutch, then depress the clutch again, move the gear to 6th.
Do not use gear shifting for low and high range shifts such as 4th to 6th or 7th to 5th as this will damage the deputy box synchroniser. (Shacman spare parts)
The deputy box will only shift to the shacman parts selected range when the gear is in neutral.
