This wrench uses a light but powerful four-stroke motor. The choice was a 43cc Makita motor. On the basis of such an engine and was built four-stroke petrol wrench "Spirit 1-4". Its power is 20% higher than that of the previous two-stroke model.
Spirit impact wrenches have a closed-loop lubrication system not only for the gearbox but also for the impact mechanism. As a result, when working hard, the liquid oil effectively washes the impacting parts of the striker and anvil, dissipates excessive heat, preserving strength and preventing wear.
The advantages of the four-stroke engine are:
lower fuel consumption - saving petrol
no oil fumes - cleaner air
no need to prepare petrol mixture - no worries about buying special oil
less frequent spark plug changes
power is higher
