Pull the lever straight back and slide it up or down to engage the notched height settings. The handlebar height is adjustable to three different settings (see Figure 3-6). As a general rule, adjust the handlebars so they are at waist level when the tines are 3"-4" into the soil. This stake is located at the rear of the The highest notch (lever all the way down) raises the tines approximately 11/2" off the ground. This "travel" setting allows the tiller to be moved without the tines digging into the ground. Also use this setting when starting the engine. Move the lever upward to increase the tilling depth. The lowest notch allows a tilling depth of approximately 6"-8", depending on soil conditions. To Adjustthe Handlebars: 1. Stop the engine, disconnect the spark plug wire from the spark plug and allow the engine to cool. 2. Removethe screws, Iockwashers and nuts, reposition the handlebars, and reinstall the hardware. For best results, begin tilling at the deepest depth possible without causing the tiller to bog down. Increasethe tilling depth from one pass over the soil to the next. Travel Position transmission, under the tine hood (see H, Figure 3-7). Its purpose is to automatically help prevent the counter-rotating tines from letting the tiller back up in the direction of the operator if the tiller wheels had been inadvertently left in the FREEWHEELposition. In this situation, the Anti-Reverse Stake will be forced down into the ground, lifting the tines upward out of the soil and helping prevent backward motion of the tiller. TheAnti-ReverseStake requires no adjustment, but should be inspected before eachtiller useto verify that it swivels freely. Remove any clogged materials (dirt, roots, rocks, etc.) that prevent the Anti-Reverse Stake from swinging freely. L_ jG Shallow Deep _ Settings Figure3-6: Handlebar height adjustment.

Do not attemptto engagetines or wheels until you have read all the operatinginstructionsin this Section. Alsoreview the salety rules in Section1: "Safety" and the tiller and engine controlsinlormation in Section 3: "Features and Controls." 6. Put ignition switch and/or throttle control lever on engine in "ON," "RUN," "FAST"or "START" position as instructed in the separate Engine Owner's Manual. CAUTION To help prevent serious personal injury or damage to equipment: 7. Choke or prime engine as instructed in the separate Engine Owner's Manual. 8. Place one hand on the fuel tank to stabilize the unit when you pull the starter handle. Usethe recoil starter rope to start the engine as instructed in the separate Engine Owner's Manual. When engine starts, gradually move choke lever (on engines so equipped) to "NO CHOKE," "CHOKEOFF"or "RUN" position. • Before starting engine, put both wheels in the WHEEL WARNING DRIVE position. Never have the wheels in the FREEWHEEL position when the engine is running. When the wheels are in FREEWHEEL, they do not hold back the tiller and the Hot surfaces can cause severe burns. Do not touch muffler or adjacent areas. 9. Usethe "FAST"throttle speed setting when tilling. • Before starting engine, put Forward Clutch Bail (all Models) and Reverse Clutch Control in neutral (disengaged) positionsby releasing levers. • Avoid engine muffler and nearby areas. Temperatures in these areas may exceed 150OF. 1. Completethe "Pre-Start Checklist" on the previous page. 2. Put the wheels in the WHEELDRIVE position (see "Wheel Drive Pins" in Section 3). 3. Put the Depth Regulator Lever in the "travel" position (lever all the way down) so that the tines are clear of the ground. 4. Releaseall controls on the tiller. 5. If engine is equipped with a fuel valve, 1t'urn4valve to open position as instructed up). 1. Follow the "Pre-Start Checklist" on the previous page. Be sure that the wheels are in the WHEELDRIVEposition. 2. Put the Depth Regulator Lever in the "travel" position (lever all the way down) so that the tines are clear of the ground. Use this position when practicing with your tiller or when moving to or from the garden. When you are readyto begin tilling, you must move the Depth Regulator Lever to the desired depth setting (see "Tilling Tips & Techniques"). Checkthat the Anti-Reverse Stake swivels freely back and forth. Removeany clogged material on or around the stake. WARNING tines could propel the tiller rapidly backward. • Never run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and deadly gas. This creates an "uppercut" tine action which digs deeply, uprooting soil and weeds. Don't overload the engine, but dig as deeply as possible on each pass. On later passes,the wheels may tend to spin in the soft dirt. Help them along by lifting up slightly on the handlebar (palm facing Keep away from rotating tines. Rotating tines will cause injury. Stoppingthe Engineand Tiller 1. To stop the wheels and tines, release the Forward Clutch Bail or the Reverse Clutch Control -- whichever control is in use. 2. To stop the engine, put the throttle control lever on engine in "OFF"or "STOP" position. OPERATINGTHE TILLER The following pages provide guidelines to using your tiller effectively and safely in various gardening applications. Be sure to read "Tilling Tips & Techniques" in this Section beforeyou actually put the tines into the soil. This is a CRT(counter-rotating tine) tiller. As the wheels pull forward, the tines rotate backward. Figure 4-2: Use one hand to guide tiller when movingforward. 