Therefore, some changes, modifications and improvements may not be covered in the operating instructions.
2. Safety Precautions and Working Techniques
Special safety precautions must be observed when working with a power tool.
It is important you read and understand the operating instructions before using your machine for the first
time. Always keep the Operating Instructions with the EZ300 for future reference. Non-observance of
the safety precautions may result in serious or even fatal injury.
Observe all application such as local safety regulations, standards and ordinances for ex. Gouvernement, Insu
rances, Associations etc.
If you have not used this type of power tool before: Have your dealer or other experienced user show you how to
operate your power tool properly.
Minors should never be allowed to use a electrical machine except for minors of more than 16 years and trained
under supervision for their apprentice.
Bystanders, especially children, and animals should not be allowed in the area where a power tool is in use.
When the machine is not in use, shut it off and place it so that it does not endanger others. Secure it against
unauthorized use.
The power tool user is responsible for avoiding injury to third parties or damage to their property.
Do not lend or rent your machine without the operating instructions. Be sure that anyone using the EZ300
understands the information contained in the operating instructions.
In some countries the operation of noise emitting power tools is restricted by local regulations. Observe country
specific requirements and regulations.
Accessories and Spare Parts
Only use genuine replacement parts and accessories that are explicitly approved for the EZ300 by ZEITLER AG.
These parts are specifically designed to match your machine model and meet your performance requirements
and also to avoid the risk of accidents and damage to the machine. If you have any question in this respect,
consult an authorized servicing dealer.
Never attempt to modify your power tool in any way since this will increase the risk of personal injury.
ZEITLER AG excludes all liability for personal injury and damage to property caused while using unauthorized
attachments.
Physical Condition
To operate the power tool you must be rested, in good physical condition and mental health. If you have any
condition that might be aggravated by strenuous work, check with your doctor before operating a power tool.
Persons with pacemakers only: The ignition system of your power tool produces an electromagnetic field of a very
low intensity. This field may interfere with some pacemakers. To reduce health risks, ZEITLER AG recommends
that persons with pacemakers consult their physician and the pacemaker manufacturer before operating this tool.

Operating Manual EZ300 Version 05/2021 page 5 / 30
Do not operate the power tool if you are under the influence of any substance (alcohol, drugs) which might impair
visions, dexterity of judgement.
Applications
The EZ300 Pull Line Blower is intended exclusively for blowing in or sucking out special pull lines in pipe work
that has already been laid. Then, cables or extra strong pull lines can be fixed to the pull line in order to pull them
through the pipe work.
It must not be used for any other purpose because of the increased risk of accidents and damage to the machine.
Never attempt to modify your power tool in any way since this may result in accidents or damage to the machine.
Disposal of lines
Used lines can also be used for other purposes of must be properly disposed of. All relevant regulations and laws
of the particular country must be complied with when disposing of old lines.
Personal protective Equipment
Wear proper protective clothing and equipment.
Clothing must be sturdy but allow complete freedom of movement. Wear snug-fitting clothing, an overall
and jacket combination, do not wear a work coat.
Avoid any clothing, scarves, neckties, jewellery or anything that could get into the air intake.
Tie up and confine long hair (e.g. with a hair net, cap, hard hat, etc.)
Wear sturdy shoes with non-slip soles.
Wear safety glasses and ‘personal’ hearing protection, e.g. earplugs or ear muffs.
Fueling
Gasoline is an extremely flammable fuel. Keep clear of naked flames, do not spill any fuel –do not
smoke.
Always shut off the engine before refuelling.
Do not fuel a hot engine –fuel may spill and cause a fire.
Open the fuel cap carefully to allow any pressure build-up in the tank to release slowly and avoid fuel spillage.
Fuel your power tool in a well-ventilated area, outdoors only. If you spill fuel, wipe the machine immediately –if
fuel gets on your clothing, change immediately.
To reduce the risk of serious or fatal burn injuries, check for fuel leakage. If fuel leakage is found, do
not start or run the engine until leak is fixed.
Tighten down the fuel cap as securely as possible. This reduces the risk of unit vibrations causing the fuel cap to
loosen or come off and spill quantities of fuel.

