• Read this manual carefully until you completely understand
and can follow all safety rules, precautions, and operating
instructions before attempting to use the unit.
• Restrict the use of your pole pruner to adult users who
understand and can follow safety rules, precautions, and
operating instructions found in this manual. Minors should
never be allowed to use a pole pruner.
• Do not handle or operate a pole pruner when you are fatigued,
ill, or upset, or if you have taken alcohol, drugs, or medication.
You must be in good physical condition and mentally alert.
Pole pruner work is strenuous. If you have any condition that
might be aggravated by strenuous work, check with your
doctor before operating a pole pruner (Fig. 1). Be more
cautious before rest periods and towards the end of your
shift.
• Keep children, bystanders, and animals a minimum of 35 feet
(10 meters) away from the work area. Do not allow other
people or animals to be near the pole pruner when starting or
operating the pole pruner (Fig. 2).
• Major cases of pole pruner accidents happen when the chain
hits the operator. While working with the pole pruner, always
use safety protective approved clothing. The use of protective
clothing does not eliminate injury risks, but reduces the injury
effects in case of accident. Consult your trusted supplier to
choose equipment in compliance with legislation. The clothing
must be proper and not an obstacle. Wear adherent anti-cut
clothing. Anti-cut jackets (Fig.3), dungarees (Fig.3) and
leggings are ideal. Do not wear clothes, scarves, ties or
bracelets that may get stuck in wood or twigs. Tie up and
protect long hair (example with foulards, cap, helmets, etc.).
Safety shoes or boots having skid-proof sole and
anti-piercing insert (Fig.4). Wear protective helmet (Fig.5)
in places where there can be falling objects. Wear protective
goggles or face screens! Use protections against noises:
for example noise reduction ear guards (Fig.5) or earplugs.
The use of protections for the ear requests much more
attention and caution, because the perception of danger audio
signals (screaming, alarms, etc.) is limited. Wear anti-cut
gloves (Fig.6, page 8).
• Only loan your pole pruner to expert users who are completely
familiar with pole pruner operation and correct use. Give other
users the manual with operating instructions, which they have
to read before using the pole pruner.
• Check the pole pruner each day to ensure that each device,
whether for safety or otherwise, is functional.
• Never use a damaged, modified, or improperly repaired or
assembled pole pruner. Do not remove, damage or deactivate
any of the safety devices. Only use bars of the length indicated
by the manufacturer. Always replace bar, chain, immediately if
it becomes damaged, broken or is otherwise removed.
• Carefully plan your pole pruning operation in advance. Do not
start cutting until you have a clear work area, secure footing,
and planned retreat path.
• All pole pruner service, other than the operations shown in the
present manual, have to be performed by competent personnel.
• The pole pruner must only be used for cutting wood. It is
unadvisable to cut other types of material.
• It is unadvisable to hitch tools or applications to the P.t.o. that
are not specified by the manufacturer.