3. Start the engine and allow it to warm up. When warm, put throttle control in fast speedsetting. 4. Forforward motion of wheels and power to the tines: (a) Pull the Forward Clutch Bail up and hold it againstthe handlebar. Release the bail to stop forward motion of the wheels and power to the tines. (b) As the tiller moves forward, relaxand letthe wheels pull the unit along while the tines dig. Walk behind and a little to one side of the tiller. Use a light but secure grip with one hand on the handlebars, keeping your arm loose. See Figure 4-2. Section4: Operation WARNING WARNING Do not push down on the handlebars to try to make the tiller till more deeply. This prevents the wheels from holding the tiller back and can allow the tines to rapidly propel the tiller backward toward the operator, which could result in loss of control, property damage, or personal injury. Let the tiller move at its own paceand do not push down on the handlebarsto try to dig deeper- this takes weight off the wheels, cuts traction, and causesthe tines to try and propel the tiller. Before tilling, contact your telephone or utilities company and inquire if underground equipment or lines are used in your area. Their representative will be glad to answer your questions and tell you if any of their equipment or lines are buried underground on your property. Figure 4-3: Raise tines off groundandlook behind whenmovingin reverse. Turning the Tiller Around 5. For reverse motion of the wheels and tines: (a) Look behind and exercise caution when operating in reverse. Do not till while in reverse. (b) Stop all forward motion before reversing. Lift the handlebars with one hand until the tines are off the ground and then pull the Reverse Clutch Control knob out to engage reverse motion (see Figure4-3). To stop reverse motion, let go of the ReverseClutch Control knob. 6. To Turn the Tiller Around: (a) Practice turning the tiller in a level, open area. Be very careful to keep your feet and legs away from the tines. (b) To make a turn, lift the handlebars until the engine and tines are balancedover the wheels (Figure 4-4). The tines must be out of the ground while turning the tiller. (c) With the tiller balanced, push sideways on the handlebar to move the tiller in the direction of the turn (Figure 4-5). After completing the turn, slowly lower the tines into the soil to resume tilling. Figure 4-4: Tobegin turn, lift handlebars until engine and tines are balanced over wheels. Besure tines are out of ground. Figure 4-5: Withtiller balanced over wheels (and tines out of the ground),push handlebars sidewaysto turn tiller. Stoppingthe Tiller and Engine 1. To stop the wheels and tines, release the Forward Clutch Bail or the Reverse Clutch Control- whichever is engaged. 2. To stop the engine, move the throttle control lever on engine to "OFF"or "STOP" position. 15 Section4: Operation Tilling Tips& Techniques Let the tiller dothe work Avoidtilling soggy,wet soil * While tilling, relax and let the wheels pull the tiller along while the tines do the digging. Walk on the side that is not yet finished (to avoid making footprints in the freshly tilled soil) and lightly, but securely grip the handlebar with just one hand. See Figure 4-2. Tilling wet soil often results in large, hard clumps of soil that can interfere with planting. If time permits, wait a day or two after heavy rains to allow the soil to dry before tilling. Test soil by squeezing it into a ball. If it compresses too easily, it is too wet to till. oAvoid the temptation to push down on the handlebars in an attempt to force the tiller to dig deeper. Doing so takes the weight off the powered wheels, causing them to losetraction. Without the wheels helping to hold the tiller back,the tines will attempt to propel the tiller backward toward the operator- often causing the tiller to skip rapidly across the ground. Tilling depths • When preparing the soil, till a fresh path on each pass rather than overlapping passes. This gives the wheels maximum traction on undisturbed soil. See Figure4-6. Dig as deeply as possible on each pass without overloading the engine. Later passescan be overlapped. (Watering the garden area a few days prior to tilling will make tilling easier, as will letting the newly worked soil set for a day or two before making a final, deep tilling pass.) • When cultivating (breaking up the surface soil around plants to help destroyweeds), adjust the tines to dig only 1-1/2" to 2" deep. Using shallow tilling depths helpsprevent injuryto plantswhose roots often grow closeto the surface. If needed,lift up on the handlebarsslightly to prevent the tines from digging too deeply. Cultivatingon a regular basis not only eliminates weeds,it also loosensand aeratesthe soil for better moistureabsorptionand faster plantgrowth. Avoidmakingfootprints Whenever possible, walk on the untilled side of the unit to avoid making footprints in your freshly tilled or cultivated soil. Footprints cause soil compaction that can hamper root penetrationand contribute to soil erosion. They can also "plant" unwanted weed seeds back into the freshly tilled ground. Choosingcorrectwheel and tine speeds In very hard ground it may take three or four overlapping passesto thoroughly pulverize the soil. (See Figure 4-8.) • If the garden size will not permit lengthwise and then crosswise tilling, then overlap the first passesby onehalf a tiller width, followed by successive passesat one-quarter