Winter time can be especially stressful on your car as cold temperatures and icy conditions can make the going rough during that time of the year. Hazardous road conditions, blinding snow and sub zero temperatures can put your car at risk, even leaving you stranded if you are not careful.

There is one component inside of your car that can contribute to dimming headlights, a battery unable to hold its charge and just plain difficulty starting your car on a cold winter morning. That part would be your alternator, an essential component to ensuring that your car is running right under all conditions.

“The alternator, which supplies power to your vehicle’s electrical system, works a lot harder today than it did in the past,” said Fred Padgett, Group Product Manager, Starting and Charging Products for Bosch, the world’s largest supplier of automotive parts to the automotive industry and the aftermarket. www.boschautoparts.com.

When alternators were first developed, the only tasks they were responsible for was to power the horn and the headlights. Today, car’s are much more technologically sophisticated and include a number of features that weren’t available a generation ago including navigation systems, dual zone air conditioning, entertainment systems, rear window defrosters, in-car television, refrigeration and more. Initially a 50 to 60 amp alternator would have been sufficient but today’s cars require a much more power unit, one with 130 amps or more.

According to Padgett, alternators contain diodes and built-in voltage regulators that may allow enough output to keep the “ALT” or “Check Engine” light from coming on. But output may be compromised enough that the alternator is unable to keep up with demand and is actually draining the battery to operate the vehicle. The result? Dim lights, slow wipers and turn signals, possibly a slow start condition — and ultimately, a dead battery.

Fortunately, a repair shop can check alternator output and replace it if necessary. Bosch, Padgett said, offers both new and remanufactured alternators and both carry Bosch’s free two-year emergency roadside assistance.

So before winter’s fury sidelines your car, make sure that your car is in top shape before venturing out on the road. Make sure that your vehicle’s alternator is part of that check up, something your mechanic can easily examine the next time you take your car in for service.

A router is one of the most versatile, and widely used tools on the market today; and for good reason. A router is a woodworking tool designed to rout, or mill out an area in the surface of a piece of wood, and can feasibly perform almost any kind of shaping and wood cutting application. It would be difficult to determine the application in which a router is most commonly used; they dominate edging operations, and are masterfully equip for box joining, mortising, dovetailing, dadoing, and rabbeting to name only a few.

There are several types of router available, each having individual features, benefits and their own favorite applications. The most popular types of router are the fixed-base and the plunge-base router; each of which offering their own set of pros and cons which I will attempt to shed some light upon. Beginning with the first born, the fixed-base router is a favorite of many craftsmen because of its more simple more, compact and versatile design, and its relative ease of operation. In a fixed-base router, the motor is securely clamped into the base, and has a more light weight design making it easier to work and maneuver. Built for table mounting and more stationary routing, the fixed-base router is generally better for running slots, rabbeting, and edging or molding patterns than its top heavy, plunging brother. For plunge cuts, however, the fixed-base router must be tilted or angled into the workpiece which can be a difficult procedure to master. Because the base is not fully supported as the bit enters the wood, plunge cutting can be much more difficult with a fixed-base router. These routers have simple and accurate depth adjustment systems. They must, however, be stopped and reset in between each cut.

Unlike the fixed-based router who’s configuration has changed relatively little over time, the plunge-base router is more innovatively designed. The plunge-cut router is built so its motor sits atop two spring-loaded posts; this trait allows for the vertical motion which makes the plunging action possible. The vertical movement of the router essentially “plunges” the router bit into your workpieces without ever tilting or lifting the tool enabling users to get directly into the center of a workpiece without any pre-drilling or acrobatics. With the plunge-base router, making through cuts, deep grooves and mortises is generally much easier than with its fixed-base counterpart; but although a plunge-base router is the best choice for applications requiring more and deeper cuts, it is much heavier and can be difficult to move and adjust. Understanding which router is right for you can be a long process. The information below will help you narrow down your search options and determine which router fits you best.

