Introduction & Machine Specifications Introduction & Machine Specifications Clarke Technology’s newly designed Encore S2426 and L2426 automatic scrubbers are efficient and superior floor cleaning machines. The Encore uses two brushes to scrub a path 24 or 26 inches wide. A squeegee wipes the floor while the vacuum motor removes the dirty solution from the floor - all in one pass.
Procedures For Transporting How to Put the Machine Into a Van or Truck WARNING: This machine is heavy. Get assistance before attempting to transport or move it. Use two able persons to move the machine on a ramp or incline. Always move slowly. Do not turn the machine on a ramp. Do not stop and leave the machine on a ramp or incline. The loading ramp must be a minimum of 32" wide. WARNING: Machines can topple over if guided over the edges of stairs or loading docks and cause injury or damage.
Procedures For Transpoting (cont.) 11. Fasten the machine to the vehicle. Clarke Technology recommends a strap over the top of the machine and a strap to keep the machine from rolling forward or backwards. If this is not done, there is a possibility of the machine toppling over. Four tie down points (2 along each side of frame) are provided on machine for securing machine. How to Remove the Machine From a Van or Truck 1. Make sure there are no obstructions in the area. 2.
