General Safety PrecautionsA. Avoid Carbon Monoxide PoisoningAll engine exhaust containscarbon monoxide, a deadly gas.Breathing carbon monoxide cancause headaches, dizziness,drowsiness, nausea, confusionand eventually death.Carbon monoxide is a colorless, odorless, tasteless gaswhich may be present even if you do not see or smell anyengine exhaust. Deadly levels of carbon monoxide cancollect rapidly and you can quickly be overcome andunable to save yourself. Also, deadly levels of carbonmonoxide can linger for hours or days in enclosed orpoorly-ventilated areas. If you experience any symptomsof carbon monoxide poisoning, leave the areaimmediately, get fresh air, and SEEK MEDICALTREATMENT.To prevent serious injury or death from carbon monoxide:• NEVER run engine indoors. Even if you try toventilate engine exhaust with fans or openwindows and doors, carbon monoxide can rapidlyreach dangerous levels.• NEVER run engine in poorly-ventilated or partiallyenclosed areas such as barns, garages,basements, carports, under dwellings, or in pits.• NEVER run engine outdoors where engineexhaust can be drawn into a building throughopenings such as windows and doors.B. Avoid Gasoline FiresGasoline (fuel) vapors are highly flammableand can explode. Fuel vapors can spreadand be ignited by a spark or flame manyfeet away from engine. To prevent injury ordeath from fuel fires, follow theseinstructions:• NEVER store engine with fuel in fueltank inside a building with potential sources ofignition such as hot water and space heaters,clothes dryers, electric motors, etc.• NEVER remove fuel cap or add fuel when engineis running.• NEVER start or operate the engine with fuel fill capremoved.• Allow engine to cool before refueling.• NEVER fill fuel tank indoors. Fill fuel tank outdoorsin a well-ventilated area.• DO NOT smoke while refueling tank.• Use only an approved red GASOLINE containerto store and dispense fuel. Tecumsehrecommends purchasing gasoline in containerswith a capacity of 2.5 gallons or less. Smallcontainers are easier to handle and help eliminatespillage during refueling.• DO NOT pour fuel from engine or siphon fuel bymouth.C. Adult Supervision of Operation,Refueling and MaintenanceNot everyone who is allowed to use an engine is capableof safely and responsibly operating, maintaining and/orfueling it. Tecumseh recommends the following:• An adult should fuel the engine. NEVER allowchildren to refuel an engine.• An adult should perform maintenance on an engine.Only allow children to perform maintenance if anadult has determined they are experienced andcapable of such operation.• An adult should start the engine. Only allow childrento start the engine if an adult has determined theyare experienced and capable of such operation.To avoid unsupervised operation of the engine,especially by children, NEVER leave it unattendedwhen it is running.D. Stay Away from Rotating PartsNEVER operate an engine with an unguarded engineshaft.The equipment manufacturer mayattach a sprocket and chain or pulleyand belt to the engine shaft. If theseparts are not properly guarded, or if youare not sure whether they are properlyguarded, DO NOT use your engine;contact the equipment manufacturer.Hands, feet, hair, jewelry, clothing, etc.can become entangled in rotating parts,leading to serious injury or death. Toavoid serious injury or death, be surethe flywheel guard is in place.iii

Fuel RecommendationsToday’s fuels have a short shelf life and it is recommended you buy no more than a two week supplyat a time.GASOLINETecumseh Power Company strongly recommends the use of fresh, clean, unleaded regular gasoline inall Tecumseh engines. Unleaded gasoline burns cleaner, extends engine life, and promotes good startingby reducing the build-up of combustion chamber deposits. Leaded gasoline, gasohol containing no morethan 10% ethanol, premium gasoline, or unleaded gasoline containing no more than 15% MTBE (MethylTertiary Butyl Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, can be used if unleadedregular gasoline is not available.Reformulated gasoline that is now required in several areas of the United States is also acceptable.NEVER USE gasoline, fuel conditioners, additives or stabilizers containing methanol, gasohol containingmore than 10% ethanol, unleaded regular gasoline containing more than 15% MTBE (Methyl Tertiary ButylEther), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, gasoline additives, or white gas becauseengine/fuel system damage could result.SPECIALTY FUELSFuels being marketed for use on small engines can have a significant effect on starting and engineperformance. Prior to using any specialty fuel, the Reid Vapor Pressure (RVP) must be determined. Fuelswith a rating of less than 50kPa (7psi) should