The slicers require usually two sources of lubrication. Like the majority of the engines of two-race, the engine is lubricated by its fuel, which contains approximately 2 the oil of the ~ 5% (according to the model) dissolved in the fuel. Since this mixture is strongly flammable, a completely separate oil tank is used for the external lubrication of the blade and the chain. This last oil is exhausted quickly because it tends to being thrown in addition to chain by the centrifugal force.

This tank does not maintain remakes the full one, or by using an oil of incorrect viscosity, a source common of damage to the saws and tends to lead to the chain releasing itself from the bar. With some types of wood, the operator will have from time to time to stop and to disconnect the holes where oil is distributed to the bar of chain and guide the filter of air intake tends to block with the sawdust. This must be cleaned from time to time, but is not a problem during the normal operation.

Many operators of saw clean it with water the gasoline, although the manufacturers recommend to employ the compressed air to blow dust in addition to mesh of filter of the interior, or heat and soapy, and then left to dry with the air. If these resources are not available, pure, the clean gasoline should be employed, otherwise residual oil on the filter will compose blocks it to him still faster. Chains must be maintained very pointed to carry out well. This can be done with a round file or a gauge (without removing the chain of the saw), or with an electric gauge of setting specialized the chain being crossed saw.

The gauges help to make sure that each face of cutting is maintained with the correct angles, which are carefully balanced to maximize the effectiveness of the saw. The suitable hand-setting can produce a better result, but the electric sharpening machines are faster, in particular by sharpening the very matt chains (particularly those which were subjected to dirtiness, metal or the rocks). Blades of carbide slicer cannot be sharpened by the conventional sharpening machines and must be sharpened by a diamond sharpening machine.
