2.1 Operating Principle

The following instructions were compiled to provide you information on how to obtain long
and trouble free use of the machine. Periodic maintenance of the machine is essential.
Read the manual carefully and thoroughly familiarize yourself with the machine and all it's
functions. Failure to do so may injure yourself or a bystander.
2.2 Application—Standard Features
Your new Power Trowel comes standard with many features to enhance productivity,
performance and safety. Listed below are just a few of these features.
1. Safe Stop Switch—The switching mechanism of this switch should operate freely and should
always be kept in this condition. With the switch in the OFF position, the engine should not
start or run. The purpose of this switch is to stop the engine in a runaway situation, (i.e. the
operator releasing the handle during operation).
2. Adjustable Throttle—Located in a convenient location, this push-pull throttle control can be
set to provide any blade speed from 50 to 130 RPM, and located in place at the desired
operating speed.
3. Bent Arm Adjustable—Allows blades to be adjusted to compensate for bent arms caused by
dropping or mishandling the trowel. Can be easily adjusted on-site for consistent finishing.
4. Heavy Duty Ring Guard—Protects operator and unit while providing lower center of gravity
which contributes to unit stability and performance.
5. Cast Iron Spider—Extra strong for insure alignment. Also contributes to lower center or
gravity for increased trowel performance.
6. Adjustable Handle—Can be positioned to provide comfort and control for any operator's
height.
7. Tilt Adjustment Knob – adjusts the angle of the blades for different curing stages and
conditions of the concrete. Turning the knob clockwise increases the angle of the blades to
the concrete. Turning the knob counter-clockwise flattens or decreases the angle of the
blades.
