Do not use a cutting attachment without an approved cutting attachment guard. If an incorrect or damaged cutting attachment guard is installed this can cause injury.

WARNING: If the cutting attachment is

attached to a battery power unit, make sure that the front guard is installed.

• Make sure that the cutting attachment guard and front guard is not damaged. Replace the cutting attachment guard and front guard if it is damaged. (Fig. 22)

• Only use original spare parts.

1153 - 001 - 22.08.2019To 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
