OPERATION

OPERATING THE TRIMMER

See Figure 6.

WARNING:

Engine housing on gas power heads may become hot during trimmer operation. Do not rest or place your arm, hand, or any body part against the engine housing during trimmer operation. Only hold the trimmer as shown in Figure 6 with all body parts clear of engine housing.

Extended contact with the engine housing can result in burns or other injuries.

WARNING:

Always position the unit on the operator’s right side. The use of the unit on the operator’s left side will expose the user to hot surfaces and can result in possible burn injury.

WARNING:

To avoid burns from hot surfaces, never operate unit with the bottom of the engine above waist level.

Hold the trimmer with your right hand on the rear handle and your left hand on the front handle. Keep a firm grip with both hands while in operation. Trimmer should be held at a comfortable position with the rear handle about hip height.

Always operate trimmer at full throttle for gas power heads or with the switch trigger fully pressed for cordless and electric power heads. Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and string head which may cause damage from overheating.

If grass becomes wrapped around the string head, STOP

THE ENGINE or MOTOR, disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect the plug from the power source for electric power heads, and remove the grass. Prolonged cutting at partial throttle will result in lubricant dripping from the muffler.

WARNING:

Always hold the string trimmer away from the body keeping clearance between the body and the product. Any contact with the housing or string trimmer cutting head can result in burns and/or other serious personal injury.

CUTTING TIPS

See Figures 6 - 7.

 Avoid hot surfaces by always keeping the tool away from your body. (Proper operating position shown in figure 6.)

 Keep the trimmer tilted toward the area being cut; this is the best cutting area.

 The trimmer cuts when passing the unit from left to right.

This will avoid throwing debris at the operator. Avoid cutting in the dangerous area shown in figure 7.

 Use the tip of line to do the cutting; do not force string head into uncut grass.

 Wire and picket fences cause extra line wear and breakage. Stone and brick walls, curbs, and wood may wear line rapidly.

 Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the line.

ADVANCING THE CUTTING LINE

Line advance is controlled by tapping the string head on grass while running motor at full speed.

 Run engine at full throttle for gas power heads or with the switch trigger fully pressed for cordless and electric power heads.

 Tap the bump knob on ground to advance line. The line advances each time the knob is tapped. Do not hold the knob on the ground.

NOTE: The line trimming cut-off blade on the grass deflector will cut the line to the correct length.

NOTE: If the line is worn too short you may not be able to advance the line by tapping it on the ground. If so, STOP

THE ENGINE or MOTOR, disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect the plug from the power source for electric power heads, and manually advance the line.

To advance the cutting line manually: wire for gas power heads, remove the battery pack for cordless power heads, or disconnect the plug from the power source for electric power heads.