Precautions to Reduce Vibration Risk
• The pole pruner is provided with anti-vibration (AV) system; never alter or modify it.
• Wear gloves and keep your hands warm.
• Keep the pole pruner chain sharp and the pole pruner, including the AV system, well maintained. A dull chain
will increase cutting time, and pressing a dull chain through wood will increase the vibrations transmitted
to your hands.
• Maintain a firm grip at all times, but do not squeeze the handles with constant, excessive pressures, take
frequent breaks. All the above mentioned precautions do not guarantee that you will not sustain
whitefinger disease or carpal tunnel syndrome. Therefore, continual and regular users should monitor
closely the condition of their hands and fingers. If any of the above symptoms appear, seek medical
advice immediately.
Maintenance Precaution
WARNING: Never operate a pole pruner that is damaged, improperly adjusted, or is not
completely and securely assembled.
• Be sure that the pole pruner chain stops moving when the throttle control trigger is released. If the pole
pruner chain moves at idle speed, the carburetor may need adjusting, see Operation-Carburetor Adjusting
Section.
If the pole pruner chain still moves at idle speed after adjustment has been made, contact a Servicing
Dealer for adjustment and discontinue use until the repair is made.
WARNING: All pole pruner service, other than items in the Operator's Manual maintenance
instructions, have to be performed by competent pole pruner service personnel. (If
improper tools are used to remove the flywheel or clutch, or if an improper tool is used to
hold the flywheel in order to remove the clutch, structural damage to the flywheel could
occur which could subsequently cause the flywheel to burst and serious injury could
result.)
• Never modify your pole pruner in any way.
• Keep the handles dry, clean, and free of oil or fuel mixture.
WARNING: Use only accessories and replacement parts recommended.
•
•
•
•
Never touch the chain or attempt to service the pole pruner while the engine is running.
Never use fuel for cleaning operations.
Keep the pole pruner in a dry place, off the ground with the chain guard on and the tanks empty.
If your pole pruner is no longer usable, dispose of it properly without damaging the environment by
handing it in to your local Dealer who will arrange for its correct disposal.
• Replace immediately any safety device when damaged or broken.
WARNING: The muffler and other parts of the engine (e.g. fins of the cylinder, spark plug)
become hot during operation and remain hot for a while after stopping the engine.
To reduce risk of burns do not touch the muffler and other parts while they are hot.

OPERATION
26
Hold control grip with right hand and shaft (Fig.25A) with left hand. On
PT 2700 Models left hand should hold sheath (C,Fig.26) area.
Optimum balance could be obtained with machine close the
body. Standing 60° with the ground (Fig.25B) makes work less
fatiguing.
To ease branch falling, cut lower branches first.
To cut larger branches (with diameter larger than 10 cm), cut it
into more parts (max length 20 cm), never cut the whole branch
(Fig.27).
Always cut at full throttle.
WARNING – Never work under the branch you are
cutting; beware of available space and falling pieces
that bounce anomalously on the ground (Fig.28A).
27
WARNING – Pay attention when working near electric
lines. Falling branches could cause short circuit. Never
approach the tool at less than 10 metres from electric
lines (Fig.28B).
Flush-cutting (Fig.29A) - To avoid tearing the bark, kickbacks or
bar pinching, always start by performing a relieving cut (1) on the
underside of the branch. Perform the cross-cut (2).
Particular cuts (PTX 2700)
The pole pruner permits:
- pruning of branches that are overhanging obstacles (Fig.29B)

link tangs hang out of the bar groove. See Fig. 31.
3. During normal pole pruner operation, the temperature of the
chain will increase. The drive link tangs of a correctly tensioned
warm chain will hang approximately .050” (1.25 mm) out of
the bar groove. See Fig. 32. To help determine the correct
warm chain tension, the tip of the combination wrench
(Fig. 33) can be used as a guide.
CAUTION: Chain tensioned while warm, may be too
tight upon cooling. Check the "cold tension" before
next use.
CAUTION: A new chain has to be retensioned more
often than one that has been in use for some time.
Breaking-in the Chain

