To check the blade
The blade is designed and manufactured to withstand
the loads that edging of a lawn involves.
• Check the blade for damage or cracks. A damaged
blade should always be replaced. (Fig. 23)
To check the support flange
• Check that the support flange is not cracked due to
fatigue or due to being tightened too much. Discard
the support flange if it is cracked. (Fig. 24)
To check the locknut
CAUTION: The nylon lining inside the
locknut must not be so worn that you can
turn it by hand. The lining should offer a
resistance of minimum 1.5 Nm / 13 in-lb.
The locknut must be replaced after it has
been put on approximately 10 times.
CAUTION: The locknut has a left-hand
thread. To tighten the locknut to much can
cause damage to the threads.
The locknut secures the cutting attachment on the
output shaft. Protect your hand from injury when
assembling, use the cutting attachment guard as
protection when tightening with a socket wrench.
1. When fitting, tighten the locknut in the opposite
direction to the direction of rotation of the cutting
attachment. To remove it, undo the locknut in the
same direction as the cutting attachment rotates.
(Fig. 25)
2. Tighten the locknut using a socket wrench to 15-20
Nm / 11-20 ft-lb. (Fig. 26)
Safety instructions for maintenance
WARNING: Read the safety instructions that
follow before you use the product.
• Always stop the engine/motor before you do work on
the cutting attachment. The blade continues to move
after the throttle/power trigger is released. If you
have a gasoline operated product, remove the spark
plug cap from the spark plug. If you have a battery
operated product, remove the battery. Make sure
that the cutting attachment has stopped fully before
you do work on it.
• Always wear heavy duty gloves when you repair the
cutting attachment. This is very sharp and can easily
cause cuts.
• Use only original spare parts for repairs.
• Keep the product away from children
Assembly
To install the front guard, battery power
units
1. Install the front guard on the front of the cutting
attachment guard. (Fig. 27)
2. Attach the bolt and tighten it.
To assemble the bevel gear
1. Insert the driveshaft into the bevel gearbox housing.
Turn the cutting attachment so that the shaft
engages in the bevel gear.
2. Attach the bevel gear box to the shaft tube aligning
the positioning holes.
3. Fasten the screw (A), then fasten the clamp bolt (B)
firmly, 6-8 Nm / 53-70 in-lb.
a) For model ECA850: (Fig. 28)
b) For model ESA850: (Fig. 29)
To assemble the cutting attachment
WARNING: Never use a cutting attachment
without without an approved cutting
attachment guard. If an incorrect or faulty
cutting attachment guard is fitted this can
cause serious personal injury.
1. Fit the drive disc (A) on the output shaft. Make sure
that the edge of the drive disc, that fits in the hole of
the blade, is facing outwards.
a) For model ECA850: (Fig. 30)
b) For model ESA850: (Fig. 31)
2. Lock the blade rotation by inserting the locking pin
(E) in the hole on the drive disc.
3. Fit the blade (B) on the drive disc.
4. Fit the support flange (C). The support flange must
be fitted so that its outer edge presses against the
blade.
5. Fit the locknut / blade mounting bolt (D). The
locknut / blade mounting bolt has a left-hand thread.
Tighten the locknut / blade mounting bolt to a torque
of 15-20 Nm / 12-15 ft-lb.
6. Remove the locking pin.
To adjust the cutting depth of the
cutting attachment
The cutting depth of the cutting attachment must be
adjusted before starting work.
1. Loosen the wing nut.
a) For model ECA850: (Fig. 32)
