Stopping

To stop trowel movement, return joystick(s) or control levers

 

to their

neutral position and release pressure on the throttle foot pedal.

To stop the engine, turn the keyswitch to “O” (off).

4.7

Operation

To utilize your WACKER Riding Trowel to its fullest capacity, the
machine should be driven in the direction that 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° U-turn, and repeat
the straight line of direction to the other end of the slab. 

Note:

 

During the break-in period, run the engine at 50% of full throttle.

Refer to Section New Machines.

NOTICE

: DO NOT

 use excessive pressure on the control levers.

Excessive pressure does not increase the reaction time of the machine
and can damage the steering controls.

NOTICE

:

 Attempting to use the trowel too early in the curing stage of

the concrete may result in an undesirable finish. Only experienced
concrete finishers should operate the trowel.
