Putting Into Service

Before packing and shipping, this Power Trowel was run and
tested at the factory. If there are any problems, please let us know.
Fill out and send the warranty-registration card supplied with the
machine. All warranties are void unless this card is on file with
us.

Before putting your new finisher into service, read all manuals
and instructions carefully. Improper setup, use or maintenance
of your equipment could result in personal injury or damage to
equipment.

The purpose of this section of the manual is to explain the
intended setup, use and maintenance of this equipment.

Assembly

Note: READ THESE INSTRUCTIONS CAREFULLY BEFORE
ATTEMPTING TO ASSEMBLE ANY COMPONENTS.

HANDLE ASSEMBLY — QUICK PITCH™

The QUICK PITCH handle is spring loaded, personal injury or
damage could result from improper handling or installation.
Attach the handle tube as shown (Step 1). Bolts are to be inserted
from the bottom side of the handle. Note that the bolt on the engine
side must have a washer between the gearbox and the nut. The

Remove one brass nut from the cable end. Thread the second
brass nut towards the cable as far as possible (Step 3). Insert the
cable end into the yoke as shown. Replace the brass set nut on
the cable end. Tighten the set nut by hand as far as possible to
remove slack from the cable (Step 4). Using a wrench, tighten the
locking nut on the other side of the boss to lock the cable in place
(Step 5).

second bolt carries the auxiliary lift handle bracket in the place
of a washer.

After the handle is connected to the trowel, grasp the QUICK
PITCH control from operator’s position. Pull the adjustment
trigger on the QUICK PITCH handle and push the entire handle
towards the engine as far as possible (Step 2). This will compress
the spring inside the handle. Considerable force may be required
to do this! Release the trigger to lock the spring in this compressed
position.

Preload adjustment for QUICK PITCH

After the handle is installed on the machine, spring preload
adjustment will be required. Locate the adjustment screw on the
underside of the handle. A decal has been placed there to assist
in the adjustment. Turn the screw to adjust until it lines up with the
arrow on the decal matching your setup. Test pitch control operation.
Adjust if necessary.

If you want to be able to increase the blade pitch using less arm
force, adjust the block away from the gearbox. Be aware, this will
also require more force to decrease the blade pitch. If you want
to be able to decrease the blade pitch using less arm force, adjust
the block toward the gearbox.

HANDLE ASSEMBLY — STANDARD HANDLE

Turn the pitch adjustment knob (located on the operator end of the
handle) counter-clockwise until resistance is felt.

Attach the handle tube to gearbox as shown in the QUICK PITCH
handle installation. Bolts are to be inserted from the bottom side
of the handle. Note that the bolt on the engine side must have a
washer between the gearbox and the nut. The second bolt carries
the auxiliary lift handle bracket in the place of a washer.

Remove one brass nut from the cable end. Thread the second
brass nut towards the cable as far as possible. Insert the cable end
into yoke as shown in the QUICK PITCH installation. Replace the
brass set nut on the cable end. Tighten the set nut by finger as far
as possible to remove slack from the cable. Using a wrench,
tighten the locking nut on the other side of the boss to lock the cable
in place.

SAFETY KILL WIRE

Locate the red wire protruding from the handle tube and connect
it to the red wire tail on the engine. Test to insure proper operation!

HANDLE HEIGHT ADJUSTMENT

If handle height adjustment is desired, a handle wedge kit can be
purchased for your machine by ordering Part Number 2576 from
your Multiquip dealer. These wedges are placed between the
handle and the gearbox to adjust the operating height of the
handle. This kit comes complete with wedges, new bolts and
installation instructions. This will move your operating handle
position up or down approximately 3” (76mm).

THROTTLE CABLE INSTALLATION

Note: A red wire piece has been placed on the engine
throttle assembly to show where the throttle cable from
your handle should be placed.
