HDA-SERIES Walk-BehindTrowel 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 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 an 11 HP or 13 HP gasoline engine. Refer to the engine owner’s manual for instructions regarding the operation and maintenance of your engine. Please contact your nearest Multiquip Dealer for a replacement should the original manual disappear or otherwise become unusable.

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 a centrifugal clutch.

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 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.

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.

CAUTION

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 HDA-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 20. When using the auxiliary tube, always use two 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.

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.
