4.4.1 New machines are supplied with finish blades as standard equipment. Finish
blades are flat on both edges and can be installed in either direction.
When installing combination blades, orient blades as shown
(a)
. This positions the
raised edges of the blade correctly for the clockwise rotation of the machine.
4.4.2 Secure blades to trowel arms with 1½" screws
(b)
. Dip threads of screws in
grease prior to installation. This will prevent concrete from cementing the screws in
place and will make removal of the blades easier later on.
4.4.3 Plug the remaining threaded holes in the blade brace with plastic plugs
(c)
to
prevent them from filling with concrete. Do not lift the trowel overhead with a float pan
attached, as the pan could fall off and strike personnel working in the vicinity.
4.5 Installing and Adjusting Handles
On new machines the pipe handle comes assembled with the pitch control (Twist or
Pro-Shift
®)
(j)
and stop switch
(n)
.
To install the pipe handle assembly:
4.5.1 Pull the pitch control cable
(d)
from bottom end of the tube and remove the nuts
from the cable.
4.5.2 Thread the cable through the handle base
(a)
and over the pulley
(c)
as shown.
4.5.3 Attach the pipe handle to the handle base with two M8x16 screws
(b)
. Secure the
screws using Loctite 243 or an equivalent medium-strength thread-locking compound.
Torque the screws to 22 Nm (16 ft.lbs.).
4.5.4 Push the
Pro-Shift
® handle all the way forward (away from the operator) OR turn
the twist pitch control handle counterclockwise as far as possible. Connect the cable to
the fork
(e)
as shown and adjust the cable nuts
(f)
so the cable is snug and the trowel
blades lay flat (0° pitch).
Steering Handle:
4.5.1 Install the steering handle
(g)
to the machine as shown. Secure the shoulder bolt
(k)
using Loctite 243, or equivalent.
4.5.2 Position the throttle lever
(h)
on the handle and fasten it in place.
4.5.3 On machines equipped with an operator present lever, mount the lever
(p)
as
shown. When installing, be sure that the tabs on the lever dig through the paint and into
the metal of the handle. This will insure a good electrical ground. Test the function of the
