8.9. Tightening Torques

The brake pressure regulator can only be adjusted with the help of two pressure gauges. Practically every model in the covered range has a different pressure setting, depending on the fitted engine, the wheelbase, the carrying capacity and the type of body. Only your workshop will be able to check and/or adjust the regulator. An adjusting linkage on the mounting of the regulator is used for the adjustment.

9.0.0 Battery Care

The 12 volts battery consists of six cells, made-up of positive and negative plates, surrounded by a sulfuric acid solution. The battery provides the current to start the engine, for the glow plug system, the lighting of the vehicle and other current consumers.

The following maintenance operations should be carried out at regular intervals to extend the life of the battery and to always keep it at its peak performance.

• Check the battery level once a week. If the battery case is translucent, the level can be seen through the case. Otherwise the filler plugs will have to be removed for inspection. If the electrolyte is below the separator plates, add distilled water. Do not over-fill the battery and wipe away any spilled water before replacing the filler plugs. Tap water must not be used to top-up the battery.
• Delco batteries incorporate a battery checker, which enables an easy check of
