3. STARTING THE ENGINE
Check oil level.
Turn fuel tap on.
Put speed control lever to tick-over.
If engine is cold, close the choke (petrol engines only).
Turn engine switch to ON(1) position.
Pull the starter rope toggle lightly until resistance is felt, then pull briskly using quick
short pull. Do not pull rope to its full extent or allow toggle to snap back against
engine. Return it gently to avoid damage.
When engine is warm open choke.
Position engine speed control lever to give required engine speed (usually full
speed).
Commence vibration - the compactor is self-travelling.
To stop engine, position the engine speed control to slow and turn the engine switch
to off(0).
Turn the fuel valve to off.
4. OPERATOR INSTRUCTIONS
Read section (1) - Safety.
NOTE: Drive between engine and vibrator is through a centrifugal clutch. Vibration
will commence as engine speed is increased.
Position the engine speed control lever to give required speed (usually full speed).
Commence compaction. The compactor is self travelling. Its speed of travel and the
number of passes required to achieve optimum compaction depends on the type and
condition of material being compacted and the layer depth.
Uniformly graded granular material compacts far more efficiently than wet cohesive
material.
When compacting block paving always use a rubber attachment mat, contact your
agent for details.
When compacting blacktop always use a water spray, contact your agent for details.

Do not run the machine on solid concrete surfaces, as this is likely to cause damage.
5. GENERAL MAINTENANCE
Top up engine oil daily and change regularly using the correct grade of oil in
accordance with the engine manufacturers instructions. If the machine is working
continuously, check the oil level and top up twice daily.
Clean the air filter element regularly. In very dry, dusty conditions, this should be
done daily.
Lightly oil the wheel spindles and wheel arm spindles monthly.
Check tightness of all nuts and bolts monthly.
6. ENGINE
Removal
Unfasten screws (19) and remove the guard (20) and the vee belt (16). Remove the
engine mounting bolts (21) and nuts and lift off engine. For engine service, refer to
the manufacturer’s instructions.
Replacement
To refit engine, reverse removal instructions. Set engine speed to 3300 r.p.m.
7. VEE BELT ADJUSTMENT
Unfasten screws (19), remove the guard and check belt tension. It is important to
note that belt tension in this application is much less than is generally accepted as
normal. Too high a belt tension may lead to engine damage due to excessive
transmission of vibration from the power pack through the vee belt.
To adjust belt tension, loosen the engine mounting nuts and screws (21) and move
the engine backwards towards the handle until the front of the engine mounting plate
moves downwards slightly. Adjust the engine position to allow the mounting plate to
just return to normal level position and tighten the engine mounting nuts and screws
after making a final check that the clutch pulley is in line with the bottom pulley.
8. CENTRIFUGAL CLUTCH
8.1. M TYPE CLUTCH
Removal
Remove the guard and vee belt.

Remove the four bolts (15) and nuts which hold the clutch assembly together. Warm
the front cover bearing housing (14) and tap the back of the vee belt pulley to
withdraw the pulley and front cover. The clutch shoes and inside face of the pulley
can now be inspected. If no further work is required, reassemble in reverse order.
To further dismantle remove the outer bearing (6) and spacer (13) using a suitable
extractor.
To remove the clutch, release the locking tab from the taper lock nut (17) and remove
the nut and lock washer. Use a suitable extractor to pull the clutch off the taper lock
sleeve. If both the clutch and taper lock sleeve move together, continue to pull until
they have moved about 3mm along the shaft adaptor. Now remove pulley extractor
and screw on taper lock nut for about 3 turns. Place a short length of tube over the
end of the shaft so that the end of the tube bears against the taper lock nut. Give the
tube a sharp tap with a hammer to release the taper lock. The taper lock and clutch
can now be easily withdrawn.
Lever out key (1), unscrew the countersunk screw (4) and withdraw the shaft
adaptor. If the shaft adaptor is screwed onto a threaded shaft, grip the large
diameter with "Mole" grips and unscrew (right hand thread).
Replacement
Re-assemble in reverse order. To position the pulley assembly and clutch correctly,
fit the distance ring (7) against the shoulder on the shaft adaptor with the recessed
side facing outwards. The taper sleeve butts up against the distance ring.
8.2. B TYPE CLUTCH
Removal
To remove the clutch from an engine with a 3/4" keywayed shaft unscrew screw (33),
withdraw spacer (29) and pull clutch assembly off shaft.
To remove clutch from an engine with a 5/8" unf shaft unscrew nut (34), remove
washer (35) and withdraw clutch assembly. It is possible that when nut (34) is
unscrewed shaft adaptor (37) will unscrew from the engine shaft rather than the nut
unscrewing from the adaptor. If this happens remove entire assembly, grip the
shoulder end of the adaptor in a vice suitably supported internally with a short length
of 5/8" bar inserted into the end of the adaptor and unscrew nut (34) as above.
To dismantle the clutch remove circlips (27) and (28) and press out hub(24) complete
with shoes and springs.
If it is necessary to remove the shoes and springs note first the orientation of the
shoes in the hub and which notch is located on the hub. Care also should be taken
when removing the springs.

