But first things first: When reviewed here ER-1611 is the (largely) identical successor to the almost legendary ER 1610th Both they have as opposed to a windy competition immensely powerful linear motor which really up to the last electron in the batteries each mat if power in the head, face or elsewhere finished off. About the thumbwheel on the cutting length indestructible shaving head can be adjusted to 0.8-1.1-1.4-1.7-2.0mm in increments, taking the papers to you can leave the default one the Tooth length start value of 3 / 4mm, 5 / 9mm and 12 / 15mm fine-tune even with the thumbwheel. Anyone who uses a trick and the machine turns, ie, the moving, black instead of the fixed silver knife block for skin, can even cut even scarcer than 0.8mm, but risked u. U. a violation.
When ER-1611 Panasonic has also heard the pleas of his customers and sent the chunky, heavy transformer charger with its very unusual plugs and even more unusual operating voltage of 2.4V (and a good amp charging current) retire. The successor is the WER1611K7664, a slightly more compact multi-range power supply (hooray!) That works with 100-240V and thus also in the New Year's Eve. Anyone who wants to upgrade its ER-1610: This part also fits because (despite the higher voltage rating of 3.6V), but pulls a neat hole in the holiday budget. I. d. T., it takes only an hour, until the ER-1611 is ready for use.
The impeccable cutting performance without tangles, dragging or sticking and the perfect workmanship have already praised the previous speakers well enough - I want to criticize the somewhat confusing light organ under the start button for mode display here anyway:
Why must there an LED glow red when charging and blink when the charging end is detected? Why another LED lights up green when the batteries are empty and then flashes when the going gets tough? The two-color LED was invented. MM n. Will glow red when charging and then switch to green steady light. They like may also flash red at an early Zuneigegehen the capacity display. OK, added: Lamento at a high level.
Well, now it comes down to business: Unfortunately, Panasonic (frivolerweise inventor of NiMH batteries called "Eneloop") must be hold to advance the planned obsolescence in the latest hair trimmer. Why? Because by no means regular NiMH AA batteries or even so-called LSDs (ie those with extremely low self-discharge as the Eneloop) are installed, but a rather special design with a pin on each side, approximately 1.2mm in diameter. These pins lock into spring tongues and establish the contact. Conversion to regular cells is possible but not trivial, because it is not necessarily done with a bending of the flexible tongues: The risk of loose connections and thus frustration is given.
So how do you come to the batteries if you want to replace it? In principle, according to the procedure described in the manual. The biggest hurdle here is the black plastic cap, which is connected by fairly strong, double-sided tape with a silver lid, in which the screw is from Schnittlängenrad. Notwithstanding any other statements is also the silver plastic part (rather than aluminum) and can be damaged if too energetic lever experiments.
My advice to a boil the whole unit in the oven (50 ° C should be enough) to soften the glue enough for the black cap can be pried patient with a plastic spatula. Coarser natures do not take care of the decoration, because this black cover is not a functional part.
It continues with the two silver, metric cylinder head bolts under the shaving head, holding the latching or spring mechanism for the shaving head. This one gets most easily removed in the average length of 2 mm. Then remove the screw on the charger plug housing, the charging connector housing (labeled "Panasonic ER-1611, Made in Japan", etc.) can now be removed backwards / down. Then the two rubber caps on the rubberized base with a needle o. Ä. Remove. Including two black sheet metal screws come to light that must be removed.
Then remove the housing halves gently pry apart and at the same time the silver cap with black recording for Combs upwards. In this process, please ensure that the Schnittlängenrad is detained because under it there is a leaf spring for the locking mechanism and a spiral spring which absorbs the mechanical play at the cutting length adjustment. There are two additional screws to the fore. These are also the black sheet metal screws that were used already among the rubber caps.
Now you can carefully approach the 0.8mm position and remove the Schnittlängenrad. In this position, the spring (largely) is relaxed and can be taken out, ditto the leaf spring. (Help photos) here the installation locations noted insbesonderer the lever mechanism for cutting length adjustment. For a hobbyist that is largely self-explanatory, the lowbrow screwdriver could take longer.
In the final step, the casing halves can be separated and the battery compartment is exposed. Here, the eye is also equal to the special design with 1.2mm pins on both sides that snap into the spring tongues. Since identical replacement batteries are obscene expensive, I would advise you either to solder a 1.2mm-thin wire to the negative terminal of regular Eneloops and the spring tongues for the positive pole easy to bend so far that they produce a reliable contact or equal to modify both spring tongues accordingly. Ideally, one would have a spiral spring soldering, such as found in flashlights or other battery compartments - but unfortunately the device must then be further broken down because the resulting heat would damage the plastic holders. Another alternative would be batteries with solder tags.
I leave it to the personal craft engines, which approach is taken here.
The batteries are the way both (!) To the positive terminal on the bottom of the unit, who does it differently, risking a short circuit. Also should be mentioned that at least my ER-1610, that will not work without batteries in pure mains operation. Too bad.
Reassemble in principle in reverse order, with a droplet of silicone grease can be applied to moving parts. Granted, the story is far frickeliger, as the need to be technically and from the space here would, so I will have to deduct the ansich impeccable device a point. My ER-1610 is since its purchase anno 2009 (at that time a good 10 more expensive than the current price) in almost daily use of beard and head hair and now begins in terms of maturity slowly to weaken slightly. That's a really good report for NiCd batteries that revealed during my current decomposition. In the new model, the NiMH variant may have come to use that you can certainly use up to self-shutdown of the device, without worrying about damage.
The only drawback here is that the device then network operation requires what, is possible without problems but thanks to the long feeder cable, which plugs but also fits the clipper in the charging cradle.
If you listen at Panasonic, here's my wish list:
- Please dispose of the cryptic lighting console. Red / green for charging / charging end and flashing red for capacity reaches the end.
- A so firmly glued cap is a joke.
- Technically, there is no need to remove all the screws, without exception, which together hold the device to get to the battery compartment. This is much easier than a four-fold screwed back.
- We have a hair trimmer for professionals in front of us. Professionals do not want to pay a double-digit Euro amount for specific spare batteries and then spend two hours by investigative Schrauberei or spending for repair at the customer service risk (probably at half original price), during which the apparatus also can not be used.
- Why just another Extrawurst the battery type? After adjust the extent to Mignon design - the two pins are very unnecessary.
