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.

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

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.
