WISCONSIN MODE~ W2-880 TJD, THD, TH REPAIR ]~CORP.

FOREWORD Good operation anda planned maintenance program as outlined in this manual are vital in obtaining maximum engine performance andlong engine life. Theinstructions on the following pages have been written with this in mind,to give the operatora better understanding of the various problems which may arise, andthe manner in which these problems can best be solved or avoided. The operator is cautioned againstthe useof anyparts, other than genuine Wis-Con Total Power Corp.parts, for replacement or repair. These parts have been engineered and tested for their particular job, and the useof any other parts may result in unsatisfactory performance and short engine life. Wis-Con Total Power Corp. distributors and dealers, because of their close factory relations, canrender the best and most efficient service. THE LIFE OF YOUR ENGINE DEPENDS ON THE CARE IT RECEIVES. The MODEL, SPECIFICATION and SERIAL NUMBER of your engine must be given when ordering parts. The MODEL and SPECIFICATION number are on the name plate. The SERIAL NUMBER is stamped either on the crankcase or the engine’s identification tag. Copy the MODEL, SPECIFICATION and SERIAL NUMBER in the spaces provided below so that it will be available when ordering parts. MODEL SPECIFICATION SERIAL NUMBER To insure prompt and accurate service, the following informationmust also be given: 1. State EXACTLY the quantity of eachpart andpart number. 2. State definitely whether parts are to be shipped by express, freight or parcel post. 3. State the exactmailing address.

IMPORTANT READTHESE INSTRUCTIONS CAREFULLY All pointsof operation and maintenance have been covered as carefully as possible,but if further information is required, send inqt,~iries to the factoryfor prompt attention. When writing to the factory, ALWAYS GIVE THEMODEL, SPECIFICATION AND SERIAL NUMBER of the enginereferred to. Starting and Operating New Engines Careful breaking-in of a new engine will greatly increase its life and result in troublefree operation. A factory test is not sufficient to establish the polished bearing surfaces, which are so necessary to the proper performance and long life of an engine.These can only be obtained by runninga new engine carefully and under reduced loadsfor a short time. ¯ Be surethe engine is filled to the proper level with a good quality engine oil. ¯ For proper procedures to follow when breaking-in a new engine, see’Testing Rebuilt Engine’. The various bearing surfaces in a new engine have not been glazed, asthey will be with continued operation, and it is in this period of "running in" that specialcaremust be exercised, otherwise the highly desired glaze will neverbe obtained. A new bearing surface that has once been damaged by carelessness will be ruined forever.

IMPORTANT SAFETY NOTICE Proper repair is important to the safe and reliable operation of an engine. This Repair Manual outlines basic recommended procedures, some of whichrequire special tools, devicesor work methods. Improper repair procedures canbe dangerous and could result in injury or death.

Safety Precautions ¯ Never fill fuel tank while engine is running or hot; avoid the possibility of spilled fuel causing a fire. ¯ Always refuel slowly to avoid spillage. ¯ When starting engine, maintain a safe distance from moving parts of equipment. ¯ Do not start engine with clutch engaged. ¯ Do not spin hand crank when starting. Keep crank- ing components clean and free from conditions which might cause the crank jaw to bind and not re- lease properly. Oil periodically to prevent rust. ¯ Never run engine with governor disconnected, or operate at speeds in excess of 3600 R.P.M. load. Do not operate engine in a closed building unless the exhaust is piped outside. This exhaust contains carbon monoxide, a poisonous, odorless and invi- sible gas, which if breathed causes serious illness and possible death. Never make adjustments on machinery while it is connected to the engine, without first removing the ignition cables from the spark plugs. Turning the machinery over by hand during adjusting or cleaning might start the engine and machinery with it, causing serious injury to the operator. ¯ Precaution is the best insurance agvinst accidents. Keep this book handy at all times, fami- liarize yourself with the operating instructions.