To begin, again, with the fixed-base router, Bosh offers a 2 HP (horse power) fixed-base router with a powerful 11 Amp motor and 25,000 RPM. This router is built with a precision centering design that makes it significantly easier to keep your bits on their intended cut line. The 8.3 lb tool is also designed with a macro and microfine bit adjustment system with resettable depth indicator for constant precision. This system provides always fast and accurate depth setting adjustment. Bosch has also incorporated a large 3-3/4 in base opening (6in. base diameter) plus a 2in. subbase opening to accept larger bits. For fast and easy template guide changes there is also a tool-free template guide adapter. The 1617 router has one-piece armature shaft for enhanced accuracy and long bit shank capacity.

Bosch’s fixed-base router also has a right or left switch location for user preference and consistency and a new dust sealed power switch for enhanced durability. The router features hardwood handles and a 10ft. flexible rubber cord. The 1617 also includes the RA1161 fixed-base system which allows for bit height adjustment from above the router table. For additional convenience the fixed-base system also has threaded holes that allow it to be mounted to the router table (in Bosch’s four hole pattern or the common three hole pattern). Bosch’s 1617 fixed-base router includes ¼in. and ½in. S.R. collet chucks, a 16mm shaft wrench, 24mm collet nut wrench, tool-free template guide adapter, a chip shield, and fixed-base.

DEWALT offers a 1-3/4 HP fixed-base router with an 11 Amp motor, 24,500 RPM, and enough power to rout out the toughest woods. The tool has an advanced microfine depth adjustment ring that provides precise depth adjustments in minute 1/64in. increments and can be adjusted vertically for a permanent switch/cordset location. This vertical movement adjusts with up and down actions rather than spinning; since the entire router doesn’t turn, the whole of the tool remains in the same position. For quick and tight-locking depth adjustments/base changes, the DW616 also has a strong and adjustable tool-free steel motor cam lock. A dust-deal keeps the switch free of dust and debris enhancing its performance, durability, and overall life. And with a right or left switch and cordset location, the user has the option to hold the switch in either the right or left hand increasing comfort and versatility. The tool’s overmolded rubber handles, and low center of gravity also contribute to the router’s best-in-class comfort, balance, and control. The router’s cordset is detachable to offer serviceability and the ability to use the same motor pack for all bases.

For easier bit changes DEWALT has built this router with a flat top – and with quick release motor latches for fast and simple motor pack removal. The router also has long, self-releasing, eight-slotted collets for better bit retention and elimination of frozen, or stuck bits. A clear LEXAN subbase (polycarbonate material specially developed for strength and impact resistance) delivers enhanced base durability and bit visibility, and also accepts standard template guide bushings. The subbase additionally has a concentricity gauge for best-in-class routing accuracy. With a heavy-duty, precision machined, die-cast aluminum base and motor housing – the tool is supremely durable, and weighs only 7.1 lbs. DEWALT’s DW616 fixed-base router includes a motor pack, fixed-base, concentricity gauge, ¼ and ½ in collets, and two wrenches. The router is also available to purchase as a kit (DW616K), which includes the above with DEWALT’s heavy-duty kit box.

As for the plunge router, Makita offers a 3-1/4 in plunge-router with a powerful 15 Amp motor and variable speed option from 9,000 – 23,000 RPM. The router’s variable speed option ensures greater routing precision and always accurate projects. The router also has a pivoting multiple depth adjustment knob with three preset plunge depths, and a top handle depth adjustment which sets the tool to any specific routing depth. For easy penetration into your workpiece, the router also has a 0 – 2-3/8 in plunge depth capacity. Makita has incorporated an electric brake for fast bit stoppage which also helps to prevent accidental marring of working materials. And, with an electronic speed control, the tool maintains constant speed even under load. The 3612C plunge-router also has a bit deflector to keep chips and debris away from the operator and workpiece. The tool weighs 13.2 lbs, is double insulated, and has a strong, all ball bearing construction to extend the tool’s overall life. Having a shaft lock for quick and easy bit changes, and a soft start feature for smoother start-ups, Makita’s plunge router is equip to handle all your plunge-routing needs. The 3612C includes a ¼ in collet sleeve, ½ in collet cone, and wrench.

