KombiSystem Guide to Using this Manual Safety Precautions and
Working Techniques
In the STIHL KombiSystem a number of different KombiEngines and KombiTools can be combined to produce a power tool. In this instruction manual the functional unit formed by the KombiEngine and KombiTool is referred to as the power tool.
Therefore, the separate instruction manuals for the KombiEngine and KombiTool should be used together for the power tool.
Always read and and make sure you understand both instruction manuals before using your power tool for the first time and keep them in a safe place for future reference.
Pictograms
All the pictograms attached to the machine are shown and explained in this manual.

WARNING
Warning where there is a risk of an accident or personal injury or serious damage to property.
NOTICE
Caution where there is a risk of damaging the machine or its individual components.
Engineering improvements
STIHL's philosophy is to continually improve all of its products. For this reason we may modify the design, engineering and appearance of our products periodically.
Therefore, some changes, modifications and improvements may not be covered in this manual.
The machine should only be provided or loaned to people familiar with this model and its operation. The KombiEngine and KombiTool user manuals should always be handed over with the machine.
Use your pole pruner for limbing only (removing or pruning branches). Saw wood and wooden objects only.
The machine must not be used for any other purposes – risk of accidents!
Only use guide bars, saw chains, chain sprockets and accessories that are explicitly approved for this power tool model by STIHL or are technically identical. If you have any questions in this respect, consult your dealer.
Use only high quality parts and accessories. in order to avoid the risk of accidents and damage to the machine.
Special safety precau­tions must be observed when working with the pole pruner because it operates at a very high chain speed, has very sharp cutters and a long reach.
Both user manuals (Kom­biEngine and KombiTool) must be read through attentively before using the unit for the first time and kept in a safe place for future reference. Non­compliance with the user manuals may cause seri­ous or even fatal injury.

See also notes on "Before Starting" in the user manual of the KombiEngine you are using.
Holding and guiding the machine
Make sure you always have good balance and secure footing.
Always hold your power tool firmly with both hands:
Right hand on control handle, left hand on the loop handle or handle hose, even if you are left-handed. Wrap your fingers and thumbs around the handles.
With the KM 94 R KombiEngine, always use the handle hose of the KombiTool as the left handle.
While working
In the event of impending danger or in an emergency, switch off the engine immediately by moving the slide control / stop switch/button to 0 or STOP.
This power tool is not insulated. Keep at least 15 m away from electric power lines – Danger of fatal electric shock!
Do not allow other persons within a radius of 15 m of your own position due to falling branches and ejected wood particles – Risk of injury! This distance must also be maintained in relation to objects (vehicles, window panes) – risk of property damage!
Keep the bar nose at least 15 m away from electric power lines . Electric current may also arc over from high­voltage cables at greater distance. Have the power switched off before starting work in the immediate vicinity of power lines.
Ensure that the engine idling speed is correct. The saw chain must not move when the throttle trigger has been released.
Check and correct the idle speed setting at regular intervals. If the saw chain still rotates, have your dealer check your machine and make proper adjustments or repairs – see the user manual of the KombiEngine.
Take special care in slippery, wet conditions, in snow and on slopes, uneven ground, etc. – Risk of slipping!
The gear head becomes hot during operation. To reduce the risk of burn injury, do not touch the gear housing!
Watch out for obstacles: tree stumps, roots – risk of tripping or stumbling!
Make sure you always have good balance and secure footing.
When working at heights:
Always use a lift bucket Never use the machine while
standing on a ladder or in a tree
Never work on an insecure support Never use the machine with just one
hand
Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.
Take breaks when you start getting tired or feeling fatigue – risk of accidents!

