3.5 Operating Conditions Engine Operation

3.5.1 Winter Operation

● Lube Oil Viscosity

- Select oil viscosity (SAE grade) according to

ambient temperature before starting engine,

see 4.1.2.

- Increase oil change frequency when operating

below -10°C, see 6.1.1.

● Diesel Fuel

- Use winter-grade diesel fuel for operation be

low 0°C, see 4.2.2.

● Additional Maintenance Work

- Drain sludge from fuel tank once a week (undo

sludge drain screw).

- If necessary, allow oil in oil bath air cleaner and

engine oil to settle at ambient temperature.

- Below -20°C, after removing starter if neces

sary, smear ring gear on flywheel via pinion

bore from time to time with cold-resistant

grease.

(e.g. Bosch grease FT 1 V 31).

● Cold Start Assistance

- At temperatures near or below freezing point,

use glow plugs if necessary, see 3.2.1.

This not only lowers starting limit temperature,

but provides easier starting at temperatures

normally not requiring a starting aid.

● Battery

- Efficient cold starting requires that battery is

well-charged, see 6.7.1.

- Starting limit temperatures can be lowered by

4-5°C by heating battery up to about +20°C. (To

do so, remove battery and store in warm place).