DEWALT also offers a heavy-duty 3 HP plunge-router with a 15 Amp motor that utilizes advanced soft-start technology for always smooth operation. The motor is also full wave variable speed, and runs at 8,000 – 22,000 RPM. The DW625 runs with a constant speed, even under load, to ensure a fine, quality finish in all your projects, and its one piece motor and shaft spindle ensures perpendicularity and professional accuracy as you work. For always fast and accurate depth settings, the plunge-router also has a rack and pinion depth adjuster, magnified scale, and microfine depth adjustment mechanism. DEWALT’s plunge-router has a spindle lock button that allows for simple one-wrench bit changes and a dust extraction adapter for a cleaner, safer work-space. The tool also has phosphorous bronze bushings that provide a smooth and accurate plunge, and a guide bushing adapter plate that accepts standard guide bushings – perfect for template work. DEWALT’s DW625 plunge router weighs 11.2 lbs and includes a ¼ in and ½ in collet, dust extraction adapter, template guide bushing adapter, and wrench.

Both classes of router offer a different set of features and applications, and each individual tool has its own specifications. Each option, however, offers unique and professional finishes to your woodworking projects.

Gasoline-powered lawn mowers are loud, and emit a great deal of pollution. The solution is the electrical or battery-powered lawn mower. Battery-powered lawn mowers are good for small lawns.

Most lawn mowers are powered by gasoline. Up until recently they have been the easiest mowers to use. It was necessary only to pull the starter cord a few times, or use the electric starter, and then mow to your heart’s content. But gasoline-powered mowers are noisy and they do rather pollute the air with their emissions.

One of the knocks against the electric-powered lawnmower was that it was awkward to use. The mower must be plugged in via a long power cord, and care must be taken not to snarl or run over the power cord.

Now, you’ve got another choice – the battery-operated lawnmower. A battery-operated lawnmower will generally have enough power to allow the operator to mow both the front and back yards on one charge, unless they are extremely large.

It all depends on the battery, though. Some batteries last for thirty minutes between charges, others last up to an hour. The key thing is that they are rechargeable, so that there’s no need to bury them in a garbage dump. Although…even these batteries only last about five years or so – and then must be recycled.

There are several types of batteries: alkaline – which are not used in lawn mowers, lead acid – which are gradually being replaced by nickel cadmium, and lithium batteries – which are not only expensive but also have low storage capacity.

Nickel cadmium batteries
If you are buying a new battery operated lawn mower, make sure you get one powered by a nickel cadmium (Ni-cad) battery. They are simply better than the lead acid – they can be recycled and are environmentally friendly.

Extending battery life
As with any other type of mower, there are times when you should mow your lawn and times when you shouldn’t. You should never try to mow wet grass – it produces a tremendous strain on the battery – or engine – and doesn’t do your grass much good, either. Don’t let your grass grow such that you’re cutting off more than three inches at a time – again, bad for the engine or battery, and bad for the grass itself.

Ni-Cad batteries
Ni-Cad batteries are maintenance free. All you need to do is make sure you do not re-charge the batteries until they are completely discharged. The batteries have a ‘memory’ – if you recharge them when they don’t need to be, they will remember the energy state they were at when they were recharged, and will believe themselves to be run down the next time they reach that state – even though they have plenty of power left. (Okay, there’s a bit of anthropomorphism there, but you get the idea.)

If you’re concerned about the environment – and we all should be – the battery-operated or electrical lawn mowers should be our choice.

robotic mowers Features :

This robotic lawn mower can mow for 3 hours before it need recharge. When the charge goes down in robotic lawn mowers, the mower automated return to work station and charge itself. The normal charge time is 150 minutes-180 minutes.

Multifunction display Lawn Bott’s back-lit display, with two rows of sixteen characters each, makes it easy to view all functions whether you’re programming or merely checking on the mower’s status. You can now also set the language to either English, Spanish, French, German, Italian, or Portuguese. Battery consumption is microprocessor controlled to ensure long battery life-span.

Auto program method- mower determines how long it is necessary to operate to maintain lawn. This is done by sensing blade motor current.

Smart Spiral – When the mower senses long grass it instantly enters spiral mode and mows grass in immediate area in more efficient spiral mode. When long grass is not sensed it returns to random operation to search out more long grass.

Lithium batteries – lower weight for easier traction and handling
