TO” MAINTENANCE
Maintenance is essential to give a safe and dependable service. The following sections provide
information on how to care for your generator properly and safely. This includes basic inspections and
simple maintenance procedures. Other service tasks that are more difficult, or require special tools
should be carried out by an authorised Crommelins service agent.

read and
follow the maintenance recommendations and schedules in this manual, and

you have the appropriate tools and skills required.
•
FAILURE
to properly maintain this generator, or improper maintenance, or failing to correct a
problem before operation, could result in a significant malfunction in which you can be seriously
injured or killed.
•
MAKE SURE
the engine is stopped and cooled before starting any maintenance, servicing, or
repair.

It is recommended to use ear protection when performing operation, maintenance, and repair
of the generator set.
11.1
ENGINE OIL CHANGE (refer to engine instruction manual for full details)
NOTE:
Before changing oil, make sure there is a suitable way to dispose of the old oil. Do not pour it
down sewage drains, onto garden soil or into open streams. Your local zoning or environmental
regulations will give you more detailed instructions on proper disposal.
For a new engine, the initial oil change should be performed after 20 hours. Thereafter, change oil as per
the engine’s instructions manual.
To change the oil, follow these steps:
STEP 1
Drain oil by removing the drain plug and the oil filler cap while the engine is warm.
STEP 2
Reinstall the drain plug and fill the engine with oil until it reaches the upper level on the oil filler
cap.
STEP 3
Use fresh and high-quality lubricating oil to the specified level as
outlined by the section “PRE
-
OPERATION CHECKS”
. If contaminated or deteriorated oil is used or the quantity of the engine oil
is not sufficient, engine damage will result, and its life will be greatly shortened.
STEP 4
Dispose of oil in accordance with your local zoning or environmental regulations.
11.2
SERVICING THE AIR CLEANER
Maintaining an air cleaner in proper condition is very important.
Dirt induced through improperly
installed, improperly serviced or inadequate elements causes damage and wears out the engine. Always
keep the element clean by following these steps:
STEP 1
Remove the bolt off the air cleaner cover.
STEP 2
Remove the air cleaner cover and cleaner element.
STEP 3
Urethane foam: wash urethane foam element in washing oil (kerosene) or diesel fuel. Then
saturate the element in a mixture of 3 parts kerosene or diesel fuel and 1-part engine oil.
STEP 4
Squeeze the element to remove the mixture and install it in the air cleaner.
NOTE:
Instead of washing oil (kerosene), it is possible to wash the urethane foam element in a
solution of mild detergent and warm water. Then rinse the element thoroughly in clean water. Allow
the element to dry properly. Soak the element in clean engine oil and squeeze out excess oil.
