FLIGHT SAFETY PRECAUTIONS
•The Parajet Volution XT 180 Aero engine has been run-in prior to shipment. This
means that your Volution is ready to fly. It is important however that excessive
throttle is NOT used for at least the first 10 hours of flying. For example, do NOT
depress the throttle fully for more than 30 seconds at a time. A well run in engine
will outperform an engine that has been run at full power for long periods right from
the start. You can potentially damage a new engine with excessive throttle.
•The Volution Paramotor unit is to be used only after having received ade uate and
proper training from a ualified motor paragliding instructor.
•Max weight capacities for paramotor pilots flying a Parajet Volution range
paramotor:
Parajet Volution Model Max Pilot Weight
Micro
80Kg
Compact
100Kg
Macro 160Kg
•The Volution should only be used with canopies designed for motor paragliding.
•Always conduct a check of all components before every flight.
•Always wear a helmet, flight shoes and gloves when flying the Volution.
•Always stay clear of moving parts such as propellers, pulleys and belt.
•Always stay clear of hot engine parts and muffler.
•Do not fly low le el o er water, woodland, or potentially hazardous landing
areas. Do not fly into controlled airspace or o er built up areas, it essential
always to consider a safe landing area should you experience an engine failure
or loss of power.
•Before starting the engine check the area is clear and shout “CLEAR PROP”
•Always ensure that the power unit is switched off when not in use. The main power
switch is to be found on the left side of the machine just behind the harness.

SOME GOLDEN RULES !!!
1. Never place your engine downwind of your wing.
2. Have you enough fuel to get there? Better too much than too little!
3. Check for any loose articles that could trail or fall into the propeller while flying and
fasten them securely.
4. If you spot a problem, not matter how small, deal with it NOW!
5. Always put on and fasten your helmet before clipping into the harness.
6. Always carry out full pre-flight checks before launching.
7. Don’t fly into danger – over water, tree, power lines etc where an engine failure will
leave you in trouble.
8. Try not to fly in the turbulence of your own wake or that of others, especially at low
altitude.
9. Except for collision avoidance, making a sharp turn against the tor ue effect during
steep climbs can be dangerous: you may rapidly stall and enter a spin.
10. Avoid downwind low flying: it drastically reduces your options.
11. Be sensitive to mechanical problems early. A noticeable change in engine tone or a
new vibration may spell trouble. Land and check it out!
12. Remember, not everyone enjoys your engine noise. Care must be taken when flying
near livestock.
13. Never take-off towards areas of potential rotor, towards trees or buildings on the
lee side of a hill.
14. Never touch any part of the propeller guard when the engine is running.
15. Always be aware of the weather, never fly if large cumulus clouds are brewing and
never fly in the rain.
17. Never fly below the lee side of a hill, rotor is dangerous!!

FITTING THE PROPELLER BLADES
Fit the 3 propeller blades to the driven pulley in the order outlined below
1. Insert 2 of the 6 (M8 x 60mm) bolts into the prop disc and locate a single blade in
position. Ensure that each bolt has both a split spring washer then normal spreader
washer located on its shank before locating in the prop disc.
2. Locate a single blade in position on these two bolts and lightly screw the bolts into
position on the driven pulley.
3. Follow the same procedure for each blade but do not tighten the bolts until all three
blades are in position.
4. Finally tighten each bolt with e ual tor ue hand tight only (be careful not to over
tighten and crush the carbon fibre propeller hubs)
Note – When installing the propeller, the propeller blade bolts should not be o er-
tightened or the base of the propellers could be damaged, distorted and weakened.

ASSEMBLING THE 3-PIECE PROPELLER GUARD
Fit the three pieces together as shown in the illustration below. The two lower sections should
be clicked into position first. The top section can then be clicked into position, to do this lightly
press the curved central support onto its aerofoil connector and simultaneously locate the two
circular side connectors. DO NOT PRESS FIRMLY INTO POSITION UNTIL THE OUTER RING
CONNECTORS ARE LOCATED. Next locate the left and right hand outer ring connectors. Lightly
press them into position but do not depress the button clips. Now that all the connection points
are in position, the central upright should be firmly pressed into position and the button clip
depressed to lock this position. The outer ring connectors can now be locked in also. This
process re uire a little techni ue, but once developed can be snapped together and
disassembled in under a minute. This is the fastest and most durable design of propeller guard.
Note - The propeller guard is designed to prevent canopy lines and other foreign objects from
being drawn into the propeller and are not intended to protect the pilot. Therefore,
always use extreme caution and never touch any part of the propeller guard while flying or
running the engine on the ground.

