Pruning with ease.

Lightweight Woodzig power pruners, produced by the Oregon Cutting Systems Division of Blount Inc., Portland, Ore., function as miniature chain saws but have the style, operation, and ergonomics of a home appliance.

Impact-modified Makroblend UT-1018 polycarbonate/PET resin from Miles Inc. is used for the tool's housing (which doubles as the handle), battery pack, trigger, and safety button. The resin is highly impact- and chemical-resistant, dimensionally stable, and readily moldable.

The handle/housing units, which have a diameter of about 3 inches, and range in length from 10 to 13 inches, depending on the model, are connected to the tool's 5-inch-long cutting cassette by a bolt in a molded-in brass insert. The cutting chain is driven by a motorized steel shaft protruding from the housing. The weight of the two hand-held models ranges from 3.2 lbs for the 110-volt plug-in AC unit to 3.8 lbs for the 13.2 volt DC battery-operated version. The pole-pruning telescopic models include an AC unit that weighs 6.5 lbs, and a battery-powered DC design weighing 6.8 lbs. The pole pruners include 8-ft-long glass fiber poles, giving the tools an overall length of 10 ft.

The resin is formulated to provide toughness, especially at low temperatures, and excellent resistance to gasoline and other hydrocarbons. Polymers Marketing Communications Dept., Miles Inc., Mobay Rd., Pittsburgh, PA 15205-9741; (412) 777-2000. Circle 169.
