Always use caution when using power tools.
Always wear protective eye goggles
when working with compressed air.
4
When using compressed air to clean a component such as an air silencer, use a safe
amount of air. Recommendations regarding the use of air are indicated throughout the
manual. Too much air can rupture or in some other way damage a component and
create a hazardous situation that can lead to personal injury.
5
Avoid the use of carbon tetrachloride as a cleaning agent because of the harmful
vapors that it releases. Use perchlorethylene or trichlorethylene. However, while less
toxic than other chlorinated solvents, use these cleaning agents with caution. Be sure
the work area is adequately ventilated and use protective gloves, goggles or face
shield and apron. Exercise caution against burns when using oxalic acid to clean the
cooling passages of the engine.
6
Avoid excessive injection of ether into the engine during start attempts. Follow the
instructions on the container of the starting aid.

When working on an engine that is running, accidental contact with the hot e haust
x
manifold can cause severe burns. Remain alert to the location of the rotating pulleys
and belts.
(10) Engine Specifications - (Less Major Assemblies).
Specifications, clearances and wear limits are listed below. It should be specifically noted that the
clearances apply only when all new parts are used at the point where the various specifications apply. This also
applies to references within the text of the manual. The column entitled "Limits" in this chart lists the amount of
wear or increase in clearance which can be tolerated in used engine parts and still ensure satisfactory
performance. It should be emphasized that the figures given as "Limits" must be qualified by the judgement of
the personnel responsible for installing new parts. These wear limits are, in general, listed only for the parts
more frequently replaced in engine overhaul work. For additional information, refer to the text.
