Funkce

1.Dobrý systém absorpce otřesů: Díky němu se obsluha bude cítit pohodlně a zmírní únavu.

Způsob realizace: prostřednictvím "systému kontroly vibrací"; prostřednictvím měkké gumové rukojeti pro zvýšení pohodlí držení;

Bezpečný provoz

1. Osobní ochrana při používání elektrického kladiva

1.TheoperatorshouldwearprotectiveglassestoprotecttheeyesandfaceWhenworkingupwards,wearaprotectivemask.

2.Během dlouhodobého provozu je třeba zapojit špunty do uší, aby se snížil vliv hluku.

3. Vrták je po dlouhodobém provozu v horkém stavu, při výměně byste měli dávat pozor, abyste si spálili kůži.

4.Whenworking,youshouldusesidehandlesandoperatewithbothhandstopreventthereactionforcefromsprainingyourarmswhenblockingtherotor.

5.StandingontheladderWorkorworkathighplacesshouldtakemeasurestofallfromhighplaces,andladdersshouldbesupportedbygroundpersonnel.

2.Před prací je třeba věnovat pozornost

2,thedrillbitandtheclampTheholdershouldbeadaptedandproperlyinstalled.

3.Při vrtání stěn, stropů a podlah nejprve ověřte, zda jsou zakopané kabely nebo trubky.

4.Whenworkingathighplaces,payfullattentiontothesafetyofobjectsandpedestriansbelow,andsetupwarningsignswhennecessary.

Použití

1. Předprovozní kontroly by měly splňovat následující požadavky:

1. Rukojeti skořepiny by neměly prasknout ani se poškodit;

2.Kabelové šňůry a zástrčky jsou nepoškozené,spínání je normální,ochranné nulové připojení je správné,spolehlivé;

3.Theprotectivecoversofeachpartarecompleteandfirm,andtheelectricalprotectiondeviceisreliable.

2.Afterthemachineisstarted,itshouldrunwithoutload,anditshouldbecheckedandconfirmedthatthemachinelinkageisflexibleandunimpeded.Duringoperation,theafterburnershouldbesteadyandnottoostrong.
