WARNING - THIS STUFF IS STILL LIVE UNLESS THE BATTERY IS REMOVED
!

***I am posting this here due to the general interest in battery
powered outdoor powered equipment (OPE). Many times, when I see
someone pick up a battery chainsaw (etc.) their first impulse is
to squeeze/test the trigger - not a problem with most gasoline
powered tools, where it is easy to know if the engine is
running. But it can be a real surprise with an electric tool,
especially one without a cord which may be perceived as 'safe',
less powerful, or even as a 'toy'. I explain this to anyone when
handing them a battery tool; "The tool is 'live' if the battery
is installed". I have also placed warning labels and even
'trigger locks' on some tools left out at GTGs.***
The report, below, appears to address manufacturing or design
defects, with similar hazards.
"After failing to report safety defects on its battery-powered
mowers, Black & Decker is playing a $1.575 million fine after
agreeing to a settlement with the Consumer Product Safety
Commission and U.S. Justice Dept. The settlement marks the sixth
time since 1986 that Black & Decker has paid fines for failing
to report safety defects.
This most recent fine regarding battery-powered mower defects
covers 11 years, beginning in 1998 when the company began
receiving complaints the blades wouldn’t turn off even after the
handles were released and safety key removed—and in some cases
the blades would start spontaneously. At least two consumers
were injured when blades started up while their mowers were
being cleaned. According to reports, Black & Decker identified
the defect in 2004, but waited until 2009 to report it to the
CPSC. The company agreed to a recall of the machines in 2010.
In addition to the fine, Black & Decker must maintain an
internal compliance program to ensure compliance with CPSC
safety statutes and regulations and also will develop a system
of internal controls and procedures including creating written
standards and policies, allowing confidential employee reporting
of compliance, and implementing corrective and preventive
actions when compliance deficiencies or violations are
identified."
***Pull the batteries before working on battery powered
tools!***

Never thought about this before Thanks for posting.
Would have thought there would have been some kind of safety
feature. To stop accidental trigger pull on contact and chain
movement.
Going to make a sticky for top of board.

Scary, especially with small kids wanting to emulate dad!

Each of the Oregon battery-powered tools I have, has a
dual-activation trigger: some type of 'safety' latch, button,
etc. has to be pushed, slid, depressed, etc., before the primary
trigger can be squeezed. In addition, the chain brake on the
chainsaw locks out power. But on some products, it is fairly
easy to bump the 'safety' when carrying or transporting the
tool. And frankly, the easiest place to carry these heavy,
expensive batteries is mounted in the tool.
So on a few tools, I drilled a hole for a positive lock, as
shown above. And I am training myself to consciously remove the
battery before working on the chain, etc., and not trusting the
switch.
The scary part about the B&D recall, is that the mower blade
apparently activated with the switch released and the safety key
removed. I have had a couple of woodworking tools (table saw
and router) fail with the switch in the 'ON' position due to
fine dust build up inside the switch ('Hmmmmm, . . . that blade
seems to be coasting for a really long time . . . '), so it can
happen with many tools and products. It seems that these battery
powered tools might be a special situation, because they appear
to be 'safer' than some of their corded or gas counterparts.

Lithium Battery Fail
Spare lithium battery for an e-cigarette carried loose in pants
pocket, along with keys and spare change. Pretty dramatic!

I found it aggravating but its done for safety reasons.....the
makita XCU03 chainsaw has a power button that has to pushed to
power it up for the tool to work in addition to the standard
trigger and operator presence lever. they also added an
automatic shut down to it if the trigger went unused/depressed
within 4 seconds then the power button needs pressed again,
which is really annoying when limbing a top until you realize
that just keeping the operator presence lever depressed keeps
the tool "live". Chain brake engaged also kills the power so at
least with the makita saw they have a "kill" switch on every
feature they could add one.

Some of the newer battery powered OPE I have seen require 3
points of positive activation (might be a better term for
this?),instead of just the trigger safety that we are used to.
Or they have some type of lock-out feature (key or switch),
presumably to prevent unintended activation. Might be a new
standard? Might be an EU thing?
