Instruction manual
Light, powerful and fast, modec PVAs (Portable Valve Actuators) offer improved safety and comfort for operators
and protect equipment from damage. They can be adapted to all types of handwheels, keys and valves, and have
a torque range that can reach up to 1000Nm.
They can be powered by various energy sources. What’s more, they come with a large number of options, adaptors
and accessories so they can be specified to exactly match the requirements of all clients and all applications.
modec gas portable valve actuators can be used in total autonomy –the only limit being the available petrol
supply. They are particularly suitable for use in isolated outdoor places. Extremely robust, they have an integrated
clutch system that protects the operator and the equipment, even if a valve is completely blocked.

Work zone safety
Keep the work area clean and well-lit –minimum level lighting of 300 lux
Aside from the operator, keep any other people at a safe distance within a radius that takes account of fixed points,
straps, chains and any other torque retention system used.
To protect the operator, we recommend that you do not use the PVAs if there is a risk of lightning.
Safety of personnel during use and maintenance
Stay vigilant –watch what you are doing and apply common sense when using the tool. Do not use a tool if you are tired
or under the influence of drugs, alcohol or medicines.
Use the individual safety protection equipment (see the summary table, page 7).
Do not rush ahead –maintain a suitable position and balance at all times.
Wear suitable clothing –do not wear baggy clothes or jewelry. It is obligatory to tie back hair and to wear close-fitting
clothes (not floaty) to ensure all clothing parts are distanced when moving.
To avoid the motor starting at the wrong time, before picking up or while carrying the PVA, place the cursor in the 0
position. Even better, disconnect the spark plug
Use and servicing
Do not use the tool if the switch systems for changing direction, accelerating, starting up or stopping are not working
properly. This could pose danger to the operator.
Observe tool maintenance. Check there if no incorrect alignment or blockage of moving parts or from broken parts or any
other problem that could affect how the tool functions. If there is any damage, take the necessary steps and precautions
to return the tool and its accessories to good working order.
Have the tool serviced by a qualified repairer using only modec products when changing parts.
Only use valve accessories recommended and approved by modec. Think to consult the accessory list provided and/or
seek advice from modec for specific uses.
Before starting up the motor, the operator must, without fail, check the follow points:
-Accessories mounted or activated by the actuator are in good condition and correctly attached.
-The most suitable torque retention system is being used and it assures the safety of the operator.
-The system that fixes to the valve or the handwheel is adapted to the valve or handwheel being actuated.
-Both the actuator and the operator are in a stable position. The operator is placed in opposition to any possible
movements the actuator may make while coming to a stop.
Stop the actuator immediately if it starts to behave differently (a change of noise, increased vibrations). Replace all
damaged parts of the actuator and accessories. Damaged parts can burst and cause serious harm, even a potential
fatality.
Before placing a handwheel on, or removing it from, the actuator, wait until the actuator has come to a complete stop.
Only activate the command to inverse the direction left/right when the actuator is fully stopped, otherwise the operator
may find they are working in a poorly adapted position.
Always hold down the rotation direction switch until it stops.
In certain circumstances, the tool may keep rotating for several seconds after releasing the switch. Never put your hands
close to the tool or any moving parts.

5. Starting up the Portable Valve Actuator
a. Filling the fuel tank
Pressure can increase in containers holding petrol, due to the ambient temperature. Open the petrol cap carefully
to avoid any projection. Leave the fuel in a cool place, for short periods and never leave it in the sun.
PRECAUTION
Clean the fuel tank cap and its surrounds to
prevent any foreign bodies entering the tank.
Fill the fuel tank using an appropriate-sized
funnel or from a can with a special pouring
head.
For greater convenience, place the machine in
the operating position.
Make sure the apparatus is stable while carrying
out this procedure so it doesn’t topple over.

b. Before starting up
Check the protection casings are in place, correctly tightened and are not showing any defects (cracks).
Check that any accessories are attached correctly and firmly, check the condition of the handles and switches as well
as the petrol and oil tank caps.
Move the machine away from where the fuel was added.
Place the actuator flat on the ground close the device that it will actuate.
Make sure that the spark plug hood is in place.
GENERAL PRECAUTION :
Make sure the “STOP-0 I START” button is in the stop position (0) and never start the actuator directly coupled to a
handwheel or valve.
If this precaution is not taken, the actuator risks being set in motion when the motor starts (despite the clutch) and
could cause bodily harm.
The petrol gas actuator PY68 can run in any position but must be started up horizontaly so that lubrication is correct.
COLD START
The actuator is considered “cold” if the motor has not been turned over prior to starting.
NOTE: If the ambient temperature is quite hot (in summer), it may be that the motor starts better without a choke.
START UP AS FOLLOWS:
1. Move the choke lever (3) in the up position (closed). 2. Press several times on the priming bulb [4],
located under the carburetor, to draw in the petrol.
For these points, consult the user manual of the
Honda GX35 motor

