OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

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

Before operating the unit, stand in the operating position (Fig. 14). Check for the following:

•The operator is wearing eye protection and proper clothing.

•The right arm is slightly bent, and the hand is holding the shaft grip.

•The left arm is straight, and the hand is holding the J-handle.

•The unit is at waist level.

•The sweeper/blower is parallel to the ground and is positioned so debris is blown away from operator.

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 15) while operating the trimmer at high speed.

NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as cutting line becomes shorter

Each time the head is bumped, about 1 inch (25.4 mm.) of trimming line is released. A blade in the cutting attachment shield will cut the line to the proper length if excess line is released.

For best results, tap the Bump Head™ on bare ground or hard soil. If line release is attempted in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

NOTE: Do not rest the Bump Head™ on the ground while the unit is running .

CAUTION: Do not remove or alter the line cutting blade assembly. Excessive line length will make the clutch overheat. This may lead to serious personal injury or damage to the unit.

Some line breakage will occur from:

•Entanglement with foreign matter

•Normal line fatigue

•Attempting to cut thick, stalky weeds

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

TIPS FOR BEST TRIMMING RESULTS

•Keep the cutting attachment parallel to the ground.

•Do not force the cutting attachment. Allow the tip of the line 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.

•Cut from left to right whenever possible. Cutting to the right improves the unit's cutting efficiency. Clippings are thrown away from the operator.

•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;

•Following the previous trimming techniques

•What vegetation is being cut

•Where it’s being cut

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