14
New chains will stretch and must be tightened frequently.
Lift the chain out of the bar groove and lubricate the bar groove
with additional oil, see Fig. 34. Place the pole pruner on a piece
of cardboard or scrap plywood. Start the pole pruner (refer to the
Operation-Starting Engine Section) and allow it to run at moderate
speed for approximately one (1) minute. Stop the engine. Check
that the oil pump is working properly. The cardboard should have
excess oil from the chain rotation if the oil pump is working
properly, see Fig. 35. Adjust the chain tension (refer to
Operation-Chain Tension Section). Start the pole pruner again
and make a few cuts in a log to heat up the chain. Stop the
engine and re-adjust chain again. Repeat this process until the
chain retains proper warm tension adjustment as shown in Fig.
32 in Operation-Chain Tensioning Section. Never touch the
ground with the chain.
OPERATION
36
(Do Not Smoke!) (Fig. 38)
This product is powered by a 2-cycle engine and requires
pre-mixing gasoline and 2-cycle oil. Pre-mix unleaded gasoline
and 2-cycle engine oil in a clean container approved for gasoline
(Fig. 36).
RECOMMENDED FUEL: THIS ENGINE IS CERTIFIED TO
OPERATE ON UNLEADED GASOLINE INTENDED FOR
AUTOMOTIVE USE WITH AN OCTANE RATING OF 89 ([R + M] /
2) OR HIGHER (Fig. 37).
Mix 2-Cycle Engine Oil with gasoline according to the instructions
on the package. We strongly recommend the use of 2% (1:50)
Efco Two Cycle Engine Oil, which is specifically formulated for all
Efco air-cooled two-stroke engines.
The correct oil / fuel proportions shown in the table below are
suitable when using the Efco Two Cycle Engine Oil or an
equivalent high-quality engine oil (JASO specification FD or ISO
specification L-EGD). When oil specifications are NOT equivalent
or unknown use 4% (1:25) oil / fuel mixing ratio.
CAUTION: DO NOT USE AUTOMOTIVE OIL OR
2-CYCLE OUTBOARD OIL.
37
CAUTION: Never use a fuel with an alcohol percentage
higher than 10%; gasohol up to 10% alcohol or E10
fuel are acceptable.
When using an Oxygenated Gasoline a good practice of Fuel
Management is necessary.
Gasoline Oxygenated with alcohol readily takes/up water when it
is present; the water may be condensed out of humid air or be a
contaminant in the fuel system, including tank.
38
CAUTION:
- Match your fuel purchases to your consumption;
don’t buy more than you will use in one or two
months;
- Store gasoline in a tightly-closed container in a
cool, dry place.
The use of Oxygenated Gasoline may cause the occurrence of
vapor-lock easier.

Clean surface around fuel cap to prevent contamination.
Loosen fuel cap slowly.
Carefully pour fuel mixture into the tank. Avoid spillage.
Prior to replacing the fuel cap, clean and inspect the gasket.
Immediately replace fuel cap and hand tighten. Wipe up any
fuel spillage.
NOTE: It is normal for smoke to be emitted from a new engine
during and after first use.
WARNING: Check for fuel leaks, if any are found,
correct before use. Contact a Servicing Dealer if
necessary.
Chain Oil System
(Fig. 41)
The bar and chain require continuous lubrication. Lubrication is
provided by the automatic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and chain. Too little oil will
cause overheating shown by smoke coming from the chain and/or
discoloration of the bar. In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a small amount (5 to 10%)
of Diesel Fuel or kerosene. Bar and chain oil must be free flowing for
the oil system to pump enough oil for adequate lubrication.
41
CAUTION: Never use waste oil. Always use
biodegradable lubrificant that is specific for bar and
chain and that is better for the environment and pole
pruner’s parts.
CAUTION: Do not use dirty, used or otherwise
contaminated oils. Damage may occur to the oil
pump, bar, or chain.
16
OPERATION
en
WARNING: Do not use waste oil! Medical studies
have shown that renewed contact with waste oil can
cause skin cancer.
1. Fill the oil tank every time engine is fueled. Pole pruner should
use approximately one tank of oil per tank of fuel.
2. The automatic oil pump is a positive displacement pump
operated through gears driven off the clutch drum assembly.
The pump will not oil at idle speed.
42
Preparation for Cutting
Proper Grip on Handles.
Refer to Safety Section for appropriate Safety Equipment.
1. Wear non-slip gloves for maximum grip and protection.
43
WARNING: Hold the pole pruner firmly with both
hands. Always keep your LEFT HAND on the front
handle and your RIGHT HAND on the rear (throttle)
handle as shown in Fig. 42, so that your body is to
the left of the chain line. Never use a cross-handed
grip, or any stance which would place your body or
arm across the chain line. Left-handers should
follow these instructions too.
2. Maintain a proper grip on the pole pruner whenever the engine
is running. The fingers should encircle the handle. Any grip in
which the thumb and fingers are on the same side of the
handle, is dangerous because a slight kick of the pole pruner
can cause loss of control.
WARNING:
Proper Cutting Stance (Fig. 43)
- Weight should be balanced on both feet - feet on
solid ground.
- Your body should always be to the left of the
chain line.
Basic Cutting Procedure
Practice cutting a few small logs using the following technique to
get the "feel" of using your pole pruner before you begin a major
pole pruning operation.
1. Take the proper stance in front of the wood with the pole
pruner idling.
2. Accelerate the engine to full throttle just before entering the cut
by squeezing the throttle trigger.
3. Keep the engine at full throttle the entire time you are cutting.
4. Allow the chain to cut for you; exert only light downward
pressure. If you force the cut, damage to the bar, chain, or
engine can result.
5. Release the throttle trigger as soon as the cut is completed,
allowing the engine to idle. If you run the pole pruner at full
throttle without a cutting load, unnecessary wear or
damage can occur to the chain, bar, and engine.
6. Do not put pressure on the pole pruner at the end of the cut.

