electrically insulated.
Do be aware that this tool can
create flying debris.
Do be aware of others working
around you.
Do store this tool in a secure and
dry place.
Always observe safe working
practices and local safety
reg lations at all times.
Never aim the Hydraflex hold

Do not operate the Hydraflex,
unless it is securely fixed to its
tripod and situated on a flat
surface.
Do not modify this tool in any way,
as this will invalidate the warranty

Please note: Unrestrained air and
water hoses can whip if they
become detached.
Water S pply
Ensure that a minimum 51mm
(2.0”) bore water hose is used and
that all couplings are secure, leak
free and in good condition.
The recommended water
press re is 5.9 bar (85p.s.i.).
Air S pply
Ensure that a minimum 19mm (3/4”)
bore air hose is used and that all
couplings are secure, leak free and
in good condition.
Limit the length of air hose to 30M
(100ft). Where extra length is
necessary, for each additional 15M
(50ft) of air hose used, the pressure
drop is approximately 0.21bar
(3psi).
Recommended air press re is
6.9bar (100 psi).
Do not let the operating pressure fall
below 6.2bar (90p.s.i.) or rise above
7.6bar (110 psi)
Preferably, the compressor should
be able to supply a minimum of 47.2
L/s (100cfm) free air.
Starting Work
Prior to operating the tool check: -
That all fittings are secure, free from
leaks and air hoses are in good
condition.
That the air press re is correct for
this tool 6.9 bar (100 psi).
That the water press re is correct
for this tool 5.9 bar (85psi).
Safe use of this tool requires that the
operator adopt a solid stance and
secure foothold.
Gloves and personal protective
equipment m st be worn when
using this tool.
Care must be taken to avoid
damaging or tripping over the air or

Erect the tripod and spread the
tripods legs fully, ensure that the
tripod is placed in a stable position.
Remove the safety pin from the
swivel pin and remove the swivel pin
from the tripod, attach the Hydraflex
to the tripod securing it with the
swivel pin, replace the safety pin.

OPERATION
Pre-Start Check
Always clear the air hose before
connecting it to the Hydraflex, this
is to ensure the removal of any
foreign bodies that may be
present, which would otherwise
block, or choke the valve
assembly.
Connect a 51mm (2.0”) water hose
to the rear of the Hydraflex using
the hose adapter or fit one of the
supplied instantaneous couplings
to the hose and connect to the
adapter.
IMPORTANT: Take precautions to
ensure that the area to be cleaned
is completely free of personnel and
of any electrical equipment that is
exposed or is not protected against
water ingress (IP67 minimum
protection).
Machine Operation
With one operator securely holding
and controlling the Hydraflex a
second person should slowly open
the water valve at the main or pump.
It is very important that the Hydraflex
be held securely while the water is
being turned on and while it is in
use.
The air valve should now be
adjusted carefully to produce a tight
hard-hitting jet of water. Excessive
air will cause the jet of water to
break up and spread, becoming less
effective.
In an emergency or once cleaning
has been completed, close the air
valve and instruct the second
operator to shut off the water supply.
Disconnect the air and water
hoses and wipe all deposits from
the outside of the Hydraflex.
Remove the safety pin and then
taking the weight of the Hydraflex,
remove the swivel pin from the
tripod and remove the Hydraflex.
Replace the tripod swivel pin and
replace its safety pin.
When collapsing the tripod, take
care not to trap fingers or hands.
It is recommended that the joints
and swivel head of the Tripod be
lubricated prior to storage.
Cover the Hydraflex hold cleaner
to protect it and store in a secure
and dry place.