cursor into the START position.
5. When the motor has started, move back the choke lever [6] in the down position.
PRECAUTION :
•Don’t pull the starter grip to its full extent.
•Do not allow the starter grip to snap back against the actuator. Return it gently to prevent damage to the starter.
NOTE : Always pull the starter grip vigorously. If you don’t, the spark plug won’t produce the sparks needed to start the
motor. Don’t place a foot or knee on the transmissions tube to stabilise the machine – you could twist it and make the
machine unusable.
HOT START
The actuator is considered as « hot » if it has ran over more than 5 minutes in the past 10 minutes. The procedure for starting
from hot is identical to that of starting from cold except that there is no need to use the choke that should remain in the down
position [6].
NOTE: In case of difficulty starting the motor from hot, use the following procedure:
1. Turn the actuator switch « STOP-0 ISTART » to the “STOP-0” position.
2. Move the choke lever down to the “open” position.
3. Hold the throttle lever in the max speed position.
4. Pull the starter grip 3 to 5 times.
5. Start the actuator following the procedure described above.
STOPPING THE ACTUATOR
1. To stop the engine, simply push the actuator switch « STOP-0 ISTART » to the “STOP-0” position
2. This is also the way to stop the actuator in case of emergency.
Please note that the actuator can carry on turning by inertia after stopping the motor.

6. Setting up the Portable Valve Actuator
a. General info
The actuator must be kept stable while turning the valve or handwheel.
modec Portable Valve Actuators can be used in any position.
However, to ensure the operator is working safely and in the best conditions, it is imperative that the actuator is used in
the axis of the handwheel being activated.
NB: These diagrams are made with one of the modec actuators. However, the head (flange and output shaft) being identical
on all actuators, they apply in the same way to all the actuators of the range.
b. Fixing the actuator on to the torque management device and/or on an adaptor
To ensure the operator is working safely and in optimum conditions, it is imperative to use a torque retention system.
Our actuators are delivered with:
A BR001 torque management reaction bar
A strap or a chain
2 carabiners.
In addition to this basic pack, modec also has a
wide range of torque management accessories
(see the catalogue and the following presentation
for more details).
As well as these standard accessories, modec
develops specific systems. If you would like to
check your installation or if you have a specific
solution request, contact a registered modec
distributor.
Besides this torque retention rod, it is also
possible using the “modec standard” flange and
shaft to fix the system to RA30 right-angled
models, to BJH hollow heads and all modec
torque management accessories (see
catalogue).
If the standard equipment does not provide a
torque retention that offers sufficient safety for
both operators and equipment, modec can
develop and/or adapt special torque
management systems.
Never use a portable actuator with a torque management system that is under-sized, unstable or badly
positioned.

Place the black ring of the torque management bar on the flange so that the 6 pins enter the corresponding holes.
Make a quarter turn with the fixation springs rings and release the springs making sure they come back.
Check that the torque management bar is properly secured to the flange.

7. Using the actuator
a. Preliminary checks
1–Check the equipment is in good condition and use accessories that are the most suitable for the actuator.
Make sure the torque management system and the handwheel adapter are compatible with the action about to be
carried out.
2–Start the petrol gas motor and leave it to run slowly.
3–If the actuator has a torque limiter, set it to minimum.
4 –Check the rotational direction required for the valve, indicated on the handwheel or the manual. Set the defined
rotational direction using the actuator’s left/right switch.
5 –Position the adaptor on the valve and set up the torque retention system. Consult the instructions for adaptors.
6 –Check the operator is correctly positioned in relation to both the actuator and the torque retention rod. When used, the
actuator (or the torque retention rod) is designed to have a tendency to move away from the operator. This way, if there is a
malfunction, the operator drops the tool safely and it will then move away from him and immediately stop.

