SAFE OPERATION
•
Review the area to be trimmed. Look for hazards that could contribute to unsafe conditions. DO
NOT operate unit if any wires(power, telephone, cable, etc.) are closer than 15M (50ft.) to any
part of the operator or unit. (Fig.2-9)
•
Spectator and fellow workers must be warned, and children and animals prevented from coming
nearer than 15M (50ft.) while the pole saw is in use. (Fig.2-10)
•
•
Avoid all power lines. This unit is not insulated against electrical current.
Always wear head protection with full face shield to help protect against falling branches and
debris. (Fig.2-10)
Pruning techniques
This unit is designed for trimming small limbs and branches up to 8 'in diameter. Follow these tips for
successful operation.
•
•
•
•
Plan cut carefully. Check direction branch will fall.
Long branches should be removed in several pieces.
Do not stand directly beneath branch being cut.
When ready to cut:
Hold "front cutting guide" against branch. This will prevent whipping of the branch. DO NOT use
back and forth sawing action. (Fig. 2-11)
•
Look out for branch immediately behind the branch being cut. If blade hits rear branch
damage to blade may occur. (Fig. 2-12)
•
•
•
•
Accelerate to full throttle.
Apply a light cutting pressure.
Ease cutting pressure when nearing end of cut to maintain control.
When pruning a limb 4 inch diameter or larger, cut as follows: (Fig. 2-13)
1. Undercut 1/4 limb diameter near tree trunk.
2. Finish top cut slightly farther out on limb.
3. Flush cut stub at trunk.
•
DO NOT use for felling or bucking.

MAINTENANCE, REPLACEMENT, OR REPAIR OF THE
EMISSION CONTROL DEVICES AND SYSTEMS MAY
BE PERFORMED BY ANY NONROAD ENGINE REPAIR
ESTABLISHMENT OR INDIVIDUAL.
Carburetor adjustment (Fig. 3-1)
WARNING!
The cutting attachment may be spinning during carburetor adjustments.
WARNING!
Never start the engine without the complete clutch cover and tube assembled! Otherwise the clutch can come loose and
cause personal injuries.
In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is basically adjusted. A
further adjustment may be required, according to climate and altitude. The carburetor has one adjustment possibility:
T = Idle speed adjustment screw.
Idle speed adjustment (T)
Check that the air filter is clean. When the idle speed is correct, the cutting attachment will not rotate. If adjustment is
required, close (clockwise) the T-screw, with the engine running, until the cutting attachment starts to rotate.
Open (counter-clockwise) the screw until the cutting attachment stops. You have reached the correct idle speed when the
engine runs smoothly in all positions well below the rpm when the cutting attachment starts to rotate.
If the cutting attachment still rotates after idle speed adjustment, contact your service workshop.
NOTE!
Standard Idle rpm is 2500-3000 rpm.
WARNING!
When the engine is idling the cutting attachment must under no circumstances rotate.
Air filter (Fig. 3-2)
The air filter must be cleaned from dust and dirt in order to avoid:
• Carburetor malfunctions.
• Starting problems.
• Engine power reduction.
• Unnecessary wear on the engine parts.
• Abnormal fuel consumption.
Clean the air filter daily or more often if working in exceptionally dusty areas.
Cleaning the air filter
Remove the air filter cover and the filter (1).
Rinse it in warm soap suds. Check that the filter is dry before reassembly. An air filter that has been used for some time
cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged filter must always be
replaced.

Owner’s Manual
Fuel Filter (Fig. 3-2B)
Drain all fuel from fuel tank and pull fuel filter line from tank.
Pull filter element out of holder assembly. Replace filter if it
appears to be discolored or hardened from use. The filter
has a white, felt-like appearance when new.
Chain oil filter (Fig. 3-2C)
Remove the oil filter and thoroughly wash it in solvent.
Spark plug (Fig. 3-3)
The spark plug condition is influenced by:
• An incorrect carburetor setting.
• Wrong fuel mixture (too much oil in the gasoline)
• A dirty air filter.
• Hard running conditions (such as cold weather).
These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting difficulties. If the engine
is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean
it and check the electrode gap. Readjust if necessary. The correct gap is 0.6 mm (.024”). The spark plug should be replaced
after about 100 operation hours or earlier if the electrodes are badly eroded.
NOTE!
In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped
with resistor spark plug, use same type of spark plug for replacement.
Muffler (Fig. 3-4)
Remove the muffler and remove excess carbon from the exhaust port or muffler inlet every 100 hours of operation.
Cylinder (Engine cooling) (Fig. 3-5)
The engine is air cooled, and air must circulate freely around engine and over cooling fins on cylinder head to prevent
overheating.
Every 100 Operating hours, or once a year (more often if conditions require), clean fins and external surfaces of engine of
dust, dirt and oil deposits which can contribute to improper cooling.
NOTE!
Do not operate engine with engine shroud or muffler guard removed as this will cause overheating and engine damage.

Side case (Fig. 5-3)
Always keep the side case and drive area clean of saw dust and debris.
Periodically apply oil or grease to this area to protect from corrosion as some trees contain high
levels of acid.
Angle transmission (Fig.5-4)
Check angle transmission or angle gear for grease level about every 50 hours of operation by
removing the grease filler plug on the side of angle transmission.
If no grease can be seen on the flanks of the gears, fill the transmission with a quality lithium
based multipurpose grease up to 3/4.
Do not completely fill the transmission.
Spark Arrestor
If your unit comes with spark arrestor screen and yet your local regulation requires use of
spark arrestor for prevention against a possible fire, please attach it to the muffler by removing
muffler protector and other related parts. [The spark arrestor meet the regulation of SAE
J335-SEP90 and CSA CAN3-Z62.1-M77.]
