Loading the Grass Cutting "Bump" Head

Do NOT attach or detach cutting tools when the engine is

running. • Ensure that parts are cool enough to touch before attaching or detaching cutting tools. • Do NOT use cutting equipment that is cracked, bent, chipped or damaged in any way. Replace damaged parts. • Use 1.6 to 3mm (1/16 to 1/8") plastic cutting line only. Non-plastic cutting line may not function properly and may damage the machine. • If the grass cutting head is dirty, clean it.

To load the grass cutting bump head with cutting line:

1. Remove the grass cutting head from the drive shaft. The thread on the drive shaft is "left-hand". This

means that you must rotate the grass cutting head to the right (clockwise) to unscrew it. To prevent the drive shaft from rotating as you loosen the grass cutting head, see here.

2. Place the grass cutting head (A) on a solid surface, then press down and rotate the "bumper" (B) to the

right (clockwise) until the cutting line holes are aligned (X) and you can see through the head.

Note: If there is remaining cutting line in the head, press down and rotate the "bumper" to the left (anticlockwise) one step, then pull the cutting line out from either side of the head. Repeat until you can pull the line out completely from the grass cutting head.

3. Insert the new line (C) through the grass cutting head so that the lengths of line on each side of the head

are the same (in other words, the head is at the centre of the length of cutting line).

4. Hold the grass cutting head firmly, then rotate the "bumper" to the right (clockwise) to wind in the cutting

line. Stop winding when there is approximately 50mm (2") of cutting line outside of the head.

• To use line feed action of the grass cutting "bump" head, tap it quickly against the ground while it is

spinning – line will feed out through the spinning action. Excess line will be cut by the trimming blade.

• When using the 3-blade cutter, it is recommended to NOT use the secondary cutting guard.

• Always use the strap, over the shoulder, and adjust it so the tool is comfortable to hold and operate.

Always use both handles to hold

the tool steady.

Use an arc or sweeping motion

when using the tool.

Using the Controls

• To activate the motor, press and hold the trigger safety button

(A), then squeeze the trigger (B). Once the motor is running, you can release the safety button.

• To use low-speed, while the motor is running, press the low-

speed button (C) – the low-speed indicator (D) illuminates.

• To use high-speed, while the motor is running, press the high-

speed button (E) Generally, most cutting attachments are most efficient at high-speed.

• To switch the motor off, release the trigger.

When cutting through thick grass

or brush, cut in several passes.

Understanding and Avoiding "Kick-Back" and Other Reactionary Forces

Reactionary forces can cause loss of control of the tool, and can result in serious, even fatal injury – use the tool in ways to avoid reactive forces at all times.

When the cutting attachment or chainsaw is rotating, many forces are created, such as the ability to cut. The contact point between the cutting tool and object to cut is critical, especially when using the chainsaw attachment. If the cutting tool is not used correctly, cutting forces may become "reactionary", in that instead of the cutting tool or chain rotating, a reactionary force is created. Many factors affect the occurrence and force of reaction, such as cutter speed, contact angle, density of material being cut, and cutting tool condition.

Kick-Back

"Kick-back" is a reactionary force that causes the tool to rotate against the direction of cut. Kick-back can also be thought of as the cutters "digging in" to an object and momentarily stop or significantly slow cutter rotation. For chainsaw attachments, kick-back can occur if the cutters at the tip of the chain bar – the "kickback zone", "digging in" to an object and momentarily stop or significantly slow saw chain rotation, which causes the tool to suddenly and quickly rotate backwards towards the operator. To avoid kick-back:

• Do NOT use the tip of the cutter for cutting or allow it to make contact with any object.

• Always hold the machine firmly with both hands when operating.

• Maintain cutter sharpness.

• Use extreme caution when re-inserting the cutter into an unfinished cut.

• Be alert to branches shifting or other forces that may close over or pinch the cutter.

Pull-In

"Pull-in" is a reactionary force that causes the cutter to pull forward in the direction of cut. Pull-in can also be thought of as the cutters on the non-cutting side of the cutting attachment being caught, pinched or "digging in" to an object and momentarily stop or significantly slow cutter rotation, which causes the tool to suddenly and quickly pull forward in the direction of cut. To avoid pull-in:

• Be aware of objects on the non-cutting side of the cutter and avoid making contact with them.

• Use cutters with greater numbers of teeth or blades.

Push-Back

"Push-back" is a reactionary force that causes the cutter to push backward against the direction of cut. Pushback can also be thought of as the cutters on the cutting side of the cutting attachment being caught, pinched or "digging in" to an object and momentarily stop or significantly slow cutter rotation, which causes the tool to suddenly and quickly push away from the direction of cut. To avoid push-back:

• Cut one piece of timber at a time.

• Avoid twisting the cutter when withdrawing it from material.

Grass Cutting "Bump" Head

A dirty grass cutting "bump" head may not feed out cutting line properly or reliably. • If the grass

cutting head is no longer serviceable, replace it. • If there is cutting line in the head, it may unravel when the head is disassembled. It is recommended to remove the cutting line. Load the cutting line after cleaning and reassembling the grass cutting head.

Inspection and Cleaning

Inspect the grass cutting "bump" head for dirtiness and debris etc that may affect the line feeding action. Clean or replace the grass cutting head as necessary. To clean the grass cutting "bump" head:

• Thoroughly clean the base (A) and "bumper" assembly (B) using a brush or similar to remove all traces

of grass, dirt etc from the parts. If desired, wash the parts in warm water and mild detergent, then rinse and dry.

Removal/Installation

1. Remove the grass cutting head from the drive shaft. The thread on the drive shaft is "left-hand". This

means that you must rotate the grass cutting head to the right (clockwise) to unscrew it. To prevent the drive shaft from rotating as you loosen the grass cutting head, see here.

2. Place the grass cutting head on a solid surface, then press in a locking tab (X) on the side of the head

until the upper and lower sections of the head can be separated.

To assemble, place the bumper assembly over the base – ensure that the holes in the sides of the bumper assembly are aligned with the locking tabs in the base – then press the cover down until it "clips" into place and is securely held by the locking tabs.

Check that the bumper can be moved in and out of the head and can be rotated in either direction – if not, the parts are not clean or not assembled correctly. To install the grass cutting head, see here.
