SAFETY INSTRUCTIONS  
Cutting equipment  
Machines safety equipment  
This section describes the machines safety equipment, its  
purpose, and how checks and maintenance should be carried  
out to ensure that it operates correctly. See the ”What is  
what?” section to locate where this equipment is positioned  
on your machine.  
The cutter is designed and manufactured to withstand the  
loads that edging of a lawn involves.  
Check the cutting attachment for damage or cracks. A  
damaged cutting attachment should always be replaced.  
The life span of the machine can be reduced and the risk of  
accidents can increase if machine maintenance is not carried  
out correctly and if service and/or repairs are not carried out  
professionally. If you need further information please contact  
your nearest service workshop.  
WARNING! Never use a machine with faulty  
safety equipment.The machine’s safety  
equipment must be checked and maintained  
as described in this section. If your machine  
fails any of these checks contact your  
service agent to get it repaired.  
!
Locking nut  
The locking nut secures the cutting attachment on the output  
shaft.  
WARNING! Always stop the engine before  
you work on any part of the cutting  
equipment.This continues to move even  
after the throttle is released. Check that the  
cutting equipment has stopped completely  
and remove the HT lead from the spark plug  
before you start any work on it.  
!
Protect your hand from injury when assembling, use the blade  
guard as protection when tightening with a socket spanner.  
Cutting attachment guard  
When fitting, tighten the nut in the opposite direction to the  
direction of rotation of the cutting attachment. To remove it,  
undo the nut in the same direction as the cutting attachment  
rotates. (CAUTION! The nut has a left-hand thread.)  
This guard is intended to prevent loose objects from being  
thrown towards the operator. The guard also protects the  
operator from accidental contact with the cutting attachment.  
CAUTION! The nylon lining inside the locking nut must not be  
so worn that you can turn it by hand.The lining should offer a  
resistance of at least 1.5 Nm. The nut should be replaced  
after it has been put on approx. 10 times.  
General safety precautions  
Check that the guard is undamaged and not cracked.  
Replace the guard if it has been exposed to impact or is  
cracked.  
WARNING! The machine can cause serious  
personal injury. Read the safety instructions  
carefully. Learn how to use the machine.  
!
Only use cutting attachments with the guards we  
recommend! See the chapter on Technical data.  
WARNING! A faulty cutting attachment may  
increase the risk of accidents.  
!
CAUTION! Please read the operator’s manual carefully and  
make sure you understand the instructions before using the  
machine.

as stones, broken glass, nails, steel wire, string, etc. that  
could be thrown out or become wrapped around the cutter  
or cutter guard.  
To ensure that people, animals, etc., do not come into  
contact with the cutting attachment or loose objects that  
are thrown out by the cutting attachment.  
Keep unauthorised persons at a distance. Children,  
animals, onlookers and helpers should be kept outside the  
safety zone of 15 m. Stop the machine immediately if  
anyone approaches.

SAFETY INSTRUCTIONS  
Basic working techniques  
WARNING! Sometimes grass or stones can  
get trapped in the cutter guard and cutter.  
Always stop the engine before cleaning.  
!
!
Safety instructions while working  
WARNING! Watch out for thrown objects.  
Always wear approved eye protection. Never  
lean over the cutting attachment guard.  
Stones, rubbish, etc. can be thrown up into  
the eyes causing blindness or serious injury.  
Always ensure you have a safe and stable working  
position.  
Always use both hands to hold the machine. Hold the  
machine at the side of your body.  
Safety instructions after completing work  
Make sure the cutting attachment has stopped before  
cleaning, carrying out repairs or an inspection.  
Disconnect the HT lead from the spark plug.  
Always wear heavy-duty gloves when repairing the cutting  
attachment.This is extremely sharp and can easily cause  
cuts.  
Use your right hand to control the throttle setting.  
Store the machine out of reach of children.  
Use only original spare parts for repairs.  
Make sure that your hands and feet do not come near the  
cutting attachment when the engine is running.  
When the engine is switched off, keep your hands and feet  
away from the cutting attachment until it has stopped  
completely.  
Always carry out edging at full throttle.  
Always keep the cutter close to the ground.  
Always slow the engine to idle speed after each working  
operation. Long periods at full throttle without any load on  
the engine (i.e. without the resistance that the cutting  
attachment exerts on the engine when you are using the  
machine) can lead to serious engine damage.  
Be especially careful when pulling the edger towards you  
during work.  
If any foreign object is hit or if vibrations occur stop the  
machine immediately. Disconnect the HT lead from the  
spark plug. Check that the machine is not damaged.  
Repair any damage.

ASSEMBLY  
Fitting the bevel gear  
Fitting the cutter  
Fit the bevel gear on the shaft.Turn the cutter so that the shaft  
engages in the bevel gear.  
Fit the cutter as follows:  
Position the bevel gear so that the slot aligns with the line on  
the shaft.

Check that the cutter is undamaged and not cracked.  
Replace the cutter if necessary.  
Lubricating the flexible drive shaft  
Check that the locking nut is tight.  
Weekly maintenance  
Inside the hollow drive shaft of the edger is a flexible drive  
shaft. This flexible drive shaft should be regularly lubricated  
every 25 hours in operation. Loosen the two screws on the  
bevel gear and remove it. The flexible drive shaft is easily  
removed from the hollow shaft by taking a firm grip on the shaft  
end. Lubricate the entire length of the flexible drive shaft and  
reinsert it in the hollow drive shaft. Turn the shaft while  
inserting it so that it correctly engages in the clutch. Refit the  
bevel gear on the hollow drive shaft and tighten the two screws.
