ENGINE
Check and Adjust Governor Lever
1. Check that the governor lever (1) makes firm contact
with the high idle stop and the low idle speed limit
screw when the engine speed control is in the full
speed or low idle speed positions.
2. If the governor lever does not make proper contact with
the high idle stop or the low idle speed limit screw,
adjust the throttle cable or linkage as necessary.
Do not change the no-load minimum or maximum
revolution with the limit bolt. Otherwise, the safety
and/or performance of the machine may be
deteriorated or the service life of the machine may
be reduced.
Adjust Intake Valve and Exhaust Valve Clearance
Proper adjustment is necessary to maintain the correct timing for opening and closing the valves.
Improper adjustment will cause the engine to run noisily, resulting in poor engine performance
and engine damage.
Check of Fuel Injection System
Proper operation of the fuel injectors is required to obtain the optimum injection pattern for full
engine performance. The EPA/ARB requires that you have the injectors inspected, cleaned and
tested every 1500 hours.
Inspect Crankcase Breather System
The crankcase breather system must work properly so that the engine meets the exhaust gas
regulations for long. Inquire our service office about the necessary works.
Clean Coolant System
Rust and scale adhere to the coolant system naturally in long-term use, resulting in bad cooling.
As a result, the cooling efficiency is reduced, the engine oil is not cooled sufficiently and oil is
deteriorated earlier.
Lap Intake and Exhaust Valves
Adjustment is necessary to maintain proper contact of the valves and seats.
