Pre-Operating Instructions - cont’d SECTION 2 OPERATIONS Before starting riding trowel, locate and identify the operational and visual controls pertaining to the operation of the riding trowel. 1) Sit down correctly on the riding trowel seat. DO NOT attempt to start the riding trowel without an operator in the seat.
SECTION 2 OPERATIONS To utilize your Allen Engineering MSP450 Rider to its fullest capacity the machine should be driven in the direction the operator is facing. This will fi nish the widest possible area while giving the operator an excellent view of the slab surface about to be troweled. When the machine reaches the end of the slab make a 180 degree turn and repeat the straight line of direction to the other end of the slab.
Page 37
Operating Instructions SECTION 2 OPERATIONS With the operator in the seat, show them the functions of the joysticks [B] and [C] and how to start the machine. A hard level concrete slab with water on the surface is an ideal place for an operator to practice with the machine.