• Never allow children to operate your pole pruner. Only allow
others to use this pole pruner who have read this Operator's
Manual or received adequate instructions for the safe and
proper use of this pole pruner.
• Keep everyone - helpers, bystanders, children, and animals a
safe distance from the cutting area (Fig. 44).
• Always cut with both feet on solid ground to prevent being
pulled off balance.
• Do not cut above chest height, as a pole pruner held higher is
difficult to control against kickback forces.
• Do not work near electrical wires or buildings. Leave this
operation for professionals.
• Cut only when visibility and light are adequate for you to see
clearly.
• Do not cut from a ladder, this is extremely dangerous.
• Stop the pole pruner if the chain strikes a foreign object.
Inspect the pole pruner and repair parts as necessary.
• Keep the chain out of dirt and sand. Even a small amount of
dirt will quickly dull a chain and increase the possibility of
kickback.
• Stop the engine before setting the pole pruner down.
• Be particularly cautious and alert while wearing hearing
protection because such equipment may restrict your ability to
hear sounds indicating danger (calls, signals, warnings, etc).
• Be extremely cautious when working on slopes or uneven
ground.
Starting The Engine
WARNING: Keep body to the left of the chain line.
Never straddle the pole pruner or chain, or lean over
past the chain line.

OPERATION
en
Breaking-in the Engine
The engine reaches the maximum power after 5-8 hours of activity.
During this period of breaking-in do not make the machine
function idly at full throttle, to avoid excessive functioning
stress.
CAUTION! – During the braking-in period do not vary
the carburetion to obtain a presumed power
increment; the engine can be damaged.
51
Difficult Starting (or starting a flooded engine)
The engine may be flooded with too much fuel if it has not started
after 10 pulls. Flooded engines can be cleared of excess fuel by
following the warm engine starting procedure listed above.
Ensure the ON/STOP switch is in the ON position. Starting could
require pulling the starter rope handle many times depending on
how badly the unit is flooded. If engine fails to start refer to the
TROUBLESHOOTING TABLE (page 30).
Engine is Flooded
52
53
If you did not move the choke lever to warm start, quickly enough
after the engine began to fire, the combustion chamber is
flooded.
• Set the on/off swich to STOP.
• Engage a suitable tool in the spark plug boot (Fig. 51).
• Pry off the spark plug boot.
• Unscrew and dry off the spark plug.
• Open the throttle wide.
• Pull the starter rope several times to clear the combustion
chamber.
• Refit the spark plug and connect the spark plug boot, press it
down firmly – reassemble the other parts.
• Set the on/off swich to I, the starting position.
• Set the choke lever to warm start – even if engine is cold.
• Now start the engine.
Stopping The Engine
Release the throttle trigger (B, Fig. 52) and let the engine return
to idle.
To stop the engine, move the on/off switch (A) to the “STOP”
position. Do not put the pole pruner on the ground when the saw
chain is still moving.
In the event that the “STOP” position of the switch will not
function, pull the choke lever in the CLOSE position
(Fig.48, page 19) to stop the engine.
CAUTION: The chain contracts as it cools down. If it
is not slackened, it could damage the sprocket shaft
and bearings.
Pre-operation checking
WARNING: THE SAW CHAIN SHOULD NEVER TURN
AT IDLE. Turn the idle speed screw “T”
counterclockwise to reduce the idle RPM and stop
the chain, or contact a Servicing Dealer for
adjustment and discontinue use until the repair is
made. Serious personal injury may result from the
pole pruner chain turning at idle.

