Recoil starter rope can injure you if released suddenly.

When starting the engine, grasp the recoil starter ﬁrmly by the grip. Do not grasp the starter rope itself. Always control

the rope during rewind into the

the

housing. Releasing the starter rope suddenly may allow the rope to whip around and

injure you or damage the recoil starter mechanism.

Proper maintenance is essential for safety.

A well-maintained hand held blower is safer and

operates more

efﬁciently. Regularly

check hand held

is recommended (50 parts gasoline to 1 part oil). Mix it

thoroughly before pouring it into the hand

tank.

CAUTION

Alcohol or "gasohol" may damage the engine.

The hand held blower is designed to run on a

50-to-1

mixture of regular unleaded gasoline (87 octane)

and quality TC class 2–stroke oil or JASO FC

class for air-cooled engines.

The octane rating of gasoline is a measure of its

Pour the measured amount of 2-stroke oil into an approved

resistance to detonation or "knocking". Use a gasoline

with an octane rating equal to or higher than that sho

gasoline container and add the specified amount of gasoline

to the container.

in the table. The Antiknock Index is an average of

the

Research Octane No. (RON) and the Motor Octane

No.

(MON). The Antiknock Index is posted on service

station

pumps in the U.S.A. If the Antiknock Index is not

posted,

be sure the Research Octane No. is adequate.

After refueling, make sure cap is closed securely.

If gasoline is spilled on engine or tank, wipe it off

immediately.

NOTE

Do not use the gasoline that has been stored longer

than two months.

To ensure proper starting at low ambient temperatures,

use fresh,

Filling the Tank:

winter grade fuel.

Level the engine before fueling.

Open the fuel tank cap and ﬁll the tank with 50:1 gas/

Operating Instructions

Starting the Engine

Checking throttle operation

Move the throttle lever and setting lever through its full

range of motion. It must move smoothly all the way, as

shown, without sticking or binding.

CAUTION

Start (ON) Stop

A. Throttle lever

B. Throttle setting lever

Place the hand held blower on firm ground.

Move the stop switch to the "ON" position.

Starting the engine

Engine speed can not be adjusted if the throttle

lever and setting lever does not move

smoothly all the way and

without binding.

A. Stop switch

16 OPERATING INSTRUCTIONS

Slowly push the priming pump several times until the

fuel comes out of the overflow tube. When the gasoline

flows, stop pushing the priming pump.

NOTE

The fuel that flows by pushing the priming pump is

designed to return to the fuel tank.

There is no fear of flooding the engine, so push the

priming pump enough times to get the engine started.

Firmly turn the enrichment lever to the "Starting"

position. (The enrichment lever will be turned to

"clockwise direction" according to "Arrow mark"

indicated on the lever.)

When moving the enrichment lever to the "Starting"

position, it will lock in to place.

The enrichment lever will automatically return to the

running position when the operator grasps the throttle

lever momentarily.

When the engine is already warm or on hot days, do

not turn the enrichment lever.

The recoil starter rope can cause injury if it is

released suddenly. When starting the engine,

grasp the recoil starter firmly by the grip. Do not

grasp the starter rope itself. Always control the

rope during rewind into the housing. Releasing

the starter rope suddenly may allow the rope to

whip around and injure you or damage the recoil

starting mechanism.

Pull the recoil starter grip slowly to engage the starter,

then give a short, quick pull.

NOTE

Warming Up

CAUTION

Should the engine fail to start, do not try to pull the

recoil starter grip too many times with the enrichment

lever at the "Starting" position. This will cause the fuel

to flood into the cylinder and make starting even more

difficult. In this case, set the enrichment lever to the

"Running" position and repeat the starting procedure.

After starting, vary the engine speed a few minutes.

A. Enrichment lever

After starting the engine, run the engine at the idling

speed (throttle lever position is fully CLOSED) for a few

minutes.

Allow sufficient warm-up time to prevent engine

damage. The hand held blower should be run at

idling speed for 3 to 5 minutes to allow it to warm

up before applying a load. This will allow oil to

reach all engine parts, and allow piston

clearance to reach design specifications.

OPERATING INSTRUCTIONS 19

Stopping the Engine

Ordinary Stop

Return the throttle lever to the idling position, and keep

the engine running at idling speed for a few second.

Slide the switch to the "STOP" position with "click".

Emergency Stop

Release the throttle lever.

A. Engine switch

NOTE

If adjustment is needed, it should be performed by

your authorized Kawasaki dealer.

A. Idling screw

Idling Speed

If the engine does not run at the idling speed, it may be

set too low, turn the idling adjust screw clockwise to

increase the engine idling speed. The stable idling

speed is about 3000 r/min (rpm).

Fuel Adjustment

The carburetor has been adjusted to the optimum fuel

supply at the factory. Do not reset the carburetor setting.
