BA-SERIES TROWEL— CONTROLS AND COMPONENTS
Figures 3 shows the location of the basic controls or components,
for the BA-Series trowel. Listed below is a brief explanation of
each control or component
1. Quick Pitch™ Control Handle – To adjust the pitch of
the blades, grasp the handle then squeeze and either move
the handle forward or backward to achieve the desired
blade pitch.
2. Handlebar Adjuster – Change the angle/height of the
handle bars by loosening star wheel, adjust handlebars to
desired location, tighten starwheel firmly to hold handlebars
in that position.
3. 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.
4. Throttle Control Grip – Controls the speed of the engine.
Rotate the hand grip away from the operator to increase
engine speed (high), toward the operator to decrease
engine speed (low).
5. Throttle – Controls engine speed when throttle control
grip is rotated.
6. 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.
15. Engine – This trowel uses Honda, Robin and Briggs and
Stratton type gasoline engines.
16. 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.
17. Blades – This tro wel 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.
18. V-Belt Cover – Remo ve this cov er to gain access to the V belt. NEVER operate the trowel with this cover removed.
20. Stabilizer Ring – Reduces trowel arm vibration. Helps
stabilize trowel arm.
7. Centrifugal Engine-Off Safety Switch – In the event the
operator loses control of the trowel, this switch will shutdown the engine.
8. Auxiliary Lifting Tube - Use this tube to lift the trowel onto
a slab. T ube is to be inserted into socket located in front of
the gearbox.
9. Weights – The trowel may be equipped with two 4.5 kg
(10 lb.) weights. The weights may be removed to reduce
the operating weight of the trowel.
10. Trowel Lifting Point – Insert the auxiliary lifting tube here.
See Figure 21.
11. Pitch Control (standard models) - Turn this "Star Wheel"
clockwise for increase blade pitch, and counter-clockwise
for decrease blade pitch.
12. Clutch Lever - Clutch engagement le ver . When this le ver
is engaged, the blades will begin to rotate. May be used
with either Quick Pitch™ or Standard handle.
13. Main Tube - When disassembling components inside the
tube ex ercise extreme CAUTION! Tube is spring-loaded,
sev ere injury could result if not disassembled correctly .
14. Guard Ring- NEVER! put hands or feet inside guard ring.

BA-SERIES TROWEL— BASIC ENGINE
Figure 4. Engine Controls and Components
INITIAL SERVICING
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. The
engine shown above is a HONDA engine, operation for other
types of engines may vary somewhat.
1. Fuel Filler Cap – Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT ov er 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
SLOW
advanced forward
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.
, 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 fuel 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 according to engine manufacturer's
instructions. Clean spark plug once a week.
9. Muffler – Used to reduce noise and emissions.
10. Fuel Tank – Holds unleaded gasoline. For additional
information refer to engine owner's manual.
11. Oil Drain Plug – Remove this plug to remove oil from the
engine's crankcase.
12. Dipstick/Oil Filler Cap – Remove this cap to determine if
the engine oil is low. Add oil through this filler port as
recommended in Table 3.
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 .

BA-SERIES TROWEL — ASSEMBLY AND INSTALLATION
Assembly and Installation
Before the trowel can be put into operation there are some
components that must be installed before the trowel can be used.
This section provided general instructions on how to install those
components. Instruction sheet P/N 20485 provides further details
for the handle assembly.
Handle Tube Installation (All Models)
1. Install the
handle tube
to the gearbox as shown in (Figure 5).
The mounting hardware should be contained in the shipping
container.

the hand wheel assembly, position handlebar to desired
location, and tighten hand wheel firmly .
CAUTIONCAUTION

(Figure
Clip-On Float Blades (Optional)
These blades will clip (Figure 34) on to an existing installed blade,
allowing your finisher to float on “wet” concrete so that the
troweling operation can begin as early as possible. They are
easily removable, so that after the floating operation, when the
concrete is sufficiently cured, they can be removed to expose the
finish blades for continued troweling.
Float Discs (Optional)
These round discs (Figure 35) attach to the spiders and allow the
machine to “float” on “w et” concrete. The disc design allows early
floating and easy movement from wet to dry areas. The y are also
very effective in embedding large aggregates and surface
hardeners.

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.
