Odds and endsDoes your company ever install underground, insulated hot or super-chilled water lines? Then you know the process: Dig a trench and put crews of men to work long hours assembling steel pipe with foam insulation filling a steel jacket, which eventually becomes clogged and corroded with age. There is a better way.A company called Ecoflex now has pre-assembled and insulated lengths of single and dual-pipe runs -- as long as 650 ft. -- that can be laid quickly by a minimal crew. Cross-linked polyethylene pipe is available in sizes to 4 in. and all surfaces are smooth as well as non-corrodable, and the insulation doesn''t absorb water.

* Start the washer (Photo 1). If it''s a gas unit, steady it when pulling the starter cord by bracing your foot against a wheel. Let the washer run for a minute to warm up. To avoid damaging the pump: Never run a washer longer than three to five minutes (depending on the model) while the trigger is off* With the washer running and the trigger locked "off," adjust pressure and spray settings, or insert nozzle tips in the spray wand (right photo, p. 30). Now the washer is ready to use.Power cleaning techniques

Joining the established models, the new Triad OHC 653 cc (20 hp) and 725 cc (23 hp) engines offer the same benefits such as improved airflow and temperature distribution and no bore distortion for improved cooling, according to Kohler. These benefits are attributed to Kohler moving the camshaft out of the crankcase and positioning it away from the oil sump and crankcase. A majority of the housing above the crankshaft has been eliminated for a greater cooling area.The 20 hp, TH650 engine, has a compression ratio of 8.8:1 and produces carseatheaters 33.4 lb.ft. of maximum torque at 2600 rpm. The 23 lip, TH720 engine, also has an 8.8:1 compression ratio and produces 39 lb.ft. of torque at 2600 rpm.
