11.INSTALLATION
Engine life, ease of maintenance and inspection, frequency of checks and repairs, and operating cost all
dependontheway in whichtheengine is installedReviewthefollowinginstructionscarefullyfor. installing the engine.
When mounting the engine, carefully examine its position, the method of connecting it to a machine, the foundation, and the mehtodof supporting the engine. Whendeterminingitsmountingposition,inparticular,makesurethatgasolineandoilcaneasilybe supplied and checked, the spark plug can easily be checked, the air cleaner can easily be serviced, and
that the oil can easily be discharged.
Fresh air is necessary for cooling the engine and burning the fuel.
In the case the engine is operated under a hood or in a small room, temperature rise in the engine room can cause vapor lock, oil deterioration, increased oil consumption, loss of power, piston seizure, shorter engine life, etc., making it impossible to operate the engine properly.It is necessary, therefore, to provide a duct or baffle to guide cooling air to the engine to prevent recirculation of he hot air used for engine cooling, and temperature riseof the machine.
Keep the engineroom temperature below 50°C even in the hottest periodof the year.

outdoors. If a long exhaust pipe is used in such a case, the internal resistance increases causing loss of engine power. Thus pipe inside diameter must be increasedin proportion to exhaust pipe length.
Exhaust pipe: Less than 3m long, pipe inside diameter 30mm, Less than 5m long, pipe inside diameter 33mm.
Take the following notes into consideration.
*
*The driving shaftof the engine must be parallel to the driven shaftof the machine.
*The driving pulleyof the engine must be in line with the driven pulleyofthe machine.
*Install the engine pulley as close to the engine as possible.
*If possible, span the belt horizontally.
*Disengage the load when starting the engine.
If no clutch is used, usea belt tension pulley or the like.
When using a flexible coupling, runout and misalignment between the driven shaft and engine shaft must be minimized. Runout and misalignment tolerance are specified by the coupling manufacturer.
