Important Safety Notes
Please Read Carefully.
1. As a new owner / operator of a Dromone ‘MULTI-LOCK Quick Coupler’ it is
very important that you take time to acquaint yourself with the main features of
the hitch and the requirements for its
safe operation and maintenance.
Therefore, we recommend that you
study the contents of this booklet very
carefully and be fully familiar with its
contents before commencing work.
Always treat couplers with the respect
they deserve.
2. Great care must be taken when working on or with the ‘MULTI-LOCK Quick
Coupler’. Never attempt to work on, or
carry out maintenance to this product
without first ensuring that it has been
made safe, and that the machine to
which it is attached is switched off.
3. In the case of a hydraulically operated
hitch. Even with the machine switched
off the hydraulic circuits may remain
pressurised so care must be taken when
connecting / disconnecting hydraulic
hoses.
4. While the ‘MULTI-LOCK Quick Coupler’ is designed and proven to work with
most available buckets and other attachments. Dromone do not approve the use
of mechanical pulverises, mechanical
shears, mechanical stump grinders and
such tools with this coupler. Limited use
of breakers with the coupler is permitted.
Warranty will be void if such attachments
are used with this coupler.
5. Regardless of the bucket or attachment being used with the ‘MULTI-LOCK
Quick Coupler’ they must be used in
strict accordance with their individual
manufacturers guide lines and instructions.
6. In order to ensure that you get the
most from your ‘MULTI-LOCK Quick Coupler’ product we have set out in this
booklet some recommended service and
maintenance checks. These should be
carried out on a regular basis and any
damaged parts should be replaced immediately.
7. Never attempt to modify either the
Dromone Multi Lock Quick Coupler or the
machinery onto which it is intended to be
attached without first receiving approval
from Dromone Engineering personnel.
Unauthorised modification of the Quick
Coupler or the host machine can seriously impair the performance of the
equipment and could cause serious injury
to personnel.
8. It is the responsibility of all persons
involved in the installation, maintenance
and operation of the Dromone Quick
Coupler to ensure their own personal
safety by wearing suitable protective
clothing, safety footwear, Hi-visibility
vests and ear & eye protection where appropriate.
9. If you should have any difficulty with
your Dromone Multi Lock Quick Coupler
which is not addressed in this manual,
then you should contact Dromone Engineering Ltd. Immediately at the numbers
provided on the back of this manual.
10. Although every effort has been made
to optimise the strength and durability of
the Dromone Multi Lock Quick Coupler, it
should be noted that the typical environ-
QMS 22 Dromone Multi– Lock Quick Coupler Author:EOD
REV: D - JAN2012 5 Approved:MS
Page 6
Dromone Multi– Lock Quick Coupler
ment in which the coupler is likely to be
working can be extremely harsh and detrimental to all types of machinery. For this
reason, Dromone Engineering highly
recommends that; as well as the regular
maintenance checks, certain components
be replaced as a matter of course after
reaching a pre-specified no. of working
hours.
Intermittent problems can be symptoms
of imminent failure and if these are experienced with key control components
such as the control box or solenoid valve,
these components should be replaced immediately.
Details of specific components and their
expected normal working life can be
found in the Maintenance section of this
manual. Please take the time to become
acquainted with these components and to
monitor their working age.
Only genuine Dromone parts must
be used to service this Quick Coupler.
Dromone Engineering Ltd. reserves
the right to waive liability if non
genuine parts are fitted to this Coupler.
11. It is important to note that if you or
your representative is responsible for the
initial installation of the Dromone Quick
coupler, especially in regard to the hydraulic / electrical system; you must take
the full responsibility to make sure the
installation is carried out in strict accordance with Dromone Engineering’s instructions. Any failure to do so may allow
the unsafe operation of the coupler and
result in serious injury or death, with the
installer being found to be liable.
12. Other than the structural integrity of
the Dromone Multi Lock Quick Coupler,
the most important component(s) in this
coupler are the two hydraulic cylinders
and the front and rear pin locking mechanisms.
It is imperative that to ensure the continued safe and effective use of this coupler,
a daily check be carried out to monitor
wear, blockages and other damage that
can possibly occur to the detriment of the
system’s safe operation.
While every effort has been made by Dromone Engineering Ltd. To provide a safe,
durable and effective product to work in a
typically harsh environment, it must be
stressed that it is the responsibility of the
owner / user to keep the system serviced
and in good working order. The machine
operator and / or owner could be held to
be negligent if they either fail to keep the
system in good order.
13. It is essential to ensure continued
safe operation of the Dromone Multi Lock
Quick Coupler, that along with regular
maintenance checks and services carried
out on the coupler; close attention be
paid to the presence and condition
(legibility) of all the decals in the machine’s cab.
If one or more of these decals become
damaged or lost, it is essential that they
be replaced immediately. Dromone Engineering has supplied an extra set of decals with this manual for this eventuality.
If you have not received these decals you
should contact your dealer immediately. If
you have further need for decals, you can
contact Dromone directly at the address /
Tel no. printed in this manual.

14. Lifting eye can only be used with the
machine if there is a hose burst check
valve on the boom. It is the responsibility
of the fitter to disable the lifting eye, if
the safety check valves are not incorporated
If the coupler is fitted with a lift eye,
please inspect daily before use for wear,
cracks and fatigue. If damaged do not
use.
Always use approved lifting shackle and
chains in conjunction with the lift eye.
Check the SWL (Safe Working Load) that
is stamped on the coupler and ensure
the lifting equipment is compatible.
Always check the excavator manual for
the machine SWL as this determines the
lifting capacity of the machine. This SWL
should never be exceeded under any
circumstance.
Always remove the attachment on the
coupler prior to using the lift eye.
No other part of the coupler may be used
for lifting other than the lift eye.
The lift eye on the coupler has been
tested and stamped by Dromone, this
test is valid for 12 months from first date
of purchase, there after it is the responsibility of the machine owner to insure the
lift eye remains compliant to each countries national standard.
15. The quick hitch should only be fitted
to the machine referred to on the Serial
number plate or the declaration of incor-
poration. Should the model on the badge
be different on the badge, permission
should be sought from Dromone engineering before commencing fit-up.
16. Sequence of Operation of the
Dromone ‘Multi Lock’ Automatic Coupler:
Opening:
•
Rear Lock Hydraulically Opens
•

18. The working range of the machine
can change with the incorporation of a
quick hitch. This includes the following:
•
The bucket is more liable to interfere with the dipper arm and possibly the cab in which can lead to injury or death (
Figure 2
).
Fig 2. Possible interference
QMS 22 Dromone Multi– Lock Quick Coupler Author:EOD
REV: D - JAN2012 7 Approved:MS
Page 8
Dromone Multi– Lock Quick Coupler
•
Break out force is reduced at the
tip of the bucket due to the longer
distance from the pivoting area.
•
As can be seeing from
figure 2
above this is ideally the danger
zone and it follows a 360 degree
axis to the machine from the centreline of swing. As well as this, the
working radius of the machine increases due to the extra distance
between the bucket and the dipper
arm.
•
Maximum operating capacity is limited with the use of quick coupler.
Refer to excavator owners manual
for further information on max operating loads.
20. Please note that under no circumstance, does Dromone engineering authorize the transport of people with a
quick hitch, even if the quick hitch is designed to do so.
