Altitude
NA engines Continuous duty Deduct 3% for each 1000 (305m) above 1500 (457m.) Intermittent duty Deduct 3% for each 1000 (305m) above 500 (152m.)
Temperature
Continuous duty Deduct 1% for every 10F. (6C.) above 100F (38C.) Intermittent duty Deduct 1% per 10F. (5.5C.) above 85F. (29C.)
Intermittent Rating (I)
The highest load and speed that can be applied under specific conditions of varying load and/or speed.
Continuous Rating (C)
The load and speed that can be applied without interrup-tion except for normal maintenance.
All ratings corrected to 500 (152m) altitude, 29.38 (746 mm) Hg. and temperature of 85F. (29C.).
Natural gas ratings are based on use of 900 BTU (33.5 J/cm) LHV gas. Propane ratings are based on use of
2335 BTU of HD-5 propane.

Currently in stock and available for all multi cylinder engine applications. Extra room inside for panels or any other required equipment.
Ideal for PC pump applications and generators. Built in tank can be used for hydraulic fluid, engine make-up oil or any other type of required fluids. Also available without the tank.
Clutch ActuatorArrow has introduced its new patented Clutch Actuator
(CO-00) for C-Series and A-Series Engines. This new actuator features a simple 2 wire and 12V connection for ease of installation. All adjustments are made out-
side the unit on the linkage that connects the actuator to the clutch lever. This in conjunction with the New
Style AutoStart (Autostart-NS) is the simplest and easi-est to use and install electronic automation package
available anywhere.
AutoStart NSOur new Autostart-NS for C Series and K Series engines is a simple, programmable system that allows for different cycles each day of the week as well as continuous monitoring of criti-cal engine operating parameters and automatic shutdown. This system features a simple to install 8 wire system, as well as a built in tachometer, hour meter and battery voltage meter. The automation can be set to real time, interval timing or manual mode, giving you everything you need to easliy automate and monitor your oil field operations.