Before Starting
Check that your power tool is properly assembled and in good condition –refer to appropriate chapters in the
operating instructions.
•Throttle trigger must move freely and spring back to the idle position when released
•Setting lever/switch must move easily to position STOP or 0
•Check that the spark plug boot is secure –a loose boot may cause arcing that could ignite combustible
fumes and cause a fire
•Check condition of fan wheel and fan housing
•A worn fan housing (cracks, nicks, chips) may result in an increased risk of injury from thrown foreign
objects
•If either the fan wheel or fan housing is damaged, consult your dealer –ZEITLER AG recommends you
contact a service dealer
•Never attempt to modify the controls of the safety devices in any way
To reduce the risk of personal injury, do not operate your machine if it is damaged or not properly assembled.
Starting the Engine
Start the engine at least 3 meters from the fueling spot, outdoors only.
Your power tool is designed to be operated by one person only. Do not allow other persons in the work area –
even when starting the engine.
Do not drop start the engine –the correct starting procedure is described in the Operating Instructions.
Make sure to place the unit on level ground, to have secure footing, and do hold the unit securely.
As soon as the engine starts, the air flow may throw small objects (e.g. stones) in all direction.
During Operation
Do not direct the air blast towards bystanders on animals since the air flow can blow small objects at great
speed –risk of injuries.
In the event of impending danger or in an emergency, switch off the engine immediately by moving the setting
lever/switch to STOP or 0.
To reduce the risk of injury by thrown objects, do not allow other persons within 5 meters of your own position.
Never leave a running machine unattended.
Take special care in slippery conditions, on slopes or uneven ground.
Watch out for obstacles such as tree stumps, roots and ditches which could cause you to trip or stumble.
Never work on a ladder or any other insecure support.
Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts,
alarms, etc.) is restricted.
To reduce the risk of accidents, take a break in good time to avoid tiredness or exhausting.
Work calmly and carefully –in daylight conditions and only when visibility is good. Stay alert so as not to
endanger others.
After finishing work, put the unit down on a level, non-flammable surface. To reduce the risk of fire, do not put it
down near easily combustible materials (e.g. wood chips, bark, dry grass, fuel)
Your power tool produces toxic exhaust fumes as soon as the engine is running. These fumes may be
colourless and odourless and contain unburned hydrocarbons and benzol. Never run the engine indoors or in
poorly ventilated locations.
To reduce the risk of serious or fatal injury from breathing toxic fumes, ensure proper ventilation when working
in ditches, hollows or other confined locations.
Optional accessories: air hose of 2 m for extension (see ‘To use accessories’)
To reduce the risk of accidents, stop work immediately in the event of nausea, headache, visual disturbances
(e.g. reduce field of vision), problems with hearing, dizziness, deterioration in ability to concentrate. Apart from
other possibilities, these symptoms may be caused by an excessively high concentration of exhaust gases in the
work area.
The dust that occurs during operation may be harmful to health. If dust levels are very high, wear a suitable
protective mask.
To reduce the risk of the fire, do not smoke while operating or standing near your power tool. Note that
combustible fuel vapour may escape from the fuel system.
If your power tool was exposed to unusual influences for which it was not designed (e.g. heavy impact or a fall)
always check that it is in good condition before continuing work –see also ‘Before Starting Work’. Check the fuel
system in particular for leaks and make sure the safety devices are working properly. Do not continue operating
your power tool if it is damaged. In case of doubt, have the machine checked by your servicing dealer.

Vibrations
Prolonged use of the power tool may result in vibration-induced circulation problems in the hands (whitefinger
disease).
No general recommendation can be given to the length of usage because it depends on several factors.
The period of usage is prolonged by:
•Keeping your hands warm
•Work breaks
The period of usage is shortened by:
•Any personal tendency to suffer from poor circulation (symptoms: frequently cold fingers, itching)
•Low outside temperatures
•Gripping force (a tight grip hinders circulation)
Continual and regular users should monitor closely the condition of their hands and fingers. If any of the above
symptoms appear (e.g. tingling sensation in fingers), seek medical advice.
Maintenance and Repairs
Service the machine regularly. Do not attempt any maintenance or repair work not described in the operating
instructions. Have all other work performed by a servicing dealer.
ZEITLER AG recommends that you have servicing and repair work carried out exclusively by an authorized
servicing dealer for EZ300. Service dealers are regularly given the opportunity to attend training courses and are
supplied with the necessary technical information.
Only use genuine replacement parts and accessories that are explicitly approved for the EZ300 by ZEITLER AG.
These parts are specifically designed to match your machine model and meet your performance requirements
and also to avoid the risk of accidents and damage to the machine. If you have any question in this respect,
consult an authorized servicing dealer.
Never attempt to modify your power tool in any way since this will increase de risk of personal injury.
ZEITLER AG excludes all liability for personal injury and damage to property caused while using unauthorized
attachments.
To reduce the risk of injury from unintentional engine startup, always shut off the engine and disconnect the
spark plug boot before performing any repairs, maintenance or cleaning work. –Exception: carburettor and idle
speed adjustments.
Do not turn the engine over on the starter with the spark plug boot or spark plug removed since there is otherwise
a risk of fire from uncontained sparking.
Do not service or store your machine near open flames.
Check the fuel filler cap for leaks at regular intervals.
Use only a spark plug of the type approved by ZEITLER AG and make sure it is in good condition –see
‘Technical data’.
Inspect the ignition lead (insulation in good condition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire and damage to hearing, do not operate your machine if the muffler is damaged or
missing.
Do not touch a hot muffler since burn injury will result.
Vibration behaviour is influenced by the condition of the AV elements –check the AV elements at regular
intervals.
Shut off the engine before dealing with problems.

