Just been reading my 90s origional manual with regerds to the topic in question;
DESCENDING STEEP SLOPES
Stop the vehicle at least a vehicles length before the slope and engage first gear, low range with differential locked. Check gear engagement before moving off. Do not touch the brake or clutch before the descent-the engine will limit the speed, and the vehicle will remain perfectley under control while the front wheels are turning. If the vehicle begins to slide, accelerate to maintain directional stability.
DRIVING IN SOFT, DRY SAND
When conditions are soft, reduced tyre pressures will increase the contact area, and help improve traction and reduce the tendency to sink. Select a gear, lock the differential and stay in it.
Because of the drag of the sand, the instant the clutch is disengaged the vehicle will stop. If a standing start in sand or on the side of dunes is necessary, exercise care in applying the accelerator pedal, as sudden power will induce wheel spin and cause the vehicle to dig itself into trouble.
ICE AND SNOW
Land Rovers are, of course, used extensively in snow and icy conditions. The driving techniques are generally the same as driving on mud or wet grass. Select the highest gear possible with differential locked and use only suffcient engine revoloutions to just move the vehicle forward without labouring. Avoid violent movements of the steering wheel and use the brakes, with care, only if necessary.
NOTE: The differential lock can be engaged or disengaged at any speed providing the road wheels are not spinning at different revoloutions. For example, in slippery conditions if one wheel is spinning, ease off the accelerator before engagement.
VEHICLE RECOVERY
Should the vehicle become immobile due to loss of wheel grip, the following hints could be of value:
(a) Avoide prolonged wheel spin; this will only make matters worse.
(b) Try to move obsticles rather than force tte vehicle to cross them.
(c) If the groung is very soft, reduct tyre pressures if this has not previousley been done.
(d) Clear clogged tyre treads.
(e) Reverse as far as possible, then the momentum reached in going forward again may get the vehicle over the obsticle.
(f) Brushwood, sacking, or any similar 'mat' material placed in front of the tyres will thep in producing tyre grip.
(g) If possible, jack up the vehicle and place material under the wheels. Great care must be taken when doing this to avoide personal injuary.
USE OF THE TRANSFER GEAR LEVER CAUTION:
Changing from locked H to L, should only be attempted when the vehicle is stationary. Depress the clutch pedal and push the lever fully forward, release the clutch. Should there be any hesitation in gear engaing, do not force the lever. With the engine running, engage a gear with the main gear lever and release the clutch momentarily, then return the main gear lever to neutral and try the transfer control again.
Changing from L to H can easily be made as follows without stopping the vehicle. Depress the clutch pedal and release the accelerator pedal as for a normal gear change. Move the transfer lever into neutral. Release the clutch pedal for three seconds. Depress the clutch pedal and move the transfer lever firmally to the H position. Then move the main gear lever to secong gear and release the clutch pedal while depressing the accelerator to take up normal drive smoothley.
Yes I am bored.
