IDENTIFY & REMOVE YOUR ASSIST HANDLE

Your trimmer is configured with one of many types of assist handles. You must remove the current assist handle and install the 24” J-handle (included) in order to use the TBBC attachment.

Consult your trimmer’s manual to determine what type of handle you have. Follow the instructions outlined in the manual in order to remove the current handle and its clamps, screws, nuts, bolts or other hardware.

NOTE: Your trimmer may be equipped with a small

J–handle. This small handle is NOT an acceptable substitute for the larger J-handle that is included with the TBBC. Remove the smaller J-handle so you can install the larger, 24-inch handle.

Before you can use the TBBC attachment, you must make some adjustments to the trimmer or trimmer/ brushcutter that you are attaching the TBBC to. You will have to:

• Remove your current assist handle

• Install the supplied 24” J-handle

• Install the shoulder strap clip (if necessary)

• Attach/adjust the shoulder strap These instructions are explained on the next couple

pages.

To comply with

safety regulations, you MUST use the large 24” J-handle that is included with the attachment when operating the TBBC. The handle is required as a barrier bar to the brush blade.

WARNING:

USING THE CUTTING BLADE

To establish a rhythmic cutting procedure:

• Plant feet firmly, comfortably apart.

• Bring the engine to full throttle before entering the material to be cut. At full throttle the blade has maximum cutting power and is less likely to bind, stall or cause blade thrust (which can result in serious personal injury to the operator or others).

• Cut while swinging the upper part of your body from left to right.

• Always release the throttle trigger and allow the engine to return to idle speed when not cutting.

• When you are finished, always unsnap the unit from the harness before taking off the harness.

• Maneuver the unit in the opposite direction as the blade spins, which increases the cutting action.

Always wear eye,

hearing, foot, body protection and the shoulder strap to reduce the risk of injury when operating this unit.

WARNING:

Do not use the

cutting blade for edging or as an edger. Severe personal injury to yourself or others can result.

WARNING:

ade thrust may

occur when the spinning blade contacts an object that it does not immediately cut. Blade thrust can be violent enough to cause the unit and/or operator to be propelled in any direction, and possibly lose control of the unit. Blade thrust can occur without warning if the blade snags, stalls or binds. This is more likely to occur in areas where it is difficult to see the material being cut.

WARNING:

OPERATING INSTRUCTIONS

HOLDING THE UNIT

Before operating the unit, stand in the operating position (Fig. 12). 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 J-handle

• The unit is at waist level

• The cutting blade is parallel to the ground and easily contacts the grass without the need to bend over

Once you are in the operating position, hook the shoulder strap to the unit. Check the length of the strap before operating. If it needs adjustment, refer to Step 4 of Install the Shoulder Harness.
