General notes on safety
Before you do any work with the high pruning saw, make yourself familiar with all operating parts. Practise using the saw (sawing logs on a sawhorse) and get an experienced user or a specialist to explain to you the function of the saw, the way of working, the techniques of sawing and the personal protection equipment.
Also, read the following safety instructions in order to prevent injury to people and damage to property:
Observe noise protection and other local regulations.
Improper maintenance and the removal of safety devices will cause a risk of serious injury.
GB IE
Electric safety:
Read the safety instructions in order to avoid injuries and material damage.
Protection against of electric shock:
•Connect the high pruning saw only to a plug socket with leakage-current- operated circuit breaker (l.c.o. circuit breaker) with a rated current of not more than 30 mA.
•Make sure that the mains voltage agrees with the information of the label.
•Protect the device against moisture. The device must not be wet and should not be operated in a moist environment.
•Check the device and the power cable with plug for damage before every use. Avoid body contact with earthed parts (e.g. metal fences, metal posts).
•Employ only extension cords, which are stipulated for use in the open air. The flexible lead cross-section of the extension cord must be at least 1.5 mm2. Always roll a cable drum completely out before use. Check the cable for damages.
•Damaged cables, coupling and plugs or connecting leads, not corresponding to the specifications, must be not be employed. Remove the plug immediately from the plug socket in case of damage or cutting through of the mains cable.
•If the power cable for this equipment is damaged, it must be replaced by the manufacturer, a customer service agent of the same or a similarly qualified person in order to prevent hazards.
Working with thehigh pruning saw:
•When felling timber, observe noise protection and other local regulations. Local rules may render necessary a
7
GB IE
suitability test.Ask the forest administration for details.
•Do not work with the high pruning saw when you are tired or after the consumption of alcohol or medication. Always take a break in good time.
•Always wear suitable working clothes during working, which allow freedom of movement. Included with this are a safety helmet, ear muffs, protective goggles or face protection, gloves with cut-protection, safety shoes with cutprotection and solid soles and protective trousers with saw protection.
•The high pruning saw is designed for two-handed operation. Never work with one hand or above shoulder height.
•Basically the mains cable is dragged behind the operator. The cable must always lead away from the high pruning saw towards the rear.
•Keep your working area tidy. Only start work if your working area is free from obstruction and you have planned a safe path of escape when felling timber.
•Ensure no people or animals are located near the field of action. Pay particular attention to children.
•Ensure you have a secure stance during sawing. Do not work on a ladder, in the tree or on unstable locations. Be very cautious carrying out work on a slope.
•Never start the high pruning saw before the chain bar, saw chain and sprocket chain wheel covering are correctly assembled.
•Ensure, before the switch-on, that the chainsaw is not in contact with any objects. Switch off the chainsaw before you relocate it.
•Do not work in the rain, bad weather or in a moist environment. Work only with good lighting.
•Ensure that the grips are dry and clean during work.
•Work only within the indicated range of performance. Do not employ any
low-powered devices for difficult work. Do not use tools for purposes for which they are not intended.
•Do not work with an high pruning saw which is damaged, incomplete or changed without approval of the manufacturer. Never use the high pruning saw with defective protective equipment. Do not use any tools where the switch cannot be turned on and off. Check the safety status of the high
pruning saw, in particular the chain bar, chain brake and the chain, before use.
•Damaged protection fittings and parts must be properly repaired or replaced at our Service-Center (see P. 34 for the address), unless otherwise stated in the manual.
•Pull out the power plug in case of nonuse of the device, before maintenance, cleaning or replacement of accessories. Ensure the chainsaw is switched off when you stick the plug into the plug socket.
•All maintenance operations, which are not indicated in these directions, may be carried out only by the customer service for chainsaws.
•Use only those accessories which are recommended in these directions.
•Place the claw stop securely with every cut and do not begin with the sawing before this.
•Be extremely careful during sawing small bushes and branches. The thin branch thicket can snag in the saw and whip in your direction or make you unbalanced.
•Carefully follow the maintenance, control and service instructions in this operating manual.
•Avoid sawing thin wood and trimmed timber.
•Pay attention to a possible spring-back during the sawing of a branch which is under stress, if the stress force of the wood is suddenly released. Danger of injury exists.
8
•Ensure during any location change that the saw chain is secured with the chain brake and the chainsaw is switched off and the finger does not contact the On/ Off switch. Carry the high pruning saw with the chain and chain bar pointing to the rear.Attach the chain guard for transporting the high pruning saw.
•Do not use the high pruning saw near inflammable liquids or gases. With nonobservance, fire or explosion danger exists.
Handling the device with care:
•Do not carry the device by the cable. Do not use the cable in order to pull the plug from the plug socket. Protect the cable against heat, oil and sharp edges.
•Keepthesawchainsharpandclean,in ordertobeabletoworkbetterandmore safely.
•Keep unused devices in a dry, closed location and out of the reach of children.
•Put on the blade protection cover when transporting the high pruning saw.
•Do not cut wood that is lying on the ground.
Precautions against springback
Beware of spring-back! Be careful of spring-back of the machine during work. There is danger of injury here. You can avoid spring-backs by exercising caution and using a correct sawing technique.
Spring-back is the designation for a light- ning-fast backwards impulse of the high pruning saw and the chain bar from the sawed object. It occurs if the rebound area (see Fig. 1, a) on the point of the blade is in contact with an object or if the wood jams the high pruning saw during cutting.

•Always grip the power saw firmly with both hands, with the right hand to the rear and with the left hand on the front handle. Thumb and finger must close over the handles securely.
•Do not saw with the point of the blade (see Fig. 1, b) or above shoulder height. Do not lean over too far during the sawing operation.
•You have better control when you saw with the bottom side of the chain bar and not with the top side of the chain bar.
•Be especially careful during the removal of branches. Ensure that there are no objects lying around on the ground that you can trip over.
•Pay attention to the instructions for sharpening and maintenance of the power saw.

Tensioning the saw chain
GB IE
chain tensioning device 5.
Turn this quick tensioning device clockwise to increase the tension.
In the same way, the tension of saw chain 1 can be decreased by turning anticlockwise.
3. Turn blade fixing screw 4 clockwise to retighten blade 2.
Where saw chain 1 has been newly tensioned, readjust the chain tension after a short period in operation.
Check the chain tension before each use of the high pruning saw.
Chain lubrication
The tension of saw chain 1 is important both for your safety and for the function of the high pruning saw. A correctly tensioned saw chain will increase the lifetime of your equipment.
Saw chain 1 is correctly tensioned if it can be pulled around blade 2 by hand (wearing gloves) without sagging.
When the saw chain is tensioned with 9 N (approx. 1 kg), the gap between the saw chain and the guide rail may not be more than 2 mm.
Blade 2 and saw chain 1 must always be oiled. Non-observance of this will result in increased wear on the blade and saw chain.
The high pruning saw is equipped with an oil automatic system. As soon as the motor is speeded up, the oil also flows faster to the chain bar 2.
