STEP 5
Allow the oil to drain completely� It is important to ensure
the vehicle is on a flat level surface when draining the
oil to ensure its complete removal� The oil pan should
catch approximately 1 quart of used oil; LP gas powered
generators may not darken the oil as much as a gasoline
or diesel powered engine� This is due to lower density of
carbon and deposits produced in the burning process and
fewer impurities typically contained within LP gas versus
gasoline or diesel fuel� Therefore, the oil will usually
appear cleaner than expected during its removal� Do not
assume the old oil is good, because it looks clean� The
oil’s viscosity still breaks down under extreme operating
temperatures and must be changed regularly�
STEP 6
Carefully re-install the oil drain plug and tighten it securely
to avoid a leak� Do not over tighten the plug as this may
strip the threads on the plug or the crankcase� Wipe the
area around the plug with a clean dry rag to remove any
oil residue; and,
STEP 7
Following the Recommended Engine Oil and
Specifications (Capacity) Section of the ONAN QG 2500
Generator Manual, replace up to 1 quart of oil in the
generator through the oil dipstick indicator fill.
To do this, remove the oil level dipstick indicator and replenish the oil
through the oil fill port using a hand pump or long neck funnel. Add the
oil slowly and be sure not to over fill the level.
WARNING
Wear proper personal protective equipment (rubber gloves
and face shield) when changing the generator’s oil. Hot oil can
cause severe burns if spilled or splashed on exposed skin.
warning
NOTE
Only use oil that meets American Petroleum Institute (API)
designation SG. Oil should be labeled as having passed
MS Sequence Tests (also known as ASTMG-1V Sequence
Tests). Oil grade 15W-40 is recommended. Refer to the
Onan QG 2500 Generator Manual for recommended service
intervals and additional information.
■ Air Filter
Replace the air filter every 150 hours as recommended on the
Periodic Maintenance Schedule, or more often in extremely dusty
environments. Use ONAN approved filters only.
STEP 1 Remove the generator service hatch cover;
STEP 2
Depress the two tabs and push them to the right
simultaneously to unseat the air filter cover. Then pull
the cover towards you;
STEP 3
Gently remove the air filter by pressing the blue / green
rubber seal to the right, which will unseat it from the
filter housing. Pull it towards you to remove the
old filter;
STEP 4
Inspect the carburetor to make sure it is clean� If it is
coated with oil and dirt, use a carburetor cleaner spray
to remove any oil and dirt residue;
STEP 5
Install a new ONAN approved filter by gently sliding it
fully into the housing and to the left; and,
STEP 6
Install filter cover by gently pushing the cover inwards
to engage the inner mounting tabs and then pushing
the cover to the left to latch the two locking tabs that
you first pressed to remove the cover.
■ Battery Care
Your generator starts using the house battery bank� To ensure
your house batteries are performing efficiently, perform these
preventive maintenance actions and inspections:
STEP 1 Remove the generator service hatch cover;
STEP 2
Depress the two tabs and push them to the right
simultaneously to unseat the air filter cover. Then pull
the cover towards you;