Replacement
Replacement is the reverse of the above procedure but ensure the shoes are
replaced to the same orientation as the ones removed.
9. ENGINE MOUNTING PLATE AND ANTI-VIBRATION MOUNTS
Removal
Unscrew screws (27) and lift off the engine plate. The anti-vibration mounts can now
be removed after unscrewing nuts (63).
Replacement
Inspect anti-vibration mounts for deterioration, cracking, tearing etc. and renew if
necessary.
Refit anti-vibration mounts to brackets on base plate ensuring a star washer is
between the mount and the bracket and that there is also one under the nut. Do not
tighten the nuts at this stage.
Refit engine base plate fully tightening screws (27) remembering to place star
washers under head of screws. If a mount tends to twist when screw (27) is
tightened, ensure nut (63) is loose.
Finally, tighten nuts (63).
10. HANDLE, BRACKETS AND ANTI-VIBRATION MOUNTS
To remove handle, unscrew special screws (47). The handle can now be lifted clear.
When re-fitting the handle, ensure that star washers are placed between the handle
and the anti-vibration mount to prevent the mount from twisting when the special
screws (47) are tightened.
Dismantling of the brackets is straight forward, but take care not to over tighten the
locking lever bolt (43) when reassembling.
11. WHEEL ARM ASSEMBLY
Dismantling and reassembly of the wheel arm is straightforward. However, prior to
reassembly it is worthwhile applying a thin coating of graphite grease to the wheel
arm pivot and to the wheel axle. It should be noted that the dished side of disc spring
(48) faces the wheel arm.

Dismantling
Remove brackets (38).
To remove the pulley (32) release the locking tab of the taper lock nut (31) and
unscrew the locknut approximately two turns. Place supporting wedges between the
pulley and the vibrator case end plate (30). Position a short length of tube over the
end of the shaft so that it bears against the taperlock nut. Give the tube a sharp tap
with a hammer to release the taper lock and remove pulley and taper lock from shaft.
Unscrew the cap head screws retaining the end plate and remove the end plates.
If it is felt that the bearings are not worn, but need regreasing, use Castrol BM2 or an
equivalent grease. Half fill the bearings and fully fill the end caps. If the bearings are
to be renewed, continue dismantling as follows.
Strike the long end of the vibrator spindle with a copper faced mallet. This will drive
out the vibrator spindle and far bearing. Remove the near bearing by striking it with a
suitable drift inserted from the far end.
Reassembly
Grease the bearings as described above
First place a bearing shield (64) over the short end of the vibrator spindle with
grooved side facing outwards and then press on a bearing. Apply a thin layer of
grease to the outside of the bearing and to the bearing housing. Offer the bearing,
spindle and bearing shield to the housing and force home using copper faced mallet
or press. Fasten the rear cover (36) into position using cap head screws (33)
Place a bearing shield over the end of the shaft. Lightly grease the inner and outer
surfaces of the second bearing and also the shaft and housing. Force the bearing
onto the shaft and into the housing using a suitable tubular drift and copper faced
mallet. Renew the seal in the end plate and refit end plate.
NOTE: Some older base plates might not have a shoulder in the bearing housing.
For these applications only Nilos ring, Part No. W81053 may be used. These fit on
the shaft between shoulder and bearing. If they are not available, pre lubricated
bearings; Part No. W81020 with shields may be fitted. For housings that do have a
shoulder, bearing shield, Part No. W51788 should be used.
Replace the bottom pulley and taper lock, but do not tighten until the engine is in
position and pulley adjustment can be checked.
