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.
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

Operation PV 35A
wc_tx000754gb.fm 15
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.
