SAFE OPERATION
CAUTION
○ Before starting, attach the harness to suspension eyelet and
hang from the shoulder.
Adjust the harness to be easy to use.
Always wear the harness during operation.
○ Pull emergency release fl ap in the event of emergency. (Fig. 44)
○ Always wear gloves during operation or maintenance.
○ 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 to any
part of the operator or unit. (Fig. 22)
○ Spectator and fellow workers must be warned, and children and
animals prevented from coming nearer than 15M while the pole
saw is in use. (Fig. 23)
○ 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. 24)
Pruning techniques
This attachment is designed for pruning 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. 24)
○ Look out for branch immediately behind the branch being cut, If
blade hits rear branch damage to blade may occur. (Fig. 25)
○ 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. 26)
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
MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION
CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED
BY ANY NON-ROAD ENGINE REPAIR ESTABLISHMENT OR
INDIVIDUAL.
Carburetor adjustment (Fig. 27)
WARNING
○ The cutting attachment may be spinning during carburetor
adjustments.
○ 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 fi lter 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 Tanaka dealer.
NOTE
Standard Idle rpm is 2500 – 3000 min
-1
.
WARNING
When the engine is idling the cutting attachment must under no
circumstances rotate.
Air fi lter (Fig. 28)
The air fi lter 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 fi lter daily or more often if working in exceptionally
dusty areas.
Cleaning the air fi lter
Remove the air fi lter cover and the fi lter (32). Rinse it in warm soap
suds. Check that the fi lter is dry before reassembly. An air fi lter
that has been used for some time cannot be cleaned completely.
Therefore, it must regularly be replaced with a new one. A damaged
fi lter must always be replaced.
Fuel fi lter (Fig. 29)
Drain all fuel from fuel tank and pull fuel fi lter line from tank. Pull fi lter
element out of holder assembly and rinse element in warm water with
detergent.
Rinse thoroughly until all traces of detergent are eliminated.
Squeeze, do not wring, away excess water and allow element to air
dry.
NOTE
If element is hard due to excessive dirt build-up, replace it.
Chain oil fi lter (Fig. 30)
Remove the oil fi lter and thoroughly wash it in solvent.
Spark plug (Fig. 31)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi lter
○ Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug electrodes, which
may result in malfunction and starting diffi culties. If the engine is
low on power, diffi cult to start or runs poorly at idling speed, always
check the spark plug fi rst. If the spark plug is dirty, clean it and check
the electrode gap. Re-adjust if necessary. The correct gap is 0.6
mm. 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.
Muffl er (Fig. 32)
Remove the muffl er and clean out any excess carbon from the
exhaust port or muffl er inlet every 100 hours of operation.
Cylinder
Authorized service dealer performs this maintenance.
NOTE
Do not operate engine with engine shroud or muffl er guard
removed as this will cause overheating and engine damage.
Oiler port (Fig. 33)
Clean the chain oiler port (33) whenever possible.
Guide bar (Fig. 34)
Before using the machine, clean the groove and oiler port (34) in the
bar with the special gauge off ered as an optional accessory.
Side case (Fig. 35)
Always keep the side case and drive area clean of saw dust and
debris.
