Page 2: Safety Precautions
Warnings The LST XXL is equipped with a reverse gear. Just like a real automobile you must wait for the model to come to a complete stop before shifting between forward and reverse. Failure to do so will cause damage to the transmission. -
Page 3: Break-In Procedure
• Small flat blade and Phillips screwdrivers • Needle-nose pliers • Quality .050-inch, 1/16-inch, 5/64-inch, 3/32-inch, 1.5mm and 2.5mm hex (Allen) drivers Engine Break-In and Adjustments Breaking in your new engine is critical for proper performance. Failure to follow the break-in procedures can cause damage and shortened engine life. During break-in and when running, always use Losi Nitrotane 20% Sport Fuel. Although the carburetor is preadjusted at the factory, you must be familiar with the following adjustments and break-in procedure. If you change fuel or run in dramatically different environments (hot/cold, high/low elevation, etc.) you will probably have to adjust at least the high-speed needle to prevent overheating and maintain proper performance. Never, under any circumstances allow the engine to rev freely with the wheels off the ground. Break-In Procedure 1. T he first three tanks of fuel should be run with the high and low speed needles noticeably “rich” (see explanation below). There should be a slight sluggishness and thick smoke when accelerating with the smoke decreasing as the model gains speed. At speed, there should still be a noticeable trail of smoke from the exhaust pipe. Run the LST XXL on a flat surface in an oval pattern. Ease into the throttle as you accelerate... - Page 4 Base Start-up Settings from the Factory High-Speed Needle—2 turns out from bottom Low-Speed Needle—2 turns out from bottom Engine Tuning After the engine is broken in, you can tune it for optimum performance. When tuning, it is critical that you be cautious of overheating as severe damage and premature wear can occur. You want to make all carburetor adjustments in “one hour” increments.

Page 5: About The Radio
About Glow Plugs The glow plug is like the ignition system in your automobile. The coiled element in the center of the plug glows red hot when connected to a 1.5-volt battery (located in the igniter). This is what ignites the DYN2495 Shown fuel/air mixture when compressed in the cylinder. After the engine fires, the heat generated by the burning fuel keeps the element hot. Common reasons for the engine not starting are the 1.5-volt battery being weak, the glow plug being wet with fuel, or the element burned out. Use a spare glow plug to check the igniter. If the igniter makes the element glow, remove the plug from the engine to check it in the same manner. A wet glow plug means there is excess fuel in the engine. -
Page 6: Maintenance
Maintenance In addition to the service needs pointed out in this guide, you should try to maintain your new LST XXL for proper performance and to prevent wear. If dirt gets in the moving parts it can seriously hinder the performance of the model. Use compressed air, a soft paintbrush and/ or toothbrush to remove dirt and dust. Avoid using solvents, if possible, as this can acutally wash the dirt into bearings and areas not accessible without disassembly, causing additional wear. -
Page 7: Speed Adjustment
Adjusting the Slipper The slipper is a key component of the drivetrain that is designed to help absorb sudden or large impacts that would otherwise stress various drivetrain parts. You should never run the LST XXL with the slipper locked (completely tight). The slipper can also be used as a tuning aid for extremely slick conditions. To adjust the slipper, start by turning the 1/4-inch adjustment nut clockwise (tighten) until it gets tight and the spring is compressed. Do not overtighten as you will strip the nut. Now turn the adjustment nut counterclockwise (loosen) one full turn. This should be a good overall setting. 2-Speed Adjustment Although pre-adjusted at the factory, the two-speed can be adjusted to shift Slipper - 1 turn out at the point that suits you best. Under normal circumstances, it should shift slightly before the engine reaches maximum power. - Page 8 Replacing the 2-Speed Gears First (Low) Gear: After removing the outer gear cover remove the large circlip at the outer face of the gear. Remove and replace the gear being sure to insert the molded pins on the back of the gear with the holes in the aluminum hub. Replace the circlip. Note: Special pliers are made that make removal and installation of the circlip easier. Second (High) Gear: Remove the nut and the thrust washer assembly from the slipper.
- Page 9 Servicing the Differentials The differentials should be serviced periodically. Be sure to clean and inspect all of the gears and replace if severely worn. Always use plenty of high-quality grease (like Losi LOSA3066)on all gears. NOTE: These can also be made into racing type viscous diffs as noted below. Always service one diff at a time and pay close attention to installing the housing with the “TOP” marking up so it can be seen looking down on the chassis. Fig 1. Fig 2. Fig 3. Removing the Differentials • Remove the two screws in the bottom at the extreme end of the chassis (fig1) • R emove the four screws in the bulkhead allowing the bumper/skidplates and pin mounts to be removed (fig 2).

5. Remove the five transmission mounting screws and lift the transmission out. 6. R emove the outdrive and ten 5/64” cap head screws. Remove the transmission case half. 7. Regrease the gears and shafts, inspecting each for wear. 8. Replace any worn or failed gears. 9. W ipe out the inside of the gear case, removing any debris, old grease and foreign matter. 10. Check all ball bearings for free movement cleaning or replacing as necessary. 11. Reinstall gears on the shafts lubing with LOSA3066 or LOSA99203 Losi Assembly Grease. 12. Reassemble the transmission lubricating liberally with LOSA3066 or similar high-grade grease. 13. Make sure the setscrews in the outdrive cups are tightened (a locking compound is highly suggested). 14. I nstall the transmission in the chassis; reset the gear mesh by using a small piece of paper between the pinion and spur gears, applying pressure while retightening the engine.
