Maintenance

Owner’s Manual for Portable Generator

17

DO NOT use a garden hose to clean 
generator. Water can enter engine fuel 

system and cause problems. If water enters generator 
through cooling air slots, some water will be retained in 
voids and crevices of rotor and stator winding insulation. 
Water and dirt buildup on generator internal windings will 
decrease insulation resistance of windings.

Engine Maintenance

Accidental start-up. Disconnect spark 
plug wires when working on unit. Fail-

ure to do so could result in death or serious injury.

Engine Oil Recommendations

All  oil  should  meet  minimum American  Petroleum  Insti-

tute (API) Service Class SJ, SL or better. Use no special

additives. Select the oil's viscosity grade according to the

expected operating temperature (also see chart).

Above 40° F, use SAE 30

Below 40° F and down to 10° F, use 10W-30

All temperatures, use synthetic 5W-30

Use  petroleum  based  oil  for  engine  break-in  (30  hours)

before using synthetic oil.

Any attempt to crank or start the 
engine before adding the recom-

mended type and quantity of engine oil can result in 
engine damage.
Inspect  engine  oil  level  prior  to  each  use,  or  every  8

hours of operation.

1.

Place generator on a level surface.

2.

Clean area around oil fill.

3.

Remove oil fill cap and wipe dipstick clean.

4.

Screw dipstick into filler neck. Verify oil level is within safe

operating range as shown.

5.

Add recommended engine oil as necessary.

6.

Replace oil fill cap and hand-tighten.

Some units have more than one oil fill 
location. It is only necessary to use one 

oil fill point.

Change Engine Oil

Accidental start-up. Disconnect spark 
plug wires when working on unit. Fail-

ure to do so could result in death or serious injury.
When using generator under extreme, dirty, dusty condi-

tions,  or  in  extremely  hot  weather,  change  oil  more  fre-

quently.

Don’t pollute. Conserve resources. 
Return used oil to collection centers.

Change oil while engine is still warm from running, as fol-

lows:

1.

Place generator on a level surface.

2.

Disconnect  the  spark  plug  wire  from  the  spark  plug  and

place the wire where it cannot contact spark plug.

3.

Clean area around oil fill, and oil drain plug. 

4.

Remove oil fill cap.

5.

Remove oil drain plug and drain oil completely into a suit-

able container.

6.

Install oil drain plug and tighten securely.

7.

Slowly pour oil into oil fill opening until oil level is between L

and H marks on dipstick. DO NOT overfill.

8.

Install oil fill cap, and finger tighten.

9.

Wipe up any spilled oil.

10.

Properly dispose of oil in accordance with all applicable reg-

ulations.

Air Filter

Engine will not run properly and may be damaged if run

with  a  dirty  air  filter.  Service  air  filter  more  frequently  in

dirty or dusty conditions.
To service air filter:

1.

Turn knob (A) and remove air filter cover.

2.

Wash in soapy water. Squeeze filter dry in clean cloth (DO

NOT TWIST).

3.

Clean air filter cover before re-installing it.

To order a new air filter, contact the near-
est authorized service center at 1-888-

431-6871.