CHARGING THE STARTER BATTERY
Every Volution should arrive with the battery installed in position and ready charged. Do not
however expect the battery to be fully topped up at the time of shipping. For this reason it is
advised that you top up your starter battery before attempting to fly your Volution.
USE THE PARAJET CHARGER SUPPLIED WITH YOUR UNIT
Note: When your Volution is being flown regularly it will not be necessary to charge the battery
as the in-built generator charges it automatically.
However, if you do not fly your Volution for more than 4 weeks your battery will re uire
charging, simply plug the Parajet charger into the charging socket on your power unit for a
minimum of 24 hours
1. To remove the battery, simply unlock the harnesses upper retaining bar from the chassis. Fold the
harness down away from the body of the power unit to expose the electronics case.
2. Remove the case cover by hinging the top out first, the bottom can then be pulled up and out of
position.
3. The battery will now be exposed at the base of the electronics box. The positive terminal is insulated
with a press-fit rubber boot. This must be pulled back to expose the terminal that must be disconnected.
4. Disconnect both terminals before removing the battery.
5. IMPORTANT: When you replace the battery be sure to push the insulating boot firmly over the positive
terminal. Failure to do so will cause the battery to short out on the body of the machine which could
result in fire or damage .

REDUCTION BELT ADJUSTMENT
The transmission belt is well adjusted at the time of shipment, but it could become slack
during initial operations. When necessary adjust it so as to keep it always in an optimum
state of tension. Referring to the picture below adjust reduction belt tension as outlined
in these steps. A high pitch revving noise from the engine is a sign that the belt has
become loose. Be sure to tighten the belt as soon as possible or you could damage it.
1. Remove the propeller from the driven pulley.
2. Loosen the prop shaft retaining nut and then screw (A) NB. They will be very tight!!
3. Insert the 5mm hex key into the hole in the side of the prop shaft. (B)
4. To tension the belt, firmly rotate the shaft clockwise. This in turn will enable the
eccentric prop shaft to increase the belt tension. It will be very stiff to move.
5. Once the belt has reached the re uired tension simply re-tighten the prop shaft
retaining screw and nylock nut. (see diagram below for belt tension setting)

FITTING THE WEIGHT-SHIFT HARNESS
The weight-shift design enables pilots to control flight direction purely by shifting centre
of gravity in the harness. To do this simply lean in the desired direction and swing one
leg over the other to accentuate the turn. This creates a very efficient smooth turn
which re uires no brake input.
Fittin the wei ht-shift harness:
1. Start by locking the harnesses upper
retaining bar onto the chassis as shown
below. NB. Ensure Button Clip locates
properly and pops into hole as arrowed..
2. At the base of the harness on the
reverse side there are 2 steel rings
pressed into the webbing tabs. These
line up with 2 corresponding M6
threaded inserts located in each chassis
upright approximately 10cm from the
base.
3. Using the two M6 x 12mm socket screws
and large flange washers tighten the harness
webbing into position against the chassis
uprights.
4. At the front of the harness are 2 webbing
loops. Using the stainless steel shackles
attached to the swing arms attach the
webbing loops to the first hole in the swing
arm.
5. Attach carabiner connection points to the
corresponding weight setting on the swing
arms. (See next page)