Work calmly and carefully – in daylight conditions and only when visibility is good. Proceed with caution, do not put others in danger.
Dust (e. g., sawdust), fumes and smoke produced while using the machine may be hazardous to health. If dust levels are high, wear a suitable respirator.
Do not touch the saw chain while the engine is running. If the saw chain becomes jammed by an obstruction, switch off the engine immediately before attempting to remove the obstruction – risk of injury.
Opening the throttle while the saw chain is blocked increases the load and reduces engine speed. The clutch then slips continuously and this causes overheating and damage to important components (e.g. clutch, polymer housing components) – and this can increase the risk of injury from the saw chain moving while the engine is idling.
If your power tool is subjected to unusually high loads 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". Make sure the safety devices are working properly. Never use a power tool that is no longer safe to operate. In case of doubt, contact a dealer.
To reduce the risk of injury, switch off the engine before changing the saw chain.
If you use a harness, ensure that the exhaust gas flow is diverted away from your body – Risk of fire!
Limbing
Hold the power tool at an angle. Do not stand directly underneath the limb being cut. Do not exceed an angle of 60° from the horizontal. Watch for falling wood.
Keep the work area clear – remove interfering limbs and brush.
Before sawing branches, establish an escape route and remove all obstacles.
0000003462_002
When performing the separating cut, position the bar against the branch near the hook. This will prevent the power tool from making jolting movements when you start the separating cut.
Start the cut with the saw chain at full throttle.
Always cut with a correctly sharpened, properly tensioned saw chain – the depth gauge setting must not be too large.
Perform cross-cut from the top downward to avoid the chain pinching in the cut.
If branch is thick or heavy, make a relieving cut – see chapter on "Using the Pole Pruner".
Exercise extreme caution when sawing branches under tension – Risk of injury! Always make a relieving cut on the compression side first and then perform the bucking cut at the tension side.
Be careful when cutting splintered wood – Risk of injury from ejected pieces of wood!
If working on a slope, always stand uphill or to the side of the branch which is to be sawn. Watch out for rolling branches.

English
Note when reaching the end of a cut that the power tool is no longer supported by the guide bar in the cut. The user must bear the weight of the machine – risk of loss of control!
Always pull the power tool out of the cut with the saw chain running.
Use the power tool for limbing and pruning only, not for felling – Risk of accidents!
Keep the saw chain away from any foreign objects: Stones, nails, etc. may be ejected and damage the saw chain.
If a rotating saw chain hits a stone or another hard object, sparks may be generated which may ignite easily flammable materials under certain conditions. Also dried-out plants and brushwood are combustible, above all in hot and dry weather. If there is a risk of fire, do not use your pole pruner near easily flammable materials, dry plants or scrub. It is mandatory that you ask the responsible forestry office about the current fire hazard.
Maintenance and Repairs
Service the machine regularly. Do not attempt any maintenance or repair work not described in the KombiTool and KombiEngine instruction manuals. Have all other work performed by a servicing dealer.
STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. STIHL dealers are regularly given the opportunity to attend training courses and are supplied with the necessary technical information.
Only use high-quality replacement parts in order to avoid the risk of accidents and damage to the machine. If you have any questions in this respect, consult a servicing dealer.
STIHL recommends the use of genuine STIHL replacement parts. They are specifically designed to match your model and meet your performance requirements.
To reduce the risk of injury,always shut off the enginebefore carrying out any maintenance or repairs or cleaning the machine. – Exception: Carburetor and idle speed adjustments.
Stopping the engine
before checking chain tension. before retensioning the chain. before replacing the chain. before rectifying problems.
Observe sharpening instructions – keep the chain and guide bar in good condition at all times for safe and correct handling of the saw. The chain must be properly sharpened, tensioned and well lubricated.
Always change the chain, guide bar and sprocket in good time.
Store chain lubricant in properly labelled, safety-type canisters only.

Chain Lubricant
For automatic and reliable lubrication of the chain and guide bar – use only an environmentally compatible quality chain and bar lubricant. Rapidly biodegradable STIHL BioPlus is recommended.
NOTICE
Biological chain oil must be resistant to aging (e.g. STIHL BioPlus), since it will otherwise quickly turn to resin. This results in hard deposits that are difficult to remove, especially in the area of the chain drive and chain. It may even cause the oil pump to seize.
The service life of the chain and guide bar depends on the quality of the lubricant. It is therefore essential to use only a specially formulated chain lubricant.
WARNING
Do not use waste oil. Renewed contact with waste oil can cause skin cancer. Moreover, waste oil is environmentally harmful.
NOTICE
Waste oil does not have the necessary lubricating properties and is unsuitable for chain lubrication.
