MAINTENANCE/SERVICE
 
Diesel Engine: Air Intake System 
 
AIR CLEANER 
 
IMPORTANT: Do not run engine with air cleaner 
disconnected or disassembled. 
 
The air cleaner is equipped with a vacuator valve 
which removes dust continuously from the air 
cleaner housing. 
 
Check daily that system is functioning properly: 
 
1. Remove air cleaner end cap (A). 
2. Check for dust inside the canister. 
3. If dust or debris is present, clean canister and 
check for the source of the contamination. 
Possibilities are: 
a. Obstruction in vacuator valve (B). Clean or
replace if necessary.
b. Loose connection at any air-intake hose clamp.
Tighten hose clamp.
4. Reinstall air cleaner end cap. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
FILTER ELEMENTS - CLEANING AND INSPECTION 
 
The diesel engine air cleaner is equipped with a 
restriction gauge (A) which signals red when the 
primary filter element requires cleaning. Check 
restriction gauge daily. Never clean filter element 
unless restriction gauge signals red. Excessive 
cleaning will shorten element life. After cleaning, 
re-set restriction gauge by pushing button on top of 
gauge. 
 
IMPORTANT: The air cleaner is a dual element 
type. Clean the primary (outer) element only. Do 
not attempt to clean the secondary (inner) 
element. If there is visible dirt on the secondary 
element, replace both primary and secondary 
elements. See "Filter Elements - Replacement" for 
normal change interval. 
 
To clean air filter element: 
1. Remove element from air cleaner canister. 
 
2. Clean inside of canister and cover with a damp 
cloth.
 
3. Inspect element as follows: 
- Hold a bright light (B) inside element and check 
carefully for holes. Discard any element which 
shows the slightest hole. 
-
Be sure outer screen (C) is not dented.
Vibration would quickly wear a hole in the filter.
- Be sure filter gasket (D) is in good condition. If
gasket is damaged or missing, replace element.
 
4. Pat sides of element gently to loosen dirt. Do 
not tap element against a hard surface.
