Dear users:
Hello! Thank you for choosing the LaiDong brand diesel engine.
The diesel engine should have for a long time reliable good performance , it is a foundation to design and make, it is a key to maintain and use. So you must read fields LaiDong" the diesel engine use and maintain maintaining the manual " and " guarantee the manual " in detail. Use and maintain on request strictly.
First, operate precautions of maintaining
Check whether the engine oil is within the fixed engine oil scale scale mark before 1 is started, whether engine oil quality fulfils requirements, guarantee to annotate the engine oil on request , check whether the circulating water fills it up.
2 should idle to dally warm 15 car about minute , observe engine oil pressure normal rapidly before driving a vehicle, observe cooling water top up , circulation normal , leak , oil spill and leak gas the phenomenon again.
3 cold car is it is it have 10-15 the more first to go to set out on a journey , transport vehicle speed per hour should be limited to 40 kilometers each time, the speed per hour of tractor should be limited to 15 kilometers, when the temperature reaches more than 75 degrees Centigrade more normal speed goes , can guarantee to do it in this way such parts as the cylinder jacket , axle bush ,etc. get the good and abundant lubrication, make every sport rub the surface and rub out the surface of surface of the mirror, thus improve the service life of the diesel engine by a large margin .
4 pays attention to observing and smell is normal for the engine oil pressure , temperature , sound , cigarette degree of the diesel engine while driving a vehicle, unusual should is it check to park immediately , can just continue going after fixing a breakdown, it will make the trouble damaged and expanded improperly otherwise operate.
5 must carry on break-in according to the fixed demand . Because machined surface smooth finish store in full of bumps and holes too on the microcosmic fortunately, break-in is to the protruding course of pieces of passivation of machine tooling in fact, thus rub out protruding one with good wearability through the passivation.
6 will check every interface of the intake pipe and leak gas with the damage frequently. Leak gas and damage, make with dust air the process will filter and enter the combustion chamber directly, aggravate the wearing and tearing of jar set , piston and piston-ring.
7 is it go 5000 change one CD grade engine oil , set oil free should go on when engine oil temperature is higher each time to propose generally speaking, set oil spiral shell free fill on one hour don't twist, in order to put the net my oil with impurity.
8 paper air filters should go 2500 kilometers to wash once and strain core each time, 5000 kilometers change once and strain core, should be shortenned and changed time when the dust amount is bigger. Air filter core must buy filter paper quality fine , glue cushion elasticity kind normal product. Top glue cushion is it is it go to level to exposed to to want when installing, underpart add glue cushion peaceful cushion is it strain core put upper and lower terminal surface seal good well to guarantee, must not is it load paper strain plastics of core strain core to leak at the same time(commonly called as thick to strain core), strain the core thickly and bear 60% of the air filter amount. The oil bath type air filter guarantees to annotate the engine oil in accordance with the instructions of scale , and often wash , change the engine oil .
9 step on throttle raise speed and is it is it is it can damage parts to moderate suddenly to brake to step on suddenly fast suddenly. Half step on from is it go to moderate jointly or long time step on from is it can lead to the fact the bent axle to wear and tear the organism to equal to.
10 cooling water must be used and softenned water, forbid using the hard water (well water , spring), if use needing to be softenned and dealt with.
The adjustment of 11 high-pressure oil pumps needs professional personnel to go on, do not allow to heighten and use the rotational speed or the amount of oil strengthened .
12 users can't repack at will , otherwise the one that cause is responsible for the loss by oneself; If there are special demands , can order alone .
When being frozen, cooling water should annotate the anti-icing fluid one winter. Annotate anti-icing fluid , should turn on diesel engine and water tank turn on the water the valve at the same time when turning on the water, turn on the water under the idle rapidly state of operating. Water can damage the organism and water pump by frost in the organism.
Second, how to get the three guarantees service
The address of service station registering, get in touch with service station nearby while " guaranteeing the manual " in a reference.
2 moves and stays some business personnel and gets in touch with the local fields lying fallow in rotation directly.
3 dials the fields lying fallow in rotation and moves the service hotline: 0535-7225318.
Third , one of the following situations will not three wrap up
1 does not have three guarantees evidence, the three guarantees evidence has been altered or the odometer is adjusted.
Trouble caused that 2 or overloaded seriously for a long time according to fixed break-in .
3 has not annotated the fuel , lubricating oil , cooling water according to the regulation of the manual . Have not maintained in 100 hours and 500 hours .
4 lack of water is it draw jar or add cooling water pass worried to is it split relevant parts to surge to lead to the fact.
5 has not turned on the water and damaged the organism or other parts by frost.
6 use inferior and unclean engine oil or lack engine oil and engine oil pressure pass low cause take the tile.
Note: Should pay attention to the relation between engine oil grade and temperature while annotating the engine oil.
7 enter angry to cause jar suit , piston and piston-ring wear and tear in early days while being unclean.
8 use inferior diesel oil card die oil head, or charcoal too much to cause the piston-ring to rupture.
9 preheat for a long time, is it produce electric heat fill in or is it burn out the starter to start for a long time to cook.
10 goes 20000 kilometers (or 8 months ) because the connecting rod bolt become flexible the connecting rod bolt caused rupture .
11 keep original state of damaging or request for agreement to seller , persons who repair after breaking down, it makes the trouble reason unable to make the technical appraisement to handle by oneself.
Fourth, important suggestion of three guarantees
1 user is it is it purchase to maintenance personal car (machine ) invoice and fields lying fallow in rotation move diesel engine " guarantee the manual " to provide to want while accepting the three guarantees service.
2 three guarantees time limit and distance travelled any item is it is it go beyond the three guarantees one to stipulate to go beyond.
3 when the odometer can't be measured accurately for some reason, go one hour with day, speed 40 kilos per hour calculate three guarantees effective mileage on average, the unit converts the mileage of three guarantees according to this method without exception while repacking .
4 users refuse dismantling examining normally of the maintenance personal , will be deemed to give up the three guarantees right automatically.
The paid service of 5 maintenance personals must provide receipts to you while collecting the charges, otherwise you have the right to refuse payment.
