TRIMMER BLADE REPLACEMENT/ INSTALLATION

Always use original equipment manufacturer replacement blades. Blades other than those specified may make the engine overheat or fail.

To removing the trimming blades:

1. Remove the cutting head cap by pressing in on both cap tabs and then pulling down on the cap. (Fig. 7)

2. Turn the cutting head over and grab an individual blade near the cutting head and wiggle it up and down until blade comes loose. (Fig. 8)

3. Repeat step 2 until all blades are removed.

To install the trimming blades:

4. Take the new blade so that the loop at the end is facing away and to the right. (Fig. 8)

5. Place the loop onto the peg and adjust it so that it fits into the slot on the cutting head. (Fig. 8)

6. Press down on the loop end of the blade till it is securely in place.

7. Repeat steps 4 thru 6 until all 4 blades are in place. (Fig. 8)

NOTE: Make sure to place the blades so that they alternate in

color. Never place 2 yellow or 2 orange side by side.

8. Replace the cutting head cap, making sure to align the cap tabs with the cutting head tab slots. (Fig. 9)

9. Once the cap is in place, press down until the tabs snap and lock into place.

CLEANING

Use a small brush to clean off the outside of the unit. Do not use strong detergents. Household cleaners that contain aromatic oils such as pine and lemon, and solvents such as kerosene, can damage plastic housing or handle. Wipe off any moisture with a soft cloth.

STORAGE

• Check unit before storage to be sure the equipment is in safe working condition.

• Stop the engine or motor.

• Store the unit indoors, in a dry and locked place, out of the reach of children.

• Maintain or replace safety and instruction labels, as necessary.

• Store spare blades in a bag with a small amount of water. This will prevent the blades from drying out

and keep them flexible.

WARNING:

Always install all four blades, 2 yellow and 2 orange. NEVER install 1, 2 or 3 blades as this will make the trimming unit unstable and hard to control. Which could result in serious personal injury.

OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

Before operating the unit, stand in the operating position (Fig. 5). Check for the following:

• The operator is wearing eye protection and proper clothing

• With a slightly-bent right arm, the operator’s right hand is holding the shaft grip

• The operator’s left arm is straight, the left hand holding the handle

• The unit is at waist level

Some blade breakage may occur from:

• Entanglement with foreign matter

• Normal blade fatigue

• Attempting to cut thick or stalky weeds

• Forcing the blades into objects such as walls or fence posts

NOTE: Change all 4 blades once cutting performance becomes poor. TIPS FOR BEST TRIMMING RESULTS

• For best trimming results, it is recommended to use a combination of orange and yellow blades for the Vegetation Tasks with the corresponding throttle speeds listed below:

• Do not force the cutting attachment. Allow the tip of the blade to do the cutting, especially along walls. Cutting with more than the tip will reduce cutting efficiency and may overload the engine.

• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.

• Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward-backward or side-to-side motion. Cutting shorter lengths produces the best results.

• Trim only when grass and weeds are dry.

• The life of your cutting line is dependent upon:

• Proper adherence of explained trimming techniques

• What vegetation is cut

• Where vegetation is cut

For example, the blade may wear faster when trimming against a foundation wall as opposed to trimming around a tree.

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more.

Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 6).

WARNING:

Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit.