not be used in summer, and fuel with a rating of 85kPa (12psi)should not be used during winter.SHORT TERM STORAGEWARNING NEVER store the engine with fuel in the fuel tank inside a building with potential sourcesof ignition such as hot water and space heaters, clothes dryers, electric motors, etc.If engine fuel stored in the gas tank and/or an approved gas container is to be unused without gasolinestabilizer for more than 15-30 days, prepare it for short term/seasonal storage.Tecumseh recommends using ULTRA-FRESH or Fuel Saver Plus Gasoline Stabilizer plus FuelSystem Cleaner as an acceptable method of minimizing formation of fuel gum deposits during storage.This product is available from your Authorized Tecumseh Servicing Dealer.Always follow mix ratio found on stabilizer container. Failure to do so may result in equipment damage.It is not necessary to drain stabilized gas from carburetor.FUEL TREATMENT1. Add fuel stabilizer according to manufacturer’s instructions.2. Run engine at least 10 minutes after adding stabilizer to allow it to reach carburetor.3. Instead of using a fuel preservative/stabilizer, you can empty the fuel tank as described under"Extended Storage”.8

Fuel Recommendations - continuedEXTENDED STORAGENOTESClean debris from engine before draining fuel from carburetor. If you have prepared your fuel for shortterm storage it is not necessary to drain fuel that contains stabilizer from your carburetor.To avoid severe injury or death, DO NOT pour fuel from engine or siphon fuel by mouth.1. To prevent serious injury from fuel fires, empty fuel tank by running engine until it stops from lackof fuel. DO NOT attempt to pour fuel from engine.2. Run the engine while waiting until the remaining fuel is consumed.NEVER leave the engine unattended when it is running and NEVER run engine in enclosed areas.FUEL ADDITIVESOnly fuel additives such as Tecumseh’s fuel stabilizer Part No. 730245A or liquid varieties can be usedwhen mixed properly. For winter applications, Isopropyl alcohol fuel dryers may be used in the fuel systembut must be mixed at the proper ratio recommended by the manufacturer. NEVER USE METHANOLBASED FUEL DRYERS.9

Tecumseh 4-Cycle Lubrication RequirementsTecumseh recommends the use of a high quality, brand name oil with a minimum classification of SL/SJ.Very few air cooled engines have any type of oil filtration system, making regular oil changes critical toremove impurities from the engine and maximize engine life. Consult the operator's or repair manual forthe oil change interval and viscosity based on equipment operating temperature.Tecumseh Recommended Oil UsageStraight GradeTecumseh Part No.730225A or SAE30W-20 OF-30 OCMulti GradeTecumseh Part No.730226A or SAE5W30 or SAE10WSyntheticTecumseh Part No.730263 or SAE0W30-20 OC0 OF20 OF-10 OC32 OF0 OC40 OF10 OC60 OF80 OF20 OC30 OC100 OF40 OCTECUMSEH4-CYCLE ENGINE OILshown with model names prior to 2004CLASSIFICATIONS: “SL/SJ"DO NOT USE 10W40CAPACITIES:Engine Model ml Oz.All LAV, TVS, LEV, OVRM ................................. 630 21ECV, TNT ........................................................... 630 21V & VH50-70 ...................................................... 810 27TVM 125, 140 ..................................................... 810 27TVM 170-220 ..................................................... 960 32VM70-100, HHM80............................................. 960 32VH100 ................................................................ 1500 50All VLV................................................................ 810 27VSK90-100 ........................................................... 630 21OVM120, OVXL120, 125 ................................... 960 32OHV11-13 without filter ...................................... 960 32OHV11-13 with filter ........................................... 1170 39OHV13.5-17 with filter ........................................ 1800 61OHV13.5-17 without filter ................................... 1650 55TVT691 with filter ............................................... 2150 71TVT691 without filter .......................................... 1950 64H, HSK30-35 ...................................................... 630 21HS, HSSK40-50 ................................................. 630 21H, HH, HSK50-70 ............................................... 570 19OHH/OHSK50-70 ............................................... 630 21HMSK, HM70-100 .............................................. 720 26OHSK80-100 ...................................................... 720 26OHM120, OHSK110*-130 .................................. 840 28HH100,120, OH120-180 .................................... 1560 52*NOTE: Model OHSK110 with a spec. of 221000 and up, have acapacity of 26 oz.

