Характеристики

1.Добра система за поглъщане на удари: Тя може да накара оператора да се чувства комфортно и да облекчи умората.

Начин на реализация: чрез "системата за контрол на вибрациите"; чрез меката гумена дръжка за повишаване на комфорта при държане;

Безопасна работа

1.Лична защита при използване на електрическа чанта

1.TheoperatorshouldwearprotectiveglassestoprotecttheeyesandfaceWhenworkingupwards,wearaprotectivemask.

2.Тепите за уши трябва да бъдат включени по време на продължителна работа, за да се намали влиянието на шума.

3.Свредлото е в горещо състояние след продължителна работа, трябва да обърнете внимание да не изгорите кожата си при смяна.
