Check the engine oil at the start of each day, before starting
the engine. If the oil level is low, remove oil filler cap, and
add oil as required.

every 100 hours thereafter. See Engine Manual.
Use only engine oils with API classification CD/CE.

4.4 AIR FILTER_______________________________________________________________
Check the service indicator daily. If red band appears in the
window
(C)
replace the element.
Do not remove the element for inspection or cleaning.
Unnecessary removal of the filter increases the risk of
injecting dust and other impurities into the engine.
When service is required, first clean the outside of the filter
housing; then remove the old element as gently as possible
and discard.
1. Carefully clean the inside of the filter housing without
allowing dust into the air intake.
2. Inspect the new element. Do not use a damaged
element and never use an incorrect element.
3. Assemble the new element and make sure it seats
properly. Reset the indicator by depressing button

.
4. Reassemble cap making sure it seals completely
around the filter housing. Dust evacuator (
E
) must be
facing down.
5. Check all hoses and air ducts. Tighten hose clamps.
