Valmiki Ramayana Sundara Kanda Sarga 44 Shloka 15

शरैः arrows, पूरिततनु: the body was filled, सः that, महता intense, क्रोधेन with anger, वृतः endowed, वेगितः speedily, तं परिघमेव the same iron spear, गृह्य seized, भ्रामयामास started whirling.

Hanuman filled with arrows all over his body, seized an iron spear (which he made use of in the initial battle) and impetuously spun it in intense anger.
