CAUTION

Keep belts clean of foreign material that may cause slippage. Never dress belts as this can cause premature failure.

Ideal V-Belt tension is the lowest tension at which the belt will not slip under peak load conditions.

The V-belt tension on this saw is controlled by the hydraulic system that actuates the Blade Shaft Engage/Disengage System. Hydraulic pressure exerted on the engine tilt cylinder applies force on the Belt Drive System to engage Bladeshaft rotation.

Engine must be at idle when engaging or dis-engaging bladeshaft drive:

To STOP Bladeshaft Rotation:

Push rocker switch labeled BLADESHAFT forward. Engine will tilt forward, dis-engaging the drive belt.
