• Always keep the cutting attachment near the ground.
  • Always do edging at full throttle/speed.
• Always slow the engine/motor to idle speed after each work operation. Long periods at full throttle/speed without any load on the engine/motor (i.e without the resistance that the cutting attachment exerts on the engine/motor when you are using the product) can lead to serious engine/motor damage.

• Be especially careful when you pull the edger towards you during work.

• If any object is hit or if vibrations occur stop the product immediately. 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. Check that the product is not damaged. Repair any damage.

• Sometimes grass or stones can get trapped in the cutting attachment guard and cutting attachment. Always stop the engine/motor before you clean it.

Safety devices on the attachment

WARNING: Read the warning instructions that follow before you use the attachment.

This section contains the attachment's safety features, its purpose and how checks and maintenance should be carried out to ensure that it operates correctly. See instructions under the heading Cutting attachment overview on page 6 to find where these parts are located on your attachment.

The life span of the attachment can be reduced and the risk of accidents can increase if attachment 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 servicing dealer.

WARNING: Never use an attachment with defective safety components. The attachment's safety equipment must be inspected and maintained as described in this section. If your attachment fails any of these checks, contact your service agent to get it repaired.

WARNING: All servicing and repair work on the product requires special training. This is especially true of the product's safety equipment. If your product fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your product is not a servicing dealer, ask him for the address of your nearest service agent.

To check the cutting attachment guard

WARNING: 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.

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.
