* During initial operation of a new engine, change oil and filter at 50 hours, first time only. Service interval depends on type of oil.

* 2 Add supplemental coolant additives (SCAs) to recharge the engine coolant.
* Replace the primary air filter element when the restriction indicator shows a vacuum of 625 mm (25 in. H

A
* ccumulation of carbon (soot, unburned fuel) in the exhaust pipeline and muffler could cause not only system derates but also could lead to a
4
fire incident. To destroy the soot and unburned fuel, run the unit at rated power for some period of time until the exhaust gas becomes mostly
colorless every 250 hours of operation time. The carbon will be generated more easily when the unit operates at less then 40% of rated power. In
this case, perform the above procedures at a shorter interval time.
A
* pplying a large load at one time to the unit when carbon deposits have accumulated in the exhaust system could produce fire/sparks which
5
could lead to abnormal combustion. Therefore it is recommended to appy the load gradually and observe the exhaust gas color (colorless)
during the process.
* Fire or sparks may emit from the exhaust gas outlet during the carbon emission accumulation check (load). Make sure the area surrounding
6
the unit is free from any flammable material.