width (see Figure4-8). • With planning, you can allow enough room between rows to cultivate (see Figure4-9). Leaveroom for the hood width, plus enough extra room for future plant growth. Figure4-6 With experience,you will find the "just right" tilling depth and tilling speed combination that is best for your garden. Set the engine throttle lever at a high enough speed to give the engine adequate power and yet allow it to operate without overloading it. Fastest engine speeds may be desirable when making final passesthrough the seedbed or when cultivating. Selection of the correct engine speed, in relation to the tilling depth, will ensure a sufficient power level to do the job without causing the engine to labor. Figure 4- 7 Suggestedtilling patterns • When preparing a seedbed, go over the same path twice in the first row, then make individual passes right next to each other (see Figure4-6). When finished in one direction, make second passes at a right angle as shown in Figure 4-7. Figure4-8 % Figure 4-9 16 Section4: Operation Tilling Tips & Techniques Clearing the tines Tilling on slopes Dry grass, stringy stalks or tough vines may becometangled in the tines. Follow these procedures to help avoid tangling and to clean the tines, if necessary. If you must garden on a moderate slope, pleasefollow two very important guidelines: • To reducetangling, set the depth regulator to maximum depth. • While tilling, try swaying the handlebars from side to side (about 6" to 12"). This "fishtailing" action often clears the tines of debris. • If tangling occurs, lift the tines out of the soil and run the tiller in reverse for a few feet. This may unwind a good deal of debris. • It may be necessaryto remove the debris by hand (a pocket knife will help you to cut away the material). WARNING Before clearing the tines by hand, stop the engine, allow all moving parts to stop and disconnect the spark plug wire. Failure to follow this warning could result in personal injury. 1. Till only on moderate slopes, never on steep ground where footing is difficult (review safety rules in the "Safety" section of this manual). B. Tilling acrossslopeswithout usingterraces: If previously described tilling methods aren't practical for you, then you can till laterally across a slope. However, we don't really recommend this method as it can create unsure footing and invites soil erosion. 2. We recommend tilling up and down slopes rather than terracing. Tilling vertically on a slope allows maximum planting area and also leaves room for cultivating. IMPORTANT:When tilling on slopes, be sure the correct oil level is maintained in the engine (check every one-half hour of operation). The inclineof the slope will cause the oil to slant away from its normal level and this can starve engine parts of required lubrication. Keepthe engine oil level at the full point at all times! A. Tilling up and downslopes: • To keepsoil erosion to a minimum, be sure to add enough organic matter to the soil so that it has good moistureholding texture and try to avoid leaving footprints or wheel marks. • When tilling vertically, try to make the first pass uphill as the tiller digs more deeply going uphill than it does downhill. In soft soil or weeds, you may haveto lift handlebars slightly while going uphill. 17 Section4: Operation LOADINGAND UNLOADINGTHE TILLER WARNING Loading and unloading the tiller into or from a vehicle is potentially hazardous. We don't recommend doing so unless absolutely necessary, as this could result in personal injury or property damage. However, if you must load or unload the tiller, follow the guidelines given next. • Before loading or unloading, stop the engine, wait for all parts to stop moving, disconnect the spark plug wire and let the engine and muffler cool. • The tiller is too heavy and bulky to lift safely by one person. Two or more people should share the load. 18 • Use sturdy ramps and manually (engine shut off) roll the tiller into and out of the vehicle. Two or more people are needed to do this. • Ramps must be strong enough to support the combined weight of the tiller and any handlers. The ramps should provide good traction to prevent slipping; they should haveside rails to guide the tiller along the ramps; and they should havea locking device to secure them to the vehicle. • The handlers should wear sturdy footwear that will help to prevent slipping. • Position the loading vehicle so that the ramp angle is as flat as possible (the less incline to the ramp, the better). Turn the vehicle's engine off and apply its parking brake. ° When going up ramps, stand in the normal operating position and push the tiller ahead of you. Have a person at each side to turn the wheels. When going down ramps, walk backward with the tiller following you. Keepalert for any obstacles behind you. Position a person at eachwheel to control the speed of the tiller. Never go down ramps tiller-first, as the tiller could tip forward. Use wooden blocks to place on the downhill side of the wheels if you need to stop the tiller from rolling down the ramp. Also, use the blocks to temporarily keepthe tiller in place on the ramps (if necessary),and to chock the wheels in placeafter the tiller is in the vehicle. Whenthe tiller is in the vehicle, prevent it from rolling by chocking the wheels with blocks and securely tie the tiller down. Maintenance WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage.

