OPERATING INSTRUCTIONS FOR USEWITHWEEDBLADE

• Blade Thrust is a reaction that only occurs when using ablated unit. This reaction can cause serious injury such as amputation. Carefully study this section. It is important that you understand what causes bladethrust, how you can reduce the chance of its occurring, and how you can remain in control of unit if bladethrust occurs.
  • WHAT CAUSES BLADE THRUST - Blade

Thrustcanoccurwhenthespinningblade contactsanobjecthalitdoesnotcut. This contactcauseshebladetostopforaninstant and then suddenlymoveor "thrust" away fromtheobjectthatwashit.The"thrusting" reactioncanbeviolentenoughtocausethe operatortobepropelledinanydirectionand losecontroloftheunit.Theuncontrolledunit cancauseseriousinjuryifthebladecontacts theoperatororothers.
