ARMADO

TRONZADO DE TRONCOS BAJO TENSIÓN

Vea la figura 28.

Efectúe el primer corte de tronzado a 1/3 del espesor del tronco y termine con un corte de 2/3 por el lado opuesto. A medida que corta el tronco, éste tenderá a doblarse. La sierra puede resultar pellizcada o quedar colgada en el tronco si efectúa el primer corte a una profundidad mayor de 1/3 del diámetro del tronco.

Preste atención en especial a los troncos sujetos a tensión para evitar el pellizcamiento de la barra y de la cadena en la madera.

TRONZADO POR ARRIBA

Vea la figura 29.

Comience por el lado superior del tronco, con la parte inferior de la sierra puesta contra el tronco; ejerza una presión leve hacia abajo. Observe que la sierra tenderá a alejarse de usted.

TRONZADO POR ABAJO

Vea la figura 30.

Comience por el lado inferior del tronco, con la parte superior de la sierra puesta contra el tronco; ejerza una presión leve hacia arriba. Durante el tronzado por abajo, la sierra tenderá a venirse hacia usted. Esté preparado para esta reacción y sujete firmemente la sierra para conservar el control de la misma.
