Switching Blade Positions
See Graphic: wc_gr000255
To switch the position of the blades from the non-overlapping position
(f)
to the overlapping position
(g)
:
5.3.1
Place the trowel on a flat, level surface.
5.3.2
Remove the screws
(a)
holding the blade to the trowel arm.
5.3.3
CRT 48 only - Remove the plastic plug from the off-set screw hole
(b)
and place it into screw hole
(c)
to prevent it from filling with concrete.
5.3.4
Raise the trowel very slightly to take the weight off of the blades. Use
a fork lift or dolly jacks.
5.3.5
Slide the blades to align them with the screw holes
(d)
.
Trowel blades may be sharp! Use adequate protection to keep from
cutting skin or clothing!
5.3.6
Lower the trowel so the arms are securely against the blades.
5.3.7
Secure the screws into the screw holes
(d)
. Dip the threads of the
screws in grease prior to installation. This will prevent concrete from
cementing the screws in place and make removal of the blades easier
later on.
Note:
Do not operate the trowel unless all blades are either in the
overlapping or non-overlapping position.
To switch the position of the blades from overlapping to non-
overlapping, reverse the process.
Blade Arm Adjustment Procedure
To eliminate wobble:
5.3.1
Pitch the blades flat.
5.3.2
Tighten lock nut located at the bottom of each pitch cable. Maximum
cable play should be no more than 3.18 mm (.125”) or the width of the
cable.
5.3.3
Set gap on all adjustable links to 4.58 mm (.180”).
