DCA-150SSJU — MAINTENANCE

Cleaning the Fuel Strainer

Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in diesel. Securely
fasten the fuel strainer cap so that fuel will not leak. Check
the fuel strainer every 200 hours of operation or once a month.

Check Oil Level/Change Oil

Check the crankcase oil level prior to each use, or when the
fuel tank is filled. Insufficient oil may cause severe damage
to the engine. Make sure the generator is level. The oil level
must be between the two notches on the dipstick as shown
in page 27, Figure 9.

To change the oil, remove oil plug located on the bottom of
the generator. Make sure the to use an oil recycle container
to catch the oil. Replace oil plug. Remove the oil filter
located on the left side of the generator. Remove oil filter
gasket and clean filter mounting pad. Lubricate gasket with
small amount of oil and install new oil filter. Tighten filter
with 1/4 turn after gasket contacts filter housing. DO NOT
overtighten.

Fill with correct oil through oil filler located on the left side of
the generator (see page Table for proper oil and specification
table for proper amount). Crank engine (without starting) for
30 seconds to ensure proper lubrication. Start engine and
check for leaks. Stop engine and check oil level.

Replacing Fuel Filter

Close shut-off valve. Throroughly clean fuel filter assembly
and surrounding area. Loosen drain plug and drain fuel into
a suitable container. Firmly grasp the retaining ring and rotate
it counterclockwise 1/4 turn. Remove ring with filter element.
Inspect filter mounting base for cleanliness. Install new filter
element onto mounting base. Be sure element is properly
indexed and firmly seated on base. It may be necessary to
rotate filter for correct alignment.

Cleaning and Installing Ether Canister

Remove safety cap from ether canister. Remove spray
nozzle from canister. Remove the old canister assembly
from the solenoid and properly dispose the old canister.
Install the new canister and canister assembly to the
solenoid.

General Inspection

Prior to each use, the generating set should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for fuel
or oil leaks.

Engine Side, Fuel, Oil and Coolant

(Refer to the Engine

Instruction Manual)

Air Cleaner

Every 50 hours: Remove air cleaner element and clean heavy
duty paper element with kerosene, or foam element with
liquid detergent and hot water. Wrap foam element in a cloth
and squeeze dry. For heavy duty paper element, wipe
excess kerosene with towel. Replace if any damage or unable
to clean.

Fuel Addition

Add diesel fuel (the grade may vary according to season
and locations). Always pour through the mesh filter.

Removing Water from the Tank

After prolonged use, water and other impurities accumulate
in the bottom of the tank. Occasionally remove the drain
cock and drain the contents. During cold weather, the greater
the empty volume inside the tank, the easier it is for water
to condense. This can be reduced by always keeping the
tank as full as possible.

Air Removal

If air enters the fuel injection system of a diesel engine,
starting becomes impossible. After running out of fuel, or
after disassembling the fuel system, bleed the system
according to the following procedure.

To restart after running out of fuel, turn the key switch to the
“START” position for 15-30 seconds. Try again, if needed.
This unit is equipped with an automatic air bleeding system.

Service Daily

If engine is operating in very dusty and dry grass conditions,
a clogged air cleaner will result in high fuel consumption,
loss of power and excessive carbon buildup in the
combustion chamber.

Ether is highly flammable. Do not use near
open fires, flames, or sparks. Do not leave
the canister assembly valve open.
