SCT SERIES TROWEL— CONTROLS AND COMPONENTS

Figure 3. SCT SERIESWalk-Behind Trowels

Figures 3 shows the location of the basic controls or components,
for the SCT SERIEStrowel. Listed below is a brief explanation of
each control or component

1. Pitch Control - Turn this "Star Wheel" clockwise for increase
blade pitch, and counter-clockwise for decrease blade pitch

2. Hand Grip/Handle Bar – When operating the trowel, place
both hands on each grip to maneuver the trowel. Replace
hand grips when they become worn or damaged.

3. Throttle – Controls engine speed.

4. Engine – This trowel uses a Honda gasoline engine.

5. Centrifugal Safety Stop Switch – In the event the operator

loses control of the trowel, this switch will shut-down the
engine.

6. Trowel Lifting Point – Use a hoist, forklift, or other suitable
lifting device to lift the trowel on and off the concrete slab.

7. Engine ON-OFF Switch– Turn to the "ON" position for
starting the engine and to the "OFF" position to prevent the
engine from starting.

8. Main Tube - Houses throttle control and pitch cables.

9. Guard Ring- NEVER! put hands or feet inside guard ring.

10. V-Belt Cover – Remove this cover to gain access to the V-
belt. NEVER operate the trowel with this cover removed.

11. Trowel Arm – NEVER operate the trowel with a bent, broken

or out of adjustment trowel arm. If the blades show uneven
wear patterns or some blades wear out faster than others,
the trowel arm may need to be adjusted. Use the trowel
arm adjustment tool P/N 1817 to adjust the trowel arms.

12. Blades – This trowel is equipped with combination blades.
These blades are versatile and should take care of most
troweling needs. In addition float discs can be attached to
the trowel arms that will allow the trowel to float on "wet"
concrete.

13. Stabilizer Ring – Reduces trowel arm vibration. Helps
stabilize trowel arm.

SCT SERIES TROWEL— BASIC ENGINE

Figure 4. Engine Controls and Components

INITIAL SERVICING (ENGINE)

The engine (Figure 4) must be checked for proper lubrication and
filled with fuel prior to operation. Refer to the manufacturers engine
manual for instructions & details of operation and servicing.

1. Fuel Filler Cap – Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.

DANGER

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

).

, lever back toward operator

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.

NOTE

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.

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

WARNING

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.

10. Fuel Tank – Holds unleaded gasoline. For additional
information refer to engine owner's manual.

Clip-On Float Blades (Optional)

These blades will clip on to an existing installed blade, (Figure

27), allowing the finisher to "float" on “wet” concrete so that the
troweling operation can begin as early as possible. They can be
easily removed, so when the concrete is sufficiently cured, the
troweling operation can continue.

Float Discs (Optional)

These round discs (Figure 28) attach to the spiders and allow the
machine to “float” on “wet” concrete. The disc design allows early
floating and easy movement from wet to dry areas. They are also
very effective in embedding large aggregates and surface
hardeners.

Figure 27. Clip-On Float Blade

Figure 25. Combination Blade

Finish Blades (Optional)

These blades (Figure 26) have been specifically designed for
finish operations with this trowel. They will provide a premium
surface finishing capability from your trowel. They should only be
used after the concrete has set to the point where the trowel does
not sink into the concrete when placed on it.

Trowel Arm Adjustment Tool

If blades show uneven wear patterns or some tend to wear out
faster than others, the trowel arms may need to be adjusted. A
special tool P/N 1817, (Figure 29) is available that can be used
to adjust all of the trowel arms consistently.

Trowel Arm Adjustment

Shown in Figure 41 is the adjustment fixture with a trowel arm
inserted. As each trowel arm is locked into the fixture, the arm bolt
is adjusted to where it contacts a stop on the fixture. This will
consistently adjust all of the trowel arms, keeping the finisher as
flat and evenly pitched as possible.

1. Locate the trowel arm adjustment tool P/N 1817. Set the
adjustment tool for a clock-wise blade rotation, meaning the
fixture arm is in the "UP" position.

4. Loosen the locking nut on the trowel arm lever, then turn the
trowel arm adjusting bolt until it barely touches (.010") the
adjusting bolt on the fixture.

5. After the correct adjustment has been made, tighten lock nut
on trowel arm lever to lock in place.

6. Loosen locking bolts on adjustment fixture, and remove
trowel arm from fixture.

7. Repeat steps 2-7 for the remaining trowel arms.

Re-Assembly

1. Clean and examine the upper/lower wear plates and thrust
collar. Examine the entire spider assembly. Wire brush any
concrete or rust build-up. If any of the spider components are
found to be damaged or out of round, replace them.

2. Make sure that the bronze trowel arm bushing is not damage
or out of round. Clean the bushing if necessary. If the bronze
bushing is damage or worn, replace it.

3. Reinstall bronze bushing onto trowel arm.

4. Repeat steps 2 -3 for each trowel arm.

5. Make sure that the spring tensioner is in the correct position
to exert tension on the trowel arm.

6. Insert all trowel arms with levers into spider plate (with bronze
bushing already installed) using care to align grease hole on
bronze bushing with grease hole fitting on spider plate.

7. Lock trowel arms in place by tightening the hex head zerk
grease fitting and jam nut.

8. Re-install the blades back onto the trowel arms.

9. Install stabilizer ring onto spider assembly.

10. Reinstall lower wear plate,

ring

the spider shaft. Make sure that there is little or no lateral
movement between the thrust collar and the spider shaft.
