2.1 Laws Pertaining to Spark Arresters
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.

deep trench 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.
2.3.8 ALWAYS refill the fuel tank in a well-ventilated area.
2.3.9 ALWAYS replace the fuel tank cap after refueling.
2.3.10 ALWAYS check the fuel lines and the fuel tank for leaks and cracks
before starting the engine. Do not run the machine if fuel leaks are
present or the fuel lines are loose.

PV 35A Safety Information
2.4 Service Safety
A poorly maintained machine can become a safety hazard! In order
for the machine to operate safely and properly over a long period of
time, periodic maintenance and occasional repairs are necessary.
WARNING
2.4.1 DO NOT attempt to clean or service the machine while it is running.
Rotating parts can cause severe injury.
2.4.2 DO NOT crank a flooded engine with the spark plug removed on
gasoline-powered engines. Fuel trapped in the cylinder will squirt out
the spark plug opening.
2.4.3 DO NOT test for spark on gasoline-powered engines if the engine is
flooded or the smell of gasoline is present. A stray spark could ignite
the fumes.
2.4.4 DO NOT use gasoline or other types of fuels or flammable solvents to
clean parts, especially in enclosed areas. Fumes from fuels and
solvents can become explosive.
2.4.5 ALWAYS keep the area around the muffler free of debris such as
leaves, paper, cartons, etc. A hot muffler could ignite the debris and
start a fire.
2.4.6 ALWAYS replace worn or damaged components with spare parts
designed and recommended by Wacker Neuson Corporation.
2.4.7 ALWAYS disconnect the spark plug on machines equipped with
gasoline engines, before servicing, to avoid accidental start-up.
2.4.8 ALWAYS keep the machine clean and labels legible. Replace all
missing and hard-to-read labels. Labels provide important operating
instructions and warn of dangers and hazards.

2.6 Warning and Informational Labels
Wacker Neuson machines use international pictorial labels where
needed. These labels are described below:
Label Meaning
DANGER!
Engines emit carbon monoxide; operate only
in well-ventilated area. Read the Operator’s
Manual.
No sparks, flames, or burning objects near the
machine. Shut off the engine before refueling.
WARNING!
Hot surface!
WARNING!
Always wear hearing and eye protection when
operating this machine.
A nameplate listing the model number, item
number, revision number, and serial number is
attached to each unit. Please record the
information found on this plate so it will be
available should the nameplate become lost or
damaged. When ordering parts or requesting
service information, you will always be asked
to specify the model number, item number,
revision number, and serial number of the unit.

PV 35A Operation
3. Operation
3.1 Application
This machine is intended for on-site vibration of concrete for
foundations, walls, columns, slab work, etc. The self-contained design
allows free movement about the jobsite without the restrictions of an
electrical cord.
3.2 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.
3.3 Starting the Engine
See Graphic: wc_gr004492
3.3.1 If engine is cold, move the choke lever (a) to the CLOSED position
(a1). If engine is hot, set the choke to the OPEN position (a2).
3.3.2 Press the priming bulb (b) repeatedly until fuel can be seen in the clear
plastic fuel return tube (c).
3.3.3 Turn the engine switch to the ON position (d1).
3.3.4 Pull the starter grip (e) lightly until you feel resistance, then pull briskly.
Return the starter grip gently.
3.3.5 Gradually open the choke as the engine warms up (a2).
3.3.6 Open the throttle fully to operate equipment. (See “Operating the
Machine” for more information.)

3.5 Operating the Machine
The PV 35A vibrator features a unique pendulous design. This design
causes the vibrator to rattle and possibly feel off-center in rotation. This
is normal; the vibrator is not broken or damaged.
To prepare the machine for operation:
See graphic: wc_gr004498
3.5.1 Make sure that the engine has oil in it.
3.5.2 Turn the quick-disconnect coupler (a) clockwise and insert the vibrator
shaft (b). Once the vibrator shaft is inserted, turn the quick-disconnect
coupler counter-clockwise to lock the vibrator in position.

b
c
wc_gr004498
To operate the machine:
3.5.1 Start the engine and allow it to warm up for approximately 5–7 minutes.
3.5.2 Bring the engine up to full throttle (approximately 9000 rpm) by
squeezing the trigger (c).
3.5.3 Activate the vibrator action by striking the side of the vibrator head
against a solid object.
NOTE: Avoid slamming the nose of the vibrator head against solid
objects. Head-on impacts may damage the machine.
3.5.4 Begin vibrating by placing the vibrator head into the concrete.
NOTE: Do not submerge the head and shaft above the coupler
assembly.
wc_tx000754gb.fm 14
Page 15
Operation PV 35A
Operating tips:
3.5.1 NEVER turn the vibrator off while it is submerged in the concrete.
3.5.2 During use, insert the head quickly into the mix and then pull it out
slowly. Rapid removal is the main cause of poor concrete
consolidation. For best results, submerge head completely and try to
establish a symmetrical pattern for inserting and removing the head.
3.5.3 When moving around the jobsite, do not drag the vibrator head and
shaft on the ground.
3.5.4 Avoid touching forms and rebars when inserting the vibrator head into
the mix. This can transmit vibration to other areas of the mix which may
already be setting.
3.5.5 When the vibrator is out of the concrete for extended periods of time,
allow the engine to return to idle speed or simply turn the machine off .
3.6 When Vibration Is Complete
When you are finished using the vibrator:
3.6.1 Bring the engine RPM down to idle speed.
3.6.2 Lift the vibrator head out of the concrete
3.6.3 Shut off the engine by turning the engine switch to the OFF position.
3.6.4 Disconnect the vibrator shaft from the engine.
3.6.5 Rinse the vibrator head and shaft thoroughly with clean water. Do not
allow concrete to harden on these components.
3.6.6 See “Maintenance” chapter for extended storage procedures.

4.3 Air Cleaner
See Graphic: wc_gr004366
The engine is equipped with a foam element air cleaner. Service the
air cleaner frequently to prevent carburetor malfunction.
NOTICE: NEVER run engine without the air cleaner. Severe engine
damage will occur.
NEVER use gasoline or other types of low flash point solvents for
cleaning the air cleaner. A fire or explosion could result.
WARNING
To service the air cleaner (GX35 engine):
4.3.1 Press the latch tab (a) on top of the air cleaner cover (b) and remove
the air cleaner cover. Remove the foam element (c) and inspect it for
holes or tears. Replace the element if damaged.
4.3.2 Wash the element in a solution of mild detergent and warm water.
Rinse thoroughly in clean water. Allow the element to dry thoroughly.
Soak the element in clean engine oil and squeeze out excess oil. The
engine will smoke when started if too much oil is left in the foam.
4.3.3 Using a moist rag, wipe dirt from the air cleaner body and cover. Be
careful to prevent dirt from entering the carburetor.
4.3.4 Re-install the filter element and air cleaner cover.
