Introduction
WHENEVER HANDLING GASOLINE.
LOCATION AND USE OF CON-
TROLS
Before operating this trowel, it is important to
familiarize yourself, and any other personnel
who will be using it, with the location and
proper use of the controls to insure safe and
efficient operation:
A - HANDLE ADJUSTMENT KNOB - to
adjust the handle for maximum operator
comfort and control, simply turn the knob
counterclockwise one-quarter turn maxi-
mum to loosen, move handle to desired
position and tighten knob to lock handle in
place.
B - THROTTLE CONTROL - this is a push-
pull type throttle control which can be
locked at any desired blade speed to meet
varying job conditions. To use, simply push
or pull the throttle control to obtain the
desired blade speed. To lock the throttle at
the speed, turn the control clockwise. To
unlock the throttle for further adjustments,
turn the control counter clockwise approxi-
mately 1/4 turn.
C - DYNA-CLUTCH LEVER - this is a
patented feature which acts as a safety
device to stop the trowel from spinning out
of control if the operator lets go of the
handle. It also allows the operator to control
the engagement and disengagement of the
trowel blades independent of engine speed.
To use, simply move the lever all the way up
to the RUN position to engage the trowel
blades. To stop the blades from turning,
push the lever all the way down to STOP
position. In the event that the operator lets
go of the handle while the blades are
turning, the centrifugal force from the swing
of the handle will throw the Dyna-Clutch
lever to the STOP position. This prevents
the unit from spinning out of control and
causing injury to personnel or damage to the
trowel and fresh concrete. Since the Dyna-
Clutch system disengages the blades from
the engine, rather than shutting down the
engine to stop the blades, time is saved in
getting the unit operating again. The
operator simply moves the Dyna-Clutch
lever to RUN position instead of having to
restart the engine and readjust engine speed.
D - 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 counterclockwise flattens or
decreases the angle of the blades.
E - ProPitch™ Handle Option -adjusts the
agnle of the blades for different curing stage
and conditions of the concrete. Lift handle
upwards to increase angle of the blades to
the concrete. Depress trip button to release
lock and decrease the angle of the blades.