8. Blowing mode with EZ300
1. Conduit ends must be clean and cut off evenly
(if not possible →use orange cone)
2. Decide on the conduit end at higher level
3. Post control person on opposite side (where device is not in use).
(eye protection, wear safety goggles)
4. Fill the tank with the mixture of gasoline and engine oil –see instructions
5. Adjust blowing connection (bayonet catch)
6. Fix head piece or special equipment appropriate to conduit Ø
7. Provide shuttle suitable for pipe inside diameter
TOLERANCE to inside Ø + 0 / -2 mm (see shuttle installation)
8. Start the engine according to the instructions
9. Apply foam ring close to conduit
10. First blow through the tube with air only (dirt, dust, water)
11. Check volume of air flowing out (be careful!)
12. Switch off the engine
13. Insert the pull line through the pull line supply and knot it tightly to the screw of the shuttle, with only
a short end left
14. Place the corresponding shuttle in conduit
15. Start the engine
16. Place the foam ring close to the conduit and blow in the pull line without interruption
17. Increase blowing speed by throttle lever, if necessary lock throttle lever
18. DO NOT block air intake/screen of the EZ300 with clothing or body
19. As soon as the shuttle has reached the end of the conduit, the pull line stops uncoiling
- if the shuttle pauses: pull back by hand and try from the opposite side or with alternative
accessories (see use of accessories eg. suction mode)
20. Store the device in a safe place and switch off the engine as instructed
21. Insert side: cut the line and secure it from retraction
22. Outlet side: release shuttle and secure line from retraction
Blowing mode completed: always remove head piece and blowing connection!
How to couple two pull lines rolls:
If the existing line length of one roll is not sufficient, you may add another line roll:
1. You are working with a started roll of pull line, make sure to secure the end of the line so that it
cannot slip into the duct (large knot / tie object)
2. Stop the blowing process on time before the end of the line
3. Release the knot / object and carefully pull the remaining line completely through the line supply
4. Thread the line start of the second roll through the line supply
5. Tie the end of the first roll firmly and strongly to the start of the second roll (for example, with a
Figure Eight (Flemish) knot)
6. Place the EZ100 tight to the duct and continue blowing
7. When working with a parachute make sure to keep pull line tense, to keep parachute open.
ATTENTION: connecting two roll ends automatically reduces the tensile strength
NEVER BLOW IN SHUTTLE WITHOUT PULL LINE –
MAY GET STUCK OR LOST IN THE DUCT AND CAN’T GET PULLED BACK.

10. Fuel
Your engine requires a mixture of gasoline and engine oil.
For health reasons, avoid direct skin contact with gasoline and avoid inhaling gasoline vapor.
STIHL MotoMix
ZEITLER AG recommends the use of STIHL MotoMix. This ready-to-use fuel mix contains no benzol or lead, has
high octane rating and ensures that you always use the right mix ratio.
MotoMix is specially formulated for use in STIHL engines and guarantees a long engine life.
MotoMix is not available in all markets.
Mixing Fuel
Unsuitable fuels or lubricants or mix ratios other than those specified may result in serious damage of
the engine. Poor quality gasoline or engine oil may damage the engine, sealing rings, hoses and the fuel
tank.
Gasoline
Use only high-quality brand-name gasoline with a minimum octane rating of 90 –leaded or unleaded.
Engine Oil
Use only quality two-stroke engine oil. We recommend STIHL two-stroke engine oil since it is specially formulated
for use in STIHL engines and guarantees a long engine life.
If STIHL two-stroke engine oil is not available, use only quality two-stroke oil designed for use in air-cooled
engines. Do not use oils designed for water-cooled engines or engines with a separate lubricating systems (e.g.
conventional four-stroke engines)