Failure to do so could result in death or serious injury to yourself and/orbystanders.DO NOT attempt any maintenance procedures with the engine running. Doing so could result indeath or serious injury to yourself and/or bystanders.Use care when performing inspection of the drive belt assembly including all vehicle linkage.Failure to do so could result in death or serious injury to yourself and/or bystanders.Hard Shifting Transaxles and Drive BeltsOften hard shifting is blamed on an internal problem in the transaxle.To determine if the problem is transaxle or equipment related make these simple checks.1. Turn the unit off so that all power is removed to the transaxle.2. With the unit off, move the shift lever through the shift gate. Movement of the lever should have only slightresistance. The shifting effort should be equal when the engine is off and when running. If the unit is difficultto shift the problem would be internal and the transaxle would need to be removed and repaired.3. If the unit shifts with ease, check the following areas that would be equipment related. Check to see if the beltis releasing from the pulley on the engine and transmission / transaxle, it may require that the belt guides berepositioned. The distance required from the pulley to the guide is typically 1/16" to 3/16" (1.6 mm - 4.8 mm),always check the O.E.M. specs.1/16" to 3/16"(1.6 mm - 4.8 mm)THIS DIMENSIONVARIES FROM EACHMANUFACTURERFor proper declutching to occur, it is very important thatthe engine belt guide be set at a predetermined clearancewhen engaged (set by the manufacturer) and away fromthe belt with the belt engaged.With clutch disengaged, it is very important that thebelt blossoms away from the engine pulley. Belt muststop turning before transaxle shifting can occur.Improper belt or belt guide clearance will not allow the belt to disengage, causing internal transmissiondamage.20

Basic Gear Drive Troubleshooting - continued4. Check to see if the pulley is damaged and may not be releasing the belt.5. Confirm the correct length and type of belt, as recommended by the manufacturer, is installed.6. Check the brake/clutch pedal to make sure that when the pedal is depressed that the idler pulley is releasingthe belt tension before it applies the brake. If this does not happen the unit will still be under a load and beimpossible to shift.7. The final area to check would be for damaged or binding shift linkage.Hard shifting with the engine off could be caused by:1. Shift linkage out of adjustment.2. Corrosion in the transaxle or transmission.3. Damaged shift keys, gears, or shifter brake shaft.4. Belt guides missing or improperly adjusted (see equipment manufacturer specs).Unit seems to slip:1. Check for proper belt adjustment (consult O.E.M. operator's manual).2. Check for proper clutch/brake adjustment (consult O.E.M. operator's manual).3. Check pulley condition and wheels for sheared or damaged keys.4. Check drive belt condition, if glazed or worn, replace it.5. Possible internal transmission damage. We suggest you contact a local Tecumseh Servicing Dealer.21

1800 / VST TroubleshootingThe information on this page has been provided to help understand the internal operation of the VST. Donot use this information to attempt any internal repairs. Tecumseh's current policy on hydrostatic transaxlesthat have internal failures is to replace the complete unit. This has not changed. However, Tecumsehwould like to provide a failure checklist to assist in making an accurate evaluation of the complete tractorto eliminate any unnecessary replacements. Here is a list of items to check and corrective actions to take.To properly test the unit for power loss.1. Allow the unit to cool before trying the following steps.2. Put the shift lever in a position that is 1/2 of the travel distance from