Operation Power Trowels ST92 Electric Motor

Before starting

  • Lift the wheels.
  • Open the extension handle and adjust to a comfortable working height.

Starting the motor :

  • Place trowel on the concrete.
  • Turn the motor switch to the 1 or 2 position
  • Check that the emergency stop button is in the out position. If not rotate it clockwise to recease.
  • Press the yellow button and then press the Dead Man Control Handle.
  • If the motor rotates and the trowel blades do not rotate the motor is rotating in the wrong direction.
  • Release the Dead Man Control Handle.
  • Remove the plug from the control box on the machine and rotate the 2 pins inside the plug.using a screw driver press the phase change pins in and then rotate.
  • Replace the cable and check the rotation that the blades rotate.

Operating the trowel

NOTE :Always operate the trowel using the Dead Man Control Handle.

Assembly of the float disc

  • Place the trowel on to the float disc.
  • Rotate the blades so that the blades move underneath the 4 L shaped brackets.
  • Rotate the blade adjustment knob so that the blades rise.
  • Ensure that there is sufficient pressure on the blades and that the disc is tightly attached to the trowel.

NOTE :

The trowel is to be used only by experienced operators. They must have the knowledge of when the concrete is ready to be troweled , the angle of the blades and the operating speed. These instructions should be used as general guidance only.

Floating concrete

  • Use the float disc or the blades set at a small angle for floating.
  • The concrete should be sufficiently set before the floating operation takes place.
  • This must be determined by the operator.
  • Floating is done at a low speed. To have the machine move to the right bear down slightly on the handle. Lift gently on the handle to have machine move to the left.
  • Do not operate machine in one spot but keep it moving over the surface for either floating or finishing of concrete. If machine is allowed to stand in one spot while not operating , lift up on the handle to break loose the suction on the trowels and move to a new spot before starting to operate the machine.

Finishing concrete :

  • The finishing operation is carried out with the blades set at a large angle and at a high speed.

Stopping :

  • Release the Dead Man Control Handle.
  • Turn the motor switch to the "OFF" position.

Instructions For Lifting Machine :

  • Never walk or stand under a machine being lifted.
  • Use only the frame lifting hook (1) for lifting the machine.
  • Use only tested and authorised lifting equipment.

Extension Cords

When choosing an extension cord, make sure it has adequate wire size for safety. An undersized cord will cause a drop in line voltage resulting in a loss of power and overheating.The table below shows the correct wire size to use depending on cord length. If in doubt, use the next heavier cord size. On motors being used outdoors, use extension cords rated for outdoor use.

Improper use of extension cords can cause overheating and create serious fire or shock hazards. NEVER use worn or damaged cords
