WARNING :

The engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive
harm.

NOTICE

FEDERAL EMISSION COMPONENT DEFECT WARRANTY and CALIFORNIA
EMISSION CONTROL WARRANTY are applicable to only those engines/
generators complied with EPA (Environmental Protection Agency) and CARB
(California Air Resources Board) emission regulations in the U.S.A.

NOTICE

To the engines/generators exported to and used in the countries other than the
U.S.A., warranty service shall be performed by the distributor in each country in
accordance with the standard engine/generator warranty policy as applicable.

AIR INDEX

To show compliance with California emission regulations, a hangtag has been
provided displaying the Air Index level and durability period of this engine.

ENGLISHFRANÇAISEESPAÑOL

The Air Index level defines how clean an engine’s exhaust is over a period of
time. A bar graph scaled from “0” (most clean) to “10” (least clean) is used to
show an engine’s Air Index level. A lower Air Index level represents cleaner
exhaust from an engine.

The period of time (in hours) that the Air Index level is measured is known as
the durability period. Depending on the size of the engine, a selection of time
periods can be used to measure the Air Index level (see below).

Descriptive Term Applicable to Emissions Durability Period

Moderate - 50 hours (engine from 0 to 80 cc)

125 hours (engine greater than 80 cc)

Intermediate - 125 hours (engine from 0 to 80 cc)

250 hours (engine greater than 80 cc)

Extended - 300 hours (engine from 0 to 80 cc)

500 hours (engine greater than 80 cc)

Notice : This hangtag must remain on this engine or piece of equipment, and
only be removed by the ultimate purchaser before operation.

MAKITA , a distributor of small off-road equipment in the U.S., warrants to the owner of 2005

and later engines that the engine (1) has been designed, built, and equipped at the time of man­ufacture so as to conform with the applicable regulations of the California Air Resources Board
and, (2) is free from defects in materials and workmanship which may cause it to fail to conform
with those regulations as applicable according to the terms and conditions stated below.

WARRANTY PERIOD

Repair and/or replacement of any warranted emission-related part will be performed at no
charge provided the work is performed at an authorized warranty station. There will also be no
charge for any diagnostic labor performed at an authorized warranty station which leads to the

Any warranted part which is not scheduled for replacement as required maintenance, or which is
scheduled only for regular inspection to the effect of "repair or replace as necessary" shall be
warranted for the warranty period. Any warranted part which is scheduled for replacement as
required maintenance shall be warranted for the period of time up to the first scheduled replace­ment of that part. This warranty shall apply only towards the repair, replacement, and/or adjust­ment of the component parts listed below.

distributors, or warranty stations shall not be liable for any loss of use of the engine, for any

CONNECT SUCTION HOSE

Use a reinforced-wall or wire braided hose

to prevent suction collapse.

Since the pump's self-priming time is

directly proportional to hose length, a

short hose is recommended.

CAUTION

Always use a strainer with the
suction hose. Gravel or debris
sucked into the pump will cause
serious damage to the impeller and
the pump casting.

CONNECT DELIVERY HOSE

When using a fabric hose, always use a
hose band to prevent the hose from
disconnecting under high pressure.

level is low, refill to the upper level
with the following recommended oil.

■

Use 4-stroke automotive detergent oil
of API service class SE or higher grade
(SG, SH or SJ is recommended).

CHECK PRIMING WATER

It is recommended that the water
chamber of pump casing should be
primed with full of water before
operating.

WARNING

Never attempt to operate the
pump without priming water or
the pump will overheat.
Extended dry operation will
destroy the mechanical seal.
If the unit has been operated
dry, stop the engine immediately
and allow the pump to cool
before adding priming water.

5. MAINTENANCE SCHEDULE

MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES
AND SYSTEMS MAY BE PERFORMED BY ANY NONROAD ENGINE REPAIR ESTAB­LISHMENT OR INDIVIDUAL.

DAILY INSPECTION

Before running the engine pump, check the following service items:

Check priming water

Clean air cleaner element Enough gasoline

Enough gasoline

Loose or broken bolts and nuts Enough clean engine oil

Leakage of gasoline and engine oil

Excessive vibration,noise

Safe surroundings

PERIODIC MAINTENANCE

Periodic maintenance is vital to safe and efficient operation of your engine pump.
Check the table below for periodic maintenance intervals.

IT IS ALSO NECESSARY FOR THE USER OF THIS ENGINE PUMP TO
CONDUCT THE MAINTENANCE AND ADJUSTMENTS ON THE EMISSION­RELATED PARTS LISTED BELOW TO KEEP THE EMISSION CONTROL SYS­TEM EFFECTIVE.

The emission control system consists of the following parts:

(1) Carburetor and internal

parts

(2) Cold start enrichment

system, if applicable

(3) Intake manifold, if

applicable

(4) Air cleaner elements

(5) Spark plug

(6) Magneto or electronic

ignition system

(7) Spark advance/retard

system, if applicable

(8) Exhaust manifold, if

applicable

(9) Hoses, belts, connec-

tors, and assemblies

The maintenance schedule indicated in the following table is based on the normal
engine operation. Should the engine be operated in extremely dusty condition or in
heavier loading condition, the maintenance intervals must be shortened depending
on the contamination of oil, clogging of filter elements, wear of parts, and so on.

*NOTE: 1. Initial oil change should be performed after first twenty (20) hours of

operation. Thereafter change oil every hundred (100) hours.
Before changing oil, check for a suitable way to dispose of old oil.
Do not pour it down into sewage drains, onto garden soil or into open
streams. Your local zoning or environmental regulations will give you
more detailed instructions on proper disposal.

place the oil gauge in a place where
it will not gather dirt, dust or other
foreign matter.

2) Place a cloth or paper towel to the
area around the oil filler hole.

3) Remove the oil gauge, then tilt the
engine and drain the oil into a pan or
other receptacle.

4) Put the engine on a level surface,
then fill with the oil up to the point of
overflowing the filler neck. Pour the
oil in from a squeeze bottle or other
appropriate.

9. SPARK ARRESTER (OPTIONAL)

SPARK ARRESTER

In a dry or wooded area, it is recommendable to use the prodoct.with a spark arrester.

Some areas require the use of a spark arrester. Please check your local laws and
regulations before operating your

prodoct

The spark arrester must be cleaned regularly to keep it functioning as designed.
A clogged spark arrester :

● Prevents the flow of exhaust gas

● Reduces engine output

● Increases fuel consumption

● Makes starting difficult

If the engine has been running, the muffler and the spark arrester will be very hot.
Allow the muffler to cool before cleaning the spark arrester.