6 –When starting up always start up slowly in order to VERIFY the rotational direction, and to put tension on the torque
retention strap or chain.
Switch on to (Start) Lock the safety trigger Accelerate slowly
Once started, let the motor run slowly
The apparatus is equipped with a clutch. When accelerating, the motor runs before engaging the gearbox and output. This
shift process is normal.

b. Potential problems when actuating a valve
1 –If the valve doesn’t move, release the handle and change the actuator’s rotational direction to give it a little nudge.
Check again the direction of the torque retention.
2 –If there is increased resistance from the valve (torque applied to the actuator), the actuator will slow down until the
clutch will slip. At this moment, the motor will run but the output shaft will not. Release the throttle.
3 –Be very careful that the applied torque does not exceed the limits the valve can withstand, or use a torque limiter
(optional).
4 –In case of resistance resulting from deposits on the stem, turn the valve in both directions several times to ‘clean’ it.
modec revolution counter (optional) enables you to always know which position the valve is in.
5 –When the closed position is reached, make sure the torque does not exceed the level that the valve can withstand.
Unless the procedure indicates otherwise, reopen the valve with a few turns so that the accelerated fluid “cleans” any
potential impurities from the valve, then close it again at the desired torque.
6 –When the maximum open position is reached, reclose with a few turns to avoid the valve being stuck in future. Doing
this also means that the valve is still able to turn when next actuated even if the operator turns it the wrong way, which again
helps prevent the valve being stuck.
Take note - the torque when closing a valve should always be inferior to the torque when opening a valve, in order
to guarantee that the valve can be reopened. Using a torque limiter for closing and opening a valve means you can
be always be sure to have enough torque in reserve for the valve to be reopened or reclosed.

Instruction notice (EN)

8. Options
a. Digital Revolution counter
PRESENTATION
The digital Revolution counter adds up the
revolutions in one direction and subtracts
them in the other direction in such a way that
the operator always knows where he is in
relation to the initial set-up. The tool also
measures and shows the rotational speed.
Nota 1 : The instant speed indicator needs several revolutions before it can give a stable and regular speed. In light of this,
you have to wait several seconds to get a reliable reading.
Nota 2 : The screen turns itself off after 5 minutes.
HOW IT WORKS
« Revolution count mode ‘’t’’ » « Speed mode ‘’s’’ »
3 s
« Reset to zero »
REVOLUTION COUNTER PARAMETERS
The revolution counter is set by default for a straight or right angle head standard output shaft (STD), without Banjo head.
When used with a BJH banjo head (see chapter 8), the number of turns and the output speed of the actuator will be
different, so you need to select “BJH01” for a standard duty Banjo head (speed is divided by 4) or “BJH02” for a heavy
duty Banjo head (speed is divided by 3).
If you want to set a specific ratio for speed and count,
select “SP”, then indicate of you want to multiply (“M”)
or divide (“d”) the speed and number of turn,
and set the ratio “I=” from 1.0 to 20.0.

CHANGING THE BATTERY
b. Torque limiter
The modec torque limiter allows setting the actuator maximum torque within a certain range
1 –Thumb wheel : to block the adjustment ring in the chosen position
2 –Adjustment ring : Allows setting the maximum torque value.
« + » –Direction to increase torque limit
« - » –Direction to decrease torque limit
3 –Reloading ring : to reload the torque limiter after it stops.
HOW IT WORKS
1. Set the maximum torque value to the desired level:
-Loosen the thumb wheel (1)
-Move the adjustment ring (2)
-Tighten the thumb wheel (1)
2. Check the torque limiter is engaged by pushing the reloading ring (3) towards the front of the actuator.
3. Use the actuator until the torque limiter is released.
4. Re-engage the limiter by pushing the ring (3) towards the front of the actuator.
This procedure can only be carried out if the motor is stopped (or, for the petrol gas actuator, if the motor is
running slowly with the clutch not engaged).
In order to avoid any untimely disengagement, make sure that you start the actuator gradually, and smoothly.

General recommendations
Take note of all the work health and safety regulatory provisions that apply and any local workplace safety instructions including
conditions relating to the work environment, clothing and the operator’s individual protective equipment as required by all the
applicable regulations.
It is advisable to keep a maintenance log for all maintenance tasks carried out on the actuator.
Prevent foreign bodies from entering the system by using a clean work surface in order to protect the delicate moving parts from
being contaminated by dirt or foreign materials when assembling and dissembling, as this could cause a deterioration of the
mechanical parts.
Maintenance of the Portable Valve Actuators should be carried out by people who have been trained by modec.
Our “After Sales Service” department are ready to help in this respect.
Systematically take out the spark plug before carrying out any procedure that involves replacing, adjusting, servicing or
dissembling the actuator or any of its parts.
Every time maintenance is carried out, test the actuator afterwards to check it is working correctly.
Only use approved replacement parts and follow the manufacturer’s advice with regard to lubrication and waterproofing.
