A collection of technical terms which are useful for navigating your way through the jargon jungle of the gardening world.
Primer and Starter Devices which facilitate cold starting of the engine. Specifically they enable the carburettor to be instantly filled with fuel ready for starting.
Anti-vibration system Vibration damping system which completely isolates the handles from the rest of the tool for maximum user comfort, even during prolonged use.
Compression Wave Injection Fuel injection method for two-stroke engines, whereby a compression wave is used to deliver a rich fuel mixture into the engine cylinder.
Safety Control system Safety system on Multimate which stops the engine as soon as the operator tries to detach the implement from the drive unit.
Change Over system System which enables the machine to be switched easily between the collection and mulching functions, by means of a handy lever.
Quick Fit system System which allows quick attachment and removal of the cutting deck and other accessories in just a few minutes, without the need for tools.
Automat System System which stops the blades when the collection bag is full.
Lift Starter Device which automatically cuts off the starter when the accelerator is fully throttled.
Total Stop system System switches off the motor when the flow of water through the wash lance is shut off.
Mulching cut Cutting system which repeatedly chops up grass into fine particles and then scatters it evenly over the turf.
Turning radius Radius or diameter of the arc-shaped path travelled by the front wheels with the steering wheel turned full lock.
Handgrip rotation (180°, 90° clockwise and 90° anticlockwise) System which ensures maximum versatility of use, even close to walls.
Carving bar Particularly useful for tending plants when a precise and deep cut is needed. The carving bar is specially designed for wood carving and sculpting.
Knob Handgrip which enables the machine's cutting height to be altered.
Deck Body of the lawnmower, can be made of plastic (propylene or ABS), steel or aluminium.
Variable speed control System with enables the machine to operate over an infinite range of speeds, making it adaptable to any type of grass.
Voltage and frequency Ratings within which the power supply must operate for the use of electrical appliances.
Cutting width The cutting width depends on the cutting deck of the machine, in relation to the expanse of the area to be cut.
Bag Recipient into which grass clippings are deposited. The width of the bag determines the collection capacity and the amount of time between emptying.
Propulsion Can be push-type, for smaller areas, or self-propelled for larger areas.
Bearing Mechanical device which reduces friction in the wheels. Wheels mounted on bearings ensure consistently smooth running, even over the most uneven terrain.
Bar and chain These two components comprise the cutting apparatus of a chain saw: the toothed cutting chain slides along the guide bar.
Depth gauge On chain saws, this device regulates the maximum cutting depth of the chain.
Inertia-activated chain brake Stops the chain in the event of kickback. Activated manually by means of a lever, or automatically, when the front hand guard is pushed forward due to unexpected kickback.
Chain tensioner Used after every 30 minutes of operation, enables the chain tension to be adjusted by means of a screwdriver, without disassembling any components. The correct tension is achieved when the chain can be raised a couple of millimetres away from the guide bar.
Self-cleaning filter The special design of the air filter and corresponding mount reduces the need for maintenance.
Automatic oil pump with zero flow when idling Actuated by means of the pinion, enables chain lubricant oil to be delivered only when cutting, thereby preventing waste and reducing pollution.
Cylinder The cylinder is the component used to create linear motion; the area in which the combustion process takes place.
Piston The moving component, housed inside the cylinder and connected by means of the gudgeon pin to the connecting rod, which forms a "mobile wall" of the combustion chamber.
Connecting rod Part of the connecting rod-crank mechanism, e.g. the mechanism which enables alternate rectilinear motion to be transformed into continuous rotary motion.
Transmission The set of components which transfer the power generated by the engine or motor to the wheels.
Digital coil Generates high-voltage current, which when it reaches the spark plug creates the spark which triggers combustion.
Oil pump Draws lubricant from the sump and sends it to pressurised components in the engine lubrication circuit.
Air filter Component which protects the engine by preventing dust from entering the cylinders.
Crankshaft A rotating mechanical shaft with a series of cranks which enables the movement of the connecting rods is transmitted to the power take-off.
Catalytic muffler A device installed in the initial section of the exhaust system which drastically reduces the quantity of pollutants (carbon monoxide, hydrocarbons and nitrogen oxides) present in the combustion gases.
Bevel gear A transmission system with helical gears which transfers movement to the cutting assembly, parallel to the ground, with suitable speed reduction.
Drive belt A drive belt is a mechanical transmission component looped over pulleys which is used to provide an elastic but solid link between two rotating shafts.
Rotor A component which rotates inside the stator and which transmits motion to electrical machines.
Lockable differential The differential is a device which enables two wheels to move at different speeds. Locking the differential prevents one of the two drive wheels from spinning in the event that it temporarily loses grip.
Casing Metallic enclosure which protects the engine components.
Handlebars Leverage system which enables the equipment to be kept under control.
Power take-off The power take-off or PTO consists of a connection at the back or front of the machine to which implements are attached.
Grease nipple System which simplifies periodic replenishment of lubricant grease in the gearbox.
Reduction unit Assembly used to transmit rotary motion with a reduction in the number of revolutions.
Fuel tank Container for storing fuel inside the machine.
Starter rope handle Handle connected to the recoil starter rope which is used to start the engine.
Carburettor Mechanical part of internal combustion engines which blends air and fuel for injection into the combustion chamber.
Mixture Mixture of lubricant oil and fuel which is usually used in two-stroke engines. This mixture is important because it lubricates the mechanical components of the engine and provides a source of energy.
Expansion clutch Transmits movement to the cutting implement and also enables it to remain stationary at idling speed without having to stop the engine.
Dipstick The dipstick, present in 4-stroke engines, is immersed in the oil and is used to check the level (MIN and MAX with graduated scale) and quality of the oil.
