2. Place the flexible drive with installed quick disconnect fitting up to the quick
disconnect on the motor drive. Be sure the core engages in the motor drive.
Turn the large hand nut counter clockwise until tight (hand nut has left
hand threads to insure it will remain tight while operating the system).
3. Before attaching the head, check the length of core
extending from the head end of the flex drive. If this
length is greater than 2-3/4”, twist the core while
pushing it into the casing to make sure it is fully seated
in the motor. If the exposed core is greater than 2-3/4”
when it is fully seated in the motor it may bind and
cause damage to the core, casing, or head. Do not use
the system. Contact your dealer or Global Manufacturing at 1-800-551-3569.
4. To attach the head to the flex drive, be sure the core engages the drive
coupling in the head. First apply two layers of Teflon® tape to the casing
threads then tighten the head in a clockwise direction. Use a crescent wrench
on the machined flats on the head and channel locks or a small pipe wrench
on the casing fitting to make sure the connection is secure.
5. Use only fresh unleaded gasoline with a pump octane rating of
86
or higher.
Do not over fill tank.
III. Operation
3.
Do NOT leave out the Teflon® tape! It is required to provide a watertight
seal between the various components of your vibrator system and pre-
vents the connections from coming loose during operation. If Teflon®
tape or a similar sealant is not used, the components can be damaged by water that pen-
etrates this connection, or the components can come apart and be lost in the concrete.

operation, could cause malfunction in which you could be seriously
