CUTTING WITH A NYLON HEAD Line head rotates in a counter CLOCKWISE direction.The CUT-OFF KNIFE will be on the right side of the debris shield (See fig.11). For nearly all cutting, it is good to tilt the line head so that contact is made on the part of the line circle where the line is moving away from you and the debris shield. This results in the debris being thrown away from you. Fig.11 Fig.12 WARNING: The proper debris shield must be in place on the unit when nylon cutting line is used.
Scalping and edging (See fig.14,15) WARNING: Do not use a steel blade for edging or scalping. Both of these are done with the line head tilted at a steep angle. Scalping is removing top growth.Edging is trimming the grass back where it has spread over a sidewalk or drive way. During both edging and scalping, hold the unit a steep angle and in a position where the debris, and any dislodging dirt and stones, will not come back towards you even if it ricochets off the hard surface.
Blade thrust is the reaction which may occur when the spinning blade contacts anything it cannot cut.This contact may cause the blade to stop for an instant ?and suddenly "thrust" the unit away from the object that was hit.This reaction can be violent enough to cause the operator to lose control of the unit.Blade thrust may occur without warning if the blade snags ,stalls or binds.
EXHAUST PORT AND SILENCER Depending on the type of fuel used,the type and amount of oil used,and/or your operating conditions,the exhaust port and silencer may become blocked with carbon deposits.Ifyou notice a power loss with your petrol powered tool. A qualified service technician will need to remove these deposits to restore performance. ADJUSTING CARBURETOR NOTE: Do not adjust carburetor unless necessary.
