Description
Throttle trigger arm and cover fits 4500 (45cc), 5200 (52cc) and 5800 (58cc) Chinese chainsaws and also Plantiflex, BBT, B&Q, Silverline, Sanli, Whitemoss, Skatco, Eckman, Timbertech, Tarus and MT-9999 chainsaws. The throttle trigger arm pivots when pressed by the operator to open the carburettor throttle and increase engine speed, while the cover shields the trigger assembly from sawdust, wood chips and accidental contact. When the trigger arm cracks or breaks, throttle response becomes unreliable and the saw may stick at high revs or fail to accelerate at all a damaged cover compounds this by exposing the mechanism to debris ingress. Fitting a replacement assembly restores precise, safe throttle control during operation.
