JA-SERIES WALK-BEHIND TROWEL — PARTS & OPERATION MANUAL — REV. #6 (11/14/05) — PAGE 15

JA-SERIES TROWEL— GENERAL INFORMATION

JA-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 5.5 HP HONDA, 6 HP

ROBIN, or a 5.5 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 shipping from

Whiteman. 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 or electric motor 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

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 JA-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

CAUTION

Blades

The blades of the trowel finish the concrete as they are rotated

around the surface. Blades are classified as

combination

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 which trowel you have, will stop the engine and

bring the trowel to a halt.
