VIBRATOR MAINTENANCE
Flexible Shaft Greasing Instructions
Remove, clean, and grease the shaft core and bearings
every 50 hours. Use Shell Durina EP2 or equivalent
grease. Wipe off old grease completely and apply new
grease evenly to the shaft. Reference the flexible shaft
maintenance instructions shipped with the shaft.
DO NOT allow water, dust or foreign debris to enter the
flexible hose while reassembling.
If the flexible shaft becomes too hot to hold, the unit
may require lubrication. Lubricate the inner core. This
will reduce heat buildup.
Vibrator Head
Vibrator heads should be inspected and lubricated every
100 hours of operation. Reference the vibrator head
maintenance instructions shipped with the vibrator head.
ALWAYS inspect the vibrator head for damage to the
threads after every reassembly. Replace housing and
head as necessary.
Measure vibrations per minute at the vibrator head
to determine if the bearings in the head require
replacement.
NOTICE
When replacing the flexshaft assembly, make sure the
replacement core has been lightly greased before use.
Place a handful of clean grease (Shell Durina EP2 high-
temperature, high-pressure grease or equivalent) in a
shop cloth and slide the clean core through the grease
as you feed it back into the shaft housing.
NOTICE
After every job, or
every 50 hours, the shaft should
be disassembled, cleaned, inspected, lubricated, and
reassembled.
NOTICE
Use heat to break down the Loctite
®
while unthreading
the head from the shaft. This will prevent damage to
the threads.
MAINTENANCE
Quick Disconnect Lock
A small amount of lightweight oil should be used on the
quick disconnect locking mechanism (Figure 31) to lubricate
the locking pin and spring and prevent concrete buildup.

PREPARATION FOR LONG-TERM STORAGE
For storage of the vibrator over 30 days, the following is
required:
Drain the fuel tank completely, or add STA-BIL
®
to the
fuel.
Run the engine until the gasoline in the carburetor is
completely consumed.
Completely drain the oil from the crankcase and refill
with fresh oil.
Remove the spark plug, pour 2–3 cc of SAE 30 oil into
the cylinder, and crank slowly to distribute the oil.
Slowly rotate the engine a few times with the starter rope
and install a new plug.
Pull out the starter rope slowly and stop at the
compression point.
Clean all external parts of the engine and frame with a
soft cloth.
Cover the unit and store in a clean, dry place.
