Introduction Thank you for choosing the Losi Raminator Monster Vehicle. This is a highly developed off-road model that features a sophisticated computer-based radio system and does require some mechanical experience and direct adult supervision. This guide contains the basic instructions and drawings for operating and maintaining your new Raminator. Please take the time to read through it completely before running the model.
Required Equipment You will need the following items to operate your new Raminator. 4 AA alkaline batteries for the transmitter Losi™ Nitrotane™ 20% Sport Fuel. (LOSF0020 or LOSF0120) This is the only fuel that supports the engine warranty. Fuel bottle (LOSB5201) 6V Receiver Pack (LOSB9949 or similar) Tools You Will Find Handy In addition to the tools included with the Raminator, you will find the following both useful and in some cases necessary.
1H our Base Start-up Settings from the Factory High Speed Needle—23/4 turns out from bottom Low Speed Needle—3 turns out from bottom 2H 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.
Hi Speed Adjustment After initial acceleration the engine should pull at a steady rate while maintaining a two-stroke whine and a noticeable trail of smoke. If the engine labors and is sluggish with heavy smoke, the mixture is too rich and needs to be leaned by turning the high speed needle clockwise in one hour increments until it runs smoothly. If the engine isn’t smoking or starts to die after acceleration, it is too lean and you must richen the mixture by turning the needle counterclockwise.
About the Radio The Losi DSM radio installed in the Raminator is a state of the art system featuring the latest technology that requires no crystals. This system includes all the features you may find useful. Be sure to read through the Radio operation instructions on what and how to use these features. The following is a simple guide to items and functions commonly referred to. 1. 2. 3. 4. 5. 6. 7. Steering Wheel - Controls the trucks direction (left/right).
Steps to Re-Bind 1. Ensure that the transmitter and vehicle are both turned off. 2. Using the supplied Bind plug (which looks like a standard receiver plug with a wire loop installed) insert the Bind plug into the receiver slot labeled “BIND”. Looking down on the receiver this slot would be below the LED and is the farthest from the LED, or nearest to the corner of the receiver. Note: You do not need to remove any of the other plugs to re-bind. 3. With the Bind plug installed, turn on the vehicle.
Radio Operation It is important that you familiarize yourself with the radio system, as this is your direct link to the model. • Never run your model with low receiver or transmitter batteries. • Never leave the power on or the batteries will not last long. • Always turn the transmitter ON before turning the model ON. • When finished running, always turn the model OFF before the transmitter.
2-Speed Adjustment When new and during engine break-in, the two speed will not shift. Only after the engine has been broken in and the needle valve adjusted, if necessary, will it start shifting. You may need to adjust the shift point after a while as the shoes wear in. Although pre-adjusted at the factory, the two speed can be adjusted to shift at the point that suits you best. Under normal circumstances, it should shift slightly before the engine reaches maximum power.
Replacing the 2-Speed Gears Be sure to replace the one-way bearing in the same direction as removed. Replacing the Clutch Bell Use a 3/32” wrench (provided) to remove the retaining screw (turn counterclockwise) while firmly holding the flywheel with a pair of pliers. Remove the screw, washers and clutch bell, being careful not to lose any shims that may be used. Remove the ball bearings and brush any loose dirt away from the bearing faces.
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 or LOSA99203) 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.
Servicing the Transmission The Transmission should also be cleaned and serviced periodically. All gears and shafts should be closely inspected for wear and replaced if necessary. Always use a high quality grease or lubricant to prevent premature wear and/or failure. Removing the Transmission 1. Remove the gear cover. 2. Remove the throttle linkage from the carburetor and the brake linkage from the servo arm. 3. Loosen the four motor mount screws (bottom of the chassis) and slide the motor back. 4.
Rebuilding/Refilling the Shocks Tools Needed Step 1. After removing the shock, push up on the lower spring cup and snap it off of the shaft. Remove the spring. Step 2. Turn the shock upside down and, using the included shock tool, remove the black shock cartridge/shaft assembly from the shock body by turning it counterclockwise. NOTE: If you only wish to change or fill the shock fluid, skip to step 6. B2900 A6234 B2876 B2815 Step3. Remove the 1/4" nut by turning it counterclockwise.
