SCT SERIES WALK-BEHIND TROWEL — PARTS & OPERATION MANUAL — REV. #3 (03/30/05) — PAGE 15
SCT SERIESTROWEL— GENERAL INFORMATION
SCT SERIESWalk-BehindTrowel Familiarization
This walk-behind trowel is designed for the
floating and
finishing of concrete slabs.
Take a walk around the trowel. Take notice of all the major
components (see Figure 3, pages 16 and 17) like the engine,
blades, quick adjust control, (on those equiped models), air
cleaner, centrifugal stop switch etc. Check that there is always
oil in the engine.
Read all the safety instructions carefully. Safety instructions will
be found throughout this manual and on the trowel. Keep all
safety information in good, readable condition. Operators should
be well trained on the operation and maintenance of the trowel.
Before using your trowel, test it on a flat watered down section of
finished concrete that is free of any debris and other objects.
This trial test run will increase your confidence in using the trowel
and at the same time it will familiarize you with the trowel’s
controls. In addition you will understand how the trowel handles
under actual conditions.
Engines
The 36" trowel is available with a 5.5 HP HONDA or an 8.0 HP
HONDA gasoline engine while the 46" trowel is available with
an 8.0 HP HONDA or an 11.0 HP HONDA gasoline engine.
Refer to the engine owner’s manual for instructions regarding
the operation and maintenance of your engine. The engine
manual is included with your trowel at the time of shipment.
Please contact your nearest Multiquip Dealer for a replacement
should the original manual disappear or become unusable.
Drive System
Power is transferred from the engine to the gearbox input shaft
via a V-belt or pulley drive system.The pulley engages using a
centrifugal clutch.
Gearbox
The
gearbox is located beneath the engine and transfers power
to the
rotor or spider assembly. The gearbox controls the
rotational speed of the trowel and is equipped with two shafts
(input and output).
Spider
The vertical output shaft of the gearbox connects to a cast hub
called the
spider . The spider has 4 arms that extend outward
that are used for attachment of blades or other accessories.
Remember as the gearbox output shaft rotates so does the spider
assembly.
Moving the SCT SERIESWalk-Behind Trowel
This walk-behind trowel is designed to be moved and handled
in several ways. One way to lift the trowel is to use an
optional
lifting tube
. See page 24, Figure 20. When using the lifting
tube, always use
two persons to lift the trowel.
These models have a
lifting bail installed so strap or chain can
be attached, allowing a forklift or crane to lift the trowel up onto a
slab of concrete. Use a lifting device of adequate lifting capacity
to lift the trowel.
Training
For proper training, please use the “TRAINING CHECKLIST”
located in the front of this manual (Page 6). This checklist will
provide an outline for an experienced operator to provide training
to a new operator.
CAUTIONCAUTION
CAUTIONCAUTION
CAUTION
Blades
The blades of the trowel finish the concrete as they are rotated
around the surface. Blades are classified as
combination
(8 inches wide), float (10 or 8 inches wide), and finish (6
inches wide). This trowel comes equipped with four blades
per rotor equally spaced in a radial pattern and attached to
vertical rotating shaft by means of a
spider assembly.
Centrifugal Stop Switch
In the event of a trowel runaway condition, (operator releases
the handle), a
centrifugal stop switch will stop the engine
and bring the trowel to a halt.
NEVER attempt to lift the trowel by yourself.
ALWAYS get the assistance of another
person to help lift the trowel or use a crane
or lifting device to move the trowel.

gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop
the flow of fuel.
6. Choke Lever – Used in the starting of a cold engine, or in
cold weather conditions. The choke enriches the fuel
mixture.
7. Air Cleaner – Prevents dirt and other debris from entering
the air intake system. Remove wing-nut on top of air filter
cannister to gain access to filter element.
8. Spark Plug – Provides spark to the ignition system. Set
spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Clean
spark plug once a week.
9. Muffler – Used to reduce noise and emissions.
Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas
while the engine is running or immediately after
operating. NEVER operate the engine with the
muffler removed.
10. Fuel Tank – Holds unleaded gasoline. For additional
information refer to engine owner's manual.
DANGER
WARNING
SCT SERIESTROWEL— BASIC ENGINE
Adding fuel to the tank should be done only when
the engine is stopped and has had an opportunity
to cool down. In the event of a fuel spill, DO NOT
attempt to start the engine until the fuel residue has been completely
wiped up, and the area surrounding the engine is dry.
2. Throttle Lever – Used to adjust engine RPM speed (lever
advanced forward
SLOW , lever back toward operator
FAST ).
3. Engine ON/OFF Switch – ON position permits engine
starting, OFF position stops engine operations.
4. Recoil Starter (pull rope) – Manual-starting method. Pull
the starter grip until resistance is felt, then pull briskly and
smoothly.
Operating the engine without an air
filter, with a damaged air filter, or a
filter in need of replacement will
allow dirt to enter the engine, causing
rapid engine wear
