GENERAL SAFETY INSTRUCTIONS
Even when used as prescribed it is not possible to eliminate all
residual risk factors. Use with caution.
Keep guards in position
• Always keep guards in position, in good working order, correctly
adjusted and aligned. Never attempt to use a tool without
any guards supplied with it.
Remove adjusting keys
• Always check to see that keys, adjusting wrenches and
screwdrivers have been removed from the tool prior to
use.
Clean work area
• Accidents occur where work areas are cluttered or dirty. Keep
work areas clear of any un-necessary obstructions at all times.
Avoid working in areas where the floor may be slippery.
Dangerous environment
• Do not use tools in damp or wet conditions, or expose
them to rain. Provide adequate surrounding work space for tools
where there is a risk of explosion or fire from combustible
material, flammable liquids, flammable gasses or dust of an
explosive nature.
Children & pets
• Children and pets should be kept at a safe distance from the
work area AT ALL TIMES. Make sure the workshop is child
proof; lock all tools away where children can’t get access to
them. Remove batteries from all cordless tools.
Use the correct tool
• Do not force or attempt to use a tool for any other
purpose than its intended use.
Wear correct clothing and footwear

necessary.
Protect your head
• Wear safety goggles at all times, every day glasses are not
designed to offer any protection when using this product.
Normal lenses are not impact resistant and could shatter. Use
an approved face or dust mask when operation creates dust.
Hearing protection must be used at all times as the tool noise
level exceeds 80dB (A). Use a hard hat where there is a risk
of falling objects or a possibility of striking you head on level
obstructions.
Protect your self from vibration
• Many hand held power tools create vibration. Vibration can
cause disease. Wearing gloves will help maintain good blood
circulation in the fingers.

Switch off before connecting
• Ensure the engine is stopped before connecting any of
the accessories to the main body. If the power tool stops
unexpectedly make sure the engine is not running before

the blade.
Fitting the cutting line and spool assembly:
• Ensure that the cutting lines are correctly threaded through the
holes in the spool cover.
• Push the spool and line assembly onto the spindle (Fig.H).
• Make sure that the hexagonal recess on the spool is fully

removal spanner, twisting the bump knob anti-clockwise.
• Pull the bump knob out of the spool head and remove the
remaining cutting line (Fig.J).
• Cut the new line, Ø2mm and 6 meters long on two equal
lengths. Make a loop folded at each end of the two nylon
threads (already cut) and insert into one of the slots provided in
the center of the spool and wrap the line firmly clockwise.
• Introduce each end of the line to the eyelets in the spool holder (Fig.K).
The line should stick out 150mm each side.
• Screw the bump knob back on the shaft firmly.
CAUTION: After changing the line spool, run the tool under no load
for at least a minute to make sure that the line and the tool are both
operating correctly.
