Multiquip 21362 ユーザーズマニュアル

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.

This trowel is available with an 8.0 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 from
Whiteman. Please contact your nearest Multiquip Dealer for a
replacement should the original manual disappear.

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.

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).

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.

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.

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 

assembly.

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.

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.  When using the auxiliary tube, always use 

persons to lift the trowel.

Some models have a 

lifting bail (option) installed. A strap or

chain can be attached to the lifting bail, 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.

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.
