  • Page 17 FIGURE 6: FIGURE 6: It should be noted that the NXT-90 will immediately begin to rotate in the opposite direction to the blades when both of the handles are released. Even with the engine shut down, the drivetrain will have sufficient momentum to spin the handle up to 180 (1/2 turn) before coming to a stop.

  • Page 18: Setting Up The Nxt

    Your Nexus NXT-90 comes fully assembled with the folding handle and engine already installed. Nexus equipment is shipped without engine oil or gasoline, so fill these fluids per your engine’s instruction manual before proceeding. When starting an engine for the first time, or after a long period of storage, several pulls may be required before the engine runs.
  • Page 19 ALWAYS unfold the handle and lock in the open position before starting the engine. Failure to do this may result in equipment damage or personal injury. To completely unfold the handle: 1. Grab the lock arm at the hook and push backward, toward the engine, until the latch releases the grab bar (see Figure 8).

  • Page 22: Trowel Technique

    A rough floor will damage your trowel blades and create excessive vibration. Unfold the handle, start the engine and learn the feel and control of your Nexus Power Trowel, starting at low throttle and working up to full throttle.

  • Page 23: Trowelling

    TROWE TROWE TROWE TROWEL L L L L L L L ING Trowelling the concrete surface eliminates large aggretates near the surface, levels bumps and depressions, and consolidates the surface to make it stronger. The surface must first be sufficiently cured to support the weight of the trowel. The surface should first be leveled using a float or vibratory screed.

  • Page 25: Power Trowel Blades

    FIGURE 1 To reverse a blade, follow these steps: 1. Raise the NXT-90 above the floor by putting blocks under the safety ring or by suspending it by the hoist hook on the folded handle. Work away from the wet concrete or any grates where small parts can be lost.

  • Page 26: Float Blades

    FLOAT BLADES FLOAT BLADES Clip-on float blades are an optional addition to your NXT-90, allowing you to begin the trowelling operation much sooner after the concrete pour than the standard finishing blades. The increased surface area of the float blades allows your NXT-90 to “float” on wetter concrete than the finishing blades will permit.

  • Page 27: Float Pans

    “Panning” is the earliest step that can be performed on wet concrete. The optional float pan allows the NXT-90 to begin working on concrete at the earliest possible time after the pour, and is the most effective tool for floating the concrete. The float pan fits to the existing finishing blades with minimal effort.

  • Page 28: Blade Pitch

    BLADE PITCH BLADE PITCH BLADE PITCH BLADE PITCH The blade pitch is controlled by the knob directly behind the engine. The blades are pitched up as the concrete cures in order to place more direct pressure on the surface being trowelled. To raise the blade pitch turn the pitch knob clockwise. If the pitch is initially at the lowest setting, several full turns will be required before the blades start to raise.

  • Page 29: Storage And Service

    The most important daily activity is to keep the equipment clean and prevent the build-up of dried concrete. The NXT-90 can be cleaned with spray from a hose or pressure washer. Remove all concrete residue, concentrating on moving parts such as the spider assembly, pitch assembly, and drivetrain.

    ROUTINE SERVICE INTERVALS ROUTINE SERVICE INTERVALS ROUTINE SERVICE INTERVALS Due to the nature and environment of use, Nexus Power Trowels could be exposed to severe operating conditions. Some general maintenance guidelines will extend the useful life of your trowel. • The initial service for your Power Trowel should be performed after 25 hours of use, at which time your mechanic (or authorized repair shop) should complete all of the recommended checks in the schedule on Page 31.

  • Page 33: Trowel Arm Adjustment

    TROWEL ARM ADJUSTMENT TROWEL ARM ADJUSTMENT If your NXT-90 Power Trowel is experiencing excessive wobble while in use (i.e. the entire machine is rocking at the same rate that the blades are turning) you may have a bent or out of alignment trowel arm. Inspect the trowel arms for a distinct bend. If one or more arms are in fact bent they must be replaced.