ADJUSTING THE WEIGHT SHIFT HARNESS
To adjust this type of harness to the optimum weight setting, position the hang-point
mallion and off-set pin as shown below. The weight ranges are given in the diagram.
IMPORTANT – If the harness is not set up correctly it will result in poor handling and
uncomfortable flying. It is vital therefore that the steps described below are followed
accurately.
CAUTION!!! If the pilot is too heavy for the chosen harness setting this will cause the
Volution to ride up on the pilots back. This makes for an uncomfortable flying position
and also causes the top of the propeller guard to press near to the paraglider brake
handles which is potentially very dangerous. If you suspect this it is important that you
land as soon as possible and re-set the hang points moving them one or two settings
forward.
NOTE – Due to the dynamic nature of this harness it may take some flying time to
become accustomed to the flying style. It may also take a few flights to decide which
hang-point position is most comfortable and effective for you. You will notice that on
full power the flying position is more upright and that when you reduce throttle the
position is more laid back. The engine off position is designed to be similar to the free
flying position which is more comfortable and improves weight shift for thermalling.

NB.
The Volution weight shift harness is designed to offset the
tor ue reaction of the propeller. This enables the pilot to fly
straight even on full power. The system uses the pilot’s weight to
counter the tor ue by off-setting both karabiners to the right as
the pilot sits in the harness. See arrows above.
Important: Always ensure that both rubber off-set covers are
fully tightened in position pointing to the left as you look at the
harness before you get in to fly (as above) If you are sitting in the
harness they should both point to the right. This is essential!!

MIXING FUEL AND OIL
Use only unleaded regular petrol (95 - 98 octane) and high-grade 2-stroke oil for air-
cooled engines. BP Super 2-Stroke and Castrol TTS are recommended.
Other oils can be substituted but any oil used should be for air-cooling chemical
synthesis and medium rotation. Check with your manufacturer or our service centres or
any authorised Parajet dealer for the best type of oil available in your area.
1. Mix petrol and oil at a ratio of 50:1 (100mm Oil for 5 litres of unleaded petrol)
2. Shake and mix fuel and oil well.
3. Always use freshly mixed petrol and oil not more than 4 weeks old
4. Use standard unleaded fuel (95 – 98 octane is standard)
5. Only use recommended oil.
FILLING THE FUEL TANK
1. Remove the tank cap. (rotate counter clockwise)
2. Pour the fuel mixture into the fuel tank.
3. Fill tank to 20mm below level of filler (8.5 litres) For maximum flight range fill to the
top (3- 4mm beneath cap level total of 9.5 litres)
4. Tighten fuel cap securely. (be sure not to cross thread the cap as it will not seal
correctly)
Note
•Do not fill above this level.
•Be careful of fuel spillage and wipe dry should any occur.
•Be sure the fuel is clean. Although there is a fuel filter in the fuel tank Dirt, dust
and other foreign objects can clog the filter and cause the engine to run poorly
or stop.
Caution!
•Never leave the engine running when refueling.
•Observe the ‘No Fire’ rules; keep all inflammable objects well away from fuel.

PRIOR TO STARTING THE ENGINE
1. Check carefully the surrounding area before taking out your unit.
2. Be sure to choose a flat bit of ground which is well ventilated. Do not start the
engine indoors or other poorly ventilated areas.
3. Be sure nothing is within 3 meters of your unit.
4. Conduct a complete pre-flight check of your unit, especially looking for oil and gas
leaks. Check the unit carefully for loose nuts or bolts, bent or damaged frame or any
other type of damage.
5. Check level of fuel mixture. Be sure it is freshly mixed (less than 4 weeks old).
6. Check immediate area near the propeller for lines, ropes, clothing and anything that
could be caught in the moving propeller or drive pulleys.
7. Pilots with long hair should be especially careful to cover their head.
Warnin !!! - Stay Clear of this Area !!!
•Warn persons nearby before starting the engine- Make it a habit to shout ‘Clear
Prop’ in a loud and clear voice.
•The turning propeller can cause considerable damage and injury.
•Do not start engine indoors or other poorly ventilated areas.
•Be sure area is free from anything that could be entangled in propeller.
•Use only freshly mixed 50:1 regular petrol and oil recommended by Parajet. The
most common reason for engine damage is improper oil or petrol
•Only fill tank with the engine off and only after it has cooled down.
•Follow all “No Fire” rules.
Warning!!
Keep clear of moving propeller
Keep objects away from propeller

STARTING THE ENGINE
1. Push the choke valve into ‘choke’ position (closed. See following page for details)
2. Turn on the main switch located at the right side of the electronics case behind the
right side of the harness.
3. Make sure the throttle lever is in the idle position, DO NOT GRIP HANDLE.
4. Firmly hold the frame from the harness side. Rest your full body weight against the
harness side of the chassis using your shoulder and knee.
5. Hold down the green starter button until the engine fires once.
Warnin : Release reen starter button immediately after en ine fires once, failure
to release immediately will cause the en ine to flood.

