IMPORTANT NOTICE
Vibrators and vibrating equipment can be dangerous if not used correctly.
1. DO NOT hold steel vibrating heads when running.
2. DO NOT stand or sit on vibratory equipment when running.
3. USE ONLY for the purpose intended.
4. USE ONLY when pneumatic hoses and fittings are securely tightened.
5. ALWAYS wear ear protectors.
General Safety
For your personal protection and safety of others around you on site, please read and ensure you fully understand the following safety information. It is the responsibility of the operator to fully understand how to operate
this equipment safely. If you are not sure consult your supervisor.
Points to remember are:
1. Keep unauthorised personnel at a safe distance from the work area.
2. Personal Protective Equipment (PPE) must be worn by the operator whenever this equipment is being
used, i.e. Safety goggles, gloves, ear defenders, dust mask and steel toe capped footwear. Always protect skin from contact with concrete.
3. Ensure that the compressor does not exceed 90 psi.
4. Never dismantle or tamper with any seals or covers fitted. Always check the vibrator thoroughly before
use for condition and safety. If any parts are damaged or missing do not use the vibrator until it is repaired or replaced.
5. The air supply must be switched off before any work is carried out on the vibrator. To prevent accidental
starting of the vibrator, it must be disconnected from the air supply.
6. The vibrator should never be left running out of concrete as it will become extremely hot and internal parts
will be damaged. Caution must be exercised when touching the vibrator head.
7. When the vibrator is not used for long periods of time, store it in a clean, dry and protected environment.
It must be hung up with the head upwards and the control handle open to allow moisture etc. to escape
from the vibrator.
8. Some vibration from vibrator is transmitted through the flexible hose to the operator’s hands. The hose
should not be held within 1 metre from the head of the vibrator at any time. Operational exposure time
may need limiting if fingers become effected.
9. Do not operate the vibrator when you are feeling unwell, tired or when under the influence of alcohol or
drugs.

ATTENTION Never use a high pressure compressor.

General Maintenance
1. Vibrators are delivered without lubrication. Ensure to add oil before starting the vibrator.
2. Before connecting the vibrator, ensure the air line is clean from any water or dirt it may contain.
3. Refill lubricator after every four hours of use with 20/30 S.E.A. non-detergent oil.
4. To start the vibrator it may be necessary to tap the vibrator’s hardened nosepiece onto a firm surface.
5. After use, hang the vibrator with the head upwards and leave the control handle open to drain out of any
water or dirt.
Dismantling and Re-assembly Instructions
1. Replacement of Vane and Rotor
Hold housing (4) in a vice and unscrew nosepiece (1A) - right-hand thread. Remove from the vice and by
angling downwards the rotor is free to drop into the hand ensuring not to cause damage. The parts should
be cleaned and examined . If the nosepiece shows signs of excessive wear, then it should be replaced (see
point 4). Vanes must be a snug sliding fit in the rotor and fitted so that the vane cuts-out face away from the
milled slot in the rotor. Adjust length of vane to 0.1 - 0.15mm shorter than the rotor.
Re-assembly is opposite to the above, but the following should be observed:
1. Lightly oil running faces of the rotor.
2. Insert rotor so that the exhaust holes are in opposite end to the nosepiece.
3. Fit a new ‘O’ ring or fibre washer (2) onto the nosepiece (1A).
Note
Some models (V665-V6105) have nosepieces (1) and separate front closure plates (3). Dismantling is similar
to the above and these two parts are available as spares.
2. Removal of Rear Body, Rear Closure Plate and Hoses
Cut exhaust hose clip (16), pull off exhaust hose (15) from exhaust body (17). Unscrew exhaust body (17)
from lubricator/handle (39/30), then pull out handle to expose hose clip (10). Cut hose clip (10) to release inlet
hose (11) from the handle. Hold housing (4) in a vice and unscrew rear body (12) - left-hand thread, removing
complete with exhaust hose (15). If the hose is to be replaced then unscrew hose sleeve (13), pull out hose
(15) from rear body (12) and remove hose protection spring (14) - only on models V675 - V6105. Using inlet
hose (11) pull out rear closure plate (7), locking ring (8) and inlet hose connector (9). All parts should be
cleaned and the rear closure plate (7) examined for signs of wear (see point 4).
3. Re-assembly
Rear closure plate (7), inlet hose fitting (9) and inlet hose (11) should be inserted into the housing as an assembly, ensuring that the plate is kept square to the housing (4) and pushed onto the housing shoulder. Slide
new locking ring (8) over inlet hose (11) and locate behind rear closure plate (7). If necessary, fix exhaust
hose (15) into rear body (12), insert hose protection spring (14) - only models V675 - V6105, and clamp with
hose sleeve (13). The assembly can then be screwed onto the housing (4) ensuring that a new ‘O’ ring or
fibre washer (2) is fitted. Adjust hose lengths so that the inlet hose (11) protrudes approximately 65mm from
the exhaust hose (15). Slide new clips (10 & 16) onto respective hoses (11 & 15). Pass inlet hose (11)
through exhaust body (17) and fit onto inlet hose connector (18) using hose clip (10). Screw exhaust body
(17) onto control handle (30). Push exhaust hose (15) onto exhaust body (17) and fit hose clip (16).
4. Wear Criterion
The optimum condition of the vibrator turbine assembly to produce maximum speed and therefore power is
determined by the total air gap of the rotor. Ideally this should be between 0.06 - 0.13mm and a total gap
greater than 0.20mm greatly impairs the performance. The length of the rotor is 129.00 - 129.02mm when
assembled at the factory and if worn below 128.70mm, it should be replaced.
