BA-SERIES WALK-BEHIND TROWEL — PARTS & OPERATION MANUAL — REV. #3 (11/30/04) — PAGE 15
BA-SERIES TROWEL— GENERAL INFORMATION
BA-Series Walk-Behind Trowel 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 pitch control, 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
This trowel is available with either an 8.0 HP HONDA, 8.5 HP
ROBIN, or a 8.0 HP Briggs and Stratton 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 from
Whiteman. Please contact your nearest Multiquip Dealer for a
replacement should the original manual disappear.
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
either a centrifugal or manual clutch. See page 23.
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 either 3 or 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.
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.
Moving the BA-Series Walk-Behind Trowel
This walk-behind trowel is designed to be moved and handled
in several ways. The easiest way to lift the trowel is to use the
auxiliary lifting tube that is attached to the main handle. See
page 24, Figure 21. When using the auxiliary tube, always use
two persons to lift the trowel.
Some models have a
lifting bale (option) installed. A strap or
chain can be attached to the lifting bale, 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 either
three or 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 or manual clutch
depending on which trowel you have, will stop the engine
and bring the trowel to a halt.

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.
7. Centrifugal Kill Switch – In the event the operator loses
control of the trowel, this switch will shut-down the engine.
8. Auxiliary LiftingTube - Use this tube to lift the trowel onto
a slab.Tube is to be inserted into socket located in front of
the gearbox.
9. Weights – The trowel may be equipped with two 10 lbs.
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 lever.When this lever
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 exercise extreme CAUTION! Tube is spring-loaded,
severe injury could result if not disassembled correctly.
14. Guard Ring- NEVER! put hands or feet inside guard ring.
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 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.
18. V-Belt Cover – Remove this cover 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.

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 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 fuel 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
NOTE
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
BA-SERIES TROWEL— BASIC ENGINE
HONDA engine shown.
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.

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.
HandleTube 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.

CAUTIONCAUTION
CAUTIONCAUTION
CAUTION
The Quick-Pitch™ handle is spring loaded,
personal injury or damage could result from
improper handling or installation. Be careful
when installing this component.
NOTE
Considerable force may be required when
moving the Quick-Pitch™T-handle
forward or backward.
2. On Quick-Pitch™ models, pivot the T-handle back
(full pitch) (Figure 6). This will relax the spring inside the
handle tube. On either model, spread the handle bar ends
just enough to engage the teeth on the handle tube. Attach
the hand wheel assembly, position handlebar to desired
location, and tighten hand wheel firmly.
