Notes during operation

Cautions

 

 

Exhaust contains toxic ingredients. Do not

run the engine in closed places or places with poor ven-

tilation for a long time.

Cautions

 

 

The liquor (dilute sulfuric acid) in Battery is

strong corrosive; it may burn the skin and blind the eyes

when it contacts them. In case of contact, please wash it

with a great deal of clear water immediately, and receive

medical treatment in hospital. Besides, please also wash

it by a great deal of clear when it contacts the clothes, for

avoiding skin burn. The Battery and Battery liquor must

be stored strictly, away from where children can touch.

Cautions 

 

 

 

 

 

 

 

 

 

 

Uniform (pilot uniform etc), cap, safety boots

suitable for the operation must be worn, and the safety

articles such as dustproof goggles, dustproof respirator

and gloves shall be worn for protection when necessary.

Cautions 

 

 

 

 

 

 When the engine just stops, the tempera-

ture of engine, muffler is still high; please do not touch

them with bare hands, for avoiding burn. Please wear

uniform with long sleeves as well as gloves when

maintaining.

Cautions 

  

  

  

  

  

The coolant is poisonous, please do not

drink it, do not let it contact the skin, eyes neither clothes.

In case it contacts the skin or clothes, please suds it

immediately. When it contacts the eyes, please wash it

thoroughly with a great deal of clear water immediately,

and receive medical treatment in hospital. In case the

coolant is drunk by mistake, please try to vomit it out, and

receive medical treatment immediately after gargling. The

coolant must be stored strictly, away from where children

can touch.

Cautions

:

 

No smoking or naked fire is allowed at the

operation site, for the gasoline is combustible. Not only

flames, but electric sparks shall be avoided. Besides,

the vapored gasoline is explosive, please operate it in

the place with nice ventilation.

Cautions  

The Battery may produce combustible and

explosive hydrogen when it is being charged. So it

may explode if there is flame or electric spark. So

please charge it in the place with nice ventilation.

Cautions 

 

do not let the turning or movable pieces

such as rear wheel, clutch etc clip your hands or

clothes when maintaining.

Cautions 

The asbestos dust on the brake drum is

carcinogenic is breathed in. Do not clean off the dust

with compressed air. Use cleaning detergent to avoid

dust proliferation.

Cautions 

The personnel shall make them be aware of

each other from time to time when operating, for safety

confirmation.

Cautions to disassembly, assembly

     The parts, lubricant and grease must adopt the

pure parts of Chunfeng Brand or recommendation.

     The parts of each system shall be arranged and

stored separately, so that the parts can be as-

sembled to the original places.

      The parts shall be washed and the cleanser shall

be blown away by compressed air prior to deter-

mination when they are disassembled and

inspected. The working surface shall be lubricated

before assembly.

      Insert and arrange the bolts one by one and make

sure the insertion volume of each bolt is equal

before inserting them, when the bolt length is

unidentified.

      Please clean the dirt, dusts on the vehicle before

maintenance.

      The gasket, O-ring, piston pin retainer and split

pin must be renewed after disassembly.

      The elastic retainer will deform if it is opened too

wide upon disassembly, then it will easily fall off

when assembled again. Please do not use the

elastic retainer that is already loose and without

elasticity.

     Inspect the necessary sites upon disassembly,

measure the relevant data, so that the original

status can be resumed after assembly.

      The fasteners such as bolts, nuts and screws shall

be pre-fastened, and then be fastened on the di-

agonal according to regulated fastening torque in

the principle of from big to small, from inside to

outside.

1-4

 

 The rubber parts shall be checked whether they are

aged upon disassembly, renew them in advance when

necessary. Besides, try not to make volatile oil, grease

etc attach on the rubber parts, for they are not resistant to

corrosion of gasoline or kerosene.

 

Proper special tools must be applied to the operations

which require special tools

             The inside or outside track of ball bearing shall

be turned manually, for confirming the flexibility and

smoothness of turning.

The parts that are loose axially or radially shall be

renewed.

The parts that are unsmooth shall be washed with

oil, and the parts that are not repaired after washing shall

be renewed (the dual-side dustproof type cannot be

washed)

Press it into the machine or axis, and the bearing

shall be renewed if the pressed part is not tight enough.

Do not let the bearing race turn back when blowing the

ball bearing by compressed air after washing. If the bear-

ing race turns back, its high back turning speed will be

beyond the limit that may result in damage of bearing.

The bearing shall be lubricated with engine oil or grease

before assembly.

The recommended lubricating grease must be applied

or injected in the appointed positions.

When disassembling the pressed ball bearing, the dis-

assembled bearing must not be used again if the balls

are forced for disassembly.

The installation direction of single-sided dustproof bear-

ing shall be paid attention to upon disassembly. The sur-

face of open-type or dual-side dustproof bearing that is

with the sign of manufacturer, dimensions shall face

outside upon installation.

The side with chamfer shall face the impact direction

when installing the circlip. The circlip that is loose al-

ready or without elasticity shall not be used again. Rotate

the circlip after assembly, for confirming that it is installed

in the groove properly.

Each fastening part must be inspected whether they are

tightened and work well after assembly.

Install oil seal with the side of manufacturer’s mark

outward.

.do not fold or scratch the oil seal lip.

.apply grease to the oil seal lip before assembling.

 Do not mix mud or dust into engine or the hydraulic brake

system.

Do not twist or bend the cables too much.Distorted or

damaged cables may cause poor operation.

 Brake fluid and coolant may damage coating, plastic and

rubber parts. Flush these parts with water if splashed.

When installing pipes, insert the pipe till the end. Fit the

pipe clip, if any, into the groove. Replace the pipes or

hoses that cannot be tightened.

Clean the gaskets and washers of the engine cases

before assembling. Remove the scratches on the con-

tact surfaces by polishing evenly with an oilstone.

When assembling the parts of protection caps, insert the

caps to the grooves, if any.
