2.1 Operating Safety

Notice: State Health Safety Codes and Public Resources Codes

specify that in certain locations spark arresters be used on internal

combustion engines that use hydrocarbon fuels. A spark arrester is a

device designed to prevent accidental discharge of sparks or flames

from the engine exhaust. Spark arresters are qualified and rated by

the United States Forest Service for this purpose.

In order to comply with local laws regarding spark arresters, consult

the engine distributor or the local Health and Safety Administrator.

Familiarity and proper training are required for the safe operation of

equipment! Equipment operated improperly or by untrained personnel

can be dangerous! Read the operating instructions contained in both

this manual and the engine manual and familiarize yourself with the

location and proper use of all controls. Inexperienced operators should

receive instruction from someone familiar with the equipment before

being allowed to operate the machine.

2.1.1 NEVER touch the engine or muffler while the engine is on or

immediately after it has been turned off. These areas get hot and may

cause burns.

2.1.2 NEVER use accessories or attachments that are not recommended by

Wacker. Damage to equipment and injury to the user may result.

2.1.3 NEVER leave machine running unattended.

2.1.4 NEVER operate the machine with the belt guard missing. Exposed

drive belt and pulleys create potentially dangerous hazards that can

cause serious injuries.

2.1.5 NEVER run machine indoors or in an enclosed area unless adequate

ventilation, through such items as exhaust fans or hoses, is provided.

Exhaust gas from the engine contains poisonous carbon monoxide

gas; exposure to carbon monoxide can cause loss of consciousness

and may lead to death.

2.1.6 ALWAYS wear protective clothing appropriate to the job site when

operating equipment.

2.1.7 ALWAYS wear hearing protection when operating equipment.

4. Operation

4.1 Application

This screed is a modern, high production machine intended to provide

consolidation of concrete while striking off and closing concrete

surfaces. The vibratory motion, consolidation, and closing action are

controlled by the engine speed. Wacker screeds are easily put

together to form desired lengths for all finishing applications. Finishing

rates will depend on operator skill and job conditions.

DO NOT use this machine for any application other than screeding

concrete.

4.2 Recommended Fuel

The engine requires regular grade unleaded gasoline. Use only fresh,

clean gasoline. Gasoline containing water or dirt will damage fuel

system. Consult engine owner’s manual for complete fuel

specifications.

4.3 New Machine Set-up

See Graphic: wc_gr000342

Screeds are shipped from the factory with the engine, beltguard, and

end winch section removed. These components need to be

Operation SP/HP/HPG /...

wc_tx000018gb.fm 18

4.5 Installing Screed Sections

See Graphic: wc_g000344

Wacker screed sections are connected in two places: at the top with T-

bolts (a) and at the bottom with a connector plate (b).

Each screed section has a coarse and a fine side, determined by the

top tube T-bolt connector threads. These T-bolts are critical to

alignment of the screed, so it is important to insure the integrity of the

threads.

The connector plate permanently mounts to the coarse end of the

screed section. It is secured to the section with shoulder bolts (c), lock

nuts (d) and lock washers (e). The connector plate also carries a

flange bearing (f) that guides and aligns the eccentric shaft (g).

Note: Remember to always leave the connector plate attached to the

coarse section end and disconnect from the fine side.

For initial setup:

4.5.1 Lay the sections of screed on a flat surface and install the connector

plate (b) to the coarse side.

4.5.2 Align the back T-blades and slide the two sections together while

guiding the eccentric shaft (g) into the mating surface of the flange

bearing (f).

Note: While assembling the sections, make sure that the T-bolts are

threaded into the top tube so they don’t make contact with each other

and impede the alignment of the connector plate.

Once the sections are in place, you may proceed with loosly bolting the

connector plate to the fine side of the screed. A tapered pin punch (h)

inserted through the bolt holes will aid in the alignment of the bracket.

Repeat this until all remaining mounting hardware is in place.

At this time, the T-bolts can be adjusted so that they are at an equal

distance between the assembled sections (i). Install the connecting

hardware (k) and tighten. Leave the jam nuts (m) loose for the next

step which is truing the screed.

Note: Once T-bolts have been adjusted at an equal distance, tighten

all hardware making sure screed sections stay level.