Failure to follow these instructions can result in serious personal injury or propertydamage. TILLERLUBRICATION CHECKFOR OIL LEAKS TRANSMISSIONGEAROIL SERVICE Proper lubrication of the tiller is an essential part of maintenance. After every 10 operating hours, oil or grease the lubrication points shown in Figures 5-1 and 5-1A and described below. Before each use, check your tiller for signs of an oil leak- usually a dirty, oily accumulation either on the unit or on the Checkthe transmission gear oil level after every 30 hours of operation or whenever you notice any oil leak. Operating the tiller when the transmission is low on oil can result in severe damage. Use a good quality lubricating oil (#30 weight engine oil is suitable) and a quality general purpose grease (with a metal lubricant, if available). ,, Removewheels, clean wheel shaft (A, Fig. 5-1) and apply thin coating of grease to the shaft. ,, Greaseback, front and sides of depth regulator lever (B, Fig. 5-1). ,, Removetines, clean tine shafts (C, Fig. 5-1). Inspect for rust, rough spots or burrs (look around holes). Fileor sand smooth, coat ends of shaft with grease. ,, Oil the threads on the handlebar height adjustment screws and the handlebar attaching screws (D, Fig. 5-1). • Shifting Mechanism. Lightly oil pivot pointsfor smooth operation(E,Fig.5-1A). floor where it has been parked. A little seepagearound a cover or oil seal is usually not a cause for alarm. However, if the oil drips overnight then immediate attention is neededas ignoring a leak can result in severe transmission damage. If a cover is leaking, try tightening any loose screws. If the screws are tight, a new gasket or oil seal may be required. If the leak is from around a shaft and oil seal, the oil seal probably needsto be replaced. Seeyour authorized dealer or contact the factory for service or advice. IMPORTANT:Never operate the tiller if the transmission is low on oil. Checkthe oil level after every 30 hours of operation and whenever there is any oil leakage. Figure5-1 Figure5-1A 2O 1. Checkthe gear oil levelwhen the transmission is cool. Gear oil will expand in warm operating temperatures and this expansion will provide an incorrect oil level reading. 2. With the tiller on levelground, adjust the Depth Regulator Lever up or down to the notch that makesthe tiller level.. 3. Removethe oil fill plug (A, Fig. 5-2) from the transmission housing and look into the oil fill hole. You will seethe main drive shaft on one side of the hole. CHECKHARDWARE 4. The gear oil level is correct if the gear oil is approximately half way up the side of the drive shaft. Checkfor loose or missing hardware after every 10 operating hours. Tighten or replace hardware before using the tiller. Be sure to check the screws underneath the tiller hood (lift the hood flap) that secure the transmission cover and the depth regulator leverto the transmission. 5. If the gear oil level is low, add gear oil as described next. If the gear oil level is okay, securely replacethe oil fill plug. IMPORTANT:Do not operatethe tiller if the gear oil level is low. Doing so will result in severe damageto the transmission components. CHECKTIREPRESSURE (on A A. To Checkthe Transmission Gear Oil Level: machines equipped with pneumatic tires) Checkthe air pressure in both tires. Deflateor inflate both tires evenly from 15-to-20 PSI (pounds per square inch). Be sure that both tires havethe same air pressure or the unit will tend to pull to one side. NOTE:Your tiller may not be equipped with pneumatic tires, eliminating the need for air pressure checks. 6. If adding only a few ounces of gear oil, useAPI rated GL-4 or GL-5 transmission gear oil having a viscosity of SAE 140, SAE85W-140 or SAE 80W-90. If refilling an empty transmission, use only GL-4 transmission gear oil having a viscosity of SAE 85W-140 or SAE 140. NOTE:Do not use automatic transmission fluid or engine oil in the transmission. 7. While checking frequently to avoid overfilling, slowly add gear oil into the oil fill hole until it reaches the halfway point on the drive shaft. 