That the trimmer served faithfully long time, it is necessary to show serious approach to its service. One of important aspects of technical maintenance of the trimmer is the choice of oil for the engine.
Trimmers became irreplaceable assistants on many personal plots. They are capable to perform functions of the whole complex of the hand garden tools used for kosheniye of grass, cutting of bushes or trees and even for snow cleaning. Modern mechanisms differ in reliability and long life cycle which depends as well on application of the necessary type of oil. Owners of petrol saws and similar units will have no difficulties with service of the trimmer: oil for the majority of two-stroke engines is used identical.
For two-stroke engines
The majority of trimmers have the two-stroke engine which though has the simplest device, but nevertheless requires close attention at service. For filling of two-stroke engines mix of gasoline and oil in certain proportion is used. This ratio plays crucial role - it needs to be specified upon purchase of the trimmer. As for oil, practically any lubricant with marking 2T approaches. Of course, producers of expensive tool demand use of fuel and lubricants on the established specification, but such oils as Mobil 2T+, Liqui Moly Motorrad 2T or Castrol Power1 Racing will be suitable for the majority of trimmers. Average portion of additive of oil - about 20 g on 1 l, however over time amount of lubricant it is possible to determine by practical consideration by availability of deposit on candle and extent of pollution of the carburetor.
For trimmers with the four-stroke motor
Four-stroke engines have separate capacity for oil flooding. Such power units are more sensitive to quality of oil, than duple though particular problems with service of trimmers with the four-stroke engine should not arise. The line of Mannol Quad or ZIC 4T oils well will be suitable for inexpensive trimmers. The trimmers which are on operation more than three years are recommended to fill in oil with the cleaning and restoring additives. In this case it is possible to use the XADO Atomic Oil 4T oil containing the whole complex of additives and differing in the increased viscosity - 10W60. In most cases are suitable for trimmers polusinteticheskiye oils of average viscosity 10W40 of the middle price range.
Whether oil replacement is required?
If the trimmer does not experience extreme strain during the work, the term of operation of oil is approximately comparable to life cycle of the engine. Often only control of level and timely filling-up of oil is required. However the condition of lubricant in the engine needs to be controlled regarding blackening, availability of suspension and other signs of aging from time to time. In these cases it is recommended to replace oil completely.