Working Techniques
Unusual Hazardous Working Techniques Conditions
WARNING: Do not work during periods of high wind or heavy precipitation.
WARNING: Never cut, when visibility is poor or in very high or low temperatures or in freezing
weather.
WARNING: Do not cut near electrical wires or buildings. If the tree makes contact with any utility line,
the utility company should be notified immediately.
WARNING: Check the tree for damaged or dead branches that could fall and hit you during
working.
• Carefully plan your pole pruning operation in advance.
• Clear the work area. You need a clear area all around the tree so you can have secure footing.
Look for decay and rot. If the branch is rotted, it can snap and fall toward the operator.
Make sure there is enough room for the branch to fall. Maintain a distance of 2-1/2 tree lengths from the nearest
person or other objects. Engine noise can drown out a warning call. Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where cuts are to be made.
Pick your escape route (or routes in case the intended route is blocked). Clear the immediate area around the tree,
and make sure there are no obstructions in your planned path of retreat.
WARNING: Never turn pole pruner upside down to undercut. The pole pruner cannot be controlled in
this position. Always make your first cut on the compression side of the branch. The compression
side of the branch is where the pressure of the branch’s weight is concentrated.
Pruning
• Be alert for springback. Watch out for branches that are bent or under pressure. Avoid being struck by the branch
or the pole pruner when the tension in the wood fibers is released.
• Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them.
WARNING: Never climb into a tree to limb or prune. Do not stand on ladders, a log or in any position
which can cause you to lose your balance or control of the pole pruner.
Pruning Operation (Fig. 53)
• When pruning trees it is important not to make the flush cut next to the main limb or trunk until you have cut off
the limb further out to reduce the weight. This prevents stripping the bark from the main member.
• Underbuck the branch 1/3 through for your first cut, your second cut should overbuck to drop the branch off.
• Now make your finishing cut smoothly and neatly against the main member so the bark will grow back to seal the
wound.

1. Remove the two (2) bar nuts (A, Fig. 55) and the cover (B).
2. Adjust the chain tensioning pin (C) fully towards the cover
band by turning the chain tensioning screw (D) counterclockwise
as shown in inset (Fig. 56).
3. The guide bar (E, fig. 57) contains a bar stud slot that fits over
the bar studs (F). The guide bar also contains two chain
tensioning pin holes (G) and two lubrication holes, one per
side. The bar is reversible and either tensioning pin hole may
be utilized with the chain tensioning pin.
4. Place the guide bar (E) onto the bar studs (F) as shown in
Fig. 57.
5. Position the guide bar (E) tip through the chain (H) loop as
shown in Fig. 58. The cutters on the top of the guide bar
should face toward the bar nose, in the direction of the chain
rotation. See inset (L) of Fig. 59.
6. Fit the chain (H, fig. 58) over the rim sprocket (M) and into bar
groove.
CAUTION: Severe damage can occur to the rim
sprocket, clutch drum, guide bar and chain, if the
chain is not correctly seated into the rim sprocket.
57
7. Replace the cover (B). Turn the chain tensioning screw (D)
clockwise until the chain tensioning pin (C) fits into the chain
tensioning pin hole (G). Install the two bar nuts (A). Tighten the
bar nuts finger tight only. The bar must be free to move for
tension adjustment.
CAUTION: Failure to ensure that the chain tensioning
pin is in the chain tensioning pin hole will result in
severe damage to the pole pruner during reassembly
of the sprocket cover.
58
8. Remove all slack from chain by turning the chain tensioning
screw (D) clockwise, assuring that the chain seats into the
bar groove during tensioning.
9. Lift the tip of the guide bar up to check for sag, see Fig. 60,
pag. 24. Release the tip of the guide bar, and turn the chain
tensioning screw (D) 1/2 turn clockwise. Repeat this process
until sag does not exist.
10. Hold the tip of the guide bar up and tighten the bar nuts (A)
securely as shown in Fig. 55.
11. Chain is correctly tensioned when there is no slack on the
underside of the guide bar, the chain is snug, but it can be
turned by hand without binding, see Fig. 61.

