1.9 Operating
To utilize your Allen
®
Rider to its fullest capacity the machine should be driven in the direction the operator is
facing. This will finish 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. To familiarize a new operator with the Riding Trowel the fol-
lowing steps should be taken.

2. With the operator in the seat, show him the functions of the control levers (B) and (C) and how to start the
machine. (refer to page 1A-10)
A hard level concrete slab with water on the surface is an idea place for an operator to practice with the machine.
For practice pitch the blades up approximately 1/4" on the leading edge. Start by making the machine hover in one
spot and then practice driving the machine in a straight line and making 180 degree turns. Best control is achieved
at full RPM.
CAUTION:
After starting engine fully engage the throttle. This allows the engine and the hydraulic fluid to warm up
quicker. NOTE: If you start out at a low RPM this will cause the machine to have a slower reaction time between
movement of the joysticks and the rotors.
CAUTION: DO NOT
use excessive pressure on the joysticks (Power Steering). Excessive pressure does not
increase the reaction time of the machine and can damage steering controls.
1.10 Stopping
To stop the trowel's movement, return the control levers (C) and (B) to their neutral position and release pressure on
the right foot pedal (E). You will need to pull the engine throttle lever (I) towards the rear of the machine. This will
reduce the speed of the engine. It is not recommended to leave the engine throttle lever in the forward position if
the rotors are not turning.
