The use of the machine may be

hazardous. The impeller rotating

in the volute case may cause harm

if you try to touch it. It is important

that you read & fully understand the

following safety precautions and

warning.

SAFETY PRECAUTION

Do not lend or rent your sprayer-

duster without the Owner ’s

Manual. Be sure that anyone

using your sprayer-duster reads

and understands the information

contained in this manual.

Safe use of the Tomahawk Sprayer-Duster:

1.The operator

The operator must be in good physical

condition and mental health.

The operator must not use the machine if:

(1) Under the influence of a mind altering

substance.

3. Using the Tomahawk Sprayer-Duster

Starting the engine

(1) Set the throttle handle to the stop

position before starting the engine, otherwise

chemical will be sprayed when starting engine.

(2) Be sure no one stands in front of

nozzle, even though the handle is set,

to stop, residual materials in pipe will blow out.

Spray Operation

(1)

wind is recommended. For example,

Operation during cool weather with little

in the early morning or in the late afternoon.

This can reduce the evaporation and drift of

chemicals and improve spraying efficiency.

(2) Operator should face his/her back to wind.

(3) If your mouth or eyes are spattered

with chemicals, wash them with clean water

and go to see a doctor immediately.

(4) If the operator has a headache or

dizziness, stop working at once and go to

see a doctor immediately.

2. Main Application

This Tomahawk Mist-Duster is the ultimate

portable tool for prevention of diseases and

for plant protection. It is mainly used in

prevention and cure of diseases and pests

of plants such as cotton, rice, wheat,

fruit trees, tea trees, banana trees, etc. It

can also be used for chemical weeding,

epidemic prevention, sanitation protection in

cities, etc.

3. Main Features

3.1 This machine adopts a gear structure to

decrease speed, so it is very durable.

3.2 The main part is the plunger pump

of two directions’ type. The structure is

simple and compact, so it is easy for the

maintenance.

3.3 This machine has high pressure, big

flow and good efficiency, so spraying and

and dusting is very effective.

3.4 Three nozzles help propel the spray/dust

in a wide range.

4. Assembly for varieties of

operating condition

(1) Assembly for spraying

a.Assembly in chemical tank Remove the

lower cover of chemical tank,change into the

pressing lid which is connected with rubber

tube(do not forget to put on the sealing

ring,as Fig.2.).Connect the lid to the rubber

tube as shown in Fig.1.

(3)Anti-electrostatic installation

Dusting or spreading dust chemical

may caus e the el ec tr ostatics,that is

related to the factors,such as the kind of

chemicals,air temperature,air humidity,etc.

In order to prevent ectrostatics,please use

the attachment-insurance chain.When

the air becomes dryer,the electrostatic is

more serious,in particular when the long

membranous tube for dusting and granules

spreading is used,electrostatic will often

happen.Please pay attention.

One end of insurance chain is inserted into

jet pipe,vibrated freely and touched to the

ground.Connect another end with conducting

chain on bend pipe by screw.

Assembly as Fig.4.

(2) Assembly for Dusting

Remove the chemical tank, remove the

inlet rubber tube,outlet rubber tube, suction

strainer,spraying lid plate,pressing lid and

change for lower lid of chemical

tank,then connect the dusting pipe as Fig.4.

5. Engine Rotation

(1)Check

a.Check whether the spark plug and all

the connecting pieces are tightened.

b.Checking whether the cooling air channel

is clogged. If so, the engine will be over

heated.

the dirt will reduce the amount of air drawn

in. The engine will not run well and fuel will

be wasted.

d.Check whether the gap of the sparking

plug is 0.6～0.7mm.

e.Pull the starter 2 or 3 times, checkwhether

the engine rotates normally.

(2)Fueling

a.The fuel for this machine is a mixture of

gasoline No.70 or No.90 and 2-stroke oil.

Incorrect gasoline, oil and mixture may damage

the engine.

b.Never fuel the engine when it is hot or

running.

c.When fueling, never remove the strainer.

(3)Adding chemicals

a.During spraying operation, the hose

must be shut,see Fig. 5.

During dusting operation,dusting valve

throttle and fuel lever should be on the

off position,other-wise,the machine will

still release chemicals.

Fig 4

b.As powdered chemicals can easily

solidify, the chemicals should not be in the

chemical tank for a long time.

c.While spraying,the chemical tank lid

should be turned tightly.After adding

powder chemical,please clean the threading

on the chemical tank mouth,then turn on the lid

so it is tightly secured.

(4) Starting Cold

Please operate according to the following

procedures:

a.Press oil cup 2-3 times until it fills with gasoline

and see Fig.6.

b.Set the throttle handle to the stop position,see

Fig.8.

c.Set the choker on the full position,see Fig.7.

d.Pull the starter for a few times and let it

retract slowly.Do not let the handle to retract

freely to avoid damage of the starter.

Fig 8

e.Close the choker and pull starter handle

f.After starting the engine,open choker fully.

g.Let the engine run at low speed for 2-3

minutes,then start the spraying or dusting

operation.

Fig 6

(6)Stopping the engine

a.Set the two control handles to their lowest

positions until the engine stops.

then stop the machine.

c.Having finished working, turn off the fuel

switch.

Note: While the engine is running, the hose

must be mounted to the machine, otherwise

cooling air will be reduced and this can

damage the engine.

(5)Starting the engine warm

a.Leave the choke fully open.

b.If the engine draws in too much fuel.Leave

the fuel switch fully closed ,pull the starter 5-6

times.Then start the engine as explained above.

6.Misting/Dusting

-9-

(1)Misting.Loosen the pressing lid,regulate

the length of the nozzle opening to meet

your optimal leves of misting.Turn the
