Mounting the Shaft
N
Place the powerhead on a clean
and flat surface so that it is resting
on the guard plate and the machine
support (under the front handle).
N
Place the shaft (1) in front of the
powerhead and check that both
parts form a straight line.
N
Push back the hand guard (2) to
expose the thread (3) on the
pushrod.
N
Hold the hand guard in this position
and screw the shaft (1) onto the
pushrod's thread by hand – as far as
stop.
N
Position the 27mm open-end
wrench on the pushrod's hexagon.
N
Position the 34mm open-end
wrench on the shaft's hexagon.
Do not grip the shaft during
operation because its movements
will otherwise be transmitted
directly to your body – the
anitivibration system will be
bypassed – see also section on
"Vibrations" in "Safety Precautions
and Working Techniques".
