CAUTION: Do not forget to mount spring (5). MOUNTING OF HANDLE For machines with loop handle – Fix a barrier to the left side of the machine together with the handle for operator protection. – Do not adjust position of the loop handle too close to the control grip. Keep not less than 250 mm distance between the handle and the grip. (a distance collar is provided for this purpose.) (1) (2) (3) (4) (5) Engine Engine 11 To meet the applicable safety provisions, only the tool/ protector combinations as indicated in the table must be used. Be sure to use genuine DOLMAR cutter blades or nylon cutting head. – The cutter blade must be well polished, free of cracks or breakage. If the cutter blade hits against a stone during operation, stop the engine and check the blade immediately. – Polish or replace the cutter blade every three hours of operation. – If the nylon cutting head hits against a stone during operation, stop the engine and check the nylon cutting head immediately. CAUTION: The appropriate protector must always be installed, for your own safety and in order to comply with accidentprevention regulations. Operation of the equipment without the guard being in place is not permitted. The outside diameter of the cutter blade must be 230 mm (9-1/16”). Never use any blades surpassing 230 mm (9-1/16”) in outside diameter. Metal blade Protector for metal blades Nylon cutting head Protector for nylon cutting head (3) (2) (1) MOUNTING OF PROTECTOR – In use of the metal blade, fix the protector (3) to the clamp (2) with two bolts M6 x 30 (1). NOTE: Tighten the right and left bolts evenly so that the gap between the clamp (2) and the protector (3) will be constant. Otherwise, the protector sometimes may not function as specified. (3) (4) – In cases where the nylon cord cutter is to be used, be sure to mount the nylon cord cutter protector (4) onto the metal blade protector (3). – Mount the nylon cord cutter protector (4) by sliding it into place from the flank of the metal blade protector (3) as shown. – Remove tape adhered to cutter, which cuts nylon cord, on nylon cord cutter protector (4). CAUTION: Be sure to push in nylon cord cutter protector (4) until it is fully inserted. Take care not to injure yourself on the cutter for cutting the nylon cord. – To remove the nylon cord cutter protector (4), apply a hex wrench into the notch on the metal blade protector (3), push it in and meanwhile slide the nylon cord cutter protector (4). Hex wrench 12 Turn the machine upside down, and you can replace the cutter blade or nylon cutting head easily. – Insert the hex wrench through the hole in the gear case and rotate the receiver washer (4) until it is locked with the hex wrench. – Loosen the nut (1) (left-hand thread) with the socket wrench and remove the nut (1), cup (2), and clamp washer (3). Rotation Hex wrench MOUNTING OF CUTTER BLADE OR NYLON CUTTING HEAD Mounting of cutterblade with the hex wrench still in place – Mount the cutter blade onto the shaft so that the guide of the receiver washer (4) fits in the arbor hole in the cutter blade. Install the clamp washer (3), cup (2), and secure the cutter blade with the nut (1). [Tightening torque: 13 - 23 N-m] NOTE: Always wear gloves when handling the cutter blade. NOTE: The cutter blade-fastening nut (with spring washer) is a consumable part. If there appears any wear or deformation on the spring washer, replace the nut. Mounting of nylon cutting head – The clamp washer (3), cup (2), and nut (1) are not necessary for mounting the nylon cutting head. The nylon cutting head should go on top of the receiver washer (4). – Insert the hex wrench through the hole in the gear case and rotate the receiver washer (4) until it is locked with the hex wrench. – Then screw the nylon cutting head onto the shaft by turning it counterclockwise. – Remove the hex wrench. – Make sure that the blade is the left way up.