ACTIVATING THE CHOKE VALVE
6. After first exhaust note is heard, push the choke valve back to its operating position.
IMPORTANT! Release the start button immediately after en ine fires once or you
will flood the en ine!!
7. If the engine fails to start repeat steps 1 to 5 again.
8. After the engine starts, warm it up for two or three minutes at low speed
revolutions.(be sure to read the section on engine break-in)
STOPPING THE ENGINE
1. Stop (kill) the engine only after releasing the throttle grip and allowing the engine to
return to idle speed.
2. Hold down the Stop button until the engine dies completely.
3. Turn off the Main switch. This cuts power to the starter motor and has been designed
as a safety measure. Make it a steadfast rule to turn off the Main Power to avoid
inadvertent starts and accidents.
RE-STARTING THE ENGINE
When the engine is warm, leave the choke lever in the operating/open position and
follow step 2 through to 7 outlined in the section above ‘Starting the Engine’.
In flight, the pilot can restart the engine when flight conditions are suitable. Be sure the
throttle is in idle position when re-starting the engine.

CARBURETOR ADJUSTMENT
Warnin ! When running the engine on the ground for the carburetor adjustments and
checking the thrust power, be sure to place the unit on flat and level ground, rest your
full body weight against the chassis, and check the throttle cable is clear of propeller.
The power and idle needles control the lubrication received by the engine. Basic
adjustments are made with:
1. Idle adjust screw – clockwise to increase and anti-clockwise to decrease.
2. L-needle - clockwise to decrease mixture flow to carburetor, anti-clockwise to
increase flow, (for initial acceleration).
3. H-needle - clockwise to decrease flow, anti-clockwise to increase flow, when throttle
is fully open for acceleration.

CARBURETOR ADJUSTMENT (continued)
Note – Adjustments should be done carefully. Warm-up the en ine for 3 to 4 minutes
before attemptin to make any carburetor adjustments. Be aware that chan es in the
barometric pressure, humidity, and round altitude affect the carburetor and en ine
performance.
Step 1 – With the engine off , start by turning the needles all the way in (clockwise) but
do not force them. Check to see that the tension springs are lightly depressed. Then set
the Low and High needles at 1 ½ turns front seat. These are factory settings. This puts
both on the rich side and leaner adjustments can be made as needed. Any other
adjustments should be made to ±⅛ turns in either direction. Too lean an adjustment can
cause improper lubrication and damage the engine.
Step 2 – Adjust the idle adjust screw to stabilize idle rpm at 2000rpm ± 100. If this
setting is too difficult to obtain, turn off the engine and restart before trying again.
Step 3 – Engage full throttle and check acceleration. If the engine fails to accelerate
smoothly or seems to stop, then turn the L-needle ⅛ clockwise . Further adjustments by
⅛ turn can be made but should this fail to correct the problem then another cause for
poor acceleration is suspected (probable). Trouble shoot further or contact your dealer
or a Parajet service representative for assistance.
Step 4 – Adjust the idle adjust screw again to stabilize idle at 2000rpm ± 100. Again
engage full throttle for 5 to 10 seconds and return to idle. Repeat Steps 4 and 5 until idle
is stable. Do not exceed ½ turn clockwise. The L- needle should always be at least 1 full
turn open from seat (CCW).
(H) Needle rotate 1/8 turn CW or
CCW for top end power
(L) Needle rotate 1/8 turn CW or
CCW to set first 70% of rev range. If
engine dies when throttle is
opened, turn CCW ¼ turn
