4.3 Features and Controls-Vanguard Engine (electric steer)
See Graphic: wc_gr000696
The Riding Trowel features a seat with an integrated “operator
presence” system, which works in conjunction with a throttle mounted
switch. This system allows the engine to remain running (idling) with
no operator seated in the seat, as long as the throttle is not depressed.
This system meets all safety requirements and eliminates the need for
a foot-operated “kill switch”.
To familiarize a new operator with the Riding Trowel the following
steps should be taken:
4.3.1 With the operator in the seat, show him or her the functions of the
joysticks
(c) and how to start the machine.
4.3.2 Have the operator practice steering the trowel. A hard concrete slab
slightly wetted with water is an ideal place for an operator to practice
with the machine. For this practice, pitch the blades up approximately
¼" 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° turns. The best control is achieved at full rpm.