MAINTENANCE
62
63
64
65
For smooth and fast cutting, raker chain needs to be maintained
properly. The chain requires sharpening when the wood chips are
small and powdery, the chain must be forced through the wood
during cutting, or the chain cuts to one side. During maintenance
of your chain, consider the following:
1. Improper filing angle of the side plate can increase the risk of
a severe kickback.
2. Raker (depth gauge) clearance (A, Fig. 62): Too much increases
the potential for kickback; not enough decreases cutting
ability.
3. If cutter teeth have hit hard objects such as nails and stones,
or have been abraded by mud or sand on the wood, have
Servicing Dealer sharpen chain.
4. In rare instances drive tangs could flare resulting in chain not
rotating freely. Replace chain if necessary.
NOTE: Inspect the rim sprocket for wear or damage when
replacing the chain. If signs of wear or damage are present in the
areas indicated in Fig. 63, have the rim sprocket replaced by a
Servicing Dealer.
How to Sharpen the Cutters (Fig. 64)
Be careful to file all cutters to the specified angles and to the
same length, as fast cutting can be obtained only when all cutters
are uniform.
1. Wear gloves for protection. Tighten the chain tension enough
that the chain does not wobble. Do all of your filing at the
mid-point of the bar. See Operation-Chain Tension.
2. Use a 5/32" (4 mm) diameter round file and holder.
3. Keep the file level with the top plate of the tooth as shown in
Fig. 65. Do not let the file dip or rock.
4. Using light but firm pressure, stroke towards the front corner
of the tooth as shown in Fig. 66. Lift file away from the steel on
each return stroke.
5 Put a few firm strokes on every tooth. File all left hand cutters
(E, Fig. 67) in one direction. Then move to the other side and
file the right hand cutters (F) in the opposite direction.
Occasionally remove filings from the file with a wire brush.
CAUTION: Dull or improperly sharpened chain can
cause excessive engine speed during cutting which
may result in severe engine damage.
66
67
WARNING: It is absolutely essential to comply with
the angles and dimensions specified below. If the
pole pruner chain is incorrectly sharpened – and in
particular if the depth gauge is set too low – there is
a risk of increased kickback of the pole pruner, with
resulting risk of injury.
Failure to replace or repair damaged chain can
cause serious injury.
The pole pruner chain is very sharp, always wear
protective gloves when performing maintenance to
the chain.

Depth Gauge Clearance
1. The depth gauge (M, Fig. 70) should be maintained at a
clearance (N) between .020 (0.5 mm) and .024" (0.6 mm). Use
a depth gauge tool for checking the depth gauge clearances.
2. Every time the chain is filed, check the depth gauge
clearance.
Use a Flat File and a Depth Gauge Jointer to lower all gauges
uniformly (Fig. 71).
P) FLAT FILE
Q) DEPTH GAUGE JOINTER
Depth gauge jointers available in .020" to .035" (0.5mm to

adjoining drive links with the edge of the file.
CAUTION: After sharpening, clean the chain
thoroughly, remove filings or grinding dust – lubricate
the chain thoroughly.
71
72
26
Every day of use, reverse the guide bar on the pole pruner to
distribute the wear for maximum bar life (see Fig. 72). The bar
should be cleaned every day of use and checked for wear and
damage.
Feathering or burring of the bar rails is a normal process of bar
wear. Such faults should be smoothed with a file or stone as soon
as they occur.
A bar with any of the following faults should be replaced:
• Wear inside the bar rails which permits the chain to lay over
sideways.
• Bent guide bar.
• Cracked or broken rails.
• Spread rails.
In addition, guide bars with a sprocket at their tip must be
lubricated periodically with a grease syringe to extend the guide
bar life. Turn the guide bar and check that the lubrication holes
(T) and chain groove (S) are free from impurities.

