態から、把手９を持つて引出しながら始動ロープ
により起動することができることになる。 1 to 5, the worker carries out the work while wearing the brush cutter A as shown in FIG. 1, but when starting the engine E, the flange 10 of the starting device B is opened. 1 and each protrusion 12 is aligned with the engagement groove 8a of each engagement part 8, and when the activation device B is rotated as it is, each protrusion 12 will fit inside the engagement groove 8a. The starting device B can be mounted on the same axis, and the rotating body 1 can be attached to the engaging pin 5 of the inner starting section C.
From the state in which the engaging claw 11' that protrudes and retracts from 1 can be engaged, it is possible to start the engine using the starting rope while holding the handle 9 and pulling it out.
その場合、始動ロープにより起動装置Ｂが回転
方向に回るよう力をかけられるが、各突起１２が
各係合部８に係合して固定されたままとなる。 In that case, a force is applied by the starting rope to rotate the starting device B in the rotational direction, but each protrusion 12 engages with each engaging portion 8 and remains fixed.
そのようにしてエンジンＥが始動すると、起動

外したので軽量となり、その起動装置Ｂの部分の
出張りがなくなつて刈払機Ａをその分だけ余裕を
もつて操作することができ、また、カバー２を開
口部１に被着して安全構造にすることができると
ともに、網１３を通して吸気することができ。 Therefore, since the starting device B is removed, the brush cutter A becomes lighter in weight, and since there is no longer a protrusion on the starting device B, the brush cutter A can be operated with more leeway. The cover 2 can be attached to the opening 1 to provide a safety structure, and air can be taken in through the mesh 13.
なお、取外した起動装置Ｂは収納箱等に入れて
おくと、従来のように作業にともなつて起動装置
に塵埃が付着するといつたことなく収納しておく
ことができ、また、単一の起動装置でもつて複数
の作業機に兼用させて使用することもできる。 In addition, if you put the removed starter B in a storage box or the like, you can store it without worrying about dust getting on the starter device during work, and you can also The starting device can also be used for multiple work machines.
