- CLEAR AIR SUPPLY LINE: Before connecting vibrator, clear the compressed air supply line of possible impurities,
contaminants and water.
- LUBRICATE: Every day or every four hours of continuous service, pour a ½ teaspoon of non-detergent (Viscosity 20
to 30 SAE) oil into the quick release coupling. NOTE: An optional oiler/strainer is available (See Page 3)
WARNING: So as to facilitate shipment, new or repaired units are not lubricated before delivery to customers.
WARNING: Do not use hydrocarbons and especially do not use fuel oil for lubricating purposes.
- CONNECT: Connect the vibrator to the quick release coupling securely. Insure that locking pin is in place.
- START: To start vibration, rotate the variable control assembly near the quick release coupling. It is sometimes
necessary to tap the head to begin vibration. If the vibration intensity drops, check that the filters are not clogged or that
hoses are not kinked.
- STORAGE: To properly store unit after use, hang the vibrator with the head up and set the handle (variable control
assembly) in the open position to permit the discharge of possible impurities, contaminants and water.
VIBRATOR HEAD:
- Reverse previous procedures.
- Replace the following parts each time the vibrator head
has been disassembled:
- Vane (5) - O-Rings (2 & 16)
- Filter (on quick disconnect) - Hose Clamps (9 & 14)
- Slightly lubricate all parts before reassembly.
- Adjust the new vane (5) so that it slides snug in the
groove in the rotor (4). Note: Be sure that vane (5) slots
are facing away from cutout in rotor (4).
- Check the condition of front (3) & rear (7) flange &
replace them if there is a hollow area where the rotor
turns.
- Reassemble tip (1) & outer hose holder (11) making
sure that the O-rings (2) are in place.
VARIABLE CONTROL ASSEMBLY:
- Reverse previous procedure.
- Replace O-rings on body making sure you do not cut
O-rings when sliding body back into bushing.
- Reassemble all hoses onto the vibrator head assembly
and reattach the on/off control valve.
* When screwing tip and hose holder into housing torque
as follows:
- BD 35 37ft/lbs - BD 65 434 ft/lbs
- BD 55 246 ft/lbs - BD 75 636 ft/lbs
VIBRATOR HEAD:
- Hold vibrator head housing (6) in a vice and unscrew
the tip (1). (Right Hand Thread)
- Remove vibrator head from vice and tap vertically on a
wooden block. This will aid in the removal of the front
flange (3) and the rotor. (4)
- Again clamp vibrator head housing (6) in vice and
unscrew hose holder (11). (Left Hand Thread)
- Remove rear flange (7) (tap on wooden block again if
necessary), cut hose clamp (9) & remove inlet hose (13)
from flange nipple. (8)
- Unscrew the hose retain sleeve (10) & remove exhaust
hose (12). Also remove spring (See Optional Parts List)
from this hose only when it is provided.
- Cut hose clamp (14) on the outer end cap (17) and
remove exhaust hose. (12)
VARIABLE CONTROL ASSEMBLY:
- Unscrew the outer end cap (17) (Right Hand Thread).
Cut hose clamp (9) & remove inlet hose. (13)
- Remove screw from bushing. Remove body from bushing.
(Tap on a wooden block if necessary).
Note: Make use of the maintenance kits (See Page 3)
