The PowerView gauge includes a liquid crystal display (LCD) screen. The display is programmed to show six NFPA required engine parameters simultaneously. The diagnostic gauge uses two arrow keys (A) and (B) for scrolling through the engine parameter list and viewing the menu list. An enter key (E) is used for selecting highlighted items.

3.2 AIR/EXHAUST SYSTEM 3.2.1 Ambient Conditions Clarke engines are tested in accordance with SAE J1349 (Clarke USA) or ISO 3046 (Clarke UK). In this capacity, they may be de-rated to meet certain site conditions, failure to do so can seriously impede the performance of the engine and could lead to premature failure.
A slight pressure is maintained within the engine crankcase compartment. Vapors are expelled through a vent pipe attached to the rocker cover. Ref. Figure #15. Contact Clarke for an optional breather kit if vapors accumulate in your pump room.
The installation of the exhaust system should consist of the following: Personnel protection from hot surfaces. Adequate supports to prevent strain on the engine exhaust outlet and minimize vibration. Protection against entry of water and other foreign matter. While the engine is running inspect exhaust pipe outlet outside of the pump room itself for environmental hazards such as excessive smoke conditions.
3.3.4 Oil Specification Diesel Engine Oil This engine is filled at Clarke with SAE 15W-40 oil meeting CAT ECF-3 specification. Important: Do not add makeup oil until the oil level is BELOW the add mark on dipstick. Add Cat DEO 15W-40 or equivalent when makeup oil is required.
MODEL CAPACITY combination of these. Chlorides and/or sulfates tend to QUARTS (LITERS) accelerate corrosion, while hardness (percentage of C18H-All Models 40 (37.9) magnesium and calcium salts broadly classified as carbonates) causes deposits of scale. Water within the 3.4.5 Coolant Inhibitors limits specified in figure #17 is satisfactory as an engine coolant when properly inhibited.
