Ts55r shocks from tool and guide rail

[Nippychippy]

Ye dean got my dust port last week I haven't got around to trying it just give them a call

Dean it's the dust port on the saw. I had mine changed on site by festool last year and not had any shocks since. Apparently they had a batch of them where the graphite content in the plastic was too low. This made them less conductive

Does anyone know if this can cause damage to a connected CT as static is known to be a source of damage to extractors?

Just a guess but if the static is being discharged to the user then it wouldn't be getting to the ct , if it was then I would have thought there would be no static left in the saw

I got a static shock at the roadshow a few weeks back. I was trying out the new dust collection gizmo for drilling holes in walls. Used the new cordless sds with it and when I touched the metal ring on the dust collector whilst the vac was running I got a static shock.

Shocking !!!

 

[Deansocial]

It really shows off the static problem doesnt it.

For those who don't see it in the video it is at about 7 seconds.  Look at the knuckle lowest in the image and closest to the blade guard.

Yep that would help if i pointed that out lol

It sparks 9 times. It is aplified by not having an antistatic hose but still happens with 1 fitted

 

[Deansocial]

Using it today keeping knuckles away from the metal i could see sparks jumping from the metal blade casing to the rubber on the hose.

My sword saw gives of some heavy static shocks. I reckoned it was because I was cutting rigid foam insulation. It's a good zap not unlike an ht lead from a small motor.

My saw also shocks pretty strong and will do it several times while using it.  Didn't do it until after I had it for 4 months or so.  I'm using an AS hose and CT48 with the saw plugged into the CT and the CT plugged into a grounded outlet.  I replaced the electrical service to the house and all the panels before we moved in and have a new circuit that I'm using.  I know everything is properly grounded from both ground rods (2 required here) all the way to the outlet.  I thought it was due to low humidity but it sounds like that might not be the case.

Greg,  I would suggest that you contact Festool USA regarding your situation.

I'm a little unclear what the purpose is that this discussion has turned toward. There isn't anything wrong with the tool, and there isn't anything wrong with the vac. The operator is simply electrically spanning a static generator. Even though the vac is dissipating one side of the static generator, the operator is being influenced by the potential on the other side of the generator, namely the sheet of MDF. There will be a voltage difference, and the only way around that would be to ground your sheet of plywood too (which isn't really feasible).

Assuming that the saw is connected to a correctly wired 3 pin outlet shouldn't the earth wire on the saw be dissipating the static?

It's a double-insulated tool with only a 2-prong plug. It is not grounded. Moreover, a requirement for a double-insulated tool is that the operator's handle MUST be electrically isolated from all metal parts of the tool--that includes the port where the dust extraction connects to the metal blade housing.

 

[Bohdan]

Obviously a case where double insulated is not appropriate.

I used a ts75 for 7 years or so and never got a static shock, why so often with the ts55r? Verything else is the same.

 

[Rick Christopherson]

Because your hand is farther away from the blade housing.

 

[Deansocial]

Because your hand is farther away from the blade housing.

But regardless how far away my hand is i still have to pick the rail up after. That gives a bloody good shock too.