8. Securely replacethe oil fill plug. Section5: Maintenance WARNING Before inspecting, cleaning or servicingthe unit, shut off engine, wait for all parts to come to a completestop, disconnectspark plug wire and move wire away from spark plug. Failure to follow these instructions can result in serious personal injury or propertydamage. B. To Drain the TransmissionGear Oil: reducedeffectiveness in general, and specifically when chopping up and turning under organic matter. DANGER Gasoline is highly flammable and its vapors explosive. Follow these safety practices to prevent injury or property damage from fire or explosion. ,, Allow the engine and muffler to cool before draining the tiller's gasoline tank. B. Removingand Installing Tine Assemblies 1. Use a 9/16" socket, 6" extension, a ratchet, and a 9/16" box end wrench to loosen the nut (A, Figure 5-3) and screw (B) that secure the tine holder to the tine shaft. ,, Do not allow open flames, sparks, matches or smoking in the area. Figure5-2: Removeoil fi// plug(A)tocheck gearoil/eve/and toaddgearoil. Remove fourcoverscrews(B) todraingearoil. ,, Wipe away spills and push tiller away from spilled fuel. TINES ,, Use only an approved fuel container and store it safely out of the reach of children. ,, Do not store gasoline where its vapors could reach an open flame or spark, or where ignition sources are present (such as hot water and space heaters, furnaces, clothes dryers, stoves, electric motors, etc.) The transmission gear oil does not need to be changed unless it has been contaminatedwith dirt, sand or metal particles. 1. Drain gasoline from the fuel tank or run the engine until the fuel tank is empty. See "DANGER"statement above. 2. Drain the oil from the engine. 3. Removethe four screws (B, Figure5-2) and washersfrom the transmission cover and remove the cover and gasket. 4. Removethe left-side wheel. 5. Tilt the left-side wheel shaft into a drain pan and allow the gear oil to drain through the top of the transmission. 6. After draining oil, reinstall the wheel, install a new gasket (do not reuse old gasket) and screw on transmission cover. 7. Refill transmission using GL-4 gear oil (SAE85W-140 or SAE 140). 8. Refill the engine with motor oil and replenishthe fuel tank with gasoline. The tines wear with use and they should be inspected at the beginning of each tilling season and after every 30 operating hours. The tines can be replaced individually or as a complete set. Refer to the Parts List Section of this manual for tine identification information. WARNING This is a CRT (counter-rotating tine) tiller and its tines must be mounted in the direction shown in Figure 5-3. If mounted with curves in the opposite direction, tiller will dig poorly and be more likely to run backward. Failure to comply could result in personal injury or property damage. NOTE:You must first remove the tiller hood before removing either a single tine holder or individual tines. Removethe two screws at the front of the hood and the two screws at the rear of the hood and lift off the hood. Be sure to replace the hood securely after changing a tine or tine holders. A. Tine Inspection: With use, the tines will become shorter, narrower and pointed. Badly worn tines will result in a loss of tilling depth and 2. Use a rubber mallet to tap the tine holder loose. Slide tine assembly off. 3. RepeatSteps 1 and 2 aboveto remove the other tine assembly. 4. Installing the tine assembly is simply the reverse of its removal. First be sure to remove any rust, unevenspots or burrs from the tine shaft using fine sandpaper. Then greasethe tine shaft before reinstalling the tine assemblies. Be sure all the cutting edgesface so they will enter the soil first when the tiller is moving forward- this meansthe cutting edge on the top of each tine faces towardthe operator position. Tighten hardware. C. Removingand Installing IndividualTines 1. Use two 9/16" box end wrenchesto remove the two screws (C, Figure 5-3) and nuts (D) that secure the tine to its tine holder. NOTE:If the nuts are rusted, apply penetrating oil, then loosen the hardware. 2. When installing individual tines, do so in the reverse order from which they were removed. The two sets of inboard tines are installed so one set faces toward the transmission and the other faces away from it. The single outboardtine set faces toward the transmission housing. Also be sure the cutting edge at the top of each fine faces toward the operator position. (See Figure 5-3.) 21 Section5: Maintenance WARNING Before inspecting, cleaning or servicing the unit, shut off engine, wait for all parts to come to a completestop, disconnectspark plug wire and move wire away from spark plug.