This engine uses a NGK CMR7A with .02” (0.5 mm) electrode gap
(Fig. 79). Use an exact replacement and replace every six months
or more frequently, if necessary.
WARNING: Never test the ignition system with
ignition wire connector removed from spark plug or
with unseated spark plug, since uncontained
sparking may cause a fire. A loose connection
between spark plug terminal and ignition wire
connector in the boot may create arcing that could
ignite combustible fumes and cause a fire.
Use only resistor type spark plugs of the approved range.
Factors such as:
- too much oil in fuel mix;
- dirty air filter;
- unfavourable running conditions, e.g. operating at part load;
may result in rapid deterioration of the spark plug.
Muffler
WARNING – This muffler incorporates a catalytic
converter, needed in order to ensure the engine
complies with current emissions standards. Never
attempt to modify or remove the catalytic converter: in
doing so, you will be breaking the law.
WARNING – Mufflers with catalytic converters become
very hot during operation, and retain heat for a long
time after the engine has been stopped. This is the
case even with the engine idling. Contact can burn
the skin. Always remember the potential fire risk!
CAUTION – If the catalytic converter is damaged, it
must be replaced. If the catalytic converter frequently
becomes blocked, this could be an indication that the
efficiency of the muffler is limited.

Spark Arresting Muffler
The pole pruner is provided with a Spark Arrester System
p.n. 61280087 (Fig. 80) complying with the requirements of SAE
J335 standard; you can check the p.n. of the Spark Arrester
System on the muffler itself.
WARNING: A faulty or altered spark arrester system
screen can create a fire hazard.
80
81
Through normal use the screen can become dirty and should be
inspected weekly and cleaned as required.
To clean:
• Allow the muffler to cool.
• Remove the stop spring (A, Fig. 81).
• Remove the spark arrester screen (B).
• Clean and inspect the spark arrester screen.
• Reassemble components in reversed order of removal.
The Spark Arrester System needs a periodic and accurate
maintenance and cleaning, in particular:
- check periodically the spark arrester screen and substitute it
when holes, bends or deformations appear;
- check carefully if dust, debris or organic material is in contact
with parts of the Spark Arrester System; check especially the
gap between the muffler and the shield; clean it often with
tools or shop air.
WARNING: Do not operate your pole pruner if the
muffler is damaged, missing or modified. An
improperly maintained muffler will increase the risk of
fire and hearing loss.
82
Gear Housing
Every 30 working hours, remove screw (A, Fig. 82) on the gear
housing and check the quantity of grease. Use high quality
molybdenum bisulfide grease.

STORAGE
en
Storing Pole pruner
WARNING: Stop engine and allow to cool, and secure the unit before storing or transporting
in a vehicle. Store unit and fuel in an area where fuel vapors cannot reach sparks or open
flames from water heaters, electric motors or switches, furnaces, etc. Store unit with all
guards in place. Position so that any sharp object cannot accidentally cause injury to
passersby. Store the unit out of reach of children and other unauthorized persons.
1. Drain and clean the fuel tank in a well ventilated area.
2. Drain all fuel from tank into a container approved for gasoline. Run engine until it stops. This will remove all
fuel-oil mix which could become stale and leave varnish and gum in the fuel system.
3. Clean all foreign material from the pole pruner. Keep away from corrosive agents such as garden chemicals
and de-icing salts.
4. Abide by all Federal and local regulations for the safe storage and handling of gasoline. Excess fuel should
be used in other 2-cycle engine powered equipment.
CAUTION: It is important to prevent gum deposits from forming in essential fuel system parts
such as the carburetor, fuel filter, fuel hose, or fuel tank during storage. Alcohol blended fuels
(called gasohol or E10 or using ethanol, methanol) can attract moisture which leads to fuel
mixture separation and formation of acids during storage. Acidic gas can damage the
engine.
