SAVE THESE INSTRUCTIONS

Northrock flexible shaft vibrators are built to the highest standards
of both quality and function. When properly assembled and maintained you will
receive many hundred hours of service from these units. Please take a few
minutes to read the assembly, maintenance, and safety instructions before
attempting to operate the vibrator.
Assembly Instructions:
! Be sure unit is unplugged and switch is in off position before proceeding.
1- Insert inner flexible core to motor adapter and then screw outer casing
on to motor. Tighten securely using wrench flats on motor and a pipe
wrench on the metal part of the flexible casing.
2- Apply adhesive sealant to threads at the vibrator head end to prevent water
from entering and to lock the head on. Secure head to shaft using wrench flats
provided on the head and a pipe wrench on the metal part of the flexible casing.
Note: The unit is now ready for operation, but with a new flexible shaft it
will take a few minutes for the grease to run itself in. For this short period
it is normal for the flexible shaft to rattle, and the motor speed to be
somewhat slower. (3-5 minutes)
Maintenance Instructions:
Motor: - keep housing and air filter clean to allow for proper cooling
- check brushes, switch boot, and electric cord for wear and replace
when worn
- motor bearings require no additional lubrication, replace when worn
Shafts: - inspect inner cores for lubrication after approx. 50 hours of
operation as follows: remove core on to a clean surface free of dirt
and grit, inspect core for dry areas, if lubrication is required wipe
core with cloth, reinsert core into casing applying approx. 1/16"
thick coating of high quality lithium grease. (available in 1lb cans
from the factory) Do not over grease the flexible shaft as this will
cause excess drag on the motor, and the shaft to get hot.
Heads: - heads are sealed at the factory since it is extremely important to keep
contaminants out, therefore they require no field maintenance