ForwardBelt Replacement Information 1. Be sure that the engine is stopped and the spark plug wire is disconnected and moved away from the spark plug. If the drive belt needsto be replaced, see your local authorized dealer or phone the factory as instructed on Page 2. Refer to the Parts List in the back of this manual for correct components Use only OEM (Original Equipment Manufacturer) freplacement belts. A substitute belt may not perform satisfactorily. The procedure requires average mechanicalability and commonly availabletools. FORWARDCLUTCH BAILADJUSTMENT If the Forward Clutch Bail does not function properly, first check that the forward drive belt is adjusted properly (see "Checking and Adjusting Forward Drive Belt Tension"). If this fails to correct the problem, contact the factory technical service department or your authorized dealer for service advice. CHECKINGAND ADJUSTING REVERSEDRIVE BELTTENSION Maintaining correct tension on the reverse drive belt is important to good performance and long belt life. A loose belt will slip on the engine and transmission pulleys and cause the tines and wheels to slow down - or stop completely - even though the engine is running at full speed. A loose belt can also result in premature belt wear. If there is no reverse action when the ReverseClutch Control knob is pulled out, then the belt tension is too loose. When checking belt tension, also check the belt for cracks, cuts or frayed edges and replace it as soon as possible. To CheckReverse Belt Tension: 2. Removethe screw in the plastic belt cover and slide the cover (which is attachedto the forward clutch cable) out of the way. 3. Havean assistant pull the Reverse Clutch Control knob all the way out and hold it in that position. Measure the length of the cable wire between the end of the threaded cable adjuster (A, Figure 5-5) and the end of the Z-fitting (B) to which the cable wire is attached. Figure 5-5: Measure cable wire length to checkfor correctreverse belt tension. 4. The belt tension is ideal if the cable wire length measures between 1/8" to 1/4". If the length is less than 1/8" (and if there is no reverse action when the tiller is running), then make the following adjustments. NOTE:If the length is more than 1/4", no adjustment is needed,as long as the reverse action functions properly. 5. Releasethe ReverseClutch Control knob. Unthreadthe inner jam nut (C, Figure5-6) one to two turns and pull the threaded cable adjuster (A, Figure5-6) to the left until the inner jam nut rests against the bracket. 6.

Failure to follow these instructions can result in serious personal injury or propertydamage. ENGINEOIL SERVICE AIR CLEANERSERVICE Checkthe engine oil level before starting the engine each day and check it after each 5 hours of continuous operation. Running the engine when it is low on oil will quickly ruin the engine. The engine air cleanerfilters dirt and dust out of the air before it enters the carbure- It is recommended that you changethe motor oil after every 10 hours of operation and evensooner when operating in extremely dirty or dusty conditions. Refer to the separate Engine Owner's Manualfor detailed service instructions. A. To Checkthe Engine0il Level: 1. Move the tiller to a level area and shut off the engine. 2. Levelthe engine by adjusting the Depth Regulator Lever. The tines must be in contact with the ground. Move the AntiReverseStake back if necessary. 3. Cleanthe area around the oil dipstick or oil fill tube to prevent dirt from falling into the crankcase. 4. On engines with an oil fill tube, remove the filler cap, add oil (if required) until it reaches the top of the tube and reinstall the filler cap. 5. On engines with a dipstick, remove it, wipe it clean, and reinstall it finger-tight. Removethe dipstick and check the reading. Add oil (if required) to bring the levelto the FULL mark. Do not overfill. tor. Operating the engine with a dirty, clogged air filter can cause poor performance and damageto the engine. Never operatethe engine without the air cleaner installed.