neutral to forward.3. Place the tractor on a 17 o grade.4. Drive the tractor up the grade (without the mower deck engaged). The loss of power experiencedshould be approximately 20%. This is considered normal. If the loss of power is approximately 50%,this would be considered excessive.5. Bring the unit to neutral, shift into forward and note the response. Care should be taken to movethe lever slowly to avoid an abrupt wheel lift.To determine if the problem is with the hydro unit, all external problem possibilities must be eliminated. Hereare some potential problem areas.1. Overheating: Heat can cause a breakdown in the viscosity of the oil which reduces the pressureused to move the motor. Remove any grass, debris, or dirt buildup on the transaxle cover and / orbetween the cooling fins and fan. Buildup of material will reduce the cooling efficiency.2. Belt slippage: A belt that is worn, stretched, or the wrong belt (too large or wide) can cause beltslippage. This condition may have the same loss of power symptom as overheating. Typically, theunit which has a slipping belt will exhibit a pulsating type motion of the mower. This can be verifiedvisually by watching the belt and pulley relationship. If the belt is slipping, the belt will chatter or jumpon the pulley. If the belt is good, a smooth rotation will be seen. Replace the belt and inspect thepulley for damage.3. Leakage: The VST and 1800 Series have two oil reservoirs which can be checked for diagnosticpurposes. The first is the pump and motor expansion bellows. With a small diameter blunt or roundnose probe, check the bellows depth through the center vent hole. Proper depth from the edge ofthat hole is 3-1/4 - 3-1/2 inches (8.25 - 8.9 cm).The second chamber is for the output gears including the differential. FIRST make sure the tractoris level, then remove the drain/fill plug. NOTE: Some units that do not have differential disconnectwill have two plugs. We recommend using only the primary plug. With a small pocket rule insertuntil you touch bottom of case. You can then remove it and check for 1/4 - 3/8 inches (6.5 - 9.5 mm)contact, this is full at its 8 oz. capacity.4. Low ground speed: If the linkage is not synchronized to absolute neutral, or the shift lever is notproperly fastened to the tapered control shaft, full forward travel may not be achieved. This maycause a false reading and be misdiagnosed as a low power condition. This also could be causedby the brake not releasing.To determine absolute neutral, the hole in the tapered control shaft must face straight up and down,at this point make sure the O.E.M. linkage is in neutral. To properly fasten the control lever to theshaft, torque the nut to 25-35 ft. lbs. (34 - 48.3 Nm) of torque with the shaft and the lever in neutral.When attaching the shifter arm to the shaft you must prevent any rotation during torquing. This canbe done by placing a long 5/16" bolt in the hole of the shaft. Hold the bolt until the tapers are lockedand the nut torque is correct.To make sure that the brake is not binding, drive the unit up a slight grade. Position the speed controllever into neutral. The unit should coast backwards. If the unit does not coast back slowly, the brakeis not released from the brake disk. Adjust the brake linkage to release the brake completely whenthe foot pedal is released.5. Hard to shift: Typically hard to shift symptoms are not caused by the hydrostatic unit. The shiftarm should move with relative ease. Approximately 40-50 in. lbs. (4.48 - 5.6 Nm) at the transaxlefor foot pedal units or 150-200 in. lbs. (16.8 -22.4 Nm) for hand operated units. This variesdepending on the type of linkage. Binding may occur in the linkage connections due to rust ormoisture. Lubricating these connections and checking for bent or damaged parts should resolvehard shifting.24
