SAFETY
CAUTION
• When the engine is operated in dusty
conditions, clean the air cleaner
element more frequently.
• NEVER operate the engine with the air
cleaner element(s) removed. This may
allow foreign material to enter the
engine and damage it.
CAUTION
The maximum air intake restriction, in
terms of differential pressure
measurement, must not exceed 0.90 psi
(6.23 kPa; 635 mmAq). Clean or replace
the air cleaner element if the air intake
restriction exceeds the above
mentioned value.
CAUTION
It is important to perform daily checks.
Periodic maintenance prevents
unexpected downtime, reduces the
number of accidents due to poor
machine performance and helps extend
the life of the engine.
CAUTION
If the oil pump must be replaced, replace
it as an assembly only. Do not replace
individual components.
